What does the first successful test of a pig-to-human kidney transplant mean?
The milestone is a step toward solving shortages of the organ but hurdles remain. Surgeons in New York City successfully attached a pig kidney to a human patient and watched the pinkish organ function normally for 54 hours. While such procedures have been done in nonhuman primates, this is the first time that a pig kidney has been transplanted to a human body and not been immediately rejected.
International Scientific and Practical Conference «DECARBONIZATION IN THE EUROPEAN UNION AND NEW PARADIGM FOR THE DEVELOPMENT OF FUEL & ENERGY COMPLEX IN RUSSIA» will take place in Kazan August 31 – September 1, 2021.
The coronavirus’s delta variant is different from earlier strains of the virus in worrying ways, health officials are discovering. And those differences may mean a return to some of the restrictions that vaccinated people thought were in the past.
Machine-learning systems from the company and from a rival academic group are now open source and freely accessible.
It’s protein-structure prediction for the people. Software that accurately determines the 3D shape of proteins is set to become widely available to scientists.
For some dinosaurs, the Arctic may have been a great place to raise a family
Fossil baby teeth and bones hint that some dinosaurs reared their young near the North Pole.
Dinosaurs didn’t just summer in the high Arctic; they may have lived there year-round, new fossil evidence suggests.
Mysterious fast radio bursts come in two distinct flavours
A trove of new detections suggests that the bursts could be the result of at least two separate astrophysical phenomena.
A radio telescope in Canada has detected 535 fast radio bursts, quadrupling the known tally of these brief, highly energetic phenomena in one go. The long-awaited results show that these enigmatic events come in two distinct types — most bursts are one-off events, with a minority repeating periodically and lasting at least ten times longer on average.
That core isn’t the lump of rock and ice that many scientists had envisioned, the new study finds. Instead, the core is diffuse, pervaded by huge amounts of hydrogen and helium and so spread out that it spans 70,000 kilometers, or about 60 percent of the planet’s diameter, researchers report April 28 at arXiv.org.
A ‘blue bang’ sparks an unusual type of lightning in the upper atmospher. The International Space Station spotted an exotic type of upside-down lightning called a blue jet (illustrated) zipping up from a thundercloud into the stratosphere in 2019.
