Published Release of drugs from a supramolecular cage
(via sciencedaily.com) How can a highly effective drug be transported to the precise location in the body where it is needed? Chemists now present a solution using a molecular cage that opens through ultrasonification.
Published Focused ultrasound enables precise noninvasive therapy
(via sciencedaily.com) New research demonstrates that noninvasive neuromodulation via low-intensity ultrasound can have cell-type selectivity in manipulating neurons.
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 Using sound waves to make patterns that never repeat
(via sciencedaily.com) Mathematicians and engineers have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they say, could result in materials called 'quasicrystals' with custom magnetic or electrical properties.
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 Reading minds with ultrasound: A less-invasive technique to decode the brain's intentions
(via sciencedaily.com) A new brain imaging application uses ultrasound to predict intended movements before they happen.
Published Ultrasound has potential to damage coronaviruses, study finds
(via sciencedaily.com) A new study suggests coronaviruses, including the virus that causes COVID-19, may be vulnerable to ultrasound vibrations. Simulations suggest ultrasound waves at medical imaging frequencies can cause the virus' shell and spikes to collapse and rupture.
Published Quadruple fusion imaging via transparent ultrasound transducer
(via sciencedaily.com) Scientists have developed a quadruple fusion optical and ultrasound imaging system using a transparent ultrasound transducer.
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 Life's rich pattern: Researchers use sound to shape the future of printing
(via sciencedaily.com) Original source Researchers have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching.
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 Swimming upstream on sound waves
(via sciencedaily.com) Original source Scientists have succeeded in propelling microvehicles against a fluid flow using ultrasound. In future, these tiny vehicles are set to be introduced into the human bloodstream, thereby revolutionizing the field of medicine.
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.
Published Researchers use deep learning to identify gene regulation at single-cell level
(via sciencedaily.com) Researchers describe how they developed a deep-learning framework to observe gene regulation at the cellular level.
Published Traditional model for disease spread may not work in COVID-19
(via sciencedaily.com) A mathematical model that can help project the contagiousness and spread of infectious diseases like the seasonal flu may not be the best way to predict the continuing spread of the novel coronavirus, especially during lockdowns that alter the normal mix of the population.
Published To the brain, reading computer code is not the same as reading language
(via sciencedaily.com) Neuroscientists have found reading computer code does not rely on the regions of the brain involved in language processing. Instead, it activates the 'multiple demand network,' which is also recruited for complex cognitive tasks such as solving math problems or crossword puzzles.
