Microevolutionary evidence: The eyes have it

A study by the University of South Carolina team found that larger eye size in Daphnia results in an average clutch size increase of one egg beyond the average six eggs. The research team measured the effect of variation in body size, demonstrating that eye size has a greater impact on reproductive success.

Artificial pancreas therapy performs well in pilot study

A pilot study has demonstrated that a mechanical artificial pancreas can better maintain normal blood glucose levels than multiple daily insulin injections in patients with pancreatitis. The treatment combines an AI-powered pump with islet cell transplantation, enabling the transplanted cells to survive longer and produce more insulin.

Grow your own way

A new study suggests that climate change will significantly impact global farming productivity, with a one-sixth decline in production under projected scenarios. Altering crop patterns within countries is key to mitigating these effects, rather than relying on international trade.

Supporting life on Earth

Scientists found evidence of O2 fluctuations in Western Australian rocks, suggesting a temporary increase in atmospheric oxygen levels around 2.5 billion years ago. The data supports the 'Great Oxidation Event' theory, where multiple 'whiffs' of O2 accumulated until a tipping point was crossed.

First-in-man use of virtual reality imaging in cardiac cath lab to treat blocked coronary artery

A team of cardiologists used a virtual reality device to guide the recanalization of a chronically blocked right coronary artery. The procedure was completed successfully with implantation of two drug-eluting stents, demonstrating potential for improved operator comfort and efficiency in interventional cardiology.

ADHD meds may be a prescription for bullying

A new University of Michigan study found that kids and teens taking ADHD medications are twice as likely to be bullied by peers than those without ADHD. Middle school students who sold or shared their medications were four-and-a-half times more likely to be victimized.
