More competitive games produced greater levels of aggressive behavior than less competitive games, no matter how much violence was in the games.

In one experiment, lead author Paul J.C. Adachi, M.A., a PhD candidate at Brock University in Canada, had 42 college students (25 men, 17 women) play one of two video games, “Conan” or “Fuel,” for 12 minutes. “Conan” is a violent game in which the main character battles for survival using swords and axes. “Fuel” is a non-violent racing game.

In a pilot study, both games were rated evenly in terms of competitiveness, difficulty and pace of action, but differently in terms of violence. After participants finished playing the game, they were told they were going to take part in a separate food tasting study.

Participants had to make up a cup of hot sauce for a “taster” who they were told did not particularly like hot or spicy food. The participants could choose from one of four different hot sauces (from least hot to most hot) for the taster to drink.

The authors found that there was no significant difference in the intensity and amount of the hot sauces prepared by the participants who played “Conan” and those who played “Fuel.” The authors concluded that, in this study, video game violence alone was not sufficient to elevate aggressive behavior.

Although a number of studies have looked at gender differences in suicide risk, few have examined gender differences in suicide methods. Understanding gender differences in suicide methods has important implications for suicide prevention efforts.

Callanan and Davis examined the medical examiner’s files of 621 suicide cases in Summit County, Ohio in the US, covering a 10-year period (1997-2006). They found that women were significantly less likely than men to use suicide methods with the potential to disfigure the face or head. Indeed, men were nearly twice as likely as women to have used such methods.

The researchers also found that for every one-unit increase in blood alcohol level, the odds of using a disfiguring method increased by nearly 10 percent. Gender, age, stressful life events and prior suicide attempts all predicted the use of methods that disfigure the face and head.

The authors conclude: “To suggest that women are less likely to shoot themselves in the face or head because they are more concerned about their appearance than men is to minimize the significance of the act of suicide. What we do know is that those experiencing stressful life events are at far greater risk of employing an especially lethal method of suicide than those not experiencing such events.”

It concluded that men with fast intensity cycling survived 5.3 years longer, and men with average intensity 2.9 years longer than men with slow cycling intensity. For women the figures were 3.9 and 2.2 years longer, respectively.

Current recommendations have prescribed that every adult should accumulate 30 minutes or more of moderate physical activity in leisure time, preferably every day of the week.

According to Prof Schnor, “this study suggests that a greater part of the daily physical activity in leisure time should be vigorous, based on the individuals own perception of intensity.”

The study has been presented at the ESC Congress 2011.

The experts found Ribena squash promotes its vitamin C content without making clear that 90 per cent of the vitamin content is artificially added to the drink because it contains such a small amount of fruit juice.

Fruit Shoot Hydro doesn’t contain any fruit at all, while Still Vimto and Ribena have only 5 per cent fruit and contain more added sugar than fruit.

A Vimto marketing campaign emphasises the drink’s raspberry content, says the report, despite the fact that raspberry juice makes up just 0.1 per cent of its ingredients, equivalent to about ten drops in a 500ml bottle.

Less than one-eighth of Capri-Sun drink is fruit, and it has significant added sugar, says the report.

The report, called Soft Drinks, Hard Sell, comes after the soft drinks industry reported its highest growth rate in seven years in 2010, with UK consumption reaching 14.6billion litres annually.

“Our survey found some truly misleading marketing blatantly used to drive sales and increase children’s soft drinks consumption, which contributes to tooth decay and the UK’s record rates of childhood obesity,” the Daily Mail quoted The Children’s Food Campaign’s Clare Panjwani, who wrote the report, as saying.

Within that group, “we believe that there were 83 deaths,” said commission member Stephen Hauser.

Among the 1,300 exposed to STDs, “under 700 received some form of treatment as best as could be documented,” Hauser added.

US President Barack Obama created the commission last year, after news of the experiments came to light.

Obama personally apologized to Guatemalan President Alvaro Colom in October before ordering a thorough review of what happened, and Secretary of State Hillary Clinton described the experiments as “clearly unethical.”

The Guatemalan study, which was never published, came to light in 2010 after Wellesley College professor Susan Reverby stumbled upon archived documents outlining the experiment led by controversial US doctor John Cutler.

Cutler and his fellow researchers enrolled 1,500 people in Guatemala, including mental patients, for the study, which aimed to find out if penicillin could be used to prevent sexually transmitted diseases.

Initially, the researchers infected female Guatemalan commercial sex workers with gonorrhea or syphilis, and then allowed them to have unprotected sex with soldiers or prison inmates.

Cutler also was involved in a highly controversial study known as the Tuskegee Experiment in which hundreds of African-American men with late-stage syphilis were observed but given no treatment between 1932 and 1972.

The Guatemalan president has called the 1946-48 experiments conducted by the US National Institutes of Health “crimes against humanity” and ordered his own investigation.

The research shows that the amount tobacco exposure during the entire life significantly correlates with the thickness of carotid arterial walls (an index of atherosclerosis) in both genders. However, the impact is more than doubled in women than in men. Similarly, the effect of the number of cigarettes smoked per day on the progression of the disease over time is more than five-fold in women than in men. These associations are independent from other factors that may affect atherosclerosis, such as age, blood pressure, cholesterol level, obesity and social class.

Elena Tremoli, Professor of Pharmacology at the University of Milan, Italy, and scientific director of the Monzino Cardiology Centre in Milan who led the study, says: “This is a particular relevant finding, especially in view of the fact that educational campaigns carried out in the last years have been less successful in reducing the number of smokers in women than in men”.

According to WHO, while in most European countries a significant proportion of men has quit smoking, in many countries (e.g. Italy and Finland) the percentage of women smokers remained roughly constant in the last three decades, whereas in others (France, Spain) it even increased.

“The reasons for the stronger effect of tobacco smoke on women’s arteries are still unknown, but some hints may come from the complex interplay between smoke, inflammation and atherosclerosis”, says Prof. Tremoli.

That’s the premise behind an unusual symposium occurring here today at the 242nd National Meeting Exposition of the American Chemical Society (ACS), the world largest scientific society. Entitled “Empowering Tomorrow’s Science Super Heroes,” it opens a discussion on how to give scientists a touch of the panache of the stock comic book and Hollywood characters who worked for the public good.

“We are seeking ways to equip scientists to better communicate and connect with the rest of society,” said Donna J. Nelson, Ph.D., an organizer of the session. It is among events at the meeting, which includes more than 7,500 scientific presentations, initiated by Nancy B. Jackson, Ph.D., ACS president. “The well-equipped superhero and superheroine has the communications skills to explain their work and the wonder and importance of science in an understandable way,” Nelson explained. “They have an awareness of public policy, how science connects with societal issues and even the ability to use a bit of humor.”

Nelson, who is with the University of Oklahoma and the Massachusetts Institute of Technology (MIT), said those skills add up to super-hero-level leaders who can inspire students, build public support for science and engage in key public policy decisions. Three of her models for science superheroes are the late Richard E. Smaley, Ph.D.; Harold Kroto, Ph.D.; and Robert F. Curl, Ph.D., who shared the 2005 Nobel Prize in Chemistry. “All three have been great organizers and leaders with superb social skills and just the kind of people to get kids interested in a career in science,” Nelson said.
