Researchers have reconstructed ancient herpesvirus genomes from Iron Age and medieval Europeans, revealing that HHV-6 has been infecting humans for at least 2,500 years. Some people inherited the virus directly in their DNA, passing it down across .. ...

Scientists have created a new way to watch plants breathe--live and in high definition--while tracking exactly how much carbon and water they exchange with the air. The breakthrough could help unlock crops that grow smarter, stronger, and more ...

Scientists have discovered that wildfires release far more air-polluting gases than previously estimated. Many of these hidden emissions can transform into fine particles that are dangerous to breathe. The study shows wildfire pollution rivals human ...

Dogs began diversifying thousands of years earlier than previously believed, with clear differences in size and shape appearing over 11,000 years ago. A massive global analysis of ancient skulls shows that early dogs were already adapting to ...

Earthquakes happen daily, sometimes with devastating consequences, yet predicting them remains out of reach. What scientists can do is map the hidden layers beneath the surface that control how strongly the ground shakes. A new approach speeds up ...

Researchers discovered that a poison frog species described decades ago was based on a mix-up involving the wrong museum specimen. The frog tied to the official species name turned out to be brown, not the colorful animal shown in the original photo. ...

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 ...
