People with an autism spectrum disorder, or ASD, may experience sensory hypersensitivity more often than people without ASD, according to the National Autism Association. Among other responses, this hypersensitivity can lead to “sensory overload,” when sensory systems like vision or hearing are “overwhelmed” by stimuli. Scientists do not fully understand […]

Researchers have found a way to design an antibody that can identify the toxic particles that destroy healthy brain cells – a potential advance in the fight against Alzheimer’s disease. Their method is able to recognise these toxic particles, known as amyloid-beta oligomers, which are the hallmark of the disease, […]

5.8 million Americans live with Alzheimer’s dementia, including 10% of all seniors 65 and older. Scientists at Cornell have discovered links between “stalls,” or clogged blood vessels in the brain, and Alzheimer’s. Stalls can reduce overall blood flow in the brain by 30%. The ability to prevent or remove stalls may […]

Many proteins are useful as drugs for disorders such as diabetes, cancer, and arthritis.

Pairing a blood-thinning drug with aspirin daily for patients who have an angioplasty with a stent can contribute to better health outcomes, including lower risk of death, than aspirin alone, according to a recent study by cardiologists at the University of Alberta and Mazankowski Alberta Heart Institute. Led by Kevin […]

For most people who die of cancer, the spread of the initial tumor is to blame. “Metastasis is what kills most cancer patients,” says Serge Fuchs, a professor in Penn’s School of Veterinary Medicine. “Yet there are not many, if any, drugs that specifically target metastatic processes.” In a paper in […]

In recent wars, about 53,000 U.S. military veterans have suffered serious injuries, often involving large amounts of tissue loss. Many more Americans also suffer from long-term injuries resulting from car crashes, accidents, and surgeries. Many of these injuries are disfiguring and debilitating. Now, imagine if lost skeletal muscle could be […]

UC Riverside engineers are transforming yeast, both the domesticated kind used to make bread and beer and lesser-known wild species, so it can be used in a variety of new ways — including fighting cancer. Yanran Li, a UC Riverside assistant professor of chemical and environmental engineering, is working with […]

An adenovirus is now better able to target and kill cancer cells due to the addition of an RNA stabilizing element.
