Novel MRI sensor can peer deep into the brain to detect intracellular calcium activity

Calcium is a critical signaling molecule for most cells, and it is especially important in neurons. Imaging calcium in brain cells can reveal how neurons communicate with each other; however, current imaging techniques can only penetrate a few millimeters into the brain.

Invasive surgeries could be avoided with new pacemakers powered by heartbeats

Researchers have developed a small, flexible, elastic skeleton bound to two piezoelectric composites, which uses the electrical activity of the heart for power.

Morning walks could be better than drugs at lowering blood pressure

According to a new study, just half-an-hour of walking in the morning could be as effective as medication at lowering blood pressure.

New cellular atlas could provide a deeper insight into blinding diseases

When it comes to understanding how neurons connect to form circuits in the brain, scientists for decades have turned to the retina of the humble laboratory mouse as an ideal model organism. But as a model for vision and vision-related diseases, mice simply aren't equipped.

Researchers identify origin of immune cell that helps form healthy heart valves

UCLA researchers have identified for the first time the origin of an immune cell that plays a critical role in the formation of healthy heart valves. The findings could pave the way for new treatments for heart valve disorders, which can be caused by congenital defects, aging or disease.

Study: Cancer stem-like cells are maintained by MTHFD2 mitochondrial metabolic enzyme

An increase in the incidence and mortality rate of cancer has been noted worldwide, especially for lung cancer.

Successful testing of multi-organ "human-on-a-chip" could replace animals as test subjects

The replacement of animals as test subjects is one step closer to reality with the successful testing of multi-organ "human-on-a-chip" models to recapitulate the 28-day experiments typically used in animals to evaluate the systemic toxicity of drug and cosmetic compounds.

Innovative compound offers a new therapeutic approach to treat multiple sclerosis

Multiple sclerosis is an autoimmune disease that affects more than 2.3 million people worldwide. This debilitating condition periodically shutters communication between the brain and other parts of the body, resulting in symptoms that range from numbness and tingling in the arms and legs to blindness and paralysis.

Vitamin D supplementation less effective in the presence of obesity, shows study

A new Journal of Bone and Mineral Research study confirms that vitamin D supplementation is less effective in the presence of obesity, and it uncovers a biological mechanism to explain this observation.

News study reanalyzes the effects of noncaloric sweeteners on gut microbiota

There is currently not enough evidence related to the effects of noncaloric sweeteners on appetite, short‑term intake, and risk of suffering from cancer or diabetes, as shown by a study recently published in the scientific journal 'Advances in Nutrition'.

Genetic defect linked to pediatric liver disease identified

Researchers from the University of Colorado Anschutz Medical Campus, in collaboration with several other institutions, have discovered a genetic defect linked to Biliary atresia, the most common pediatric cause of end-stage liver disease, and the leading indication for liver transplantation in children.

Thousands with chronic UTIs are not receiving the treatment they need

Many women may not be receiving the treatment they need because the gold-standard tests for UTIs fail to detect a significant proportion of bacteria.

New sepsis test could save thousands of lives

Researchers have used a biosensor that can quickly identify biomarkers of sepsis and has the potential to save thousands of lives.

Intense exercise, fasting and hormones can enhance waste-protein removal, study shows

The body's ability to adapt to changing conditions and shifting physiologic demands is essential to survival. To do so, each cell must be able to dispose of damaged or unnecessary proteins--a quality-control mechanism critical for cellular performance and for the health of the entire organism.

Johns Hopkins scientists find new compound that may prevent reperfusion injury

In a strategic search, Johns Hopkins scientists created and screened a library of 45,000 new compounds containing chemical elements of widely used immune system suppressants, and say they found one that may prevent reperfusion injury, a tissue-damaging and common complication of surgery, heart attack and stroke.
