To feed the future, we must mine the wealth of the world's seed banks today

ITHACA, N.Y. – With fewer than a dozen flowering plants out of 300,000 species accounting for 80 percent of humanity's caloric intake, people need to tap unused plants to feed the world in the near future, claims Cornell University plant geneticist Susan McCouch in the Comment feature of the July 4 issue of Nature.

Solitary lemurs avoid danger with a little help from the neighbors

Very little is known about the Sahamalaza sportive lemur (Lepilemur sahamalazensis), other than the fact it roosts during the day in rather open situations, such as tree holes, and therefore risks falling victim to predators from both the air and the ground.

In subglacial lake, surprising life goes on

BOWLING GREEN, O.—Lake Vostok, buried under a glacier in Antarctica, is so dark, deep and cold that scientists had considered it a possible model for other planets, a place where nothing could live.

Toronto team ID proteins key in stem cell production

TORONTO - A team of Toronto-based researchers may be one step closer to a 'recipe' for large-scale production of stem cells for use in research and therapy.

Induced pluripotent stem cells (iPSCs) can be of great value for medical research because they can flexibly develop into many different types of cells. However, producing these cells is challenging because the proteins that control their generation are largely unknown.

Tweet all about it -- Twitter can't replace newswires, study shows

News agencies continue to have an edge over Twitter in being first with the news, a study found.

Research into reporting of news events by Twitter and newswire services has found that while Twitter can sometimes break news before newswires, for major events there is little evidence that it can replace traditional news outlets.

Twitter's main benefits for news are bringing additional coverage of events, and for sharing news items of interest to niche audiences or with a short lifespan, such as local sports results.

Long-lived mice are less active

Risky behavior can lead to premature death – in humans. Anna Lindholm and her doctoral student Yannick Auclair investigated whether this also applies to animals by studying the behavior of 82 house mice. They recorded boldness, activity level, exploration tendency and energy intake of female and male house mice with two different allelic variants on chromosome 17, thereby testing predictions of "life-history theory" on how individuals invest optimally in growth and reproduction.

The balancing act of producing more food sustainably

A policy known as sustainable intensification could help meet the challenges of increasing demands for food from a growing global population, argues a team of scientists in an article in the journal Science.

New marker substance for cancer cells

Imaging techniques in cancer medicine provide far more than merely information on the scale and location of cancerous ulcers. There are modern methods that additionally characterise the tumour cells precisely, for instance by specific molecules they carry on their surface. Such additional information gives doctors key clues as to the precise cancer type and enables them to predict the probability that a patient will respond to a particular form of therapy.

New approaches to understanding infection may uncover novel therapies against influenza

The influenza virus' ability to mutate quickly has produced new, emerging strains that make drug discovery more critical than ever. For the first time, researchers at Seattle BioMed, along with collaborators at the University of California, San Diego School of Medicine, St. Jude Children's Research Hospital and the University of Washington, have mapped how critical molecules regulate both the induction and resolution of inflammation during flu infection. The results are published this month in the journal Cell.

Flu is an elusive foe

Grassland fencing threatens the survival of wild ungulates

Ungulates like Tibetan antelope, Kiang, wild yak, Przewalski's gazelle, Tibetan gazelle, Mongolian gazelle, roam on the steppes and grasslands of Asia, need large open habitats. For examples, once millions of Mongolian gazelles migrate to the Inner Mongolian steppe in winter and return to steppes in eastern Mongolia and Durian, Russia during the breeding in summer. Hundreds of thousands of Przewalski's gazelles also roam in the Alpine steppe in Qinghai lake drainage (Fig. 1). Those wild ungulates move freely on the grasslands are animal spectacles in Eurasia.

Unique shell design gives guillemot eggs an edge for living on the edge

Unique nano-structures on guillemot eggshells eggs enable them to survive precarious habitats, on exposed cliffs with no nest. A new study, to be presented at the Society for Experimental Biology meeting in Valencia on July 5, shows how these structures act as self-cleaning guardians of the eggs, preventing them from falling and protecting them from salt and guano exposure.

The team of researchers headed Dr Steven Portugal (Royal Veterinary College, University of London) discovered the nano-scale cone-like structures.

Octopus' blue blood allows them to rule the waves!

Worldwide colonization by octopods is in their blood! They manage to survive temperature habitats ranging from as low as -1.8°C to more than 30°C due to their ability to keep supplying oxygen to their body tissues. A new study, to be presented at the Society for Experimental Biology meeting on July 5, shows that a blue colored pigment, hemocyanin, in their blood, responsible for oxygen transport, crucially allows octopods to live in freezing temperatures.

Scientists discover ethnic differences in immune response to TB bacterium

The immune response to the bacterium that causes tuberculosis (TB) varies between patients of different ethnic origin, raising important implications for the development of tests to diagnose and monitor treatment for the disease, according to new research published today in the journal PLOS Pathogens.

No single origin for agriculture in the Fertile Crescent

A rich assemblage of fossils and artifacts in the foothills of the Zagros Mountains in Iran has revealed that the early inhabitants of the region began cultivating cereal grains for agriculture between 12,000 and 9,800 years ago. The discovery implies that the transition from foraging to farming took place at roughly the same time across the entire Fertile Crescent, not in a single core area of the "cradle of civilization," as previously thought.

University of East Anglia research reveals true cost of farming to UK economy

The British landscape is not being used to its best advantage according to a new report from environmental economists from the University of East Anglia (UEA).

Research published today in the journal Science shows that allowing land use to be determined purely by an agricultural market, which is distorted by multi-billion pound subsidies, will result in considerable financial and environmental costs to the public.

It shows that a shake-up in the way EU subsidies are given out could greatly improve the way UK farm land is managed.
