Scientists say a new male contraceptive could be available within the next 10 years, after they have discovered a way to block sperm transportation following ejaculation. This is according to a study published in the journal Proceedings of the National Academy of Sciences.The researchers, led by Dr. Sab Ventura and Dr.
Our mouths are a delicate balance of good and bad bacteria. When we clean our teeth, the aim is to knock out cavity-causing bacteria, while allowing beneficial oral bacteria to thrive. Now, researchers have developed a sugar-free candy, which contains dead bacteria that bind to bad bacteria, potentially reducing cavities.
Researchers from the University of Alberta in Edmonton, Canada, claim dementia sufferers benefit greatly from regular exercise, demonstrating improvements in cognitive functioning and their ability to perform daily activities.
In past studies, depression, anxiety and psychotic disorders have been associated with an increased risk of coronary heart disease. Now, a new study links a wider range of mental disorders to the condition.
Vitamin D plays an important role in maintaining bone health, but a new study led by University of Kentucky researchers claims that deficiency of this vitamin may cause damage to the brain and other organs.
Researchers from the UK's University of Nottingham and colleagues conducted a new study of the population of Taiwan, where there is a high rate of gout, and found that the condition clusters in families.
It seems that inheritance is not simply about parents passing genes to their offspring. Some inheritable changes in gene activity can be passed on without changing the DNA sequencing, as researchers from Emory University School of Medicine claim that mice can inherit the memory of their ancestor's traumas and display similar responses when faced with the stimuli.
Researchers from Yale University have found that while engaging with social information, children with autism spectrum disorders experienced enhanced brain activity after a single dose of the hormone oxytocin was administered through a nasal spray.Results of their findings are published in the journal Proceedings of the National Academy of Sciences.
A newly defined family of proteins has been analyzed by researchers, who say its control over another class of proteins involved in cell division - CAAX proteins - could have major implications for cancer research. Results of their findings were recently published in the journal Nature.
Researchers from the Columbia University Medical Center claim they are one step closer to generating lung tissue for transplant using a patient's own cells. The study, published in Nature Biotechnology, states that scientists have successfully transformed human stem cells into functioning lung and airway cells.
A new study claims to have ruled out a link between childhood vaccination against varicella (chickenpox) and the increased incidence of herpes zoster (shingles) in adults, according to an article published in the Annals of Internal Medicine.Chickenpox and shingles are both caused by the same virus - the varicella zoster virus (VZV).
Researchers in Canada found that switching off a gene in the cancer stem cells that drive colon cancer stops them from being able to renew themselves. They say their study offers a starting point to treatments that could shut the cancer down.Cancer stem cells are cells that have the ability to differentiate into all the types of cell that exist in that type of tumor.
Children with a particular gene variant who are exposed to air pollution appear to be at a higher risk of developing autism, according to researchers from the Keck School of Medicine at the University of Southern California (USC).
Energy drinks have become a multi-billion dollar industry that continues to grow, yet regulation of this enterprise remains largely unchecked. Now, a new study shows that healthy adults who consume energy drinks have "significantly increased" heart contraction rates an hour later. The research was recently presented at the annual meeting of the Radiological Society of North America (RSNA).
New research being presented at the annual meeting of the Radiological Society of North America (RSNA) in Chicago, IL, this week shows how a highly sensitive type of magnetic resonance imaging (MRI) can reveal the long-term impact of blast-induced brain injuries in soldiers.
Patients suffering acetaminophen poisoning could be helped by a small change in the way the antidote is delivered, say scientists from the University of Edinburgh in the UK.The study, published in The Lancet, shows that using the same antidote, acetylcysteine, over a shorter time period leads to fewer side effects.
Tracking a nation's health can be a painstaking business. But now, a team of researchers from the University of Pittsburgh have brought together and digitized all the weekly surveillance reports of diseases in the US since 1888 into one database.The researchers collated all weekly notifiable disease surveillance tables published between 1888 and 2013 - approximately 6,500 tables.
Delivering medicine directly to the affected area provides direct access to the diseased area. Nanoparticles hold promise as a delivery method but are currently only available in injectable forms. Now, researchers from MIT and Brigham and Women's Hospital have made a breakthrough by finding a way of delivering nanoparticles orally.
The CDC estimates that around 4-6% of children in the US suffer from food allergies. Severe food allergies can lead to anaphylaxis - a reaction that causes swelling and breathing difficulties. Although a serious condition, a new study suggests that a person is more likely to be murdered than die from a food allergy.
As the guilt of an overly indulgent weekend kicks in, the chances are that many individuals are resolving to apply more willpower when it comes to tasty treats. If only there were an implant that could trigger a satiety signal in the body so that the desire to overeat would just disappear.
