Researchers from the University of California and NASA's Jet Propulsion Laborator (JPL), have detected a huge cavity under the Thwaites Glacier in Antarctica, which is often dubbed as 'the world's most dangerous glacier'. The cavity  covers approximately two-thirds of the footprint of Manhattan and is almost 948 feet tall! It is so large that it represents a chunk of the 252 billion tonnes of ice lost from Antartica every year. The melting of the glacier could lift the ocean levels by about 2 feet, with unthinkable consequences globally.

12-year-old Niharika Dwivedi&nbsp;from Noida&nbsp;donated almost ₹48,000 to send three migrant workers back home in Jharkhand&nbsp;via air. One of the migrant workers was a cancer patient and needed to go back home urgently amid the crisis. Niharika&nbsp;shared with news agency ANI&nbsp;that she gave away her pocket money, which she had been saving all this while.&nbsp;The devastating conditions of seeing the migrants walk back home urged her to contribute in some way. This act of kindness was her little way of giving back to the society amid the global pandemic.&nbsp;

Romanian shoemaker,&nbsp;Grigore Lup&nbsp;has&nbsp;found an innovative way to ensure that people practice social distancing as a safety measure&nbsp;amid&nbsp;the Covid-19 pandemic. He has designed 'long-nose' leather shoes that help keep a distance of at least&nbsp;one-and-a-half metres between people. The unusual pair comes in&nbsp;European size 75 and it takes Lup&nbsp;about one square metre of leather to make them!

The Doda administration in Jammu and Kashmir has launched a new initiative to test fruit and vegetable vendors as well as wholesalers for Covid-19. Those who test positive for the&nbsp; infection, will be given treatment and care. Almost 51 vendors came to the sample collection center to get tested on Sunday. Authorities aim to conduct tests on milkmen and butchers to avoid community transmission of the virus through random sampling.&nbsp;

A simple, non-invasive blood test may be able to tell how prostate cancer patients will respond to treatment, a new study by The Institute of Cancer Research in London suggests. The liquid biopsy, researchers believe, may also help pinpoint patients at a greater risk of a relapse and tailor treatment for those in more advanced stages of the illness. For the study, the team of researchers from ICR and The Royal Marsden NHS Foundation analysed almost ,1000 blood samples from prostate cancer patients. The results concluded that the tests can detect 'traces of cancer in the bloodstream' and could help track the progression of the disease as well as response to treatment. Men who were found with a higher level of tumour DNA in the beginning of treatment had a worse outcome. Patients were monitored with repeated blood tests and those who responded to treatment saw a fall in the cancer DNA.

Bird enthusiasts and researchers are making the best use of the lockdown&nbsp;period which has lowered noise pollution in our surroundings significantly. The first global public sound map of the morning bird song has been created where people have shared over 3,000 recordings of bird chorus at down on the Dawn Chorus website. The project is&nbsp;led by Prof Michael Gorman&nbsp;who told Guardian, 'suddenly, the natural world can be heard more clearly.' According to early findings, Gorman&nbsp;says that&nbsp;records indicate that spring now occurs two weeks earlier than 15 years ago. The spring chorus project will help in the creation of art and help scientists study long-term changes in bird habitats.&nbsp;

As protests keep growing in US in the wake of a black man's death at the hands of a policeman, two rival brands emerge united in support. Sports and footwear giant Nike posted a video inverting its tagline&nbsp;'Just Do It' to 'Don't Do It,' in which the brand urged people to 'be a part of the change.' Adopting a united front against racism, its competitor adidas retweeted&nbsp;Nike's video, writing 'together is how we move forward.' Fans of both the brands wholeheartedly supported the effort as they mourn the loss of George Floyd and many more like him.&nbsp;

According to the World Health Organisation, since Covid-19&nbsp;primarily&nbsp;affects the lungs, smokers are at a higher risk of developing severe disease and death. Chewing tobacco, on the other hand, leads to increased production of saliva and thus the urge to spit.&nbsp;Spitting in public places could enhance the spread of the virus. Tobacco is also a major risk factor for heart disease, cancer and diabetes that put people with these conditions at higher risk for developing severe illness when affected by Covid-19.&nbsp;However, there are no peer-reviewed studies that evaluate the direct risk of Covid-19 with tobacco use. The WHO cautions that&nbsp;the act of smoking involves contact of fingers with the lips, which increases the possibility of transmission of viruses from hand to mouth.&nbsp;Smoking waterpipes&nbsp;or e-cigarettes&nbsp;often involve the sharing of devices, mouth pieces and hoses, which could also facilitate the transmission. WHO recommends&nbsp;that if you smoke, now is a good time to quit completely.&nbsp;Within 2 to 12 weeks of quitting, circulation will improve and the lung function increases, says the&nbsp;health body.&nbsp;&nbsp;

An experimental diagnostic test&nbsp;that can visually detect the presence of the novel coronavirus in 10 minutes has been developed by scientists from&nbsp;the University of Maryland School of Medicine. A study published in the journal&nbsp;ACS Nano&nbsp;states that the test uses a simple assay containing gold nanoparticles to detect a colour change in the presence of the Covid-19 virus. Indian-origin lead author of the study Dipanjan&nbsp;Pan told PTI&nbsp;that based on preliminary results, the new test that only needs a nasal swab or saliva sample may detect RNA material from the virus as early as the first day of infection. However, scientists added that more clinical studies are needed to ascertain the effectiveness of the test.&nbsp;

