  • A new research may help identify a person by analyzing their hair
  • According to researchers, Hair contains unique protein markers which help with the identification
  • Chemist Brad Hart, Director of the Forensic Science Center and co-author of the paper said this would be game-changing in the field of forensic science

September 12, 2016: Your hair could be just as unique as your DNA, according to new research.

Writing in the journal PLOS ONE, researchers from the Lawrence Livermore National Laboratory say unique protein markers in hair could be used to make forensic and archeological identification easier.

Moreover, the proteins are more durable over time, while DNA can deteriorate.

To reach their conclusions, the researchers looked at hair samples that were “up to 250 years old” along with samples from 76 living humans. The researchers say they’ve found 185 protein markers to date, which they think would be enough to identify an individual from a population of one million.

The researchers say they hope to find “around a hundred” core markers that could be used to “distinguish an individual among the entire world’s population using a single hair.”

“We are in a very similar place with protein-based identification to where DNA profiling was during the early days of its development,” said LLNL chemist Brad Hart, the director of the lab’s Forensic Science Center and co-author of a paper discussing the work. “This method will be a game-changer for forensics, and while we’ve made a lot of progress toward proving it, there are steps to go before this new technique will be able to reach its full potential.” (VOA)

Stephen Hawking believes Technology could end Poverty and Disease, says Artificial Intelligence could be the Worst or Best things for Humanity

Hawking said everyone has a role to play in making sure that this generation and the next are fully engaged with the study of science at an early level to create “a better world for the whole human race.”

Lisbon, November 7, 2017 : Technology can hopefully reverse some of the harm caused to the planet by industrialization and help end disease and poverty, but artificial intelligence (AI) needs to be controlled, physicist Stephen Hawking said on Monday.

Hawking, a British cosmologist who was diagnosed with motor neuron disease aged 21, said technology could transform every aspect of life but cautioned that artificial intelligence poses new challenges.

He said artificial intelligence and robots are already threatening millions of jobs — but this new revolution could be used to help society and for the good of the world such as alleviating poverty and disease.

“The rise of AI could be the worst or the best thing that has happened for humanity,” Stephen Hawking said via telepresence at opening night of the 2017 Web Summit in Lisbon that is attended by about 60,000 people.

“We simply need to be aware of the dangers, identify them, employ the best possible practice and management and prepare for its consequences well in advance.”

Hawking’s comments come during an escalating debate about the pro and cons of artificial intelligence, a term used to describe machines with a computer code that learns as it goes.

Silicon Valley entrepreneur Elon Musk, who is chief executive of electric car maker Tesla Inc and rocket company SpaceX, has warned that AI is a threat to humankind’s existence.

But Microsoft co-founder Bill Gates, in a rare interview recently, told the WSJ Magazine that there was nothing to panic about.

Stephen Hawking said everyone has a role to play in making sure that this generation and the next are fully engaged with the study of science at an early level to create “a better world for the whole human race.”

“We need to take learning beyond a theoretical discussion of how AI should be, and take action to make sure we plan for how it can be,” said Stephen Hawking, who communicates via a cheek muscle linked to a sensor and computerized voice system.

“You all have the potential to push the boundaries of what is accepted, or expected, and to think big. We stand on the threshold of a brave new world. It is an exciting — if precarious — place to be and you are the pioneers,” he said. (VOA)

Astronomers discovered Sun-like star that devoured its own planets

New York, Oct 13: Astronomers have discovered that a Sun-like star lurking around 350 light-years away consumed the rocky equivalent of 15 Earths.

Dubbed Kronos after the child-eating Titan of Greek mythology, the star is the clearest and most dramatic case yet of a Sun-like star consuming its own planets, said Semyeong Oh, astrophysicist at Princeton University in New Jersey and lead author of the study.

“Even if our Sun ate the entire inner solar system, it wouldn’t come close to the anomaly we see in this star,” study co-author David Hogg from the Flatiron Institute in New York added.

The research did not begin as a hunt for a planet-eater.

Oh was analysing a catalog of new star data collected by the European Space Agency’s Gaia spacecraft for pairs of stars with similar speeds and trajectories.

Such duos are typically twin stars that formed close together from the same ingredients.

The analysis ultimately led to the identification of Kronos and its lesser known brother Krios.

Their official designations are HD 240430 and HD 240429, and they are both about 350 light years from Earth.

The keys to the discovery were first confirming that the widely separated pair are in fact a binary pair, and secondly observing Kronos’ strikingly unusual chemical abundance pattern, Oh explained in a statement released by the Princeton University.

Other co-moving star pairs have had different chemistries, Oh explained, but none as dramatic as Kronos and Krios.

Most stars that are as metal-rich as Kronos “have all the other elements enhanced at a similar level,” she said, “whereas Kronos has volatile elements suppressed, which makes it really weird in the general context of stellar abundance patterns.”

In other words, Kronos had an unusually high level of rock-forming minerals, including magnesium, aluminium, silicon, iron, chromium and yttrium, without an equally high level of volatile compounds — those that are most often found in gas form, like oxygen, carbon, nitrogen and potassium, the study said.

Researchers Claim The Existence Of Planet Nine

Researchers from an American University have laid evidences to prove the presence of Planet Nine

Kuiper Belt indicates the presence of Planet Nine
  • The science communities since a long time have been debating upon the existence of Planet Nine. 
  • Space highlights different shreds of evidence based on which scientists are stating the claim.

What Is Planet Nine?

Planet Nine is a hypothetical planet present in the far outer Solar System, whose mass is estimated to be 10 times more than the mass of Earth. The planet is said to be 20 times farther than the sun than Neptune is.

What Do Researchers Have To Say?

Dr Konstantin Batygin, a planetary astrophysicist at the California Institute of Technology, said that there were five different lines of observational evidence which pointed to the existence of Planet Nine. He stated that if this theory does not sound believable, then people would have to come up with the answers of the five pieces of evidence which could lead to further confusion.

Batygin in 2016 published a study examining the six known objects in the Kuiper Belt, a  circumstellar disc in the Solar System beyond the planets that extends from the orbit of Neptune towards interstellar space.

The study examines all the objects have elliptical orbits pointing in the same direction and are tilted the same way. These serve as evidence to the planet’s existence.

It is being said that the objects are tilted 30 degrees downward compared to the plane where the eight official planets circle the sun. Researchers also made use of computer simulations of the solar system including the Planet Nine and to demonstrate that there should be more objects tilted a whopping 90 degrees to solar plane. It was revealed that five such objects, which fit these parameters were already known.

The study led to the birth of two more ideas. Researchers said that this planet could have tilted the planets of the solar system during the last 4.5 billion years.

Planet Nine’s existence could also tell the reason as to why Kuiper Belt objects orbit in the opposite direction as compared to other things in the solar system.
