A patient's budding cortex -- in a dish? Networking neurons thrive in 3-D human 'organoid'

Science News Daily - 3 hours 29 min ago
Scientists have perfected mini cultured 3-D structures that grow and function much like the outer mantle -- the key working tissue, or cortex -- of the brain of the person from whom they were derived. Strikingly, these 'organoids' buzz with neuronal network activity. Cells talk with each other in circuits, much as they do in our brains.

Colorectal cancer genetically different in older and younger patients

Science News Daily - 4 hours 52 min ago
While the overall rate of colorectal cancer (CRC) is declining, CRC specifically among young patients is increasing. Previous studies have shown that CRC in patients younger than 50 years old tends to be more aggressive than CRC in older patients. A new study offers early evidence of genetic differences between CRC in young and old patients, possibly pointing toward different treatments and strategies in combating the young form of the disease.

Laser beam compressed into thin filament

Science News Daily - 6 hours 55 min ago
Scientists have been researching the process of laser pulse filamentation -- the effect produced when a laser beam propagating in air focuses into a filament. The researchers discovered how this process influences the preliminary transition of a beam passing through quartz glass, which has applications in the field of nonlinear optics.

'Green chemistry' to quantify the components of cosmetics

Science News Daily - 8 hours 6 min ago
There are 10,000 components that can be used to make cosmetics. These components have to be monitored to guarantee consumer safety. Scientists have now developed three 'green' analytical methods to simultaneously analyze various components used in cosmetics. In these methods very little solvent is used and very little residue is produced in comparison with other analytical techniques.

Inmates denied methadone treatment less likely to seek it once free

Science News Daily - 9 hours 40 min ago
When people on methadone maintenance treatment (MMT) are incarcerated in the United States, they are almost always forced off of the addiction-controlling medicine. In a randomized trial, inmates allowed to stay on MMT while in jail proved much more likely to seek treatment after release than those whose treatment was interrupted.
