Yevhen Dykyi, Director of the National Antarctic Science Center (NASC), spoke about the challenges of maintaining the Ukrainian station in Antarctica during the war and the importance of continuing scientific research.
An eco-friendly alternative to batteries: Researchers have learned to convert Wi-Fi signal into electricity
A research team led by the National University of Singapore has made a significant step in the development of energy harvesting technology. This development could potentially eliminate the need for batteries in various electronic devices.
Why does time fly when we are busy? Scientists have revealed the secret of the brain
Scientists from the University of Nevada, Las Vegas, have found that our brains estimate time by the number of events rather than by precise units of measurement.
Polar ice melting slows down the Earth’s rotation: what does it mean?
A new study has revealed an unexpected consequence of global warming: the day on our planet is getting longer due to the melting of the polar ice. Scientists from NASA and the Swiss Federal Institute of Technology Zurich (ETH Zurich) published their findings in the journal Proceedings of the National Academy of Sciences.
Artificial intelligence can detect Parkinson’s disease with 100% accuracy 7 years before the first symptoms appear
A group of researchers has developed a blood test that uses artificial intelligence to predict Parkinson’s disease seven years before symptoms appear.
Drifting — sadistic tendencies? Researchers say that love for «loud» cars often indicates mental disorders
Psychologist Julie Aitken Shermer of the University of Western Ontario in Canada interviewed and analyzed the responses of more than 500 people to investigate the relationship between «dark» personality traits and a love of loud cars with modified mufflers.
People see with different frequencies: some people can distinguish 60 flashes per second, while others can see 35 flashes per second — study
According to a new study, some people are able to see the world at a higher «frame rate» than others. The authors believe that this trait may even give these people an advantage when it comes to competitive gaming and sports, although more research is needed to confirm this.
SCARF camera is capable of shooting at 156.3 trillion frames per second
Scientists have created an extremely fast scientific camera that captures images at an encoding rate of 156.3 THz for individual pixels, equivalent to 156.3 trillion frames per second. The research-grade SCARF (swept-coded aperture real-time femtophotography) camera could lead to a breakthrough in the study of micro-events that appear and disappear…
Breakthrough in matrix multiplication should lead to faster and more efficient AI models
Computer scientists have discovered a new way to multiply large matrices faster by eliminating a previously unknown inefficiency, leading to the largest improvement in matrix multiplication efficiency in a decade. This could eventually speed up artificial intelligence models that rely heavily on matrix multiplication.
