Slight changes in climate may trigger major abrupt ecosystem responses that are not easily reversible. Some of these responses, including insect outbreaks, wildfire, and forest dieback, may adversely affect people and ecosystems and their plants and animals.

Scientists have found a potentially beneficial use for a once-abandoned compound in the prevention and treatment of neuroblastoma, one of the most devastating cancers among young children.

Scientists have developed a mathematical model of the mating game to help explain why courtship is often protracted. The study shows that extended courtship enables a male to signal his suitability to a female and enables the female to screen out the male if he is unsuitable as a mate.

Preterm infant girls who received a high amount of dietary docosahexaenoic acid (DHA, an omega-3 fatty acid) had higher measures of neurodevelopment than preterm girls who received a standard amount of DHA, but this effect was not seen among preterm boys, according to a study in the Jan. 14 issue of JAMA.
Scientists at deCODE genetics have completed the largest study of ancient DNA from a single population ever undertaken. Analyzing mitochondrial DNA, which is passed from mother to offspring, from 68 skeletal remains, the study provides a detailed look at how a contemporary population differs from that of its ancestors.

We human beings don’t always do as we have been taught, and organizations are poorly prepared for IT security attacks that target human weaknesses. Since it is difficult to change people’s behavior, it doesn’t help to provide training about how to behave securely. Scientists are studying attacks that are considered social engineering in IT contexts.

New research has shown how a massive star can grow despite outward-flowing radiation pressure that exceeds the gravitational force pulling material inward.

Each year, 40 to 60 percent of American adults suffer from chronic back pain. For patients diagnosed with severe degenerative disc disease, neurosurgeons must perform surgery called discectomy — removing the IVD — followed by a fusion of the vertebrate bones to stabilize the spine. Even after all that effort, the patient’s back will likely [...]
Metallic carbon nanotubes have been proposed as interconnects in future electronic devices packed with high-density nanoscale circuits. But can they stand up to the heat?

Abnormalities in genes that repair mistakes in DNA replication may help identify people who are at high risk of developing pancreatic cancer, scientists report in Clinical Cancer Research.
