Researchers have designed a device that delivers two medications that help stop HIV transmission.
The fast-food industry spent $5 billion on advertising in 2019, and the advertisements disproportionately targeted Black and Hispanic youth, according to new research published today by the Rudd Center for Food Policy and Obesity at the University of Connecticut. The new report, Fast Food FACTS 2021, finds that the industry's annual ad spending in 2019 increased by over $400 million since 2012, and that children and teens were viewing on average more than two fast food TV ads per day.
Researchers at the National Eye Institute (NEI) have determined how certain short protein fragments, called peptides, can protect neuronal cells found in the light-sensing retina layer at the back of the eye. The peptides might someday be used to treat degenerative retinal diseases, such as age-related macular degeneration (AMD).
Michigan State University entomologists Sarah Smith and Anthony Cognato have discovered more than three dozen species of ambrosia beetles -- beetles that eat ambrosia fungus -- previously unknown to science.
New study results indicate that different comorbid conditions affecting individuals diagnosed with COVID-19 may impact how long they continue to receive positive SARS-CoV-2 polymerase chain reaction (PCR) test results.
An alternate-day intermittent fasting schedule offered less fat-reducing benefits than a matched "traditional" diet that restricts daily energy intake, according to a new, 3-week randomized trial involving 36 participants.
A new study looking at the way human cells activate the immune system in response to SARS-CoV-2 infection could open the door to even more effective and powerful vaccines against the coronavirus and its rapidly emerging variants.
A new approach to studying conjugated polymers made it possible for an Army-funded research team to measure, for the first time, the individual molecules' mechanical and kinetic properties during polymerization reaction. The insights gained could lead to more flexible and robust soft electronic materials, such as health monitors and soft robotics.
Scientists today track electrical signals and voltage changes in neurons and muscle cells by labeling individual cells or probing with electrodes. UC Berkeley and Stanford scientists have developed a new type of sensor that employs a sheet of graphene to get a continuous measure of electric field in these tissues. Electric fields change graphene's reflectance. The physicists found a way to amplify and measure the changes caused by action potentials in a beating embryonic chicken heart.
Spectacular images of a molecule that shuttles omega-3 fatty acids into the brain may open a doorway for delivering neurological therapeutics to the brain.
