Research on social cognition reveals that implicit attitudes play a crucial role in shaping stereotypical beliefs about social groups. The study found that individuals' automatic positive-negative judgments supersede specific group traits or stereotypes.
Researchers at Georgia Tech and Multiscale Systems Inc. used percolation theory to model how a large-scale hack on Internet-connected cars would affect traffic in Manhattan. A small-scale hack affecting only 10% of vehicles could cause citywide gridlock, while using multiple networks for connected vehicles decreases the risk.
The new quantum sensor developed by researchers at the University of Waterloo promises significant advancements in long-range 3D imaging and monitoring the success of cancer treatments. The sensors can detect single particles of light with high timing resolution, speed, and efficiency over an unparalleled wavelength range.
Recent widespread fires in California suggest a shift in climate-fire relationships, where increased temperatures and drier summers will override the dynamical influence of the North Pacific Jet. The researchers reconstructed over 400 years of North Pacific Jet variability, finding that fire suppression may be responsible for this change.
Researchers at IBS have identified the mistake-rate of DNA editing tools using CRISPR and adenine base editors. The study reveals that ABE7.10, a widely used gene engineering tool, has an average of 60 off-target mistakes in the human genome.
Researchers discovered thousands of tiny 'ice quakes' on the McMurdo Ice Shelf that appear to be caused by pools of partially melted ice expanding and freezing at night. This phenomenon may help track glacier melting and explain the breakup of large ice shelves.
Researchers have developed a new vaccine strategy for tuberculosis that protects against the disease by delivering a vaccine directly into the lungs through a spray. The new formulation shows promise in mice studies, with significantly reduced lung inflammation and tissue damage compared to current vaccines.
Scientists have created a 3D printable sensor that can detect tiny amounts of water, changing color from purple to blue in wet conditions. The sensor is made of a cheap, flexible, and non-toxic copper-based compound that can be printed into various shapes.
A global team predicts that by 2050, 49% of the world's population will live in areas where Aedes aegypti and Aedes albopictus mosquitoes are established. Climate change and human migration patterns drive the spread of these disease-carrying insects.
Purdue researchers have successfully probed interference of quasiparticles using a new device. The device, built with molecular beam epitaxy, overcomes technical challenges to observe quantum mechanical effects. This breakthrough may be key to developing topological qubits and advancing quantum computing.
A team of neuroscientists found that the brain's pathways play a crucial role in shaping speech rhythms, with some people synchronizing their speech to match external rhythms while others do not. High synchronizers have more white matter volume in key brain pathways and better language learning abilities than low synchronizers.
