Professors Tom Marsh and Boris Gänsicke of the University of Warwick's Astrophysics Group, with Dr David Buckley from the South African Astronomical Observatory, have identified the star AR Scorpii (AR Sco) as the first white dwarf version of a pulsar -- objects found in the 1960s and associated with very different objects called neutron stars.
The white dwarf pulsar has eluded astronomers for over half a century.
AR Sco contains a rapidly spinning, burnt-out stellar remnant called a white dwarf, which lashes its neighbour -- a red dwarf -- with powerful beams of electrical particles and radiation, causing the entire system to brighten and fade dramatically twice every two minutes. The latest research establishes that the lash of energy from AR Sco is a focused 'beam', emitting concentrated radiation in a single direction -- much like a particle accelerator -- something which is totally unique in the known universe.
Scientists from the Massachusetts Institute of Technology (MIT) have created a device worn on the wrist that uses artificial intelligence to read the tone of conversations. The wristband of the device is loaded with sensors that capture physiological data such as heart rate, blood pressure, blood flow, temperature and movement.
The MIT team combined that information with audio recordings to analyse a conversation's pitch, energy levels and vocabulary in the development of an algorithm that assesses the tone with an 83% accuracy level.
It understands happy, sad or neutral tones and some versions could tell you if you're boring others by collecting negative signs such as pauses, fidgeting and putting a hand to one's face.
The device could be linked to smartphones that would then vibrate if a conversation was going downhill, researchers said. The prototype focuses on the wearer, but later versions could also analyse audio from all sides of a conversation, telling us whether the people we are with are still interested in what we are saying.
Melih Gokcek, who has been mayor of the Turkish capital since 1994, made the outlandish claims on Twitter where he regularly updates his more than 3.7 million followers, often writing in capital letters.
His comments were made after two quakes hit the western Canakkale province on Monday and Tuesday morning, measuring 5.3 and 5.2 magnitude respectively, the Turkish Disaster and Emergency Management Authority (AFAD) said.
In these tweets, Gokcek shared a video which claimed there were tools for causing manmade quakes, and he called all submarines and ships with large equipment to be taken under control of the authorities.
According to the Washington Post, researchers found the prints - one of which measures about 42-inches long and 30-inches across - in the Gobi Desert about two months ago.
In addition to the size, the fossil is considered to be fairly well-preserved with claw imprints that are still visible. Archaeologists suspect the mark was made by a massive dinosaur known as a Titanosaur which is believed to have exceeded 100-feet in length and 65-feet in height. They think the large creature may have stepped in some mud, and the hole was quickly filled in with sand or other materials to preserve the impression.
A geologic analysis of the adjacent area has traced the specimen to the Upper Cretaceous period which dates back around 70 million to 90 million years ago.
Researchers are currently looking for any remains from the dinosaur that could have made the footprint.

The new research means scientists will have to dig deeper to explain evidence of water on the planet.
For ancient Mars to accommodate water, conditions on the surface of the Red Planet would have had to be much warmer than today and with greater carbon dioxide levels forming a protective greenhouse-gas blanket.
However, new research from NASA has thrown further confusion into theories about water on Mars after the Curiosity rover uncovered rocks indicating the existence of a lake - but no signs of the carbon levels required to keep that water unfrozen.
The blanket of clouds ripple as they cut around the British islands in the southern Atlantic ocean "like a ship carving its way through the sea" by a phenomenon known as "gravity waves".
Gravity waves are formed by the rise and fall of colliding air. Here, moist air from the ocean is pushed down by gravity but then forced back up again by the dry air below rising from from the islands.
The movement keeps repeating over and again, creating a stunning pattern in the clouds.
Families of bacteria cells are known to kill adjacent, unrelated cells by injecting them with toxins - now researchers have found that cells which compete in this way are able to flourish.
Their approach creates surviving pockets of closely related bacteria with a common interest in ensuring their collective genes are passed on to future generations.
The bugs live alongside one another, cooperating to share tasks and resources such as nutrients.
Unrelated microbes, which might cheat by taking resources without contributing, are excluded from the group.
Scientists carried out experiments and created mathematical models of cholera bacteria to better understand how microbes organise themselves in their typically packed populations.
They found that the stabbing tactic - which has no effect on genetically similar relatives - helps create clusters of bacteria that cooperate with each other.
The latest in this developing drone menagerie appears to represent the next stage of evolution, a sophisticated miniature drone modeled after a bat that developers are simply calling Bat Bot. As featured by Popular Mechanics:
Bat Bot is nothing short of an engineering marvel. It weighs in at only 3.3 ounces—about as heavy of two golf balls. With a silicone membrane stretched over its carbon-fiber skeleton, a head crammed with an on-board computer and sensors, and five micro-sized motors strung along its backbone, Bat Bot is capable of autonomous, flapping flight. Designed by trio of roboticists led by Soon-Jo Chung at Caltech, it was unveiled today in the journal Science Robotics.
Michael Jäger of Stixendorf, Austria, took the picture on Dec. 31, 2016, just as the comet was swinging around the sun en route to Earth. Since then 45P's icy nucleus has been heated by solar radiation, causing it to spew brightening jets of gas into the comet's green atmosphere. Why green? Because the comet's vaporizing nucleus emits diatomic carbon, C2, a gas which glows green in the near-vacuum of space.
According to the Minor Planet Center, this is the 8th closest pass of any comet in the modern era (since ~1950, when modern technology started being used to study comets). It will only be 31 times farther from Earth than the Moon.
Interestingly, 45P made an even closer approach on its previous orbit (23 lunar distances), so it is also on the list as the 5th closest.
Proximity makes the comet bright despite its small size. Forecasters say 45P could be on the verge of naked eye visibility (6th magnitude) when it emerges into the pre-dawn sky later this week. The best time to look is during the dark hours before sunrise between Feb 9th and 12th. The comet will be racing through the constellation Hercules high in the eastern sky. Sky maps: Feb. 9, 10, 11, 12.
Got a great picture? First, submit it to Spaceweather.com. Next, send it to the Planetary Science Institute, which is collecting amateur images to help professional researchers study Comet 45P. More resources: 3D Orbit, Ephemeris.
A new study from University of Michigan researchers used MRI scans to examine how astronauts' brains compress and expand in spaceflight. The findings could have implications for treating other health conditions that affect brain function.
The retrospective follow-up study is believed to be the first to examine structural changes during spaceflight. Results show that the volume of gray matterincreased or decreased, and the extent of the alteration depended on the length of time spent in space.
GRAY MATTER ALTERATIONS
Researchers looked at structural MRIs in 12 astronauts who spent two weeks as shuttle crew members, and 14 who spent six months on the International Space Station. All experienced increases and decreases in gray matter in different parts of the brain.














Comment: As evidenced in our 2010 article, Connecting the Dots: Mass murder in Haiti, plane madness in the skies, 'man-made' earthquakes as a means of warfare is not a fantastical or outlandish claim.
