Asteroids are sometimes called loose rubble piles, which leads to interesting effects if they happen to get close to a planet. A science team in 2010 found out that when asteroids get close to Earth, the gravity of our planet can stir up the dust grains and “refresh” its face, in a sense. Now, scientists have found that Mars can do the same thing.
Floating nuclear co-generation plant (FNCP) “Akademik Lomonosov”, is world’s first pilot design of the set of small transportable power plants. Will be capable of generating up to 70 megawatts (MW) of electricity, enough to provide electricity to a city of 200,000 people.
ESA’s volunteers recently finished their third and last session resting in bed in the interest of spaceflight and science. They can return to their normal lives after spending their last 21 days in bed with their feet up.
Scientists using satellite, radar and geological technology, have found in Kenya a very large undergroundwater reserve, that it could meet the country’s water needs for the next 70 years.
Researchers at Oregon Health & Science University developed an HIV/AIDS vaccine candidate, that appears to have the ability to completely clear an AIDS-causing virus from the body.
What’s new in the outer reaches of our solar system? Try the discovery of a Trojan asteroid orbiting Uranus. While a plethora of puns exist for this simple fact, the reality check is that this means there are far more of these objects out there than astronomers expected. The new Trojan even has a name – 2011 QF99!
Are we all Martians? Are we the Aliens? Professor Steven Benner has claimed that life on Earth may have come from Mars on an asteroid.
For the first time scientists have completed successful human trials of a malaria vaccine, providing 100% protection against the often fatal disease.
In the new story of the solar system, the future is a bit dicey, and it all began in chaos. The dust speck had been plucked from the tail of a comet more than 200 million miles away.
Consider this. The Universe is enormous.
We don’t live in a perfect world, and neither do gases – it would be great if their particles always fulfilled the assumptions of the ideal gas law, and we could use PV=nRT to get the right answer every time. Unfortunately, the ideal gas law (like our culture) has unrealistic expectations when it comes to size and attraction: it assumes that particles do not have size at all and that they never attract each other. So the ideal gas “law” often becomes little more than the ideal gas estimate when it comes to what gases do naturally. But it’s a close enough estimate in enough situations that it’s very valuable to know. In this episode, Hank goes through a bunch of calculations according to the ideal gas law so you can get familiar with it.
Although it may sound crazy, many doctors use maggots today to clean wounds of dead and infected tissue. This process, called debridement, is important for preventing the spread of infection in a world of increasing antibiotic resistance. Hank has more details on the marvelous maggot in today’s episode of SciShow.
In a recent progress article in Nature Geoscience, this issue is tackled head on and here, in the inaugural NPG journal club, the worlds of Geoscience and Google+ met to discuss the article and this big climate question.
The classic film Deliverance immortalized the American tradition of canoes, river canyons, guitars and banjos—but less remembered from the film, and the novel that preceded it, is its very premise: Four men were out to see one of Appalachia’s last free-flowing rivers—the fictional Cahulawassee—months before a scheduled dam project forever disrupted its flow. This fate, or something […]
Last December, when a private space exploration company named Golden Spikeannounced they are working to offer human expeditions to the Moon by 2020, they also said wanted to bring public along as an integral part of the company’s mission. Since their initial announcement, the Golden Spike team says they’ve been inundated with emails, letters and social media posts from people wanting to know how to take part, and how they could help speed the development of human lunar expeditions.
