Snatched from the air

Researchers have created a novel reaction scheme to efficiently convert carbon dioxide into methanol with minimal energy input. The method utilizes an N-heterocyclic carbene catalyst and silane as the reducing agent, enabling the use of air-borne CO2 as a renewable resource.

Barely legal -- new study into whether alcohol affects perceptions of age

A new study published in the British Journal of Psychology found that consuming alcohol did not affect how men judged the age of women. In fact, researchers found that young females are typically viewed as being older than they actually are. However, make-up and alcohol consumption did have an impact on attractiveness ratings, with you...

6 young ASU faculty earn NSF Career awards

Six Arizona State University faculty members have earned NSF Career awards for their groundbreaking research projects. Junseok Chae is developing protein-based biosensors, while Yi Chen aims to unlock the Internet's hidden data reservoir. Hanqing Jiang seeks to harness carbon nanotubes for practical applications.

Study identifies genes that protect against aging

Researchers at the University of Liverpool have developed a new method to identify genes that help protect the body from age-related changes. The study analyzed over five million gene measurements across multiple tissue types in animals and humans, highlighting key biological mechanisms that allow the body to adapt to aging.

Embargoed news from Annals of Internal Medicine

Researchers found that patient-tailored treatment regimens may have a more positive impact than strict glycemic control in managing type 2 diabetes. Additionally, universal insurance coverage may reduce race-based health care disparities by improving chronic disease control among patients from different racial or ethnic groups.

Repairing a 'bad' reputation?

A team of scientists found that the p75 receptor molecule has a neuroprotective effect on the sympathetic nervous system in mice with Alzheimer's disease, challenging the prevailing view of its harmful role. The study suggests that p75 could be a target for new protocols to manage dementia and memory loss.

Defining the link between anti-TNF therapies and increased tuberculosis

A study by Steffen Stenger and colleagues found that anti-TNF therapies, such as infliximab, decrease the immune system's ability to fight infections, including tuberculosis. The researchers identified a key immune cell subset, CD45RA+ effector memory CD8+ T cells, which plays a major role in targeting the bacterium that causes TB.

Grouping muscles to make controlling limbs easier

A team of researchers at Northwestern University discovered a new approach to control movement in limbs by grouping muscles, which could simplify the restoration of muscle movements in people with paralysis. By reducing the number of variables, this method can achieve similar results as controlling individual muscles.
