Why can’t we cure the common cold?

The common cold has the twin distinction of being both the world’s most widespread infectious disease and one of the most elusive. The name is a problem, for starters. In almost every Indo-European language, one of the words for the disease relates to low temperature, yet experiments have shown that low temperature neither increases the

Scientists identify mechanism that helps us inhibit unwanted thoughts

Scientists have identified a key chemical within the ‘memory’ region of the brain that allows us to suppress unwanted thoughts, helping explain why people who suffer from disorders such as anxiety, post-traumatic stress disorder (PTSD), depression, and schizophrenia often experience persistent intrusive thoughts when these circuits go awry. We are sometimes confronted with reminders of

Progress on global poverty and disease at risk, Gates says

LONDON, (Reuters) - Proposed United States budget cuts could put in jeopardy great progress in reducing global poverty and disease and lead to 5 million more deaths from AIDS alone, the philanthropist Bill Gates warned on Wednesday. Gates, whose Bill and Melinda Gates Foundation is a major provider of global health and development funding, said

Researchers predicted when cholera epidemic in Yemen would peak

Hokkaido University scientists have developed a new mathematical model which accurately forecasted that a devastating cholera epidemic in Yemen would peak by early July, the 26th week of 2017 and the cumulative incidence would be the order of 700-800 thousand cases. Cholera, which is caused by the bacterium Vibrio cholerae, infects the small intestine through

The Science of Happiness

We all want to be happy, and there are countless ideas about what happiness is and how we can get some. But not many of those ideas are based on science. That’s where this course comes in. “The Science of Happiness” is the first MOOC to teach the ground-breaking science of positive psychology, which explores

Sedentary behavior increases risk of death for frail, inactive adults

Sedentary behaviours are associated with adverse health outcomes in middle-aged and older adults, even among those who exercise. We examined whether the degree of frailty affects the association between sedentary behaviours and higher risk of mortality. RESULTS: We found that for people with low levels of frailty (frailty index score ≤ 0.1), sedentary time was

1 in 12 doctors accepts payment from pharmaceutical companies related to opioids

One in twelve physicians -- and nearly one in five family medicine physicians -- accepted payments from pharmaceutical companies related to opioids, according to a new study out of Boston Medical Center's Grayken Center for Addiction Medicine. This is the first large-scale, national study of industry payments involving opioids and suggests that pharmaceutical companies may

Breakthrough device heals organs with a single touch

COLUMBUS, Ohio – Researchers at The Ohio State University Wexner Medical Center and Ohio State’s College of Engineering have developed a new technology, Tissue Nanotransfection (TNT), that can generate any cell type of interest for treatment within the patient’s own body. This technology may be used to repair injured tissue or restore function of aging

Tiny implantable “seeds” of tissue produce fully functional livers

Many diseases, including cirrhosis and hepatitis, can lead to liver failure. More than 17,000 Americans suffering from these diseases are now waiting for liver transplants, but significantly fewer livers are available. To help address that shortage, researchers at MIT, Rockefeller University, and Boston University have developed a new way to engineer liver tissue, by organizing

One in three cases of dementia preventable

This remarkable fact was part of a report by the first Lancet Commission on Dementia Prevention and Care that was presented at the Alzheimer’s Association International Conference (AAIC) 2017 and published in The Lancet. The report also highlighted the beneficial effects of nonpharmacologic interventions such as social contact and exercise for people with dementia. “There’s been a great

Decline in financing could undermine malaria efforts

Researchers at the University of California, San Francisco Global Health Group suggest that while government funding for malaria elimination has been increasing in many affected countries since 2000, the increase in government financing does not fully bridge the gap from a decline in external funding that emerged in 2010. Lack of funding or inefficient use

Meditation and yoga can ‘reverse’ DNA reactions which cause stress, new study suggests

Mind-body interventions (MBIs) such as meditation, yoga and Tai Chi don’t simply relax us; they can ‘reverse’ the molecular reactions in our DNA which cause ill-health and depression, according to a study by the universities of Coventry and Radboud. The research, published today in the journal Frontiers in Immunology, reviews over a decade of studies

Designer Viruses Stimulate the Immune System to Fight Cancer

Swiss scientists have created artificial viruses that can be used to target cancer. These designer viruses alert the immune system and cause it to send killer cells to help fight the tumor. The results, published in the journal Nature Communications, provide a basis for innovative cancer treatments. Most cancer cells only provoke a limited reaction

‘Exercise-in-a-pill’ boosts athletic endurance by 70 percent

Salk Institute scientists, building on earlier work that identified a gene pathway triggered by running, have discovered how to fully activate that pathway in sedentary mice with a chemical compound, mimicking the beneficial effects of exercise, including increased fat burning and stamina. The study, which appears in Cell Metabolism on May 2, 2017, not only

Artificial Intelligence May Help Diagnose Tuberculosis in Remote Areas

Researchers are training artificial intelligence models to identify tuberculosis (TB) on chest X-rays, which may help screening and evaluation efforts in TB-prevalent areas with limited access to radiologists, according to a new study appearing online in the journal Radiology. According to the World Health Organization, TB is one of the top 10 causes of death

Vaccination gaps lead to dangerous measles outbreaks in Europe

Gaps in vaccination coverage against measles have led to several outbreaks of the highly-contagious disease in Europe in the past year, with both children and young adults affected, health officials said on Monday. During the first two months of 2017, more than 1,500 measles cases were reported from 14 European countries due to "an accumulation

Ebola virus response: experiences and lessons from Sierra Leone

It’s 18 months since Sierra Leone was declared Ebola free after a two-year outbreak that left 4,000 people dead. While the outbreak might be over, its effects will persist for many years. In the small nation with a population of just 7 million many lost relatives and friends to the disease. And its economy which
