Study: No-fat, low-fat dressings don't get most nutrients out of salads Posted: 19 Jun 2012 08:02 PM PDT The vegetables in salads are chock-full of important vitamins and nutrients, but you won't get much benefit without the right type and amount of salad dressing, a new study shows.

Specific bacteria linked to indoor water-damage and mold identified Posted: 19 Jun 2012 08:02 PM PDT Bacterial contamination in water-damaged buildings has been identified as a potential cause of health problems, including infection and respiratory conditions like asthma. An environmental health research team found evidence linking two specific strains of bacteria -- Stenotrophomonas and Mycobacterium -- to indoor mold from water damage.

Hulk smash? Maybe not anymore: Scientists block excess aggression in mice Posted: 19 Jun 2012 08:01 PM PDT Pathological rage can be blocked in mice, researchers have found, suggesting potential new treatments for severe aggression, a widespread trait characterized by sudden violence, explosive outbursts and hostile overreactions to stress.

Adaptable decision making in the brain Posted: 19 Jun 2012 07:52 PM PDT Researchers have discovered how a part of the brain helps predict future events from past experiences. The work sheds light on the function of the front-most part of the frontal lobe, known as the frontopolar cortex, an area of the cortex uniquely well developed in humans in comparison with apes and other primates.

Infants can't distinguish between large and small groups Posted: 19 Jun 2012 09:37 AM PDT Human brains process large and small numbers of objects using two different mechanisms, but infants have not yet developed the ability to make those two processes work together, according to new research.

Inhibitors of shuttle molecule show promise in acute leukemia Posted: 19 Jun 2012 08:29 AM PDT A novel family of experimental agents that blocks a molecule from shuttling proteins out of the cell nucleus might offer a new treatment for people with acute leukemia. The agents, called KPT-SINEs (selective inhibitors of nuclear export), target a transport protein called CRM1. The study shows that these agents inhibit leukemia-cell proliferation, arrest cell division, and induce cell death and differentiation. In an animal model, KPT-SINEs extended survival by 46 percent.

Blogging relieves stress on new mothers Posted: 19 Jun 2012 08:29 AM PDT New mothers who read and write blogs may feel less alone than mothers who do not participate in a blogging community, according to family studies researchers.

Night work may put women's health at risk Posted: 19 Jun 2012 08:29 AM PDT The risk of developing breast cancer is higher among women who have worked at night, according to new research. The study compared the careers of 1,200 women who had developed breast cancer between 2005 and 2008 with the careers of 1,300 other women.

Detector of DNA damage: Structure of a repair factor revealed Posted: 19 Jun 2012 08:28 AM PDT Double-stranded breaks in cellular DNA can trigger tumorigenesis. Researchers have now determined the structure of a protein involved in the repair and signaling of DNA double-strand breaks. The work throws new light on the origins of neurodegenerative diseases and certain tumor types.

Sun exposure and sun-sensitive skin type decreased risk for pancreatic cancer Posted: 19 Jun 2012 07:38 AM PDT High levels of ultraviolet radiation at an individual's birth location, sun-sensitive skin type and a history of skin cancer each decreased risk for pancreatic cancer, according to new study results.

Power of playtime: Single mothers can reduce stress by playing, engaging with children Posted: 19 Jun 2012 07:36 AM PDT A group of researchers is studying ways to help single mothers improve their relationship with their children.

Fishing for answers to autism puzzle Posted: 19 Jun 2012 07:36 AM PDT Fish cannot display symptoms of autism, schizophrenia, or other human brain disorders. However, scientists have shown that zebrafish can be a useful tool for studying the genes that contribute to such disorders.

Scientists discover how key enzyme involved in aging, cancer assembles Posted: 19 Jun 2012 06:32 AM PDT Biochemists have mapped the structure of a key protein-RNA complex that is required for the assembly of telomerase, an enzyme important for both cancer and aging.

New method generates cardiac muscle patches from stem cells Posted: 19 Jun 2012 06:32 AM PDT A cutting-edge method uses stems cells to create heart cells that display activity similar to most people's resting heart rate.

Antibacterials in personal-care products linked to allergy risk in children Posted: 19 Jun 2012 06:29 AM PDT Exposure to common antibacterial chemicals and preservatives found in soap, toothpaste, mouthwash and other personal-care products may make children more prone to a wide range of food and environmental allergies, according to new research.

Get the most from your skin care products: Sequence in which you apply skin care products influences their effectiveness Posted: 19 Jun 2012 06:29 AM PDT Consumers often spend hundreds and sometimes thousands of dollars a year on skin care products in an effort to improve the look of their skin. From anti-aging serums to acne medications, many adults and teens regularly apply medications or treatments to their skin. But does the sequence in which skin care products are applied influence how well the products work? Dermatologists say yes.

Study indicates promise in Huntington's treatment Posted: 18 Jun 2012 04:49 PM PDT A new study shows that the compound Coenzyme Q10 reduces oxidative damage, a key finding that hints at its potential to slow the progression of Huntington disease. The discovery also points to a new biomarker that could be used to screen experimental treatments for this and other neurological disorders.

Olympic broadcasting inequality: Olympics commentary differs based on gender, race and nationality Posted: 18 Jun 2012 01:19 PM PDT Studies show Olympic Games' commentary differs based on gender, race and nationality. Athletes who are white, male and/or American receive more favorable coverage than females, non-Americans and minorities.

Psoriasis increases risk of diabetes, study shows Posted: 18 Jun 2012 01:18 PM PDT Psoriasis is an independent risk for Type 2 Diabetes, according to a new study, with the greatest risk seen in patients with severe psoriasis. Researchers estimate that an additional 115,500 people will develop diabetes each year due to the risk posed by psoriasis above and beyond conventional risk factors.

Too much salt may damage blood vessels and lead to high blood pressure Posted: 18 Jun 2012 01:17 PM PDT Eating a high-salt diet for several years is associated with markers of blood vessel damage. People who have markers of blood vessel damage and eat a high-salt diet are more likely to develop high blood pressure; Therefore, the impact of a high-salt diet is greater on this group of people.
