Pigs help scientists understand human brain

For the first time, researchers in the University of Georgia’s Regenerative Bioscience Center have used an imaging method normally reserved for humans to analyze brain activity in live agricultural swine models, and they have discovered that pig brains are even better platforms than previously thought for the study of human neurological conditions such as Alzheimer’s and Parkinson’s. One immediate potential […]

Keeping kids’ minds active may cut obesity risks, scientists suggest

Should brain training be part of a healthy diet? Children’s minds use half their energy – and more mental activity might cut obesity risks, scientists say At five, children’s brain’s use up almost half the energy they get from their diets The glucose from food that we don’t use gets converted into fat  Scientists at Northwestern University and New York […]

Scientists identify a novel neural circuit mediating visually evoked innate defensive responses

Fear overgeneralization, a condition that limits the ability to discriminate between safety and threat, is an important pathological characteristic of anxiety-related syndromes such as post-traumatic stress disorder (PTSD), generalized anxiety disorder (GAD) and panic disorder. However, unlike traditional conditioned fear, the mechanism of processing innate fear is largely unknown. Prof. Wang Liping and his colleagues Zhou Zheng and Liu Xuemei […]

Scientists discover complex connections between social dynamics and diseases

Large gatherings—from music festivals to religious pilgrimages to sporting events—have long been known to increase risks of infectious disease outbreaks. Now results from an NSF-funded study led by UC Berkeley researchers associate even small-scale community gatherings with increased transmission of diarrheal diseases. The results are published in the American Journal of Epidemiology. Gatherings at events can create environmental and social […]

Scientists define the role for a rare, influential set of bone marrow cells

Researchers have defined the roles of various cells in the bone marrow that are thought to control the fate of the nearly half million blood cells that develop there each day. Scientists at NYU School of Medicine behind the new work say little had been known about the fraction of cells examined in the study, the “microenvironment” that makes up […]

Scientists find first evidence for necessary role of the human hippocampus in planning

A team of scientists reports finding the first evidence that the human hippocampus is necessary for future planning. Its findings, published in the journal Neuron, link its long-established role in memory with our ability to use our knowledge to map out the future effects of our actions. The results have implications for the way we think about afflictions that affect […]

Scientists identify genetic factors that may cause some people to become obese

Obesity is a major public-health problem in the United States and around the world, with an estimated 650 million people suffering from the condition. One of the biggest challenges of this ever-worsening condition is figuring out why people become obese in the first place, and why some people are more vulnerable to obesity than others. Now, scientists at The Rockefeller […]

Women scientists get less federal funding than men, new study finds

First-time women principal investigator scientists received considerably less funding from the National Institutes of Health (NIH) compared to first-time male principal investigators, even at top research institutions, reports a new study from Northwestern Medicine and the Kellogg School of Management. Previous research showed women receive lower startup funds from their universities to launch their research. This is the first study […]

Scientists identify new disrupted pathway in motor neurone disease

Researchers at the University of Sheffield have identified a new pathway that is disrupted in motor neurone disease (MND), a discovery which could pave the way for new treatments. The ground breaking findings were discovered by converting skin cells to brain cells called astrocytes, and comparing the energy metabolism of cells taken from MND patients versus healthy controls, using a […]

Scientists shed light on processes behind age-related decline in brain structures important for memory

Ageing can cause damage to support cells in the white matter, which in turn may lead to damage in the grey matter of the hippocampus, finds a new study by Cardiff University. The discovery gives researchers a new area to focus on in the search for treatments that can protect cognitive function. Claudia Metzler-Baddeley, from Cardiff University’s Brain Imaging Research […]
