How far is Fukushima nuclear accident contaminated water from us?

A team from Tsinghua University developed analysis models to simulate the diffusing process of radioactive water in oceans. The pollutants are expected to cover almost the entire Pacific Ocean within 3600 days, with a contamination center moving eastward along the 35°N latitude line.

Widespread vaginal condition could lead to emergency caesarean section

A new study by researchers at the University of Copenhagen found that an imbalance in vaginal bacteria is associated with a higher risk of emergency caesarean section. The study analyzed 1,396 samples from 736 pregnant women and discovered that those with greater levels of imbalance were more likely to deliver via C-section.

Headwater refuges

A team studied wildfire impacts on streams in parts of the Los Padres National Forest, finding that stream headwaters serve as refuges for aquatic species during fires and droughts. The study's findings suggest that protecting these areas is crucial for maintaining watershed resilience and biodiversity.

Eye imaging technology breaks through skin by crossing beams

Duke researchers developed a method to increase the depth of view of optical coherence tomography (OCT), allowing for clear images from beyond a millimeter beneath the skin's surface. The new technique, known as dual-axis OCT, tilts the light source and detector to collect more scattered light from deep tissues.
