Minor differences in the timing of cell proliferation can explain the large differences found in the eyes of two species — owl monkeys and capuchin monkeys — that evolved from a common ancestor.
Scientists have pinpointed a new class of gene mutations, which identify cases of childhood acute lymphoblastic leukemia that have a high risk of relapse and death. The finding suggests specific drugs that could treat this high-risk leukemia subtype in children, particularly because such drugs are already in clinical trials for similar blood diseases in adults.

By creating a model of the active site found in a naturally occurring enzyme, chemists have described a catalyst that acts like nature’s most pervasive hydrogen processor.

Investigators have cracked one of clinical medicine’s enduring mysteries — what happened to the tuberculosis vaccine. The once-effective vaccine no longer prevents the bacterial lung infection that kills more than 1.7 million people worldwide each year. Their solution could lead to an improved TB vaccine and also may offer a novel platform for vaccines against [...]
A novel method of reconstructing missing data will shed new light on how and why our climate moved us on from ice ages to warmer periods as researchers will be able to calculate lost information and put together a more complete picture.
One well-known and often deadly consequence of alcohol intoxication is impaired driving. Yet still today, it is difficult for even trained observers to fully identify “intoxication,” given that so many factors contribute to it. This review examines the very definition of intoxication, as well as methods designed to prevent impaired driving.

Using ESO’s Very Large Telescope, astronomers have succeeded in measuring the size of giant galaxy Messier 87 and were surprised to find that its outer parts have been stripped away by still unknown effects. The galaxy also appears to be on a collision course with another giant galaxy in this very dynamic cluster.

Researchers have uncovered a gene signature that may help predict clinical outcomes in certain types of breast cancer. They report that this gene signature — which is associated with the transforming growth factor-beta (TGF-²) signaling pathway — correlates with reduced relapse-free survival in patients with breast cancer, especially in those with estrogen receptor (ER) positive [...]

Many scientists currently think at least 5 percent of humanity’s carbon footprint comes from the concrete industry, both from energy use and the carbon dioxide byproduct from the production of cement, one of concrete’s principal components.

Cancer and cell biologists have identified a new molecular pathway key to the development of invasive prostate cancers.
