La parola della settimana: fine – La parola della settimana – Ansa.it

ANSA – di Massimo Sebastiani. Né cachistocrazia né longevo: la parola della settimana è fine, visto che (per fortuna) in un modo o in un altro si torna a parlare di fine-vita. Una parola dall’area semantica estesa, come dicono i linguistici, che ha tre o quattro significati ma in cui…

Indonesia’s most dangerous fires are burning underground

Tropical peatland fires rank among the most dangerous and stubborn fires on Earth. Instead of racing through trees and vegetation, these fires smolder through dried wetland soils and large deposits of peat, often continuing underground at relatively low temperatures. That makes them extremely difficult to extinguish and exceptionally polluting. By…

AI can now control fusion plasma faster than humans can react

In some fusion systems, particles hotter than the core of the sun can become unstable within just a few thousandths of a second. That is far too fast for a human operator to respond. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University…

Scientists find a weak spot in one of the deadliest brain cancers

Researchers may have found a new way to weaken glioblastoma’s defenses against treatment. Blocking a protein called SET prevented tumors from forming in preclinical models, while targeting related proteins made cancer cells more vulnerable to radiation. The strategy works by restoring activity of PP2A, an enzyme that glioblastoma cells appear…

A mysterious signal around Earth could be dark matter

Dark matter is one of the biggest unsolved mysteries in modern physics. Astronomers are highly confident that it exists and estimate that it accounts for about a quarter of the universe’s total energy content, yet scientists still do not know what it is made of. Two leading possibilities are hypothetical…

80,000-year-old “arrowheads” rewrite human history

Unretouched triangular microlithic projectile points have been identified from their impact traces in the oldest occupation layers of the Obi-Rakhmat site in Uzbekistan, dating to 80,000 years ago. Their size corresponds to small arrowheads, which are directly comparable to those produced by Homo sapiens during an incursion into Neanderthal territory…

Heart disease and kidney disease can fuel each other. New guidelines aim to break the cycle

The European Society of Cardiology has issued its first guidelines dedicated to managing cardiovascular disease alongside chronic kidney disease, developed in partnership with the European Renal Association. The recommendations were published in the European Heart Journal and presented at ESC Congress 2026. Chronic kidney disease (CKD) is diagnosed when abnormalities…

This “new” frog was hiding in plain sight for 100 years

Scientists at the Pontificia Universidad Católica del Ecuador have formally described Pristimantis milpe, a common and widespread frog that spent more than a century being mistaken for another species. The mystery was resolved by studying specimens collected in Ecuador during the 19th century and preserved at the Natural History Museum…

Some joints may be primed for rheumatoid arthritis before birth

Researchers at the Kennedy Institute have found evidence that some joints may be more vulnerable to inflammatory arthritis before birth. The discovery could help explain a long-standing puzzle in rheumatoid arthritis: why the disease repeatedly attacks certain joints while leaving others largely untouched. The study, “The embryonic origins of site-specific…

Compound in blueberries may help muscle cells burn excess fat

Excess fat stored inside skeletal muscle has become an important metabolic health concern. This type of fat buildup can be encouraged by high-fat diets, physical inactivity, and aging. Unlike fat stored under the skin, lipid droplets that accumulate within muscle cells can interfere with normal muscle function and make it…
