Honda City 2020 road test review: It sets a new benchmark for the segment

Maruti Suzuki is going to town talking about how diesel doesn't make economic sense at the moment, Skoda has repositioned the Rapid to offer a more tempting deal over hatchbacks and compact sedans, the Toyota Yaris is still chanting its 'I've got seven airbags' tune and Hyundai has given the ICOTY-winning Verna a significant makeover. All this action in the executive sedan space is in preparation to take on the new Honda City.

The City not only established Honda Cars in India, but it has also been the defining model line for the segment. In keeping with times and the ever-changing demands of the Indian market, the City has changed many shapes and sizes and while the consumer welcomed it all, the recent City was ridiculed for having lost some of the premium sheen that made the original so popular. But restoring the premium factor for the brand as a whole has been priority number one at the big H's headquarters, and that is also one of the reasons why the Civic model line made a comeback to the Indian market.

Design

The City's look and feel, therefore, is all the more important this time around. The first step towards that is its claim of being the widest, longest and roomiest car in the segment. Putting numbers to it, the new City is 53 mm wider, 109 mm longer, and 6 mm lower, than the fourth-generation model that it will co-exist with. The design of the new City borrows heavily from the Honda Accord than the Civic, and that lends this car a relatively wide-bodied stance over a low-slung and sporty design akin to the Civic. The City's tail lights have often had an uncanny resemblance to BMW tail light designs and the new one follows in that tradition too. That also makes it the most premium tail light design in the category so far.

The headlights look more sophisticated in comparison, with their 9-pot array of LED lamps each. Of course, this design may not look unique anymore because we have seen it on almost every new Honda car and motorcycle. I believe that if the designers had their way, they would even put these headlamps on Honda's power generators and lawn-mowers! But it does look quite premium and having lived with a Civic for six months, I can tell you that this design element turns heads. The thick chrome grille that connects the headlights is a polarising design element though, and I would have preferred a sleeker design. A sportier gloss black unit could be made available later as a part of an RS trim (currently sold in Thailand) that Honda is said to be evaluating for the Indian market with a 1.0-litre turbo-petrol engine.

While the face looks distinctive, the defining angle for the new Honda City is the side profile, which shows off the car's increased proportions. Honda's designer says that the design of the new City is inspired by car drawings made by six-year-olds, and that probably explains the overtly long overhangs. Honda claims that despite the ground clearance being same as the fourth-generation City, the approach and departure angles are unchanged. But we ran a couple of ramp tests with both generations in a parking lot and the new one scraped its chin even at crawling speeds. Welcome to premium car tantrums.

The bigger design inspiration for the new City comes from the Japanese Katana sword, which arcs a seamless crease from the headlights to the tail lights. It also gives the City a broader and longer nose, that has allowed a proportionately long boot as well, which encloses 506 litres of cargo space.

Cabin

While the dimensions have increased over the last generation City, the wheelbase remains unchanged at 2,600mm. Space was never a concern for the City, but by increasing the tread, Honda has improved on the shoulder space, while more knee room and foot space at the rear has been achieved by making the front seats slimmer like they did with the Amaze. But they have also made the cushioning three times thicker, and a little bit firmer too. The top trims drape the seats in faux leather which feels good to the touch, while the new contouring and bolstering gives the occupants a snug yet comfortable fit. Ingress and egress have no noticeable change.

The City had started feeling plasticky and some materials felt low-rent compared to the competition, but the new one fixes that by leaps and bounds. The dashboard design is new and the fit and finish is excellent. There is faux-wood trim, which manages to look pleasing, the stitches on the dashboard are real and Honda has added soft-touch materials on common touchpoints, which enhances the premium feel. I also like the knurled finish for the HVAC knobs, which are backlit and have reassuring clicks that complement the tactile feel of the rest of the switchgear and the new roll-and-click switches on the steering.

Taking prominence on the dash is an 8-inch touchscreen infotainment system, which, apart from satellite navigation, Apple CarPlay and Android Auto, also gets WebLink connectivity and connected tech. But unlike some of its rivals, there is not a hint of the connected features or even the (Idea) network status on the infotainment screen, all those features are controlled through the revised Honda Connect app on our phones. All the Jap brands seriously need to work on better user interfaces for these kinds of systems and the City is yet another example of that.

The phone app is an enhanced version of the one used by the current range of Honda cars and allows all the connected features you expect in 2020 – geofencing, vehicle tracking, service alerts, payment gateway, vehicle theft notification, remote immobilisation, emergency service, crash notifications etc. On the automatic variant, you can also use the app or the car's key (in close proximity) to remotely start the car for up to 10 minutes to pre-cool the cabin. But the party piece is the Alexa remote capability.

Not to be confused with Alexa Auto, the Alexa remote essentially is a new capability for your preferred Alexa device to communicate with the car. So you can simply ask Alexa to track the car, check fuel status, remind you about the next service or PUC certification expiry etc. It is, however, a one way communication, meaning you can't ask the car's infotainment to communicate with the Echo at home and ask it to brew a cappuccino on your fancy Alexa-enabled coffee-maker in time for your arrival. But it's a nice feature to have and opens new doors and possibilities.

