Melanoma rates are spiking fast in these 15 Pennsylvania counties

Counties in Pennsylvania that contain or sit close to cultivated cropland show notably higher melanoma rates than other parts of the state, according to new research led by scientists at Penn State. Researchers at the Penn State Cancer Institute reviewed cancer registry data collected from 2017 through 2021 and discovered…

AI creates the first 100-billion-star Milky Way simulation

Researchers led by Keiya Hirashima at the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan, working with partners from The University of Tokyo and Universitat de Barcelona in Spain, have created the first Milky Way simulation capable of tracking more than 100 billion individual stars across 10…

Microquasars emerge as the Milky Way’s most extreme particle engines

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have finally clarified a decades-old puzzle in astrophysics: the unusual drop in cosmic ray counts above 3 PeV that produces what scientists call the “knee” in the cosmic ray energy spectrum. The cause of this…

Extreme-pressure experiment reveals a strange new ice phase

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has captured the first-ever observation of water repeatedly freezing and melting at ultrahigh pressures above 2 gigapascals (2 GPa) while remaining at room temperature. These rapid changes were recorded on a microsecond (μs, one-millionth of a second)…

Scientists find a surprising link between lead and human evolution

A major international research effort is reshaping the long-held belief that lead exposure is primarily a modern problem. The new findings show that early human ancestors encountered lead repeatedly for more than two million years, suggesting that this toxic metal may have played an unexpected role in shaping the evolution…

Neuroscientists find immune cells that may slow aging

Prof. Alon Monsonego of Ben-Gurion University of the Negev found that T helper lymphocytes, which are immune cells involved in regulating the body’s defenses, shift in function as people grow older. These shifts can reflect a person’s biological age, which may not match their chronological age. Within these changes, the…

MotoGP: Bezzecchi vince il Gran Premio di Valencia – Notizie – Ansa.it

   Doppietta Aprilia a Valencia. Marco Bezzecchi ha vinto l’ultima gara del mondiale MotoGP davanti allo spagnolo Raul Fernandez. Terzo posto per la Ducati di Fabio Di Giannatonio.    Per Bezzecchi è la sesta vittoria in top-class, la terza di quest’anno, la seconda consecutiva dopo quella in Portogallo. Ai piedi…

Scontro violentissimo a Milano, un positivo alla droga e uno senza patente. Il Papa ricorda le vittime della strada: “Serve un esame di coscienza” – Notizie – Ansa.it

Il Papa all’Angelus ha ricordato “tutti coloro che sono morti in incidenti stradali causati troppo spesso da comportamenti irresponsabili. Ognuno faccia su questo un esame di coscienza”, ha chiesto il Pontefice. Uno degli autisti positivo al prestest droga e l’altro invece senza patente: sono questi i primi risultati delle indagini…

Dark matter acts surprisingly normal in a new cosmic test

Does dark matter behave according to the same physical rules that apply to ordinary matter? This question remains one of the major puzzles in modern cosmology, since this invisible form of matter (which neither emits nor reflects any light) is still hypothetical and extremely difficult to study directly. Researchers from…

Chimps shock scientists by changing their minds with new evidence

Chimpanzees may share more with human thinkers than researchers once realized. A new study published in Science presents compelling evidence that chimpanzees can revise their beliefs in a rational way when they encounter new information. The study, titled “Chimpanzees rationally revise their beliefs,” was carried out by an international team…

A single beam of light runs AI with supercomputer power

Tensor operations are a form of advanced mathematics that support many modern technologies, especially artificial intelligence. These operations go far beyond the simple calculations most people encounter. A helpful way to picture them is to imagine manipulating a Rubik’s cube in several dimensions at once by rotating, slicing, or rearranging…
