AI used to create viruses not found in nature for first time

Summary

US researchers say they used artificial intelligence to create 16 viruses that do not occur in nature. The work could support medical research while raising concerns about how such systems might be misused.

The key shift is that AI has now helped generate viruses beyond known natural examples,

The AMOC stayed strong even as a major ocean “lifeline” nearly shut down

Summary

Seafloor sediments indicate that the flow of warm, salty water from the Indian Ocean into the Atlantic nearly stopped during a cold period about 3.4 million years ago. The Atlantic Meridional Overturning Circulation did not weaken as expected and became stronger in some regions.

The evidence shows that the AMOC can draw on compensating circulation changes rather than respond

Why it matters

The AMOC may be more resilient, and more regionally variable, than models built around a single dominant ocean connection suggest.

World’s most-used weedkiller disrupts honeybee brains

Summary

Researchers found that honeybees exposed to glyphosate for three days foraged 13 percent less and developed changes in brain chemicals linked to behavior, despite lacking the enzyme glyphosate targets in weeds. Reduced foraging across a hive could lower honey production, weaken pollination and threaten colony survival.

The important finding is that glyphosate may affect bees through neurological pathways unrelated to its

Why it matters

Even modest behavioral changes in individual bees can scale into serious losses for pollination and hive health.

Watch: Nasa astronauts conduct 6.5-hour spacewalk outside ISS

Summary

Astronauts Anil Menon and Jessica Meir completed a 6.5-hour spacewalk outside the International Space Station. They installed mounting hardware needed for the station's future solar arrays.

The spacewalk advances the station's power infrastructure before the new solar arrays arrive, extending its

Birds Are Dying. Clues Point to El Niño.

Summary

A major seabird die-off is prompting experts to examine whether an El Niño weather pattern contributed to the losses. The coverage also considers data centers, pollution, and other climate-related developments.

The immediate question is whether El Niño disrupted marine ecosystems enough to trigger widespread seabird

Climate change is making Cape Cod a Tiger Shark habitat

Summary

Warmer waters and available prey may be drawing tiger sharks farther north to Cape Cod. Scientists suggest that the region now offers conditions suitable for the species.

The key change is a northward expansion of habitat as ocean temperatures rise and food

A star’s violent death exposed a hidden supermassive black hole

Summary

Astronomers detected a dormant supermassive black hole about 30,000 light-years from its galaxy's center after it tore apart a passing star and produced a brief flare. The object may be the remnant of a swallowed galaxy or a black hole displaced by a galactic collision.

The decisive finding is that a black hole far from a galactic core can remain

Cell-inspired nanoreactor turns sunlight into hydrogen peroxide

Summary

Researchers developed a hollow nanoreactor that uses visible light to produce hydrogen peroxide more efficiently. Its internal cavity traps light, while an outer shell helps move protons through the reaction.

Forget the sperm race: Fertilization may depend on teamwork

Summary

An evolutionary study found that sperm cooperation occurs widely among arthropods, with coordinated groups emerging and disappearing repeatedly over hundreds of millions of years. The findings challenge the idea that fertilization is governed solely by competition among individual sperm.

The central change is conceptual: sperm performance can depend on collective behavior, not just speed
