Phys.org / A physicist's fresh look at the 'prisoner's dilemma' reveals hope for cooperation
The "prisoner's dilemma" is one of the most famous ideas in game theory. For decades, this game has been used to explain why selfishness often beats cooperation. In the prisoner's dilemma, two players can either cooperate ...
Phys.org / Overlooked 'history force' may skew particle motion by up to 60% in shaken fluids
Physicists at the University of Bayreuth have investigated the so-called Basset–Boussinesq history force acting on particles in fluids. Due to the difficulty of calculating it, this force is often neglected—a fact that Bayreuth ...
Phys.org / India issues heat wave warnings as fear of El Nino looms
India's weather agency warned on Wednesday of the risk of upcoming "extreme" heat made worse by the potentially powerful El Niño weather pattern, issuing heat wave preparedness guidelines as temperatures soared.
Phys.org / TriPcides target MRSA, suppress infection and kill dormant bacteria to open a new front against antibiotic resistance
In a new study, researchers show how so‑called TriPcides can target the bacterium Staphylococcus aureus, including antibiotic‑resistant strains such as MRSA. The compounds disrupt the bacteria's ability to cause infection ...
Phys.org / Bioengineers condense protein engineering and testing to a single day
Proteins are critical to life—and to industry. There are countless proteins that could be engineered to treat and even cure serious diseases and cellular dysfunctions. Industrial applications are similarly promising, with ...
Phys.org / New shell helps gold nanoparticles keep shape under laser heat longer
Gold nanoparticles, which are about one-thousandth the width of a human hair, can convert light they receive from a laser into heat. This capacity, known in medicine as photothermal therapy, is effective at destroying cancer ...
Phys.org / A SpaceX rocket will soon hit the moon, raising concerns about handing over space launches to private companies
SpaceX seems to have mistaken shooting for the moon with shooting at the moon. Forecast to occur on Aug. 5, a five-story-long piece of a rocket from one of the private space exploration company's recent lunar missions is ...
Tech Xplore / Solar power leaves land behind as floating systems gain ground
The effects of global warming are becoming increasingly evident and catastrophic. To prevent irreversible consequences, international scientific consensus emphasizes the importance of mitigating climate change in ways that ...
Tech Xplore / When AI imagines cities, smaller communities can disappear
When College of Natural Resources and Environment geospatial data scientist Junghwan Kim asked an artificial intelligence (AI) image generator to create a picture of Blacksburg, the result wasn't quite right. "The image looked ...
Tech Xplore / Custom device maps carbon capture reactions in real time
Removing carbon dioxide (CO2) directly from the air, a process called direct air capture (or DAC), is one of several approaches being developed to help reduce the concentration of this greenhouse gas in the atmosphere. Among ...
Medical Xpress / Why does ALS pathology spread differently among patients?
A research team at the Brain Research Institute, Niigata University has found that APOE ε4, a genetic factor best known for increasing the risk of Alzheimer's disease, may also influence how pathological changes spread in ...
Medical Xpress / Vitamin C may help prevent cancer, according to study of dietary patterns and water quality
A new study from the University of Waterloo uses mathematical modeling to examine how Vitamin C affects chemical reactions in the digestive system that are linked to cancer development. Over the last several decades, North ...
