McPhee plans to examine oligodendrocytes, cells responsible for white matter in the brain, to improve understanding of Canavan disease mechanisms.
Researchers analyze over 59,000 grains from Acfer 094 meteorite and identify nine specks of silicate stardust. The discovery provides information about stellar sources, nuclear processes, and the physical and chemical compositions of stellar atmospheres.
Scientists have discovered that early oceans were devoid of oxygen for billions of years, with a team developing a method to detect signs of ancient oxygen in rocks. The study sheds light on the history of our planet's oceans and could have significant implications for understanding evolution and the origins of life.
A study found that early treatment with thrombolytics can significantly improve stroke recovery rates, with patients treated within 90 minutes of symptom onset showing the most improvement. The study also suggests that t-PA given up to 4 hours after symptoms may be beneficial, but the effect diminishes later.
Researchers found obese children had shorter treadmill times and lower endurance compared to non-obese peers. Obesity also increases the risk of type 2 diabetes, joint problems, and atherosclerosis in adolescents.
Research found that young children who consumed moderate amounts of dairy products and fat experienced less weight gain than those on low-fat or high-fat diets. Increased consumption of fruits and vegetables was also associated with lower gains in body fat.
The new centre will combine functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG) to study brain processes involved in everyday mental tasks. Research at the centre may lead to improved treatments for conditions like strokes, multiple sclerosis, and schizophrenia.
The World Health Organization's (WHO) global tuberculosis control strategy, DOTS, is facing challenges in meeting its 2005 targets. A significant case-detection gap exists between estimated annual incident cases and reported cases under the DOTS strategy. The WHO recommends four key actions to address this issue, including equipping na...
Neutrophils can produce NETs, a net-like structure that binds, disarms, and kills bacteria. This novel defense mechanism was discovered by researchers at the Max Planck Institute for Infection Biology.
The study found that protective factors such as high academic achievement and strong community ties can foster pro-social behaviors and prevent antisocial behavior. Additionally, good family management practices were shown to significantly reduce the likelihood of violence among aggressive youth.
A study by Sergei Mirkin and Maria Krasilnikova found that faulty DNA replication causes the sequence to become unstable when it exceeds 40 repeats, leading to symptoms such as muscle weakness and heart disease in neurological diseases like Friedreich's ataxia.
A team of physicists and engineers created metamaterials that respond magnetically to terahertz radiation, extending their properties to the terahertz range. This discovery has the potential to enable new applications in areas like weather guidance, security, and biomedical imaging.
