Artificial Intelligence Used to Limit Collision-Prone Roadways

Kennesaw State University and the Georgia Department of Transportation (GDOT) are nearing completion on a two-year study to develop an image-based system for monitoring and assessing the safety of intersections that could potentially prevent fatal crashes.

‘Hide or Get Eaten,’ Urine Chemicals Tell Mud Crabs

Mud crabs hide for their lives if blue crabs, which prey upon them, pee anywhere near them. Pinpointing urine compounds for the first time that warn the mud crabs of predatory peril initiates a new level of understanding of how chemicals invisibly regulate undersea wildlife and ecosystems.

Want to Beat Antibiotic-Resistant Superbugs? Rethink That Strep Throat Remedy

Antibiotics could become nearly useless by mid-century against intense infections due to bacteria evolving antibiotic resistance. And alternatives haven't been able to replace them. It's time for a rethink: Try reducing antibiotic use for small infections and find alternate treatments for them. Save antibiotics for the big infections.

Lactic acid bacteria, commonly used as probiotics to improve digestive health, can offer protection against different subtypes of influenza A virus, resulting in reduced weight loss after virus infection and lower amounts of virus replication in the lungs, according to a study led by Georgia State University.

Nanotexturing Creates Bacteria-Killing Spikes on Stainless Steel Surfaces

stainless-steel007.jpg

By using an electrochemical etching process on a common stainless steel alloy, researchers have created a nanotextured surface that kills bacteria while not harming mammalian cells. If additional research supports early test results, the process might be used to attack microbial contamination on implantable medical devices and on food processing equipment made with the metal.

Perking Up and Crimping the ‘Bristles’ of Polyelectrolyte Brushes

PEbrushes.jpeg

A molecular-sized brush that looks like a shoe brush has properties with great potential for the materials industry and medicine, but polyelectrolyte brushes can be sensitive, and getting them to work right tricky. New research shows what can make them break down, but also what can get them to systematically recover.

The Force Is Strong: Amputee Controls Individual Prosthetic Fingers

Luke Skywalker’s bionic hand is a step closer to reality for amputees in this galaxy. Researchers at the Georgia Institute of Technology 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.
