New research system uses social media and other tools to gather, analyze expert opinions

Researchers have developed a new method of eliciting and analyzing opinions from a large group of experts and laypeople to aid complex decision-making, adapting online and social media technologies to lower the cost of such activities while expanding the types of people who can be queried.

Low-carbohydrate, high-protein diets may reduce both tumor growth rates and cancer risk

PHILADELPHIA — Eating a low-carbohydrate, high-protein diet may reduce the risk of cancer and slow the growth of tumors already present, according to a study published in Cancer Research, a journal of the American Association for Cancer Research.

The study was conducted in mice, but the scientists involved agree that the strong biological findings are definitive enough that an effect in humans can be considered.

E. coli bacteria more likely to develop resistance after exposure to low levels of antibiotics

New Rochelle, NY, June 14, 2011—E. coli bacteria exposed to three common antibiotics were more likely to develop antibiotic resistance following low-level antibiotic exposure than after exposure to high concentrations that would kill the bacteria or inhibit their growth, according to a timely article in Microbial Drug Resistance, a peer-reviewed journal published by Mary Ann Liebert, Inc. The article is available free online at www.liebertpub.com/mdr

New cell type offers immunology hope

A team of Australian scientists has discovered a new type of cell in the immune system.

The new cell type, a kind of white blood cell, belongs to a family of T-cells that play a critical role in protection against infectious disease.

Their findings could ultimately lead to the development of novel drugs that strengthen the immune response against particular types of infectious organisms.

It is also potentially significant for many other important diseases including allergies, cancer and coronary artery disease.

ESC calls for research into vulnerable plaques

Sophia Antipolis, France: Tuesday 14 June : The European Society of Cardiology (ESC) Working Group of Atherosclerosis and Vascular Biology has published a position paper to raise the profile of vulnerable plaques and the need for greater use of therapies to promote plaque stabilisation. The position paper, published online today in Thrombosis and Haemostasis, is also calling for more research into the causes of plaque rupture, and for the development of better diagnostics and treatments.

Nanotubes could pose health risk to production line staff, study suggests

Tiny fibres used to strengthen everyday products such as bicycle frames and hockey sticks could pose health hazards to those involved in their manufacture.

Certain types of carbon nanotubes – cylindrical molecules about one-thousandth of the width of a human hair – could cause cancer in the lining of the lung, University of Edinburgh researchers have found.

New study supports Darwin's hypothesis on competition between species

A new study provides support for Darwin's hypothesis that the struggle for existence is stronger between more closely related species than those distantly related. While ecologists generally accept the premise, this new study contains the strongest direct experimental evidence yet to support its validity.

Sleep loss in early childhood may contribute to the development of ADHD symptoms

DARIEN, IL – Short sleep duration may contribute to the development or worsening of hyperactivity and inattention during early childhood, suggests a research abstract that will be presented Tuesday, June 14, in Minneapolis, Minn., at SLEEP 2011, the 25th Anniversary Meeting of the Associated Professional Sleep Societies LLC (APSS).

East Africa and Middle East seek plan to keep animal diseases from disrupting livestock trade

This press release is available in Arabic.

DUBAI (14 June 2011)—With increased trade in livestock products offering a possible antidote to high food prices, livestock experts from the Middle East and 12 African countries are meeting this week in Dubai to develop a strategy that eliminates the need to impose devastating bans on livestock imports from the Horn of Africa, as prevention against the spread of Rift Valley fever. The strategy should expedite the flow of livestock products while increasing safety of the overall livestock trade in the region.

Scientists find deadly amphibian disease in the last disease-free region of central America

Smithsonian scientists have confirmed that chytridiomycosis, a rapidly spreading amphibian disease, has reached a site near Panama's Darien region. This was the last area in the entire mountainous neotropics to be free of the disease. This is troubling news for the Panama Amphibian Rescue and Conservation Project, a consortium of nine U.S. and Panamanian institutions that aims to rescue 20 species of frogs in imminent danger of extinction.

A scientific breakthrough at the IRCM could help understand certain cancers

Montréal, June 13, 2011 – A scientific breakthrough by researchers at the Institut de recherches cliniques de Montréal (IRCM) will be published tomorrow in Developmental Cell, a scientific journal of the Cell Press group. Led by Dr. Frédéric Charron, the team of scientists discovered a new requirement for the proper functioning of the Sonic Hedgehog protein.

More genetic diseases linked to potentially fixable gene-splicing problems

PROVIDENCE, R.I. [Brown University] — A new Brown University computer analysis that predicts the effect of genetic mutations on how the body splices mRNA indicates as many as a third of disease-related mutations may be linked to splicing problems — more than double the proportion previously thought.

Scripps Research team sheds new light on how blood clots form

Scripps Research Institute scientists have discovered new elements of the blood clot-formation process. The findings could lead to better drugs for preventing heart attacks and other clot-related conditions.

The work, which was published by the Journal of Clinical Investigation in an advance, online edition June 13, 2011, helps to establish a new model of clot formation.

Genome offers clue to functions of destructive wheat fungus

WEST LAFAYETTE, Ind. - One of the world's most destructive wheat pathogens is genetically built to evade detection before infecting its host, according to a study that mapped the genome of the fungus.

Science explains ancient copper artifacts

EVANSTON, Ill. --- Northwestern University researchers ditched many of their high-tech tools and turned to large stones, fire and some old-fashioned elbow grease to recreate techniques used by Native American coppersmiths who lived more than 600 years ago.

This prehistoric approach to metalworking was part of a metallurgical analysis of copper artifacts left behind by the Mississippians of the Cahokia Mounds, who lived in southeastern Illinois from 700 until 1400 A.D. The study was published in the Journal of Archaeological Science in May.
