Phys.org / Student astronomer discovers 'Rosetta Stone' for mysterious cosmic signals
An international team led by astronomers at the University of Sydney has uncovered the clearest evidence yet for the origin of an unusual class of cosmic signals. In doing so, they have identified a rare stellar system that ...
Medical Xpress / Unexpected chromosome interaction fuels aggressive cancers, researchers discover
Published in Nature, researchers at the University of Pittsburgh School of Medicine and UPMC Hillman Cancer Center report a previously unrecognized change in how the cell's genetic material is packaged into structures called ...
Medical Xpress / Women with kidney disease are undertested, undertreated and left behind by decades of male-dominated research
Women with chronic kidney disease are less likely than men to be diagnosed, represented in research and given treatments that have been properly tested in them. That is the central finding of a new paper published today in ...
Phys.org / First human SMUG1 atomic snapshots reveal how cells repair DNA
Researchers have captured the first atomic structures of human SMUG1, an enzyme that helps cells repair damaged DNA. The findings provide new insight into how cells recognize and remove harmful DNA bases, and may support ...
Tech Xplore / Ultra-thin semiconductors overcome performance limits with localized thick-contact design
As semiconductor chips become increasingly thinner, the components inside chips are locked in a fierce race to achieve the ultimate ultra-thin state. However, this has presented a structural limitation: the thinner the device, ...
Phys.org / Measuring massive surge waves along the Illgraben
Researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) have, for the first time, been able to record a debris flow over a distance of two kilometers at the Illgraben (VS). The study reveals ...
Medical Xpress / Basil and fennel compound may build up dangerous DNA damage in vulnerable people
Methyleugenol is a component of essential oils and is found in basil, tarragon, nutmeg, and fennel. When ingested through food, it can be converted in the liver into a reactive form that induces chemical alterations in DNA. ...
Medical Xpress / Study shows dangerous associations between drug and alcohol use and adolescent mental health

Medical Xpress / The hum that only a few can perceive: Potential sources of a low-frequency sound
Some people occasionally hear a low buzzing or humming sound that doesn't have a clear source. An estimated 2–4% of the world's population hear this. Scientists have been trying to figure out for decades where this sound ...
Phys.org / Q&A: Why do telomeres shorten when a cell divides, and how does it affect human aging?
In each cell of your body, DNA is stored in structures called chromosomes. When cells divide, these chromosomes are copied, but over time, the copying process degrades. After many cycles of making copies, the ends of the ...
Phys.org / Ancient altercations between musk turtles and alligator gar recorded in Florida's fossil record
Sometime between 5.5 and 5.6 million years ago, two shell crushers squared off in the languid currents of an ancient Florida river. The fossils they left behind, discovered by paleontologists at the Florida Museum of Natural ...
Medical Xpress / Why insulin, the core element of diabetes treatment remains inaccessible for millions of people
The discovery of insulin in 1921 revolutionized diabetes care. Type 1 diabetes went from being a death sentence to a manageable chronic condition.
