    Antibiotics Use Linked to Type-1 Diabetes in Mice: Study

    Antibiotics are powerful medicines that destroy bacteria, and they’re lifesavers when an infection caused by dangerous microbes needs to be overtaken. A new study in mice published in the journal Nature Microbiology finds a link between type-1 diabetes and antibiotic use. Type-1 diabetes, an autoimmune disease diagnosed mostly in childhood, has a genetic influence, but it has risen rapidly since World War II and is affecting increasingly younger children.

    500-Year-Old Hidden Images Revealed in Mexican 'Manuscript'

    Storytelling images on a deer-hide "manuscript" from Mexico have been seen for the first time in 500 years, thanks to sophisticated scanning technology that penetrated layers of chalk and plaster. This "codex," a type of book-like text, originated in the part of Mexico that is now Oaxaca, and is one of only 20 surviving codices that were made in the Americas prior to the arrival of Europeans. Other Mexican codices recovered from this period contained colorful pictographs — images that represent words or phrases — which have been translated as descriptions of alliances, wars, rituals and genealogies, according to the study authors.

    A lengthening crack is threatening to cause an Antarctic ice shelf to collapse

    A large rift is widening across an increasingly fragile Antarctic ice shelf, scientists found. About 10 to 12 percent of the Larsen C Ice Shelf is expected to break off during such an event, leaving the larger ice shelf even more vulnerable to melting from increasing air and ocean temperatures. The iceberg and ice shelf melting would not, however, increase sea levels, since the ice is already resting in the ocean, like an ice cube in a glass.

    Remembering D.A. Henderson

    D.A. Henderson, an American public-health official who led the international campaign to eradicate smallpox in one of the greatest scientific endeavors of the 20th century, died on Friday. Henderson’s death was announced Saturday by the University of Pittsburgh Medical Center, where he taught as a public-health professor. When Henderson, then a 39-year-old epidemiologist, became the first chief of the World Health Organization’s smallpox-eradication unit in 1967, the virus killed an estimated two million people every year on three continents.

    Breadwinner Men May Have More Money, But Poorer Health

    Men who earn more money than their wives may be rolling in the bucks, but they tend to have poor health and heightened anxiety, new research shows. Researchers analyzed surveys from 9,000 young married men and women in the United States taken annually over a 15-year period, and evaluated each participant's response on income, health and psychological wellness. The findings suggest that men who are primary breadwinners — and who, in essence, fulfill the culturally held expectation that husbands should bring home more money than their wives — are actually worse off than men who earn salaries that are more equal to those of their wives.

    Scientists: Puffin chicks starving with less food available

    Atlantic puffin chicks on Machias Seal Island in the Gulf of Maine have had the worst breeding season ever recorded, with the majority of chicks starving to death in burrows, scientists said. A drop in the puffins' food supply is to blame, said Tony Diamond, director of the Atlantic Laboratory for Avian Research at the University of New Brunswick. In a typical year, 60 percent of the puffin nests with eggs produce chicks that fly off the nest, and this year, the success rate was 12 percent, the Portland Press Herald (http://bit.ly/2bCwkaf) reported.

    10 companies hiring people to work on driverless cars

    With Tesla unveiling its Master Plan 2.0 that includes a fleet of shared, driverless vehicles, Ford's announcement that it will mass produce fully-autonomous cars by 2021, and Uber's plan to use driverless cars in Pittsburgh by the end of August, there has never been more enthusiasm for the potential of self-driving cars. But, while Tesla's Autopilot and other driver assistance systems have come a long way in advancing the technology behind autonomous driving, there are still some big technical hurdles to overcome to get these vehicles ready for the public—and that's fantastic news for tech jobs. If you're a software developer, engineer, roboticist, or designer, now has never been a better time

    Nearly Everything the Media Tell You About Sexual Orientation and Gender Identity Is Wrong

    A major new report, published today in the journal The New Atlantis, challenges the leading narratives that the media has pushed regarding sexual orientation and gender identity. Co-authored by two of the nation’s leading scholars on mental health and sexuality, the 143-page report discusses over 200 peer-reviewed studies in the biological, psychological, and social sciences, painstakingly documenting what scientific research shows and does not show about sexuality and gender. “The belief that sexual orientation is an innate, biologically fixed human property—that people are ‘born that way’—is not supported by scientific evidence. “Likewise, the belief that gender identity is an innate, fixed human property independent of biological sex—so that a person might be a ‘man trapped in a woman’s body’ or ‘a woman trapped in a man’s body’—is not supported by scientific evidence.