Along with the wheelbase, Honda has also retained the suspension mounting points of the previous-gen City, but the chassis has been revised with newer material ratios for enhanced rigidity. They have also used new bonding and insulation techniques to make the cabin quieter. While that has noticeably reduced all mechanical noises filtering into the cabin, there is a fair bit of booming sound on the concrete surface and wind noise coming off the wing mirrors beyond 80kmph. The wing mirrors have been repositioned to sit closer to the driver and create a larger ridge between themselves and the new, slimmer A-pillars. The window sills have been placed lower too, creating a combination that makes for better cornering visibility. The left wing-mirror is also equipped with the blind-spot assistant camera from the Civic – a segment-first. While the blind-spot and reversing cameras are a good safety feature to have, their feed is noticeably pixelated on the relatively low-res infotainment screen (800x480p, WVGA).

Safety

Safety has been taken rather seriously with the new City. You can choose up to six airbags, ABS, EBD, Traction Control, vehicle stability control, hill start assist – all of which have helped the new City in earning a 5-star ASEAN NCAP rating. To that effect, Honda has added a 3-point seatbelt for each rear seat occupant, there is a tyre pressure monitoring and deflation warning system, and the auto headlamps will turn on even in the rains irrespective of how dark or bright the surroundings are. The car won't automatically turn on the hazard lights in the rain though, because the City knows it is the wrong thing to do. Be like the Honda City and don't be an idiot! In case of an accident or a mechanical malfunction, the aforementioned Honda Connect will also automatically contact emergency services and share the GPS coordinates for the car.

Powertrain performance and driving dynamics

The City's petrol option uses a 1.5-litre naturally-aspirated i-VTEC 4-cylinder engine. While its output is similar to the outgoing car, it is an all-new engine that finally gets a double-overhead-cam (DOHC) and valve timing control. The internals boast of revised materials, more efficient geometries and cleaner combustion than its SOHC counterpart. While the latter was well-known for its refinement and rev-happy nature, the new one improves further on those aspects.

The manual transmission on this engine is an all-new 6-speed unit that replaces the previous 5-speed transmission. It's got a lighter clutch pedal feel, the throws are nice and short (though not as short as the Civic) and have the typical slick operation that we love in Japanese cars. The 7-step CVT is a convenient option and works discreetly at city speeds. The modified CVT 'box is quicker than before to respond to throttle and brake inputs so pulling overtakes doesn't require much planning either. But after the manoeuvre, it keeps revving for quite some time before shifting to the next ratio. We often call this the 'rubber-band effect,' and while it is still pronounced at highway speeds, it isn't so evident in the city. After all, the city environment is ideally what you are choosing the convenience of the automatic for over the charm of the manual.

While the chassis is about 4.3 kg lighter, the engine has gained a bit of weight with the DOHC construction and the car has become heavier with the additional safety features, but Honda has compensated for that with the tuning. The engine has a linear power build-up, is tuned for a smooth low-end performance than before and has a strong punch between 3,000-6,000 rpm – it even sounds good in that zone. But both the gearboxes have a very different character and interact differently with the engine. Cruising at 100kmph on the highway needs about 1,800rpm with the CVT, but with manual, the engine needs 3,000 revs. Unsurprisingly then, the petrol CVT offers better highway economy (tested, see spec box) than the petrol manual (it reflects in the claimed figures too).

2020 Honda City specs sheet. Image: Overdrive

The 1.5-litre i-DTEC 4-cylinder diesel engine is carried over from the previous car, but it now has the assistance of a Diesel Particulate Filter (DPF) and NOx Storage Catalyst (NSC) for BSVI compliant emissions. Interestingly, the engine speed hasn't been strangled to achieve the emissions and at the same time, there is no need for AdBlue or Urea injection, so that is some clever engineering on Honda's part and one thing less to worry about for the owner.

 

2020 Honda City manual gear. Image: Overdrive

The 6-speed manual on the diesel is just as slick and effortless as in the petrol. The reverse gear has been changed from the constant mesh type to the selective sliding type for lesser jerks and easier operation. The noise insulation for the powertrain has been improved by a fair margin too and you will only hear the diesel clatter beyond 3,000 rpm. At slow speeds, the diesel City feels so refined now that the only thing telling you its fuel type are the pulsations in the clutch pedal.

While the suspension mounting points are similar to the outgoing car, their components have been redesigned for better endurance and up to 50 percent less friction. The real-world gains come in the form of a silent suspension operation even on poor road surfaces. How it ages, remains to be seen, but the ride feels more premium than what we have seen in the segment so far. The suspension tuning is still on the softer side, but the dynamics are better controlled. The ride is supple and hitting undulations even at highway speeds doesn't unsettle the car. The top-spec City still rides on skinny 185/55-R16 tyres but the floaty feel beyond 120kmph that we complained about with the previous City has been ironed out in the new one.

