New genomic analysis promises benefit in female urinary incontinence

(European Society of Human Genetics) Urinary incontinence in women is common, with almost 50 percent of adult women experiencing leakage at least occasionally. Genetic or heritable factors are known to contribute to half of all cases, but until now studies had failed to identify the genetic variants associated with the condition.

Obesity can cause cardiovascular ill-health, even in the young

(European Society of Human Genetics) Higher than normal body mass index (BMI) is known to lead to cardiovascular ill-health in mid-to-late life, but there has been limited investigation of its effect in young, apparently healthy, adults. Researchers have now shown that having a higher BMI can cause worse cardiovascular health in those aged as young as 17.

Open-access genetic screening for hereditary breast cancer is feasible and effective

(European Society of Human Genetics) Offering open-access genetic testing for the inherited breast cancers BRCA1 and 2 to Ashkenazi women unaffected by cancer, regardless of their family history, enables the identification of carriers who would otherwise have been missed.

Mind-controlled device helps stroke patients retrain brains to move paralyzed hands

(Washington University School of Medicine) Stroke patients who learned to use their minds to open and close a plastic brace fitted over their paralyzed hands gained some ability to control their own hands when they were not wearing the brace, according to a new study from Washington University School of Medicine in St. Show More Summary

Losing sleep over climate change

(University of California - San Diego) UC San Diego study of US data suggests a sleep-deprived planet by century's end. Researchers show that unusually warm nights can harm human sleep and that the poor and elderly are most affected. Rising temperatures will make sleep loss more severe.

Why communication is vital -- even among plants and funghi

(University of Cambridge) A plant protein vital to chemical signalling between plants and fungi has been discovered, revealing more about the communication processes underlying symbiosis. Understanding this important relationship could have major consequences for developing more efficient and sustainable agricultural practices around the world.

Dramatic shift in gut microbes and their metabolites seen after weight loss surgery

(Arizona State University) A new study compares the two most common surgical therapies for obesity, known as Roux-en-Y gastric bypass (RYGB), and laparoscopic adjustable gastric banding (LAGB). The results demonstrate that RYGB -- the...Show More Summary

High levels of PFOA found in mid-Ohio River Valley residents from 1991 to 2013

(University of Cincinnati Academic Health Center) New research from the University of Cincinnati reveals that residents of the mid-Ohio River Valley had higher than normal levels of perfluorooctanoic acid (PFOA) based on serum samples collected over a 22-year span. Show More Summary

Dog skull study reveals genetic changes linked to face shape

(University of Edinburgh) A study of dog DNA has revealed a genetic mutation linked to flat face shapes such as those seen in pugs and bulldogs.

Venetian physician had a key role in shaping early modern chemistry

(University of Exeter) Newly discovered notes show for the first time the Venetian doctor who invented the thermometer and helped lay the foundations for modern medical treatment also played a key role in shaping our understanding of chemistry.

Scientists identify protein linked to chronic heart failure

(Rockefeller University Press) Researchers in Japan have identified a receptor protein on the surface of heart cells that promotes chronic heart failure. The study, 'Corticotropin releasing hormone receptor 2 exacerbates chronic cardiac...Show More Summary

Knowledge gap on the origin of sex

(Lund University) There are significant gaps in our knowledge on the evolution of sex, according to a research review on sex chromosomes from Lund University in Sweden. Even after more than a century of study, researchers do not know enough about the evolution of sex chromosomes to understand how males and females emerge.

USDA invests $17.7 million in plant health and production workforce

(National Institute of Food and Agriculture ) The US Department of Agriculture's (USDA) National Institute of Food and Agriculture (NIFA) today announced 54 grants totaling more than $17.7 million for plant research that helps optimize crop production, mitigate disease, and increase yield.

Georgia State receives $2.3 million renewal grant to study enzyme in diabetic vascular diseases

(Georgia State University) Dr. Ming-Hui Zou, director of the Center for Molecular & Translational Medicine and a Georgia Research Alliance Eminent Scholar in Molecular Medicine, has renewed a four-year, $2.3 million federal grant to study the role of an enzyme in causing diabetic vascular diseases and the molecular mechanism that leads to these diseases.

Water forms 'spine of hydration' around DNA, group finds

(Cornell University) How water relates to and interacts with biological systems -- like DNA, the building block of all living things -- is of critical importance, and a Cornell University group has used a relatively new form of spectroscopy to observe a previously unknown characteristic of water.

Why this IndyCar driver is outpacing diabetes

(Michigan State University) New Michigan State University research is the first to help a professional race car driver with diabetes improve his performance during competition, helping him capture two top-5 finishes at the Indianapolis 500.

In fruit fly and human genetics, timing is everything

(University of North Carolina Health Care) Using fruit flies, UNC-Chapel Hill researchers discovered a cascade of molecular signals that program gene activity to drive the fly from one stage of maturation to the next, like a baby turning into an adult. Show More Summary

Researchers find crucial clue to manipulating reproduction in plants

(University of California - Riverside) A team of researchers, led by a UC Riverside plant cell biologist, has for the first time identified a small RNA species and its target gene that together regulate female germline formation in plants -- crucial knowledge for manipulating plant reproduction in order to improve agriculture. Show More Summary

New hair growth mechanism discovered

(University of California - San Francisco) In experiments in mice, UC San Francisco researchers have discovered that regulatory T cells (Tregs; pronounced 'tee-regs'), a type of immune cell generally associated with controlling inflammation, directly trigger stem cells in the skin to promote healthy hair growth. Show More Summary

New drug therapy could improve brain function and life expectancy of ALS patients

(American Associates, Ben-Gurion University of the Negev) The Ben-Gurion U. researcher successfully redesigned a portion of MabThera, an FDA-approved drug used to treat certain autoimmune diseases and types of cancer, into a new molecule to treat ALS. Show More Summary
