The method, likened to uprooting a tree stump, creates nanopores in thin membranes for DNA analysis and molecule detection.
Researchers used directed evolution to boost bacterial tolerance to industrial spray-drying, improving survival by 1000-fold. The genetic basis of this newfound toughness was linked to a mutation in the pepC gene, which truncates the protein and likely abolishes its enzymatic activity.
Researchers have documented glycan-glycan interactions between gangliosides and their impact on EGF receptor dimerization and activation. This study provides a new mechanism regulating EGFR activity, which may have implications for future cancer research.
Transparent ferroelectric ceramics face trade-offs between transparency and functionality due to multiscale structural features. Strategies such as pressure-assisted sintering, grain refinement, and domain engineering can reduce optical scattering, but may alter polarization switching, piezoelectric activity, and thermal stability.
Phosvitin phosphopeptides from chicken egg yolks demonstrate strong antioxidative and neuroprotective effects, reducing ROS and increasing cell viability in SH-SY-5Y cells. Further research is needed to confirm their value as potential food/nutraceutical ingredients and determine their dosage and safety in humans and animals.
Researchers found that a combination of sucrose and supercritical carbon dioxide can improve egg white protein foam's foaming ability and stability. The treatment increases foaming capacity and preserves stability, enabling better freeze-thaw resistance in liquid egg white products.
A study published in JAMA Network Open reveals that nearly 1 in 3 women in their 20s have never been screened for cervical cancer, with 45% of this age group unvaccinated against HPV. The trend is particularly concerning among uninsured women, those living in the South, and racial minorities.
A low-carb ketogenic diet was found to improve liver health and blood sugar control more significantly than other diets, reducing liver fat by 67% and lowering blood glucose measurements by 20%. The study suggests that weight loss alone is not enough to combat metabolic health risks and that dietary choice remains an important factor.

A UCLA study found that patients with cancer who used biosimilars had lower average monthly costs for insurers and patients, with savings of $3,820 for insurers and $39.50 for patients. The study also found that biosimilar entry led to lower prices and declining market share for the original branded biologic drugs.
The study found that cervical cancer screening rates among US women increased for both age groups 21-29 years and 30-65 years between 2005-2023. Sociodemographic disparities were also identified in the study, highlighting the need for targeted interventions to improve screening rates among underrepresented groups.
A quality improvement study found that a publicly available MRSA prevention program toolkit materials were associated with a 65% decrease in hospital-onset MRSA bacteremia laboratory-identified events.
