It is widely known that a lack of sunlight can sometimes cause a deficiency in vitamin D. But how does a lack of this vitamin affect athletes who train indoors, especially during the winter months? To find out, researchers in the UK studied vitamin D-deficient ballet dancers and observed whether supplementation helped.
Young women approaching puberty could reduce their risk of breast cancer if they avoid high-fat diets, researchers from Michigan State University claim.
A new report from children's charity UNICEF has revealed that more than 850,000 infants have been saved from contracting HIV since 2005 in low- and middle-income countries, and that new adolescent infections could be halved by 2020 with more focus on interventions.
A new device shows that tongue piercings can be more than just an expression of one's style. They can also help those who have lost the use of their arms and legs move. In a recent clinical trial, the device, called the Tongue Drive System, performed much better than the most widely used system.
New research from Lund University in Sweden suggests that a new aggressive strain of HIV develops more rapidly into AIDS than other current strains.From first infection with HIV to developing AIDS can be as short as 5 years - the shortest known for HIV-1 types - say the researchers.The new strain is a "recombinant" virus - a cross of two viruses that meet in an infected person.
Bone grafts could one day incorporate sea coral more extensively, thanks to a small clinical study that found refining its properties makes it more compatible and degradable than a currently used derivative.Dr.
A new animal study suggests that children of obese mothers could reduce their risk of developing negative health effects linked to obesity by exercising during childhood. This is according to a study published in the American Journal of Physiology - Regulatory, Integrative and Comparative Physiology.
Gone are the days of teenagers being content with climbing trees and playing basketball in their free time. Nowadays, they are more likely to be found playing video games. But new research suggests that teenagers who play violent video games are more likely to cheat, experience increased aggression and have reduced self-control.
Brain cancer is one of the most common causes of cancer death in the US population. Current methods can diagnose the cancer within 2 to 3 days, but researchers say they have created a new technique in which the disease could be diagnosed in just half an hour.Brain cancer is defined as one or more cancerous tumors within the brain or central spine canal.
New research suggests that pregnant women who have pre-existing diabetes are significantly more likely to experience stillbirths or death of their infant after birth. This is according to a study published in the journal Diabetologia.
In a study involving mice, researchers have found a gene that regulates alcohol consumption. When this gene is faulty, the mice are prompted to drink excessive amounts of alcohol, suggesting a potential genetic component at play in human alcohol consumption.
Obesity prevalence is the highest it has ever been. The Centers for Disease Control and Prevention (CDC) states that more that one-third of American adults are affected. And with the increase in obesity comes an increase in the number of weight loss surgery procedures. But how safe are the procedures, and do the benefits outweigh the risks?
Using a powerful laser imaging technique, a study led by the University of Cambridge in the UK shows how tiny pieces of a protein linked with Alzheimer's Disease could be the start of a process that leads to the onset and spread of the disease. The researchers also cautiously suggest the finding offers a plausible explanation as to why head injuries are linked to Alzheimer's.
A new study by over 60 researchers from 26 countries suggests that the number of people who died in the 2009 global H1N1 "swine flu" outbreak is much higher than official figures show.
Scientists say they have discovered that breathing low oxygen levels in short bursts could help improve the mobility of people with spinal cord injuries. This is according to a study published in the journal Neurology.Spinal cord injury (SCI) is defined as disruption to the nerves attached to the spinal cord in the back.
Researchers from the University of South Carolina say that tetrahydrocannabinol, the principal constituent of marijuana, may have another medical use - treating those with autoimmune disorders.Tetrahydrocannabinol (THC) is known to have analgesic effects so can be used to treat pain.
As millions of Americans prepare to sit down for Thanksgiving dinner, an interesting new study from the UK reveals that people who live in well-heated homes are not as likely to be obese or have a high body mass index, compared with individuals who keep their houses cooler.
Breast cancer will likely affect one in eight women at some point during their lifetime, and the risks increase with age. However, the risk is not the same for all women in any given age group.
Researchers from the University of Montreal have discovered that the amino acid asparagine is essential for healthy brain development in children. They have also discovered that while other organs in the body can draw asparagine from dietary sources, the brain needs the local synthesis of the amino acid to function properly.Senior co-author of the study Dr.
Not all cancers are due to genetic damage, say researchers in the UK. Some forms of the disease may be caused by older cells circumventing the switch that directs them to stop growing, which suggests cancers later in life may be due to the way our cells age.
