Antarctic research station to be shut down for winter

Antarctic research station to be shut down for winter

A research station in Antarctica will be shut down between March and November this year as a growing crack in a massive ice shelf is posing a real threat, according to the British Antarctic Survey.

The Halley VI Research Station in Antarctica is located on a floating Brunt Ice Shelf that sticks out into the Weddell Sea. There are several cracks in the ice shelf and one of them is continue to grow to reach near the research station.

Moon Express pushes ahead with its plans to mine Moon

Moon Express pushes ahead with its plans to mine Moon

Pushing ahead with its ambitious goal to mine the Moon, California-based Moon Express has raised enough funds for launching a trip to the only natural satellite of Earth.

Moon Express is a Mountain View-based team for the international Google Lunar X Prize competition. Achieving another milestone, the team has thus far raised a total of $45 million in funding from a number of private investors.

Scientists turn mice into vicious killers by manipulating brain neurons

Scientists turn mice into vicious killers by manipulating brain neurons

A team of scientists at Yale University turned around a dozen ordinary mice into killing machines by manipulates neurons using light using a technique called optogenetics.

The researchers shone laser on a cluster of neurons in the amygdala part of the lab mice’s brains, which tensed the lab mice’s jaw and neck muscles. They found that stimulating the amygdala part of the animals’ brains turned them into cruel predators.

Researchers turn mice into bloodthirsty killing machines

Researchers turn mice into bloodthirsty killing machines

A new research demonstrated how stimulating a certain part of the brain can turn a happy creature into a bloodthirsty killing machine.

Yale University researchers shone laser on a cluster of neurons in the amygdala part of the brains on the otherwise their brains, which in turn tensed the lab mice’s jaw and neck muscles. The behavior didn’t occur when they stimulated the mice’s other brain parts.

They were surprised to find that stimulation of the amygdala part of the mice’s brains turned them into vicious predators that attacked nearly anything that came in their paths.

Researchers activate killer instinct in mice using laser

Researchers activate killer instinct in mice using laser

Predatory behaviors like grabbing and biting are quite familiar to fans of nature documentaries, but the brain circuits responsiblefor such behaviors remain a mystery. Some studied indicated that an almond-shaped area of the brain called the central amygdala is involved in a creature’s predatory actions.

Now, a team of researchers claimed to have successfully activated killer instinct by stimulating the central amygdala in mice using laser.

Baboons can make human-style vowel sounds: study

Baboons can make human-style vowel sounds: study

Speech is one of the key characteristics that separate humans from their relatives, non-human primates. Widely-accepted theory is that humans have a low larynx, while primates have a high larynx, and one can’t produce various distinct vowel sounds without low larynx.

But, a new study is forcing experts to change their thinking as it showed that vowel sounds aren’t a unique characteristic of human vocalizations, baboons too can produce at least five vowel sounds as part of their calls.

Chile’s Very Large Telescope to be upgraded

Chile’s Very Large Telescope to be upgraded

The planned upgrade to Chile-based Very Large Telescope (VLT) is expected to help scientists find and explore new exoplanets by making it possible for mini-probes to go where no probe has thus far gone.

The European Southern Observatory (ESO) recently hit an agreement with the Breakthrough Initiatives program to fund the VLT upgrade. In return, the powerful telescope will train its sharper lenses on the rocky exoplanet Proxima b, which may serve as a probable target for future space missions.

Researchers suggest multiple-impact theory for Moon’s formation

Researchers suggest multiple-impact theory for Moon’s formation

Earth’s only natural satellite Moon came into existence as a result of merger of several small moonlets or disks of planetary debris created by multiple objects’ collision with our planet, a new study suggests.

According to the new study, as many as 20 Moon-to-Mars-size objects collided with Earth, flinging debris from our planet into orbit. That debris formed disks around the planet, making it looking somewhat ringed Saturn. Over the following many centuries, the debris accreted to form moonlets that eventually merged to produce the Moon.
