96 Percent of Orbital Collision Risk Comes From Junk, Not New Satellites

ESA's newest debris count shows that almost all of low Earth orbit's collision risk comes from hardware nobody controls anymore. ISRO's satellites, and India's own new constellations, are the ones now dodging it.

An Atlantic Current Collapse Would Cut India's Monsoon Nearly a Fifth

Coverage of a collapsing Atlantic current keeps framing the food-security risk around Europe, the US and a list that includes India. Peer-reviewed modeling puts a specific number on India's exposure, and this year's monsoon already opened on the back foot.

India's Nighttime Heat Just Overtook Its Daytime Heat

Over the last century, India's afternoons warmed faster than its nights. Over the last decade, four independent data sources say that has flipped, and the flip is the one that matters more.

The Rare Metal That Made and May Doom a Heat-to-Electricity Breakthrough

A JNCASR, IISc and University of Sydney team has measured a voltage response to heat that blows past the ceiling conventional physics sets. The metal that makes it possible is one the world can barely supply.

Bihar's Answer to Nepal's Flood Fish Is a Ban, Not a Test

A Nepal glacier flood swept fish species nobody recognizes into Bihar's rivers and markets. The state can track the water to the exact cusec, but has no way to identify or test the fish, so it just told people not to eat any.

AI Can Design a Genome That Looks Like Nothing in Any Screening Database

Stanford researchers just used AI to write working virus genomes from scratch. The screening software built to catch dangerous DNA orders was designed to match known pathogens, not judge sequences no one has ever seen.

Delhi's 'Excess' Monsoon Label Hides Wild Swings From One District to the Next

IMD's seasonal number says Delhi's monsoon is 24 percent above normal. Its own district data, for the same day, show one part of the city drowning in surplus rain and another running dry.

The Night Sky Is Brightening Faster Than Satellites Can See

Citizen star counts show the sky brightening nearly four times faster than satellites can measure, because the instruments are blind to the exact light now spreading fastest, including through India's own streetlight rollout.

The World's Most Oxygen-Starved Sea Is Shrinking While the Rest of the Ocean Catches Up

A June 2026 review just proposed ocean deoxygenation as a new planetary boundary. Off India's west coast, the Arabian Sea has already run that experiment for decades, and the record it has produced is stranger than a warning.

A Light Monsoon Day Can Lose Four-Fifths of Its Rain to Dry Air

Scientists have finally measured how much of India's monsoon rain evaporates in midair rather than landing. On the driest days, drier air can erase most of the rain that a cloud actually produced.