A precise, well-weighted steering setup that the new City benefits from, certainly has a big role to play in imparting confidence. It is complemented by sharp and progressive brakes. While the handling dynamics are now one of the best in the category, I would recommend fatter and gripper rubber if you are a driving enthusiast. But for the urban commuter the stock options from Bridgestone or Goodyear that ship with the car, are more than capable.

The handling characteristics of all the three variants are very closely matched, but the diesel engine runs out of breath far earlier than the petrol, so if I was choosing I would go with the petrol manual. Do take a look at the spec sheet to see how the three cars fared in our initial tests. We also managed to squeeze in a highway fuel economy test to add perspective, but the city and overall economy figures will come later with a road test.

Verdict

Having driven the updated Rapid and Verna in the same week as the City, it isn't hard to see that the new City feels like a generation change over the current segment dwellers. The infotainment system leaves me wanting for a better user interface since it is a large contributor to the feel-good factor. But apart from that, I don't see any flaws worth highlighting in the car. The new City is perfectly aligned with Honda's strategy of restoring the premium brand image and it achieves that quite well with its plush cabin, superior ride and an exciting new powertrain that reminds me of the original and tickles the enthusiast in me. In a nutshell, then, the new City has followed in the tradition of its predecessors of setting a new benchmark for the segment.

Asteroid Day 2020: Raising awareness about threat posed by near-earth asteroids, since 2016

In December 2016, the United Nations General Assembly declared June 30 as the International Asteroid Day, to be observed annually.

The day is aimed at creating awareness among the people regarding the near-earth objects (NEO) that can be “potentially catastrophic threats” to our planet. Comets and asteroids constitute NEOs.

According to the UN, the International Asteroid Day focuses on raising public awareness about the “asteroid impact hazard” and to inform the public about the “crisis communication actions to be taken at the global level in case of a credible near-Earth object threat”.

112 years ago today, an asteroid impact rocked Siberia

The UN General Assembly chose June 30 to mark the anniversary of the Tunguska Event in Russia.

On 30 June 1908, an asteroid fell on the Podkamennaya Tunguska river area in Siberia, Russia. The impact left behind “little evidence of its origin except flattening 5,00,000 acres of uninhabited forest, scorching the land, creating glowing clouds and producing shock waves that were detected around the world”.

This event is considered to be the most impactful asteroid impact event in recorded history.

In order to highlight the threat that the NEOs pose, awareness about the rocky bodies is needed. According to the National Geographic, asteroids are basically “chunks of rock that measure in size from a few feet to several miles in diameter”.

Image of comet 67P taken on 30 July 2015 by Rosetta's NavCam.

While most of the bigger asteroids are present in the asteroid belt between Mars and Jupiter, some occasional collisions or gravitational tugs send comets and asteroids toward the sun on “highly elliptical orbits, some close enough to Earth to pose a risk of impact”.

How are comets and asteroids different?

Comets tend to have “more chemical compounds” that vaporize when heated, such as water. They also travel in more elliptical orbits than asteroids do. Comets also appear fuzzier when observed through a telescope than asteroids do.

First COVID-19 vaccine candidate COVAXIN from India, gets DCGI approval for human trials

India's first vaccine candidate against the novel coronavirus, COVAXIN, has received a nod from the Drug  Controller General of India (DCGI) for further clinical trials Phase I and 2 in infected people. The vaccine is under development by Hyderbad-based biotechnology firm Bharat Biotech in collaboration with the Indian Council of Medical Research (ICMR) and the National Institute of Virology (NIV).

The clinical trials of the experimental COVID-19 vaccine in humans are scheduled to begin in July 2020, Bharat Biotech said in a note. COVAXIN has been expedited through national regulatory protocols, and subjected to "comprehensive pre-clinical studies" according to the company, which reports that the results are "promising" and "show extensive safety and effective immune responses".

Dr Krishna Ella, Chairman and Managing Director of Bharat Biotech, said, “The collaboration with ICMR and NIV was instrumental in the development of this vaccine. The proactive support and guidance from CDSCO has enabled approvals to this project. We worked tirelessly to deploy our proprietary technologies towards this platform.”

"The SARS-CoV-2 strain was isolated in NIV, Pune and transferred to Bharat Biotech. The indigenous, inactivated vaccine was developed and manufactured in Bharat Biotech's BSL-3 (Bio-Safety Level 3) High Containment facility located in Genome Valley, Hyderabad," the company added.

The company hasn't yet released details on how long the next steps are likely to take, when the vaccine might be launched in the market or its price.

In May 2020, Bharat Biotech went into a partnership with Thomas Jefferson University, Philadelphia, for an exclusive deal to develop a new vaccine candidate for COVID-19 that was invented at Jefferson. The vaccine was developed using an existing deactivated rabies vaccine as a vehicle for coronavirus proteins, according to a Business Line report.

Dr Matthias Schnell, an infectious diseases expert, and his lab at Thomas Jefferson reportedly developed the vaccine in January, after which they completed preliminary tests in animal models that showed a "strong antibody response in mice receiving it," the report adds.

