Published New insights into the timeline of mammal evolution
(via sciencedaily.com) A new study has provided the most detailed timeline of mammal evolution to date.
Published Exquisitely preserved embryo found inside fossilized dinosaur egg
(via sciencedaily.com) A 72 to 66-million-year-old embryo found inside a fossilized dinosaur egg sheds new light on the link between the behavior of modern birds and dinosaurs, according to a new study.
Published An ancient relative of Velociraptor is unearthed in Great Britain
(via sciencedaily.com) Original source A new bird-like dinosaur that used brute strength to overcome its prey has been found by palaeontologists combing through fossils found on the Isle of Wight, on the South Coast of Great Britain.
Published Sauropod dinosaurs were restricted to warmer regions of Earth
(via sciencedaily.com) Original source A study investigated the enigma of why sauropod fossils are only found at lower latitudes, while fossils of other main dinosaur types seem ubiquitously present, with many located in the polar regions.
Published Just a game? Study shows no evidence that violent video games lead to real-life violence
(via sciencedaily.com) 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?
(via sciencedaily.com) 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
(via sciencedaily.com) 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
(via sciencedaily.com) 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
(via sciencedaily.com) 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
(via sciencedaily.com) 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
(via sciencedaily.com) 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
(via sciencedaily.com) 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
(via sciencedaily.com) 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
(via sciencedaily.com) 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
(via sciencedaily.com) 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.
Published Do school-based interventions help improve reading and math in at-risk children?
(via sciencedaily.com) School-based interventions that target students with, or at risk of, academic difficulties in kindergarten to grade 6 have positive effects on reading and mathematics, according to a new article.
Published Big data tells story of diversity, migration of math's elite
(via sciencedaily.com) Research uses artificial intelligence to map connections between the world's top mathematicians.
Published Sum of cubes: New math solution for 3
(via sciencedaily.com) After cracking the 'sum of cubes' puzzle for 42, mathematicians discover a new solution for 3.
Published Laser system generates random numbers at ultrafast speeds
(via sciencedaily.com) Scientists have developed a system that can generate random numbers over a hundred times faster than current technologies, paving the way towards faster, cheaper, and more secure data encryption in today's digitally connected world.
Published The Ramanujan Machine: Researchers develop 'conjecture generator'
(via sciencedaily.com) Using AI and computer automation, researchers have developed a 'conjecture generator' that creates mathematical conjectures, which are considered to be the starting point for developing mathematical theorems.
