Scientists make pure precursor liver and pancreas cells from stem cells

A new study published in the journal Cell Stem Cell, describes how scientists have developed a way of producing highly sought populations of a pure tissue-specific cell from human pluripotent stem cells.Human pluripotent stem cells (hPSCs) are precursor cells than can produce over 200 distinct cell types in the human body.

Food bug toxin may trigger multiple sclerosis

New research presented at a scientific meeting adds to a growing body of evidence that a toxin produced by a common food bug may trigger multiple sclerosis, an inflammatory disease of the central nervous system.Dr.

Premature babies 'at higher risk for asthma'

The World Health Organization estimates that 15 million babies are born premature every year, which means they are born before 37 weeks. But new research suggests that risks are higher than previously thought for preterm babies to develop childhood asthma, compared with their full-term counterparts.

IVF: risks may outweigh benefits, say experts

The first baby was born using in vitro fertilization in 1981. From then until 2003, more than 1 million babies were born using the treatment, and this increased to 2 million by 2005. Now, a new analysis published in the BMJ suggests that in vitro fertilization may be overused, and the risks of the treatment could possibly outweigh the benefits.

New 'whole-body scan' could improve bone marrow cancer treatment

Developments in magnetic resonance imaging have led to a pioneering new technique that scans the patient's entire body. This new kind of scan could be useful for showing doctors where a patient's bones may be affected by cancer.Magnetic resonance imaging - or MRI - is an imaging test that uses magnets and radio waves to create pictures of the body.

Breast cancer survivors benefit from yoga

A new US study finds that yoga can benefit breast cancer survivors by reducing fatigue and inflammation. While yoga has many components, the researchers believe breathing and meditation probably had the biggest impact.

Scientists discover why a protein is crucial to healthy cell growth

Researchers from Penn State University and the University of California have discovered how a protein is crucial for the growth of healthy cells in mammals. This is according to a study published in the journal Proceedings of the National Academy of Sciences.

Compounds in exhaled breath may detect early lung cancer

Of all cancers, lung cancer is the biggest killer in both men and women. According to the American Lung Association, it causes more deaths than colon, breast and prostate cancer combined. Diagnosing the disease can involve a number of tests, but scientists have discovered that specific compounds in exhaled breath may be used to diagnose the disease in its early stages.

Disrupted sleep speeds up cancer

Researchers in the US found of two groups of mice given the same cancer-inducing treatment, the group whose sleep was disrupted developed larger, more aggressive tumors than the well-rested mice.

Scientists discover deadly plague cause

The Justinian plague and the Black Death are two of the deadliest plagues in human history - both responsible for killing almost half of the European population. Now, an international research team has discovered that both plagues were caused by different strains of the same bacterium.This is according to a study recently published online in The Lancet Infectious Disease.

Vitamin D deficiency in pregnancy 'increases preeclampsia risk'

Research led by investigators from the University of Pittsburgh Graduate School of Public Health suggests that women who have a vitamin D deficiency in the first 26 weeks of pregnancy are more likely to develop severe preeclampsia. This is according to a study recently published in the journal Epidemiology.

A byproduct of the pesticide DDT increases risk of Alzheimer's

The controversial pesticide DDT was banned in the US in 1972 but is still used in the agricultural industries of some countries. Now, a study published in the Journal of the American Medical Association Neurology has found a link between having levels of a DDT byproduct in the blood and an increased risk of Alzheimer's disease.

A new initiative improves asthma control in teenagers

What is believed to be the first quality improvement initiative focusing exclusively on asthmatic teenagers - conducted by researchers at Cincinnati Children's Hospital Medical Center in Ohio - has reported significant improvements in asthma outcomes.

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'

New research suggests that around 20 children in the US are hospitalized every day after being injured by firearms, and approximately 6% of these children die from their injuries. This is according to a study published online in the journal Pediatrics.The research team, led by Dr.

Older people more likely to regard public behavior as antisocial

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.
