Stress, cortisol and perceptual learning process
Neuroscientists of the Ruhr University Bochum found that stress has adverse impact on our learning process. Usually when we train our senses, we sharpen them and thereby improve our perceptual performance. However during stressful situations we produce a hormone called cortisol, which completely blocks this important ability. These findings are reported in Journal “Psychoneuroendocrinology” Stress…

Research unveils structure of crucial bacterial cell wall protein
Duke University researchers have provided the first close-up glimpse of a protein, called MurJ, which is crucial for building the bacterial cell wall and protecting it from outside attack. The research is published in Nature Structural and Molecular Biology. Researchers at Duke University solved the structure of an enzyme that is crucial for helping bacteria…

Research shows musicians have faster reaction to sensory stimuli
According to a new study by Université de Montréal’s School of Speech-Language Pathology and Audiology, part of UdeM’s medical faculty learning to play musical instrument help elderly to react faster and to stay alerted. The study is published in journal Brain and Cognition. The study shows that musicians have faster reaction times to sensory stimuli than…

Role of Vitamin C in cancer treatment
Vitamin C has a patchy history as a cancer therapy, but researchers at the University of Iowa believe that is because it has often been used in a way that guarantees failure. Most vitamin C therapies involve taking the substance orally. However, the UI scientists have shown that giving vitamin C intravenously and bypassing normal…

Zika virus research: Structure of immature virus revealed
Researchers at Purdue University have determined the high-resolution structure of immature Zika virus, a step toward better understanding how the virus infects host cells and spreads. Purdue researchers have determined the high-resolution structure of the immature Zika virus. This composite image of the surface (left), and cross-sectional region (right), reflect the new findings. Research into…

Tau protein as biomarker for predicting recovery time after concussion
Elevated levels of the brain protein tau following a sport-related concussion are associated with a longer recovery period and delayed return to play for athletes, according to a study published in Journal Neurology. The findings suggest that tau, which can be measured in the blood, may serve as a marker to help physicians determine an…

Chronic headache and Vitamin D deficiency
Vitamin D deficiency may increase the risk of a chronic headache, according to a new study from the University of Eastern Finland. The findings were published in Scientific Reports. The Kuopio Ischaemic Heart Disease Risk Factor Study, KIHD, analyzed the serum vitamin D levels and occurrence of a headache in approximately 2,600 men aged between…

Piperlongumine, chemical from Indian pepper plant inhibits enzyme in cancer cells
UT Southwestern Medical Center scientists have uncovered the chemical process behind anti-cancer properties of a spicy Indian pepper plant called the long pepper, whose suspected medicinal properties date back thousands of years. The study is published in the Journal of Biological Chemistry. Dr. Westover’s lab used X-ray crystallography to create this molecular model of piperlongumine.Credit:…

Effects of telomeres length on stem cells
Ever since researchers connected the shortening of telomeres the protective structures on the ends of chromosomes to aging and disease, the race has been on to understand the factors that govern telomere length. Now, Scientists at the Salk Institute have found that a balance of elongation and trimming in stem cells results in telomeres that…
