A leaked scientific report jointly prepared by Israel's health ministry and Pfizer claims that the company's covid-19 vaccine is stopping nine out of 10 infections and the country could approach herd immunity by next month. The study, based on the health records of hundreds of thousands of Israelis, finds that the vaccine may sharply curtail transmission of the coronavirus. "High vaccine uptake c
After US president Joe Biden signed an executive order almost a month ago to move the United States toward rejoining the Paris climate agreement, the country formally reentered the international pact today, as Scientific American reports . The reentry signals the start of a lengthy process of drafting new emissions pledges. Biden called for an international climate summit on April 22, which falls
Jetpack Snapshot NASA has released a new photo sent to us all the way from Mars courtesy of its Perseverance rover, which successfully landed on the Red Planet on Thursday.

Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. The study also involved scientists from MIT, the universities of Hamburg, Cologne and Padua, and the Jülich Research Center. The results are important for the realization of quant
Duke researchers have been studying something that happens too slowly for our eyes to see. A team in biologist Philip Benfey's lab wanted to see how plant roots burrow into the soil. So they set up a camera on rice seeds sprouting in clear gel, taking a new picture every 15 minutes for several days after germination.

When the first black-hole collision was detected in 2015, it was a watershed moment in the history of astronomy. Using gravitational waves, astronomers were observing the universe in an entirely new way. But this first event didn't revolutionize our understanding of black holes—nor could it. This collision would be the first of many, astronomers knew, and only with that bounty would answers come.

And you don't have to believe in Murphy's Law to know that things don't always go according to plan. Emergency flashlights are great tools for those hard-to-foresee
Scientists have created new proteins that adopt one of the most complex folds known to molecular biology. These pore-like barrel-shaped proteins spontaneously fold into their intended structures and embed into lipid membranes. Although the scientists drew inspiration from proteins found throughout the living world, they arrived at sequences that differ from any known before. The resulting compact
Scientists uncover for the first time how the body's energy makers are made. An international team of researchers report an insight into the molecular mechanism of membrane-tethered protein synthesis in mitochondria. This is a fundamental new understanding of how the human mitoribosome functions and could explain how it is affected by mutations and deregulation leading to disorders like deafness a
A retrospective study conducted by LSU Health New Orleans reports that contrary to previous research, most patients who drop out of peritoneal dialysis may do so for psychosocial reasons. The findings are published in The American Journal of the Medical Sciences . The paper inspired a companion editorial.

BioNyt Videnskabens Verden (www.bionyt.dk) er Danmarks ældste populærvidenskabelige tidsskrift for naturvidenskab. Det er det eneste blad af sin art i Danmark, som er helliget international forskning inden for livsvidenskaberne.
Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.
Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
