Medical Xpress / Leftover COVID spike fragments kill crucial immune cells but are less deadly in omicron

New research shows that after the body's defenses kill the virus behind COVID-19, leftover digested chunks of SARS-CoV-2 spike protein can target specific immune cells based on their shape. The revelations could explain why ...

Tech Xplore / Core-shell anodes boost sodium-ion battery efficiency and capacity

Sodium-ion batteries are considered a promising, sustainable alternative to lithium-ion batteries. However, high storage losses during the first charging cycle have slowed down their development so far. Researchers at the ...
