CWRU researchers discover 3 new species of extinct South American marsupials
The discovery of three extinct species and new insights to a fourth indicates a little-known family of marsupials, the Palaeothentidae, was diverse and existed over a wide range of South America as recent as 13 million years ago. Fossils of the new species were found at Quebrada Honda, a high elevation fossil site in southern Bolivia, and are among the youngest known palaeothentid fossils.

Physicists discover hidden aspects of electrodynamics
Radio waves, microwaves and even light itself are all made of electric and magnetic fields. The classical theory of electromagnetism was completed in the 1860s by James Clerk Maxwell. At the time, Maxwell's theory was revolutionary, and provided a unified framework to understand electricity, magnetism and optics. Now, new research led by LSU Department of Physics & Astronomy Assistant Professor Ivan Agullo, with colleagues from the Universidad de Valencia, Spain, advances knowledge of this theory. Their recent discoveries have been published in Physical Review Letters.

Wiring of the 'little brain' linked to multiple forms of mental illness
Nearly half of people with one mental illness also experience another mental illness at the same time. This is leading researchers to shift their focus away from individual disorders and search instead for common mechanisms or risk factors that might cause all types of mental disorders. Duke researchers have now linked specific differences in the cerebellum and pons to many types of mental illness.

Who are you on social media? New research examines norms of online personas
According to the Pew Research center, the majority of adults on the internet have more than one social networking profile on sites like Facebook, Twitter, and LinkedIn. Although the core purpose of these sites are similar -- to digitally connect with peers and loved ones -- new research conducted by researchers in Penn State's College of Information Sciences and Technology and King's College in London, England, found users often adopt different personas unique to each social network.

Did you catch that? Robot's speed of light communication could protect you from danger
If you were monitoring a security camera and saw someone set down a backpack and walk away, you might pay special attention -- especially if you had been alerted to watch that particular person. According to Cornell University researchers, this might be a job robots could do better than humans, by communicating at the speed of light and sharing images.

Precision chronology sheds new light on the origins of Mongolia's nomadic horse culture
According to new research, nomadic horse culture -- famously associated with Genghis Khan and his Mongol hordes -- can trace its roots back more than 3,000 years in the eastern Eurasian Steppes, in the territory of modern Mongolia.

So you think you can secure your mobile phone with a fingerprint?
No two people are believed to have identical fingerprints, but researchers have found that partial similarities between prints are common enough that the fingerprint-based security systems used in electronic devices can be more vulnerable than previously thought. The vulnerability lies in the fact that fingerprint-based authentication systems feature small sensors that store partial fingerprints. The researchers found there could be enough similarities among different people's partial prints that one could create a 'MasterPrint.'

New method could deliver DNA-based vaccines in pill form
An oral-delivery method for DNA-based vaccinations and cancer-treating gene therapies would help make the medications more widely available. Nebraska researchers combined a corn-based protein and a derivative from shrimp shells to create an ingestible pill form for engineered genes and virus-derived DNA.

Ant agricultural revolution began 30 million years ago in dry, desert-like climate
Millions of years before humans discovered agriculture, ants were farming fungus beneath the surface of the Earth. By tracing their evolutionary history, scientists at the Smithsonian's National Museum of Natural History have learned about a key transition in their agricultural evolution. This transition allowed the ants to achieve higher levels of complexity in farming, rivaling the agricultural practices of humans. Scientists report that this transition likely occurred when farming ants began living in dry climates.

Social media tools can reinforce stigma and stereotypes
Researchers have developed new software to analyze social media comments, and used this tool in a recent study to better understand attitudes that can cause emotional pain, stigmatize people and reinforce stereotypes. In comments about Alzheimer's disease and other forms of dementia they found that 51 percent of tweets by private users of Twitter accounts contained stigma.

UMass Amherst tick testing lab joins national ecology tracking project
The LMZ at UMass Amherst earned a two-year, renewable contract for up to $112,000 per year to test several thousand ticks for six bacterial and one protozoan pathogen using DNA-based assays. UMass Amherst microbiology professor and LMZ director Stephen Rich says these tests will detect the pathogens that cause Lyme disease, Anaplasmosis and Babesiosis, among others.

Forget sponges: The earliest animals were marine jellies
One of the longest-running controversies in evolutionary biology has been, 'What was the oldest branch of the animal family tree?' Was it the sponges, as had long been thought, or was it the delicate marine predators called comb jellies? A powerful new method has been devised to settle contentious phylogenetic tree-of-life issues like this and it comes down squarely on the side of comb jellies.

As fins evolve to help fish swim, so does the nervous system
The sensory system in fish fins evolves in parallel to fin shape and mechanics, and is specifically tuned to work with the fish's swimming behavior, according to new research from the University of Chicago. The researchers found these parallels across a wide range of fish species, suggesting that it may occur in other animals as well.

Fish social lives may be key to saving coral reefs
Fish provide a critical service for coral reefs by eating algae that can kill coral and dominate reefs if left unchecked. A UC Davis study, which analyzed the social feeding behavior of reef fish, suggests that overfishing not only removes vital algae-eaters, but it may cause remaining fish to eat less.

North America's freshwater lakes are getting saltier
North America's freshwater lakes are getting saltier due to development and exposure to road salt. A study of 371 lakes published today in the Proceedings of the National Academy of Sciences reports that many Midwestern and Northeastern lakes are experiencing increasing chloride trends, with some 44 percent of lakes sampled in these regions undergoing long-term salinization. The study is the first large-scale analysis of chloride trends in freshwater lakes.

400 million years of a stable relationship
