Published Better cybersecurity with new material
(via sciencedaily.com) Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.
Published Effectiveness of video gameplay restrictions questioned in new study
(via sciencedaily.com) Legal restrictions placed on the amount of time young people in China can play video games may be less effective than originally thought, a new study has revealed.
Published Social media algorithms exploit how humans learn from their peers
(via sciencedaily.com) In prehistoric societies, humans tended to learn from members of our ingroup or from more prestigious individuals, as this information was more likely to be reliable and result in group success. However, with the advent of diverse and complex modern communities -- and especially in social media -- these biases become less effective. For example, a person we are connected to online might not necessarily be trustworthy, and people can easily feign prestige on social media. Now, a group of social scientists describe how the functions of social media algorithms are misaligned with human social instincts meant to foster cooperation, which can lead to large-scale polarization and misinformation.
Published Scientists uncover a surprising connection between number theory and evolutionary genetics
(via sciencedaily.com) An interdisciplinary team of mathematicians, engineers, physicists, and medical scientists has uncovered an unexpected link between pure mathematics and genetics, that reveals key insights into the structure of neutral mutations and the evolution of organisms.
Published Engineering team uses diamond microparticles to create high security anti-counterfeit labels
(via sciencedaily.com) Original source Researchers have developed a pioneering technological solution that counterfeiters have no response to.
Published Researchers visualize activity of CRISPR genetic scissors
(via sciencedaily.com) Original source Scientists have developed a new method to measure the smallest twists and torques of molecules within milliseconds. The method makes it possible to track the gene recognition of CRISPR-Cas protein complexes, also known as 'genetic scissors', in real time and with the highest resolution. With the data obtained, the recognition process can be accurately characterized and modeled to improve the precision of the genetic scissors.
Published Board games are boosting math ability in young children
(via sciencedaily.com) Board games based on numbers, like Monopoly, Othello and Chutes and Ladders, make young children better at math, according to a comprehensive review of research published on the topic over the last 23 years.
Published How the brain processes numbers -- New procedure improves measurement of human brain activity
(via sciencedaily.com) Original source Measuring human brain activity down to the cellular level: until now, this has been possible only to a limited extent. With a new approach it will now be much easier. The method relies on microelectrodes along with the support of brain tumor patients, who participate in studies while undergoing 'awake' brain surgery. This enabled the team to identify how our brain processes numbers.
Published Mathematicians solve long-known problem
(via sciencedaily.com) Original source Making history with 42 digits: Scientists have unlocked a decades-old mystery of mathematics with the so-called ninth Dedekind number. Experts worldwide have been searching for the value since 1991. Scientists arrived at the exact sequence of numbers with the help of the Noctua supercomputer.
Published QuanÂtum comÂputer in reverse gear
(via sciencedaily.com) Original source Large numbers can only be factorized with a great deal of computational effort. Physicists are now providing a blueprint for a new type of quantum computer to solve the factorization problem, which is a cornerstone of modern cryptography.
Published Researchers explore why some people get motion sick playing VR games while others don't
(via sciencedaily.com) Original source The way our senses adjust while playing high-intensity virtual reality games plays a critical role in understanding why some people experience severe cybersickness and others don't.
Published Can investigators use household dust as a forensic tool?
(via sciencedaily.com) Original source It is possible to retrieve forensically relevant information from human DNA in household dust.
Published New research suggests peer-advisor relationship is key to success
(via sciencedaily.com) Collaborative research across the country has shown that strengthening the relationship between the student and advisor can increase retention rates in engineering doctoral studies.
Published Study highlights complicated relationship between AI and law enforcement
(via sciencedaily.com) A recent study that examined the relationship between artificial intelligence (AI) and law enforcement underscores both the need for law enforcement agencies to be involved in the development of public policies regarding AI -- such as regulations governing autonomous vehicles -- and the need for law enforcement officers to better understand the limitations and ethical challenges of AI technologies.
Published Scholars unify color systems using prime numbers
(via sciencedaily.com) Existing color systems, such as RGB and CYMK, are all text-based and require a large range of values to represent different colors, making them difficult to compute and time-consuming to convert. Recently, researchers made a breakthrough by inventing an innovative color system, called 'C235', based on prime numbers, enabling efficient encoding and effective color compression. It can unify existing color systems and has the potential to be applied in various applications, like designing an energy-saving LCD system and colorizing DNA codons.
Published Chromo-encryption method encodes secrets with color
(via sciencedaily.com) In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.
Published Video game playing causes no harm to young children's cognitive abilities, study finds
(via sciencedaily.com) Despite old fears that bad effects follow excessive video game playing or questionable game choices, researchers found those factors mattered little, if any, in children's brain health. The bad news? Video games assumed to be effective learning tools showed no meaningful effects, either.
Published New DNA biosensor could unlock powerful, low-cost clinical diagnostics
(via sciencedaily.com) By flagging disease-associated DNA biomarkers, medical professionals can make early diagnoses and provide personalized treatments, but the typical screening methods can be laborious, expensive or limited in scope. Now, a new biosensor could pave the way to accessible and expansive diagnostics.
