In one of the first published studies using data from the Health eHeart Study, UCSF researchers have found that people are divided on the cardiovascular benefits of alcohol consumption. And, those who do perceive alcohol as "heart healthy" drink substantially more than their counterparts.
The study is in the Aug. 15 issue of American Journal of Cardiology.
Despite a prevalence of anonymous sperm donation in European countries, the use of the same sperm donor for subsequent conceptions is of paramount importance to those couples needing sperm donation to have children. "We found a marked tendency to favour full genetic bonds where possible," said midwife Sara Somers presenting study results today at the Annual Meeting of ESHRE.
Chimpanzees and bonobos are the two closest living relatives of the human species - the ultimate tool-using ape. Yet, despite being so closely related on the evolutionary tree, wild chimpanzees and bonobos differ hugely in the way they use tools.
Randomized controlled trials must be simplified to sustain innovation in cardiovascular diseases, which are still the biggest killer in Europe, according to the Cardiovascular Round Table (CRT).
The CRT is an independent forum established by the European Society of Cardiology (ESC) and comprised of cardiologists and representatives of the pharmaceutical, device and equipment industries. The group's views are published today in European Heart Journal 1*.
Using Twitter and Google search trend data in the wake of the very limited U.S. Ebola outbreak of October 2014, a team of researchers from Arizona State University, Purdue University and Oregon State University have found that news media is extraordinarily effective in creating public panic.
Because only five people were ultimately infected yet Ebola dominated the U.S. media in the weeks after the first imported case, the researchers set out to determine mass media's impact on people's behavior on social media.
The environmental movement is making a difference - nudging greenhouse gas emissions down in states with strong green voices, according to a Michigan State University (MSU) study.
Social scientist Thomas Dietz and Kenneth Frank, MSU Foundation professor of sociometrics, have teamed up to find a way to tell if a state jumping on the environmental bandwagon can mitigate other human factors - population growth and economic affluence - known to hurt the environment.
It's been around for decades and it's probably in your diet soda - for a little while longer anyway. PepsiCo announced recently it was removing the artificial sweetener aspartame from its Diet Pepsi products in the U.S. starting in August.

So this week, Reactions answers the question, "Is aspartame safe?"
Australia has been hugely successful in reducing the number of people who smoke. Today, 12.8% of people over age 14 smoke on a daily basis, which is nearly half the daily smoking rate in 1991 (24.3%).
African-American adults -- particularly women -- are much more likely to know or be related to someone behind bars than European-Americans, according to the first national estimates of Americans' ties to prisoners.
The research, led by Hedwig Lee, University of Washington associate professor of sociology, reveals the racial inequality wrought by the U.S. prison boom, with potentially harmful consequences to families and communities left lacking social supports for raising children and managing households.
The increasing use of video games is often blamed for children's lack of interest in physical activity, but a study by the University of Tennessee, Knoxville, recently published in the Games for Health Journal suggests that active video games may actually be a source of moderate or intense physical activity in children five to eight years old.
When a new type of drug or therapy is discovered, double-blind randomized controlled trials (DBRCTs) are the gold standard for evaluating them. These trials, which have been used for years, were designed to determine the true efficacy of a treatment free from patient or doctor bias, but they do not factor in the effects that patient behaviors, such as diet and lifestyle choices, can have on the tested treatment.
On June 7th, the English actor Sir Christopher Lee was pronounced dead, after being admitted to the Chelsea and Westminster Hospital for respiratory problems and heart failure. He was 93.
Simply asking the question, "Do you want more pain medication?" resulted in satisfactory pain control in 99 percent of emergency department patients participating in a study. The study of a new evidence-based protocol to treat acute, severe pain in emergency department patients was published online yesterday in Annals of Emergency Medicine ("Efficacy of an Acute Pain Titration Protocol Driven by Patient Response to a Simply Query: 'Do You Want More Pain Medication?'").
The recent case of the retraction of an article on the ability of openly gay canvassers to shift voters' views toward support for same-sex marriage serves in many ways as a cautionary tale both for researchers and the public.
Peer reviews in science, in which independent scientists who are experts on the subject assess the paper, is the current strategy for ensuring quality and control in scientific research and, therefore, it is essential for the academic world. However, a study led by the Portuguese, Catarina Ferreira, uncovers why this system frequently receives harsh criticism about its effectiveness and transparency, and she proposes alternatives to improve it.
