NASA celebrates America's 250th birthday with incredible views of space

NASA is marking the United States' 250th birthday with four striking red, white, and blue images of deep space from the Chandra X-ray Observatory. The collection features an exploded star, a stellar nursery, a galaxy where stars are rapidly forming, and a galaxy cluster that prov

Bumblebees exposed to up to 7 times as much toxic metal as honeybees

Bumblebees collect up to seven times the amount of toxic heavy metals as honeybees even when foraging in the same environment, new research from the University of Cambridge has found. Exposure to these metals can affect everything from their ability to forage for food to their ab

Citizen science could grow beyond data collection under 10 proposed recommendations

Citizen science is booming and could play a much greater role in tackling climate change, reef health, biodiversity and public health challenges by involving members of the public throughout the research process, according to a new study.

Cheetah chases inspire researchers to make a biologically accurate video game

Movement data from wild predator–prey encounters and controlled human catch-tag games have been combined to create realistic simulations of high-intensity movement dynamics and energetics—before being transformed into a publicly accessible video game. This game uses a citizen sci

Evidence of elusive high-energy gravitons in quantum Hall systems

Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a phenomenon that emerges when electrons are confined to a ve

Much of Earth's 'space dust' may come from unidentified near-Earth asteroids

Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way to obtain samples to study our cosmic neighbors. However,

Bumblebees collect up to 7 times more toxic metals than honeybees

Bumblebees are picking up dramatically more toxic heavy metals than honeybees, even when both species forage in the same places. Researchers warn that this hidden pollution could quietly reduce their ability to find food, reproduce, and keep colonies healthy.

The oldest deliberately collected fossil ichthyosaur was discovered in Roman Britain aroun

Around 1,800 years ago, a fossilized spinal bone lay on the windswept beaches of Roman Britain until a curious passerby picked it up and carried it far away, only to drop it in a pit.

The untapped potential of bowel cancer samples to boost understanding of other diseases

About half a million samples are collected from over-50s in Scotland each year in a highly successful NHS program that significantly boosts early cancer detection. But only a tiny amount of the sent-in poo—mixed with fluid—is needed to test for traces of blood, and the rest is di

Collective agreements are least common where workers need them most

Workers earning the lowest wages are the least likely to be covered by collective agreements in Germany, despite being the group for whom these protections are arguably most important. In 2021, only 34% of workers in the lowest wage decile were covered by collective agreements, c
