Synthetic sperm protein raises the chance for successful in vitro fertilization Posted: 30 Sep 2014 08:32 AM PDT Having trouble getting pregnant -- even with in vitro fertilization? Here's some hope: A new research report explains how scientists developed a synthetic version of a sperm-originated protein which induced embryo development in human and mouse eggs similar to the natural triggering of embryo development by the sperm cell during fertilization.

Adolescent exposure to THC may cause immune systems to go up in smoke Posted: 30 Sep 2014 08:31 AM PDT When it comes to using marijuana, new research involving mice suggests that just because you can do it, doesn't mean that you should. That's because a team of scientists have found that using marijuana in adolescence may do serious long-term damage to the immune system.

Alcohol makes smiles more 'contagious,' but only for men Posted: 30 Sep 2014 06:06 AM PDT Consuming an alcoholic beverage may make men more responsive to the smiles of others in their social group, according to new research. The findings suggest that, for men, alcohol increases sensitivity to rewarding social behaviors like smiling, and may shed light on risk factors that contribute to problem drinking among men.

Safer than silver: Antibacterial material made with algae Posted: 30 Sep 2014 06:03 AM PDT Consumers concerned about safety of silver ions in antibacterial and odor-free clothing will soon have a proven safe alternative thanks to ultra-thin thread and a substance found naturally in red algae.

Development models put to the test: Low birth weight children are particularly vulnerable to environmental influences Posted: 30 Sep 2014 06:03 AM PDT Low birth weight children are more vulnerable to environmental influences than infants born with normal weight. When brought up with a great deal of sensitivity, they will be able to catch up in school, but on average they will not become better students than normal birth weight children. This result, provided by an international psychologist team, has confirmed the so-called diathesis-stress model of development for low birth weight populations.

Asthma symptoms kicking up? Check your exposure to air pollution Posted: 30 Sep 2014 06:01 AM PDT A woman who suffers from asthma has been the subject of a recent case study. She, along with her doctor, realized that by changing her bike route to and from work every day, she can cut down on the pollution to which she's exposed, thereby improving her asthma symptoms.

Childhood asthma linked to lack of ventilation for gas stoves Posted: 29 Sep 2014 03:05 PM PDT Parents with children at home should use ventilation when cooking with a gas stove, researchers are recommending, after a new study showed an association between gas kitchen stove ventilation and asthma, asthma symptoms and chronic bronchitis.

Use of broad-spectrum antibiotics before age 2 associated with obesity risk Posted: 29 Sep 2014 03:00 PM PDT The use of broad-spectrum antibiotics by children before the age of 24 months was associated with increased risk of obesity in early childhood, a study concludes. The authors used electronic health records spanning from 2001 to 2013 from a network of primary care clinics. All children with annual visits at ages 0 to 23 months, as well as one or more visit at ages 24 to 59 months were enrolled. The final group included 64,580 children. Children were followed-up until they were 5 years old.

Feeling fatigued while driving? Don't reach for your music Posted: 29 Sep 2014 09:39 AM PDT Drinking caffeinated beverages and listening to music are two popular fatigue-fighting measures that drivers take, but very few studies have tested the usefulness of those measures. New research evaluates which method, if either, can successfully combat driver fatigue.

New method to motivate students to reduce energy consumption Posted: 29 Sep 2014 07:53 AM PDT Energy consumption can be reduced significantly by students if they can see the amount of energy they are using in real-time and are motivated by their peers to save energy, a study has shown.

Who are the men, boys suffering from anorexia? Posted: 29 Sep 2014 07:51 AM PDT The current state of knowledge about anorexia in men and boys has been the focus of recent study. "Our results show that certain particularities can be identified in males, especially related to personality, gender identity, and sexual orientation", says an author of a new study on the topic.

How career dreams are born Posted: 29 Sep 2014 07:51 AM PDT A new study shows just what it takes to convince a person that she is qualified to achieve the career of her dreams. Researchers found that it's not enough to tell people they have the skills or the grades to make their goal a reality. Instead, many people need a more vivid and detailed description of just how pursuing their dream career will help make them successful.

After-school exercise program enhances cognition in 7-, 8- and 9-year-olds Posted: 29 Sep 2014 06:05 AM PDT A nine-month-long, randomized controlled trial involving 221 prepubescent children found that those who engaged in moderate-to-vigorous physical activity for at least 60 minutes a day after school saw substantial improvements in their ability to pay attention, avoid distraction and switch between cognitive tasks, researchers report.
