Optical illusions explained in a fly’s eyes

Why people perceive motion in some static images has mystified not only those who view these optical illusions but neuroscientists who have tried to explain the phenomenon. Now Yale neuroscientists have found some answers in the eyes of flies, they report Aug. 24 in the journal Proceedings of the National Academy of Sciences. It turns […]

Flexible targets help immune system make finely-tuned antibodies

An in-depth Garvan study of how the immune system generates effective antibodies provides new insights for vaccine design. Researchers at the Garvan Institute of Medical Research have uncovered a key strategy the immune system uses to generate effective antibodies, which could inform vaccine design for some of the most challenging viruses. In experimental models, the […]

Veterans undergoing elective PCI at community hospitals may have increased chance of death

Veterans who underwent elective percutaneous coronary intervention (PCI) for stable angina at a community facility were at a 33% increased hazard, or chance, of death compared to patients treated within the Veterans Affairs (VA) Healthcare System, according to an analysis of nearly 9,000 veterans published today in the Journal of the American College of Cardiology.

RNA quality control system goes awry in frontotemporal lobar degeneration

Researchers at Osaka University have identified a fault in the RNA quality control system of cells that leads to the haywire production of toxic proteins in frontotemporal lobar degeneration and amyotrophic lateral sclerosis (FTLD/ALS). Their new study, published in the EMBO Journal, shows that an abnormality of the C9orf72 gene produces toxic proteins that hinder […]

Reducing side effects during the treatment of brain tumours

Glioblastomas are among the most aggressive brain tumors in adults and difficult to treat due to their rapid growth and their diversity. Usually, the malignant tumors cannot be completely or permanently removed by surgery. Thus, a combined radio- and chemotherapy follows, which, however, can be associated with side effects on the entire human body. So-called […]

Overcoming therapeutic resistance in lung cancer

A protein highly expressed in lung cancer cells drives resistance to targeted therapies, report researchers at the Medical University of South Carolina in the Journal of Thoracic and Cardiovascular Surgery. In preclinical experiments, the researchers showed that inhibiting the protein caused the death of non-small cell lung cancer cells that had become resistant to therapy. […]

Excessive fructose consumption may cause a leaky gut, leading to fatty liver disease

Excessive consumption of fructose—a sweetener ubiquitous in the American diet—can result in non-alcoholic fatty liver disease (NAFLD), which is comparably abundant in the United States. But contrary to previous understanding, researchers at University of California San Diego School of Medicine report that fructose only adversely affects the liver after it reaches the intestines, where the […]
