Peatland conservation may prevent new diseases from jumping to humans

Peatland conservation may prevent new diseases from jumping to humans

Science
Nov. 17 (UPI) -- In a new paper, scientists argue tropical peatland areas have been mostly ignored as potential settings for new diseases to jump from animals to humans. According to the authors of the new study, published Tuesday in journal PeerJ, better protecting and restoring tropical peat-swamp forests could help curb the effects of the current pandemic, and also prevent the emergence of future zoonotic diseases. Advertisement COVID-19 has changed the way we look at the world -- and scientists say it's also changed the way they look at their areas of expertise. "As it became increasingly clear that COVID-19 wasn't going to magically disappear in a few weeks, we began thinking and talking about what the potential impacts of the pandemic might be on the conservation of this ecosystem a...

NASA certifies SpaceX to carry humans, OKs space station mission

Science
ORLANDO, Fla., Nov. 10 (UPI) -- NASA certified SpaceX's spaceflight system Tuesday to carry astronauts to the International Space Station regularly, clearing the way for a four-person mission there planned for Saturday. Elon Musk's company plans to launch its Crew Dragon capsule, which its four passengers have called Resilience, aloft atop a Falcon 9 rocket from Kennedy Space Center in Florida. Advertisement This will mark the first time in the history of spaceflight that four people traveled into space in one capsule. The space shuttles typically carried seven-member crews. "We are honored to be the nation's launch provider for crewed missions and take seriously the responsibility that NASA has entrusted to us to carry American astronauts to and from the space station," Benji Reed, Space...

Orion spacecraft ready to return humans to deep space, officials say

Orion spacecraft ready to return humans to deep space, officials say

Science
ORLANDO, Fla., Oct. 16 (UPI) -- The anticipated return to deep space in 2024 for the first time in nearly 50 years brings a unique set of challenges that only one spacecraft on the planet currently can meet, officials with Lockheed Martin said at a global space event this week. Life support and radiation shielding systems on NASA's Orion spacecraft, built by Lockheed, make it qualified for deep space missions -- those beyond low-Earth orbit where the International Space Station is situated, said Shelby Hopkins, senior systems engineer for Lockheed's Orion program. Advertisement "Deep Space has really unique environment and is more dangerous than low-Earth orbit, so we have to consider things like increased radiation ... it forces us to come up with innovative solutions," Hopkins said duri...
Modern humans moved into Western Europe 5,000 years earlier than previously thought

Modern humans moved into Western Europe 5,000 years earlier than previously thought

Science
Sept. 28 (UPI) -- Modern humans were occupying parts of Western Europe at least 38,000 to 41,000 years ago, 5,000 years earlier than previously thought. The discovery and analysis of ancient stone tools in a Portuguese cave -- detailed Monday in the journal PNAS -- suggests modern humans were along Europe's Atlantic Coast at the same time that Neanderthals occupied the region. Advertisement Paleontologists have been excavating the Portuguese cave known as Lapa do Picareiro for more than 25 years, but until now, researchers had failed to turn up evidence that modern humans might have arrived prior to the disappearance of local Neanderthals. During recent digs, researchers unearthed stone tools similar to those associated with early human populations at the other end of the continent, where...
