Speedy cockroaches help researchers train robots to walk

Science
Dec. 8 (UPI) -- Scientists have identified a shift in the gaits of speedy cockroaches as the insects kick it into high gear. The discovery could help engineers train robots to walk more stably and efficiently.The latest research -- published this week in the journal Frontiers in Zoology -- shows a mid-speed change in the biomechanics of a cockroach's gait characterizes its acceleration from scurry to sprint. The shift recalls those made by other animals, including horses, which famously transition from a trot to a gallop."I was particularly surprised that a change in mechanisms stabilizing the animal's movement goes hand in hand with a change in leg coordination," Tom Weihmann, a zoologist at the University of Cologne in Germany, said in a news release.When crawling at a slow pace, a cockr...
Simple evaluation could help choose therapy or medication for anxiety treatment

Simple evaluation could help choose therapy or medication for anxiety treatment

Science
Dec. 7 (UPI) -- A short, simple evaluation can help doctors determine whether a patient with anxiety will respond best to medication or talk therapy, according to new research.Researchers at the University of Illinois at Chicago found that by measuring a patient's error-related negativity, or ERN, they can determine whether or not a patient is an ideal candidate for cognitive behavioral therapy.CBT works by altering a participant's negative or problematic thoughts and behaviors. Psychiatrists and psychologists using CBT teach patients new cognitive and behavioral techniques to better manage anxiety and related symptoms.Both CBT and selective serotonin reuptake inhibitors, or SSRIs, the most common type of anxiety drug, have good track records in treating generalized anxiety. Therapy can so...

How Eating Breakfast Can Help Your Metabolism

Health
The findings suggest that eating breakfast every morning may help lower people’s risk for type 2 diabetes and cardiovascular disease. This article originally appeared on Time.com.Plenty of research has found that eating breakfast is important for weight maintenance, metabolism and overall good health. Now, the evidence gets even stronger: a small new randomized controlled trial finds that regularly eating a substantial morning meal directly affects how fat cells function in the body by changing the activity of genes involved in fat metabolism and insulin resistance. The findings suggest that eating breakfast every morning may help lower people’s risk for type 2 diabetes and cardiovascular disease, the study authors say—and that even if a morning meal increases a
Digital pills can help doctors monitor opioid abuse

Digital pills can help doctors monitor opioid abuse

Health
Nov. 20 (UPI) -- Researchers at Brigham and Women's Hospital are testing the use of ingestible sensors to track opioid ingestion patterns.The sensor is planted in a gelatin capsule along with the medication. The digital pills can help doctors track how frequently patients are using their opioid prescription, and potentially alert healthcare officials to signs of abuse.During initial tests, researchers found opioid-naive patients actually took fewer pills over a shorter period of time while managing fracture pain.Researchers published the results of their tests in the journal Anesthesia & Analgesia."As an investigational tool, the digital pill provides a direct measure of opioid ingestion and changes in medication-taking behavior," lead study author Dr. Edward Boyer said in a news relea...

Deep fat fryers may help form cooling clouds

Media playback is unsupported on your deviceFatty acids released into the air from cooking may contribute to the formation of clouds that cool the climate, say scientists.Fatty acid molecules comprise about 10% of fine particulates over London, and such particles help seed clouds.But researchers dismiss the idea that cooking fats could be used as a geo-engineering tool to reduce warming.Instead, the research is designed to help reduce uncertainties about the role of cooking fats on climate.Researchers believe the fatty molecules arrange themselves into complex 3-D structures in atmospheric droplets.These aerosols persist for longer than normal and can seed the formation of clouds which experts say can have a cooling effect on the climate.The authors say the study will shed new light on the...
