Ritorno a scuola, aumentano mense, palestre e aule informatiche – Cronaca – Ansa.it

Più aule informatiche, più mense e più palestre nelle scuole italiane. Alla vigilia dell’avvio del nuovo anno scolastico, sul fronte degli spazi e dei servizi presenti nelle scuole arriva un segnale positivo: nell’ultimo quinquennio tutti e tre gli ambiti registrano una crescita costante. Le aule informatiche sono quasi raddoppiate, passando…

Your dislike of eating bugs may be 9,000 years old

As the global population grows and climate change places increasing pressure on food systems, researchers and policymakers are looking more closely at alternative sources of nutrition. Insects are one possible option. A total of 1,611 insect species are classified as edible, and organizations including the Food and Agriculture Organization of…

Eating more ultra-processed foods may raise prostate cancer risk by 30%

Ultra-processed foods (UPFs) now supply nearly 60% of the calories consumed by adults in the United States and about 70% of those consumed by children. These industrially produced foods include soft drinks, packaged cereals, snacks, and processed meats. They are typically made with refined fats, oils, sugars, starches, salts, and…

Vitamin C won’t prevent most colds, but it may do one small thing

From the first hint of cold winter mornings, supermarkets and pharmacies begin heavy marketing to coax us to stock up on vitamin C to get through the cold and flu season. But where did that idea come from? As we’ll see, it’s a story including a Nobel Prize winner, a…

A mysterious cosmic hum may come from 13-billion-year-old dark stars

A faint background of extremely low frequency gravitational waves detected through networks of pulsars could contain clues to events that unfolded more than 13 billion years ago, including the emergence of some of the Universe’s earliest supermassive black holes. In a study published as a Letter in Physical Review D,…

Scientists switch on a strange new form of magnetism in an ultrathin material

A recently proposed form of magnetism known as altermagnetism could eventually help researchers make computer memory smaller, faster, and more efficient. Now, scientists have found evidence that ruthenium dioxide, a quantum material previously considered nonmagnetic in its bulk form, may display this unusual magnetic behavior when prepared as an ultrathin…

324-million-year-old fossil reveals how insects conquered land

The rise of complex ecosystems on land was one of the major turning points in the history of life. As organisms expanded beyond the oceans, terrestrial environments became home to increasingly diverse communities. Insects, which today make up the most species-rich animal group on Earth, eventually became central to these…

Biscotti commestibili a partire dalla plastica delle bottiglie – Frontiere – Ansa.it

Trasformare la plastica delle bottiglie in materiali commestibili, come biscotti ricchi di proteine o vitamine: è l’obiettivo dello studio guidato da Lahiru Jayakody, dell’Università Southern Illinois, che in occasione del congresso autunnale della Società Americana di Chimica corso a Chicago ha presentato i primi successi in questa direzione con i…

Smart nanoparticles light up brain cancer and destroy what surgery misses

Glioblastoma is considered the most aggressive type of brain cancer. One reason it is so difficult to treat is that cancer cells spread into nearby brain tissue. That makes complete surgical removal extremely challenging because surgeons must avoid damaging healthy areas of the brain. The blood-brain barrier creates another obstacle…

Scientists discover a brain “brake” that can shut down chronic pain

Deep inside the brain, a small group of nerve cells helps control how strongly pain signals are felt. Under normal conditions, this system can suppress pain traveling through the spinal cord. After nerve damage, however, the same circuitry can become overactive and help sustain chronic pain. Researchers at Washington University…

Scientists may have finally caught “empty” space changing light

Nearly 90 years ago, Werner Heisenberg predicted a strange quantum effect known as vacuum birefringence, in which seemingly empty space can change the way light behaves. According to the idea, even a perfect vacuum is not truly empty. Instead, it should contain “virtual particles” that briefly appear and disappear. Despite…

NASA just used satellites and debris to navigate without GPS

NASA’s Starling mission has reached another milestone in autonomous spaceflight by demonstrating a system that can determine a satellite’s orbital position using other objects in space as reference points rather than depending on an external navigation network. The technology, called FALCON (Fast Autonomous Lost-in-space Catalog-based Optical Navigation), is designed to…

Addio a Tim Curry, leggendaria star del Rocky Horror Show – Cinema – Ansa.it

Tim Curry, l’attore britannico protagonista della parodia teatrale dei film dell’orrore The Rocky Horror Show e della relativa versione cinematografica, The Rocky Horror Picture Show, è morto ieri a Los Angeles a 80 anni. Non è stata resa nota immediatamente la causa della morte ma in passato – riporta Variety –…
