There is a vicious cycle of vanity on social media, according to new results
. College-age women who viewed positive feedback on Instagram selfies then experienced greater body dissatisfaction - because they put more focus on appearance and in the end fueled body dissatisfaction among viewers.
A new photoelectrode can harvest 85 percent of visible light in a 30 nanometers-thin semiconductor layer between gold layers, converting light energy 11 times more efficiently than previous methods, another step on the road to turning solar power from an expensive subsidized sideshow into the default energy of the future.
The famous paradox 'which came first, the chicken or the egg?' was created by philosophers to discuss cause and effect. Since chickens lay eggs, and eggs produce chickens...you get the idea.
A new paper declares that whole grains can help prevent type 2 diabetes but a quick glance at the methodology will show you why you need to be skeptical. It doesn't matter if it’s rye, oats, wheat, wheatberries, bulgur, or couscous, any whole grain will do. Which is like declaring that any pasta can reduce type 2 diabetes, which will also be true - if in either case the calories are reduced.
Type 2 diabetes, which unlike Type 1 does not involve an inability to produce insulin but rather involves insulin production being overworked, is overwhelmingly related to obesity. That is why unlike Type 1 it is more of an adult disease. To prevent it requires more than using a type of food, it involves consuming less of all foods.
Though sexual assault and dating violence in the academic and cultural world focuses most heavily on men, among teens there are more Asia Argento's than Twitter recognizes.In recent findings
, 5.8 percent of boys and 4.2 percent of girls said they had experienced dating violence in the past year. The good news is that dating violence among teens has declined overall, from 6 percent of teens reporting dating violence in 2003 down to 5 percent in 2013.
A fully 3D printed array of light receptors on a hemispherical surface is the first significant step toward creating a "bionic eye."The project
began with a hemispherical glass dome to show how they could overcome the challenge of printing electronics on a curved surface. Using a custom-built 3D printer, they started with a base ink of silver particles. The dispensed ink stayed in place and dried uniformly instead of running down the curved surface. The researchers then used semiconducting polymer materials to print photodiodes, which convert light into electricity. The entire process took about an hour.
