Social, behavioral modifications can be positive trigger to mitigating gun violence

Researchers found that active shooter drills can cause emotional distress and uncertainty among students, highlighting the need for evidence-based strategies. Social-emotional learning programs and a safe, supportive environment are key to reducing gun violence in schools, according to West Virginia University Professor Keith Zullig.

'Message in a bottle' tracks plastic pollution

Researchers from the University of Exeter and ZSL used GPS and satellite tags in plastic bottles to track plastic pollution in the Ganges river and Bay of Bengal. The study found that plastic pollution can travel thousands of kilometers in just a few months, with some bottles traveling up to 2,845km in 94 days.

Natural three-dimensional nonlinear photonic crystal

Scientists have developed a natural potassium-tantalate-niobate (KTN) perovskite nonlinear photonic crystal with 3D spontaneous Rubik's domain structures, enabling compensation of phase-mismatch along arbitrary directions. This breakthrough paves the way for new applications in optical communications, quantum entanglement sources, and ...

Optimal horse racing speed pinpointed by mathematical analysis

Mathematical analysis reveals optimal Thoroughbred horse racing speed by analyzing track data and considering factors such as course length, surface type, and weather conditions. The study provides insights into the physical limitations of horses and the importance of course-specific factors in determining optimal speed.

Common neural circuit and potential target for anxiety and obsessive-compulsive disorder

A glutamatergic neuronal circuit from the prelimbic prefrontal cortex to the nucleus accumbens is responsible for co-occurring anxiety and obsessive-compulsive-like behaviors. Histamine presynaptic H3 receptor activation in this circuit ameliorates stress-induced anxiety and obsessive-compulsive-like behaviors.

Reconstruction of eye tissue gives new insight into outer retina

Scientists at the University of Southampton have made a breakthrough in reconstructing eye tissues from the outer retina using serial block face scanning electron microscopy. The study provides a clear picture of the 3D organisation of the retinal pigment epithelium, which could help understand causes of damage leading to sight loss.

CNIC scientists identify a new diagnostic and therapeutic target for cardiovascular disease

Researchers at CNIC have identified mitochondrial protein ALDH4A1 as a potential marker for cardiovascular disease diagnosis and a possible therapeutic target. The study found that ALDH4A1 accumulates in plaques and its plasma concentration is elevated in patients with carotid atherosclerosis, suggesting it as a biomarker.

Rethinking race and kidney function

A new study from Harvard Medical School forecasts the impact of eliminating race from kidney function formulas on Black patients with kidney disease. The analysis suggests that removing race-based adjustments may lead to earlier diagnoses and better access to care, but also restricts access to certain medications and treatments.
