[ad_1] In the images of the Hubble Space Telescope, scientists have identified a completely new phenomenon. Reaching tens of thousands of light-years into the vacuum of space, vast shadows extend from the center of the galaxy IC 5063, as if something was blocking the bright light from there. You’ve probably …

[ad_1] Leonardo da Vinci was one of the greatest geniuses in history, with skills and inventions far ahead of his time. On many occasions his work has been shrouded in mystery, hiding secrets not visible at first sight. Now, a new study has found another, linked to bacteria and fungi. …

[ad_1] Bee biodiversity usually flies under the radar. There are 20,000 bee species out there, spread across a wide range of habitats and climates. The researchers have now compiled the most detailed global map of bees that could be invaluable for conservation efforts. Image credits: Boris Smokrovic. Bees are in …

[ad_1] According to the researchers, scientists successfully reversed the human aging process: oxygen treatment altered the body of older people at the cellular level Breathing pure oxygen can help reverse the aging process, scientists say Researchers used oxygen therapy to reverse two key indicators of aging Scientists placed 35 healthy …
