Study in mice moves researchers closer to staph vaccine

Health
Dec. 24 (UPI) -- Staph infections pose a serious health threat -- particularly since they are often resistant to many currently available antibiotics. Researchers at Washington University School of Medicine in St. Louis think they may be one step closer to developing a vaccine that can prevent the spread of these deadly bugs. Their findings were published Tuesday in the Journal of Clinical Investigation. "Across the globe, staph infections have become a pervasive health threat because of increasing antibiotic resistance," senior investigator Juliane Bubeck Wardenburg, director of the Division of Pediatric Critical Care at Washington University, said in a press release. "Despite the medical community's best efforts, the superbug has shown a consistent ability to elude treatment" Staph bac...

Researchers map brain’s opioid response in mice

Health
Dec. 24 (UPI) -- Researchers may be closer to solving some of the mysteries of the brain processes involved in opioid addiction, thanks to a new imaging approach tested in mice. In experiments performed at the Karolinska Institutet in Stockholm, scientists were able to visualize the organization of different opioid islands in the striatum, the inner part of the brain that regulates rewards, motivation, impulses and motor function. They published the so-called spatio-molecular map Tuesday in the journal Cell Reports. "Our map forms the basis for a new understanding of the brain's probably most important network for decision-making," lead author Konstantinos Meletis, associate professor of neuroscience at Karolinska Institutet, said in a statement. "It may contribute to an increased unders...

Muscular ‘mighty mice’ and sensitive robot sent to space station

Technology
A nest of muscle-bound mice, a sensitive robot and 120,000 "beneficial" roundworms have arrived at the International Space Station.The assortment was delivered to station commander Luca Parmitano on Sunday as part of a three-tonne SpaceX shipment of "science, supplies and hardware", including Christmas treats for its six crew members. Forty mice - all adolescent females with black fur - will be used for a muscle and bone experiment in space, NASA said - with eight of these deemed "mighty mice", genetically engineered to have twice the normal muscle mass. The Rodent Research-19 project will examine muscle and bone loss in space - a serious health issue for astronauts - and look at aiding recovery following return to Earth.It could also support the development of therapies "for a wide rang...

The Dragon capsule also is delivering holiday goodies for the six station residents. NASA's Kenny Todd isn't giving any hints, but said, “Santa's sleigh, I think, is certified for the vacuum of space.” The recycled capsule should arrive Sunday. The Falcon rocket blasted off from Cape Canaveral a day la

Lucky lab mice get to live in a 'smart house'

Science
March 7 (UPI) -- Scientists have developed a "smart house" for mice, which will allow scientists to observe the behavior of tested mice while limiting disturbance levels. Researchers are constantly working to ensure external factors and outside influence, like the presence of a peering scientists, aren't influencing test results. Designers of the new digs claim their "Autonomouse" system will improve the welfare of lab mice, while ensuring greater consistency across different tests results. "We want to understand how the brain works, and for that we need to measure behavior," Andreas Schaefer, neuroscience researcher at the Francis Crick Institute in England, said in a news release. "In mice, this is normally done in a very manual and laborious way, which limits the amount of questions w...
