Geminid meteor shower is set to light up night sky and it's expected to peak on intervening night of December 13-14. As per Starscapes Zones, best time for viewing it in India is between midnight and 4 am on December 14. To view the meteor shower, one should try and find a place where city lights are not strong.

The Zoological Survey of India has discovered two new species of jumping spiders in Meghalaya. One species, Asemonea dentis, named for a tooth-like structure on the male, is only the third of its genus recorded in India. The second, Colyttus nongwar, named after Nongwar village, is just the second Indian species of the rarely documented Oriental genus Colyttus.

NASA has used a new image-processing technique called "X-arithmetic" with the Chandra X-ray Observatory to reveal how supermassive black holes shape galaxy clusters. By comparing different X-ray energies, the method highlights bubbles, jets, shock fronts and cooling gas in hot cluster atmospheres. The images showcase systems including Perseus, M87, Cygnus A, Abell 2052 and MS 0735+7421.

The James Webb Space Telescope has discovered an exoplanet, 'ultrahot Jupiter' WASP-121b, or Tylos, leaking two vast helium tails. Located 858 light-years away, the planet orbits its star every 30 hours. Extreme radiation heats its atmosphere to about 2,300°C, causing lightweight gases like hydrogen and helium to escape the planet, flowing into space, creating these tails.

Jakarta, Indonesia's capital and largest city, is sinking far faster than Venice, a study warned. Parts of the city subside 1-15 cm annually, compared with Venice's 0.2 cm. Nearly 40% of Jakarta already lies below sea level, with rising seas worsening flood risks by 2030. Experts link the sinking to groundwater extraction, soft delta soils, rapid urbanisation and heavy construction.

Inito, founded by Aayush Rai and Varun AV, has raised $29 million in a Series B round led by Bertelsmann India Investments, with Fireside Ventures participating. The funding will help the company expand beyond fertility testing into broader at-home hormone and health diagnostics using AI-engineered antibodies, as it works to make reliable, data-driven testing more accessible from home.

Ocean storms are accelerating melting beneath Antarctica's Thwaites and Pine Island glaciers, a Nature Geoscience study stated. Using new ocean measurements, researchers found swirling underwater eddies funnel warm water under ice shelves, intensifying ice loss. Thwaites, dubbed the 'Doomsday Glacier', is especially vulnerable as warm flows attack weak, grounded ice zones, melting them.

The brain becomes tired when a person engages in difficult mental tasks like making tough decisions for hours, which leads to the accumulation of glutamate in the brain's decision-making region called the prefrontal cortex. This built-up glutamate becomes toxic to the brain's neurons, making them less efficient and less willing to keep working, which the brain perceives as mental fatigue.

New findings from the COSMOS trial suggest daily multivitamins may modestly help older adults with poorer diets maintain healthier blood pressure. While no broad benefit was seen across all participants, those with normal baseline readings showed small improvements, indicating micronutrient gaps may play a quiet but meaningful role in long-term hypertension risk.

NASA has shared several stunning images of galaxy clusters containing supermassive black holes that erupt periodically. The images captured by NASA's Chandra X-ray Observatory show colourful jets of hot gas emitted by the black hole explosions. NASA said that mass of this hot gas is about five times higher than the total mass of all the galaxies in the cluster.
