New research demonstrates that bicycles do not significantly reduce passenger car travel speeds on low speed, low volume urban roads without bicycle lanes. The research shows that differences in vehicle speeds with and without cyclists were generally on the order of 1 mph or less - negligible from a practical perspective.

Researchers have combined two immunotherapy strategies into a single therapy and found, in studies in human cells and in mice, that the two together are more effective than either alone in treating certain blood cancers, such as leukemia.

Deleting a key gene in mice in just their fat made tissues throughout these animals insulin resistant, in addition to other effects, a new study shows. The findings could shed light on Type 2 diabetes and other insulin resistance disorders, which remain poorly understood despite decades of study.

We inherit half of our genes from each parent. For their function of most genes, it doesn't matter which parent a gene comes from. But this is not true for all genes: about 150 genes are subject to ''genomic imprinting''. They are active either only if inherited from the mother, or only father. Most ''imprinted'' genes are important for our development. New research shows that brain cells react differently to genomic imprinting.

Researchers have, for the first time, acquired optical coherence tomography (OCT) images of the curved layers of a person's cornea with cell-level detail and a large viewing area. The new OCT instrument enables improved monitoring of eye diseases as well as general health conditions such as diabetes, which alter the density of nerves in the cornea.
