In a great stride toward finding an effective treatment for early-stage neurodegenerative diseases, UC Santa Barbara neurobiologist Kenneth S. Kosik and collaborators have uncovered a “druggable” mechanism of pathological tau protein aggregation. For the millions of people at risk for frontotemporal dementia and a host of other such conditions including Alzheimer's, this […]

All parents want their children to be not only healthy but also better than them in many ways. Can genetic engineering help them achieve that? Scientific and Moral Aspects of Genetic Modification Gene manipulation has made colossal strides over the last decades. Scientists claim that genetic engineering of children has […]

Researchers at Karolinska Institutet have discovered the underlying cause of a hereditary muscle disease first characterised in a Swedish family in 1980. It proves to be the first identified disease caused by defective myoglobin, the protein that transports oxygen in muscle cells. The study is published in Nature Communications. Sarcoplasmic body […]

Pregnant women who use cannabis may slightly increase the risk their unborn child will develop psychosis later in life, suggests new research from Washington University in St. Louis. “Our research shows that prenatal marijuana exposure after maternal knowledge of pregnancy is associated with a small increase in psychosis proneness during […]

Scientists at the University of Virginia and elsewhere have mapped out how the body transports testosterone, and their surprising findings may explain low testosterone levels seen in men with diabetes or patients on certain medications. The discovery allows scientists to understand exactly how testosterone, the male sex hormone, binds to a […]

An adhesive gel packed with light-activated chemicals can seal cuts or ulcers on the cornea, the clear surface of the eye, and then encourage the regeneration of corneal tissue, according to a preclinical study by Harvard Medical School researchers at Massachusetts Eye and Ear published online in Science Advances. The new […]

A new UW Carbone Cancer Center study, published online in EBioMedicine, has developed a model that mimics the tumor’s blood supply on a three-dimensional  platform designed in the laboratory of Dr. David Beebe, professor of biomedical engineering and pathology. The authors of the study, led by Drs. Jose “Tony” Jimenez-Torres and Maria […]

In one of the longest follow-up studies of its kind, researchers found that their specially bioengineered blood vessels evolved into living tissue after human implantation. Researchers from Yale and the North Carolina-based company Humacyte published results in Science Translational Medicine on the progress of their bioengineered human vessels (HAVs). The results show […]

Brain stem cells in people with the most severe form of multiple sclerosis look much older than they really are, according to a study led by UConn Health and published in the Proceedings of the National Academy of Sciences (PNAS). The prematurely old cells act differently in the brain than normal ones, […]

A healthy adult makes about 2 million blood cells every second, and 99 percent of them are oxygen-carrying red blood cells. The other one percent are platelets and the various white blood cells of the immune system. How all the different kinds of mature blood cells are derived from the […]

A new study in mice suggests that consuming the chemical compounds found in thermally abused cooking oil may trigger genetic changes that promote the progression of late-stage breast cancer. Thermally abused frying oil – cooking oil that has been repeatedly reheated to high temperatures – may act as a toxicological […]

Your baby delights you but he’s causing you concern. Why is it so hard to get him to look at you? Why doesn’t he gesture as much as other babies you know? Your relatives say you worry too much. They blame your parenting for the child’s frequent tantrums. Still, you […]

The human brain is one of the most complex organs. Its complexity challenges our ability to study its structure and function. As a result, many brain-related diseases are not fully understood and adequate treatments are often lacking. Scientists from Max Planck Institute of Psychiatry were able to model a developmental […]

High BMI and mental ill-health go increasingly hand-in-hand to present a combined health risk for children from mid-childhood, according to a new study.
