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…

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…

Scientists recover 40,000-year-old mammoth RNA still packed with clues

Researchers from Stockholm University have — for the first time ever — managed to successfully isolate and sequence RNA molecules from Ice Age woolly mammoths. These RNA sequences are the oldest ever recovered and come from mammoth tissue preserved in the Siberian permafrost for nearly 40,000 years. The study, published…

Extreme floods are slashing global rice yields faster than expected

Intense flooding has significantly reduced rice harvests around the world in recent decades, putting at risk the food supply of billions of people who rely on the grain as a dietary staple. Between 1980 and 2015, annual losses averaged about 4.3%, or roughly 18 million tons of rice each year,…

Smoking cannabis with tobacco may disrupt the brain’s “bliss molecule”

People who use both cannabis and tobacco show measurable differences in brain activity compared to those who rely solely on cannabis, according to new findings from a McGill University team at the Douglas Research Centre. These results may help clarify why people who combine the two substances more often experience…
