New surgical strategy offers hope for repairing spinal injuries

Repairing spinal injuries is a difficult business. Scientists previously developed a new surgical technique to reconnect sensory neurons to the spinal cord after traumatic spinal injuries. Now, they have gained new insight into how the technique works at a cellular level by recreating it in rats. The technique succeeds because offshoots from the spinal cord grow into the implanted sensory neurons to complete a spinal circuit.

'Missing lead' in Flint water pipes confirms cause of crisis

A study of lead service lines in Flint's damaged drinking water system reveals a Swiss cheese pattern in the pipes' interior crust, with holes where the lead used to be. The findings support the generally accepted understanding that lead leached into the system because that water wasn't treated to prevent corrosion. Researchers say the findings underscore how important uninterrupted anti-corrosion treatment is for the aging water systems that serve millions of American homes.

A brain penetrant drug -- a small-molecule mimetic of BDNF, or brain derived neurotrophic factor -- is able to improve brain performance in Rett syndrome mice -- specifically synaptic plasticity in the hippocampus and object location memory. The hippocampus is involved in learning and memory.
Estrogen regulates pathological changes of bones via bone lining cells

The female sex hormone estrogen plays an important role in the structural stability of bones. To date, however, it had been unclear exactly which cells were involved in the hormone's protective function. Researchers have now shown for the first time that estrogen uses bone lining cells to regulate the expression of the protein RANKL. Estrogen deficiency leads to uncontrolled expression of RANKL, which can trigger pathological changes in the bones.

Two de-identification methods, k-anonymization and adding a 'fuzzy factor,' significantly reduced the risk of re-identification of patients in a dataset of 5 million patient records from a large cervical cancer screening program in Norway.
Sleep or sex? How the fruit fly decides

Choosing between sex or sleep presents a behavioral quandary for many species, including the fruit fly. A multi-institution team has found that, in Drosophila at least, males and females deal with these competing imperatives in fundamentally different ways.
