Georgia Tech researchers demonstrate how the brain can handle so much data
Researchers at Georgia Tech discovered that humans can categorize data using less than 1 percent of the original information, and validated an algorithm to explain human learning -- a method that also can be used for machine learning, data analysis and computer vision.

East Antarctic Ice Sheet has stayed frozen for 14 million years, Penn team reports
In a new study in Scientific Reports, University of Pennsylvania researchers use an innovative technique to date one of Antarctica's ancient lake deposits. They found that the deposits have remained frozen for at least the last 14 million years, suggesting that the surrounding region, the East Antarctic Ice Sheet, or EAIS, has likewise remained intact.

Gamma rays from distant galaxy tell story of an escape
A flare of very high-energy gamma rays emitted from a galaxy halfway across the universe has put new bounds on the amount of background light in the universe and given astrophysicists clues to how and where such gamma rays are produced.

Three miles high: Using drones to study high-altitude glaciers
While some dream of the day that aerial drones deliver their online purchases, scientists are using the technology today to deliver data that was never available before. About 5,000 meters high in the Peruvian Andes, the scientists are mapping glaciers and wetlands in the Cordillera Blanca mountain range with 10-centimeter precision to gauge how climate change will affect the half-million local residents who rely in part on those glaciers for their water supply.

We infer a speaker's social identity from subtle linguistic cues
When we speak, we 'leak' information about our social identity through the nuanced language that we use to describe others, according to new research in Psychological Science, a journal of the Association for Psychological Science. This research shows that people can infer a speaker's social identity (e.g., political party affiliation) from how the speaker uses abstract or concrete terms to describe someone else's behavior.

Why the flu vaccine is less effective in the elderly
Around this time every year, the flu virus infects up to one-fifth of the US population and kills thousands of people, many of them elderly. A study published by Cell Press on Dec. 15, 2015, in Immunity now explains why the flu vaccine is less effective at protecting older individuals. More broadly, the findings reveal novel molecular signatures that could be used to predict which individuals are most likely to respond positively to vaccination.

Social media news consumers at higher risk of 'information bubbles,' IU study says
The first large-scale empirical analysis of online news-seeking behavior, conducted at Indiana University, has found that people who seek out news and information from social media are at higher risk of becoming trapped in a 'collective social bubble' compared to using search engines.

A well-preserved skeleton reveals the ecology and evolution of early carnivorous mammals
Prior to the rise of modern-day mammalian carnivores, North America was dominated by a now-extinct group of mammalian carnivores -- the hyaenodontids. While fossils of hyaenodontids are relatively common from the early Eocene Epoch -- between 50 million and 55 million years ago -- most of these are specimens of teeth. A new find of a nearly complete skeleton has allowed for a more detailed study of the ecology and evolutionary relationships of these early carnivores.

Precise method underlies sloppy madness of dog slurping
Using photography and laboratory simulations, researchers studied how dogs raise fluids into their mouths to drink. They discovered that sloppy-looking actions at the dog bowl are in fact high-speed, precisely timed movements that optimize a dogs' ability to acquire fluids.

Genes for age-related cognitive decline found in adult worm neurons
Researchers from Princeton University have identified genes important for age-related cognitive declines in memory in adult worm neurons, which had not been studied previously. The research, published today in the journal Nature, could eventually point the way toward therapies to extend life and enhance health in aging human populations.

Sea lions exposed to algal toxin show impaired spatial memory
California sea lions exposed to the algal toxin domoic acid can suffer brain damage that leads to significant deficits in spatial memory. The new findings suggest that chronic exposure to the toxin, produced by naturally occurring marine algae, causes impairments that are likely to affect sea lions' ability to navigate in their ocean habitat and survive in the wild.