In the past, vaccine maker Bharat Biotech has manufactured the H1N1 vaccine during the swine flu outbreak, and has over 140 global patents and 16 vaccines in its portfolio. The most significant of their developments is arguably the rotavirus vaccine Rotavac, a next-gen vaccine against a viral gastroenteritis that got pre-approval from the WHO after an Oxford laboratory found it safe and efficacious.

Among the first companies in India to announce a vaccine candidate was Ahmedabad-based Cadila Healthcare. Their candidate is currently in pre-clinical studies. Pune biotech firm Serum Institute and Panacea Biotec in Delhi, are also among the leading candidates from India to develop a COVID-19 vaccine.

The Gilead Sciences treatment candidate remdesivir was found to be effective in reducing the amount of time an infected COVID-19 patient spent in the hospital. Yet, a cure for COVID-19 has not been found.

Meanwhile, India reported over 18,000 cases on 29 June alone. The number of COVID-19 cases in India now stands at 5,66,840 and counting.

The Ministry of Home Affairs has released guidelines for Unlock 2.0, which is expected to come into force till 31 July.

TikTok removed from Play Store, App Store, company says it's in process of complying with govt order

On Monday, the Indian government banned 59 Chinese apps in the country that included TikTok, Cam Scanner, Shein, UC Browser, and others. As per a tweet by Ravi Shankar Prasad, Union Minister for Electronics and Information Technology, "For safety, security, defence, sovereignty & integrity of India and to protect data & privacy of people of India the Government has banned 59 mobile apps.

TikTok has become the first app that has been kicked out of Google Play Store and App Store after the announcement. As of now, users who already had the app installed on the phone are able to use the app just like usual. However, new users will not be able to download the app from the Android and iOS app store. Users who have an account on TikTok but unintalled it will also not be able to access the app anymore.

Meanwhile, TikTok has said that it is in the process of complying with the government’s order of banning the app and asserted that it has not shared information of Indian users with any foreign government, including that of China.

The short video-sharing company said it has been invited to meet with concerned government stakeholders for an opportunity to respond and submit clarifications.

"The Government of India has issued an interim order for the blocking of 59 apps, including TikTok, and we are in the process of complying with it. We have been invited to meet with concerned government stakeholders for an opportunity to respond and submit clarifications," Nikhil Gandhi, Head of TikTok, India said.

TikTok added that it continues to comply with all data privacy and security requirements under the Indian law and has not shared any information of its users in India with any foreign government, including the Chinese government.

"Further, if we are requested to in the future we would not do so. We place the highest importance on user privacy and integrity," he said.

Notably, this is not the first time that India has banned TikTok. Last year, it had come under fire for allegedly allowing ‘pornographic’ and ‘sleazy’ content to propagate, especially among its younger audience. It was also alleged that the app was proving to be a fertile hunting ground for pedophiles.

Sony WF-XB700 true wireless earphones review: One of the best TWS earbuds under 10K

Price: Rs 9,990

Rating: 4/5

Almost every second audio brand in India has launched their true wireless (TWS) earbuds in the market over the past few months, across various price points, ranging from under a thousand rupees to Rs 25,000 and beyond. While the category is fast evolving, there are still two glaring issues with most TWS earphones ― sound quality and battery life. Sony, with the launch of its latest WF-XB700 wireless earbuds, promises to address both those shortcomings while keeping the price under Rs 10,000. Let’s see if they succeed.

Sony-Charging Case 2-1024

Each earbud is fitted with a large 12 mm dynamic driver to produce the signature bass that the Sony XB series is known for.

Sony WF-XB700 True Wireless Earphones: Build, design and features (7.5/10)

These Sony buds have an unusual spiral design and feel a touch bulky. However, when you wear them, they don’t look weird or stick out of the ears awkwardly. Their build quality is solid and they’re made of good quality plastic, with a predominant matte finish and a touch of gloss. Silicone tips are included and you get four different sizes of ear tips in the bundle for different sized ears. The company states that each earbud weighs just 8 gm, but they do feel a tad heavier in the hand.

Each earbud is fitted with a large 12 mm dynamic driver to produce the signature bass that the Sony XB series is known for. The capsule-shaped charging case isn’t the most compact, and weighs around 46 gm. It can be charged using any Type-C USB charger. In case you do not have one, a USB-A to Type-C cable is bundled in the package. The earbuds aren’t touch-enabled and have one physical button each that lets you perform a handful of tasks like answering calls, play/pause tracks, jump to the next/previous track and increase/decrease the volume.

Sony WF-XB700--

The build quality of the earbuds is solid and they’re made of good quality plastic, with a predominant matte finish and a touch of gloss.

These earbuds are IPX4 rated sweat resistant, so it’s safe to take them to the gym or for a jog without worrying about sweat messing them up. The Sony WF-XB700 are Bluetooth 5.0 compliant and support the AAC codec. However, there is no support for AptX codecs, nor is there any active noise cancellation feature or NFC here. The audio doesn’t pause automatically when you remove the buds from your ear; something that one can expect on premium earbuds. Long story short, you just get the necessary features here and nothing fancy.

