Material scientists have created a system, using nano-sized molecules of gold, that induces and projects electrical current across molecules, similar to that of photovoltaic solar cells.

A novel — and rapid — anti-cancer drug development strategy has resulted in a new drug that stops kidney and pancreatic tumors from growing in mice. Researchers have found a drug that binds to a molecular “switch” found in cancer cells and cancer-associated blood vessels to keep it in the “off” position.

New insights on what causes Alzheimer’s disease could arise from a recent discovery made by bioengineers. The finding concerns the infamous amyloid beta peptides (A²) — fragments of which form plaques thought to play a role in Alzheimer’s disease. The bioengineers found that amyloid beta peptides spontaneously trigger calcium waves in purified cultures of astrocyte [...]

Several distinct mutations found in a subset of patients with acute myelogenous leukemia result in excess production of the same metabolite, according to new research.
Students can learn some science concepts just as well from computers simulations as they do from direct observation, new research suggests. A study found that people who used computer simulations to learn about moon phases understood the concepts just as well — and in some cases better — than did those who learned from collecting [...]
Brain networks that allow individuals to put social decisions on the back burner are impacted by genetics, a new study indicates. This capability has been shown to be abnormal in a number of psychiatric disorders.

Elephants can move fast, but can they ever be said to be truly “running”? Researchers have measured the colossal forces generated by high-speed elephants and found that the animals do conserve energy like runners by recycling it like a pogo stick, however, they do not bounce like runners. What is more they are three times [...]

A chemical compound found normally in the blood shows promise in treating and preventing an intractable form of heart failure in a mouse model of the disease.

Near the center of a Martian crater about the size of Connecticut, hundreds of exposed rock layers form a mound as tall as the Rockies and reveal a record of major environmental changes on Mars billions of years ago.

First blinded study of venous insufficiency prevalence in multiple sclerosis shows promising results
More than 55 percent of multiple sclerosis patients participating in the initial phase of the first randomized clinical study to determine if persons with MS exhibit narrowing of the extracranial veins, causing restriction of normal outflow of blood from the brain, were found to have the abnormality.
