New training programs will prepare astronauts to perform medicine while thousands of miles away from Earth
In the coming decade, more people will go to space than ever before as human spaceflight enters a new era. NASA, the European Space Agency and other governmental agencies are partnering to develop crewed missions beyond the moon. At the same time, th.....»»
How glacier algae are challenging the way we think about evolution
People often underestimate tiny beings. But microscopic algal cells not only evolved to thrive in one of the most extreme habitats on Earth—glaciers—but are also shaping them......»»
Earth"s atmosphere is our best defense against nearby supernovae, study suggests
Earth's protective atmosphere has sheltered life for billions of years, creating a haven where evolution produced complex lifeforms like us. The ozone layer plays a critical role in shielding the biosphere from deadly UV radiation. It blocks 99% of t.....»»
