Scientists once thought of dinosaurs as sluggish, cold-blooded creatures. Then research suggested that some could control their body temperature, but when and how that shift came about remained a mystery.
Scientists have discovered a long-buried branch of the Nile river that once flowed alongside more than 30 pyramids in Egypt, potentially solving the mystery of how ancient Egyptians transported the massive stone blocks to build the famous monuments.
The way we make decisions in a social context can be explained by psychological, social, and political factors. But what if other forces were at work? Hilke Plassmann and her colleagues from the Paris Brain Institute and the University of Bonn show that changes in gut
This week, we reported on the birth throes of black holes, the questionable assertions of a study about vegan dogs and a technique for observing entanglement without breaking quantum coherence.
Strong field quantum optics is a rapidly emerging research topic, which merges elements of non-linear photoemission rooted in strong field physics with the well-established realm of quantum optics. While the distribution of light particles (i.e., photons) has been widely
Researchers have discovered hundreds of historical accounts of humans hunting prey by chasing them down over long distances, which some believe is why we evolved our unique talent for endurance running.
Our family dog used to have a rather noticeable extra eyelid that became especially apparent when he dozed off, usually upturned on the rug. This is the fleshy curtain seen at the corner of each eye, closest to the nose. It's also commonly called the nictitating (literally
The massive coral bleaching episode signaled by US authorities last month is expanding and deepening in reefs around the globe, scientists warned Thursday.
In a May 15 paper released in the journal Physical Review Letters, Virginia Tech physicists revealed a microscopic phenomenon that could greatly improve the performance of soft devices, such as agile flexible robots or microscopic capsules for drug delivery.
Tourists normally have to pay big money and brave cold climates for a chance to see an aurora, but last weekend many people around the world simply had to look up to see these colorful displays dance across the sky.
A lack of detailed record-keeping in clinics and emergency departments may be getting in the way of reducing the inappropriate use of antibiotics, a pair of new studies suggests. In one of the studies, about 10% of children and 35% of adults who got an antibiotic prescription
The latest findings forecast that global life expectancy will increase by 4.9 years in males and 4.2 years in females between 2022 and 2050. Increases are expected to be largest in countries where life expectancy is lower, contributing to a convergence of increased life
Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the biochemical machinery that builds lignin, a structural component of plant cell walls
A recombinant form of human ADAMTS13 approved for a different condition helped to save the life of a young mother with immune thrombotic thrombocytopenic purpura.
A study has found that repeat vaccination with updated versions of the COVID-19 vaccine promotes the development of antibodies that neutralize a wide range of variants of the virus that causes COVID-19, as well as related coronaviruses.
The sweet-taste receptor might be the first stop in a metabolic surveillance system for sugar. The receptor is also expressed in certain intestinal cells, where it may facilitate glucose absorption and assimilation, as part of this system. A team found that stimulation and
The basis of the marine food web in the Arctic, the phytoplankton, responds to heatwaves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic. The phytoplankton's behavior primarily depends on the cooling
In mice, a ketogenic diet increases the build-up of zombie-like cells in the heart, kidney, lungs and brain, which can accelerate organ ageing and lead to health problems
