A first step to tomorrow’s hearing aid

This is the first step towards developing a brain-controlled hearing aid. A hearing aid basically enhances all the sounds in our surroundings. This means, for example, that during a restaurant visit, background noise is increased just as much by a hearing aid as the speech from the person sitting opposite. […]

Dementia Risk Doubles Following Concussion

Dementia should join the expanding list of possible complications following concussion, even if the patient did not lose consciousness, say researchers from UCSF Weill Institute for Neurosciences and the San Francisco Veterans Affairs Health Care System. In their study, which tracked more than one-third of a million veterans, the likelihood of dementia was […]

No Embryo Required: Studying Development in the Lab

The big question As an embryo develops from a little glob of primitive cells, it patterns itself into precise, spatially organized regions and tissues. This requires that individual cells coordinate with one another over long distances by releasing and detecting specialized signaling molecules. How can cells, communicating only in this […]

First description of mEAK-7 gene could suggest path toward therapies for cancer, other diseases

For years, researchers have known that a gene called EAK-7 plays an important role in determining how long worms will live. But it remained unclear whether the gene had a counterpart in humans and – if it did – how that human version would work. Now, researchers led by UCLA’s […]

Scientists discover roadblocks that stop brain white matter healing

A new study identifies a molecule that may be critical to the repair of white matter, the fatty tissue wrapped around parts of brain cells that helps speed up communication. Damage to white matter is associated with several conditions, including multiple sclerosis and cerebral palsy, and can occur in the […]

Daily aspirin linked to double melanoma risk in men

Men who take once-daily aspirin have nearly double the risk of melanoma compared to men who are not exposed to daily aspirin, reports a new Northwestern Medicine study. Women, however, do not have an increased risk in this large patient population. “Given the widespread use of aspirin and the potential […]

Scientists grow artificial muscles to model muscular dystrophies

Personalized therapies are the future, but they do pose a challenge. If every therapy will be different, how do you test them? Obviously, doctors would have the best test subject available – the patient, but you can only do so much with him. Now a team if scientists lead by […]

MicroRNAs show signs of promise for prostate cancer screening tests

A team of medical researchers have taken a step in investigating whether a type of RNA found to be linked to cancers — called microRNAs — could one day be used as a more accurate screening test for prostate cancer. The researchers said that out of the 733 microRNAs analyzed […]

Mediterranean diet may protect against Alzheimer’s

A Western-style diet triggers changes in the brain that may predispose patients to Alzheimer’s disease decades before they show any sign of cognitive decline, according to new research by Weill Cornell Medicine investigators. In two studies, published in BMJ Open and in Neurology, the investigators showed that diet and insulin […]

X-ray laser opens new view on Alzheimer proteins

Graphene enables structural analysis of naturally occurring amyloids. A new experimental method permits the X-ray analysis of amyloids, a class of large, filamentous biomolecules which are an important hallmark of diseases such as Alzheimer’s and Parkinson’s. An international team of researchers headed by DESY scientists has used a powerful X-ray […]

Chemical Octopus Catches Sneaky Cancer Clues, Trace Glycoproteins

Cancer drops sparse chemical hints of its presence early on, but unfortunately, many of them are in a class of biochemicals that could not be detected thoroughly, until now. Researchers at the Georgia Institute of Technology have engineered a chemical trap that exhaustively catches what are called glycoproteins, including minuscule traces that have previously […]

Reprogrammed Stem Cell-Derived Neurons Survive Long-Term in Pigs with Spinal Cord Injuries

A major hurdle to using neural stem cells derived from genetically different donors to replace damaged or destroyed tissues, such as in a spinal cord injury, has been the persistent rejection of the introduced material (cells), necessitating the use of complex drugs and techniques to suppress the host’s immune response.

Less is more when it comes to developing bigger brains

A team from the University of Oxford and Cardiff University have used mathematical models to re-enact the complex process of brain development that occurs as initialising cells, otherwise known as progenitor cells, start to grow and begin to differentiate into more specialist cells at various points in time. By applying […]
