A key step in the origin of many pandemics occurs when an animal-borne virus infects humans and then evolves to spread more efficiently from person to person. That is why scientists and physicians keep a close watch on viruses ...
How did life make the leap from single cells to coordinated, multicellular organisms? And how do genetically identical cells still perform a version of that feat every time an embryo begins to take shape?
A team of Israeli scientists at the Hebrew University of Jerusalem has developed a novel method to significantly lower the production costs of cultivated meat. The new study demonstrates that preloading plant-derived cellulose ...
If plants had never learned to grow in multiple directions, our world would look very different. No trees, flowers, or other complex plants—and therefore no animals or humans. New research from the University of Copenhagen ...
Stanford scientists have discovered a new type of immune cell that kills surrounding cells via explosion—a cellular detonation so fast and complete that the cell vanishes within minutes, leaving no trace behind. This discovery ...
Spinal cord injuries can have devastating consequences for those affected. Nerve cells in the spinal cord rarely regenerate naturally, while scarring often prevents the regrowth of nerve fibers. Modern therapies attempt to ...
A team of researchers led by Luigi Naldini at the San Raffaele Telethon Institute for Gene Therapy (SR-Tiget) has developed a new strategy to significantly improve the precision and safety of CRISPR-Cas9 gene editing in human ...
Australian researchers have trained lab-grown brain cells on a silicon computer chip to play the nineties shooter game "Doom" and say they are just scratching the surface of what the neurons could be capable of doing.
Highlights from the last week of May, 2026: A key climate tipping point is disrupting the Arctic Ocean food chain (more of a lowlight, I guess). Scuba-diving tourism may not be the benefit to coral reef systems that we once ...
The current practice of freezing embryos—used to assist reproduction in humans or animals or to conserve endangered species—routinely causes ice to form within the cells, ripping through cell membranes, changing the way proteins ...
