Changes to tiny blood vessels may help diagnose traumatic brain injuries

Health
April 30 (UPI) -- By finding changes to tiny blood vessels in the brains of people with traumatic injuries, researchers believe medical personnel could be able to make more precise diagnosis and treatment decisions.Researchers found that changes in the blood vessels may be linked to a range of cognitive symptoms after a traumatic brain injury, or TBI. The research, which was led by the University of Pennsylvania, was presented Friday at the American Academy of Neurology Annual Meeting and has not yet been published."The relationship between microvascular and structural injury in chronic TBI has been recognized for years, but underappreciated," Dr. Ramon Diaz-Arrastia, director of the Traumatic Brain Injury Clinical Research Center at the Perelman School of Medicine at Pennsylvania, said in...

Tiny invertebrates ride high winds across the desert, study shows

Science
March 13 (UPI) -- New research shows waterborne microinvertebrates can be dispersed across large deserts by high winds.Because these organisms form the base of food chains among arid habitats, the impact of climate change on their dispersal patterns could influence delicate ecosystems."These novel findings might have large implications for freshwater systems," Elizabeth J. Walsh, an ecologist at the University of Texas at El Paso, said in a news release.During a previous study of the Chihuahuan Desert in Mexico and West Texas, Walsh and her colleagues were surprised to find colonies of related microinvertebrates linking water basins separated by several hundred miles. Their discovery inspired them to find out how the tiny organisms disperse across such large regions."If they weren't being ...

The tiny treeshrew defies a pair of evolutionary rules

The tiny treeshrew defies a pair of evolutionary rules

Science
Jan. 5 (UPI) -- The tiny treeshrew is a breaker of evolutionary rules, specifically of the ecogeographical type.According to a new paper published this week in the journal Ecology and Evolution, the common treeshrew, Tupaia glis, flouts both the island rule and Bergmann's rule, a pair of rules describing expected geographical variation within a species.According to the island rule, specimens of small mammals living on islands tend to evolve larger bodies than their relatives on the mainland. Larger mammals tend to evolve smaller bodies on islands.Bergmann's rules describe the tendency for populations of a species to evolve larger bodies in colder climates, among higher latitudes, while populations closer to the equator, living in warmer climates, develop smaller bodies.Researchers measured...
Tiny ocean creatures can shred a plastic bag into 1.75 million pieces

Tiny ocean creatures can shred a plastic bag into 1.75 million pieces

Science
Dec. 8 (UPI) -- The ocean's miniature inhabitants can shred a small plastic bag -- the type used to hold groceries -- into 1.75 million microscopic fragments, according to a news study.When scientists from University of Plymouth in England fed a plastic bag to Orchestia gammarellus, a tiny species of amphipod abundant in the coastal waters of Northern Europe, they were surprised at the rate at which the trash was consumed and broken down.But while the amphipods broke down the plastic bag with tremendous speed and efficiency, they didn't exactly remove the trash from the environment. They simply turned one piece of plastic pollution into a lot of tiny pieces of plastic pollution -- 1.75 million microscopic fragments, to be exact.The findings -- detailed this week in the journal Marine Pollu...
