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.
New research shows that a nanometer-thin layer of water between two charged surfaces exhibits ice-like tendencies that allow it to withstand pressures of hundreds of atmospheres. The discovery could lead to better ways to minimize friction in a variety of settings.
Lucy, the most famous fossil of a human ancestor, probably died after falling from a tree, according to a new study. Researchers have found that the injury Lucy sustained was consistent with a four-part proximal humerus fracture, caused by a fall from considerable height when the conscious victim stretched out an arm in an attempt to break the fall.
Less than a week after Facebook announced that it is changing the way it handles the Trending Topics section on the social networking website, a fake article about Fox News anchor Megyn Kelly was found trending on Facebook. The article, headlined "Breaking: Fox News Exposes Traitor Megyn Kelly, Kicks Her Out for Backing Hillary" comes from a conspiracy theory website, which has more than 200,000 likes on Facebook. Its Megyn Kelly story was the topic of discussion for many across the world. The article is obviously fake. The other cited source for this trending topic was an outlet called "Conservating101"
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."
According to the study, of the older inmates, 49 percent said they experience poor or fair health, 20 percent have chronic lung disease, and 54 percent have trouble performing daily activities such as bathing, eating, using the toilet, and walking around the house. The researchers said that these rates are similar to those reported by lower income older adults who are not incarcerated.
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.
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.
Scientists report that a specialized drug screen test using lab-grown human cells has revealed two classes of compounds already in the pharmaceutical arsenal that may work against mosquito-borne Zika virus infections.
A research team has developed a continuous roll-processing technology that transfers and packages flexible large-scale integrated circuits (LSI), the key element in constructing the computer's brain such as CPU, on plastics to realize flexible electronics.
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.
To remember events in the order they occur, the brain's neurons function in a coordinated way that is akin to a symphony, a team of scientists has found. Their findings offer new insights into how we recall information and point to factors that may disrupt certain types of memories.
Researchers have developed an artificial intelligence (AI) software that reliably interprets mammograms, assisting doctors with a quick and accurate prediction of breast cancer risk. The AI computer software intuitively translates patient charts into diagnostic information at 30 times human speed and with 99 percent accuracy.
