Are we trading energy conservation for toxic air emissions?

A Yale University study finds that compact fluorescent lighting can increase mercury emissions in certain countries and US states, offsetting energy conservation gains. The switch to CFLs may reduce emissions in some areas, such as Estonia and China, but increase them in others, like South America and parts of Europe.

Disease diagnosis in just 15 minutes

A team at the University of Leeds has developed a fast and affordable biosensor technology to detect biomarkers for various diseases. This technology can potentially replace current testing methods that take hours to complete and require specialized equipment.

Learning to shape your brain activity

A unique study successfully used instrumental sensorimotor rhythm conditioning (ISC) to improve sleep spindles, decrease sleep onset latency, and increase memory performance. Participants who trained their brain activity to shape SMR amplitude showed significant improvements in sleep quality and memory performance after two weeks.

Treatment window expanded

A new study published in the New England Journal of Medicine found that patients can still benefit from dissolving blood clots in the brain up to 4.5 hours after a stroke. The study, known as ECASS 3, involved 826 patients who received either the thrombolytic drug alteplase or a placebo, with better response rates and no increased mort...

When cells go bad

Researchers found that when a single telomere is lost, it can cause many abnormalities in a cell's chromosomes, leading to cancer. A new treatment route for cancer may be possible by interfering with the process of adding new telomeres.

The green Sahara, a desert in bloom

Researchers discovered three periods of high vegetation cover in the Sahara Desert over the past 120,000 years, tied to changes in Earth's rotation axis and increased precipitation. Computer model simulations support these findings, suggesting a potential expansion of vegetation in the region under human-driven climate change.

A new 10-year vision for glaucoma

The article discusses a global summit of leading glaucoma specialists who gathered to discuss key needs and opportunities in advancing therapies for patients. The summit highlighted the need to advance beyond traditional IOP-lowering therapies and explore new approaches, including innovative drug delivery systems and novel biomarkers.

Ecologists allay fears for farmland birds from wind turbines

A new study found that wind turbines do not significantly affect the distribution of seed-eating birds and corvids. However, common pheasants were the only species whose distribution was impacted by the turbines. This research is crucial for reconciling EU energy targets with biodiversity conservation efforts.
