A detailed analysis of black carbon — the residue of burned organic matter — in computer climate models suggests that those models may be overestimating global warming predictions.

Researchers have shown that insulin-producing pancreatic beta cells can form after birth or after injury from progenitor cells within the pancreas that were not beta cells.

Historically, scientists have regarded itching as a less intense version of the body’s response to pain, but researchers have now determined that pain and itch actually are regulated by different molecular mechanisms.

Ants specializing on one job such as snatching food from a picnic are no more efficient than “Jane-of-all-trade” ants, according to new research from the University of Arizona in Tucson. The finding casts doubt on the idea that the worldwide success of ants stems from job specialization within the colony.
Scientists found that synaptic size and shape in the center of the spatial memory (i.e. hippocampus) were asymmetrical between synapses receiving input from the left and right hemisphere. Differences were found in the synaptic connections of the learning center of the brain.

New robots develop and display emotions as they interact with humans, and become attached to them.
Scientists have discovered how a genetic switch, known as FoxJ1, helps developing embryos tell their left from their right. While at first glance the right and left sides of our bodies are identical to each other, this symmetry is only skin-deep. Below the surface, some of our internal organs are shifted sideways — heart and [...]

A “chip” or array that can quickly detect disorders such as Down syndrome or other diseases associated with chromosomal abnormalities proved an effective tool in prenatal diagnosis in a series of 300 cases at Baylor College of Medicine, according to an article in the journal Prenatal Diagnosis.

At least one in four of the 697,000 US veterans of the 1991 Gulf War suffer from Gulf War illness, a condition caused by exposure to toxic chemicals, including pesticides and a drug administered to protect troops against nerve gas, and no effective treatments have yet been found, a federal panel of scientific experts and [...]
