High-Fat, High-Sugar Diets Causes Bacterial Changes Related to Loss of Cognitive Function

Changes in bacteria making up the gut microbiome caused by high-fat and high-sugar diets appear related to a loss of cognitive function according to a study at Oregon State University. A study at Oregon State University indicates that both a high-fat and a high-sugar diet, compared to a normal diet, cause changes in gut bacteria […]

Researchers Show Mechanical Forces Role in Cell Function

New research from Yale University reveals how mechanical forces play an integral part in cell function. Nuclear membranes protect genes — life’s most precious cargo — but little is known about why they function in different tissue types. For instance, nuclei in brain cells tend to be soft and pliable while those in bone cells […]

Pupil Diameter Predicts Task Performance

Researchers from the Yale School of Medicine reveal how changes in the activity of individual neurons during performance of a task correspond exactly to the diameter of the pupil, showing signatures of high arousal for a wide diameter and low arousal for a small diameter. If you want to know who is ready to perform […]

Climate Change Will Affect the Functions Performed by Birds

New research from Yale University projects how climate change will affect the functions performed by birds in ecosystems worldwide. As changing climate reshapes the geographic range of thousands of bird species in the coming decades, ecosystems across wide swaths of the planet may be compromised, a new study warns. Based on environmental projections for the […]

New Species of Horned Dinosaur

A newly published study details the discovery of a new species of horned dinosaur, Regaliceratops peterhewsi. About 10 years ago, Peter Hews stumbled across some bones sticking out of a cliff along the Oldman River in southeastern Alberta, Canada. Now, scientists describe in the Cell Press journal Current Biology that those bones belonged to a […]

Brain Development During Adolescence in Bipolar Disorder

A newly published study from Yale University shows that key areas of the brain that help regulate emotions develop differently in adolescents with bipolar disorder. In brain areas that regulate emotions, adolescents with bipolar disorder lose larger-than-anticipated volumes of gray matter, or neurons, and show no increase in white matter connections, which is a hallmark […]

Scientists Identify Brain Circuit that Controls Emotional Decisions

A newly published study details how neuroscientists from MIT identified a neural circuit that controls decision-making under conflict. Some decisions arouse far more anxiety than others. Among the most anxiety-provoking are those that involve options with both positive and negative elements, such choosing to take a higher-paying job in a city far from family and […]

Researchers Discover Human-Specific Gene That Turns Back Cellular Clock

Yale researchers have discovered a gene that turns back the cellular clock, greatly aiding the reprogramming of mature cells. An exhaustive analysis of factors that allow mature cells to become like embryonic stem cells again has revealed a spliced form of a gene found only in primates that greatly aids the reprogramming of mature cells.

Researchers Generate a Family Tree for Living and Extinct Snakes

A team of researchers from Yale University analyzed snake genomes, modern snake anatomy, and information from the fossil record, generating a family tree for living and extinct snakes and illuminating major evolutionary patterns that have played out across snake evolutionary history. The ancestral snakes in the grass actually lived in the forest, according to the […]

New Study Shows How the Brain Responds to Food Cues

A new study set to appear in The Journal Neuroscience illustrates that it is the way the brain responds to food cues when individuals are not hungry that predicts weight gain and that the reasons why people gain weight can be fundamentally different. The way the brain responds while sipping a delicious milkshake can predict […]

New Research Reveals Opah as the First Warm-Blooded Fish

A newly published study reveals details about the opah – the first fully warm-blooded fish that circulates heated blood throughout its body. New research by NOAA Fisheries has revealed the opah, or moonfish, as the first fully warm-blooded fish that circulates heated blood throughout its body much like mammals and birds, giving it a competitive […]

Two Experimental Drugs Show Promise Against Drug-Resistant EGFR

Researchers from Yale University have discovered a key structural difference in the drug-resistant form of EGFR that could lead to new strategies to combat the disease. Drugs introduced more than a decade ago that target mutations in a protein known as the epidermal growth factor receptor (EGFR) held the promise of personalized treatments for a […]

Gene Expression Evolves Under a House-of-Cards Model

Using sophisticated modeling of genomic data from diverse species, scientists from Yale University have answered a longstanding question about which competing model of evolution works best. Their research suggests that the “house of cards” model — which holds that mutations with large effects effectively reshuffle the genomic deck — explains evolutionary processes better than the […]

Study Shows Extended Space Travel May Warp Astronauts' Brains

A new study from UC Irvine shows that galactic cosmic rays can cause dementia-like symptoms, making extended space trips to locations such as Mars more difficult to accomplish. What happens to an astronaut’s brain during a mission to Mars? Nothing good. It’s besieged by destructive particles that can forever impair cognition, according to a UC […]
