Using data from both mice and humans, a research team has found that a cell surface protein that senses odors and chemicals may be responsible for -- and help explain -- male/female differences in mammalian blood pressure. Read more ›

Measuring between 3 to 3.5 meters, 16 million years old: Paleontologists have announced the discovery of a new species of freshwater dolphin in the Peruvian Amazon region. Surprisingly, its closest living relatives can be found in the river dolphins of South Asia. Read more ›

The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your veins and the calcium in your teeth and the sodium powering your thoughts were all born in the heart of a long-dead star. Read more ›

Working in the Horn of Africa, researchers have uncovered evidence showing how early modern humans survived in the wake of the eruption of Toba, one of the largest supervolcanoes in history, some 74,000 years ago. Modern humans dispersed from Africa multiple times, but the event that led to global expansion occurred less than 100,000 years ago. Some researchers hypothesize that dispersals were restricted to 'green corridors' formed during humid intervals... Read more ›

Scientists have created a giant quantum vortex to mimic a black hole in superfluid helium that has allowed them to see in greater detail how analogue black holes behave and interact with their surroundings. Read more ›

If it walks like a particle, and talks like a particle... it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. Researchers now demonstrate the atypical behavior of topological solitons in a robotic... Read more ›

When small hierarchical groups bond, neural activity between leaders and followers aligns, promoting quicker and more frequent communication, according to a new study. Read more ›

Researchers showed in 2022 that heat index calculations by NOAA based on analyses from the 1970s don't adequately reflect the heat stress humans feel during the extremes of heat and humidity accompanying climate change. Using their revised heat index, the researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees...

Men and women with lower income or education levels are more likely to develop medical conditions related to alcohol abuse compared to similar individuals with a higher socioeconomic status, according to a new study. Read more ›

A new study has shown that food-seeking cells exist in a part of a mouse's brain usually associated with panic -- but not with feeding. Activating a selective cluster of these cells kicked mice into 'hot pursuit' of live and non-prey food, and showed a craving for fatty foods intense enough that the mice endured foot shocks to get them, something full mice normally would not do. If true in... Read more ›

A new study has identified recurring, 'toxic' human conversation patterns on social media, which are common to users irrespective of the platform used, the topic of discussion, and the decade in which the conversation took place. Read more ›

A study of over 20,000 adults found that those who followed an 8-hour time-restricted eating schedule, a type of intermittent fasting, had a 91% higher risk of death from cardiovascular disease. Read more ›

Leafhoppers, a common backyard insect, secrete and coat themselves in tiny mysterious particles that could provide both the inspiration and the instructions for next-generation technology, according to a new study. In a first, the team precisely replicated the complex geometry of these particles, called brochosomes, and elucidated a better understanding of how they absorb both visible and ultraviolet light.

Dinosaurs get all the glory. But aetosaurs, a heavily armored cousin of modern crocodiles, ruled the world before dinosaurs did. These tanks of the Triassic came in a variety of shapes and sizes before going extinct around 200 million years ago. Today, their fossils are found on every continent except Antarctica and Australia.

When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world. Some scientists are also looking at something a little more tangible: coral. Read more ›

Performing a new task based solely on verbal or written instructions, and then describing it to others so that they can reproduce it, is a cornerstone of human communication that still resists artificial intelligence (AI). A team has succeeded in modelling an artificial neural network capable of this cognitive prowess. After learning and performing a series of basic tasks, this AI was able to provide a linguistic description of them... Read more ›
