A neuroscience study provides new insight into the primal brain circuits involved in collision avoidance, and perhaps a more general model of how neurons can participate in networks to process information and act on it. In the study, neuroscientists tracked the cell-by-cell progress of neural signals from the eyes through the brains of tadpoles as they saw and reacted to stimuli including an apparently approaching black circle.
An important development in understanding how the bacterium that causes pneumonia, meningitis and septicaemia remains harmlessly in the nose and throat has been discovered at the University of Liverpool’s Institute of Infection and Global Health.
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.
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.
Around half of the genes that influence how well a child can read also play a role in their mathematics ability, according to scientists who led a study into the genetic basis of cognitive traits.
A breakthrough discovery into how living cells process and respond to chemical information could help advance the development of treatments for a large number of cancers and other cellular disorders that have been resistant to therapy. An international collaboration of researchers unlocked the secret behind the activation of the Ras family of proteins.
Insights into how cells move through the body could lead to innovative techniques to stop cancer cells from spreading and causing secondary tumors, according to new UCL research. Scientists discovered that cells can change into an invasive, liquid-like state to readily navigate the narrow channels in our body.
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.
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.
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.
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 National Institutes of Health has turned to neuroscientists at the nation’s most “Stone Cold Sober” university for help finding ways to treat drug and alcohol addiction. Brigham Young University professor Scott Steffensen and his collaborators have published three new scientific papers that detail the brain mechanisms involved with addictive substances.
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.
At 21, MS had Jennifer Molson “wheelchair bound.” But since her stem cell transplant, she has worked, driven, danced at her own wedding. The story had a room of 1,000 professional stem cell scientists sniffling loudly at the International Society for Stem Cell Research (ISSCR) meeting—said sniffling reaching a crescendo when the quiet, pretty Molson concluded: “I’m living proof stem cells can save lives.”
Almost 40 percent of pancreatic cancers– one of the deadliest forms of cancer– could be avoided in the UK through maintaining a healthy weight and not smoking, according to new research.
A discovery by Australian immunologists uncovered an additional role for antibody-making ‘B cells.’ The finding shows that B cells also participate in the development of ‘regulatory T cells.’ Until now, the only non-thymic cells known to educate the regulators were dendritic cells, which travel to the thymus to deliver ‘antigen’, samples of substances toxic to the body. We now know that B cells can do the same thing.
The risk of developing cancer increases with age. Factors like smoking and regular aspirin use also affect the risk of cancer—although in the opposite sense. Researchers from the University of Basel were now able to show that aspirin use and smoking both influence aging processes of the female genome that are connected to colorectal cancer.
Building on previous studies targeting the amygdala, a team of researchers have found that some brain cells recognize emotions based on the viewer's preconceptions rather than the true emotion being expressed.
Engineers and neuroscientists have developed a method to measure the response of an individual neuron to transcranial magnetic stimulation (TMS) of the brain. The advance will help researchers understand the underlying physiological effects of TMS.
