The space between us

A study from Washington University in St. Louis highlights the importance of spatial aspects of biodiversity for healthy forest functioning. The research shows that tree beta diversity, a measure of site-to-site variation in species composition, is stronger than other components of biodiversity at larger scales.

Study examines why the memory of fear is seared into our brains

Researchers discovered that stress neurotransmitter norepinephrine stimulates a specific population of inhibitory neurons in the amygdala to generate a repetitive bursting pattern of electrical discharges. This leads to the formation of fear memories, which can be difficult to forget due to their association with traumatic experiences.

In bias we trust?

Researchers at MIT found that explanation methods used to aid human decision-makers in high-stakes situations often have lower accuracy for minoritized subgroups. The fidelity of these explanations varies dramatically between subgroups, with the quality often significantly lower for women and Black people.

The surprising musical dynamics of a lava lake on Kīlauea volcano

Researchers from the University of Oregon studied a persistent lava lake at Kīlauea's summit, finding that seismic signals encode resonance of magma sloshing in and out of the shallow magma chamber. The study provides new insights into volcanic gas migration and magma temperature, shedding light on the volcano's dynamics.

Davis Instruments Vantage Pro2 Weather Station

Davis Instruments Vantage Pro2 Weather Station offers research-grade local weather data for networked stations, campuses, and community observatories.

At least 2,000 species of reptiles are threatened

The first international study of its kind assesses the status of all reptile species, revealing that at least 2,000 species are threatened with extinction. The study found that 50% of turtle and crocodile species face extinction threats, while 30% of forest-dwelling reptiles and 14% of arid area reptiles are in danger.

Could time limits on opioid prescriptions reduce misuse?

A Michigan study reveals that hundreds of thousands of surgical and dental opioid prescriptions are filled long after writing, but a state law helped reduce this trend. The authors suggest tightening state laws to prevent or reduce misuse associated with delayed dispensing of opioids.

Bacteria-killing drills get an upgrade

Researchers at Rice University have developed molecular machines that can kill bacteria using visible light, targeting gram-negative and gram-positive bacteria. The breakthrough study uses rotors spinning at millions of times per second to break up biofilms and persister cells, making these infections more treatable.
