Visualizing single molecules in whole cells with a new spin

Tue, 12/12/2017 - 9:54am
Scientists have adapted DNA-PAINT technology to microscopes that are widespread among cell biology laboratories, called confocal microscopes, and that are used by researchers to image whole cells and thicker tissues at lower resolution. They have demonstrated that the method can visualize a variety of different molecules, including combinations of different proteins, RNAs and DNA throughout the entire depth of whole cells at super-resolution.

Action games expand the brain's cognitive abilities, study suggests

Tue, 12/12/2017 - 7:21am
The human brain learns and adapts. Numerous research studies have focused on the impact of action video games on the brain by measuring cognitive abilities, such as perception and reaction time. An international team of psychologists has assembled data from the last fifteen years to quantify how action video games impact cognition. The research has resulted in two meta-analyses, which reveal a significant improvement in the cognitive abilities of gamers.

Computer scientists develop a simple tool to tell if websites suffered a data breach

Tue, 12/12/2017 - 7:20am
Computer scientists have built and successfully tested a tool designed to detect when websites are hacked by monitoring the activity of email accounts associated with them. The researchers were surprised to find that almost 1 percent of the websites they tested had suffered a data breach during their 18-month study period, regardless of how big the companies' reach and audience are.

How errors affect credibility of online reviews

Mon, 12/11/2017 - 4:27pm
Shoppers increasingly consult online reviews before making holiday purchases. But how do they decide which reviewers to trust? Consumer trust in online reviews is influenced by spelling errors and typos, research shows. But how much those errors influence each consumer depends on the type of error and that consumer's general tendency to trust others.

The force is strong: Amputee controls individual prosthetic fingers

Mon, 12/11/2017 - 12:16pm
Luke Skywalker's bionic hand is a step closer to reality for amputees in this galaxy. Researchers have created an ultrasonic sensor that allows amputees to control each of their prosthetic fingers individually. It provides fine motor hand gestures that aren't possible with current commercially available devices.

Revolutionizing electronics using Kirigami

Fri, 12/08/2017 - 12:23pm
A research team has developed an ultrastretchable bioprobe using a 'Kirigami' designs. The Kirigami-based bioprobe enables one to follow the shape of spherical and large deformable biological samples such as heart and brain tissues. In addition, its low strain-force characteristic reduces the force induced on organs, thereby enabling minimally invasive biological signal recording.
