Astronomers have known about these objects for decades, but in the depths of cosmic time, it's hard to understand how they can grow so quickly -- or maybe not!
For decades the common wisdom of parenting manuals was that teenagers feel invulnerable, immortal, and simply perceive less peril in dicey situations and believe they have much more control than they actually do. In short, they underestimate life's very real risks and dangers. But scientists who study adolescent decision making now dispute this common parenting wisdom.
No, climate change is not experiencing a hiatus. No, there is not currently a "pause" in global warming. Despite widespread such claims in contrarian circles, human-caused warming of the globe proceeds unabated.
Perhaps more than any other group, athletes have fully embraced sleep as a performance enhancement tool. Top athletes are, of course, all about results. So there's no better place than the world of sports to see the tangible effects of sleep (including pre-game naps) on performance.
We take for granted the impact of the physical and biological sciences on our world, forgetting that it once took months to get from the east coast to the west coast or to communicate with someone across the ocean.
The waves of bubonic plague that washed through medieval Europe might have been driven by gerbils, not rats.
This unilateral focus on the dark side has had the unintended effect of blinding us to one of the most obvious and inspiring features of the experiment: it also showed that hundreds of ordinary people -- though the minority of Milgram's participants -- did in fact have what it takes to stand up for what is right.
In polls the American public has shown pride in the country's accomplishments in space exploration, along with concern about the costs involved. A review of public attitudes about the space program, from the Roper Center for Public Opinion Research archives.
The first step to solving problems is to identify and understand them. With that in mind, here is a list of five reasons why some liberals are just as bad, or at least almost, as creationism-believing conservatives when it comes to spreading pseudoscience.
Their research, a hydroponic plant growth system that relies on centripetal force to work in microgravity, almost ended there, until they met someone with industry experience and an alternative way to raise capital.
Sports create a relationship between the fan and the players. This relationship resembles that of a family. Sports fans, like other people, separate themselves out into similar groups with common values, religions, aesthetics, ethnicities and so forth.
Becoming an astronaut is easily the dream of many but sometimes that's all it ever is -- a dream. For Leland, who happens to be the 13th African American astronaut, that all became a reality through patience, hard work, and a knack for problem solving.
When it comes to scientific topics, both scientists and laypeople hide behind the excuse that the general public in this country simply doesn't have the education to process such complex information. This is leading to real problems.
At tonight's Oscars we'll no doubt see some familiar faces winning that coveted gold statuette. It's no secret that these sparkling little men aren't 100% gold--they're only coated in 24-carat gold--so that makes it harder to figure out how much gold they actually contain. Luckily math comes to the rescue.
Gender bias is real and it is worse in engineering. Even engineering students rate average female professors more harshly than an average male professor.
At a time when endorsement of Darwinism is reflexively identified with belief in evolution, it may come as a surprise that alternative accounts are gaining acceptance. Scientists studying the history of life on Earth are increasingly moving beyond the nineteenth-century theory, and concepts and insights that were unknown to the founding figures are now on the table.
Since Aristotle and long before, people who have been privileged to spend time observing and interacting with elephants have expressed similar sentiments.
To doubt evolution at this late date is to reveal oneself to be willfully, invincibly ignorant of basic scientific principles. And there is no room in the Oval Office -- none -- for the scientifically illiterate.
While there are a lot of hurdles associated with colonizing Mars, the ability to have a cold beer might just make the goal a little more appealing.
