The Council of Scientific and Industrial Research announced the winners of the Bhatnagar Prize 2022 after a year’s delay while Kerala reports another outbreak of Nipah virus. Find all the latest news, discoveries and findings that happened in the field of science this week.

NASA names chief of UFO research

NASA has named a new director of research into what the government calls “unidentified anomalous phenomenon,” or UAP, while the U.S. space agency’s chief said an expert panel that urged deeper fact-finding on the matter found no evidence of an extraterrestrial origin for these objects. Administrator Bill Nelson made the announcement about the new research chief – without disclosing the person’s identity – after the independent panel of experts recommended in a new report that NASA increase its efforts to gather information on UAP and play a larger role in helping the Pentagon detect them. UAP are better known to the public as unidentified flying objects, or UFOs.

Centre announces winners of Bhatnagar Prize after a year’s delay

After nearly a year’s delay, the Council of Scientific and Industrial Research (CSIR) has publicised the list of awardees for the Shanti Swarup Bhatnagar (SSB) awards for 2022, considered among the prestigious prizes for science in India. While usually announced on September 26 – CSIR’s Foundation Day – the prizes weren’t announced last year, without any official reason being ascribed. Last year, the Ministry of Home Affairs constituted a committee to review all the national awards administered by various science and medical ministries and whittled down some of them. The SSB awards were however retained. This year’s awardees constitute 12 scientists below the age of 45.

Ian Wilmut, a British scientist who led the team that cloned Dolly the Sheep, dies at age 79

Ian Wilmut, the cloning pioneer whose work was critical to the creation of Dolly the Sheep in 1996, has died, the University of Edinburgh in Scotland said on September 11. He was 79. Wilmut set off a global discussion about the ethics of cloning when he announced that his team at the university’s Roslin Institute for animal biosciences had cloned a lamb using the nucleus of a cell from an adult sheep. Initially referred to as “6LL3” in the academic paper describing the work, the lamb was later named Dolly, after the singer Dolly Parton.

One-third of TB patients received no payment for nutrition support

Undernutrition is the leading risk factor for TB disease. A 2022 study noted that 45% of people in India are undernourished, accounting for nearly 1.2 million TB cases each year. Yet, nutrition support became a part of the national TB programme only in April 2018 when Nikshay Poshan Yojana — a direct benefit transfer (DBT) scheme for nutritional support to TB patients — was launched. Under this programme, Rs.500 per month is credited into the account of a person with TB for the duration of treatment. As per the India TB report 2023, of the 2.4 million notified TB cases, only 1.6 million (66%) received at least one month’s payment in 2022 under the Ni-kshay Poshan Yojana programme. There has been very little increase in the number of beneficiaries in the last three years.

Over 95% chance of El Nino conditions from January-March 2024

There is a more than 95% chance that the El Niño weather pattern will continue through the Northern Hemisphere winter from January – March 2024, a U.S. government forecaster said, bringing more extreme conditions. El Nino is a warming of ocean surface temperatures in the eastern and central Pacific and can provoke extreme weather phenomena from wildfires to tropical cyclones and prolonged droughts. The naturally occurring phenomenon is already spurring calamities across the globe, with the stakes seen higher for emerging markets more exposed to swings in food and energy prices. “As El Nino strengthens to strong status, there is a good likelihood it will have an impact on the upcoming growing season for the southern hemisphere crop production areas,” said Chris Hyde, a meteorologist

Nipah virus breaks out again in Kerala

Nipah scare returned to Kerala, with two deaths reported from Kozhikode district. Four suspected cases are currently under surveillance and their samples have been sent to the National Institute of Virology, Pune. A Central government team of four experts has also been sent to Kerala to assist the State government in surveillance and reduction in the response time. According to the World Health Organization (WHO), Nipah has a relatively high case fatality ratio, and is an emerging zoonotic disease of public health importance in the South East Asia and Western Pacific WHO Regions

Over 75% of European bumblebee species threatened in the next 40-60 years

More than 75% of European bumblebee species may be threatened in the next 40-60 years according to worst-case-scenario projections of bumblebee populations, according to a paper published in Nature. Degradation of habitats and alterations of climate due to human activity are identified as key drivers of these estimated population declines. The findings underscore the importance of climate change mitigation policies to protect bumblebees.

