Most YouTube climate change videos ‘oppose the consensus view’

The majority of YouTube videos about the climate crisis oppose the scientific consensus and “hijack” technical terms to make them appear credible, a new study has found. Researchers have warned that users searching the video site to learn about climate science may be exposed to content that goes against mainstream scientific belief. Dr Joachim Allgaier Read more about Most YouTube climate change videos ‘oppose the consensus view’[…]

In a Lab Accident, Scientists Create the First-Ever Permanently Magnetic Liquid

Using a technique to 3D-print liquids, the scientists created millimeter-size droplets from water, oil and iron-oxides. The liquid droplets keep their shape because some of the iron-oxide particles bind with surfactants — substances that reduce the surface tension of a liquid. The surfactants create a film around the liquid water, with some iron-oxide particles creating Read more about In a Lab Accident, Scientists Create the First-Ever Permanently Magnetic Liquid[…]

‘No doubt left’ about scientific consensus on global warming, say experts

The scientific consensus that humans are causing global warming is likely to have passed 99%, according to the lead author of the most authoritative study on the subject, and could rise further after separate research that clears up some of the remaining doubts. Three studies published in Nature and Nature Geoscience use extensive historical data Read more about ‘No doubt left’ about scientific consensus on global warming, say experts[…]

Scientists 3D-print human skin and bone for Mars astronauts

Scientists from the University Hospital of Dresden Technical University in Germany bio-printed skin and bone samples upside down to help determine if the method could be used in a low-gravity environment. It worked. ESA released videos of the printing in action. The skin sample was printed using human blood plasma as a “bio ink.” The researchers added Read more about Scientists 3D-print human skin and bone for Mars astronauts[…]

Study finds that parental ‘memory’ is inherited across generations

“While neuronally encoded behavior isn’t thought to be inherited across generations, we wanted to test the possibility that environmentally triggered modifications could allow ‘memory’ of parental experiences to be inherited,” explains Julianna “Lita” Bozler, a Ph.D. candidate in the Bosco Lab at the Geisel School of Medicine, who served as lead author on the study. Read more about Study finds that parental ‘memory’ is inherited across generations[…]

Indoor carbon dioxide levels could be a health hazard, scientists warn

Indoor levels of carbon dioxide could be clouding our thinking and may even pose a wider danger to human health, researchers say. While air pollutants such as tiny particles and nitrogen oxides have been the subject of much research, there have been far fewer studies looking into the health impact of CO2. However, the authors Read more about Indoor carbon dioxide levels could be a health hazard, scientists warn[…]

Ancient life awakens amid thawing ice caps and permafrost

Researchers in a warming Arctic are discovering organisms, frozen and presumed dead for millennia, that can bear life anew. These ice age zombies range from simple bacteria to multicellular animals, and their endurance is prompting scientists to revise their understanding of what it means to survive. “You wouldn’t assume that anything buried for hundreds of Read more about Ancient life awakens amid thawing ice caps and permafrost[…]

ISS is home to super-tough molds that laugh in the face of deadly radiation

Mold spores commonly found aboard the International Space Station (ISS) turn out to be radiation resistant enough to survive 200 times the X-ray dose needed to kill a human being.

New property of light discovered, plus recently discovered properties you probably didn’t know about

Scientists have long known about such properties of light as wavelength. More recently, researchers have found that light can also be twisted, a property called angular momentum. Beams with highly structured angular momentum are said to have orbital angular momentum (OAM), and are called vortex beams. They appear as a helix surrounding a common center, Read more about New property of light discovered, plus recently discovered properties you probably didn’t know about[…]

Laboratory Black Hole Shows Stephen Hawking Was Right, – wait they make black holes in labs now?!

Physicists have confirmed predictions of Stephen Hawking’s namesake theory of black holes using a black hole they constructed in their lab, according to a new paper. This black hole isn’t like the black holes out in space, where gravity creates a region of spacetime so warped that light can’t escape. Instead, the researchers built a Read more about Laboratory Black Hole Shows Stephen Hawking Was Right, – wait they make black holes in labs now?![…]
