Scientists have linked a new protein to Alzheimer's disease, different from the amyloid and tau that make up the sticky brain plaques and tangles long known to be its hallmarks.
New research has identified, for the first time, the structural damage at a molecular level that excessive alcohol abuse causes to the brain. The study detected the loss and modification of several key cellular proteins in the brains of alcoholics.
Research in seven- and 11-month-old infants shows that speech sounds stimulate areas of the brain that coordinate and plan motor movements for speech. The study suggests that baby brains start laying down the groundwork of how to form words long before they actually begin to speak.
Two years ago, the exceptional creativity of Parkinson's patients was demonstrated in a review for Behavioral Neuroscience. Now, a new empirical study definitively demonstrates that Parkinson's patients are more creative than their healthy peers.
A team of researchers at the Neuroscience Institute at Georgia State University has discovered that hidden differences in the properties of neural circuits can account for whether animals are behaviorally susceptible to brain injury. These results could have implications for the treatment of brain trauma.
In recent years, aggressive research and substantial financial investments have been directed at discovering pre-symptomatic indicators of cancer, known as biomarkers. But as lead author researchers at Arizona State University’s Biodesign Institute emphasize in a new study, the quest for cancer biomarkers has been stymied by a number of factors. They describe a new technique for early disease detection, which they call immunosignaturing.
Scientists at the University of East Anglia have shown how the main psychoactive ingredient in cannabis could reduce tumor growth in cancer patients. Research reveals the existence of previously unknown signaling platforms which are responsible for the drug’s success in shrinking tumors. It is hoped that the findings could help develop a synthetic equivalent with anti-cancer properties.
A third of Alzheimer’s disease cases worldwide can be attributed to risk factors that can be potentially modified, such as lack of education and physical inactivity, according to new research.
Being sick due to an infection can make us feel lousy. But what must the ecosystem of bacteria, or microbiota, colonizing our guts be going through when hit with infection? A new study has utilized unique computational models to show how infection can affect bacteria that naturally live in our intestines.
Reducing the amount of alcoholic beverages consumed, even for light-to-moderate drinkers, may improve cardiovascular health, including a reduced risk of coronary heart disease, lower body mass index (BMI), and blood pressure, according to a new multi-center study.
Bacterial Respiratory Tract Colonization Prior to Catching the Flu May Protect Against Severe IllnessJuly 11, 2014 1:10 pm | News | Comments
Many studies have shown that more severe illness and even death are likely to result if you develop a secondary respiratory infection after developing influenza. Now, however, a team of researchers based at The Wistar Institute has determined that if you reverse the order of infection, the bacteria Streptococcus pneumoniae (often called pneumococcus) may actually protect against a bad case of the flu.
Health researchers from the University of Copenhagen have uncovered new knowledge about the immune system in a mouse study, which indicates that natural birth improves the immune system of the pups. A number of studies suggest that children delivered by Caesarean section have a different intestinal flora than children delivered by natural birth. But it is still unknown why this is the case and what it means for the immune system.
Researchers have moved one step closer to a gene therapy that could silence the faulty SOD1 gene responsible for triggering a form of motor neuron disease also known as amyotrophic lateral sclerosis (ALS).
In a new study, scientists have shed new light on these complex processes, showing that a particular protein plays a far more sophisticated role in neuron development than previously thought.
A Mississippi girl born with the AIDS virus and in remission for years despite stopping treatment now shows signs that she still harbors HIV — and therefore is not cured.
Scientists have discovered that measles and Nipah viruses manipulate the phosphorylation state of the immune sensor MDA5, keeping it inactive while the virus enters cells and replicates.
Bowel cancer patients with high levels of vitamin D in their blood are more likely to survive the disease, a new study shows. Patients with the highest levels of vitamin D have half the risk of dying compared with those with the lowest levels, the findings reveal.
In an era of increasing concern about the prevalence of antibiotic-resistant illness, researchers have identified a promising new pathway to disabling disease: blocking bacteria’s access to iron in the body.
Although feelings are personal and subjective, the human brain turns them into a standard code that objectively represents emotions across different senses, situations and even people, reports a new study by Cornell University neuroscientist Adam Anderson.
Researchers have identified novel mutations in a well-known cancer-causing pathway in lung adenocarcinoma, the most common subtype of lung cancer. Knowledge of these genomic changes may expand the number of possible therapeutic targets for this disease and potentially identify a greater number of patients with treatable mutations because many potent cancer drugs that target these mutations already exist.
As climate change shifts the geographic ranges in which animals can be found, concern mounts over the effect it has on their parasites. Does an increased range for a host mean new territory for its parasites as well? Not necessarily, says a team of UC Santa Barbara scientists.
Researchers from North Carolina State University and the University of Minnesota have found for the first time that genetically identical strains of bacteria can respond very differently to the presence of sugars and other organic molecules in the environment, with some individual bacteria devouring the sugars and others ignoring it.
The protein that is mutated in Huntington’s disease is critical for wiring the brain in early life, according to a new Duke University study. The new findings add to growing evidence that Huntington’s and other neurodegenerative disorders, such as Alzheimer’s disease, may take root during development.
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.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on the possible double-punch of tick bites and how to control and undo years of heart damage.
