Digital wallets — like Apple Pay, Google Pay and PayPal — are projected to be used by more than 5.3 billion people by 2026. While these wallets promote increased security over traditional payment methods, reliance on outdated authentication methods and prioritizing convenience over security leaves digital wallets vulnerable, according to new research led by computer engineers at the University of Massachusetts Amherst.

$Common Food Dye Turns Skin Transparent | Podcast Imaging is central to biology and medicine, but light refracts and scatters as it hits tissues and lipids. Zihao Ou, associate professor of physics at The University of Texas at Dallas, discusses his paper demonstrating a new technique to achieve optical transparency in live tissue, a project he worked on in Guosong Hongs research group as a postdoctoral fellow at Stanford University.$

$Tougher Concrete #news #science #concrete In the construction materials used for buildings and infrastructure such as roads, strength relates to the ability to sustain weight while toughness relates to resistance to cracking. But what if there was a building material stronger and tougher than traditional materials. We’ll explore in the U.S. National Science Foundation’s “Discovery Files”. Modern society depends on the resilient materials that make up the civil infrastructure we rely on daily. Durability becomes essential in heavily used roads, buildings, and water systems. NSF-supported engineers from Princeton University have demonstrated a new technique using a cement paste in a tube-like architecture to make materials resistant to cracking and sudden failures. Inspired by the architecture of human bone and its tough outer layer, the cement-based material is 5.6 times more damage-resistant than standard counterparts. In addition to improving fracture toughness, the researchers introduced a new method to quantify the statistical degree of disorder, an important quantity for design. The researchers hope to use advanced fabrication methods such as additive manufacturing to introduce combinations of hard and soft materials into the tube structures. This new approach could further expand the possible applications while helping engineers develop new concrete components.$
