- Don't be a stranger -- study finds rekindling old friendships as scary as making new onesPsychologists have found that people are as hesitant to reach out to an old friend as they are to strike up a conversation with a stranger, even when they had the capacity and desire to do so.
- Infected: Understanding the spread of behaviorA team of researchers found that long-tie connections accelerate the speed of social contagion.
- Researchers create artificial cells that act like living cellsResearchers describe the steps they took to manipulate DNA and proteins -- essential building blocks of life -- to create cells that look and act like cells from the body. This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems and diagnostic tools.
- Innovative microscopy demystifies metabolism of Alzheimer'sUsing state-of-the-art microscopy techniques, researchers have shed new light on the underlying mechanisms driving Alzheimer's disease.
- Odor-causing bacteria in armpits targeted using bacteriophage-derived lysinA research team has synthesized a lysin that during in vitro experiments targets bacteria responsible for producing odors in human armpits.
- Gentle defibrillation for the heartUsing light pulses as a model for electrical defibrillation, scientists developed a method to assess and modulate the heart function. The research team has thus paved the way for an efficient and direct treatment for cardiac arrhythmias. This may be an alternative for the strong and painful electrical shocks currently used.
- Dengue fever infections have negative impacts on infant health for three yearsDengue infections in pregnant women may have a negative impact on the first years of children's lives, new research has found.
- Exploring brain synchronization patterns during social interactionsSocial interactions synchronize brain activity within individuals and between individuals. In a new study, researchers compared brain synchronization between pairs of people with relatively strong social ties (acquaintance pairs) and pairs with almost no social ties (stranger pairs). The study found that during a cooperative task, the stranger pairs exhibited more closely connected brain networks […]
- Bella moths use poison to attract mates: Scientists are closer to finding out howResearchers sequence the bella moth genome, which they used to pinpoint specific genes that may confer immunity to noxious alkaloids.
- Eye-opener: Pupils enlarge when people focus on tasksNormally, a person's pupils naturally widen (or dilate) in low-light environments to allow more light into the eye. However, in a new study, researchers reported that a person's pupils also dilate when they are concentrating on tasks. In particular, they found that the more a person's eyes dilated during the task, the better they did […]
