(via sciencedaily.com) Original source Video gamers who exploit glitches in games can help experts better understand buggy software, students suggest.
Published The math problem that took nearly a century to solve: Secret to Ramsey numbers
(via sciencedaily.com) Original source Little progress had been made in solving Ramsey problems since the 1930s. Now, researchers have found the answer to r(4,t), a longstanding Ramsey problem that has perplexed the math world for decades.
Published Where quantum computers can score
(via sciencedaily.com) Original source The traveling salesman problem is considered a prime example of a combinatorial optimization problem. Now a team has shown that a certain class of such problems can actually be solved better and much faster with quantum computers than with conventional methods.
Published Satellites for quantum communications
(via sciencedaily.com) Original source Through steady advances in the development of quantum computers and their ever-improving performance, it will be possible in the future to crack our current encryption processes. To address this challenge, researchers are developing encryption methods that will apply physical laws to prevent the interception of messages. To safeguard communications over long distances, the QUICK space mission will deploy satellites.
Published Swarming cicadas, stock traders, and the wisdom of the crowd
(via sciencedaily.com) Original source The springtime emergence of vast swarms of cicadas can be explained by a mathematical model of collective decision-making with similarities to models describing stock market crashes.
Published Giving video games this Christmas? New research underlines need to be aware of loot box risks
(via sciencedaily.com) Original source At-risk individuals, such as those with known gaming and gambling problems, are more likely to engage with loot boxes than those without. The study is the result of one of the largest, most complex and robustly designed surveys yet conducted on loot boxes, and has prompted experts to reiterate the call for stricter enforcement around them.
Published Keep it secret: Cloud data storage security approach taps quantum physics
(via sciencedaily.com) Original source Distributed cloud storage is a hot topic for security researchers, and a team is now merging quantum physics with mature cryptography and storage techniques to achieve a cost-effective cloud storage solution.
Published Certain online games use dark designs to collect player data
(via sciencedaily.com) Original source The privacy policies and practices of online games contain dark design patterns which could be deceptive, misleading, or coercive to users, according to a new study.
Published Machine learning unravels mysteries of atomic shapes
(via sciencedaily.com) New research has used machine learning to find the properties of atomic pieces of geometry, in pioneering work that could drive the development of new results in mathematics.
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 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
