A study published January 3 in Nature Communications provides new evidence that, rather than releasing seismic tensions in the crust, the 2015 quake likely loaded the surrounding region for an even more destructive mega-earthquake, which could clock in at magnitudes of 8.5 or higher. Earthquakes in the Himalaya, however, present a curious puzzle: “When you look at the historical seismicity, it looks like you don’t have enough earthquakes to balance the energy that is accumulating because of this loading,” says Caltech’s Jean-Philippe Avouac, coauthor of the new study. Each moderate quake therefore builds up energy, eventually leading to a megaquake that cracks through to the surface once every 500 or 600 years, finally relaxing the region’s built-up strain. Only two Himalayan earthquakes in the past 500 years have definitely ruptured to the surface, one in 1934 and another in 1950, explains Roger Bilham, lead author of the 2017 study.

Building on work done by physicist Amos Ori two decades prior, and armed with her strong computational skills, Mallary built a computer model that would capture most of the essential physical effects on a spacecraft, or any large object, falling into a large, rotating black hole like Sagittarius A*. What she discovered is that under all conditions an object falling into a rotating black hole would not experience infinitely large effects upon passage through the hole’s so-called inner horizon singularity. Mallary also discovered a feature that was not fully appreciated before: the fact that the effects of the singularity in the context of a rotating black hole would result in rapidly increasing cycles of stretching and squeezing on the spacecraft. Mallary’s approach of using a computer simulation to examine the effects of a black hole on an object is very common in the field of black hole physics.

But the work of image examiners has never had a strong scientific foundation, and the FBI’s endorsement of the unit’s findings as trial evidence troubles many experts and raises anew questions about the role of the FBI Laboratory as a standard-setter in forensic science. The work of image examiners is a type of pattern analysis, a category of forensic science that has repeatedly led to misidentifications at the FBI and other crime laboratories. The problems with the FBI’s photo comparison work plague other subjective types of forensic science, such as fingerprint analysis, microscopic hair fiber examination and handwriting analysis, said Itiel Dror, a neuroscientist who trains U.S. law enforcement on cognitive bias in crime laboratories.

Prosecutors had presented jurors with days of circumstantial evidence against the ex-convict, Wilbert McKreith, before Vorder Bruegge took the stand.

In 2015, the FDA revised its controversial ban, announcing that gay and bisexual men can donate blood if they abstain from sex with men for a full year—a condition heterosexual donors and LGBTQ women don’t have to meet. Contextualized in a science-centric show that explores how disease affects New York City’s communities, Blood Mirror highlights how “there’s essentially an FDA-imposed quarantine on gay people,” Eagles says. In his artist’s statement for the sculpture, he cites a 2014 UCLA Williams Institute study, which estimated that lifting the ban on men who have sex with men would increase the total annual blood supply in the US by two to four percent, and could be used to help save the lives of more than a million people. New work by Jordan Eagles, based off a 1994 HULK comic called “In the Shadow of AIDS,” and paired with blood from an HIV+ undetectable donor and a donor on PrEP.

When heated, propylene glycol produces a smoke-like vapor, which means this ingredient is responsible for the sick clouds that you create while smoking your Juul. Needless to say, nicotine is the ingredient responsible for everyone becoming addicted to Juuling: One recently published government survey found that 1.3 million more teens vaped in 2018 than the year prior, and the popularity of Juul certainly seems to be responsible. 6) Benzoic Acid: Benzoic acid is widely used as a food preservative; however, it can also be used to increase the potency of nicotine without adding even more nicotine — which is exactly why it can be found in Juul pods. Unfortunately, some studies have found the benzoic acid found in Juul pods can be carcinogenic; however, others have refuted this claim.

Tactics from foam rollers to compression tights to ice baths have become popular among all athletes, whether they be weekend warriors or elite competitors. Because of its popularity and perhaps simplicity, ice baths are among the most studied muscle recovery methods. In one study, researchers had a group of “recreationally active” men cycle for a short period, then had them undergo one of three recovery conditions: An ice bath, a warm bath (as a control), and a bath with a common skin cleanser that participants were told was a newly developed “recovery oil”. Prior to beginning the treatment, when asked, participants in the ice bath group and the “recovery oil” placebo group both believed, to a similar degree, in the integrity of the recovery methods they were about to receive. A study done that compares the two treatments—a traditional ice bath to whole body cryotherapy—found that a chilly soak reduces blood flow and tissue temperature better than the cryotherapy.

The oldest known periodic table in world has been discovered at the University of St Andrews. Dated back to 1885, the table was created only 16 years after Russian chemist Dmitri Mendeleev introduced the concept in 1869. According to Eric Scerri, an expert on the history of the periodic table based at the University of California, Los Angeles, the chart can be dated back to a time period between 1879 and 1886. “The discovery of the world’s oldest classroom periodic table at the University of St Andrews is remarkable,” says David O’Hagan, recent ex-head of chemistry at the University of St Andrews, in a press statement. “The table will be available for research and display at the University and we have a number of events planned in 2019, which has been designated international year of the periodic table by the United Nations, to coincide with the 150th anniversary of the table’s creation by Dmitri Mendeleev.”

Böhme and her colleagues conducted a series of three tests on different groups of experiment participants to learn about what’s going on in the nervous system and the brain during self touch and touch from others. In the first test, they placed subjects in an MRI and found that fewer areas of the brain were activated, and at a lower intensity, during self touch than when experimenters touched the subjects. In the third test, experimenters placed an electrode on subjects’ thumbs and used it to track how quickly the brain processes information from self touch and touch by others. They found that the perception of self touch was lower priority for the brains of their test subjects than the perception of touch by other people. This study demonstrated that test subjects’ brains clearly understood the difference between self-touch and touch by others, and weighted those two experiences differently.

The growing popularity of such “digital detoxes” is encouraged by a slew of negative findings about the effects of technology use, alongside claims that such action can help reduce stress and help people become more “present” and compassionate. But frequent use of technology and social media isn’t a problem in itself. People have always been concerned about almost every mass-adopted technology invented, and social media and smartphones are no different. When it comes to digital detoxes, there is unlikely to be anything seriously wrong with stepping away from technology for the majority of people. In fact, seeing as there’s little evidence to suggest that technology is inherently bad, it might be that digital detoxes have no problem to solve in the first place.

This suggests surface ice is simply melting as global temperatures rise, causing gushing rivers of meltwater to flow into the ocean and push up sea levels. If all of Greenland’s vast ice sheet, 3km thick in places, was to melt, global sea levels would rise by seven meters, or more than 20ft, drowning most coastal settlements. The fate of Greenland’s huge glaciers in the south-east and north-west has long been viewed as a key factor in global sea level rise but the Ohio State-led research suggests the ice fields of the island’s south-west may prove an unexpectedly large source of meltwater. Arctic ice loss has tripled since the 1980s, with melting in places such as Greenland and Alaska providing the greatest instigator of sea level rise while destabilizing the very ground underneath 4 million people’s feet. The world’s largest expanse of ice is now losing about 219bn tonnes of ice a year, a trajectory that would contribute more than 25cm to total global sea level rise by 2070.
