Engineering human stem cells to model the kidney's filtration barrier on a chip

A team of researchers at Harvard's Wyss Institute has successfully engineered human induced pluripotent stem cells into mature podocytes with over 90% efficiency, paving the way for modeling patient-specific kidney diseases and guiding therapeutic discovery. The development of a functional human kidney glomerulus chip opens up new expe...

Trigger for autoimmune disease identified

Researchers at National Jewish Health have identified Age-associated B Cells (ABCs) as a key driver of autoimmune diseases such as lupus and Crohn's disease. The study found that ABCs cause the immune system to attack organs and tissues, leading to chronic inflammation and tissue damage.

The dark side of helping coworkers

Research suggests that helping coworkers in the morning can cause mental fatigue, leading to reduced helpfulness later in the day and increased self-serving behavior. The study found that employees' mental states switch from other-oriented to selfish in the afternoon, harming not only themselves but also their colleagues.

Training surgeons to teach the public is effective in advancing bleeding control knowledge

A study published by the American College of Surgeons found that 93.79% of trained surgeons believe teaching bleeding control techniques to the public is an appropriate priority. The study's findings suggest that training surgeons can effectively disseminate bleeding control knowledge and teach skills to the general public.

Achieving near-perfect optical isolation using opto-mechanical transparency

Optical isolators are crucial for signal routing and protection in photonic circuits. Researchers demonstrated complete optical isolation within any dielectric waveguide using a simple approach without magnets or magnetic materials. The technique achieves ideal characteristics such as zero loss and perfect absorption, expanding on-chip...

Deciphering an embryo-protecting protein

A team of researchers at Hokkaido University has uncovered the structure of a protein called HLA-G2 that protects embryos from being attacked by their mothers' immune systems during pregnancy. The structure was found to be similar to another class of human leukocyte antigens, suggesting its evolutionary origin.

Mixed valence states in lead perovskites

Scientists have discovered a new class of materials with mixed valence states in lead perovskites, exhibiting charge ordering and high thermopower. The study reveals the key to stabilizing these unusual valence states through tuning the energy levels of Pb 6s and TM 3d orbitals.
