This girl beats Einsten in IQ

An 11-year-old schoolgirl has achieved the highest points in Mensa IQ Test, beating the renowned scientists Albert Einstein and Stephen Hawking. Tara Sharif scored 162 points, the highest score possible and well above the ‘genius benchmark’ of 140. “I was shocked when I got the result. I never expected to get such a good score,” says Tara. Tara took the non-verbal test in Oxford, which involved understanding the meaning of words and answering a set of questions in the prescribed time. Tara hails from Borazjan county in the Southern Iranian Bushehr Province. Her father said that he is extremely proud of her and also surprised at how well she scored. “I knew she is intelligent but such a great success was unexpected to me,” he said. The 11-year-old shared her future plans after acing the Mensa IQ Test. “When I am older, I would like to do something related to mathematics,” she said. Tara is now eligible for the membership of Mensa, which is also known as the ‘high IQ society’.

10 Myths about sleep

Wake up, people: You're fooling yourself about sleep, study says

Robbins and her colleagues combed through 8,000 websites to discover what we thought we knew about healthy sleep habits and then presented those beliefs to a hand-picked team of sleep medicine experts. They determined which were myths and then ranked them by degree of falsehood and importance to health.
Here are 10 very wrong, unhealthy assumptions we often make about sleep, an act in which we spend an estimated third of our lives -- or, if we lived to 100,

1. Adults need five or fewer hours of sleep "If you wanted to have the ability to function at your best during the day, not to be sick, to be mentally strong, to be able to have the lifestyle that you would enjoy, how many hours do you have to sleep?" asked senior study investigator Girardin Jean-Louis, a professor in the Department of Population Health.

2. It's healthy to be able to fall asleep 'anywhere, anytime' Falling asleep as soon as …

Scientists reveal all humans able to sense magnetic fields

Scientists believe that humans were once able to sense the Earth's magnetic field and use it for navigation purposes, just like many other living beings do, but eventually lost this skill. They suggest that it's possible to regain that skill once again, possibly with some kind of training.

A group of scientists, including a geophysical biologist, a cognitive neuroscientist and a neuroengineer, has found proof that the human brain is capable of detecting Earth's magnetic field despite previous conflicting results.

The results of their research were published on the website Science Alert. The discovery shows that humans haven't entirely lost the mechanism of orienting themselves using the magnetic field, which many other animals enjoy.

The researchers placed the experiment subjects on a simple chair set up inside a Faraday cage that filters out all outside magnetic fields and then they used the coils installed inside to generate an artificially controlled magnetic field…

NASA Detects Asteroid Explosion 10 Times More Powerful Than Hiroshima Bomb

A weather satellite launched the first time captured images of a big fireball exploding in the Earth's atmosphere on Dec. 18, 2018, according to NASA.

The fireball that blasted over the Bering Sea near the Kamchatka Peninsula in Russia is considered to be the second largest of its kind in 30 years. It is also the biggest since the fireball that exploded in Chelyabinsk in February 2013.

Fireballs are very bright meteors that explode into the Earth's atmosphere.

How Powerful Was It?
The fireball unleashed energy that is equivalent to 173 kilotons of TNT. This is said to be 10 times stronger than the energy released by the "Little Boy" atomic bomb that was dropped in Hiroshima on Aug. 6, 1945.

The energy from the fireball is comparable to 40 percent of the energy released in the Chelyabinsk event.

The historic fireball in Chelyabinsk that radiated 440 kilotons created a staggering shockwave that shattered windows, damaged buildings, and caused 1,200 injuries.

The most …

NASA plans to send hot air balloons to detect earthquakes on Venus

Since our neighboring planet Venus has a very hellish atmosphere, studying more about the planet’s internal composition has been a bit difficult. But NASA has new plans to study the planet’s seismic activities through hot air balloons.

Space agency NASA is planning to study Venus’ earthquakes and other internal activities with the help of hot air balloons embedded up special earthquake sensors.

Earlier this month, NASA researchers set off a 50-ton chemical explosion 984ft below the surface of the Mojave desert. This artificial earthquake let NASA to test their special earthquake sensors that hung below the helium-filled balloons that floated hundreds of meters above the desert.

