Neurochemical changes in the brain differ among patients with social anxiety treated using both SSRIs and CBT, compared to those treated using only CBT. While the combined treatment involving the medicine blocked the serotonin transporters, availability of such transporters increased in patients who only received CBT.

Treatment using selective serotonin reuptake inhibitors, or SSRIs, is effective for depression and anxiety and can be even more effective when combined with cognitive behavioral therapy, or CBT. However, it has not been established which mechanisms in the brain clarify the clinical improvement.

In a double-blind positron emission tomography (PET) study, researchers at Uppsala University investigated people with social anxiety and looked at how serotonin and dopamin...

Drexel Materials science researchers demonstrate MXene polymer coating can block and absorb interference. A recent discovery by materials science researchers in Drexel University’s College of Engineering might one day prevent electronic devices and components from going haywire when they’re too close to one another. A special coating that they developed, using a type of two-dimensional material called MXene, has shown to be capable of absorbing and disbursing the electromagnetic fields that are the source of the problem.

Buzzing, feedback or static are the noticeable manifestation...

A newly discovered type of transferrable DNA structure with a sci-fi name appears to play a role in balancing atmospheric methane. In Star Trek, the Borg are a ruthless, hive-minded collective that assimilate other beings with the intent of taking over the galaxy. Here on nonfictional planet Earth, Borgs are DNA packages that could help humans fight climate change.

Last year, a team led by Jill Banfield discovered DNA structures within a methane-consuming microbe called Methanoperedens that appear to supercharge the organism’s metabolic rate. They named the genetic elements “Borgs” because the DNA within them contains genes assimilated from many organisms...

Distinguishing this intrigung material behavior at small scales could reduce energy demands for computing. As electronic devices become smaller and smaller, the materials that power them need to become thinner and thinner. Because of this, one of the key challenges scientists face in developing next-generation energy-efficient electronics is discovering materials that can maintain special electronic properties at an ultrathin size.

Advanced materials known as ferroelectrics present a promising solution to help lower the power consumed by the ultrasmall electronic devices found in cellphones and computers...
