Use it or lose it: Stopping exercise decreases brain blood flow

Science Daily - Mon, 29/08/2016 - 6:04pm
Researchers examined cerebral blood flow in master athletes (ages 50-80 years) before and after a 10-day period during which they stopped all exercise. Using MRI brain imaging techniques, they found a significant decrease in blood flow to several brain regions important for cognitive health, including the hippocampus, after they stopped their exercise routines.

Apple Is Making Life Terrible In Its Factories

Slashdot - Mon, 29/08/2016 - 4:50pm
An anonymous reader writes: Pressure from Apple to lower costs is driving worsening conditions for workers at the company's manufacturing partners.This according to watchdog group China Labor Watch, which says that under CEO Tim Cook, the Cupertino giant has asked the companies that assemble its products to cut their own costs, and those demands have led them to cut back on worker pay and factory conditions. Specifically, the group reports that Pegatron has been passing on financial pressures from Apple by committing multiple violations of Chinese labor laws on fair pay and workplace safety."Working conditions are terrible, and workers are subject to terrible treatment," China Labor Watch writes. "Currently, Apple's profits are declining, and the effects of this decline have been passed on to suppliers. To mitigate the impact, Pegatron has taken some covert measures to exploit workers."

Alzheimer's: Nicotinic receptors as a new therapeutic target

Science Daily - Mon, 29/08/2016 - 4:31pm
Studies have indicated that nicotine may be beneficial for memory function. Scientists are set out to shed further light on the properties attributed to nicotine by determining the precise structure of the nicotinic receptors in the hippocampus region of the brain. Using mouse models for Alzheimer's disease, they identified the a subunit of the nicotinic receptor as a target that, if blocked, prevents the memory loss associated with Alzheimer's.

Outpatient bloodstream infections costly for pediatric transplant and cancer patients

Science Daily - Mon, 29/08/2016 - 4:31pm
Pediatric stem cell transplant and cancer patients often are discharged from the hospital with an external central venous line for medications that parents or other caregivers must clean and flush daily to avoid potentially life-threatening infections. If an outpatient develops a bloodstream infection associated with the central line, median charges to treat it total $37,000 for a six-day hospital stay for young patients whose disease treatments have weakened their immune systems and infection-fighting abilities.

Amazon forests: Biodiversity can help mitigate climate risks

Science Daily - Mon, 29/08/2016 - 4:22pm
A forest with greater diversity of plants can better adjust to climatic stress. Now for the first time, a team of scientists can show this in computer simulations of the Amazon region by accounting for its amazing diversity of trees. Biodiversity can hence be an effective means to mitigate climate risks and should not only be seen in the context of nature conservation.
