Existing cropland could feed 4 billion more
The world's croplands could feed 4 billion more people than they do now just by shifting from producing animal feed and biofuels to producing exclusively food for human consumption, according to new research from the Institute on the Environment at the University of Minnesota.

Geoscientists unearth mineral-making secrets potentially useful for new technologies
Proteins have gotten most of the attention in studies of how organic materials control the initial step of making the first tiny crystals that organisms use to build structures that help them move and protect themselves. Virginia Tech researchers have discovered that certain types of sugars, known as polysaccharides, may also control the timing and placement of minerals that animals use to produce hard structures.

As climate, disease links become clearer, study highlights need to forecast future shifts
Climate change is affecting the spread of infectious diseases worldwide, according to an international team of leading disease ecologists, with serious impacts to human health and biodiversity conservation. Writing in the journal Science, they propose that modeling the way disease systems respond to climate variables could help public health officials and environmental managers predict and mitigate the spread of lethal diseases.

Temperature alters population dynamics of common plant pests
Temperature-driven changes alter outbreak patterns of tea tortrix -- an insect pest -- and may shed light on how temperature influences whether insects emerge as cohesive cohorts or continuously, according to an international team of researchers. These findings have implications for both pest control and how climate change may alter infestations.

Climate strongly affects human conflict and violence worldwide, says study
Shifts in climate are strongly linked to human violence around the world, with even relatively minor departures from normal temperature or rainfall substantially increasing the risk of conflict in ancient times or today, according to a new study by researchers at the University of California, Berkeley, and Princeton University.

Arctic sea-ice loss has widespread effects on wildlife
How the Arctic wildlife and humans will be affected by the continued melting of Arctic sea ice is explored in a review article in the journal Science, by an international team of scientists. The article examines relationships among algae, plankton, whales, and terrestrial animals such as caribou, arctic foxes, and walrus; as well as the effects of human exploration of previously inaccessible parts of the region.

We each live in our own little world -- smellwise
There are some smells we all find revolting. But toward a handful of odors, different people display different sensitivities. A pair of studies identifies the genetic differences that underpin the differences in smell sensitivity. The researchers tested 200 people for their sensitivity to 10 different chemical compounds. They then searched through the subjects' genomes for areas of the DNA that differed between people who could smell a given compound and those who could not.

Robots strike fear in the hearts of fish
The latest in a series of experiments testing the ability of robots to influence live animals shows that bio-inspired robots can not only elicit fear in zebrafish, but that this reaction can be modulated by alcohol. These findings may pave the way for new methodologies for understanding anxiety and other emotions, as well as substances that modulate them.

Ecosystem service mapping and modelling -- new special issue shows big steps forward
Big steps forward toward practical application of the ecosystem services concept in science, policy and practice have been made recently and are presented in the new Special Issue "Mapping and Modelling Ecosystem Services" in the journal "Ecosystem Services". Modelling and mapping approaches aim at understanding stocks, demands and flows of ecosystem services on different spatial and temporal scales.

Could planting trees in the desert mitigate climate change?
As the world starts feeling the effects of increasing atmospheric carbon dioxide and consequent global temperature rise, researchers are looking for a Plan B to mitigate climate change. A group of German scientists has now come up with an environmentally friendly method that they say could do just that. The technique, dubbed carbon farming, consists in planting trees in arid regions on a large scale to capture CO2. They publish their study today in Earth System Dynamics, a journal of the European Geosciences Union.

Fat digestibility in pigs study looks at oils in soybeans, corn co-products
Pork producers need accurate information on the energy value of fat in feed ingredients to ensure that diets are formulated economically and in a way that maximizes pork fat quality. Researchers at the University of Illinois have determined the true ileal and total tract digestibility of fat in four corn co-products, as well as in full fat soybeans and corn oil.

NOAA-supported scientists find large Gulf dead zone, but smaller than predicted
NOAA-supported scientists found a large Gulf of Mexico oxygen-free or hypoxic 'dead' zone, but not as large as had been predicted. Measuring 5,840 square miles, an area the size of Connecticut, the 2013 Gulf dead zone indicates nutrients from the Mississippi River watershed, which drains 40 percent of the lower 48 states, are continuing to affect the nation's commercial and recreational marine resources in the Gulf.

Danes contract Salmonella infections abroad
In 2012 the number of Salmonella cases increased slightly after the record low incidence in 2011. Nearly half of the Danes who contracted Salmonella were infected abroad. Among people infected in Denmark, Danish pork and beef were estimated to be the major sources of Salmonella cases, while no cases could be attributed to Danish broiler meat.

Of bears and berries: Return of wolves aids grizzly bears in Yellowstone
A new study suggests that the return of wolves to Yellowstone National Park is beginning to bring back a key part of the diet of grizzly bears that has been missing for much of the past century -- berries that help bears put on fat before going into hibernation. The berries could aid bear survival and reproduction.
