Published Single-photon source paves the way for practical quantum encryption


Researchers describe new high-purity single-photon source that can operate at room temperature. The source is an important step toward practical applications of quantum technology, such as highly secure communication based on quantum key distribution (QKD).
Published Active video games provide alternative workout


Working out isn't known for being fun. But new active video and virtual reality games may help change that. Exergaming, or active video gaming, may be the perfect introduction to helping people be more active, according to new research.
Published Computer games in the classroom: Educational success depends on the teacher


Future teachers see educational potential in computer games, study shows. Teacher training should therefore address their potential in the classroom.
Published California's push for computer science education examined


Despite California's computer science education policies, gender, racial and ethnic disparities persist among the high schools that offer these courses, the students enrolled in them and the faculty who teach them.
Published Spatial training with blocks and puzzles could unlock the UK's mathematical potential


A sustained focus on spatial reasoning training could help children learn science, technology, engineering and mathematics.
Published Words are needed to think about numbers, study suggests


Researchers have found a new relationship between counting ability of Tsimane' individuals and their ability to perform matching tasks that involve numbers up to about 25. The results suggest that in order to think about exact numbers, people need to have a word for that number.
Published Researchers use tiny magnetic swirls to generate true random numbers


Skyrmions, tiny magnetic anomalies that arise in two-dimensional materials, can be used to generate true random numbers useful in cryptography and probabilistic computing.
Published The power of chaos: A robust and low-cost cryptosystem for the post-quantum era


Scientists develop a chaos-based stream cipher that can withstand attacks from large-scale quantum computers.
Published A new approach to a $1 million mathematical enigma


Numbers like pi, e and phi often turn up in unexpected places in science and mathematics. Pascal's triangle and the Fibonacci sequence also seem inexplicably widespread in nature. Then there's the Riemann zeta function, a deceptively straightforward function that has perplexed mathematicians since the 19th century. The most famous quandary, the Riemann hypothesis, is perhaps the greatest unsolved question in mathematics, with the Clay Mathematics Institute offering a $1 million prize for a correct proof.
Published Just a game? Study shows no evidence that violent video games lead to real-life violence


As the latest Call of Duty video game is released in the UK today, and with Battlefield 2042 and a remastered Grand Theft Auto trilogy to follow later this month, new research finds no evidence that violence increases after a new video game is released.
Published COVID-19 vaccination strategies: When is one dose better than two?


While most of the COVID-19 vaccines are designed as a two-dose regimen, some countries have prioritized vaccinating as many people as possible with a single dose before giving out an additional dose. In a new study, researchers illustrate the conditions under which a "prime first" vaccine campaign is most effective at stopping the spread of the COVID-19 virus. The team found the vaccine waning rate to be a critically important factor in the decision.
Published Using quantum Parrondo’s random walks for encryption


SUTD has set out to apply concepts from quantum Parrondo's paradox in search of a working protocol for semiclassical encryption.
Published Mathematician reveals world’s oldest example of applied geometry


A scientist has revealed that an ancient clay tablet could be the oldest and most complete example of applied geometry. The surveyor's field plan from the Old Babylon period shows that ancient mathematics was more advanced than previously thought.
Published Training helps teachers anticipate how students with learning disabilities might solve problems


Researchers found that a four-week training course made a substantial difference in helping special education teachers anticipate different ways students with learning disabilities might solve math problems.
Published Thinking in 3D improves mathematical skills


Spatial reasoning ability in small children reflects how well they will perform in mathematics later. Researchers recently came to this conclusion, making the case for better cultivation of spatial reasoning.
Published These cognitive exercises help young children boost their math skills, study shows


Young children who practice visual working memory and reasoning tasks improve their math skills more than children who focus on spatial rotation exercises, according to a large study. The findings support the notion that training spatial cognition can enhance academic performance and that when it comes to math, the type of training matters.
Published Algorithms improve how we protect our data


Scientists have developed algorithms that more efficiently measure how difficult it would be for an attacker to guess secret keys for cryptographic systems. The approach could reduce the computational complexity needed to validate encryption security.
Published Silicon could be a photonics game-changer


New research has shown that silicon could be one of the most powerful materials for photonic informational manipulation - opening up new possibilities for the production of lasers and displays.
Published Auxin makes the spirals in gerbera inflorescences follow the Fibonacci sequence


The meristem of the gerbera is patterned on the molecular level already at a stage where no primordia or other changes are discernible by even an electron microscope.
Published Basketball Mathematics scores big at inspiring kids to learn


New study with 756 1st through 5th graders demonstrates that a six-week mashup of hoops and math has a positive effect on their desire to learn more, provides them with an experience of increased self-determination and grows math confidence among youth.
