- Social circles: Degree to which urban movement is linked to social activity
If you live in a city, you know that a fair amount of your movement around town is social in nature. But how much, exactly? A study uses a new method to infer that around one-fifth of urban movement is strictly social, a finding that holds up consistently in multiple cities.
- Caging of molecules allows investigation of equilibrium thermodynamics
High performance materials for gas storage, thermal insulators or nanomachines need a thorough understanding of the behavior of the material down to the molecular level. Thermodynamics, which have been developed two hundred years ago to increase the efficiency of steam engines, typically observes and averages over a large number of molecules. Now a team of scientists has developed a methodology, to investigate the equilibrium thermodynamics of single molecules.
- Type 2 diabetes, fatty liver disease reversed in rats
A controlled-release oral therapy has been developed by scientists that reversed type 2 diabetes and fatty liver disease in rats, according to a study. "Given these promising results in animal models of NAFLD/NASH and type 2 diabetes we are pursuing additional preclinical safety studies to take this mitochondrial protonophore approach to the clinic" said the researchers.
- Minipool technology to prepare immunoglobulins to fight viral infections in d...
Researchers have described a new, pragmatic, method for the production of immunoglobulin G from human plasma in developing countries.
- African Americans who fled the South during great migration led shorter lives
Millions of African Americans moved from the South in the early 20th century to seek better job opportunities and higher wages, but a new study on the historic Great Migration shows that with improved economic conditions came a greater risk of mortality.
- Asian Herb Holds Promise as Treatment for Ebola Virus Disease
New research focuses on the mechanism by which Ebola virus infects a cell and the discovery of a promising drug therapy candidate. A small molecule called Tetrandrine derived from an Asian herb has shown to be a potent small molecule inhibiting infection of human white blood cells in vitro or petri dish experiments and prevented Ebola virus disease in mice.
- Traditional forms of media coverage valued over advertising
In an age where digital media is constantly changing, public relations practitioners and business professionals still see the benefits of traditional media coverage, according to a recent study.
- How mantis shrimp evolved many shapes with same powerful punch
The miniweight boxing title of the animal world belongs to the mantis shrimp, a cigar-sized crustacean whose front claws can deliver an explosive 60-mile-per-hour blow akin to a bullet leaving the barrel of a gun. A study of 80 million years of mantis shrimp evolution reveals how these fast weapons evolved their dizzying array of shapes -- from spiny and barbed spears to hatchets and hammers -- while still managing to pack their characteristic punch.
- Method for mapping neuron clusters developed
A method for identifying clusters of neurons that work in concert to guide the behavior has been developed by researchers. Their findings address a long-standing mystery about the organization of the prefrontal cortex (PFC) -- one of the most recently evolved parts of the primate brain that underlies complex cognitive functions.
- GLP-1 secretion is reduced in overweight, pre-diabetes and type 2 diabetes
The world's largest study looking at the secretion of the gut hormone GLP-1 has found that the secretion is reduced among overweight and obese people, people with pre-diabetes and newly diagnosed people with type 2 diabetes.
