Phys.org / Two white-blooded fish, two paths: Icefish and noodlefish independently lose red blood cell function

Antarctic icefish are famous for living without red blood cells, but they are not alone. A species of needle-shaped, warm-water fish called the Asian noodlefish also lacks hemoglobin and red blood cells. Like icefish, its ...

Phys.org / Nanoparticle therapy reprograms tumor immune cells to attack cancer from within

Within tumors in the human body, there are immune cells (macrophages) capable of fighting cancer, but they have been unable to perform their roles properly due to suppression by the tumor. A KAIST research team led by Professor ...

Medical Xpress / AI model predicts B cell reactivity to neoantigens for improved cancer vaccines

Neoantigens are unique markers that distinguish only cancer cells. By adding B cell reactivity, cancer vaccines can move beyond one-time attacks and short-term memory to become a long-term immunity that "remembers" cancer, ...

Medical Xpress / Costs pose hurdle for promising new hepatitis C lab test

A new rapid test for hepatitis C could help identify many more patients who could be cured of the deadly disease, but its use may be limited unless insurers' reimbursement rises to cover its high cost, according to researchers ...

Medical Xpress / Creating cells that help the brain keep its cool

Researchers at Lund University in Sweden have created a method that makes it possible to transform the brain's support cells into parvalbumin-positive cells. These cells act as the brain's rapid-braking system and are significantly ...
