Thousands of crop varieties from 4 corners of the world depart for Arctic seed vault

At the end of January, more than 200,000 crop varieties from Asia, Africa, Latin America and the Middle East -- drawn from vast seed collections maintained by the Consultative Group on International Agricultural Research -- will be shipped to a remote island near the Arctic Circle, where they will be stored in the Svalbard Global Seed Vault, a facility capable of preserving their vitality for...

What gives us fingertip dexterity?

USC Viterbi School of Engineering biomedical engineer Francisco Valero-Cuevas is working to understand the biological, neurological and mechanical features of the human hand, features that enable dexterous manipulation and make it possible for a person to grasp and crack an egg, fasten a button or fumble with a cell phone to answer a call.

Zanzibar study paves way for mass co-delivery of three antiparasitic drugs

Findings from a new study in Zanzibar, published Jan. 23 in PLoS Neglected Tropical Diseases, pave the way for the World Health Organization to recommend the mass co-delivery of three antiparasitic drugs for the first time. The study shows the safety of delivering three drugs simultaneously -- ivermectin, albendazole and praziquantel -- in order to tackle three diseases, elephantiasis,...


A new view of drugs used to treat rheumatoid arthritis

Powerful drugs used to treat patients with rheumatoid arthritis have a profound, previously unrecognized effect on the immune system, breaking up molecular "training camps" for rogue cells that play an increasingly recognized role in autoimmune diseases like rheumatoid arthritis and lupus.

Economists help climate scientists to improve global warming forecasts

Climate scientists are collaborating with experts in economic theory to improve their forecasting models and assess more accurately the impact of rising atmospheric carbon dioxide levels. Although there is broad consensus that there will be a significant rise in average global temperature, there is great uncertainty over the extent of the change, and the implications for different regions.

Kaiser Permanente study shows link between caffeine and miscarriage

High doses of daily caffeine during pregnancy -- whether from coffee, tea, caffeinated soda or hot chocolate -- cause an increased risk of miscarriage, according a new study by the Kaiser Permanente Division of Research. The study controlled, for the first time, pregnancy-related symptoms of nausea, vomiting and caffeine aversion that tended to interfere with the determination of caffeine's true...

Nature publication on pain research

For people suffering from chronic illness, the spinal cord, which acts as a kind of filter for pain signals, is impaired. Led by ETH Zurich Professor Hanns Ulrich Zeilhofer, researchers have now found a way to restore it. Their results have been published in Nature.

New Kaiser Permanente study fortifies caffeine's link to miscarriage

A new study by Kaiser Permanente offers the strongest evidence to date linking caffeine consumption during pregnancy to miscarriage because it's the first study to thoroughly control for pregnancy-related caffeine aversion. Appearing in The American Journal of Obstetrics and Gynecology, the study of 1,063 pregnant women found that women who consumed 200 mg or more of caffeine per day doubled their...

Researcher transplants stem cells to try to save patients' legs

A Northwestern University researcher has launched the first US trial in which a purified form of subjects' own adult stem cells was transplanted into their leg muscles with severely blocked arteries to try to grow new small blood vessels and restore circulation. Severely blocked arteries in the leg can result in the breakdown of tissue, gangrene and amputation. This painful condition is called...

Researchers find relief for chronic pain

Researchers in the Department of Medicine and Department of Neurosciences at Mount Sinai School of Medicine have discovered that chronic pain can be successfully treated with novel targeted gene therapy. In an effort to find a more effective treatment for chronic pain, researchers at Mount Sinai developed a gene therapy technique that simulates the pain-killing effect of opiate drugs.

Rich nations' environmental footprints tread heavily on poor countries

UC Berkeley researchers have assessed the financial costs of environmental damage caused by human activities in high-, middle- and low-income nations, and where those costs fall. As expected, the rich nations disproportionately impact poor nations, but the results allows the researchers to estimate the total cost. Altogether, poor nations are burdened by a cost that exceeds what they owe the rich...

Saline nasal wash helps improve children's cold symptoms

A saline nasal wash solution made from processed seawater appears to improve nasal symptoms and may help prevent the recurrence of respiratory infections when used by children with the common cold, according to a report in the January issue of Archives of Otolaryngology, one of the JAMA/Archives journals.
