Three-quarters of migrants traveling to US through Mexico experience food insecurity

A survey of 95 Central American migrants found that 74% experienced food insecurity, with factors including days in transit and travel companion illness. The researchers offer potential remedies for strengthening migrants' access to food, including information on procuring nutrition and prioritizing inexpensive food.

Discovery of accurate and far more efficient algorithm for point set registration problems

A new algorithm has been discovered that can accurately register two point sets consisting of millions of points in a fraction of the time taken by conventional methods. The algorithm's accuracy is not compromised despite using approximations, and it has wide-ranging applications in computer graphics and computer vision.

Reducing problem behaviors for children with autism

A University of Missouri researcher has created a new approach to reducing problem behaviors in children with autism spectrum disorder. The flexible intervention technique emphasizes momentary check-ins, allowing parents and caregivers more flexibility to implement the strategy. This can help minimize self-inflicted harm and social sti...

The thrust of the problem

A team of researchers from UC Riverside has determined a new geometric model for the Main Himalayan Thrust fault, allowing officials to better prepare for future earthquakes. The study found that the fault is still accumulating stress and may have increased the likelihood of another big earthquake nearby.

Health care provider deserts may leave patients in the cold

Researchers found that people with ACA health insurance are more likely to find themselves in 'artificial provider deserts,' areas with limited coverage, and must travel further to access care. The study highlights the need for consumers to carefully consider their insurance options to make informed decisions about their healthcare.

Private boats in the Mediterranean have extremely high potential to spread alien species

A study by the University of Pavia found that Mediterranean private boats have a high potential to spread alien species through biofouling. Boats traveling to new marinas were likely to be transporting alien species, with visible biofouling in niche areas such as ladders and propellers being key predictors of high species richness.

Immune response depends on mathematics of narrow escapes

A new study reveals the narrow escape problem, a classic math puzzle, plays a key role in determining immune responses. The unique shape of T cells creates a close-contact zone for triggering molecules, and the size of this zone depends on the surface protrusions, keeping the process sensitive to invaders.

Fertilizer feast and famine

A UC Davis study highlights the need for a coordinated international policy to address the global nitrogen problem. The research suggests that applying fertilizers more precisely, removing pollution from the environment, and empowering consumers to think about sustainable food options can help alleviate the issue.

Lure of the 'loot box' looks a lot like gambling

A new study by University of British Columbia researchers found a correlation between excessive engagement with loot boxes and measures of problem gambling, but not problem video gaming. Loot box use was associated with risky gambling behaviours, suggesting that the feature may be contributing to gambling-like problems in gamers.

Harmonization of resting-state functional MRI data across multiple imaging sites

Researchers developed an effective harmonization method to reduce site-related differences in resting-state fMRI data, reducing bias by 29% and improving signal-to-noise ratios by 40%. This allows for the development of practical brain-circuit-based biomarkers of psychiatric disorders regardless of imaging site.

Mayo Clinic researchers review modern cases of leprosy

Researchers identified nine patients with leprosy treated at Mayo Clinic from 1994 to 2017, revealing common factors such as Micronesian lineage and extensive travel while immunosuppressed. The study highlights the importance of treatment and vigilance for immunosuppressed individuals traveling to areas with high rates of leprosy.

Internet-based interventions can help reduce problem drinking

A meta-analysis of 19 randomized controlled trials found that Internet-based interventions significantly reduced mean weekly alcohol consumption and improved adherence to low-risk drinking limits. Older adults and those with lower education levels showed greater treatment response, while human-guided interventions had a stronger impact...

New traffic rules in 'Graphene City'

Researchers at Penn State have developed a system to manipulate electrons based on their energy and momentum, enabling controlled partitioning of electron flow. This technology could potentially be used to create 'color-coded' roads for electrons, revolutionizing the field of electronics.

How prions invade the brain

Researchers used genetically modified mice with a highly permeable blood-brain barrier to test whether prions in blood can enter the brain. Their results suggest that passage of prions through the blood-brain barrier may not be relevant to disease development. Instead, prions likely reach the brain by traveling along nerves.
