One in nine older adults who use cannabis meet criteria for cannabis use disorder

A study from the University of California San Diego School of Medicine found that 11.4% of older adults who used cannabis in the past year met the criteria for cannabis use disorder (CUD). This condition is characterized by a pattern of cannabis use that causes problems or interferes with daily life. The study highlights the importance...

By shaping and shrinking light, engineers alter a material's magnetic properties

Researchers at the University of California San Diego have developed a new approach to switch magnetic states using light, which could lead to faster and more efficient data storage. By shaping and shrinking light, they were able to overcome limitations of previous methods and achieve optical switching in thicker magnetic materials.

Is the universe twisted? A new check on a possible twist in the universe’s oldest light

Researchers developed a method to test cosmic uncertainty in the universe's oldest light, which could provide evidence for physics beyond the Standard Model. The team compared maps from different detectors to establish the calibration pattern, finding consistency with existing analysis.

Rules of the school

Researchers at the University of California San Diego used computational models and virtual reality to study the social interaction rules of schooling fish. They found that individual fish 'copy' the movement direction of a randomly-chosen nearby neighbor, leading to highly dynamic behavior in groups.

Inexpensive reflective tiles pave the way for cost effective millimeter wave wireless communications

Researchers at the University of California, San Diego, have developed an inexpensive solution to the path-obstruction problem in millimeter wave wireless communications. Their passive reflective tiles, called FlowForm, can nearly double average data rates indoors and double wireless coverage area in challenging environments, matching ...

As New World screwworm returns to the U.S., UC San Diego and San Diego County team up to track the risk

The University of California San Diego and San Diego County have developed a tool to track the New World screwworm, a parasitic fly whose larvae feed on living tissue. The dashboard combines reports of confirmed detections, environmental suitability, and media coverage to estimate risk nationwide.

Corn stalks. It’s what’s for dinner … If you’re a microbe.

Engineers have created a bacterium that can consume all three major sugars present in corn stalks, opening up possibilities for more efficient biomanufacturing processes. The new strain of Pseudomonas putida was developed using an automated culturing platform and can potentially be used to produce valuable molecules like indigoidine.

Mindfulness-based therapy for opioid misuse offers massive return on investment

A new study reveals that Mindfulness-Oriented Recovery Enhancement (MORE) is highly effective in reducing opioid misuse and costs. The therapy, which combines mindfulness skills to regulate craving and pain, has been shown to provide $12 in cost savings for every dollar spent, with potential economic benefits of over $324,000 per patient.

First ever reported cryo-EM visualization of E. coli TGT structure

Researchers have determined the cryo-electron microscopy (cryo-EM) structure of E. coli TGT, overturning a prevailing model for bacterial TGT function. The study reveals the enzyme binds to two tRNAs, providing a more complete picture of protein modification and potential antivirulence targets.

What explains gender pay gaps in academia?

A new study found that faculty women in academia earn 23% less than men, narrowing to 4.3% when accounting for field and academic rank. The research suggests that transparency alone is not enough to eliminate pay gaps, and representation does not guarantee equal pay.

Drug candidate could help L-dopa work better for patients with Parkinson’s

Researchers have developed a new drug candidate, SB-0110, that boosts L-dopa's benefits while reducing dyskinetic side effects in animal models of Parkinson’s disease. The compound preserves the gene-activity patterns tied to L-dopa’s benefits while counteracting biological changes associated with dyskinesia.
