MRI scans reveal how brain protects memories

Two distinct parts of the human brain – the neocortex and the hippocampus (a part of the brain involved in higher-order brain functions) – have been shown to help protect our memories from interfering with one another. Researchers from the Wellcome Centre for Integrative Neuroimaging at the University of Oxford […]

Bacteria promote lung tumor development, study suggests

MIT cancer biologists have discovered a new mechanism that lung tumors exploit to promote their own survival: These tumors alter bacterial populations within the lung, provoking the immune system to create an inflammatory environment that in turn helps the tumor cells to thrive. In mice that were genetically programmed to […]

Opposite Effect: Protein Widely Known to Fight Tumors Also Boosts Cancer Growth

Search for a description of “p53” and it becomes clear that this human protein is widely known for its cancer-fighting benefits, leading to its renown as “the guardian of the genome.” Scientists at the University of California San Diego have published a new study challenging that description. Studying the “wild type” version […]

Policy must guide human embryo research, experts say

Human embryo research is a controversial topic that often pits the necessity of biomedical investigation against the moral commitment to protect early human life. A new series of research papers from Rice University’s Baker Institute for Public Policy is discussing human embryos and the related ethical, policy and scientific issues […]

Discovery could help improve cystic fibrosis treatment

Researchers exploring the effects of a long-standing treatment for cystic fibrosis have discovered a potential new target for drugs to treat the disease, which has no cure and typically cuts decades off the lives of patients. The research, a collaboration between the University of Saskatchewan in Canada and UC Berkeley, […]

FSU team breaks new ground in study of malignant pediatric brain tumor

Scientists are making important progress in the battle against a class of devilishly complex human pediatric brain cancers thanks to a new study from a team of Florida State University students and faculty. Among young children, there’s no brain tumor more common than medulloblastoma. But no specific and effective therapy […]

How the Body Fights Cancer and Intruders

The human body's immune system is like a vast team of special agents. Certain cells called T cells each individually specialize in recognizing a particular intruder, such as the influenza virus or salmonella. Determining a given T cell's target is a critical step in designing personalized treatments for cancers and […]

Study finds ways to help kids manage side effects of treatment for food allergies

For children undergoing immunotherapy – a promising treatment for peanut allergies – uncomfortable side effects can induce anxiety, perhaps to the point of skipping doses or dropping treatment entirely. But guiding young patients to the mindset that uncomfortable side effects are a sign that treatment is working can help reduce […]

New target for gastric cancer therapies

The team, at the University’s European Cancer Stem Cell Research Institute, found they could stop gastric cells dividing and growing by deleting a particular cell-surface receptor implicated in the function of stem cells. Dr Toby Phesse, Cardiff University, said: “The prognosis of gastric cancer is very poor, with very few […]

Sporadic Alzheimer’s in a Dish

Harvard Medical School geneticists have created a new model-in-a-dish of sporadic Alzheimer’s disease, which accounts for more than 90 percent of Alzheimer’s cases and tends to strike people without a family history of the disease. The model marks the first time researchers have identified the same molecular abnormalities across multiple […]

Bad Brakes of the Heart

Hypertrophic cardiomyopathy (HCM) is the most common genetic disease of the heart and a leading cause of sudden cardiac death in young people and athletes.Scientists have long known that the condition’s cardinal feature—an unusually thick heart muscle that contracts and relaxes abnormally—is fueled by some glitch in the heart’s molecular machinery. Yet, the spark-plug that […]

New precision medicine procedure fights cancer, advances treatment for pets and humans

In a first-of-its-kind study, scientists at the University of Missouri have helped advance a patient-specific, precision medicine treatment for bone cancer in dogs. By creating a vaccine from a dog’s own tumor, scientists worked with ELIAS Animal Health to target specific cancer cells and avoid the toxic side effects of chemotherapy, while […]

Cancer causes premature ageing

Leukaemia promotes premature ageing in healthy bone marrow cells – according to new research from the University of East Anglia. Findings published today in the journal Blood show that healthy bone marrow cells were prematurely aged by cancer cells around them. It is well known that ageing promotes cancer development. […]

Treating Cervical Cancer: What You Need to Know

Cervical cancer was once one of the most common cancers affecting U.S. women and now ranks 14th. The rate has declined sharply with the introduction of the Pap test, a screening procedure that can find changes in the cervix before the cancer develops. The test can also help to find cervical cancer at an […]

Study suggests how high blood pressure might contribute to Alzheimer’s

The brain’s system for removing waste is driven primarily by the pulsations of adjoining arteries, University of Rochester neuroscientists and mechanical engineers report in a new study. They also show that changes in the pulsations caused by high blood pressure slow the removal of waste, reducing its efficiency. This might […]
