Liquefied brain tissue after stroke may harm surviving brain, UA study finds

Scientists have known for years that the brain liquefies after a stroke. If cut off from blood and oxygen for a long enough period, a portion of the brain will die, slowly morphing from a hard, rubbery substance into liquid goop.

Local environment plays crucial role in aggressiveness of breast cancer

Breast cancer is the most commonly diagnosed cancer in women -- one in eight (12.4 percent) in the U.S. will be diagnosed with it. Invasive breast cancer is dangerous for two reasons: It can aggressively spread to other organs in the body, and it is likely to recur.

Researchers discover five new genetic changes that may increase pancreatic cancer risk

In what is believed to be the largest pancreatic cancer genome-wide association study to date, researchers at the Johns Hopkins Kimmel Cancer Center and the National Cancer Institute, and collaborators from over 80 other institutions worldwide discovered changes to five new regions in the human genome that may increase the risk of pancreatic cancer.

Scientists show that cutting-edge technique can efficiently sort nano-sized particles

A new cellular messenger discovered by Weill Cornell Medicine scientists may help reveal how cancer cells co-opt the body's intercellular delivery service to spread to new locations in the body.

Researchers create minuscule, light-powered wires to modify electrical signaling between neurons

The human brain largely remains a black box: How the network of fast-moving electrical signals turns into thought, movement and disease remains poorly understood. But it is electrical, so it can be hacked--the question is finding a precise, easy way to manipulate electrical signaling between neurons.

Study finds novel therapeutic strategy that preserves neuromuscular synapses in ALS mouse model

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, causes lethal respiratory paralysis within several years of diagnosis. There are no effective treatments to slow or halt this devastating disease.

Cancer initiation found to be similar across organs

Recent research at Washington University School of Medicine in St. Louis demonstrated that mature cells in the stomach sometimes revert back to behaving like rapidly dividing stem cells.

Some genes can drive both metastasis and initial stages of tumor growth

In spite of the difference between the cell functions responsible for giving rise to a tumor and for the metastasis of this same tumor, studies at IRB Barcelona using the fly Drosophila melanogaster reveal that some genes can drive both phenomena.

Cutting either carbs or fats shaves off excess weight in the same proportion, study reveals

New evidence from a study at the Stanford University School of Medicine might dismay those who have chosen sides in the low-fat versus low-carb diet debate.

Researchers discover new weakness in sleeping sickness parasites

Trypanosomes are single-celled parasites that cause diseases such as human African sleeping sickness and Nagana in animals. But they are also used in basic research as a model system to study fundamental biological questions.

Study reveals a significant link between heavy alcohol use and dementia

New research has found alcohol use disorders to be one of the most vital avoidable risk factors for the onset of all types of dementia, early-onset dementia in particular.

People with major depressive disorder have reduced arginine levels, study shows

People suffering from major depressive disorder, MDD, have reduced arginine levels, a new study from the University of Eastern Finland shows. Arginine is an amino acid which the body uses to produce, e.g., nitric oxide.

Australia lagging behind in psychedelic science renaissance

With research from the US showing that MDMA, or ecstasy, can effectively cure PTSD, it is time for Australia to embrace psychedelic science, according to Edith Cowan University addiction studies expert Dr Stephen Bright.

Bioactive compound limits collateral damage in the kidneys after heart attack

A heart attack triggers an acute inflammatory response at the damaged portion of the heart's left ventricle. If this acute inflammation lingers, it can lead to stretching of the ventricle and heart failure. The inflammation can claim another victim -- the kidneys.

Study reveals biological relevance of sex in effects of D-galactose induced aging

A research study by the Universitat Autònoma de Barcelona in collaboration with the University of La Laguna demonstrates in mice the biological relevance of sex in the effects of accelerated ageing caused by a chronic treatment of D-galactose, a sugar found abundantly in milk and to a lesser extent in fruits and vegetables.
