Hospital workers' phones carry deadly superbugs
The largest study of its kind has found hospital workers' phones are carrying the same superbugs that kill millions of people worldwide each year. An international team of researchers, including several from Bond University, analyzed DNA samples from 95 mobile phones belonging to
Do hyenas eat livestock and rhinos? Behavioral biologists investigate a surprisingly charm
For conservation and the management of human–wildlife conflicts, it is of great interest to know which species are eaten by carnivores. Scientists from the Ngorongoro Hyena Project at the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) analyzed this dynamic for spot
FDA-approved drug may finally help immunotherapy defeat rare liver cancer
Researchers found that a rare liver cancer evades immunotherapy by luring immune T cells away from the tumor and trapping them in nearby fibrous tissue. An FDA-approved drug called AMD3100 freed those T cells to attack the cancer, significantly improving the effectiveness of immu
Hidden for decades, hospital superbug built resistance in waves, peaking in the mid‑2000s
Hidden for decades, hospital superbug built resistance in waves, peaking in the mid‑2000s
Decades-old hospital samples have helped University of East Anglia (UEA) researchers uncover how a deadly antibiotic-resistant "superbug" quietly tightened its grip across the globe. It lurked in hospital corridors for decades, largely unnoticed by the wider public.
Beachcomber's find fuels whale study breakthrough
During his morning runs, Rod Keogh had no doubt that the whale poo he saw washed up on the beach had value. Science has finally caught up with him. Samples collected by the South Australian man have contributed to a groundbreaking study of the diets and microbiomes of southern ri

China's space probe reaches asteroid after 1-billion-kilometer chase for first sample retu
China's Tianwen-2 space probe, which is set to bring back samples from an asteroid for research, has reached its target after traveling 1 billion kilometers (620 million miles) over more than a year, the Chinese space agency said Monday.
Traces of Earth's primordial magma ocean discovered in lava from a modern volcanic eruptio
In May 2018, the island of Mayotte, between Madagascar and Mozambique, began to experience a series of earthquakes that led to the discovery of an underwater volcano, now called Fani Maoré. Multiple scientific expeditions followed, taking samples of the recently erupted lava. Whe
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,
From the lab to the moon: Lunar cement alternative survives 6 months on ISS and returned s
Building material samples from the University of Delaware spent six months mounted outside the International Space Station, where the harsh conditions of low Earth orbit tested their limits.
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
