Newly discovered coffee compounds beat diabetes drug in lab tests

Three newly identified compounds were found to strongly inhibit α-glucosidase, an enzyme that plays a central role in breaking down carbohydrates during digestion. Because this enzyme directly affects how quickly sugars enter the bloodstream, the discovery points to possible new functional food ingredients aimed at managing type 2 diabetes. Functional…

A new theory of gravity could explain cosmic acceleration without dark energy

Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot fully explain this accelerating growth. Today’s standard picture of the universe is built on Einstein’s general theory of relativity and the standard model of particle physics. Within this framework, scientists…

Injection turns sleeping tumor immune cells into cancer fighters

Tumors in the human body contain immune cells called macrophages that are naturally capable of attacking cancer. However, the tumor environment suppresses these cells, preventing them from doing their job. Researchers at KAIST have now found a way to overcome this barrier by directly transforming immune cells already inside tumors…

“Piani di Israele per una nuova offensiva a Gaza a marzo” – Notizie – Ansa.it

L’esercito israeliano “ha elaborato piani per lanciare nuove massicce operazioni militari intensive a Gaza a marzo”, con un’offensiva mirata a Gaza City volta a spingere la linea gialla di demarcazione del cessate il fuoco verso la costa dell’enclave, espandendo ulteriormente il controllo sul territorio. Lo scrive il Times of Israel,…

A room full of flu patients and no one got sick

This year’s flu season has been especially harsh, driven in part by the rapid spread of a new variant known as subclade K. As cases rise, a newly released study offers surprising insight into how influenza spreads and how people may better protect themselves from getting sick. To better understand…

Notte di proteste in Iran, prosegue il blackout di internet. Israele in massima allerta per la possibilità di un intervento degli Stati Uniti a Teheran – Notizie – Ansa.it

Nella notte di sabato, gli slogan antigovernativi hanno riempito le strade della capitale iraniana Teheran, mentre i manifestanti incitavano al più grande movimento contro la repubblica islamica degli ultimi tre anni, nonostante una repressione forte sotto la copertura di un blackout di Internet, secondo quanto riporta Afp. L’Iran ha attribuito…

This wild fruit is getting a CRISPR makeover

For roughly 10,000 years, farming communities have improved their crops by saving seeds from plants with the best flavor, size, and toughness. This slow and careful process shaped nearly every fruit and vegetable found in grocery stores today. Most modern crops are the result of centuries or even millennia of…

When the oceans died and life changed forever

Around 445 million years ago, Earth underwent a dramatic transformation that reshaped the future of life. In a remarkably short geological period, massive glaciers spread across the southern supercontinent Gondwana. As ice locked up water, vast shallow seas dried out, triggering an “icehouse climate” and radically altering ocean chemistry. The…

A never-before-seen creature has been found in the Great Salt Lake

Scientists studying the Great Salt Lake have identified at least one species of nematode that is completely new to science, with evidence suggesting there may be a second. Researchers from the University of Utah recently published a paper describing the tiny roundworm and formally naming it in a way that…

A daily fish oil supplement slashed serious heart risks in dialysis patients

A large international study has found that taking a daily fish oil supplement can sharply lower the risk of serious heart-related complications in people undergoing dialysis for kidney failure. The research was co-led in Australia by Monash Health and the School of Clinical Sciences at Monash University. The study, known…

This new imaging technology breaks the rules of optics

Imaging tools have dramatically reshaped how scientists study the world, from charting faraway galaxies with radio telescope networks to revealing intricate structures inside living cells. Even with decades of progress, one major obstacle has remained. At optical wavelengths, it has been extremely difficult to capture images that are both highly…
