Bacterial infections usually announce themselves with pain and fever but often can be defeated with antibiotics—and then there are those that are sneaky and hard to beat. Now, scientists have built a new weapon against such pathogens in the form of tiny DNA pyramids. Their study found the nanopyramids can flag bacteria and kill more of them than medicine alone.
Adults with extreme obesity have increased risks of dying at a young age from cancer and many other causes including heart disease, stroke, diabetes, and kidney and liver diseases, according to results of a new analysis.
Neurological scientists have found that using cinnamon, a common food spice and flavoring material, can reverse the biomechanical, cellular and anatomical changes that occur in the brains of mice with Parkinson’s disease (PD).
A government scientist cleaning out an old storage room at a research center near Washington made a startling discovery last week- decades-old vials of smallpox packed away and forgotten in a cardboard box.
An AIDS research team at Iowa State University will not get the final $1.38 million payment of a National Institutes of Health five-year grant after a team member admitted last year to faking research results.
Scientists have identified a set of 10 proteins in the blood which can predict the onset of Alzheimer’s, marking a significant step towards developing a blood test for the disease.
Re-examination of a circa 100,000-year-old archaic early human skull found 35 years ago in Northern China has revealed the surprising presence of an inner-ear formation long thought to occur only in Neandertals.
Mice exposed to low doses of arsenic in drinking water, similar to what some people might consume, developed lung cancer, researchers have found. Arsenic is present in the environment as a naturally occurring substance or due to contamination from human activity.
Samples isolated from Chobani yogurt that was voluntarily recalled in September 2013 have been found to contain the most virulent form of a fungus called Mucor circinelloides, which is associated with infections in immune-compromised people.
A few therapies derived from human medicine are available for dogs, but a very successful form of therapy by which antibodies inhibit tumor growth has not yet been available for animals. Now, scientists have developed, for the first time, antibodies to treat cancer in dogs.
Researchers have begun to connect the dots between a schizophrenia-linked genetic variation and its effect on the developing brain. Their experiments show that the loss of a particular gene alters the skeletons of developing brain cells, which in turn disrupts the orderly layers those cells would normally form.
An association between high blood cholesterol and breast cancer has been found in a study of more than 1 million patients over a 14-year time period in the UK.
Researchers completed a study that generated pseudogene expression profiles in 2,808 patient samples representing seven cancer types. The results indicated that the science of pseudogene expression analysis may very well play a key role in explaining how cancer occurs.
Scientists have shown that a member of the protein family known as SUMO (small ubiquitin-like modifier) is a key to why tumor cells multiply uncontrollably, especially in the case of glioblastoma.
Located deep in the human gut, the small intestine is not easy to examine. Now, researchers are developing a new imaging technique involving nanoparticles suspended in liquid to form “nanojuice” that patients would drink.
Patients suffering from osteoporosis or bone fractures might benefit from a new discovery of the protein statherin, which plays an important role in bone regeneration.
A new study by radiation oncologists has found that proton beam therapy significantly improved disease free survival and tumor control when compared to IMRT in a variety of advanced head and neck cancers.
A team of researchers has shown for the first time that stem cells created using different methods produce differing cells. The findings provide new insights into the basic biology of stem cells and could ultimately lead to improved therapies.
Researchers at the University of California, San Diego School of Medicine say a protein essential to regulating cell cycle progression – the process of cell division and replication – activates a key tumor suppressor, rather than inactivating it as previously thought.
White-bread lovers take heart. Scientists are now reporting that this much-maligned food seems to encourage the growth of some of our most helpful inhabitants — beneficial gut bacteria. In addition to this surprising find, their study also revealed that when looking at effects of food on our “microbiomes,” considering the whole diet, not just individual ingredients, is critical.
Researchers have spotted a strong family trait in two distant relatives: The channels that permit entry of sodium and calcium ions into cells turn out to share similar means for regulating ion intake, they said.
A genomic analysis of clear cell renal cell carcinoma (ccRCC), the most common form of kidney cancer, from 72 patients has uncovered 31 genes that are key to development, growth and spread of the cancer, according to researchers.
Emotional and behavioral problems show up even with low exposure to lead, and as blood lead levels increase in children, so do the problems, according to new research.
The government is expanding its "mystery disease" program, funding a network at six universities around the country to help diagnose patients with diseases so rare they've been told they're undiagnosable. The National Institutes of Health has evaluated hundreds of these cold-case patients in its campus research hospital as part of a pilot program since 2008. Demand is so great, there's a waiting list.
Bone marrow transplants can reverse severe sickle cell disease in adults, a small study by government scientists found, echoing results seen with a similar technique used in children. The researchers and others say the findings show age need not be a barrier and that the technique may change practice for some adult patients when standard treatment fails.