Indian Space Research Organisation charted history this week as Chandrayaan-3 successfully landed on the moon’s surface, making it the fourth country to do so and the only country to do so at the south pole. Find this week’s latest findings and discoveries from the field of science.

Chandrayaan-3 lands on the south pole of Moon

At 6.03 pm IST on August 23, the Chandrayaan-3 lander touched down on the moon’s surface, in the south polar region. The landing followed a 19-minute sequence in which the spacecraft used its engines, thrusters, and a suite of sensors to guide itself from an altitude of around 30 km and a speed of 1.7 km/s down to the ground. The success made India the fourth country to have soft-landed a robotic instrument on the moon and the first to have done so in the moon’s south polar region. This elite stature also boosts other countries’ confidence in the Indian Space Research Organisation (ISRO), which built, launched, and now operates the Chandrayaan-3 instruments.

Sun-observing spacecraft sheds light on the solar wind’s origin

New observations by the Solar Orbiter spacecraft may provide an answer to the origin of solar winds. Researchers have said that the spacecraft has detected numerous relatively small jets of charged particles expelled intermittently from the corona – the sun’s outer atmosphere – at supersonic speeds for 20 to 100 seconds. The jets emanate from structures on the corona called coronal holes where the sun’s magnetic field stretches into space rather than back into the star. They are called “picoflare jets” due to their relatively small size. Scientists think that these jets could actually be a major source of mass and energy to sustain the solar wind.

New findings suggest that LK-99 is probably not a superconductor

In July 2023, a group of scientists in South Korea uploaded two preprint papers claiming that a lead apatite material called LK-99 was an ambient condition superconductor. The group’s two papers elicited a mixture of surprise and scepticism in the scientific community – surprise because of the apatite, and scepticism because of the history of superconductivity. A group from India from the CSIR-National Physical Laboratory, New Delhi, was one of the first to report that it didn’t find any signs of superconductivity in LK-99. As far as current evidence suggests, LK-99 is not a superconductor.

Missed childhood TB cases impede achieving 2025 goal

With childhood TB continuing to remain a “staggering problem” in India, “eliminating” TB by 2025 might be extremely challenging. Nearly 0.34 million children <15 years of age in India are estimated to get TB disease every year. While children in this age group are estimated to contribute about 13% of the total TB caseload, only 6% are notified. As per the 2022 WHO global TB report, last year, children aged less than 15 years across the world accounted for 11% of the total estimated incident TB cases. Notwithstanding the 56% estimated TB detection gap in children globally, India contributes nearly one-third to the global childhood TB caseload.  

The ‘weird’ male Y chromosome has finally been fully sequenced

Scientists have finally been able to sequence the Y chromosome in its entirety. The findings provide a solid base to explore how genes for sex and sperm work, how the Y chromosome evolved, and whether – as predicted – it will disappear in a few million years. The Y chromosome is male-determining because it bears a gene called SRY, which directs the development of a ridge of cells into a testis in the embryo. The embryonic testes make male hormones, and these hormones direct the development of male features in a baby boy. Without a Y chromosome and a SRY gene, the same ridge of cells develops into an ovary in XX embryos.

Tropical forests may be getting too hot for photosynthesis

A small percentage of leaves on trees in tropical forests may be approaching the maximum temperature threshold for photosynthesis to work, suggests a study published in Nature. An estimated 0.01% of all leaves currently surpass this critical temperature but there are uncertainties in the range of potentially critical temperatures in tropical trees. Modelling suggests that tropical forests can withstand up to a 3.9 degree C increase over current air temperatures before a potential tipping point, therefore action is needed to protect the fate of tropical forests under future climate change.

No emperor penguin chicks survived last year due to melting of Antarctic ice

The loss of ice in one region of Antarctica last year likely resulted in none of the emperor penguin chicks surviving in four colonies, researchers said. Researchers used satellite imagery to look at breeding colonies in a region near Antarctica’s Bellingshausen Sea. The images showed no ice was left there in December during the Southern Hemisphere’s summer, as had occurred in 2021. Researchers said it is likely that no chicks survived in four of the five breeding colonies they examined. Penguin chicks don’t develop their adult waterproof feathers until close to the time they usually fledge, in late December or January, scientists say.
