Scientists regenerate neurons in mice with spinal cord injury and optic nerve damage

Each year thousands of patients face life-long losses in sensation and motor function from spinal cord injury and related conditions in which axons are badly damaged or severed. New research in mice shows, however, that gains in functional recovery from these injuries may be possible, thanks to a molecule known as Lin28, which regulates cell growth.

Better understanding of nature's nanomachines may help in design of future drugs

Many of the drugs and medicines that we rely on today are natural products taken from microbes like bacteria and fungi. Within these microbes, the drugs are made by tiny natural machines known as nonribosomal peptide synthetases (NRPSs). A research team has gained a better understanding of the structures of NRPSs and the processes by which they work. This improved understanding of NRPSs could potentially lead to the creation of new potent antibiotics, immunosuppressants and other modern drugs.

Now, researchers have revealed how a general anesthetic called isoflurane weakens the transmission of electrical signals between neurons, at junctions called synapses.

Structure of biocatalysts depends on whether they are in cells or test tubes

The structure of enzymes determines how they control vital processes such as digestion or immune response. This is because the protein compounds are not rigid, but can change their shape through movable 'hinges.' The shape of enzymes can depend on whether their structure is measured in the test tube or in the living cell. This is what physicochemists discovered about YopO, an enzyme of the plague pathogen.

Segregation and local funding gaps drive disparities in drinking water

The fragmentation of water service in the US among thousands of community systems, most of which are small and rely on local funding, leaves many households vulnerable to water contamination or loss of service as droughts become more frequent, a new analysis finds. Households in low-income or predominantly minority neighborhoods face the highest risks. Making sure their taps don't run dry will require a fundamental re-evaluation of how water systems are managed and funded.
