Fact meets science fiction: For the last five days there has been no contact with the Russian scientists drilling down more than two miles to Lake Vostok in Antarctica.
The team from Russia’s Arctic and Antarctic Research Institute (AARI) have been drilling for weeks in an effort to reach isolated Lake Vostok, a vast, dark body of water hidden 13,000 ft. below the ice sheet’s surface. The lake hasn’t been exposed to air in more than 20 million years.
Priscu said there was no way to get in touch with the team — and the already cold weather is set to plunge, as Antarctica’s summer season ends and winter sets in. “Temps are dropping below -40 Celsius [-40 degrees Fahrenheit] and they have only a week or so left before they have to winterize the station,” he said. “I can only imagine what things must be like at Vostok Station this week.”
Another superEarth has been found orbiting a star in the habitable zone.
Another superEarth has been found orbiting a star in the habitable zone.
An M-class dwarf star called GJ 667C, which is 22 light-years away from Earth, had previously been observed to have a super-Earth (called GJ 667Cb) that orbited the star in only 7.2 days, making it too close to the star, and thus too hot, to support life.
The study started with the aim of learning more about the orbit of GJ 667Cb. But the research team found a clear signal of a new planet (GJ 667Cc) with an orbital period of 28.15 days and a minimum mass of 4.5 times that of Earth.
Though the planet is much closer to its star than the Earth, the star itself is much smaller and dimmer, so overall the planet gets about the same amount of energy as the Earth.

The face in space
The hotbed of star birth, called NGC 3324, is full of hot young stars, whose ultraviolet radiation is making the gas clouds glow. The stellar wind and radiation from the newborn stars has also punched out a cavity in the surrounding gas and dust. The edge of the wall of gas and dust at the right in the photo resembles the profile of a human face, with a ridge in the center that looks like a nose.

We found the potential risk of public harm to be of unusually high magnitude. In formulating our recommendations to the government, scientific journals and to the broader scientific community, we tried to balance the great risks against the benefits that could come from making the details of this research known. Because the National Science Advisory Board for Biosecurity (NSABB) found that there was significant potential for harm in fully publishing these results and that the harm exceeded the benefits of publication, we therefore recommended that the work not be fully communicated in an open forum. The NSABB was unanimous that communication of the results in the two manuscripts it reviewed should be greatly limited in terms of the experimental details and results.
As much as I am almost always in favor of the free flow of information, in this case this recommendation seems quite reasonable. The situation is in many ways identical to the government’s policy to routinely limit publication of the engineering details of its weaponry.
