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.

U.S. flu season continues to pick up as European levels remain high

U.S. flu season continues to pick up as European levels remain high

The United States’ flu season continues to pick up more steam, as several countries in Europe are grappling with a busy flu activity led by the H3N2 strain that particularly poses a threat to the seniors.

In its latest update, the U.S. Centers for Disease Control & Prevention (CDC) said that all ten of its regions are exceeding their baseline percentages of clinic visits for flulike illness for the first time so far this season. The nation as a whole has also been above its baseline for the marker for fourth consecutive week.

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.

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.

Peanut based diet for toddlers at early age can prevent allergy: Report

Peanut based diet for toddlers at early age can prevent allergy: Report

Peanut allergy is a major issue for many people in the United States and in many other countries across the world. However, new guidelines by National Institutes of Health suggest that kids should be given small amounts of peanuts at early age to ward off the risk of allergy later in life. The guidelines suggest that before first birthday, kids in high risk group for peanut allergy should be given foods having small amounts of peanuts. Earlier research has suggested that if pregnant women eat peanuts and other nuts regularly, they can reduce the risk nut allergy among kids.

NASA’s asteroid missions to take us back into beginning of solar system

NASA’s newly announced Lucy and Psyche space probes will take us back into the beginning of our solar system – around 10 million years after the Sun was born.

Both Lucy and Psyche missions will be robotic and unmanned endeavors that will be controlled remotely by NASA scientists from Earth.

Two stars will burst into red nova in 5 years: astronomers predict

Two stars will burst into red nova in 5 years: astronomers predict

A binary star discovered last summer in the constellation Cygnus will burst into a red nova in next five years, according to a study presented at the American Astronomical Society (AAS) meeting in Grapevine, Texas.

Presenting the findings of the new study, Larry Molnar of Calvin College predicted that the two stars in the system with slam into one another sometime in 2022, creating a brick-red beacon that will be so bright that night sky gazers on Earth will be able to see it with the naked eye.
