A new study found that certain brain injuries, such as damage to the amygdala and ventromedial prefrontal cortex, may reduce the likelihood of developing post-traumatic stress disorder (PTSD) in combat-exposed veterans. The findings suggest that drugs or pacemaker-like devices targeting these areas might be effective treatments for PTSD.
Bone skates were an early means of human-powered transport, with a recent study supporting their origins in Southern Finland. The use of bone skates limited energy consumption by 10% in winter, but only slightly in other North European countries.
Research at Rockefeller University reveals that flies use stereo cues to navigate towards scented targets more accurately when detecting smells with both olfactory organs. By exploiting infrared technology, scientists created an environment where they could visualize and quantify the distribution of smells.
Researchers have developed gold nanoparticles with antibody fragments that can identify tumors in living animals. The particles emit a specific signal when illuminated by a laser beam, enabling early detection of cancer. This technology offers a non-invasive and potentially more effective approach to cancer diagnosis.
Researchers find that adenosine, a sleep-inducing brain chemical, plays a central role in deep brain stimulation's success. The technique disrupts abnormal nerve signals and alleviates symptoms in patients with Parkinson's disease and other brain disorders.
