For children, stress can go a long way. A little bit provides a platform for learning, adapting and coping. But a lot of it — chronic, toxic stress like poverty, neglect and physical abuse — can have lasting negative impacts. A team of researchers recently showed these kinds of stressors, experienced in early life, might be changing the parts of developing children's brains responsible for learning, memory and the processing of stress and emotion.

New research has provided a major new theory on the cause of the ice age that covered large parts of the Northern Hemisphere 2.6 million years ago.

Ground-breaking experiments have been conduced to uncover the links between language and emotions. Researchers were able to demonstrate that the articulation of vowels systematically influences our feelings and vice versa. The authors concluded that it would seem that language users learn that the articulation of 'i' sounds is associated with positive feelings and thus make use of corresponding words to describe positive circumstances. The opposite applies to the use of 'o' sounds.

Researchers have found strong evidence that attaining a higher level of education and spending more years in school are two factors associated with a greater prevalence and severity of nearsightedness, or myopia. The research is the first population-based study to demonstrate that environmental factors may outweigh genetics in the development of myopia.

Surrounding the sun is a vast atmosphere of solar particles, through which magnetic fields swarm, solar flares erupt, and gigantic columns of material rise, fall and jostle each other around. Now, using NASA's Solar Terrestrial Relations Observatory, scientists have found that this atmosphere, called the corona, is even larger than thought, extending out some 5 million miles above the sun's surface -- the equivalent of 12 solar radii.

A majority of Americans are overweight or obese, a factor in the rapid rise in common diseases like diabetes, heart disease, cancer, high blood pressure and more. According to research, energy balance is a viable public health solution to address the obesity epidemic. A new paper outlines steps to incorporate energy balance principles into public health outreach in the U.S.

You may want to rethink cheering up your friends who have low self-esteem because chances are they don't want to hear it. People with low self-esteem have overly negative views of themselves, and often interpret critical feedback, romantic rejections, or unsuccessful job applications as evidence of their general unworthiness. A new study found that they likely don't want you to try to boost their spirits.

A fundamental mechanism by which the brain maintains its internal balance has been discovered by researchers. The mechanism involves the brain's most basic inner wiring and the processes that control whether a neuron relays information to other neurons or suppresses the transmission of information.
