Scientists at UMass Medical School have performed the first CRISPR/Cas9 screen to discover human proteins that Zika virus needs for replication. This work, led by Abraham Brass, MD, PhD, assistant professor in microbiology & physiological systems, reveals new leads that may be useful for halting Zika, dengue and other emerging viral infections. “These genetic screens give us our first look at…
A new study led by Vanderbilt University scientist Dr. Suzana Herculano-Houzel has found that birds have significantly more neurons packed into their brains than are stuffed into mammalian and even primate brains of the same mass. The study, published online this week in the Proceedings of the National Academy of Sciences, provides a straightforward answer to a puzzle that researchers…
People with cancer are often told by their doctors approximately how long they have to live, and how well they will respond to treatments, but what if there were a way to improve the accuracy of doctors’ predictions? A new method developed by UCLA scientists could eventually lead to a way to do just that, using data about patients’ genetic…
A recent study suggests that who we are might be more integrated with where we are than previously thought. “The built environment can restrict or promote spatial cognition, which can influence one’s self-hood,” the researchers explain. “Our spatial coordinates and our ‘selves’ are intertwined.” The fact that experience can shape individual differences, which in turn can affect the quality of…
New research from an international team of evolutionary biologists, led by the University of Oxford, has used bacteria to show that acquiring duplicate copies of genes can provide a ‘template’ allowing organisms to develop new attributes from redundant copies of existing genes. The researchers allowed 380 populations of Pseudomonas aeruginosa bacteria to evolve novel metabolic traits such as the ability…
People who empathize easily with others do not necessarily understand them well. To the contrary: Excessive empathy can even impair understanding as a new study conducted by psychologists from Würzburg and Leipzig has established. “Successful social interaction is based on our ability to feel with others and to understand their thoughts and intentions,” Anne Böckler explains. She says that it…
