Glasses could help people with visual impairments navigate the world around them. Extended ...

A five-year, $2 million grant to study the pharmacological effects of the areca nut, commonly known as the betel nut, was awarded to a UTHealth Houston researcher by the National Institute on Drug Abuse, part of the National Institutes of Health (NIH). The study, led by Alan Myers, PharmD, PhD, associate professor of pharmacology with UTHealth Houston School of Dentistry, will investigate how chemicals in the areca nut are metabolized in the body’s organs, particularly in the liver, and how that process is disrupted by alcohol or menthol. “On the global level, areca nut chewing has been around since antiquity, but still poses a major public health ...

Optimal windows exist for action and perception during the 0.8 seconds of a heartbeat, according to research published November 28th in the open access journal PLOS Biology. The sequence of contraction and relaxation is linked to changes in the motor system and its ability to respond to stimulation, and this could have implications for treatments for depression and stroke that excite nerve cells. The ways in which we perceive and engage with the world are influenced by internal bodily processes such as heartbeats, respiration and digestion. Cardiac activity can influence auditory and ...

A new catalog produced by a French-led international team of astronomers shows that NASA’s Fermi Gamma-ray Space Telescope has discovered 294 gamma-ray-emitting pulsars, while another 34 suspects await confirmation. This is 27 times the number known before the mission launched in 2008. “Pulsars touch on a wide range of astrophysics research, from cosmic rays and stellar evolution to the search for gravitational waves and dark matter,” said study coordinator David Smith, research director at the Bordeaux Astrophysics Laboratory in Gironde, France, which is part of CNRS (the ...

FINDINGS Researchers at the UCLA Jonsson Comprehensive Cancer Center have found certain immune cells can still fight cancer even when the cancer cells lack an important protein that the immune system relies on to help track down cancer cells. The team discovered the absence of the crucial protein B2M seems to activate an alternative immune response involving natural killer (NK) cells and CD4+ T cells in both animal studies and patient tumor biopsies, indicating a potential backup mechanism in the immune system to recognize and attack cancer cells. BACKGROUND Immunotherapies, such as immune ...

AMES, Iowa – A research poster dated Dec. 9, 2015, hangs just outside Nicole Hashemi’s Iowa State University laboratory. It introduces a major project for Hashemi and her research group. And it’s evidence that scientific persistence sometimes equals scientific advancement.   Hashemi, an associate professor of mechanical engineering, and her students have been working all these years to develop a “placenta-on-a-chip.” In this case that’s a thin, rectangular, clear, polymer block with two tiny microchannels – just millionths of ...

A longstanding hypothesis in neurobiology was that a single neuron releases a single type of neurotransmitter, a molecule used by neurons to communicate with one another. In recent decades, several neurons have been found to release more than one neurotransmitter. This phenomenon called co-transmission is increasingly gaining recognition as a powerful and versatile molecular mechanism useful for the dynamic regulation of diverse neural circuits. However, precisely how co-transmission affects the firing of ...

Across the entire animal kingdom, visual images are processed by two major neuronal pathways that extract light and dark stimuli from visual scenes – ON (light on) and OFF (light off) pathways. Light stimuli are brighter than their background like a white cloud in a gray sky whereas dark stimuli are darker than the background like a black bird in a blue sky. The two pathways can extract stimuli with different contrasts but some pathways are more sensitive than others. In carnivores and rodents, ON pathways are more sensitive ...

Air quality in the Dallas-Fort Worth metropolitan area continues to miss safety levels set by the Environmental Protection Agency (EPA) and is unlikely to meet EPA goals anytime soon, according to new research from The University of Texas at Arlington. Purnendu “Sandy” Dasgupta, professor of chemistry and biochemistry and the Hamish Small Chair of Ion Analysis at The University of Texas at Arlington, said the region’s low population density, lack of widespread public transportation and reliance on cars contribute to its poor air quality. Its ozone values have exceeded safety levels set by the EPA for the last 20 years. “Compared ...

With more than 400 million privately owned firearms in circulation across the United States, gun violence prevention efforts have emphasized secure firearm storage as a method for preventing injury and death. But some owners may not see the value in doing so, according to Rutgers researchers. Despite evidence that secure storage can effectively reduce the risk of suicide and unintentional shootings, many firearm owners typically keep at least one firearm stored loaded and unlocked, quickly accessible in case of home invasion. ...

LOS ANGELES (November 28, 2023)—Thousands of adolescents and young adults have outpatient surgery every day and are sent home with pain medication. Although the need for medication is clear, the best way to treat the pain is not. A new study led by investigators at the University of Michigan and Children’s Hospital Los Angeles will compare two treatment regimens—one that uses a regimen of non-opioid medication and another that adds a low-dose opioid—to determine the safest and most effective way to treat pain in adolescents and young adults recovering from common outpatient surgeries. In the past, opioids ...

The slash-and-burn agriculture practiced by many Indigenous societies across the world can actually have a positive impact on forests, according to a new study done in Belize.   Researchers found that in areas of the rainforest in which Indigenous farmers using slash-and-burn techniques created intermediate-sized farm patches – neither too small nor too large – there were increases in forest plant diversity.   This contradicts what had long been the standard view in the past, promoted by the ...
