MD Anderson and Phoenix SENOLYTIX announce strategic cross-licensing agreement to enhance inducible switch technologies for cell and gene therapies

Phoenix SENOLYTIX and MD Anderson Cancer Center announced a cross-licensing agreement to further develop inducible switch technologies for use in cell and gene therapies. The partnership will enhance the development of these technologies, which can be used as safety features to regulate cell therapy activity.

Novel accurate approach improves understanding of brain structure in children with ADHD

Researchers developed a new method to correct for variations in brain imaging measurements, reducing bias and increasing the accuracy of studies on ADHD. The traveling-subject method demonstrated reduced measurement bias while maintaining sampling bias, revealing decreased brain volume in critical regions for cognitive functions.

Worse outcomes with aspirin in high-risk chronic coronary syndrome patients who require long-term anticoagulation

Adding aspirin to long-term anticoagulation therapy increased the risk of cardiovascular events, death, and major bleeding in patients with chronic coronary syndrome who required anticoagulation. The AQUATIC trial found that aspirin significantly increased all-cause mortality and major cardiovascular events in this high-risk population.

Developing a stable and high-performance W-CoMnP electrocatalyst by mitigating the Jahn-Teller effect through W doping strategy

The research team developed a simple template-free method to prepare cobalt-based and manganese-based precursors, and then doped W during the synthesis of transition bimetallic phosphides. The resulting catalyst exhibits excellent bifunctionality and can be utilized as an electrode in anion exchange membrane water electrolyzers.

Singapore's young women show 'skinny-fat' risks typically seen in older age

A comprehensive study of Singaporean women in their 20s-30s found that nearly one in four healthy-weight Chinese women already have low muscle mass and weaker bones, despite appearing healthiest by BMI standards. The study highlights the need for healthcare approaches that consider body composition beyond simple weight measurements.

What makes an opera singer stand out? New research decodes 'black box' of opera evaluation

A new study found that vibrato is the most significant vocal attribute in determining an opera singer's score, while acoustic features like SPR and HNR have a greater impact than previously thought. The research provides objective insights into how judges evaluate performances and offers tools for vocal training.
