Talking about sex to teenagers

Sex is one of the most difficult topics a parent can bring up with an adolescent, but a new study finds that parents who are taught specific communication skills can more readily tackle these conversations and sustain them over time.

Researchers find six genes that, when mutated, contribute to autism

The hunt for gene mutations that contribute to autism has proceeded slowly, largely because autism encompasses a spectrum of diseases. Just as its symptoms vary widely among individuals, so do the genetic mutations that cause them.

Malaria prevention in schools reduces anaemia and improves educational potential in Kenyan school children

Providing preventive treatment for malaria, given once per term, dramatically reduces rates of malaria infection and anaemia among schoolchildren, and significantly improves their cognitive ability, according to new research published today in the Lancet.

Study reveals potential reasons for truancy and school fear

A questionnaire of Swiss schoolchildren has revealed the extent of truancy and school fear. The research, published in BioMed Central's open access journal Child and Adolescent Psychiatry and Mental Health, links truancy and school fear to life events, parental behaviour and school environment.

New York school agrees to admit diabetic students

The Department of Justice announced today that Raynor Country Day School, in Long Island, N.Y., has entered into a settlement agreement with the United States to resolve two complaints filed by parents of children with diabetes who were turned down for enrollment in the school's day camp last summer.

Proof-of-concept that purified muscle stem cells can be used in therapy

By injecting purified stem cells isolated from adult skeletal muscle, researchers have shown they can restore healthy muscle and improve muscle function in mice with a form of muscular dystrophy. Those muscle-building stem cells were derived from a larger pool of so-called satellite cells that normally associate with mature muscle fibers and play a role in muscle growth and repair.

Researchers discover that learning suffers if brain transcript isn't transported far out to end of neurons

Neuroscientists at Georgetown University Medical Center have solved a mystery that lies at the heart of human learning, and they say the solution may help explain some forms of mental retardation as well as provide clues to overall brain functioning.

Common mechanisms may underlie autism's diverse mutations

Many of the seemingly disparate mutations recently discovered in autism may share common underlying mechanisms, say researchers supported in part by the National Institute of Mental Health (NIMH), a part of the National Institutes of Health (NIH). The mutations may disrupt specific genes that are vital to the developing brain, and which are turned on and off by experience-triggered neuronal activity.

An automated wearable artificial kidney

Two researchers from UCLA and the Veterans Affairs Greater Los Angeles Healthcare System have developed a design for an automated, wearable artificial kidney, or AWAK, that avoids the complications patients often suffer with traditional dialysis.

Potential new way to prevent graft-versus-host disease

A new University of Michigan study in mice suggests that a drug recently approved to fight cancer tumors is also able to reduce the effects of graft-versus-host disease, a common and sometimes fatal complication for people who have had bone marrow transplants.

How alcohol impacts heart and stroke risk may differ for men and women

The volume of alcohol consumption may have a significantly different effect on heart and stroke risk in men and women, according to a study of Japanese people published in Stroke: Journal of the American Heart Association.

Researchers identify brain cells related to fear - paves way for more effective PTSD treatments

The National Institute of Mental Health estimates that in any given year, about 40 million adults (18 or older) will suffer from some form of anxiety disorder, including debilitating conditions such as phobias, panic disorders and post-traumatic stress disorder (PTSD). It is estimated that nearly 15 percent of U.S. soldiers returning from Iraq and Afghanistan develop PTSD, underscoring the urgency to develop better treatment strategies for anxiety disorders.

Scientists view tiny fibers of working muscles in live humans with microendoscopy technique

Using an unusual microscope with a tip the size of a needle, Stanford researchers are now able to look at tiny fibers of working muscles in live humans, with minimum discomfort to the patient-a development patients are sure to welcome.

Scientists identify 22 genes that control embryonic stem cell fate

Scientists have identified about two dozen genes that control embryonic stem cell fate. The genes may either prod or restrain stem cells from drifting into a kind of limbo, they suspect. The limbo lies between the embryonic stage and fully differentiated, or specialized, cells, such as bone, muscle or fat.

Australian naturopaths in favour of regulation

Naturopaths are strongly in favour of regulation of their industry, a University of Queensland researcher has found.

Advances in RNA research

RNA, the transporter of genetic information within the cell, has emerged from the shadow of DNA to become one of the hottest research areas of molecular biology, with implications for many diseases as well as understanding of evolution. But the field is complex, requiring access to the latest equipment and techniques of imaging, gene expression analysis and bioinformatics, as well as cross-pollination between multiple scientific disciplines.

Researchers measure movements smaller than one-billionth of a meter in ion channels

Each thought or action sends a million electrical signals pulsing through your body. At the heart of the process of generating these electrical impulses is the ion channel.

UGA discovery could lead to new ways to attack cancers by blocking their ability to grow

Human cancer cells divide and conquer. Unless physicians can control that division with surgery, chemotherapy or radiation, the wildly dividing cells will eventually destroy a person's life.

Novel approach shows potential to become an emergency treatment for heart attack patients

Researchers at The Children's Hospital of Philadelphia have manipulated cell activity that occurs during the interruption of blood flow to strongly protect heart tissue in animal studies. The finding has the potential to become an emergency treatment for heart attack patients, particularly since already existing drugs might be pressed into service to produce the protective effects.

Lipid Association responds to new cholesterol guidelines for kids

When the American Academy of Pediatrics (AAP) issued its recommendation on July 7 regarding the treatment of children with high cholesterol, it generated a strong response from the community of medical professionals and patients. The National Lipid Association (NLA), a group of healthcare professionals who specialize in cholesterol and heart disease issues, believes that the AAP has acted in the interests of patient care by raising the issue of lipid abnormalities in children.
