E. coli is arguably the most well-studied organism on Earth, but scientists have now discovered a new behavior that’s almost never seen in bacteria. The normally single-celled organisms have shown signs of previously unknown multicellular phases.Contin… Continue reading Single-celled bacteria exhibit previously unknown “multicellularity”
Nerve damage can result in pain that lasts for years, or even a lifetime. There may be new hope, however, as scientists now report that exposing damaged nerves to a cold needle can cause them to regenerate, drastically reducing pain.Continue ReadingCat… Continue reading Cold needle treatment may reduce pain by regenerating damaged nerves
The world has surpassed over 500 million officially recorded COVID-19 cases, according to data from Johns Hopkins University. This grim milestone is almost certainly an undercount, with some researchers estimating nearly half of the world’s total popul… Continue reading World hits 500 million official COVID cases but real tally likely billions
Researchers at Harvard and Emory University have created a biohybrid fish out of human heart muscle cells that can swim autonomously for months at a time as the cells beat. The project is a quirky sidestep on the way to eventually growing new functioni… Continue reading Biohybrid fish powered by beating human heart cells swims for 100 days
Although a technology known as electroporation is very effective at delivering DNA-based vaccines, the required equipment tends to be bulky, complex and expensive. Now, however, scientists have shown that a converted barbecue lighter is capable of doin… Continue reading More-effective vaccination tech is built around a barbecue lighter
Viruses largely get a bad rap, but some may be helpful. Oncolytic viruses selectively hunt down and kill cancer cells, but this emerging therapy can be rendered ineffective or even dangerous if it alerts the immune system. Now scientists have tweaked t… Continue reading Modified cancer-killing virus avoids triggering immune system response
Injections of pain-relief medication into the affected joints is one of the primary ways physicians treat discomfort in sufferers of osteoarthritis, but the effects don’t last forever. A novel technique that involves directing low-grade radiofrequency … Continue reading Stunning nerves with radio waves offers relief from arthritic pain
