Hydrogen boride (HB) nanosheets can inactivate viruses, bacteria, and fungi within minutes in the dark conditions. By coating surfaces with HB nanosheets, it rapidly inactivates SARS-CoV-2, influenza virus, and other pathogens. The nanosheets work by denaturing microbial proteins, offering a…

Scientists invent breakthrough device to detect airborne signs of disease
If you’ve ever sat waiting at the doctor’s office to give a blood sample, you might have wished there was a way to find the same information without needles.
But for all the medical breakthroughs of the 20th century, the best way to detect molecules has remained through liquids, such as blood….

‘Barcodes’ written into our DNA reveal how blood ages
A new study in the journal Nature explains how age reshapes the blood system. In both humans and mice, a few stem cells, or “clones,” outcompete their neighbours and gradually take over blood production. The blood stem cell reservoir shrinks and becomes dominated by clones which show a…