Sony WF-XB700 True Wireless Earphones: Comfort (7.5/10)

While the earbuds look bulky and seem a bit heavy in hand, they fit into the ears perfectly after a bit of adjustment, and a three-point grip holds them firmly in place. The weight distribution is quite smart too and you don’t feel any major discomfort or heaviness in the ear. However, it may take a few minutes to get used to their presence, and a little longer if you haven’t used TWS earphones in the past. Also, one needs to be doubly sure that the buds are locked into the ears well, else they tend to pop out.

sony-In Ear

The weight distribution of the earbuds is quite smart and you don’t feel any major discomfort or heaviness in the ear.

Though there is no active noise cancellation here, the earphone design and the right sized silicone tips provide fairly solid passive noise isolation even in a noisy place. So much so, that I couldn’t hear the sound of a running tap on a metal sink in front of me or the person speaking to me from a few feet away when the music was turned on at normal volume.

Sony WF-XB700 True Wireless Earphones: Performance (8/10)

Syncing the Sony WF-XB700 with the phone was a breeze. All you need to do is get the buds in pairing mode, find them in the list of Bluetooth devices on the phone, and connect. The connection stays strong for up to 10 metres without any obstructions in between, and there were absolutely no syncing issues or delays between the two buds either. However, if you need to pair these with a different device, it is advisable to disconnect them from the previous device (rather than just switching off Bluetooth on the phone) as they fail to show up in the device list at times if you don’t do that.

As I had mentioned earlier, there is a tiny physical button on each of the earbuds, but the instruction manual doesn’t explain the full extent of their functionality. After fiddling around a bit, I realised what they can do. The button on the left bud can be pressed once to increase the volume, and press and hold it to decrease it. As for the button on the right bud, single press pauses or resumes the audio, double click takes you to the next track and triple click to the previous track. Sony could have kept things a bit simpler here. If you can’t remember all that, you can simply do the needful directly from the phone.

The Sony WF-XB700 are sufficiently loud even outdoors, and there was no need to take the volume level beyond 70 percent during the course of my testing. It stayed between 50 and 70 percent throughout. As for the sound quality, though not perfect, it is one of the finest I have heard on TWS earphones. These earphones belong to Sony’s Extra Bass (XB) series, and understandably, the low frequencies are boosted. There is ample bass, but it is quite tight with a lot of thump. Yes, the extra bass does come at the cost of certain midrange frequencies; mids sound a bit suppressed occasionally, but not overly so.

No such issues with the highs though; they are reproduced very well and sound sharp without sounding harsh. There is ample detail in the sound output and the soundstage is pretty decent too. Though these earphones tend to be a bit bass-heavy, the engineers haven’t overdone it, and the overall sound is quite enjoyable. But at times I did wish for some kind of equaliser to tone down the bass in certain tracks.

Most genres of music sound good on these Sony earbuds, but they are best suited for Bollywood numbers, dance tracks and EDM, where the extra bass makes such music more fun. Rock or Metal doesn’t sound bad, but instrument-heavy tracks can be a bit of hit-or-miss on this pair. Having said that, I can safely say that the overall sound quality of the Sony WF-XB700 is among the best I have heard on TWS earphones, and arguably the best under Rs 10,000.

Sony WF-XB700 True Wireless Earphones: Call quality (8.5/10)

There is very little to complain about in this department. Things function as expected. The person on the line was clearly audible and I was heard loud and clear by the other person too. The voice doesn’t feel hollow or tinny, and is almost as good as you get when using the phone microphone. However, a bit of ambient noise can be heard when using these earphones outdoors; something for Sony to work on.

Sony WF-XB700 True Wireless Earphones: Battery life (9/10)

While most TWS buds last close to 3 hours on a single charge, Sony advertises a figure of 9 hours for the WF-XB700 on a full charge. In reality, I got close to 10 hours out of them, when listening to music primarily, with a bit of calling. That is as good a number as I have seen on TWS buds till date. The case carries enough charge to recharge these buds fully, but just once. While other TWS buds’ cases let you recharge them at least thrice, just a single recharge sounds below par. But let’s not forget that the single recharge here is worth 9 hours of playback, which is equivalent to almost three recharges on most TWS earbuds. Ideally, I would have preferred to see the charge on the case suffice for a minimum of two recharge cycles.

Sony-Charging Case -1280

Sony claims that when the buds are drained, 10 minutes of charge allows you an hour of music playback on the WF-XB700.

The battery status of the earbuds is visible on the phone they are paired with, but similar data for the case isn’t available. It takes about 2.5 hours to charge the buds fully and close to 3 hours to charge the case. Sony also claims that when the buds are drained, 10 minutes of charge allows you an hour of music playback on the WF-XB700.

Sony WF-XB700 True Wireless Earphones: Price and verdict

The Sony WF-XB700 wireless earphones can be purchased for Rs 9,990 with a one-year warranty. Given the price tag, we cannot call them budget TWS buds, and they don’t sound like them either. They aren’t as feature-rich as some that sell for half their price, but they get two most important things right where most TWS earbuds falter ― sound quality and battery life. We will continue our quest to find good quality TWS earphones for as low a price as possible, but for now, the Sony WF-XB700 are the ones to beat under Rs 10,000.