After studying Mars, NASA plans to send flying drones to Venus

NASA is hoping for a similar system for Venus to discover more about its internal structure. Balloons are chosen for this activity because landing up a rover in near to impossible due to Venus’ dense atmosphere of mostly carbon dioxide that is so h…

Ice Filled Crater on Mars

The Mars Orbiter Express has found an Ice filled Crater near the Martian North Pole. It looks like a snowy Landscape. The image was taken by ESA( European Space Agency )
Its name is Kerolov Cater and it is 81km long. Korolev Crater was named after Russian Sergei Korolev who is renowned as the father of Soviet space technologies. Ice mostly is frozen co2 and water. Mars express was sent in 2003.

Underwater volcano full of MUTANT sharks could BLOW any second

RARE mutant breeds of shark have been discovered lurking inside an underwater volcano spewing acid that could explode at any moment.
Stunned marine experts from National Geographic found the hammerhead sharks and rays drifting in Kavachi, an active volcano off the coast of New Guinea. The volcano last erupted in 2014 so the crew were shocked to find not just life but large carnivores circling its turbulent base. Ocean engineer Brennan Phillips told National Geographic: "The idea of there being large animals like sharks hanging out and living inside the caldera of this volcano conflicts with what we know about Kavachi, which is that it erupts.

“But when it’s erupting there’s no way anything could live in there.

“So to see larger animals like this that are living and could potentially die at any moment brings up lots of questions.

“Do they leave?

“Do they have some sort of sign that it’s about to erupt?
"That’s what makes discovering these animals down inside the volcano so …

Scientists are able to shrink objects

For the first time, researchers have produced nano-objects by shrinking. First, they assembled 3D objects in a special hydrogel, then an acid caused the gel and its contents to shrink. The 3D design thus became an object ten to a thousand times smaller - without distortions or defects. The big advantage: this "implosion fabrication" method is feasible with conventional technology and enables completely new nanoconstructs, as the researchers report in the specialist journal "Science".

Team invents a method to shrink objects to the nanoscale
Researchers at the Massachusetts Institute of Technology (MIT) have developed a method that, for the first time, produces detailed 3D objects on a nanoscale - by shrinking. To do this, they first position the components of the object in a larger pre-variant. Then they shrink the whole thing and create the desired object in nano format.

This so-called "implosion fabrication" is made possible by a special hydrogel made o…

2400 years old Shipwreck discovered in Black Sea

Archaeologists say the 2,400-year-old ship is so well preserved that even the mast and rowers' benches have survived for millennia.
ARCHAEOLOGISTS ARE HERALDING the discovery of an unusually intact ancient shipwreck, found more than a mile below the surface of the Black Sea off of the Bulgarian coast. The 2,400-year-old wooden vessel features elements of ship construction, including the mast and rowing benches, that until now have not been preserved on ships of this age.

An announcement of the discovery, made by the Black Sea Maritime Archaeology Project (MAP), first appeared in the Guardian. MAP has discovered more than 60 historic shipwrecks during a three-year survey of the Black Sea.

The 75-foot-long ship, documented by a Remote Operated Vehicle (ROV) equipped with cameras, appears similar to merchant vessels depicted on ancient Greek vases. A small piece of the wreck was raised and radiocarbon dated to around the fifth century B.C., a time when Greek city-states were frequen…

A ‘dark matter hurricane’ is storming past Earth

And it could help scientist detect the strange substance.

There’s a “dark matter hurricane” blowing through our corner of the Milky Way galaxy. Right this second, it’s passing over Earth. And this fast-moving stream could reveal major details about dark matter, a new study finds.

The dark matter is traveling in what is known as the S1 stream. Scientists think that streams like this one are the cosmic debris leftover when small galaxies stray too close to the Milky Way. Our gravitational forces tear the smaller galaxy apart, leaving behind a traveling, elliptical stream of stars, dark matter and other debris.

Dark matter hurricane

Dark matter is an elusive material that scientists think, if the Standard Model is correct, exists in large quantities throughout space. Scientists still don’t know what dark matter actually is — there are a number of leading theories, but no one knows for sure. But the S1 stream is predicted to be blowing dark matter past us at about 310 miles per second (50…

Alien sighting: Strange craft seen flying over New York is ‘proof' of UFOs

A BLACK UFO was spotted zooming across the skies of New York which has led some to state that it is ‘PROOF’ of aliens.

