Scientists Might Have Just Figured Out Where Nightmares Come From

A new study took the first steps toward figuring out which part of the brain is responsible for giving people nightmares and negative emotions during sleep.

Nightmare Factory

Nothing ruins a good night’s sleep like a dream about your teeth falling out or taking a calculus test while naked.

Thankfully, scientists are getting to the bottom of bad dreams, according to new research that tracks the neurological basis of nightmares.

Biological Culprit

The research, expected to be published Tuesday in the journal JNeurosci, tracks down which part of the brain is responsible for generating feelings of anger in sleeping people, according to Cosmos Magazine.

In the study, researchers woke people up when they were in the middle of what’s called REM sleep — short for Rapid Eye Movement — Lees verder

Scientists: Tech Is Giving Humanity a Shorter Attention Span

The collective attention span of humanity is getting shorter as the internet and technology bring us a near-constant supply of new information.

Pay Attention

A new study published in Nature Communications on Monday found that humanity’s collective attention span is getting shorter — a remarkable side effect likely attributable to technology.

“The world has become increasingly well connected in the past decades,” researcher Philipp Lorenz-Spreen said in a press release. “This means that content is increasing in volume, which exhausts our attention and our urge for ‘newness’ causes us to collectively switch between topics more rapidly.”

Top ‘Tags

The researchers cited Twitter hashtags as one example of this shortened attention span, noting that a hashtag that made it into the Lees verder

Saturn’s Moon Titan is Covered in Earth-Like Lakes

By analyzing data from Cassini spacecraft's last flyby in 2017, scientists found that Saturn's largest moon Titan has an entire lake district.

Alien Lake District

By analyzing data from NASA’s Cassini spacecraft’s last flyby in 2017, scientists found that Saturn’s largest moon Titan is covered with lakes similar to those found on Earth.

Precipitation refills some of the lakes once they drain over time, just like on Earth, confirming a long-standing theory about the moon’s geology. But there’s one obvious difference from Earth: Titan’s lakes are filled with  liquid hydrocarbons, including methane and ethane — very much unlike the fresh water found in Lake Michigan.

Titan Mesas

The new information about deep, miles-across lakes provides important insight into the nature of Titan’s geology — and how its north pole compares to Lees verder

Scientists Found a Chunk of a Comet Inside a Meteorite

In a rare find, scientists found what they think are fragments of a comet sealed away deep inside of a meteorite that struck Antarctica.

Space Turducken

Scientists just found a chunk of comet hiding inside of a rocky meteorite that fell to Earth.

Normally, comets burn up as they enter Earth’s atmosphere. In other words, according to Gizmodo, this cosmic calzone provided a protective shield around the comet fragments, giving scientists an valuable opportunity to study the origins of the solar system.

Small Samples

The meteorite in question is called LaPaz Icefield 02342, which was found in Antarctica in 2002. This new probe into the meteorite’s composition, published Monday in the journal ­Nature Astronomy, describes 100 micron-thick — the size of a thick human hair — carbon-rich segments Lees verder

After Failed Moon Landing, Israel Vows to Try Again

SpaceIL has announced plans to build Beresheet 2, a sequel to the spacecraft behind the company's first failed Moon landing.

Moving Forward

Beresheet may have crashed while attempting to touch down on the Moon on Thursday, but the company behind the failed Moon landing isn’t discouraged.

“We’re going to build a new spacecraft, we’re going to put it on the Moon, and we’re going to complete the mission,” SpaceIL founder Morris Kahn said in a video released just two days after the failed landing attempt.

Small Club

It’s not entirely surprising that SpaceIL isn’t ready to give up the dream of a Moon landing just yet.

Had Beresheet successfully completed its mission, it would have been the Lees verder

Chinese Scientists Aim to Generate Fusion Power by 2040

Chinese scientists want to achieve fusion power generation by the year 2040, according to Reuters.

Smashing Isotopes

It’s the ultimate energy goal: generating power from smashing together particles at extremely high pressure and temperatures — but without the threat of nuclear catastrophe.

There’s one big catch, though. Fusion energy has yet to achieve the milestone of actually generating more energy than is required to get the process going. But now, according to Reuters, are hoping to achieve fusion power generation by the year 2040.

Tokamak or Not Tokamak

China has already invested almost a billion dollars on a tokamak — a twisted-donut-shaped tank that can be used to capture the energy released by highly pressurized, hot hydrogen isotopes. And another $893 million Lees verder

5G Collars Let Cows Choose When They Want to Be Milked

A dairy farm has outfitted 50 cows with 5G-connected smart collars that allow the animals to be milked whenever they want.

Moo Juice

While humans wait for the age of 5G to take shape, the next generation of wireless connectivity is already changing the lives of 50 British cows.

A dairy farm at the government-funded Agricultural Engineering Precision Innovation Centre in Shepton Mallet, England, has fitted about a third of its cows with 5G-connected smart collars as part of a test for Cisco Systems — and the impact of this one trial could affect the future of agriculture.

Cash Cow

When a smart collar-fitted cow wants to be milked, it approaches a robotic milking system. This system knows how to latch Lees verder

Meteoroid Strikes Smash Water out of the Moon’s Surface

New NASA research shows that meteoroid strikes are digging up and vaporizing the Moon's already-scarce stores of surface water.

Lunar Water Cycle

The Moon is losing its water.

Beneath its dusty surface, our moon has a thin, lightly-hydrated layer. But new NASA research, published Monday in the journal Nature Geoscience, shows that it’s being gradually sucked dry by meteoroid impacts.

Vapor Waves

After a meteoroid smashes the water out to the Moon’s surface, the force of the impact coupled with the absence of an atmosphere causes it to vaporize, according to the research.

About a third of the vapor falls back down to the Moon’s surface, but the rest is kicked out into space — where one recent puff of vapor was detected by Lees verder

See the World’s Biggest Airplane Nail Its First Test Flight

The Stratolaunch, the world's biggest airplane, just completed its first test flight, putting us one step closer to cheaper launches into space.

Powerful Plane

An airplane with a wingspan greater than the length of a football field just flew for the first time — putting us one step closer to more affordable spaceflight.

The largest airplane in the world, the Stratolaunch, took off from Mojave Air and Space Port in Mojave, Calif., on Saturday for its first test flight. According to a news release, it reached a maximum speed of 304 kilometers per hour (189 miles per hour) over the course of the 2.5-hour-long flight, soaring as high as 17,000 feet before landing safely.

“The flight itself was smooth, which is exactly what you want a first Lees verder
