Will grassland soil weather a change?
There's more to an ecosystem than the visible plants and animals. The soil underneath is alive with vital microbes. They make sure nutrients from dead plant and animal material are broken down and made useable by other plants. This completes the process of nutrient cycling and carbon storage. Scientists are learning more about how important these microbes are. But how do changes in temperature and precipitation levels affect microbes? And will that affect carbon storage?

Number of severe algal blooms in Lake Erie to double, forecast says
By the latter half of this century, toxic algal blooms like the one that cut off drinking water to the city of Toledo in 2014 will no longer be the exception, but the norm, a study suggests.The findings hold implications for hundreds of coastal regions around the world where nutrient runoff and climate change intersect to make toxic algae a problem.

Study: Climate change rapidly warming world's lakes
Climate change is rapidly warming lakes around the world, threatening freshwater supplies and ecosystems, according to a study spanning six continents. The study is the largest of its kind and the first to use a combination of satellite temperature data and long-term ground measurements. A total of 235 lakes, representing more than half of the world's freshwater supply, were monitored for at least 25 years.

Land use may weaken amphibian's capacity to fight infection and disease
Man-made changes to the environment are linked to changes in the microbiome on cricket frogs' skin and antimicrobial peptide secretions through the skin, possibly weakening the animals' immune systems. The frog's population has drastically declined across its northern range since the 1970s.

Big moves in protein structure prediction and design
Reports in Nature this week on the modular construction of certain types of protein molecules are the latest in a series of advances in protein structure prediction and design. Because naturally occurring proteins act as nanomachines to carry out essential functions in living things, researchers are eager to custom-design and synthesize protein molecules that can perform critical tasks in medical, environmental and industrial arenas.

USF geologists focus on mineral for clues to beginning of biological life on earth
New research by University of South Florida geologists has found that in Earth's beginning, meteorites striking the planet to provide light may have carried within them an extraterrestrial mineral that, as it corroded in water on Earth, could have provided the essential chemical spark leading to the birth of biological life.

A molecular light switch?...Just add water
Researchers from Drexel University, The University of California at Berkeley, the University of Pennsylvania and Temple University uncovered a way to use water molecules to control ultraviolet light emitted from the inside of a complex oxide material. This discovery means the material could find use in chemical sensors, computing and information storage devices.

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.

Three miles high: Using drones to study high-altitude glaciers

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.