On December 6, onlookers were stunned to see a disc-like object travel at supersonic speeds above the state of New York. The sighting occurred over Utica, New York, and the craft appeared to be about 30 meters in length. The possibility of a passenger plane was ruled out as freeze frames appeared to show it has no wings and is pitch black

Some UFO hunters are claiming it is “proof” that aliens are here.

The video was uploaded to MUFON, a UFO hunting YouTube channel, which said: “We see what appears to be a black object in an oval form moving from right to left.

“At normal speed, it is easy to miss, but the submitter added a slow-motion clip which gives us a much better view.

“The object moves behind the clouds but is clearly seen in the cloud breaks. We took the still frame and moved in closer.”

Conspiracy theorists quickly picked up on the video, with Scott C Waring…

NASA probe OSIRIS-REx finds signs of water on nearby asteroid Bennu

NASA’s OSIRIS-REx spacecraft has discovered ingredients for water on a relatively nearby skyscraper-sized asteroid, a rocky acorn-shaped object that may hold clues to the origins of life on Earth, scientists said on Monday.

OSIRIS-REx, which flew last week within a scant 12 miles (19 km) of the asteroid Bennu some 1.4 million miles (2.25 million km) from Earth, found traces of hydrogen and oxygen molecules – part of the recipe for water and thus the potential for life – embedded in the asteroid’s rocky surface.

The probe, on a mission to return samples from the asteroid to Earth for study, was launched in 2016. Bennu, roughly a third of a mile wide (500 meters), orbits the sun at roughly the same distance as Earth. There is concern among scientists about the possibility of Bennu impacting Earth late in the 22nd century. “We have found the water-rich minerals from the early solar system, which is exactly the kind of sample we were going out there to find and ultimately bring back to E…

Chinese 'SUN' is three times hotter than our Sun

Chinese nuclear fusion scientists achieve temperatures three times hotter than the sun
The temperatures were roughly equal to a 'mid-sized thermo-nuclear explosion'

A nuclear reactor in China has created plasma at a temperature of 50 million Kelvins (49.999 million degrees Celsius or 90 million Fahrenheit) for 102 seconds.

The temperature is thought to be three times hotter than the core of the sun or “roughly the same as a mid-sized thermo-nuclear explosion,” according to the South China Morning Post.

The experiment was done in a machine called the Experimental Advanced Superconducting Tokamak (EAST).

It happened last week at the Institute of Plasma Physics at the Chinese Academy of Sciences in Jiangsu province.

The research team had aimed to maintain a plasma of 100 million Kelvins for over 1,000 seconds, nearly 17 minutes.

However, the length of time that the plasma was sustained and controlled remains significant, as this is one of the main obstacles to implementing nucle…

China Plans to Launch an 'Artificial Moon' to Light Up the Night Skies

China Plans to Launch an 'Artificial Moon' to Light Up the Night Skies.

The night skies might soon have company: Chinese scientists are planning to launch an artificial moon into orbit by 2020 to illuminate city streets after dark.

Scientists are hoping to hang the man-made moon above the city of Chengdu, the capital of China’s southwestern Sichuan province, according to a report in Chinese state media. The imitation celestial body — essentially an illuminated satellite — will bear a reflective coating to cast sunlight back to Earth, where it will supplement streetlights at night.

Scientists estimated that it could be eight times more luminous than the actual, original moon. It will also orbit much closer to Earth; about 500 km (310 miles) away, compared to the moon’s 380,000 km (236,000 miles).

But the ambitious plan still wouldn’t “light up the entire night sky,” Wu Chunfeng, chief of the Tian Fu New Area Science Society, told China Daily. “Its expected brightness, in the e…

Australian Police Warn That Apple Maps Could Get Someone Killed

"Police in Victoria, Australia warn that Apple's glitch-filled Maps app could get someone killed, after motorists looking for the Victorian city of Mildura were instead guided to a wilderness area. Relying on Apple Maps to navigate through rural Australia seems rather foolish but it has become common practice to rely on GPS navigation. Besides reverting to google maps, perhaps Apple should provide strong warnings to use other navigation sources if navigating to remote locations."

EARTHQUAKE WARNING: ‘Ground-splitting’ quake could hit TODAY warns forecaster

AN earthquake which has the potential to tear the ground OPEN could hit today, one self-proclaimed tremor mystic has claimed.

