CORVALLIS, Ore. – The number of Americans wanting their government to stay out of international affairs is higher than it has been since the Vietnam War, according to a new analysis.

UPTON, NY-Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have identified two promising candidates for the development of drugs against human adenovirus, a cause of ailments ranging from colds to gastrointestinal disorders to pink eye. A paper published in FEBS Letters, a journal of the Federation of European Biochemical Societies, describes how the researchers sifted through thousands of compounds to determine which might block the effects of a key viral enzyme they had previously studied in atomic-level detail.
New research reveals that when red blood cells are hit with laser light, they produce high frequency sound waves that contain a great deal of information. Similar to the way one can hear the voices of different people and identify who they are, investigators reporting in the July 2 issue of Biophysical Journal, published by Cell Press, could analyze the sound waves produced by red blood cells and recognize their shape and size. The information may aid in the development of simple tests for blood-related diseases.
An important minority — 13.5% — of Canadian Forces personnel who served in support of the Afghanistan mission in 2001–08 have been found to have a mental health disorder related to their deployment, according to a study published in CMAJ (Canadian Medical Association Journal).
COLLEGE PARK, MD - A tiny protein called ubiquitin – so named because it is present in every cell of living things as dissimilar as hollyhocks and humans - may hold the key to treatment for a variety of diseases from Parkinson's to diabetes. The protein, found in all eukaryotes (organisms with membranous cells), was considered unimportant when it was described in 1975.
The white toothed shrew genus Crocidura is known as the largest mammal genus, with more than 180 species distributed around the world. A recent genetic analysis of the white toothed shrew fauna of Vietnam revealed the misinterpretations of previous morphological studies of the species, including the description of a new species of these very small mammals. The study was published in the open access journal ZooKeys.
Cancer cells have alteration in metabolic pathways as a result of oncogenes that promote tumor growth. NRF2 (nuclear factor erythroid-derived 2-related factor 2) works as a "master gene" that turns on stress response by increasing numerous antioxidants and pollutant-detoxifying genes to protect the lungs from variety of air pollutants such as diesel exhaust and cigarette smoke. However, researchers at the Johns Hopkins Bloomberg School of Public Health and others have found for the first time that NRF2 signaling also plays a role in the growth of tumor cells by altering metabolic pathways.
The logistics were impressive, the timeframe tight, the conditions tough.
From 26 May to 7 June 2013, nearly 150 experts from 40 countries set up shop on a military training ground near Veszprém, Hungary, for a simulated search for evidence of a nuclear explosion. Fifteen trucks transported 120 tons of state-of-the-art equipment from the CTBTO's Vienna storage facility to the site, where a fully functioning base of operations was established. Welcome to the world of on-site inspections (OSI).
Winning sounds on slot machines make gambling more exciting, according to a new study by Mike Dixon and colleagues from the University of Waterloo in Canada. Moreover, their work shows that sounds also cause players to overestimate the number of times they won while playing on slot machines. The study is published online in Springer's Journal of Gambling Studies.
BOSTON – July 1, 2013 -- Joslin scientists report that salsalate, a drug used to treat arthritis, lowers blood glucose and improves glycemic control in type 2 diabetes. These findings, which were published today by the Annals of Internal Medicine, provide additional evidence that salsalate may be an effective drug to treat type 2 diabetes.
Scientists at A*STAR's Genome Institute of Singapore (GIS) and the Max Planck Institute for Molecular Genetics (MPIMG) in Berlin (Germany) have discovered a molecular network in human embryonic stem cells (hESCs) that integrates cell communication signals to keep the cell in its stem cell state. These findings were reported in the June 2013 issue of Molecular Cell.
To convert a gene into a protein, a cell first crafts a blueprint out of RNA. One of the main players in this process has been identified by researchers led by Dr. Jessica Jacobs at the Ruhr-Universität Bochum. The team "fished" a large complex of proteins and RNA, which is involved in the so-called splicing, from the chloroplasts of the green alga Chlamydomonas reinhardtii. This cuts non-coding regions out of the messenger RNA, which contains the protein blueprint.
As the outermost layer of skin, epidermis is crucial in forming a permeability barrier and protection against various environmental agents. Thus, investigating the biology of its most important cell type, the keratinocyte, is key to understanding the effects of solar ultraviolet radiation in skin, and helps design effective means of protection against excessive exposure. It has already previously been shown with both cell culture and in vivo animal models that UV irradiation increases the expression of hyaluronan, which is an important carbohydrate of the extracellular matrix.
A study by researchers at Hospital for Special Surgery has provided the first evidence that the shape of a person's knee could be a factor in the decision of whether a patient should undergo anterior cruciate ligament (ACL) reconstruction after an ACL tear. The study is published online ahead of print in the Proceedings of the Institution of Mechanical Engineering.
Abiraterone acetate (abiraterone for short, trade name: Zytiga) has been approved in Germany since December 2012 for men with metastatic prostate cancer that is not responsive to hormone blockade, who only have mild symptoms or so far none at all, and in whom chemotherapy is not yet indicated. In an early benefit assessment pursuant to the "Act on the Reform of the Market for Medicinal Products" (AMNOG), the German Institute for Quality and Efficiency in Health Care (IQWiG) examined whether abiraterone offers an added benefit compared with the present standard therapy.
