Bone marrow transplants, which involve transplanting healthy blood stem cells, offer the best treatment for many types of cancers, blood disorders and immune diseases. Even though 22,000 of these procedures are performed each year in the US, much remains to be understood about how they work. A new USC and […]

About 31 million U.S. adults have food allergies, nearly half of which develop after age 18, according to a study published in JAMA Network Open. The research, a collaboration between Stanford food allergy expert Kari Nadeau, MD, PhD, and scientists at Northwestern University, is the first comprehensive examination of the prevalence of food allergies […]

A new study by Keck School of Medicine of USC researchers shows there's yet another reason to avoid high fat, high cholesterol diet: It can trigger changes in the immune system that lead to a serious form of non-alcoholic fatty liver diseases (NAFLD) known as non-alcoholic steatohepatitis (NASH). NAFLD is […]

Researchers from The University of Western Australia have conducted a study that has found young women who start having periods early and often have a high body mass index are more prone to cardiovascular problems later in life such as heart disease, stroke and diabetes. More than 800 young women […]

Undifferentiated uterine sarcoma is a very rare but extremely aggressive cancer type. It can be divided into four groups with different characteristics of clinical importance – a new study at Karolinska Institutet reveals.

Mice that sleep fitfully could help researchers unravel the mystery of insomnia. Researchers at Washington University School of Medicine in St. Louis studied mice genetically modified to mimic the genetic disease neurofibromatosis type 1 (NF1), which is associated with sleep problems. They found that the animals, like some people with […]

African-Americans may be twice as likely as Caucasian Americans to develop Alzheimer’s disease, but nobody knows why because studies investigating the underlying causes of illness have historically drawn from a nearly all-white pool of research participants. Consequently, little is known about how the neurodegenerative disease arises and progresses in people […]

Longevity is heritable, but that primarily applies to persons from families where multiple members are among the top 10 percent survivors of their birth cohort. The key to a long life can probably be found in the genes of these families. These are the conclusions of researchers at Leiden University […]

Blood levels of a special protein found only in the inner ear spike after exposure to loud noise, UConn Health researchers report. The findings point the way to blood tests that could warn people at risk of hearing loss before they suffer serious damage. Hearing loss can sneak up on […]

A research team from Imperial College London, led by Dr Ben Almquist, has developed a new molecule based on so-called traction force-activated payloads (TrAPs) which allow materials to talk to the body‘s natural repair systems and thereby activate healing processes. “Creatures from sea sponges to humans use cell movement to […]
