For some, things like fluttering fingers and soft voices can trigger "brain tingles", a pleasurable scalp prickling that cascades soothingly down the body. But researching ASMR and misophonia together could yield new insights into the mechanisms that underlie both, says Agnieszka Janik McErlean, a senior lecturer in psychology at Bath Spa University in England. McErlean's resulting lit search turned up hundreds of YouTube channels dedicated to stimulating ASMR but not a single scientific paper. Experts still aren't sure what causes it or how best to treat suffering patients, but even the small body of existing research provided McErlean with more reference material than her dive into ASMR.

EDITOR'S LETTER IN JAPAN, THERE'S A method of repairing shattered pottery called kintsugi, in which artisans rejoin shards with gold-laced epoxy. Once the repair is complete, the shimmering veins not only increase the value of the mended object, they also hold on to the beauty of its past life as it continues anew. Legend holds that the technique arose in the 15th century, when a shogun was displeased with a first attempt at fixing his favorite tea bowl. [Extracted from the article]

But in 2018, worried about the amount of sheer junk like cling wrap coming in, China banned all rubbish imports save for 99.5 percent pure plastic.

FEATURES In early 2020, Alexis Triplett watched the news coming out of China, her gaze set on a TV inside her cell in La Vista Correctional Facility in Pueblo, Colorado. Just before Colorado's outbreak, La Vista housed 694 male and female inmates, slightly below its capacity of 707; even so, seven other women shared Triplett's cell. Staff gave inmates masks that would do their job but that Triplett didn't find particularly comfortable. Staff then grouped inmates into fixed cohorts - of eight women, in Triplett's case - so that if one person became ill, they'd expose only each other. [Extracted from the article]

FEATURES IN THE EARLY 1990s, Kinari Webb took a year off college to join a Harvard researcher studying orangutans in INODNESIA'S rainforested GUNUNG PALUNG National Park. As she continued her work in the Bornean forests in the intervening decades, Webb would discover another consequence of the tree-chopping economy: Pervasive illegal logging can also threaten public health. The three threads of ASRI's program - health care, organic farming, and tree planting - interweave in a single conservation economy. Already ASRI has more than 100 employees in Indonesia (twice that number in tree-planting season), and Webb has recently established a similar program in Madagascar and is launching another one in the Amazon.

FEATURES Collages by Marryam Moma popsci.com Winter 2020 PG 61 AROUND 11 IN THE MORNING ON a 90-degree day in June 2020, a few dozen people walk across a field in Louisiana's St. James Parish on the west bank of the Mississippi River. The Juneteenth visitors are supporters of a coalition called RISE St. James, which formed in 2018 to oppose the Formosa complex on the grounds that it might harm community health. Formosa hired archaeologists to examine the property in 2018; they concluded that little remained of those sites and suggested the fence around the Buena Vista plot. The activists accused the agency of wrongly granting Formosa its permits, partly on the grounds that the company failed to properly identify possible burials on the complex and inform the community.

FEATURES DAN INMAN HAD ANTICIPATED THIS MOMENT FOR MONTHS. But league racers employed the same techniques that Inman had used in amateur matches - and more advanced ones, like slightly bending their axles to make their cars zippier. To pick an oil to use on his axles, Inman purchased a bunch from multiple online derby shops, set up his own league-regulation aluminum track, and created an elaborate two-car test. In his rookie year, Inman regularly lost to Brian Crane, a veteran who had risen through the ranks to become one of the league's most formidable competitors. [Extracted from the article]

This spiffy little terrier is volunteer number one on day number one of an ambitious project launched by Harvard University evolutionary neuroscientist Erin Hecht to answer basic questions about what dogs do and why they do it. In fact, research out of the Wolf Science Center has found that in some situations, these wild animals are actually more tolerant than dogs: Given food to share, dogs keep their distance from one another. In one study, pairs of wolves or dogs must cooperate to retrieve a piece of meat; wolves work together effectively, but dogs were "abysmally bad", says investigator Sarah Marshall-Pescini. When she tested wolf-human and dog-human cooperation partners, the pattern became clearer. [Extracted from the article]

Warinner was there to solve a mystery: Despite the dairy diversity she saw, an estimated 95 percent of Mongolians are, genetically speaking, lactose intolerant. But, Warinner says, direct evidence of long-ago dairy consumption was absent - until ancient calculus let her harvest it straight from the mouths of the dead. Warinner's initial hypothesis was that the Mongolian herders - past and present - were using lactose- eating microbes to break down their many varieties of dairy, making it digestible. In summer 2020, Warinner's team will return to Khatgal and other rural regions to collect mouth swabs and fecal specimens from herders, the last phase in cataloging the traditional Mongolian micro biome.
