Scientists found a way to communicate with people while they're asleep and dreaming

Roos Koole/Getty Images In a new study, scientists found they could communicate with people who are lucid dreaming. Lucid dreaming is when a person is aware they are dreaming. The dreamers could answer yes-or-no questions and solve basic math problems while asleep. Visit the Business section of Insider for more stories. Scientists have identified a new phenomenon they describe as "interactive dreaming" - when people experiencing deep sleep and lucid dreams are able to follow instructions,...

The white dots in this image are not stars or galaxies - they're black holes

A zoomed-in image of a space map showing 25,000 black holes. Each white dot is a supermassive black hole in its own galaxy. LOFAR/LOL Survey Astronomers in Europe compiled the most detailed map of black holes to date. Their map of the northern sky shows 25,000 white dots, each representing a supermassive black hole.  Visit the Business section of Insider for more stories. The image above may look like a fairly normal picture of the night sky, but what you're looking at is a lot more specia...

Astronomers have discovered the earliest known supermassive black hole at the center of an ancient, faraway galaxy

An artist's impression of quasar J0313-1806. NOIRLab/NSF/AURA/J. da Silva Astronomers have discovered the earliest known supermassive black hole at the center of a bright, active galaxy called a quasar, 13 billion light-years away. The quasar is unexpectedly well-developed for how soon it appears after the Big Bang. The supermassive black hole at its center is far older and more massive than scientists thought possible, suggesting a new way that black holes could form. Visit Business I...

A species of bacteria survived on the outside of the International Space Station for a full year

The International Space Station. NASA A species of bacterium, Deinococcus radiodurans, survived for a year on the outside of the International Space Station.  It endured microgravity, harsh ultraviolet radiation, and temperatures near absolute zero. Scientists found that the bacteria developed more small bumps than its counterparts on Earth. Visit Business Insider's homepage for more stories. A year in space is no walk in the park. Just ask Scott Kelly, the American astronaut who spent a y...

Platypus fur glows greenish-blue under UV light, new research found

An adult male platypus named Millsom is carried by his keeper at an animal sanctuary in Melbourne, May 8, 2008. Mick Tsikas/Reuters Scientists discovered that platypus fur glows greenish-blue under ultraviolet light.  It's the first time biofluorescence has been discovered in monotremes, one of three living types of mammals. The discovery may indicate that mammals evolved biofluorescent fur more than 150 million years ago. This glowing fur could help nocturnal mammals camouflage, or it cou...

NASA scientists discovered a 'very weird' molecule in the atmosphere of Saturn's moon Titan. It could point to alien life.

This near-infrared, color mosaic from NASA's Cassini spacecraft shows the sun glinting off of Titan's north polar seas. NASA/JPL-Caltech/Univ. Arizona/Univ. Idaho NASA astronomers discovered a "very weird little molecule" called cyclopropenylidene in the atmosphere of Saturn's moon Titan. Scientists think alien life could survive in Titan's underground salty ocean. This molecule could serve as a stepping stone to more complex molecules that play important roles in sustaining life. ...

Yellowstone's Old Faithful geyser went quiet 800 years ago. New research suggests it could happen again within the next century.

Visitors wearing masks leave after an eruption of the Old Faithful geyser in Yellowstone National Park, Wyoming, May 18, 2020. National Park Service/Jacob W. Frank/Handout via Reuters Old Faithful geyser in Wyoming's Yellowstone National Park erupts regularly every 90 minutes or so. A new study found that its eruption frequency has changed over time, and stopped completely for a few decades 800 years ago. The pause came during a period of global warming that resulted in long droughts in Ye...

A striking new photo of Jupiter shows the Great Red Spot is shrinking – and other storms are growing

This photo of Jupiter, captured by NASA's Hubble Space Telescope on August 25, 2020, provides astronomers with new information about the planet's turbulent weather patterns. NASA, ESA, STScI, A. Simon (Goddard Space Flight Center), and M.H. Wong (University of California, Berkeley) and the OPAL team The Hubble Space Telescope took a striking new photo of Jupiter that shows how the planet's weather patterns have evolved. The gas giant's most famous storm – its Great Red Spot – has b...

Groundbreaking new energy storage device charges up in just 20 seconds

A new aqueous storage device can be fully charged in a mere 20 seconds. Korea Advanced Institute of Science and Technology (KAIST) and Kangwon National University scientists developed the device suited for portable electronics, with KAIST emphasizing in a statement that their device is both safe and environmentally friendly. Aqueous storage devices are less flammable than today’s lithium batteries, and could be cheaper too, according to ScienceAlert, but limitations have held scientists back. ...
