Popular sweeteners may leave effects that last for generations

Choosing the diet version of a favorite soda often means consuming non-nutritive sweeteners. These additives provide sweetness without the calories found in sugar. However, some health organizations have begun raising questions about their possible long-term effects, including whether they may disrupt energy metabolism and eventually contribute to a higher risk…

One injection could keep osteoarthritis drugs working for weeks

Scientists at the University at Buffalo have developed an injectable hydrogel designed to keep osteoarthritis treatments inside the joint for much longer than conventional injections. After a single minimally invasive injection, the material changes from a liquid into a smooth, lubricating semisolid depot at body temperature. Once in place, it…

Your waist size may reveal health risks BMI misses

A simple measurement around the waist could reveal important health risks that weight alone may miss, according to new research from Rutgers Health. The study, published in JAMA Network Open, found that measuring waist circumference, either by itself or together with body mass index (BMI), was about as effective as…

Scientists discover two superconducting states hiding as one

Uncovering this hidden structure could eventually allow researchers to design superconducting materials and devices with greater control and precision. As scientists pursue quantum computers, ultra-efficient electronics, and other advanced technologies, a detailed understanding of how electrons behave inside superconductors will become increasingly important. ng-standing puzzle about their behavior and offers…

A “quantum bath” puts quantum entanglement on autopilot

Future quantum computers may depend on the ability to connect widely separated modules through distributed entanglement. Until now, creating this kind of connection has generally required active control and repeated measurements. Physicists at the Institute of Science and Technology Austria (ISTA) have now demonstrated a fully autonomous alternative based on…

Scientists challenge a 70-year-old “lizard brain” myth

A long-standing picture of brain evolution as newer, rational layers stacked on top of an ancient “lizard brain” may be deeply misleading. Researchers found that evolution instead appears to balance two competing styles of brain wiring, expanding one while shrinking the other depending on what an animal needs to survive.…

Fossil feet may be misleading scientists about human evolution

New research suggests that whatever scientists ultimately discover about the last common ancestor of humans and chimpanzees, one characteristic may be difficult to dispute: it was probably capable of climbing trees. Humans and chimpanzees went their separate evolutionary ways between 6 and 7 million years ago, when they diverged from…

Scientists find why the liver may not heal even after you stop drinking

Excessive alcohol use can interfere with one of the liver’s most remarkable abilities: repairing and rebuilding itself after injury. New research suggests that alcohol related damage can leave liver cells trapped in an abnormal middle state, unable to function normally or complete the regeneration process, even after a person stops…

Carrello della spesa più caro del 29,5% in 5 anni – Notizie – Ansa.it

    Il carrello della spesa in Italia in cinque anni è cresciuto del 29,5%, un valore di molto superiore a quello dell’inflazione registrata nello stesso periodo (21%) con picchi per i prezzi degli ortaggi (+39% per quelli più usati in cucina), del caffè (+51%) e dell’olio extravergine (+47%). E’…

Rocky planets may have formed just 100 million years after the Big Bang

The ingredients needed to build rocky planets may have appeared as early as 100 million years after the Big Bang, according to new research from the University of Portsmouth. That would place the beginnings of planet formation remarkably close to the dawn of the Universe, even before the first galaxies…

Scientists discover diamonds can generate electricity

Researchers at the University of Hong Kong (HKU) have discovered that ultrathin, highly flexible diamond membranes can produce a measurable piezoelectric response, challenging a scientific assumption that has stood for more than a century. The work was led by Professor Zhiqin Chu, Associate Professor in the Department of Electrical and…
