New way to diagnose malaria by detecting parasite's waste in infected blood cells

A technique that can detect malarial parasite's waste in infected blood cells has been developed by researchers. "There is real potential to make this into a field-deployable system, especially since you don't need any kind of labels or dye. It's based on a naturally occurring biomarker that does not require any biochemical processing of samples" says one of the senior authors of a paper.

Memory in silent neurons: How do unconnected neurons communicate?

According to a generally-accepted model of synaptic plasticity, a neuron that communicates with others of the same kind emits an electrical impulse as well as activating its synapses transiently. This electrical pulse, combined with the signal received from other neurons, acts to stimulate the synapses. How is it that some neurons are caught up in the communication interplay even when they are barely connected? This is the chicken-or-egg puzzle of synaptic plasticity that a team is aiming to solve.

Wine only protects against CVD in people who exercise

Wine only protects against cardiovascular disease (CVD) in people who exercise, according to results from the a study. Evidence suggesting that mild to moderate consumption of wine protects against cardiovascular disease has been accumulating since the early 1990s. In particular, retrospective studies have found that wine increases levels of HDL, the "good" cholesterol. But until now there has been no long-term, prospective, randomised study comparing the effects of red and white wine on HDL cholesterol and other markers of atherosclerosis.

Drinking tea reduces non-CV mortality by 24 percent

Drinking tea reduces non-cardiovascular mortality by 24 percent, reveals a study in 131,000 people. "Tea has antioxidants which may provide survival benefits. Tea drinkers also have healthier lifestyles so does tea drinking reflect a particular person profile or is it tea, per se, that improves outcomes -- for me that remains an open question. Pending the answer to that question, I think that you could fairly honestly recommend tea drinking rather than coffee drinking and even rather than not drinking anything at all," one researcher said.

Energy drinks cause heart problems, study suggests

Energy drinks can cause heart problems according to research. "So-called 'energy drinks' are popular in dance clubs and during physical exercise, with people sometimes consuming a number of drinks one after the other. This situation can lead to a number of adverse conditions including angina, cardiac arrhythmia (irregular heartbeat) and even sudden death," researchers report.

Batteryless cardiac pacemaker is based on automatic wristwatch

A new batteryless cardiac pacemaker based on an automatic wristwatch and powered by heart motion has been presented by researchers. The prototype device does not require battery replacement.

New horizon in heart failure: Investigational drug poised to change cardiology?

An investigational new heart failure drug could be poised to change the face of cardiology based on Hot Line results. The new agent, known as LCZ696, has already been granted Fast Track status by the FDA -- a designation which can expedite the review of new medicines intended to treat serious or life-threatening conditions. Fast Track designation also allows for rolling submission in the US. "To say that we are excited is an understatement. We are absolutely thrilled," said Dr. one investigator.

Meaningful relationships can help you thrive

Deep and meaningful relationships play a vital role in overall well-being. A new paper provides an important perspective on thriving through relationships, emphasizes two types of support that relationships provide, and illuminates aspects where further study is necessary.

Some women still don’t underststand 'overdiagnosis' risk in breast screening

A third of women who are given information about the chance of ‘overdiagnosis’ through the breast screening programs may not fully understand the risks involved, according to research. Overdiagnosis happens because some breast cancers grow so slowly that it would take more than a lifetime for them to threaten a woman's health. For every life that is saved through screening, researchers estimate that around three women will be overdiagnosed with breast cancer.
