The bioprinted ‘play dough’ capable of cell and protein transfer

Scientists have developed a new technique allowing the bioprinting at ambient temperatures of a strong paste similar to ‘play dough’ capable of incorporating protein-releasing microspheres. The scientists demonstrated that the bioprinted material, in the form of a micro-particle paste capable of being injected via a syringe, could sustain stresses and strains similar to cancellous bone — the ‘spongy’ bone tissue typically found at the end of long bones.

Infection with Wolbachia bacteria curbs fighting among fruit flies

Male fruit flies infected with the bacterium, Wolbachia, are less aggressive than those not infected, according to research published in the July Applied and Environmental Microbiology, a journal of the American Society for Microbiology. This is the first time bacteria have been shown to influence aggression, said corresponding author Jeremy C. Brownlie, Ph.D., Deputy Head, School of Natural Sciences, Griffith University, Brisbane, Australia.

Intrusiveness of old emotional memories can be reduced by computer game play procedure

Unwanted, intrusive visual memories are a core feature of stress- and trauma-related clinical disorders such as posttraumatic stress disorder, but they can also crop up in everyday life. New research shows that even once intrusive memories have been laid down, playing a visually demanding computer game after reactivating the memories may reduce their occurrence over time. The findings are published in Psychological Science, a journal of the Association for Psychological Science.

Federal report: Polar bears in peril due to global warming

FILE - In this June 15, 2014 file photo, a polar bear dries off after taking a swim in the Chukchi Sea in Alaska. About a third of the world's polar bears could be in imminent danger from greenhouse gas emissions in as soon as a decade, a U.S. government report shows. The U.S. Geological Survey, the Interior Department's research arm, said updated scientific models don't bode well for polar bear populations across the world, especially in Alaska, the only state in the nation with the white bears. (Brian Battaile/U.S. Geological Survey via AP, File)ANCHORAGE, Alaska (AP) — Polar bears are at risk of dying off if humans don't reverse the trend of global warming, a blunt U.S. government report filed Thursday said.

Genome study reveals how the woolly mammoth thrived in the cold

An undated illustration shows a group of woolly mammoths, the huge Ice Age mammalsBy Will Dunham WASHINGTON (Reuters) – Woolly mammoths spent their lives enduring extreme Arctic conditions including frigid temperatures, an arid environment and the relentless cycle of dark winters and bright summers. An exhaustive genetic analysis of these bygone Ice Age giants and their living cousins, Asian and African elephants, has revealed a slew of genetic adaptations that enabled woolly mammoths to thrive for eons in such adverse circumstances. The study, published on Thursday in the journal Cell Reports, compared the genomes of two mammoths whose remains were found in permafrost in northeastern Siberia, one 18,500 years old and the other 60,000 years old, with genomes of three Asian elephants and one African elephant.

Lawsuit filed against U.S. over protections for rare wolf

A handout photo of an endangered gray wolf(Reuters) – A coalition of environmental groups filed a lawsuit on Thursday against U.S. wildlife officials arguing that the government's management plan for the endangered Mexican gray wolf, one of the most imperiled mammals in North America, does not go far enough. The Western Environmental Law Center filed the suit on behalf of several organizations in a federal Arizona court, alleging the U.S. Fish and Wildlife Service's plans for the wolves violate the Endangered Species Act and other laws. "Unfortunately, politics supplants wildlife biology in key parts of the USFWS Mexican gray wolf plan," attorney John Mellgren of the Western Environmental Law Center said in a statement.

Black Hole ‘Wakes Up’ After 26-Year Slumber

Black Hole 'Wakes Up' After 26-Year SlumberAfter taking a 26-year nap, a waking black hole released a burst of X-rays that lit up astronomical observatories on June 15 — and it's still making a ruckus today. Astronomers identified the revived black hole as an "X-ray nova" — a sudden increase in star luminosity — coming from a binary system in the constellation Cygnus. The burst was first caught by NASA's Swift satellite, and then by a Japanese experiment on the International Space Station, called Monitor of All-sky X-ray Image (MAXI).

Mass Shootings Are Contagious

Mass shootings spawn subsequent mass shootings, new research finds. The researchers discovered statistical “clusters” of shootings in which four or more people die, the standard definition of a mass shooting. School shootings also cluster, said study researcher Sherry Towers, a professor of mathematical and computational modeling at Arizona State University.

Domo Arigato, Mr. Pluto: Rock Band Styx Visits New Horizons Team

Domo Arigato, Mr. Pluto: Rock Band Styx Visits New Horizons TeamAs NASA's New Horizons spacecraft sails away to Pluto, one bunch of musicians is particularly intrigued by its journey: Styx, the rock band that shares a name with Pluto's smallest moon. Members of the iconic rock group recently met with the space probe's NASA team at the mission's headquarters at the Johns Hopkins University Applied Physics Laboratory (APL) in Maryland. All of Pluto's moons rock, of course, but perhaps the most hardcore is Styx, which was spotted by the Hubble Space Telescope in 2012.

Seahorse’s Amazing Tail Could Inspire Better Robots

Seahorse's Amazing Tail Could Inspire Better RobotsSlinky snake robots could get a better grip when climbing, thanks to new research on how a seahorse's tail works, according to a new study. "Human engineers tend to build things that are stiff so they can be controlled easily," study co-author Ross Hatton, an assistant professor in the College of Engineering at Oregon State University, said in a statement. In particular, seahorses have square (rather than round) bony plates that surround the "backbone" of their tails.

10,000 Monitored for Ebola in US Over Fall & Winter

More than 10,000 people in the United States were monitored for symptoms of Ebola this past fall and winter, according to a new report from the Centers for Disease Control and Prevention. In late October, the CDC recommended that everyone in the United States who had possibly been exposed to Ebola — including people returning from an Ebola-affected country, as well as those who cared for Ebola patients here — be monitored for 21 days after their last exposure for symptoms of the disease. The people being monitored took their own temperatures twice a day, and reported their health status to a public health official at least once daily.

Plague Evolution: How a Mild Stomach Bug Became a Worldwide Killer

Plague Evolution: How a Mild Stomach Bug Became a Worldwide KillerThe Black Death — the dreaded plague that killed millions of people during the Middle Ages — only reached pandemic status after the bacteria that cause it acquired two pivotal mutations, a new study finds. With the first of those mutations, ancient strains of plague bacteria (Yersinia pestis) gained the ability to cause pneumonic plague — a respiratory form of the disease that spreads easily when people infected with it sneeze around others, researchers found. Only later did the plague genome acquire the second mutation, which gave it the ability to cause the fast-killing disease known today as bubonic plague, the researchers said in their study, published online today (June 30) in the journal Nature Communications.
