Soil protection measures can make agri-photovoltaics more sustainable

Agri-photovoltaics combines electricity generation and agriculture on the same land—to ensure this works well in the long term, it is worth taking a closer look at the soil. Researchers at the Leibniz Centre for Agricultural Landscape Research (ZALF) have, for the first time, mea

Quantum computer simulates matter “popping into existence”

Scientists recreated a particle-forming process linked to the extreme physics of the early universe using a 13-ion quantum simulator. The breakthrough suggests quantum computers could eventually help researchers investigate how matter formed and evolved after the Big Bang.

Scientists gave worms magnetic bacteria. They lived 43% longer

A magnet-producing bacterium extended the average lifespan of C. elegans worms by more than 43% while helping protect their neurological and intestinal health. Researchers traced much of the effect to suppression of ferroptosis, a damaging form of cell death linked to iron buildu

Distant time crystals can somehow fall into the same rhythm

Researchers have shown that multiple time crystals inside a semiconductor can synchronize their oscillations, much like pendulum clocks gradually falling into the same rhythm. The coupling is carried by spin-polarized electrons, allowing time crystals separated by up to 40 microm

These massive stars could explain Webb’s strangest galaxies

Hubble observations of massive stars in metal-poor dwarf galaxies are revealing clues to why the early universe looks so unusual. Researchers found that stellar winds weaken sharply at extremely low metallicities, potentially allowing massive stars to retain more material and evo

These tropical trees breathe at night to survive drought

Some tropical trees have evolved a clever way to survive drought by taking in carbon dioxide at night, allowing them to keep their pores closed during the hot daytime and conserve water. By comparing three Clusia species, researchers discovered that this water-saving form of phot

Humpback whale mother may have mourned her dead calf for days

Researchers observed a humpback whale mother staying beside her presumed stillborn calf for hours and possibly days off Australia’s Gold Coast. She maintained eye contact and remained close to the calf in behavior resembling caregiving and nurturing. Scientists say the rare obser

This new concrete is stronger and pulls CO2 from the air

Researchers have created a concrete mixture that is both stronger and capable of absorbing carbon dioxide. The best formula, combining zeolite with bamboo biochar, boosted compressive strength by 7.48% and tensile strength by 15% compared with conventional concrete. It also captu