A planetary alignment over the last few days could cause a quake with a magnitude of 9 today, a conspiracy theorist has warned. Earth has become positioned between Venus and Uranus and the gravitational tug from each planet could cause a potentially civilisation ending earthquake. This is according to ‘New-age earthquake forecasting’ website Ditrianum, run by researcher Frank Hoogerbeets, who said an earthquake which is registers at 8.8 on the richter scale is predicted.

The gravitational pull of the celestial bodies either side of our planet could pull on Earth’s tectonic plates, according to the prediction.

Mr Hoogerbeets says that as the plates are tugged apart, they could cause earthquakes around the globe– and it could happen today.

Originally, the earthquake forecaster said the tremor will strike on December 9 or 10, but as yesterday passed without a meg…

Google launches AI-driven audio news feed

Google said Thursday it was launching a radio-style, on-demand audio news feed available on smart speakers, personalized with the help of artificial intelligence.

The technology giant said it had partnerships with more than a dozen news organizations to deliver an audio feed in the same manner as its smartphone news feed.

"This new experience will bring you an audio news playlist assembled in that moment, for you," Google product manager Liz Gannes said in a blog post.

"It starts with a briefing of top stories and updates on topics you care about, and extends into longer-form content that dives deeper into more stories."

Google Assistant, the AI program developed by the company, will manage the feed, allowing users to skip a story, go back or stop.

The project aims to transform audio news into a Netflix-like experience, available on demand with personalized recommendations.

"For the past century, radio has been a one-size-fits-all medium," Gannes wrote.

Brain implants might one day help paralyzed patients use tablets

Paralyzed people might one day be able to operate smartphones and tablets just by thinking about the actions they want to perform, with help from sensors implanted in their brains, a recent experiment suggests.

While previous experiments have had some success using brain sensors paired with customized computers to help paralyzed patients type up to eight words a minute, the current test focused on making it possible for these patients to use tablets and smartphones right out of the box without any special modifications, said lead author Dr. Jaimie Henderson of the Stanford University School of Medicine in California.

“We are still likely a number of years away from having a fully implantable, FDA-approved device that would be available for widespread use,” Henderson said by email. “However, I’m convinced that most of the technological hurdles have been solved and that we will one day in the near future see assistive devices that allow people with paralysis to control a computer using…

Listen to the Sound of Mars wind captured by NASA's Insight Lander

The sound of wind blowing across the surface of Mars has been recorded for the first time.

Nasa's latest spacecraft, the InSight lander, captured the "haunting low rumble" of Martian winds on 1 December, in a landmark moment for space exploration.

The InSight spacecraft landed on the Red Planet just ten days ago.

The Mars lander's sensors detected vibrations from the wind, which is thought to have been blowing at between 10 to 15 mph, northwest to southeast.

Nasa said that the direction of the wind was consistent with the direction of dust devil streaks which had been observed in the area.

"Capturing this audio was an unplanned treat," said Bruce Banerdt, the InSight team's principal investigator at Nasa.

"But one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves."

The wind vibrations were recorded in different ways on two of the spacecraft's sensors.

NASA asteroid WARNING: 360-FOOT-wide monster asteroid on 'Earth approach' TOMORROW

AN ENORMOUS asteroid large enough to wipe out an entire city will zip past the planet tomorrow afternoon, space agency NASA warned.

A dense, iron-packed asteroid as little as 40ft across (12m) has the power to wipe out buildings across a 3.6-mile radius (5.79km). And the bad news is one about three times as big is currently barreling towards the Earth at breakneck speeds of 14,808.5mph (6.62km per second). The giant space rock tracked by NASA, officially labelled Asteroid 2018 VX4, is expected to fly by the planet on Sunday, December 9. The space agency said the asteroid’s trajectory matches the parameters of a so-called Earth Close Approach.
The asteroid was dubbed a Near-Earth Object (NEO) as a result of its close brush with the Earth.

NASA’s scientists at the California-based Jet Propulsion Laboratory (JPL) believe it will be closest to Earth around 5.06pm GMT (UTC) tomorrow.
The astronomers estimate VX4 measures somewhere in the terrifying range of 157.5ft to 360.9ft (48m to 110m…
