New research links iron levels in the brain with diet, though the effects seem to differ for men and women.
Getting the recommended 150 minutes of moderate exercise each week may be challenging for some older adults, but researchers say that doesn’t mean they shouldn’t work at it.
Twitter is a marijuana-friendly place, according to a new analysis of every pot-related tweet sent during a one-month period in early 2014.
A study with mice shows how the mammalian brain is able to maintain a constant state of up and down—while under anesthesia, during slow-wave sleep, or even amid calm wakefulness.
It makes sense that we have strong memories from events that carry a lot of emotion—for example, 9/11 or the birth of a child.
Scientists have experimentally observed for the first time a phenomenon in ultracold, three-atom molecules predicted by Russian theoretical physicist Vitaly Efimov in 1970.
Indigenous people govern about half of all remaining undeveloped land on the planet. New research with indigenous people in the Amazon suggests they may outperform satellites in measuring the true carbon storage potential of the rainforest.
Astronomers have identified for the first time a “changing look” quasar, a gleaming object in deep space that appears to have its own on-off switch.
Not all postpartum depression is the same. Researchers say there are three distinct subtypes based on symptoms, and it’s important for doctors to identify the specific type to tailor treatment.
The benefits of eating fish may do more than just offset the risks of mercury exposure to unborn babies.
A survey of unmarried, childless men and women between the ages of 18 and 32 in the United States shows most want to split responsibilities equally.
Fragile X syndrome may not only be a problem of receivers in the brain letting in too much information.
In an effort to understand autism spectrum disorder (ASD), researchers have zeroed in on synchronization between different parts of the brain.
Instead of killing tumor cells outright, doctors are exploring a new anti-cancer strategy that subtly hardens the cells so they can’t invade new areas of the body.
A new study shows that your personality in your 20s can predict your lifespan. In addition, your close friends can probably recognize the relevant personality traits better than you can.
Hydrogels can work like scaffold upon which cells can build tissue. Researchers have created a new version of a hydrogel that can be injected into an internal wound.
College freshmen who spend a lot of time on social media risk having a lower GPA, but the problem isn’t Facebook.
As glacial ice melts, sea levels are likely to rise around the globe. How fast this will happen is uncertain, however. In the case of the Greenland Ice Sheet, the more temperatures increase, the faster the ice will melt, according to computer model experiments.
Newly-discovered ankle bone fossils smaller than a penny show that our earliest primate ancestors most likely lived in trees.
It’s been long known that human survival depends a bit on something called “fight or flight.” How this alarm in our brain first goes off, and what other parts of the brain are mobilized to express fear—and remember to avoid danger in the future—have been less clear.