    A rare, nearly complete T. Rex skull just arrived in Seattle

    SEATTLE - A four-foot long skull of a Tyrannosaurus Rex arrived arrived at the Burke Museum Thursday morning, and could well prove to be one of the best-preserved skull specimens ever seen, according to museum scientists.  The T. rex was found in northern Montana, part of the Hell Creek Formation where many dinosaur fossils have been found. The skull, protected in a plaster cast reinforced with wood, is not the only bone found from this giant meat-eating dinosaur. Scientists at the Burke Museum estimate they have 20% of the skeleton so far, including vertebrae, ribs, and the hips.  Researchers are optimistic that many of the other bones are still buried in the hillside awaiting excavation, but

    This Tree Started Growing During the Viking Age

    The tree, dubbed "Adonis" by the scientists who discovered it, is a Bosnian pine (Pinus heldreichii) that took root in A.D. 941, high in the Pindus mountains of Greece. "It is quite remarkable that this large, complex and impressive organism has survived so long in such an inhospitable environment, in a land that has been civilized for over 3,000 years," Paul J. Krusic, a dendrochronologist at Stockholm University in Sweden, and the leader of the expedition that found the tree, said in a statement. Researchers first discovered the tree during a research trip run by the Navarino Environmental Observatory (NEO), which was analyzing tree rings for evidence of the region's past climate.

    German Greens call for end to coal power in 20 years

    Germany's opposition Green party unveiled Monday a 10-point plan to end electricity generation from coal within 20 years, a key plank of its campaign heading into next year's general elections. "We aim to introduce the end of the coal era in Germany, irreversibly and reliably in the coming parliamentary term," running to 2021, Green lawmakers wrote in the proposal, a copy of which was obtained by AFP. As the smallest party represented in parliament, the Greens have been mooted as a potential kingmaker to Chancellor Angela Merkel's conservatives after the general election expected in September or October 2017.

    A lost spacecraft is talking to NASA again after nearly 2 years in the void

    Somewhere on the other side of the sun, almost directly opposite to Earth, a 9-year-old NASA spacecraft has drifted aimlessly through the void, unable to establish contact with our planet, since Oct. 1, 2014. Each STEREO spacecraft launched in 2006 and began circling the sun in slightly different yet Earth-like orbits. This also allowed NASA to get amazing 3D views of solar flares, coronal mass ejections, huge loops of plasma, and other solar activity.

    Creeping slime is coating hallowed monuments

    It sounds like the stuff of horror films: a creeping black slime that can't be killed. But experts say a real-life microbial invasion is coating some of the nation's most important monuments in black. The National Park Service earlier this month reported the "biofilm" has befouled the Jefferson Memorial, particularly its "gleaming white rotunda," and appears on the Washington and Lincoln Memorials and on tombstones in the Congressional Cemetery. But the mysterious substance—"part algae, part bacteria, part fungi," the Washington Post reports—isn’t unique to the Washington, DC, area. Biofilm has slimed sites around the globe, from Egypt to Italy to the Angkor Wat temples in Cambodia, per the NPS.

    Glass Half Empty? Why You May Be Less Optimistic Than You Think

    The studies that have suggested that people tend to be inherently optimistic may have had flawed methods of measuring this so-called "optimism bias," the researchers said. Optimism bias, for example, is thought to occur in people who are told their statistical chance of experiencing a bad life event such as cancer. "Previous studies, which have used flawed methodologies to claim that people are optimistic across all situations and that this bias is 'normal,' are now in serious doubt," Adam Harris, a psychologist at University College London and co-author of the study, said in a statement.

    Deadly Case of 'Bagpipe Lung' Highlights Danger of Fungal Infections

    One man's fatal lung infection highlights a rare danger that musicians may face: getting sick from fungi growing within their instruments, according to a recent report of the case. The 61-year-old man developed what his doctors in England described as "bagpipe lung," and died just a month after he was hospitalized for his infection, according to the case report, published today (Aug. 22) in the journal Thorax. The man had previously been diagnosed with a lung condition called hypersensitivity pneumonitis, in 2009, the doctors who treated him wrote.

    A Tiny Jellyfish Relative Just Shut Down Yellowstone River

    On August 12, Montana officials realized that the mountain whitefish of Yellowstone River were dying en masse. They sent corpses off for testing and got grave news in return: The fish had proliferative kidney disease—the work of a highly contagious parasite that kills between 20 and 100 percent of infected hosts. Tens of thousands of whitefish were already dead, and trout were starting to fall. Humans can spread the parasite from one water source to another. So, on the morning of August 19, Montana Fish, Wildlife and Parks closed a 183-mile stretch of the Yellowstone River, banning all fishing, swimming, floating, and boating. “We recognize that this decision will have a significant impact on

    World's largest pyramid is hidden in a mountain in Mexico

    When Hernan Cortez and his Spanish army marched into Cholula in present-day Mexico nearly 500 years ago, they were greeted by a peaceful people prone to building pyramids instead of stockpiles of weapons. Those people and their pyramids fell, and fast, with 10% of the local population murdered in a day as their pyramids were torched into oblivion. But as legend has it, one mud-brick pyramid was hidden, perhaps accidentally by vegetation, and was for centuries mistaken for a mountain, until locals began to construct an insane asylum in 1910. That's when they discovered the largest monument ever constructed anywhere in the world. Tlachihualtepetl, or the Great Pyramid of Cholula, stands more than
