Researchers have found a way to reduce guesswork and errors in genetic engineering by eliminating unwanted or 'junk' genes from plant chromosomes. This new method allows for targeted gene insertion and excision, enabling more precise control over genetic transformations.
Researchers found that nitric oxide synthase is activated within minutes after nerve cell damage in medicinal leeches, leading to regeneration. The study suggests NOS may aid in minimizing tissue damage and infection by flagging down microglia at the site of injury.
Researchers have identified mobile DNA segments in the maize genome that are similar to retroviruses, which could provide a mechanism for plants to resist certain viruses. These 'selfish DNAs' can replicate and transmit to future generations without harming their hosts.
A team of astronomers observed extremely rapid bursts of high-energy gamma rays from a distant galaxy, challenging current theoretical models. The bursts were extremely rapid, occurring in under half an hour, while previous flares occurred over days or minutes.
Researchers at Purdue University have developed an ultrathin film made from gold atoms that conducts electricity by allowing electrons to 'hop' one at a time. This new material, called linked cluster network, could lead to the development of more powerful computers and miniaturized electrical devices.
