Nearly six years after it was launched, India’s second moon mission Chandrayaan-2 continues to provide valuable data on the satellite. In a new finding, scientists have found the possible presence of subsurface ice in lunar south polar regions. These were the findings of scientists from Physical Research Laboratory (PRL) who used observations from the Chandrayaan-2’s...

Air pollution cut India’s solar power output by 9.6% in 2023, study says
Aerosols in the air reduced the amount of solar power generated in India by 9.6% in 2023, equivalent to around 15 terawatt-hours (TWh), according to a new analysis published in Nature Sustainability. The same study reported that the global average loss due to the same cause in 2023 was 5.8%. Between 2017 and 2023, pollution-related...
How do lightning rods prevent lightning strikes from reaching people?
Climate change is making lightning strikes around the world more common and deadlier. Every year, around 24,000 people around the world are killed by such strikes; in India, lightning strikes killed 2,887 people in 2022. There have been petitions to declare this phenomenon a natural disaster in India so that its survivors can access institutional...
Indian researcher names newly discovered galaxy structure after Manipur’s Loktak Lake
An Indian researcher based in Japan has named a newly discovered large structure of galaxies after Manipur’s Loktak Lake, seeking to “immortalise” the northeastern state’s identity in the cosmos. Dr. Ronaldo Laishram, who led an international research team as a postdoctoral researcher at the National Astronomical Observatory of Japan (NAOJ), said the structure was studied...
The physics of thermometers, temperatures and cold atoms
People from Bengaluru should not be allowed to complain about their weather turning hot. The other day, as a namma friend called to express disappointment over their daytime temperatures reaching as high as 33 degrees, I wondered in what Awadhi words should I inform her about the pleasant 42 degrees here in Kanpur. The baked earth, the...
The evolutionary history of flowering plants are threatened with extinction
Climate change is not only pushing species to the brink of extinction, it is erasing a vast proportion of the ‘evolutionary history’ of the world’s flowering plants’ — or how these organisms relate to one another on the tree of life, which changes over time. No less than a fifth (21 %) of the world’s...
Webb telescope captures weather on exoplanet 700 lightyears away
“Cloudy with a chance of rain” — imagine astronomers turning into meteorologists and issuing weather reports like this, but for alien planets. According to a new study published in Science on May 21, scientists were able to use the NASA James Webb Space Telescope (JWST) to peer closely at an exoplanet nearly 700 lightyears away,...
How is the earth’s outer core changing?
A: The earth’s outer core is a voluminous liquid layer that lies around 2,800 km beneath the surface. This hot, churning sea is filled with molten iron and nickel. As the outer core moves constantly, it acts like a large generator, creating the planet’s magnetic field, which shields the earth from harmful solar radiation. Researchers...
Whole body scans: why investors love them but doctors hate them
When doctors express scepticism about whole-body scanning, a predictable counter-argument surfaces on social media within hours. Physicians, the theory goes, have a vested interest in keeping you undiagnosed. Healthy patients don’t fill hospital beds. Early detection threatens the treatment economy and the doctor is the last person you should trust to tell you whether to...
Dog brains shrank significantly by 5,000 years ago, thanks to humans
Domestic dogs have significantly smaller brains than their wolf ancestors. Researchers have long known that dogs’ brains shrank in the past, but when has been a mystery. Some theories also argue that strict aesthetic standards and intensive, selective modern breeding over the last 200 years could have been the cause. In a new study, researchers...
