Workers punching in for the graveyard shift may be better off not eating high-iron foods at night so they don’t disrupt the circadian clock in their livers. Disrupted circadian clocks, researchers believe, are the reason that shift workers experience higher incidences of type 2 diabetes, obesity and cancer.

Scientists have issued a statement saying they are skeptical about the effectiveness of so-called "brain game" products, which are marketed as helping older adults boost their mental powers. Signing the document were 69 scholars, including cognitive psychologists and neuroscientists from around the world.
A new study that may have implications for approaches to education finds that brain mechanisms, engaged when people allow their minds to rest and reflect on things they've learned before, may boost later learning.
Older individuals who are subliminally exposed to positive stereotypes about aging showed improved physical functioning that can last for several weeks. Researchers used a novel intervention method to examine for the first time whether exposure to positive age stereotypes could weaken negative age stereotypes and their effects over time, and lead to healthier outcomes.
As you glance over a menu or peruse the shelves in a supermarket, you may be thinking about how each food will taste and whether it’s nutritious, or you may be trying to decide what you’re in the mood for. A new neuroimaging study suggests that while you’re thinking all these things, an internal calorie counter of sorts is also evaluating each food based on its caloric density.
When the clocks “fall back” this year on Nov. 2, don’t let gaining an extra hour rob you of needed sleep. There’s plenty you can do now to establish healthy sleep habits and make it easier to reset your internal clock.
Improving household electricity access in India over the last 30 years contributed only marginally to the nation's total carbon emissions growth during that time, according to a new study.
The World Health Organization has admitted that it botched attempts to stop the now-spiraling Ebola outbreak in West Africa, blaming factors including incompetent staff and a lack of information. The UN health agency acknowledged that, at times, even its own bureaucracy was a problem.
Despite the growing popularity of using computer simulation to help teach college anatomy, students learn much better through the traditional use of human cadavers, according to new research that has implications for health care.
A study led by psychology researchers has found that people who play action video games such as Call of Duty or Assassin’s Creed seem to learn a new sensorimotor skill more quickly than non-gamers do.
Sugar-sweetened soda consumption might promote disease independently from its role in obesity, according to researchers who found in a new study that drinking sugary drinks was associated with cell aging.
Adolescents who saw printed signs explaining the number of miles they would need to walk to burn off the calories in a sugary drink were more likely to leave the store with a lower calorie beverage, a healthier beverage or a smaller size beverage. And those healthier choices persisted weeks after the signs came down.
Children who began life in overcrowded orphanages with bleak conditions and minimal human contact show that early childhood neglect is associated with changes in brain structure. New research has found that children who spent their early years in these institutions have thinner brain tissue in cortical areas that correspond to impulse control and attention.
An Ebola patient was left in an open area of an emergency room for hours, and nurses treating him worked without proper protective gear and faced constantly changing protocols, according to a statement released by the largest nurses' union. Among those nurses was Nina Pham, who now has Ebola. The CDC has said some breach of protocol probably sickened Pham, but the union says protocols were either non-existent or changing constantly.
From a review of the literature, it would appear that concerns in the scientific community and among the public regarding the potential adverse health effects of the increased consumption of energy drinks are broadly valid.
A clinical trial indicates that, for people with metabolic syndrome, a Mediterranean diet supplemented with extra-virgin olive oil or nuts may help reverse the condition.
Businesses and governments around the world are increasingly turning to voice biometrics, which sometimes are described as voiceprints, to replace passwords and fight fraud.
Defense officials say a report released today will lay out plans for the Pentagon to get a better handle on how climate change will affect the military, and determine how best to deal with the challenges.
Health conscious consumers are increasingly ditching old favorites vegetable and canola oil for trendy alternatives like coconut and peanut oil. But are they any healthier? And how do they compare with other options such as heated olive oil and butter?
A breach of infection control resulting in a Dallas health worker getting Ebola raises fresh questions about whether hospitals truly can safely take care of people with the deadly virus, as health officials insist is possible. Even in the U.S., with the best conditions and protective gear available, mistakes can happen that expose more people to Ebola, the new case reveals.
Exercise is one of the best ways to protect against dementia in later life and the earlier you start, the greater the effect, research suggests. Hobbies that keep the brain active, such as playing an instrument, going to concerts or joining a book club, can also be very helpful as long as it is an activity a person enjoys.
Fad diets come and go, but might there be something to the ones that involve consuming grapefruit and grapefruit juice? New research found that mice fed a high-fat diet gained 18 percent less weight when they drank clarified, no-pulp grapefruit juice compared with a control group of mice that drank water.
Google Chairman Eric Schmidt and other Silicon Valley executives say controversial government spying programs are undercutting the Internet economy and want Congress to step up stalled reform.
The global population is aging rapidly, which is why most countries encourage the elderly to lead active and healthy lifestyles. But, equating active aging strictly with health is too narrow a focus; the elderly can reap social and health benefits from activities that do not necessarily conform to official lifestyle recommendations– billiards for instance.
Researchers have identified epigenetic protein changes caused by binge drinking, a discovery that could lead to treatments for alcohol-related liver diseases such as cirrhosis and cancer.
Americans are living longer than ever before, according to a new report filled mostly with good news. U.S. life expectancy inched up again and death rates fell. Rates also dropped or held steady for nearly all the leading causes of death. However, the suicide rate reached its highest point in 25 years and the CDC isn’t sure why.
