Five distinct dog types existed 11,000 years ago: Study

Scientists have mapped the DNA of 27 ancient dogs spanning back 11,000 years and found that there were at least five different types of dogs present at the end of the last Ice Age. For the study, published in the journal Science, the research team studied dog DNA dating as far back as 11,000 years ago, immediately following the last Ice Age. By sequencing the DNA of 27 dogs found in Europe, the Near East and Siberia, team members discovered five different types of dogs with distinct genetic ancestries dati........

Brains plan for action, not limbs

The brain isn’t going out on a limb when choosing to grasp things. Instead, new research shows, there is an overarching system where the brain uses action-specific regions to respond to a choice of action, such as reaching or grasping, regardless of the limb used to perform that action. In a described in the journal PNAS, a team led by Yuqi Liu of Georgetown University Medical Centre, US, found that reaching for an object with your feet engages the same part of your brain as reaching with your hand. As well ........

Multi-screening may mess with your memory

Why do some people have better memories than others? This question has taken on new significance with the explosion of digital culture, which has been memory failure. A new study by Stanford University researchers, in the journal Nature, has shed more light on this by linking attention lapses in habitual media multi-taskers to poorer memory. People who reported engaging in multiple forms of digit........

MIT comes up with skin like device to help ALS patients

People who suffer from amyotrophic lateral sclerosis (ALS) often experience a gradual decline in their ability to control their muscles and as a result, they could even face difficulties to communicate properly. And now, a team of researchers at the Massachusetts Institute of Technology (MIT) has found a solution to this problem. Researchers who took part in this study have developed a skin-like device that can be attach........

Zombie diet: 10 real-life examples of humans eating humans

In any zombie horror story, the undead human corpses roam the world in their hunt for human flesh. Now, we know aren't real, but human cannibalism is far from fictional. Here are 10 real-life examples of human flesh-eaters that are just about as horrifying as zombies. Cannibalism goes way, way back. Around 900,000 years ago in what is now Spain, Homo antecessor, an ancient relative of humans, , accord........

Water ice on the Moon may be easier to reach than we thought, new studies claim

New observations of the Moon reveal that lunar water may be more accessible than originally thought. The new data is particularly exciting for NASA, which hopes to leverage the Moon’s resources — notably water ice embedded in the soil — to help future astronauts live and work on the lunar surface. In one study, researchers detected water directly on the lunar surface, finding the molecule on areas of the Moon lit by the Sun. A second study speculates that water ice might be trapped in tiny pockets or small craters littered all over the Moon’s surface, making water........

Devi Mahatmyam - An Ancient Hindu Text Encoding Profound And Futuristic Brain Science?

Neurologist explains what makes the ancient Hindu text Devi Mahatmyam an incredibly profound and futuristic work of philosophy and science. Neurosurgery, in many ways, can be considered the acme of Western science. In the fine operations performed on the microscopic structures of the brain, neurosurgery harnesses the Western mind’s aptitude for rigour, reproducibility, systematisation, and concreteness. Within neurosurgery, perhaps the most cutting-edge subfield is known ........

How many satellites orbit Earth and why Space Traffic Mgmt is crucial

Have you ever wondered how many satellites orbit the Earth? According to the Union of Concerned Scientists (UCS), which maintains a of active satellites in orbit, as of April 1, 2020, there were a total of 2,666 satellites in Space, of which 1,918 were in low Earth orbit (LEO). And this is only till April. Since then we have had many more launches. The busiest among the lot being SpaceX, which has been launching satellites at an a........

A new attempt to get water from the air

US and Korean researchers say they are a step closer to developing a practical way to extract drinkable water directly from the air, even in dry regions. The team unveiled the design for its solar-powered system in 2017 and updated it the following year, describing the work in a in the journal Nature Communications. It works, they say, by harnessing a temperature difference within the device to allow an adsorbent material ........

Indian Scientists Develop Synthetic Material That Opens Up Prospects Of Smart Materials For Energy And Biotech Sector

Indian scientists have developed a synthetic material that mimics the dynamic capability of living organisms to adapt to new environments by utilizing simple natural design principles to create complex networks. The new materials developed opens new avenues for smart materials because of their dynamic and adaptive nature. Hence, they would be useful as recyclable polymers for the energy and biotechnology sector, a Ministry of Science and Technology said on Saturday (17 October). Reduction–oxidation (redox) processes are central to many biological functions. Ce........

By 2100, Greenland will be losing ice at its fastest rate in 12,000 years

Greenland’s ice sheet (shown) has advanced and retreated many times over millennia. But new research shows the rate of ice loss is ramping up, and will be the fastest in 12,000 years by 2100. 00 am By 2100, Greenland will be shedding ice , scientists report October 1 in Nature. 8/2/19). Meltwater from the island’s ice sheet now contributes about to global sea level rise (SN: 9/25/19). But how does this rapid loss stack up against the ice sheet’s recent history, including during........
