Q&A: Colorado's Latina legislators giving voice to their communities

Betty Benavidez strove to improve access to better education in her west Denver neighborhood. She worked in her local schools and founded action centers, belonged to the Hispanic Education Leadership Program and the West High School PTA, and was district captain for the Democratic party to mobilize Mexican-American voters.

Exploring stellar hydrogen burning via muons and nuclei

The muon is a subatomic particle that resembles an electron but is 200 times heavier. It interacts with nuclei through the weak force, one of the four fundamental forces in the universe. When a muon binds with a deuteron (composed of one proton and one neutron), it forms a system with two neutrons. This process is analogous to proton-proton fusion, where two protons combine to form a deuteron.

Extracellular vesicles study outlines new strategies to combat neurodegenerative diseases

A new study by the University of Barcelona could drive the design of future strategies to regenerate damaged brain areas in neurodegenerative diseases. The study emphasizes the role of neuron-derived extracellular vesicles in the processes that modulate synaptic plasticity and neuronal signaling pathways. In addition, the results outline a new scenario for using these extracellular vesicles...

How proteins roll the dice to determine bee sex

To date it has been unclear exactly how the sex of a bee is determined. A research team from Heinrich Heine University Düsseldorf (HHU) including biologists and chemists has now identified a key gene and the molecular mechanism linked with it. In the current issue of the journal Science Advances, they describe how this process is similar to a game involving two dice.

Ruffed grouse population more resilient than expected, genetic study finds

Despite decades of decline, a genetic analysis of ruffed grouse reveals that Pennsylvania's state bird harbors more genetic diversity and connectivity than expected. The findings suggest that the iconic game bird could be maintained in persistent numbers if appropriate protections are implemented. The study, led by Penn State and Pennsylvania Game Commission researchers, is published in Molecular...
