A study has revealed that watching less TV and spending that time on other activities could cut depression risk by up to 43%. Replacing 30 minutes of TV watching with sports could reduce risk by 18%, with physical activity at work or school by 10.21%, with leisure or commuting activities by 8%, and with sleep by 9%.

Scientists studying samples from NASA's Bennu asteroid have discovered amino acids, including glycine, and sugars. Unlike previous assumptions, these molecules formed in extremely cold space conditions rather than in liquid water. The findings suggest that prebiotic molecules could be common in space and may have been delivered to early Earth, offering new insights into the origins of life.

2,000-year-old Tamil inscriptions have been discovered in pharaohs' tombs in Egypt. The inscription was reportedly left by a Tamil trader who carved his name inside the 'Valley of the Kings' in the tomb dating back to 1600 BCE. The discovery is expected to provide new evidence of direct, two-way contact between ancient Tamil traders and Egyptians during the Roman period.

India's Samudrayaan program is uncovering the secrets of the deep. Leiogalathea samudragiri is a squat lobster with a striking orange shell and white patches on its legs. Discovered at a depth of 360 meters, this species thrives on underwater mountains, proving the Northern Indian Ocean is a hotspot for rare life forms.

Scientists at IIT Bombay have mapped how soot particles navigate the rolling hills of mucus in our lungs. While large particles crash and small ones drift, some Goldilocks particles bypass our defenses entirely. Understanding this is key to better drug delivery. This research is particularly relevant for residents of heavily polluted cities like Mumbai and Delhi.

Scientists have decoded the optimal room temperature at which older adults should sleep, with their study stating keeping a bedroom at 24°C (75°F) overnight can lower stress responses during sleep in older adults. The scientists said that this temperature is optimal for people aged 65 and above as it helps to normalise their heartbeats, reducing stress levels.

A team of scientists from New York University discovered a new type of time crystal that can float on a cushion of sound. These time crystals can interact independently with each other using sound waves, and in the process defy Newton’s Third Law of Motion, researchers stated. The findings expand the potential of using these particles in technology and industry.

A rare heart-shaped aurora borealis over Norway has captivated social media ahead of Valentine's Day, after photographer Kristoffer Vangen shared the stunning image on Instagram. He said he'd long hoped to capture shaped auroras, and addressed online scepticism by confirming the photo's authenticity with only routine colour adjustments. The natural phenomenon has earned widespread admiration.

India is testing "perennial rice", a game-changing variety from China that yields harvests for years without replanting. Trials in Odisha and Tamil Nadu reveal it cuts water use by 40% and reduces labour costs. With deep roots tapping subsoil moisture, this innovation could save India's depleting groundwater while boosting climate resilience.

A study flags hidden risks in Manipur's Imphal River Basin, revealing a 52-59% developmental gap despite 'good' Water Poverty Index scores. The report warns that climate stress, wetland encroachment, and urbanisation threaten water security across four districts. Experts urge shifting focus from infrastructure expansion to wetland restoration to address growing vulnerabilities.
