Researchers find mushrooms may hold clues to effect of carbon dioxide on lawns
Since the Industrial Revolution, the amount of carbon dioxide in the atmosphere has rapidly increased. Researchers at the University of New Hampshire set out to determine how rising carbon dioxide concentrations and different climates may alter vegetation like forests, croplands, and 40 million acres of American lawns. They found that the clues may lie in an unexpected source, mushrooms.

A big-picture look at the world's worst Ebola epidemic
An international effort to analyze the entire database of Ebola virus genomes from the 2013-2016 West African epidemic reveals insights into factors that sped or slowed the rampage and calls for using real-time sequencing and data-sharing to contain future viral disease outbreaks.

Treatment reverses signs of 2 degenerative brain diseases, ALS and ataxia, in mice
Scientists report a significant step toward combatting two degenerative brain diseases that chip away at an individual's ability to move, and think. A targeted therapy developed by investigators at University of Utah Health slows the progression of a condition in mice that mimics a rare disease called ataxia. In a parallel collaborative study led by researchers at Stanford University, a nearly identical treatment improves the health of mice that model Amyotrophic Lateral Sclerosis (ALS), commonly called Lou Gehrig's disease.

Virginia Tech scientists discover early dinosaur cousin had a surprising croc-like look
Teleocrater and other recently discovered dinosaur cousins show that these animals were widespread during the Triassic Period and lived in modern day Russia, India, and Brazil. Furthermore, these cousins existed and went extinct before dinosaurs even appeared in the fossil record.

Nuclear transfer of mitochondrial DNA in colon and rectal cancer
Patients with colon and rectal cancer have somatic insertions of mitochondrial DNA into the nuclear genomes of the cancer cells, UAB researchers report in the journal Genome Medicine. In a companion paper in Analytical Biochemistry, researchers describe a molecular tool to rapidly detect and analyze insertion of mitochondrial DNA into the genomes of cells.

'Neuron-reading' nanowires could accelerate development of drugs for neurological diseases
A team led by engineers at the University of California San Diego has developed nanowires that can record the electrical activity of neurons in fine detail. The new nanowire technology could one day serve as a platform to screen drugs for neurological diseases and could enable researchers to better understand how single cells communicate in large neuronal networks.

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

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.'

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.

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.
