Solid-state sodium-ion batteries are far safer than conventional lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Researchers Friday reported developing an organic cathode that dramatically improves both stability and energy density.
Debates over gun regulations make headlines across the world, but there's an underground operation for weapons that has drawn very little attention -- until now. Researchers from Michigan State University crept into the dark web to investigate how firearms are anonymously bought and sold around the world.
Bureaucratic quality in developing countries is endangered by the structural adjustment programs imposed by the international financial institutions, a paper by Bocconi's Alexander Kentikelenis and colleagues, in the American Journal of Sociology, states. In particular, the IMF's structural reforms mandating privatization, price deregulation, and reductions in public sector employment jeopardize state capacity by compromising the healthy relationship between state and business, as in uncertain times bureaucrats are more likely to fall prey to private interests.
New evidence from Michigan State University suggests that those who smoke cannabis, or marijuana, weigh less compared to adults who don't. The findings, published in the International Journal of Epidemiology, are contrary to the belief that marijuana users who have a serious case of the munchies will ultimately gain more weight.
Lithium-ion batteries are expected to have a global market value of $47 billion by 2023, but their use in heavy-duty applications such as electric vehicles is limited due to factors such as lengthy charge and discharge cycles. UVA Engineering researchers working at Oak Ridge National Laboratory are examining how the lithium moves in battery electrodes, important in designing batteries that charge and discharge faster.
New research conducted in the Cognitive Neuroscience group of SISSA shows that a perceptual decision - recognizing an object and taking the appropriate action - is triggered as soon as the brain's processing networks accumulate the exact right quantity of sensory information. The studies uncover fundamental brain mechanisms underlying decision making in an uncertain world.
A team of scientists led by Prof. FU Chunxiang from the Qingdao Institute of Bioenergy and Bioprocess Technology completed the identification of bm5 mutant. This was the first time that the locus of maize bm5 mutant had been identified.
A KAIST research team developed a microfluidic-based drug screening chip that identifies synergistic interactions between two antibiotics in eight hours. This chip can be a cell-based drug screening platform for exploring critical pharmacological patterns of antibiotic interactions, along with potential applications in screening other cell-type agents and guidance for clinical therapies.
In situations of intimate partner violence, not knowing what will come next is sometimes a stronger predictor of a woman's health outcomes than violence frequency and severity, research at UT Health San Antonio suggests.
What will a three-degree-warmer world look like? When experiencing stress or damage from various sources, plants use chloroplast-to-nucleus communication to regulate gene expression and help them cope. Now, Salk Institute researchers have found that GUN1 -- a gene that integrates numerous chloroplast-to-nucleus retrograde signaling pathways -- also plays an important role in how proteins are made in damaged chloroplasts, which provides a new insight into how plants respond to stress.
