Now researchers can follow the hectic life inside a cell Posted: 14 Mar 2016 08:11 AM PDT Living cells are constantly on the move. They move around and divide, and they are responsible for transporting molecules around inside themselves. Now researchers have developed a method that makes it possible to become a spectator at this hectic traffic. The method is of particular importance for disease research.

Exercise helps young people with psychosis symptoms, study shows Posted: 14 Mar 2016 07:18 AM PDT The long-term prospects for young people who are diagnosed with psychosis are typically poor, with high rates of relapse, unemployment and premature death. The antipsychotics they are prescribed also cause rapid weight-gain. Now investigators report that an exercise program has dramatically reduced symptoms among young people with first-episode psychosis.

Potential new therapeutic target for hypertension may offer less side effects Posted: 14 Mar 2016 07:17 AM PDT The recent discovery of a molecule that rescues damaged blood vessels, yet preserves healthy vessels, could serve as a springboard for a new pharmaceutical therapy with fewer side effects for hypertension, report scientists.

Breast cancer: ROBO1 helps cells put up stiff resistance Posted: 14 Mar 2016 07:16 AM PDT A protein called ROBO1 may delay the progression of breast cancer, according to a new article. The study identifies a signaling pathway that may protect breast cells from the tumorigenic effects of stiff extracellular matrices.

Novel nano biosensor developed for rapid detection of flu virus Posted: 14 Mar 2016 06:17 AM PDT A novel nano biosensor for rapid detection of flu and other viruses has been developed by researchers. The new invention utilizes an optical method called upconversion luminescence resonance energy transfer (LRET) process for ultrasensitive virus detection.

Sedentary behavior increases with age even in active children Posted: 14 Mar 2016 06:11 AM PDT Sedentary behaviour increases in children between the ages of nine and 12 – even if they are otherwise physically active, according to new research.

Rapid response for inflammation control in songbirds' brains could lead to therapies in humans Posted: 14 Mar 2016 06:10 AM PDT A biological process in the brains of zebra finches shows that the songbirds respond quickly to trauma and are capable of controlling the natural inflammation that occurs to protect the brain from injury. Understanding the process well enough could lead to therapies in humans to control inflammation and hasten recovery from brain injury such as stroke, says a neuroscientist.

Beta-blockers could reduce the risk of COPD exacerbations Posted: 14 Mar 2016 06:10 AM PDT Beta-blockers could be used to reduce the risk of chronic obstructive pulmonary disease (COPD) exacerbations, according to new findings.

New 'AsthmaMap' could redefine disease and personalize treatment for patients Posted: 14 Mar 2016 06:10 AM PDT A new digital 'map' detailing different mechanisms that contribute to the development of asthma could help researchers redefine the disease. The map works by dividing asthma into different subgroups in order to allow personalized treatment more targeted to the type of asthma patients live with.

How a bad night's sleep might worsen cancer development Posted: 14 Mar 2016 06:09 AM PDT Recent studies have indicated that patients with sleep apnea may be associated with worse cancer outcomes. Now a new animal study uncovers a possible mechanism which may underlie this link.

Can we predict aggressiveness of prostate cancer before surgery with a blood test? Posted: 14 Mar 2016 05:50 AM PDT Prostate cancer is the most common male cancer, with 400,000 new cases every year in Europe. The success of surgery depends on a variety of factors.
