Cu-based small-pore zeolites for deNOx

Cu-based small-pore zeolites have been demonstrated to be promising candidates for NH3-SCR catalysts due to their unique structural features and physicochemical properties. The latest advances in Cu-SSZ-13 applied to the NH3-SCR reaction highlight the significant opportunity presented by zeolite-based catalysts.

The trouble of being tall

Researchers from the University of Copenhagen have studied the giraffe's genome, discovering a key gene FGFRL1 that enables its extraordinary features, such as high blood pressure and dense bones. The study also found that giraffes spend less time sleeping than other mammals due to their unique circadian rhythm regulation.

Text me about cervical cancer

Research from Michigan State University highlights the racial disparity gap in cervical cancer information and follow-up, citing poor provider-patient communication as a key factor. The study suggests that improving education and using digital channels like text messages can help bridge this gap.

AI method can detect precursors to cervical cancer

A new AI-powered screening tool has been developed to detect precursors to cervical cancer in women, particularly in low-income countries where access to skilled pathologists and advanced equipment is limited. The method uses mobile digital microscopy and achieves a sensitivity of 96-100% in identifying patients with precancerous lesions.

Researchers identify barriers to use of surface electromyography in neurorehabilitation

Kessler Foundation researchers identified practical and technical barriers to the use of surface electromyography (sEMG) in clinical neurorehabilitation. They propose a collaborative approach to enable rehabilitation professionals to routinely use sEMG, including hands-on experience, user-friendly technology interfaces, and open-access...

Examining the value of lumbar spine surgery

A prospective clinical study found that patients have three times greater chance of positive outcomes when their surgeons follow evidence-based guidelines for lumbar spinal fusion. The results suggest that patients meeting criteria for successful surgery are three times more likely to experience improved quality of life and reduced pain.

A new, vital player in graft-versus-host disease and organ transplant rejection

A new study reveals that a long noncoding RNA molecule named Linc00402 plays a key role in mobilizing the immune response after bone marrow or solid organ transplantation. The researchers found that inhibiting this RNA could improve outcomes for transplant recipients, reducing the risk of graft-versus-host disease and cancer relapse.

When volcanoes go metal

Researchers at North Carolina State University conducted a pilot study to model ferrovolcanism, the predicted manifestation of planetary volcanism on metallic worlds. They found that metallic lava flows travel 10 times faster and spread more thinly than rocky flows, creating braided channels with smooth, thin layers.

Polystyrene waste is everywhere

Researchers at Ames Laboratory have developed a new method to break down polystyrene waste in a single step, at room temperature, and without harmful solvents. The process involves ball-milling, which generates free radicals that enable the extraction of monomeric styrene from the oligomeric radical-bearing species formed.

Health disparities in type 1 diabetes and COVID-19 infection with Dr. Kathryn Sumpter

A recent study published in The Journal of Clinical Endocrinology & Metabolism found that non-Hispanic black patients with Type 1 diabetes and COVID-19 are almost four times as likely to present with diabetic ketoacidosis compared to white patients. The study highlights the importance of addressing social determinants of health, includ...
