Some black holes erase your past

Physicists insist on determinism: your past and present determine your future uniquely, per Einstein's equations of general relativity. They call this strong cosmic censorship. A mathematician found some types of black holes -- charged, non-rotating objects in an expanding universe -- that allow an observer inside the black hole to travel across a horizon into a place where the past is obliterated and there are an infinite number of possible futures for every initial state.

In a first, tiny diamond anvils trigger chemical reactions by squeezing

Added: 21.02.2018 13:19 | 0 views | 0 comments


Scientists have turned the smallest possible bits of diamond and other super-hard specks into 'molecular anvils' that squeeze and twist molecules until chemical bonds break and atoms exchange electrons. These are the first such chemical reactions triggered by mechanical pressure alone, and researchers say the method offers a new way to do chemistry at the molecular level that is greener, more efficient and much more precise.

Amateur astronomer captures rare first light from massive exploding star

Added: 21.02.2018 13:18 | 0 views | 0 comments

First light from a supernova is hard to capture; no one can predict where and when a star will explode. An amateur astronomer has now captured on film this first light, emitted when the exploding core hits the star's outer layers: shock breakout. Subsequent observations by astronomers using the Lick and Keck observatories helped identify it as a Type IIb supernova that slimmed down from 20 to 5 solar masses before exploding.

Astronomers reveal a new high resolution map of the magnetic field lines in gas and dust swirling around the supermassive black hole at the center of our Galaxy. The team created the map, which is the first of its kind, using the CanariCam infrared camera attached to the Gran Telescopio Canarias sited on the island of La Palma.

Fancy a jellyfish chip?

A researcher became intrigued by jellyfish when he bit into the marine delicacy and experienced an unexpected crunch; he decided he wanted to 'understand the transformation from soft gel to this crunchy thing.' Scientists have now combined their expertise in biophysics and biochemistry to gain a better understanding of how food preparation affects jellyfish from the inside out.

'Ultramassive' black holes discovered in far-off galaxies

Added: 21.02.2018 11:28 | 0 views | 0 comments

#zrodlo

Thanks to data collected by NASA’s Chandra X-ray telescope on galaxies up to 3.5 billion light years away from Earth, an international team of astrophysicists was able to detect what is likely to be the most massive black holes ever discovered in the universe. The team’s calculations showed that these “ultramassive” black holes are growing faster than the stars in their respective galaxies.

Fake news ‘vaccine’: online game may ‘inoculate’ by simulating propaganda tactics

Added: 21.02.2018 6:25 | 0 views | 0 comments


A new online game puts players in the shoes of an aspiring propagandist to give the public a taste of the techniques and motivations behind the spread of disinformation -- potentially 'inoculating' them against the influence of so-called fake news in the process.

Jymmin: How a combination of exercise and music helps us feel less pain

Added: 21.02.2018 5:27 | 1 views | 0 comments

#zrodlo

Pain is essential for survival. However, it could also slow rehabilitation, or could become a distinct disorder. How strongly we feel it depends on our individual pain threshold. Scientists have discovered that this threshold can be increased by a new fitness method called Jymmin. It combines working out on gym machines with free musical improvisation -- and makes us less sensitive towards physical discomfort.

Scientists have developed robotic crystals that walk slowly like an inchworm and roll 20,000 times faster than its walking speed. These autonomously moving, organic crystals have great potential as material for soft robots in the future.

Helping in spite of risk: Ants perform risk-averse sanitary care of infectious nest mates

Ants care for their sick nest mates in different ways, depending on their own immune status. When they themselves are susceptible to dangerous superinfections, they use a different method to care for sick colony members compared to ants that are not susceptible, thus protecting themselves from infection.

When it comes to our brains, there's no such thing as normal

Added: 20.02.2018 19:29 | 0 views | 0 comments

#zrodlo

There's nothing wrong with being a little weird. Because we think of psychological disorders on a continuum, we may worry when our own ways of thinking and behaving don't match up with our idealized notion of health. But some variability can be healthy and even adaptive, say researchers, even though it can also complicate attempts to identify standardized markers of pathology.

'Brain on a chip' reveals how the brain folds

Added: 20.02.2018 16:13 | 0 views | 0 comments

#zrodlo

Our brains are wrinkled like walnuts by the time we are born. Babies born without these wrinkles -- called smooth brain syndrome -- suffer from severe developmental deficiencies and their life expectancy is markedly reduced. Now researchers have developed a method for growing tiny 'brains on chips' from human cells that enabled them to track the physical and biological mechanisms underlying the wrinkling process.

Many chemical processes run so fast that they are only roughly understood. To clarify these processes, researchers have now developed a methodology with a resolution of quintillionths of a second. The new technology stands to help better understand processes like photosynthesis and develop faster computer chips.
