Scientists discover a direct link from the brain’s emotion circuit to the movement circuit

During high stress situations such as making a goal in soccer, some athletes experience a rapid decline in performance under pressure, known as “choking.” Now, Salk Institute researchers have uncovered what might be behind the phenomenon: one-way signals from the brain’s emotion circuit to the movement circuit. The study, which Continue Reading

Scientists identify gene as master regulator in schizophrenia

Using computational tools to investigate gene transcription networks in large collections of brain tissues, a scientific team has identified a gene that acts as a master regulator of schizophrenia during early human brain development. The findings may lay the groundwork for future treatments for the highly complex neuropsychiatric disorder. “Because Continue Reading

Scientists identify bombali ebolavirus in bats in Guinea

The sixth ebolavirus, Bombali virus, has been detected in insect-eating bats in Guinea. In addition to findings reported by researchers earlier this month, scientists from the University of California, Davis, detected the virus in Angolan free-tailed bats roosting inside people’s houses in Guéckedou and Kissidougou. UC Davis One Health Institute Continue Reading

Scientists establish link between prenatal HIV exposure and decreased infant immunity

In the August 16 edition of Nature Scientific Reports, scientists at the University of Rhode Island provide concrete evidence linking the specific immune responses in HIV-negative babies to the HIV-positive status of their mothers. The work was carried out in the laboratory of Barbara Lohman-Payne, associate research professor with URI’s Continue Reading

Scientists discover hidden differences among cells that may help them evade drug therapy

University of Maryland researchers have discovered that seemingly identical cells can use different protein molecules to carry out the same function in an important cellular process. The scientists named this newly discovered variability “functional mosaicism,” and it has significant implications for the development of therapeutic treatments, which are often designed Continue Reading

Scientists isolate protective proteins that influence outcomes for type 2 diabetes

Scientists from the School of Medicine, Trinity College Dublin, have, for the first time, discovered a family of proteins that are associated with lower blood sugar levels among obese patients with type 2 diabetes. Their research is published today in the international journal Nature Communications. The study showed that patients Continue Reading

Heart regeneration: Scientists uncloak one of nature’s deepest secrets

The long-sought Holy Grail for heart attack patients has been a method to regenerate healthy new tissue, but the basic building blocks required to remodel an injured heart have remained elusive—until now. Scientists at the University of Texas Southwestern have uncloaked the molecular mechanisms underlying heart regeneration in the only Continue Reading

Scientists link ‘hunger hormone’ to memory in Alzheimer’s study

Scientists at The University of Texas at Dallas have found evidence suggesting that resistance to the “hunger hormone” ghrelin in the brain is linked to the cognitive impairments and memory loss associated with Alzheimer’s disease (AD). The findings, based on observations of postmortem brain-tissue samples from Alzheimer’s patients and on Continue Reading

Scientists find how to block inflammatory molecules in mouse model of multiple sclerosis

Your immune system comes ready for battle against bacteria, viruses, fungi and even cancer. But in cases of autoimmune disease, the immune system’s superpowers turn it into a supervillain. Now, Salk Institute scientists have discovered a way to stop certain immune system cells from mistakenly attacking the body. Their findings, Continue Reading
