Miniature livers will fly aboard the International Space Station in an upcoming study on whether microgravity can encourage the growth of healthy tissue with an ample blood supply. It’s an effort that could potentially lead to personalized, space-grown tissues and organs for use in transplant surgeries, scientists say. In two upcoming experiments, researchers plan to … Read more
Tiny photosynthetic microbes could be secretly thriving on Mars — hiding inside small bubbles of liquid water in the thin layers of dusty ice that litter the Red Planet’s surface, a new NASA-led study reveals. Researchers believe the icy patches could be among the most promising targets in the hunt for extraterrestrial life within our … Read more
Imagine you are in a soccer match, and it’s tied. Each team will begin taking penalty kicks. The crowd is roaring, and whether or not your team wins the game depends on your ability to hit the shot. As you imagine this scene, are you able to picture the scenario with colors and details? Scientists … Read more
Plants can grow with much less light than previously thought, according to a new study on tiny water-based organisms called microalgae that has been published in Nature Communications. The German-led team of researchers lowered light sensors into Arctic water to a depth of 164 feet (50 metres) to test how low light levels must become … Read more
Scientists have revived a mysterious, 1,000-year-old seed discovered in the Judaean Desert — and the tree that has grown from it could belong to a lost lineage mentioned in the Bible, they say. It has taken researchers almost 14 years to grow a tree from the ancient seed, which archaeologists excavated from a cave in … Read more
Robots smaller than most bacteria could deliver drugs right to the site of a brain aneurysm, preventing a devastating stroke, a new animal study suggests. The new technology has been tested only in rabbits so far. But with further study, it could become an alternative to the stents and coils that are currently used to … Read more
There are more than 70 species of salps worldwide, with Salpa fusiformis being the most common. Salps can be found from the ocean surface down to around 2,600 feet (800 meters) deep. They are barrel shaped, ranging from 0.08 inches (0.2 centimeters) at birth to about 4 inches (10 cm) in adulthood. They can join … Read more
Memories evolve throughout our lifetimes, changing as we learn and experience new things and as we recall a memory repeatedly. And then, memories degrade as we age. Previously, scientists thought that this malleability was the result of changes in the brain cells that originally encoded the memory, and they believed these cells stored just one … Read more
Researchers have made a breakthrough in the race to save the world’s bananas from a devastating disease that could wipe them out, according to a new study. The bananas we eat, called Cavendish bananas, are threatened by a plant-killing disease called fusarium wilt. This disease has already wiped out other banana varieties, and it devastated … Read more
The human body does not age at a constant rate throughout adulthood — instead, it accelerates dramatically around ages 44 and 60, a new study finds. The new research, published Aug. 14 in the journal Nature Aging,involved measuring more than 11,000 molecules in the adult body over time, and it revealed that 81% of them … Read more
