Lead exposure in childhood linked to lower IQ, lower status jobs, as adults

A long-term study of more than 500 children who grew up in the era of leaded gasoline has shown that their exposure to the powerful neurotoxin may have led to a loss of intelligence and occupational standing by the time they reached age 38. The effects are slight, but significant, showing that the higher the

MicroRNA Treatment Restores Nerve Insulation, Limb Function in Mice with MS

Scientists partially re-insulated ravaged nerves in mouse models of multiple sclerosis (MS) and restored limb mobility by treating the animals with a small non-coding RNA called a microRNA. In a study published online March 27 in Developmental Cell, researchers at Cincinnati Children’s Hospital Medical Center report that treatment with a microRNA called miR-219 restarted production

Sleep Deprivation Impairs Ability to Interpret Facial Expressions

After a rough night's sleep, your ability to recognize whether those around you are happy or sad could suffer, according to a study led by a University of Arizona psychologist.

Vaccines: No Longer a Debate

In a 2015 presidential debate, moderator Jake Tapper asked GOP candidate hopefuls about their stances on vaccines. Among the candidates asked was Donald Trump, our newly inaugurated president, and to the dismay of many medical experts, he perpetuated a popular myth about a link between autism and vaccines. Where science has weighed in and reached

Critical step in DNA repair, cellular aging pinpointed

DNA repair is essential for cell vitality, cell survival and cancer prevention, yet cells’ ability to patch up damaged DNA declines with age for reasons not fully understood. Now, research led by scientists at Harvard Medical School reveals a critical step in a molecular chain of events that allows cells to mend their broken DNA.

Daily consumption of tea may protect the elderly from cognitive decline, study suggests

Assistant Professor Feng Lei from NUS Yong Loo Lin School of Medicine led a research team which found that regular consumption of tea reduces elderly persons’ risk of cognitive decline by 50 per cent, and potentially up to 86 per cent for persons genetically at risk of Alzheimer’s. The study was published in The Journal

No opioids, please: A growing movement lets patients refuse prescriptions

The ease of relapsing into opioid addiction has led a growing number of states to help residents make it clear to medical professionals they do not want to be prescribed the powerful painkillers. Connecticut and Alaska are two of the latest considering legislation this year that would create a “non-opioid directive” patients can put in

‘Huge advance’ in fighting world’s biggest killer disease

An innovative new drug can prevent heart attacks and strokes by cutting bad cholesterol to unprecedented levels, say doctors. The results of the large international trial on 27,000 patients means the drug could soon be used by millions. The British Heart Foundation said the findings were a significant advance in fighting the biggest killer in

WHO: Pollution, Environment Taking Toll of 1.7 Million Child Deaths Per Year

Pollution and environmental hazards like dirty water continue to amass a staggering yearly death toll, mostly in the developing world, according to a new analysis by the World Health Organization. Some 1.7 million children under the age of 5 died from preventable causes, according to two new reports, made up of multiple data sets and

New ‘gene silencer’ drug injections reduce cholesterol by 50% in clinical trial

The first in a new class of gene-silencing drugs, known as inclisiran, has halved cholesterol levels in patients at risk of cardiovascular disease. The findings come from the largest trial yet to test the safety and effectiveness of this kind of therapy. The technique, known as RNA interference (RNAi) therapy, essentially ‘switches off’ one of

Healthiest Hearts in Amazon Tribe

Study estimates that an 80 year old from the Tsimane (pronounced chee-MAH-nay) group had the same vascular age as an American in their mid-fifties. The Tsimane people - a forager-horticulturalist population of the Bolivian Amazon - have the lowest reported levels of vascular ageing for any population, with coronary atherosclerosis (hardening of the arteries) being

Brain imaging can determine whether you know you acted criminally

Judges and juries always ponder whether people act “knowingly” or “recklessly” during criminal activity — and neuroscience has had little to add to the conversation. But now, researchers, including computational neuroscientist Read Montague of the Virginia Tech Carilion Research Institute, have discovered that brain imaging can determine whether someone is acting in a state of

Volunteers are in better health than non-volunteers

Even after controlling for other determinants of health (gender, age, education level, migrant status, religiosity and country of origin), volunteers are substantially in better health than non-volunteers. Doctoral researcher Jens Detollenaere: “This association is comparable in size to the health gains of being a man, being five years younger or being a native (compared to

Flame retardant chemicals may affect social behavior in young children

Some chemicals added to furniture, electronics and numerous other goods to prevent fires may have unintended developmental consequences for young children, according to a pilot study released today. Researchers from Oregon State University found a significant relationship between social behaviors among children and their exposure to widely used flame retardants, said Molly Kile, an environmental

Two-thirds of Americans see docs who got paid by drug companies

About 65 percent of those surveyed as a part of the study by Genevieve Pham-Kanter, PhD, an assistant professor in Drexel’s Dornsife School of Public Health, visited a doctor within the last year who had received payments or gifts from pharmaceutical or medical device companies. What’s more: Only 5 percent of those surveyed knew that

Flour, Oil and Bouillon Cubes, Improving Health Worldwide

Most Americans take fortification—the addition of micronutrients to our food—for granted. Our milk has added vitamin A and vitamin D. Our salt has iodine. Breakfast cereal is fortified with iron. Each one of these additives was put in place to address the diseases caused by nutritional deficiencies: Not enough vitamin A can cause blindness. Not

Brake dust may cause more problems than blackened wheel covers

Metals from brakes and other automotive systems are emitted into the air as fine particles, lingering over busy roadways. Now, researchers at Georgia Institute of Technology have shown how that cloud of tiny metal particles could wreak havoc on respiratory health. In a study published January 31 in the journal Environmental Science & Technology, the

How molecular machines may drive the future of disease detection and drug delivery

University of Alberta scientists have pulled into the lead in a race to use nanomachines for improved disease detection and drug delivery in patients. In a study published in Nature Communications, the researchers describe the creation of synthetic DNA motors in living cells. The process - previously only successful in test tubes - demonstrates how

Why the cloud could hold the cure to diseases

We constantly hear about programs such as Race for the Cure, Breast Cancer Awareness Month, The Ice Bucket Challenge, and other fundraising or awareness initiatives for diseases.  However, hearing a disease has been cured almost never happens. With billions of dollars being used to research diseases around the world, many people started looking for reasons
