Scientists reverse Alzheimer’s in mice and restore memory

A study reveals that restoring the brain’s energy balance may not just slow Alzheimer’s — but actually reverse it. For more than a century, Alzheimer’s disease has been widely viewed as permanent and untreatable once it begins. As a result, most research has focused on preventing the disease or slowing…

What you eat could decide the planet’s future

eople, the holidays often bring joyful indulgence, followed by regret and ambitious New Year’s resolutions to eat better. A recent study from the University of British Columbia suggests moderation should not be a seasonal goal but a long-term one. The research found that 44 percent of the global population would…

Why consciousness can’t be reduced to code

Today’s arguments about consciousness often get stuck between two firm camps. One is computational functionalism, which says thinking can be fully described as abstract information processing. If a system has the right functional organization (regardless of the material it runs on), it should produce consciousness. The other is biological naturalism,…

AI supercharges scientific output while quality slips

After ChatGPT became widely available in late 2022, many researchers started telling colleagues they could get more done with these new artificial intelligence tools. At the same time, journal editors reported a surge of smoothly written submissions that did not seem to add much scientific value. A new Cornell study…

A Natale neve in montagna, vento e piogge battenti in pianura – Notizie – Ansa.it

Sarà un Bianco Natale in montagna con abbondanti nevicate sopra i 600-700 metri al Nord e sull’Appennino Tosco-Emiliano, oltre i 1000-1200 metri sul resto della dorsale. Sul resto dell’Italia sono previsti vento e piogge battenti. Ma per l’ultimo weekend dell’anno torna il sole. È quanto conferma Lorenzo Tedici, meteorologo responsabile…

We are living in a golden age of species discovery

Roughly three centuries ago, Swedish naturalist Carl Linnaeus set out to catalog and name every living organism he could find. He is now widely regarded as the founder of modern taxonomy after introducing the binomial naming system and formally describing more than 10,000 species of plants and animals. Scientists have…

Scientists say evolution works differently than we thought

For decades, many evolutionary biologists have believed that most genetic changes shaping genes and proteins are neutral. Under this view, mutations are usually neither helpful nor harmful, allowing them to spread quietly without being strongly favored or rejected by natural selection. A new study from the University of Michigan challenges…

This new 3D chip could break AI’s biggest bottleneck

Engineers from Stanford University, Carnegie Mellon University, University of Pennsylvania, and the Massachusetts Institute of Technology worked with SkyWater Technology, the largest exclusively U.S. based pure play semiconductor foundry, to create a new multilayer computer chip. The team says its architecture could mark a major shift in AI hardware and…

This tiny peptide could help stop brain damage after injury

A global research team led by the company Aivocode, working with scientists from the Institute for Advanced Chemistry of Catalonia (IQAC) of the Spanish National Research Council (CSIC), reports that a small compound has a strong protective effect in mouse models of traumatic brain injury. The compound is a peptide…

These nanoparticles kill cancer cells while sparing healthy ones

Researchers led by RMIT University have developed extremely small particles called nanodots that can destroy cancer cells while largely leaving healthy cells unharmed. The particles are made from a metal-based compound and represent a possible new direction for cancer treatment research. The work is still in its early stages and…

Your roommate’s genes may be shaping your gut bacteria

The genes of your roommate may be shaping the bacteria in your gut, and your genes may be influencing theirs, according to a rat study published on December 18 in Nature Communications. By examining more than four thousand rats, researchers found that the makeup of the gut microbiome is affected…
