The experimental drugs target brain cells’ ability to respond to the chemical messenger glutamate, however, it has been unclear how they work. The recent discovery of a molecular amplification system helps explain how the drugs achieve an antidepressant effect by altering signaling in particular neurons.
Instead of being harvested, many cover crops are returned to the soil. In this way their nutrients can be used by other crops. Legume cover crops, in particular, are an excellent source of nitrogen — a key nutrient for all plant life. Researchers find cover crop decomposition and nitrogen release vary with type of cover […]
Almost half of patients with advanced lung cancer receive more than the recommended number of radiation treatments to reduce their pain, according to a new study. Radiation therapy that is palliative, or not intended to cure, can reduce the pain from lung tumors and improve quality of life. But unnecessary treatments add to costs and […]
A new report documents all of the fishes that live in the Salish Sea. In total, 253 fish species have been recorded, and that’s about 14 percent more than in the last count.
The Latino culture, more than others, places a high value on the family unit; yet, little research has examined the dynamics of Latino family relationships and how those dynamics affect children’s development. Now, a researcher has found sibling relationship quality in adolescence affects Mexican-origin adolescents’ and young adults’ later depressive symptoms and their involvement in […]
Scientists have made a remarkable breakthrough in the field of fluorescence enhancement via a discovery they believe could drive the next advances in sensor technology, energy saving and harvesting, lasers and optoelectronics.
Chemists have developed novel porous materials called ‘covalent organic frameworks,’ which provide a basis for the design of polymeric photocatalysts with tunable physical, chemical and electronic properties.
Adult smokers with a history of problem drinking who continue smoking are at a greater risk of relapsing three years later compared with adults who do not smoke. While treatments for alcohol abuse traditionally require concurrent treatment for problems around illicit substance use, smoking has not generally been part of alcohol or substance use treatment.
In a series of experiments, researchers show that novel communication systems reflect a variety of environmental and interactional factors. These findings challenge long-established ideas that syntax is innate and strongly determined by cognitive biases.
In an effort to help develop a domestic supply of rare earth elements, researchers at Worcester Polytechnic Institute have developed a novel method of chemically separating these materials — specifically neodymium, dysprosium, and praseodymium — from the drive units and motors of discarded electric and hybrid cars. The goal is to recycle rare earths that […]