Pandemics could occur more frequently, be less manageable due to environmental degradation

Environmental degradation, including deforestation, land-use change and agricultural intensification, may make pandemics more likely and less manageable, according to a study.
The study, published in the journal Environmental Science and Policy, presents the hypothesis that disease risks are "ultimately interlinked" with biodiversity and natural processes such as the water cycle.

The researchers at the University of the West of England and the University of Exeter in the UK used a framework designed to analyse and communicate complex relationships between society and the environment.

They conclude that maintaining intact and fully functioning ecosystems and their associated environmental and health benefits is key to preventing the emergence of new pandemics.

The loss of these benefits through ecosystem degradation -- including deforestation, land use change and agricultural intensification -- further compounds the problem, according to the researchers.

This happens by undermining water and other resources essential for reducing disease transmission and mitigating the impact of emerging infectious diseases, they said.

"Ecosystems naturally restrain the transfer of diseases from animals to humans, but this service declines as ecosystems become degraded,” said study lead author Mark Everard, of the University of the West of England.

"At the same time, ecosystem degradation undermines water security, limiting availability of adequate water for good hand hygiene, sanitation and disease treatment," Everard said.

He said the disease risk cannot be dissociated from ecosystem conservation and natural resource security.

"The speed and scale with which radical actions have been taken in so many countries to limit the health and financial risks from COVID-19 demonstrate that radical systemic change would also be possible in order to deal with other global existential threats, such as the climate emergency and collapse of biodiversity, provided the political will is there to do so," said David Santillo, of the Greenpeace Research Laboratories at Exeter.

The researchers said the lesson from the COVID-19 pandemic is that societies globally need to "build back better", including protecting and restoring damaged ecosystems keeping the many values of nature and human rights at the very forefront of environmental and economic policy-making.

COVID-19 infected patients are more likely to suffer from strokes, a new study has found

COVID-19 is significantly associated with an increased risk of strokes, according to a study which says patients infected with the novel coronavirus should undergo aggressive monitoring for the neurological condition.

According to the researchers, including those from the Icahn School of Medicine at Mount Sinai in the US, COVID-19 infection is a risk factor for acute strokes.

In the study, published in the American Journal of Neuroradiology, the scientists assessed patients presenting to six New York City hospitals for suspicion of stroke between March to April.

"We conducted a retrospective case-control study of 41 cases and 82 control subjects matched by age, sex, and risk factors," the scientists wrote in the study.

After adjusting for age, gender, and risk factors, the scientists found that COVID-19 infection had a significant independent association with acute ischemic stroke -- caused by a clot that blocks a blood vessel in the brain.

Comparing the group of patients with stroke versus non-stroke, they showed a significantly elevated number of patients with COVID-19 infection among the stroke group after accounting for other known common stroke risk factors.

The researchers believe that patients with COVID-19 should be evaluated early for acute neurological changes.

"This is the first major peer-reviewed study to show that COVID-19 infection is a risk factor for acute strokes," Puneet Belani, study co-author from Mount Sinai Hospital.

"Patients with COVID-19 should be evaluated early for acute neurological changes, and timely workup should be performed in patients suspected to have stroke to reduce morbidity and mortality," Belani said.

Citing the limitations of the study, the scientists said the study involved only 41 patients diagnosed with COVID-19, adding that further studies involving a larger population may help validate the findings.

"Future endeavours may assess whether this relationship holds true in a larger population and with the pathophysiologic mechanisms inherent in COVID-19 that drive this association," they wrote in the study.

It's Asteroid Day 2020: Why you should care, and how to catch live events on asteroids today

Wherever in India you are, you're able enough to participate in Asteroid Day — an event meant to raise awareness about these small, rocky bodies, globally. On this day in 1908, a large asteroid impact flattened the forest in Tunguska, Siberia, leaving behind a crater (now a huge pond) spanning as fas as the eye can see on both sides from the centre.

Researchers argue that the meteor, which blasted millions of trees in the forest, just 'grazed' the Earth. The morning sky above Siberia on 30 June 1908 flared so bright and hot that a witness standing dozens of kilometers from the site thought that his shirt had caught fire, according to a LiveScience reportAn explosion, which followed the minute-long blinding brightness, smashed windows and knocked people off their feet in a town 60 km away, BBC reported.

"The sky was split in two, and high above the forest the whole northern part of the sky appeared covered with fire," another witness reportedly said in testimony. NASA estimated that the energy released by the blast was roughly 185 times greater than the atomic bomb dropped on Hiroshima in 1945.

More than 100 years later, new patchy forest grows at the site of the massive 1908 Tunguska explosion. Image courtesy: Sovfot/Universal Images

It has also been theorised that asteroids were a major player in the cataclysm that killed the last of the dinosaurs. An asteroid that hit Earth at an incline – roughly 60 degrees – maximised the amount of climate-changing gases that entered the atmosphere.

The consequences of the asteroid impact lasted a lot longer, researchers say, than the impact itself. It released sulphur into the air, jumpstarting a "nuclear winter" on the planet's surface, which not only wiped out the dinosaurs but caused 75 percent of life on Earth to go extinct.

