Researchers have discovered that individual neurons in the brain can be compared to tiny computers that analyze and integrate information from different sources. These findings have implications for improving hearing aids, sonar devices, and speech recognition systems.
Researchers at Sandia National Laboratories have created microtransmissions, which can augment the power of tiny microengines by a significant margin. The new device increases power output by a factor of 3 million, generating enough force to move a one-pound object.
Researchers determined the structure of methyl-coenzyme M reductase, a key enzyme in methanogenesis that produces methane for cellular energy. The crystal structure has provided new insights into the enzymatic mechanism and will aid in characterizing other enzyme states.
Researchers discovered muscle dysmorphia, a disorder causing individuals to obsess over their bodies, leading to detrimental habits like steroid abuse. The study emphasizes the importance of public health implications as weightlifting gains popularity.
The USMP-4 experiment has provided new data on metallic dendrite growth, revealing a closer correspondence between microgravity and theory. The findings are being used to improve computer casting models, reducing the design process from weeks to days.
Dystonia results from a deficiency in dopamine receptors, according to researchers at Washington University School of Medicine. A study found that dopamine levels were 97-98% lower on the treated side of the brain during dystonic symptoms.
A study of 1,399 Vietnam veterans found that those with post-traumatic stress disorder (PTSD) were 50-150% more likely to develop serious diseases. Veterans with PTSD who saw heavy combat were particularly at risk for circulatory and respiratory problems.
Researchers Andrea Cooper and Julie Inamine are investigating why Mycobacterium avium causes disease in AIDS patients despite humans not being natural hosts. The studies aim to identify genes responsible for the bacteria's virulence and develop drugs to prevent disease.
Scientists use sensors to measure the intensity of vibrations at different frequencies, optimizing experiments for the US Microgravity Payload. By analyzing data from past missions, they can plan future ones more effectively and minimize disturbances.
Research by Matthew Hardy and colleagues found that stress hormones overpower the enzymes responsible for producing testosterone in testes, leading to a suppression of sperm formation. The study provides insight into male reproduction and may aid the design of new male contraceptives.
Researchers discover that dopamine levels can enhance or impair working memory, with a low dose of the drug bromocriptine improving scores in low-capacity subjects but worsening performance in high-capacity individuals. The study suggests an optimal level of dopamine for short-term memory to function properly.
IntraLase Corporation will develop ultrafast ophthalmic lasers for refractive and other surgical procedures, enhancing eye care with precise technology. The company combines U-M intellectual property with Escalon Medical's patents to bring innovative laser solutions to the medical field.
