Scientists open a million-year-old time capsule hidden beneath New Zealand

A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō. The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long

Scientists just discovered how queen bees are really made

For decades, scientists thought royal jelly was the secret ingredient that turned an ordinary honeybee larva into a queen. New research reveals the process is far more remarkable: young worker bees create special “royal cribs” made from customized wax, carefully regulate warmth a

Scientists alarmed after two wildfires hit Greenland within a week

Researchers say it is ‘quite wild’ to see fires at such high northern latitudes happen so early in the yearScientists have expressed concern after two wildfires broke out within a week of each other on the Arctic island of Greenland earlier this month.Fires were burning close to

Scientists create optical skyrmions using a two-century-old light phenomenon

Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, which are tiny, swirling configurations in the properties of light—akin to the spik

Hidden bird species discovered in Japan after DNA reveals a stunning secret

A bird long thought to be a single rare species in Japan has turned out to be two. Scientists discovered that the elusive Ijima’s Leaf Warbler and a newly identified Tokara Leaf Warbler look almost identical, but their DNA and songs reveal they are distinct species. The finding m

The tea in your kombucha changes more than just the taste

Scientists discovered that kombucha’s flavor, chemistry, and antioxidant activity vary dramatically depending on the tea used to make it. Green and oolong tea kombuchas emerged as the most biologically active, while fermentation transformed each tea into a distinctly different be

A rare interstellar visitor triggered a SETI search for alien technology

SETI scientists searched the interstellar object 3I/ATLAS for radio signals that could indicate extraterrestrial technology but found nothing beyond human-made interference. Even so, the rapid-response observations helped confirm the object's natural origin and showcased how futu

The Guardian view on extreme heat: as risks escalate, adaptation plans are dangerously lag

Record-breaking temperatures should focus minds on the UK’s lack of preparedness for the climate dangers aheadAs western Europe bakes under what scientists describe as a heat dome, or “atmospheric lid”, reports of dozens of drownings, and heat-linked deaths of children and elderl

Controlling ice crystal growth using polymer nanoparticles

Ice formation can damage biological samples, tissues and materials during freezing and thawing. In nature, specialized molecules known as ice-binding proteins prevent ice crystals from growing too large, helping organisms survive in extreme cold. Scientists have long tried to rep

Discovery of how cells maintain their DNA could shield key healthy cells from chemotherapy

A new study conducted by scientists at the University of Sheffield in collaboration with researchers from UT Southwestern Medical Center in the U.S. has found a protein that could help guide which cells chemotherapies target. The findings, published in Molecular Cell, open up a p
