Just as fly paper captures insects, an innovative new device with nano-sized features is able to grab cancer cells in the blood that have broken off from a tumor. These cells, known as circulating tumor cells, or CTCs, can provide critical information for examining and diagnosing cancer metastasis, determining patient prognosis, and monitoring the effectiveness [...]

Although morphine has been the gold-standard treatment for postoperative and chronic cancer pain for two centuries, a growing body of evidence is showing that opiate-based painkillers can stimulate the growth and spread of cancer cells. Two new studies advance that argument and demonstrate how shielding lung cancer cells from opiates reduces cell proliferation, invasion and [...]

Engineering researchers have developed a unique and robust method to prevent cloning of passive radio frequency identification tags. The technology, based on one or more unique physical attributes of individual tags rather than information stored on them, will prevent the production of counterfeit tags and thus greatly enhance both security and privacy for government agencies, [...]

At birth, children with Down syndrome aren’t developmentally delayed. But as they age, these kids fall behind. Memory deficits inherent in Down syndrome hinder learning, making it hard for the brain to collect experiences needed for normal cognitive development. Scientists have now demonstrated a possible new approach to slowing the inevitable progression of cognitive decline [...]

Viruses are well known for attacking humans and animals, but some viruses instead attack bacteria. Researchers are exploring how hungry viruses, armed with transformer-like weapons, attack bacteria, which may aid in the treatment of bacterial infections.

The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions — a finding with potentially wide implications for [...]

Indoor smoking bans have forced smokers at bars and restaurants onto outdoor patios, but a new study suggests that these outdoor smoking areas might be creating a new health hazard.

New research points the way to a technology that might make it possible to harvest much of the wasted heat produced by everything from computer processor chips to car engines to electric power plants, and turn it into usable electricity.

Scientists have confirmed that blindness causes structural changes in the brain, implying that the brain may re-organize itself functionally in order to adapt to a loss in sensory inputs.
