Scientists have uncovered microbial DNA preserved in mammoth remains dating back more than one million years, revealing the oldest host-associated microbial DNA ever recovered. By sequencing nearly 500 specimens, the team identified ancient bacterial ...

New research reveals that carbon made it possible for Earth's molten core to freeze into a solid heart, stabilizing the magnetic field that protects our planet. Without it, Earth's deep interior -- and life above -- might look very different.

Scientists uncovered a 310-million-year-old fish fossil with a "tongue bite," teeth on the roof and floor of its mouth that worked like a second jaw. This adaptation, previously thought to have appeared much later, shows how fish rapidly experimented ...

A Japanese research team successfully harnessed E. coli to produce PDCA, a strong, biodegradable plastic alternative. Their method avoids toxic byproducts and achieves record production levels, overcoming key roadblocks with creative fixes.

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing likely shaped its evolutionary emergence.

Past climate assessments let big polluters delay action, placing more burden on smaller nations. A new method based on historical responsibility demands steep cuts from wealthy countries and more financial support for poorer ones. Courts are now ...

Scientists at Northwestern University have developed a groundbreaking nickel-based catalyst that could transform the way the world recycles plastic. Instead of requiring tedious sorting, the catalyst selectively breaks down stubborn polyolefin ...

Snowfall shortages are now destabilizing some of the world's last resilient glaciers, as shown by a new study in Tajikistan's Pamir Mountains. Using a monitoring station on Kyzylsu Glacier, researchers discovered that stability ended around 2018, ...

Fossilized bones in Brazil reveal that deadly infections plagued sauropods 80 million years ago. Researchers uncovered unhealed lesions consistent with osteomyelitis, pointing to pathogens spread through stagnant waters or insect bites.

A new study projects that the Atlantic Meridional Overturning Circulation (AMOC)--the system of currents that includes the Gulf Stream--could shut down after 2100 under high-emission scenarios. This shutdown would drastically reduce heat transport .. ...
