Study finds support for second look sentencing

A new study found widespread support for second look sentencing, with respondents backing the approach regardless of age. Factors such as petitioners' intent to reform and victim support increased support for release. The study suggests that releasing reformed individuals can reduce costs and enhance public safety.

Complications in pregnancy linked to increased risk of heart disease

A new study by researchers from Lund University in Sweden has found that women with pregnancy complications are at an increased risk of heart disease. The study revealed that women with pre-eclampsia and gestational hypertension had visible atherosclerosis of the coronary arteries, compared to those without complications.

Toward practical quantum optics: multiphoton qubits from LNOI

Researchers from Nanjing University have proposed the first scheme to practically generate N-photon states deterministically using a lithium-niobate-on-insulator platform. The scheme involves deterministic parametric down-conversion and demonstrates feasibility for generating multiphoton qubit states.

Solar-powered gel filters enough clean water to meet daily needs

Researchers at Princeton University have developed a new solar absorber gel technology that can filter pollutants from water, producing almost fourfold more filtration rate than its predecessor. The device can provide enough clean water to meet daily demand in many parts of the world.

Extreme earners are not extremely smart

A new study from Linköping University found that cognitive ability levels do not differentiate wages among top earners, contrary to common defenses of their extraordinary earnings. Average ability plates at a modest level of +1 standard deviation above average cognitive ability for those earning above €60,000 annual wage.

Less lung tissue removal needed for early-stage cancer, study finds

A phase 3 clinical trial of nearly 700 patients with early-stage lung cancer found that sublobar resection surgery, removing part of the affected lobe, was as effective as traditional lobectomy in terms of disease-free and overall survival. Patients who underwent sublobar resection also showed modestly better lung function.

The geometry of conflict

Conflicts between divergent goals can continue indefinitely through evolutionary time, causing devastating damage to complex organisms and social structures. Modular design is a crucial enabler of complex adaptation and transformative changes in social organisation.
