Some manufacturers are turning away from using triclosan as an antimicrobial ingredient in soaps, toothpastes and other products over health concerns. Now, scientists are reporting new evidence that appears to support these worries.
Scientists have identified a protein complex, a novel role for a protein known as RGS7, that...
Measuring tumors’ oxygen levels could help doctors make decisions about treatments, but there’s...
The process of metastasis is still poorly understood. Now, a research team has developed a simple test that can reveal the evolutionary relationships among various tumor sites within a patient, information that may someday help with treatment planning.
Working with mice and rabbits, scientists have found a way to block abnormal cholesterol production, transport and breakdown, successfully preventing the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans.
Diagnosed with retinitis pigmentosa as a teenager, Roger Pontz has been almost completely blind for years. Now, thanks to a high-tech procedure that involved the surgical implantation of a "bionic eye," he's regained enough of his eyesight to catch small glimpses of his wife, grandson and cat.
A dream solution to cancer metastasis has been to develop a method that can track and kill the cancer cells that are on the move. The complexity at which those cancer cells operate has long been a formidable obstacle to stopping metastases, which cause 90 percent of cancer deaths, but that may change.
Older parents are more likely to have a child who develops an autism spectrum disorder (ASD) than are younger parents, according to a recent study.
Scientists have now shown how double stranded RNA, such as viral genetic information, is prevented from entering the nucleus of a cell. During the immune response against viral infection, the protein ADAR1 moves from the cell nucleus into the surrounding cytoplasm.
Imaging of the coronary arteries with computed tomography angiography provides an accurate assessment of arterial plaque and could have a dramatic impact on the management of diabetic patients who face a high risk of heart attacks and other cardiovascular events, according to a new study.
A team of researchers has developed a test that can rapidly assess several DNA repair systems, which could help determine individuals’ risk of developing cancer and help doctors predict how a given patient will respond to chemotherapy drugs.
Scientists collaborated on the first large-scale investigation into the evolution of self-control in animals, defined in the study as the ability to inhibit powerful but ultimately counter-productive behavior.
Using reprogrammed skin cells, researchers have for the first time used stem cell techniques to grow fully functional assemblies of the cells that line airways leading to the lungs.
Scientists have worked together to create tools for observing nerves in living animals that signal between themselves in real time, which will help them understand how those individual signals add up to the complex collection of a person's thoughts and memories.
Researchers say that rapid-eye-movement sleep behavior disorder (RBD), which causes people to act out their dreams, is the best current predictor of brain diseases like Parkinson's and Alzheimer's.
Muscle weakness from long-term alcoholism may stem from an inability of mitochondria, the powerhouses of cells, to self-repair, according to a new study. In the research, scientists found evidence that chronic heavy alcohol use affects a gene involved in mitochondrial repair and muscle regeneration.
The most effective way to tackle debilitating diseases is to punch them at the start and keep them from growing. Research shows that a small “molecular tweezer” keeps proteins from clumping, the first step of disorders such as Parkinson’s disease, Alzheimer’s disease and Huntington’s disease.
Most drugs used to treat lung, breast and pancreatic cancers also promote drug-resistance and ultimately spur tumor growth. Researchers have discovered a biomarker called CD61 that appears responsible for inducing tumor metastasis by enhancing the stem cell-like properties of cancer cells.
A single type of cell in the lining of the bladder is responsible for most cases of invasive bladder cancer, according to researchers. This study is the first to pinpoint the normal cell type that can give rise to invasive bladder cancers.
Neuroscientists have made a discovery that turns 160 years of neuroanatomy on its head. Myelin, the electrical insulating material in the body long known to be essential for the fast transmission of impulses along the axons of nerve cells, is not as ubiquitous as thought, according to new work.
Ginseng can help treat and prevent influenza and respiratory syncytial virus (RSV), a respiratory virus that infects the lungs and breathing passages, according to new research findings.
Although doctors have long known that people with Down syndrome have a heightened risk of developing acute lymphoblastic leukemia (ALL) during childhood, they haven’t been able to explain why. Now, a team investigators has uncovered a connection between the two conditions.
An international research team identified a new superbug that caused a bloodstream infection in a Brazilian patient. The new superbug is part of a class of highly-resistant bacteria known as methicillin-resistant Staphylococcus aureus (MRSA). The superbug has also acquired high levels of resistance to vancomycin, the most common and least expensive antibiotic used to treat severe MRSA infections worldwide.
Researchers have sequenced the entire genome and all the RNA products of the most important pathogenic lineage of Cryptococcus neoformans, a strain called H99.
The presence of chronic inflammation in benign prostate tissue was associated with high-grade, or aggressive, prostate cancer, and this association was found even in those with low prostate-specific antigen (PSA) levels, according to a new study.
Researchers have discovered an unexpected phenomenon in the organs that produce sperm in fruit flies: when a certain kind of stem cell is killed off experimentally, another group of non-stem cells can come out of retirement to replace them.
Size doesn’t matter as long as long as you can get the job done. That said, one may be forgiven the impression that larger molecules—antibodies and related constructs, or T cells themselves being used in immunotherapies—were preferentially presented at American Association of Cancer Research annual conference
Indiana University researchers have detected new early-warning signs of the potential loss of sight associated with diabetes. This discovery could have far-reaching implications for the diagnosis and treatment of diabetic retinopathy, potentially impacting the care of over 25 million Americans.