Today, asteroids are a lot more than an object of scientific curiosity. Researchers are also studying rocks in space to understand what forms them, to map their path and make predictions about likely future impacts that pose a threat to Earth, and because asteroids are time capsules of the early solar system.

In fact, research into asteroids alongside advancements in satellite technology have revealed that small asteroids impact Earth very frequently. A map released by NASA's Near-Earth Object (NEO) Program reveals that small asteroids regularly enter Earth's atmosphere and disintegrate with a random location distribution around the globe. The map visualizes data gathered by American government sensors from 1994 to 2013.

Asteroidday.org, a multi-partner effort to spread awareness about asteroids and events associated with them, released a petition in 2014 for public support to launch education programmes for awareness about asteroids. They also called on governments to accelerate the funding of asteroid discovery programs.

The website is hosting a day-long live program, covering many interesting dialogues, explaining research, and an exhibition by the European Space Observatory (ESO) with asteroids on display. You can catch the livestream here.

Third penumbral lunar eclipse will take place on 5 July 2020: Time, duration and visibility in India

The year 2020 has already witnessed two penumbral lunar eclipses so far. The third penumbral eclipse or Chandra Grahan of the year is all set to take place on 5 July.

The lunar eclipse will be visible across much of North and South America and Africa. During the maximum phase, the moon may turn slightly darker than usual, according to timeanddate.com.

The penumbral lunar eclipse will start at around 8.37 am IST on July 5 and will go on till 11.22 am IST. The maximum eclipse will be at 9:59 am IST. It will last for approximately 2 hours and 45 minutes. However, it will not be visible from India as it is taking place during the day time.

A penumbral eclipse creates only a dark shading on the moon’s face.

According to NASA, a lunar eclipse occurs when the earth moves between the sun and the moon. When this happens, the earth blocks the sunlight that normally is reflected by the moon. Instead of the light reaching the moon's surface, the earth's shadow falls on it.

A penumbral eclipse creates only a dark shading on the moons face. If the moon passes through the dark central shadow of the earth, which is also called the umbra, a partial or total lunar eclipse occurs. However, if the celestial body passes through the penumbra or the outer part of the shadow, a penumbral eclipse occurs.

There are three basic types of lunar eclipses -- a subtle penumbral eclipse, a partial eclipse and a total eclipse.

Traditionally July's full moon is called a Buck moon because a buck's antlers are in full growth mode this period.  According to Forbes, the Buck moon eclipse will see about 35 per cent of the full Moon pass into the Earths outer shadow and lose some of its brightness.

The last Penumbral lunar eclipse of this year will take place on 29-30 November.

Coronavirus Outbreak: NASA develops a PULSE pendant that is supposed to help keep your hands away from your face

The novel coronavirus can spread through surface contamination, that means if you touch a surface that has the virus and then touch your eyes, nose or mouth you can get infected. Hence, apart from wearing a mask outside and frequently washing our hands, health authorities have also prescribed people to keep our hands away from the face.

 As it is quite difficult to do so in practice, a small team from NASAs Jet Propulsion Lab (JPL) has a pendant made. Known as PULSE, it is a 3-dimensional pendant that pulses, or vibrates, when a persons hand is nearing their face.

Anyone with a soldering tool, 3D printer, wires, coin battery, and a motor will be able to build the device. Image credit: NASA/JPL

A video clip on how the pendant functions have been uploaded on YouTube. As soon as you wear the pendant and reach for any part above the necklace, you will experience "haptic feedback from a vibration motor", simulating a nudge in your hands. This will readily remind you to keep your hands off of your face.

 The video adds that the pendant works most efficiently when worn 6 inches below the chin. Another important point to remember is that the pendant is only an add on device and is not meant to replace masks or respirators.

The official page of the PULSE pendant states that its simple and affordable technology can be easily replicated by individuals and companies so that it gets widely distributed.

A list of parts, STL files, and assembly instructions have been made available for the public by JPL as open source. Anyone with a soldering tool, 3D printer, wires, coin battery, and a motor will be able to build the device.

Google Doodle celebrates trans LGBTQ+ activist, drag queen, revolutionary Marsha P Johnson

On this day in 2019, a powerful LGBTQ+ rights activist, performer, and self-identified drag queen Marsha P Johnson was given the posthumous honour of "Grand Marshal" of the New York City Pride March.

In a decorative, colorful illustration by Los Angeles-based artist Rob Gilliam, the Google Doodle today celebrates the LGBTQ+ activist Johnson, who is widely credited as one of the pioneers of the LGBTQ+ rights movement in the United States. Johnson was born on 24 August 1945, in New Jersey as Malcolm Michaels Jr.

Honoring and celebrating Marsha P Johnson. Image: Google Doodle

After graduating high school in 1963, she moved to New York City’s Greenwich Village, which is a burgeoning, thriving community of LGBTQ+ people and culture. After she arrived, she legally changed her name to Marsha P Johnson. Her initial "P" was allegedly also her response to those who questioned her gender: "Pay It No Mind", as per a Google blog post on the doodle.

