Sleep is known to allow animals to re-energize themselves and consolidate memories. Rapid eye movement (REM) sleep is known to play an important role in maintaining a healthy mental and physical life, but the molecular mechanisms behind this state are barely understood. Now, scientists have identified a pair of genes that regulate how much REM and non-REM sleep an animal experiences.
Scientists have a new way to fight peripheral artery disease, or PAD, an ailment affecting 8 million Americans.
A research team has published a study that improves the understanding of the pain-sensing neurons that respond to tissue injury during surgery.
New research proves writing letters of gratitude, like Jimmy Fallon's 'Thank You Notes,' is a pro-social experience people should commit to more often. The gesture improves well-being for not only letter writers but recipients as well.
A team of researchers has, for the first time, fully 3D printed an array of light receptors on a hemispherical surface. This discovery marks a significant step toward creating a 'bionic eye' that could someday help blind people see or sighted people see better.
Clinicians should consider how the way we think can make us vulnerable to obesity, and how obesity is genetically intertwined with brain structure and mental performance, according to new research.
In a finding that caps years of exploration into the tiny particle known as the Higgs boson, researchers have traced the fifth and most prominent way that the particle decays into other particles. The discovery gives researchers a new pathway by which to study the physical laws that govern the universe.
Researchers are discovering how forest conservation in Fiji can minimize the impact of human activities on coral reefs and their fish populations.
During their annual migration to wintering sites in Mexico, monarch butterflies encounter dangers ranging from cars and trucks to storms, droughts and predators. A study has found evidence that these iconic insects might be facing a new challenge.
New research shows that the ability to understand what someone is feeling based on their tone of voice can be challenging in mid-adolescence (between 13-15 year olds), particularly when it comes to tones of voice which express anger, meanness, disgust, or happiness.
