Study identifies universal blueprint for mammalian brain shape

Researchers have identified a universal blueprint for mammalian brain shape, describing the cerebral cortex as following a fractal pattern across species. The study suggests that cortices across primate species resemble this universal scaling law and self-similarity, revealing a common set of mechanisms governing cortical folding.

How obstetric interventions affect the birthing experience

A recent study found that vaginal birth without medical intervention results in the highest level of satisfaction among mothers, while obstetric interventions lead to lower scores. The researchers emphasize the importance of support and empowerment in mitigating negative experiences during childbirth.

How researchers turn bacteria into cellulose-producing mini-factories

Researchers developed an approach to boost cellulose production in bacteria by inducing mutations through UV-C light. This method produced bacterial variants that generate up to 70% more cellulose than the original form, paving the way for industrial-scale production of sustainable materials.

Youth suicide and preceding mental health diagnosis

A cross-sectional study found that 60% of youth suicide decedents lacked a preceding mental health diagnosis, with racial and ethnic minorities having lower odds of diagnosis. The study highlights the need for equitable mental health identification and lethal means counseling to prevent youth suicide.

Researchers develop general framework for designing quantum sensors

A protocol has been designed to harness the power of quantum sensors, allowing for fine-tuning of quantum systems to sense signals of interest. The framework uses a combination of qubits and bosonic oscillators to create sensors that are vastly more sensitive than traditional sensors.
