Researchers have discovered an entirely new mechanism for making common electronic materials emit laser beams. The finding could lead to lasers that operate more efficiently and at higher temperatures than existing devices, and find applications in environmental monitoring and medical diagnostics.
Up to one in five people on antibiotics stop taking their full course of antibiotic therapy due to diarrhea. Physicians could help patients avoid this problem by prescribing probiotics, according to a new study.

Having kids believe there’s a jolly man in a red suit who visits on Christmas Eve isn’t detrimental, although some parents can feel they’re outright lying to their children, according to a new analysis. If children attribute the same supernatural powers to Santa as they do to God, why do they stop believing in Santa, [...]
Ovarian cancer cells are “addicted” to a family of proteins produced by the notorious oncogene, MYC, and blocking these Myc proteins halts cell proliferation in the deadliest cancer of the female reproductive system.
Most atmospheric models predict that the rate of transport of air from the troposphere to the above lying stratosphere should be increasing due to climate change. Surprisingly, an international group of researchers has now found that this does not seem to be happening. On the contrary, it seems that the air air masses are moving [...]

Engineers here are developing a computerized surveillance system that, when completed, will attempt to recognize whether a person on the street is acting suspiciously or appears to be lost. Intelligent video cameras, large video screens and geo-referencing software are among the technologies that will soon be available to law enforcement and security agencies.

On the ground and in the water, researchers have been collecting imaging data on the Soufriere Hills Volcano in Montserrat to understand the internal structure of the volcano and how and when it erupts.

Researchers have discovered stem cells in the esophagus of mice that were able to grow into tissue-like structures and when placed into immune-deficient mice were able to form parts of an esophagus lining.
Ocean Acidification From Carbon Dioxide Emissions Will Cause Physiological Impairment To Jumbo Squid
The elevated carbon dioxide levels expected to be found in the world’s oceans by 2100 will likely lead to physiological impairments of jumbo squid.
Researchers have found a gene they say is inactivated in two aggressive cancers — malignant melanoma, a form of skin cancer, and glioblastoma multiforme, a lethal brain tumor. They add that because this gene, known as PTPRD, has recently been found to be inactivated in several other cancers as well, their discovery suggests that PTPRD [...]