Johnson grew to be one of the most beloved and charismatic figures in the LGBTQ+ community. She is regarded as among the key leaders that brought about the 1969 Stonewall uprising — a key event and turning point in the global LGBTQ+ rights movement.

The year following the uprising, Johnson founded the Street Transvestite Action Revolutionaries (now 'Street Transgender Action Revolutionaries' or STAR) with fellow transgender activist Sylvia Rivera. In the USA, STAR was the first organization to be led by a trans woman of color and the first organisation to open the country's first shelter for LGBTQ+ youth.

In 2019, New York City announced plans to put up statues of Johnson and Rivera in Greenwich Village – one of the world’s first monuments in honor of transgender people.

Google put it best when it said, "Thank you, Marsha P Johnson, for inspiring people everywhere to stand up for the freedom to be themselves."

NASA's planetary scientist create a simulation to show how the different sunsets looks like on various planets

The National Aeronautics and Space Administration (NASA) has time and again presented information about interesting celestial events or phenomenon. This time, the space agency has come up with some simulations showing how the sunset would look on other planets of the solar system.

These were created by Geronimo Villanueva, a planetary scientist from NASA's Goddard Space Flight Center in Greenbelt, Maryland. He used a tool called the Planetary Spectrum Generator for the project. To validate the accuracy of his tool, Villanueva simulated known sky colours of Uranus and other worlds, said NASA.

The simulations show that during sunset on Uranus a bright blue colour in the sky fades into royal blue with hints of turquoise. NASA revealed that the blue-green colour in the sky comes from the interaction of sunlight with the atmosphere of Uranus.

Geronimo Villanueva, a planetary scientist from NASA's Goddard Space Flight Center in Greenbelt, Maryland, created the sunset simulations while building a computer modeling tool for a possible future mission to Uranus, an icy-cold planet in the outer solar system. The animations show all-sky views as if you were looking up at the sky through a super wide camera lens from Earth, Venus, Mars, Uranus, and Titan. Credits: Geronimo Villanueva/James Tralie/NASA's Goddard Space Flight Center

What happens is when sunlight falls on Uranus, hydrogen, helium and methane present in the atmosphere absorb the longer-wavelength, the red portion of the light. On the other hand, the blue and green portions of light, which have a short wavelength, get scattered as photons bounce off the gas molecules and other particles in the atmosphere.

In the animations, the white dot represents the location of the sun. The halo of light witnessed towards the end of the sunset on hazy earth is produced because of the way light is scattered by particles suspended in the cloud.

During the sunset on Venus, a bright yellow sky turns into orange, brown, and finally black when the sun dipped below the horizon. The average temperature on Venus is 471 degrees Celsius and its atmosphere is replete with carbon dioxide.

Similarly, the simulations show how sunset on Mars would look like. The colour of Mars sky becomes a mix of muddy brown and bright yellow as the Sun disappears.

Villanueva also included an Earth-sized planet outside our solar system named TRAPPIST-1e in his study, which he conducted while building a computer modelling tool for a possible future mission to Uranus.

The search for Pluto’s successor continues with Rubin Observatory, could Planet X be the answer?  

After discarding Pluto as the ninth planet in our solar system, there are currently eight planets. But astronomers are looking forward to discovering the ninth planet that is much larger than earth.

Called the Planet Nine or Planet X, the mass is hypothetical as of now and exists somewhere in the farthest regions of the solar system. Its existence was first calculated in 2014 by astronomer Scott Sheppard of the Carnegie Institution for Science in Washington DC and his collaborator Chad Trujillo of Northern Arizona University.

red and infrared images taken by the Ralph/Multispectral Visual Imaging Camera (MVIC). The bright expanse is the western lobe of the "heart," informally called Sputnik Planum, which has been found to be rich in nitrogen, carbon monoxide and methane ices. Image credit: NASA/JPL

Although calculations suggest the possibility of Planet Xs existence, it could not be visualised in outer space till now. However, with the development of Rubin observatory inching its final stages, the ninth planet is close to us now more than ever. The observatory will have a , which has been named in the honour of Vera C Rubin, credited with some of the earliest discoveries related to dark matter.

The Planet Nine had come into focus in 2012 when Sheppard and Trujillo found 2012 VP113, a world that follows a very elliptical orbit around the sun. Interestingly, its orbit was similar to that of another world called Sedna. Both had elongated orbits pointing in the same direction and were aligned.

 But these objects cannot form on such orbits, at least not on their own. Hence, there exists another large planet which should be between two to 15 times larger than Earth in size that was manoeuvring 2012 VP113 and Sedna in the orbits that they were in.

These studies were published in Nature magazine in March of 2014 and this gave rise to speculations regarding the ninth planet.

 In 2015 another world called the Goblin was found that had similar orbit. This gave precision into the calculations of detecting Planet Xs location in the solar system.

 Now, researchers are waiting for Rubin to start functioning, which is scheduled to start in 2022, in order to find the planet. The powerful survey telescope can scan the entire sky within a few days. Hence, if such a planet like Planet X exists, it will become clear.