To mark this year's World No Tobacco Day, the World Health Organisation wants the highlight the importance of protecting teenagers from falling prey to the addiction. According to WHO estimates, nearly 90 per cent of smokers start smoking before they even turn 18 and more than 40 million young people aged 13-15, have already started to use tobacco. In fact,&nbsp;smoking e-cigarettes and hookah pipes, which are often marketed as 'safer' alternatives to conventional cigarettes are harmful, addictive, and increases the risk of developing heart and lung disease, the health body pointed out. With more than 15,000 flavours like bubble gum and candy, youngsters chances of smoking are now doubled.&nbsp;

Indian globally renowned sand artist Sudarsan&nbsp;Pattnaik&nbsp;has created a 50-feet sand sculpture to mark World No Tobacco Day. The artist from Odisha&nbsp;created the sand art at Puri&nbsp;Beach and wrote the piece aims to 'create awareness about the harmful effects caused due to tobacco' on Twitter. The artist has been creating artworks to mark this day for many years.&nbsp;

Jack Rico is not your ordinary 13-year old. The brilliant teenager just graduated from the Fullerton College in California with four associate's degrees and he did it in just two years! In the school's&nbsp;107-year-old history, Rico is the youngest to achieve the feat. He majored in history, human expression, social behavior and social science and he maintained a&nbsp;4.0 GPA&nbsp;in all of them. He will now be studying history at the University of Nevada in&nbsp;Las Vegas.

May 31 marks World No Tobacco Day. In addition to raising awareness, the initiative&nbsp;recognizes the efforts of countries, individuals and organisations from around the world in tobacco control.&nbsp;Finland's Ministry of Social Affairs and Health has received this year's 'World No Tobacco Day Award' issued by the World Health Organization. In 2016, Finland updated its Tobacco Act&nbsp;with a new objective to end the use of tobacco and other nicotine products by 2030. To reduce the appeal of e-cigarettes, especially among young people, Finland strictly regulates them and has introduced a ban on the use of flavours in e-cigarettes &ndash; one of the few countries globally which has introduced such policy measures.

The issue of tobacco smoking and risk for acute respiratory infection has become a talking point amid the Covid-19 pandemic. According to a paper published in The Lancet journal, robust evidence suggests that several mechanisms may increase the risk of respiratory tract infections in smokers.&nbsp;Smoking impairs the immune system and the ability to contain infection. The risk of contracting pneumonia&nbsp;is about 3&ndash;5 times higher in smokers and they&nbsp;are also 5-times more likely to contract&nbsp;influenza, states the paper. There's not enough evidence to support that tobacco smoking increases the risk of being infected by Covid-19. However, available studies indicate that&nbsp;current smokers have increased gene expression of ACE2 - the main receptor used by the Covid-19 virus to gain entry to host cells and cause active infection.&nbsp;The challenge for Covid-19 studies is to have large enough sample sizes with all variables that might be associated with tobacco smoking and health.&nbsp;

The signature red and white 'gamcha', that Prime Minister Narendra&nbsp;Modi donned as a mask while addressing the nation to announce the second phase of the&nbsp;lockdown&nbsp;in April, has inspired weavers in&nbsp;UP&rsquo;s Barabanki&nbsp;district. With the demand for the traditional cloth going up, a manufacturing unit has started making the gamcha&nbsp;in large numbers. The production caters to both the need for masks and employment opportunities in the region. Made with viscose cloth, 500 gamchas&nbsp;have already been delivered. E-commerce companies in Kanpur are also buying these gamchas&nbsp;and selling them online.&nbsp;

Members of the National Youth Orchestra of Great Britain and international artists came together to perform a section of "Jupiter" from English&nbsp;composer Gustav Holst's&nbsp;famous suite 'The Planets'. The orchestra invited performers of all levels from around the world to participate in the socially-distanced concert. The performance followed the orchestra's previous virtual collaborations which have been a success.&nbsp;

Scientists from the&nbsp;University of Cambridge have found that the ice sheets of Antarctica retreated&nbsp;at the speed of up to 50 meters a day at the end of the last Ice Age. This means that they retreated&nbsp;ten times quicker than the fastest retreating sheets today! The researchers warn that if the current trend of climate change continues to weaken ice shelves, similar patterns of ice retreat could occur, with massive consequences for global sea levels. Researchers from the Weddell Sea Expedition studied the ridges on the seafloor and noticed stunning delicate patterns, giving an insight into past ice retreats.&nbsp;

UK Scientist Dr Alan Jamieson&nbsp;has captured the world's deepest octopus on camera. Discovered&nbsp;7,000 metres down in the Java Trench, on the floor of the Indian ocean, it is believed to be a "Dumbo" octopus species. Dr Jamieson's equipment called 'lander' filmed two octopuses - one on a drop to 5,760 metres and a second around 6,957 metres. The&nbsp;previous deepest reliable sighting was at 5,145 metres down. The discovery shows that octopuses can find suitable habitat across at least 99% of the global seafloor.&nbsp;
