Living cells pay a hidden energy price not just to run chemical reactions, but to keep them on track and block all the alternatives. A new thermodynamic framework makes it possible to calculate these overlooked costs and compare different metabolic . ...

Researchers studying Caribbean whales and orcas have discovered two new viruses not previously observed in these animals. The viruses were found using advanced genetic sequencing of archived samples, revealing a previously invisible layer of marine . ...

When a huge earthquake struck near Kamchatka, the SWOT satellite captured an unprecedented, high-resolution view of the resulting tsunami as it crossed the Pacific. The data revealed the waves were far more complex and scattered than scientists ...

A meltwater lake that formed in the mid-1990s on Greenland's 79°N Glacier has been draining in sudden, dramatic bursts through cracks and vertical ice shafts. These events have accelerated in recent years, creating strange triangular fracture ...

CO2 can stimulate plant growth, but only when enough nitrogen is available--and that key ingredient has been seriously miscalculated. A new study finds that natural nitrogen fixation has been overestimated by about 50 percent in major climate models. ...

One of the most complete human ancestor fossils ever found may belong to an entirely new species, according to an international research team. The famous "Little Foot" skeleton from South Africa has long been debated, but new analysis suggests it ...

New research shows Karnak Temple was built on a rare island of high ground formed as Nile river channels shifted thousands of years ago. Before that, the area was too flooded for settlement, making the temple's eventual rise even more remarkable. The ...

Not all microbes are villains--many are vital to keeping us healthy. Researchers have created a world-first database that tracks beneficial bacteria and natural compounds linked to immune strength, stress reduction, and resilience. The findings ...

Overfished coral reefs are producing far less food than they could. Researchers found that letting reef fish populations recover could boost sustainable fish yields by nearly 50%, creating millions of extra meals each year. Countries with high hunger ...

Scientists may have cracked the case of whether a seven-million-year-old fossil could walk upright. A new study found strong anatomical evidence that Sahelanthropus tchadensis was bipedal, including a ligament attachment seen only in human ancestors. ...
