Online abortion medication demand highest in states with restrictive abortion policies

A study published in the American Journal of Public Health found that US residents requesting online abortion medications cited difficulty accessing clinical care and personal preferences as reasons for their requests. The demand was highest in states with restrictive abortion policies, with Mississippi leading the way.

Aspirin use after biliary tract cancer diagnosis

Researchers found that aspirin use was associated with a lower risk of death among patients with biliary tract cancer, which includes gallbladder cancer. The observational study included nearly 3,000 patients and suggests that long-term aspirin use may be beneficial for these patients.

Mapping global biodiversity change

A recent study mapping global biodiversity change reveals varying rates of loss and gain in marine and terrestrial ecosystems. The research found that some regions are recovering while others are experiencing significant declines, with changes occurring faster in marine than terrestrial assemblages.

Collective behavior 480 million years ago

Researchers studied fossilized Moroccan Ampyx trilobites and found evidence of orderly lines during storms, suggesting ancient group behavior. This discovery implies that group behavior may have conferred an evolutionary advantage on early animals, allowing them to survive environmental stress.

Embryo's early development revealed in a dish

Bioscientists at Rice University have created a system to form all major cell types of ectoderm in a culture dish, allowing for the most comprehensive analysis yet of signaling pathways that drive patterning. The balance between two signaling pathways, BMP and Wnt, is critical, and cells can take more than one road to get there.

Lessons from Ridgecrest

A comprehensive analysis of the Ridgecrest Earthquake Sequence reveals a web-like network of interconnected faults, challenging standard models of large seismic events. The complexity of the rupture is only clear due to the combined data from orbiting radar satellites and ground-based seismometers.

Giving robots a faster grasp

Researchers at MIT have created an algorithm that significantly speeds up the planning process required for robots to adjust their grasp on objects. The new approach uses motion cones to efficiently calculate feasible pushes and reposition objects in less than a second, compared to traditional algorithms that take over 500 seconds.

The Lancet Haematology: First global estimates suggest around 100 million more blood units are needed in countries with low supplies each year

The global demand for blood transfusions exceeds the available supply by 30 million units annually, with the largest shortages found in lower-income countries. The estimated shortfall varies sharply between countries, with some requiring up to 75 times more blood than their supply can provide.
