Florence, Italy - 23 May 2016: The flu jab is associated with a reduced risk of hospitalisation in patients with heart failure, according to research presented today in a late breaking trial session at Heart Failure 2016 and the 3rd World Congress on Acute Heart Failure.1

The study in about 60 000 patients ends the controversy over influenza vaccination in heart failure patients and provides more robust evidence for current recommendations.

Professor Kazem Rahimi, Deputy Director of The George Institute for Global Health, University of Oxford, UK, said: "Many guidelines recommend that elderly patients and those with co-morbidities including heart failure should have annual flu vaccinations to reduce the risk of adverse events."

Barcelona, Spain: Obesity is on the rise throughout the world, and in some developed countries two-third of the adult population is either overweight or obese. This brings with it an increased risk of serious conditions such as heart disease, stroke, cancer and osteoarthritis. Many of these conditions do not appear to affect the parts of the body where the excess fat accumulates, but rather to involve body systems that are remote from the fat accumulation. Now an international group of scientists has taken an important step towards understanding the links between obesity and the related, yet physically distant, diseases it causes, the annual conference of the European Society of Human Genetics will hear today.

Every day humans and animals face ambiguous circumstances. If we become sick after eating, we blame the food; however, if we then fall ill without having eaten that food, the causal link becomes ambiguous. New findings from the RIKEN Brain Science Institute in Japan and New York University reveal where and how such ambiguous associations are processed in the brains of rats.

In Japan, where the suicide rate is quite high but guns are banned, they use rope. So it is accurate to state that rope ownership is closely tied to suicide rates in that country.

Using that same methodology, it is easy to do the same with guns and suicide. States with higher estimated levels of gun ownership had higher incidents of gun-related suicides, according to a new paper in the American Journal of Public Health which covers 33 years, from 1981 to 2013, and the authors claims is the most comprehensive analysis of the association between gun ownership and gender-specific suicides rates among the 50 U.S. states. 

Tempe, Ariz. -- Evolution can be an emotionally charged topic in education, given a wide range of perspectives on it. Two researchers from Arizona State University are taking an in-depth look at how college professors handle it.

In a first-of-its kind study, scientists from ASU School of Life Sciences have found that a majority of professors teaching biology in Arizona universities do not believe that helping students accept the theory of evolution is an instructional goal. In fact, a majority of study participants say their only goal is to help students understand evolution.

RICHLAND, Wash. - Like the poet, microbes that make methane are taking chemists on a road less traveled: Of two competing ideas for how microbes make the main component of natural gas, the winning chemical reaction involves a molecule less favored by previous research, something called a methyl radical.

Reported today in the journal Science, the work is important for understanding not only how methane is made, but also how to make things from it.
