Astrocytes Show Unexpected Role in Brain Plasticity
When we’re born, our brains have a great deal of flexibility. Having this flexibility to grow and change gives the immature brain the ability to adapt to new experiences and organize its interconnecting web of neural circuits. As we age, this quality, called “plasticity,” lessens. Now, a study has shown that supportive astrocyte cells help enable this plasticity.

Curing Drug-Resistant Infections Without Antibiotics
Biochemists, microbiologists, drug discovery experts and infectious disease doctors have teamed up in a new study that shows antibiotics are not always necessary to cure sepsis in mice. Instead of killing causative bacteria with antibiotics, researchers treated infected mice with molecules that block toxin formation in bacteria.

Tracking Down Missing-in-Action Multiple Sclerosis Genes
Previous work by the International Multiple Sclerosis Genetics Consortium (IMSGC) has identified 233 genetic risk variants. However, these only account for about 20% of overall disease risk, with the remaining genetic culprits proving elusive. A new study has tracked down four of these hard-to-find genes.
