We know a lot about the history of life on Earth, but how it began is still one of our greatest scientific mysteries. One hypothesis is that life actually originated on another planet, and many scientists today take the idea quite seriously.
A group of self-identified terrorists has sent several mail bombs to nanotechnology labs and researchers in Latin America, injuring two people earlier this month in the engineering department at the Monterrey Institute of Technology outside Mexico City. In an online manifesto, the group calls itself Individualists With Savage Tendencies (this a translation from the Spanish, Individualidades tendiendo a lo salvage, or ITS), and writes about how they are trying to stop a “gray goo” scenario where self-replicating nanobots destroy the world.
Could the next wave of Occupy protests be ripped apart by rubber bullets and tear gas launched by remote-controlled robots hovering overhead, steered by police officers miles away? It’s not a futurist scenario anymore. According to CBSDC:
Archaeologists recently found a 2,700-year-old pot stash, so we know humans have been smoking weed for thousands of years. But it was only about 20 years ago that neuroscientists began to understand how it affects our brains.
Imagine a tyrannosaur weighing one and a half tons, completely covered in soft, downy plumage. Even its tail is fluffy with feathers. Though we’ve known for a while that many dinosaurs were covered in feathers, a group of Chinese researchers have now provided direct evidence that gigantic, deadly tyrannosaurs might have looked a bit like wuffly birds.
In a survey taken of over 4,000 scientists across the globe, 70% of whom were men, researchers found that people consider science a “family unfriendly” career. Over half of survey respondents said that work clashed with family responsibilities several days per week. While women in the sciences have long complained of problems with work/family life balance, this is one of the first studies to reflect widespread male dissatisfaction with the same issue.
A scientific study has now confirmed what many women have known for ages, which is that certain types of exercise can induce orgasm. Indiana University health researchers Debby Herbernick and Dennis Fortenberry have just conducted a study of hundreds of women who report “exercise induced orgasms” (EIO), or “coregasms.”
Thousands of women have had to get their breast implants removed after a French company, Poly Implant Prothese (PIP), admitted that they had used industrial grade silicone in the implants. Not only was this class of silicone not approved for medical use, but some of it also contained fuel additives. Basically, PIP pumped some plastic bags full of silicone intended for use with fuels and food products - and then sold them as implants. Not surprisingly, the implants had a high breakage rate and many women had to get them removed even before news of the company’s misdeeds was made public in 2010.
Humans want to believe that they’re the smartest creatures on the planet. But the more we understand octopuses, the more it seems that we may not be alone in our ability to solve problems, make complex connections between ideas, and survive by wits alone. A growing body of evidence — a lot of it still anecdotal — suggests that octopuses show elements of human-like intelligence.
