Virus-mimicking drugs may overcome immunotherapy resistance in tumors

Researchers at the UCLA Jonsson Comprehensive Cancer Center have found that a drug that activates the body's natural defenses by behaving like a virus may also make certain stealthy melanoma tumors visible to the immune system, allowing them to be better targeted by immunotherapy.

Cover crop could be a promising part of integrated weed management for edamame

For vegetable growers, weeds can mean lost income from reduced yield and foreign plant matter contaminating the harvest. But for many crops, particularly vegetable legumes, weed management options are very limited.

Study clarifies role of ERβ in growth and regeneration of skeletal muscle in female mice

Researchers at Kumamoto University, Japan generated mice lacking the estrogen receptor beta (ERβ) gene, both fiber-specific and muscle stem cell-specific, which resulted in abnormalities in the growth and regeneration of skeletal muscle in female mice.

Dopamine and serotonin found to be involved in perception, cognitive capacities

In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals -- dopamine and serotonin -- are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.

Researchers trace neurons in mosquitoes that sense blood's distinctive flavor

It's one of the world's deadliest animals, and it has a taste for human blood: the mosquito. Mosquitoes spread diseases like malaria, dengue, and yellow fever that kill at least a half a million people each year. Now researchers are learning what humans taste like to mosquitoes, down to the individual neurons that sense blood's distinctive, delectable flavor.

UMD researchers use AI tools to predict how and when proteins form different shapes

By applying natural language processing tools to the movements of protein molecules, University of Maryland scientists created an abstract language that describes the multiple shapes a protein molecule can take and how and when it transitions from one shape to another.

Biofilms of major pathogenic bacteria can deform soft surfaces

The vast majority of bacteria in the world live on surfaces by forming structures called "biofilms". These communities host thousands to millions of bacteria of different types, and are so biologically complex and active that scientists describe them as "cities".
