Wild potato germplasm that offers resistance to some major potato diseases has been identified by Agricultural Research Service (ARS) scientists.
Geneticists Dennis Halterman and Shelley Jansky pinpointed the resistant wild potato species in studies at the ARS Vegetable Crops Research Unit in Madison, Wis.
Exposure to chemical pollutants is of growing concern to regulators, health workers, and environmentalist groups alike. Now, researchers in the US and Russia have demonstrated that samples of human bone can act as a biological marker for dozens of metals and toxic elements across the periodic table. They describe details in a study published in the International Journal of Environment and Health.
College Park, MD (June 17, 2010) -- "Robust" is an adjective appreciatively applied to certain vintage wines, but when describing viruses and pathogens, robustness is a property that may be much less desirable. It evokes drug resistant microbes and other superbugs that can wreak havoc as researchers struggle to deal with new pandemics. How can we undercut this robustness?
Low-salt foods may be harder for some people to like than others, according to a study by a Penn State College of Agricultural Sciences food scientist. The research indicates that genetics influence some of the difference in the levels of salt we like to eat.
Those conclusions are important because recent, well-publicized efforts to reduce the salt content in food have left many people struggling to accept fare that simply does not taste as good to them as it does to others, pointed out John Hayes, assistant professor of food science, who was lead investigator on the study.
KNOXVILLE -- How do we begin to understand what early life was like on Earth about 700 million years ago as our planet shifted from an oxygen-free and probably ice-covered realm to the oxygen-rich world that we know today?
There is no evidence that the common practice of giving patients oxygen to inhale during a heart attack is beneficial, according to a new Cochrane Systematic Review. Until further research is carried out, the researchers say the possibility that giving oxygen may actually increase a patient's risk of dying cannot be ruled out.
Women who have had intrauterine devices (IUDs) fitted as contraceptives are less likely to become pregnant than those who have hormone injections, a new review by Cochrane Researchers has found. The review, which focused on women in developing countries, also found a possible link between contraceptive method and disease progression in HIV.
Being obese impacts on sexual health according to research published on bmj.com today.
Inbred male sperm have been found to fertilise fewer eggs when in competition with non-inbred males according to a new study by the University of East Anglia.
Research into the breeding habits of the red flour beetle, published today in Proceedings of the Royal Society B, shows that the reduced fitness of inbred beetles, known as 'inbreeding depression', reveals itself in competitive scenarios.
A study published this week in PLoS Medicine by Simon Hay and colleagues from the Malaria Atlas Project (MAP) concludes that there were an estimated 451 million clinical cases of Plasmodium falciparum malaria worldwide in 2007.
Identification of a key player in a signaling pathway involved in the development of melanoma – the deadliest form of skin cancer – may offer hope for new targeted melanoma therapies.
Despite a greater likelihood of poorer outcomes, many patients newly-diagnosed with early-stage lung cancer do not undergo surgery. New research indicates that among the factors associated with this decision include misunderstandings of the prognosis, negative perceptions of patient-physician communication and older age, with black patients more likely to not have surgery, according to a study in the June 16 issue of JAMA.
Patients with cystic fibrosis (CF) who have Methicillin-resistant Staphylococcus aureus (MRSA) detected in their respiratory tract have worse survival compared to CF patients without MRSA, according to a study in the June 16 issue of JAMA.
The most common cause of death in CF is respiratory failure secondary to pulmonary infection. The prevalence of MRSA in the respiratory tract of individuals with CF has increased substantially, and is now more than 20 percent, according to background information in the article. However, the effect of MRSA on outcomes in CF is unclear.
CHAPEL HILL – A new study led by UNC researchers that looks at newly diagnosed lung cancer patients and follows them from diagnosis forward is one of the first to give reasons why patients don't go to lung surgery and why surgery happens less often in blacks.
A study of twins shows that even with genes that put them at higher risk of cardiovascular disease, eating a Mediterranean-style diet can improve heart function, according to research reported in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal.
