New sensor can detect estrogen levels in liquids

Estrogen is a tiny molecule, but it can have big effects on humans and other animals. Estrogen is one of the main hormones that regulates the female reproductive system - it can be monitored to track human fertility and is sometimes administered to livestock like cows and sheep to control the reproductive cycle.

UF Health researcher finds simple way to treat immune-related disorder in mice

A University of Florida Health researcher has found a simple, rapid way to treat an immune-related disorder in mice, an approach that could eventually help multiple sclerosis patients after further research.

Scientists show evidence for exchange of lactate between different brain cells

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

Dopamine measurements provides information crucial for human choice

Virginia Tech Carilion Research Institute scientists have reported measurements of dopamine release with unprecedented temporal precision in the brains of people with Parkinson's disease. The measurements, collected during brain surgery as the conscious patients played an investment game, demonstrate how rapid dopamine release encodes information crucial for human choice.

Microgravity inhibits regenerative and differentiation potential of embryonic stem cells

A study performed on the NASA Space Shuttle Discovery showed that exposure of mouse embryonic stem cells (mESCs) to microgravity inhibited their ability to differentiate and generate most cell lineages, needed for the development of bone, muscle, the immune system, and other organs and tissues.

Finding may lead to better understanding of male genital birth defects

University of Florida Health researchers have identified genes that are disrupted by abnormal hormone signaling at crucial points during development, a finding that may lead to a better understanding of how the most common male genital birth defects arise in humans.

Food smells activate impulse areas of the brain linked with obsessive-compulsive disorder in obese children

The area of the brain associated with impulsivity and the development of obsessive-compulsive disorder is activated in obese children when introduced to food smells, according to a study being presented next week at the annual meeting of the Radiological Society of North America.

Brain protein identifies presence of nerve fiber damage

Physicians and others now recognize that seemingly mild, concussion-type head injuries lead to long-term cognitive impairments surprisingly often. A brain protein called SNTF, which rises in the blood after some concussions, signals the type of brain damage that is thought to be the source of these cognitive impairments, according to a study led by researchers from the Perelman School of Medicine at the University of Pennsylvania, and the University of Glasgow, Glasgow, UK.

High-fat diet appears to prompt immune cells to start consuming connections between neurons

When a high-fat diet causes us to become obese, it also appears to prompt normally bustling immune cells in our brain to become sedentary and start consuming the connections between our neurons, scientists say.

Notre Dame researchers discover compound that speeds up diabetic wound healing

Non-healing chronic wounds are a major complication of diabetes, which result in more than 70,000 lower-limb amputations in the United States alone each year. The reasons why diabetic wounds are resistant to healing are not fully understood, and there are limited therapeutic agents that could accelerate or facilitate their repair.
