Threatened frogs palmed off as forests disappear

Oil palm plantations in Malaysia are causing threatened forest frogs to disappear, paving the way for common species to move in on their turf, scientists have revealed.

The study, carried out by the Zoological Society of London (ZSL) describes how forests converted to palm oil plantations are causing threatened forest dwelling frogs to vanish, resulting in an overall loss of habitat that is important for the conservation of threatened frog species in the region.

Middle-aged women commonly become ill with stress

In four out of ten cases, long-term stress suffered by women leads to some form of physical complaint. This is shown by a study of 1,500 women carried out at the Sahlgrenska Academy, University of Gothenburg, Sweden.

Within the Population Study of Women in Gothenburg, researchers at the University of Gothenburg's Sahlgrenska Academy have followed around 1,500 women since the late 1960s.

Modern dragons in danger-- the relentless exploitation of Asian giant lizards revealed

A new study reveals that Southeast Asian monitor lizards, representing the world's largest lizards, are harvested and traded for their skins and as pets in intangible volumes despite existing legislation – and much of this trade is illegal. Germany plays a major role in the international trade with live reptiles. On June 8th, 2013, the world's largest reptile fair will take place in Germany (Hamm, Westphalia).

A healthy start

The European Perinatal Health Report released by the EURO-PERISTAT project is the most comprehensive report on the health and care of pregnant women and babies in Europe and brings together data from 2010 from 26 European Union member states, plus Iceland, Norway and Switzerland. EURO-PERISTAT takes a new approach to health reporting.

Mutations in susceptibility genes common in younger African American women with breast cancer

A high percentage of African-American women with breast cancer who were evaluated at a university cancer-risk clinic were found to carry inherited genetic mutations that increase their risk for breast cancer.

The finding suggests that inherited mutations may be more common than anticipated in this understudied group and may partially explain why African-Americans more often develop early onset and "triple-negative" breast cancer, an aggressive and difficult-to-treat form of the disease.

Study suggests that night work may impair glucose tolerance

DARIEN, IL – A new study suggests that night work may impair glucose tolerance, supporting a causal role of night work in the increased risk of Type 2 diabetes among shift workers.

Results show that peak glucose levels were 16 percent higher during one night of simulated shift work, compared with one day of a simulated daytime work schedule. Compared with the daytime protocol, insulin levels during the night shift protocol were 40 to 50 percent higher at 80 minutes and 90 minutes after a meal.

RET rearrangement a new oncogene and potential target in lung cancer

In results presented at ASCO 2013, a University of Colorado Cancer Center study provides important details for a recently identified driver and target in lung adenocarcinoma: rearrangement of the gene RET. The finding is an important step along a trajectory like that which led to FDA approval of the drug crizotinib, which targets a somewhat similar rearrangement in the ALK gene.

Patients with type 2 diabetes or hypertension must be evaluated for sleep apnea

Baltimore - The American Academy of Sleep Medicine (AASM) is advising anyone with Type 2 diabetes or hypertension to be evaluated for sleep apnea by a board-certified sleep medicine physician. The recommendation comes as the group of international clinicians and researchers meets in Baltimore for SLEEP 2013, the foremost gathering of sleep experts annually.

Dartmouth researchers test safety of Nivolumab in kidney cancer

(Lebanon, NH, 5/24/13) — Researchers at Dartmouth-Hitchcock Norris Cotton Cancer Center will present a poster on a phase I clinical trial of Nivolumab, a PD-1 receptor blocking antibody, being used in combination with other drugs in patients with metastatic renal cell carcinoma (mRCC) at the ASCO Annual Meeting on June 3, 2013.

Metastatic renal cell carcinoma or kidney cancer is the seventh most common cancer, leading to approximately 116,000 deaths annually worldwide. In roughly one-quarter of those with mRCC, the cancer has already spread or metastasized at diagnosis.

Cancer drug shortages hit 83 percent of US oncologists

CHICAGO – Eighty-three percent of cancer doctors report that they've faced oncology drug shortages, and of those, nearly all say that their patients' treatment has been impacted, according to a study from researchers at the Abramson Cancer Center and the Perelman School of Medicine at the University of Pennsylvania that will be presented today at the 2013 annual meeting of the American Society of Clinical Oncology (Abstract #CRA6510).

Harvard development expert: Agricultural innovation offers only path to feed Africa and the world

The world can only meet its future food needs through innovation, including the use of agricultural biotechnology, a Harvard development specialist said today.

Since their commercial debut in the mid-1990s, genetically-designed crops have added about $100 billion to world crop output, avoided massive pesticide use and greenhouse gas emissions, spared vast tracts of land and fed millions of additional people worldwide, said Professor Calestous Juma of the Harvard Kennedy School's Belfer Center for Science and International Affairs.

Clinicians often wait for 'red flags' before discussing elderly driving

AURORA, Colo. (June 3, 2013) – Clinicians often wait too long before talking to elderly patients about giving up driving even though many may be open to those discussions earlier, according to a new study from the University of Colorado School of Medicine and the CU College of Nursing.

Evidence mounts that 4 lifestyle changes will protect heart, reduce your risk of death

A large, multi-center study led by Johns Hopkins researchers has found a significant link between lifestyle factors and heart health, adding even more evidence in support of regular exercise, eating a Mediterranean-style diet, keeping a normal weight and, most importantly, not smoking.

Genome hints at markers for higher-producing, better-tasting chocolate

The freshly sequenced genome of the most commonly cultivated cacao plant in the world is revealed in the open access journal Genome Biology this week. Researchers have utilised high quality DNA sequences to demonstrate the usefulness and quality of the sequence to identify genetic markers that can lead to higher yielding cocoa plants that still produce better tasting cocoa.

New method of mass-producing high-quality DNA molecules

A new method of manufacturing short, single-stranded DNA molecules can solve many of the problems associated with current production methods. The new method, which is described in the scientific periodical Nature Methods, can be of value to both DNA nanotechnology and the development of drugs consisting of DNA fragments.
