Long-living breast stem cells give clues to cancer cells of origin

Researchers in Australia have found that breast stem cells and their "daughters" have a longer life than previously believed. This newly discovered longer lifespan suggests that these cells could carry damage or genetic defects earlier in life that eventually lead to cancer decades later.

Gun-related injuries 'hospitalize 20 children in the US every day'

A UK study that compares teenagers' perceptions of what constitutes antisocial behavior with those of adults - the first to do so - finds they differ significantly.Dr. Susie Hulley, currently at the Institute of Criminology of the University of Cambridge, is the author of the study, which is published in the Journal of Crime Prevention and Community Safety.

Bad version of 'good' cholesterol causes disease

Studies have suggested that a form of so-called good cholesterol, or high-density lipoprotein, can become dysfunctional and instead of protecting against heart disease becomes a promoter of it, actively clogging up and hardening arteries.Now, new research led by the Cleveland Clinic in the US has discovered the molecular process that makes "good" cholesterol start behaving badly.

Leukemia pill 'can melt away' cancer cells

According to the National Cancer Institute, there were an estimated 48,610 new cases of leukemia last year, with 23,720 deaths from the condition. Now, new research suggests that a pill taken twice daily could turn the blood cancer into a treatable disease and allow patients to avoid chemotherapy.

Music therapy improves coping skills in young cancer patients

A new study has found that a form of music therapy, which involves writing song lyrics and producing videos, is beneficial in helping young cancer patients develop coping skills.Being diagnosed with and undergoing treatment for cancer can be a very traumatic experience, especially for young people.

Practicing with a partner improves performance, study shows

We all know the saying, "practice makes perfect." But new research suggests that a skill can benefit from even greater improvement if a person is practicing it with a partner. This is according to a study recently published in the journal Scientific Reports.

Greater experience causes older brains to slow down, study shows

We are all familiar with the saying "older but wiser." And new research may prove this to be true. A new study published in the journal Topics in Cognitive Science suggests that as we age, our brain functions slow down as a result of greater experience, not because of cognitive decline.According to the research team, led by Dr.

Men are more forgetful than women, study shows

Men are frequently accused of forgetting birthdays, wedding anniversaries, and even something as simple as taking the trash out.

High-protein diets may increase risk of kidney disease

High-protein diets, such as the Dukan diet, are currently a popular alternative to the traditional calorie-counting forms of dieting. But scientists at the University of Granada in Spain have shown through tests in rats that a high-protein diet increases the risk of kidney stones and other renal diseases.Dr.

Eye movement speed linked to impulsive decision making

One of the most frustrating things about shopping in a grocery store can be the long lines at the cash register. Do you stand there and wait for the line to go down? Or do you join another line that looks quicker? According to new research, decisions such as this may be dependent on the speed of our eye movements.

Scientists find neuron that controls how much we eat

By activating a neuron in the prefrontal cortex of a mouse's brain, scientists are able to make the mouse eat more. But what could this mean for humans?The influence that different areas of the brain may have over eating behaviors is a contentious debate in neurobiology.

Small fetal size in pregnancy could indicate future heart problems

A study published in the BMJ has linked poor growth in the first 3 months (the first trimester) of pregnancy with poor heart health later in life.The rate of human development is highest during the first trimester of pregnancy, and this is when the cardiovascular and metabolic organs form.

Transmissible dog cancer genome sheds light on cancer evolution

The genome of the world's oldest continuously surviving cancer - an 11,000-year-old genital cancer in dogs that can be transmitted during mating - is helping scientists understand underlying factors that drive cancer evolution in general.The latest study, in which researchers describe the genome and evolution of the cancer, has been published in the journal Science.
