Can we live longer? Leiden physicist makes discovery in protective layer in genes
With the aid of physics and a minuscule magnet, researchers have discovered a new structure of telomeric DNA. Telomeres are sometimes seen as the key to living longer. They protect genes from damage but get a bit shorter each time a cell divides. If they become too short, the cell dies. The new discovery…

Superselective bonds light up
Rather than one key and one strong lock, biology often uses tens or hundreds of weaker links to bind parts together, such as cells membranes. This allows for selectivity and also reversibility: the binding can also be undone. Researchers first caught this phenomenon using spheres or colloids, and published…

Flu stops when you block the enzyme that cleaves off virus particles
A flu virus could cause a pandemic. And then we would be poorly armed because flu viruses are starting to become resistant to flu medications like Tamiflu. Chemist Merijn Vriends successfully worked on an improved version of such medications. He will be awarded his doctorate on September 12th.

Antibiotic resistance: an economic problem universities could help to solve
Antibiotic resistance is an economic problem. Pharmaceutical companies cannot earn much from antibiotic research, so they do not invest in it. This makes it important that universities do so, says Ned Buijs.
