The amount of funds crypto projects lost to hackers has declined by about half to around $1.7 billion so far this year, amid improved security measures and an uptick in law enforcement actions.
Ukraine’s largest mobile phone operator said Russia was most likely behind a “powerful” cyberattack that disrupted phone and internet services Tuesday for about 24 million people in the country.
The cyberattack, the largest to strike Ukraine since Russia’s invasion began nearly two years ago, took down ATMs and digital banking services, disabled some air raid sirens, and hampered broader cellular service across Ukraine.
“This is definitely a cyberattack and the probability that Russian entities are behind it is very close to 100%,” Oleksandr Komarov, chief executive officer of Kyivstar GSM JSC, told Bloomberg by phone.
Scientists from the Leibniz Institute for Astrophysics Potsdam (AIP) have discovered a new plasma instability that promises to revolutionize our understanding of the origin of cosmic rays and their dynamic impact on galaxies.
At the beginning of the last century, Victor Hess discovered a new phenomenon called cosmic rays that later on earned him the Nobel prize. He conducted high-altitude balloon flights to find that the Earth’s atmosphere is not ionized by the radioactivity of the ground. Instead, he confirmed that the origin of ionization was extra-terrestrial. Subsequently, it was determined that cosmic “rays” consist of charged particles from outer space flying close to the speed of light rather than radiation. However, the name “cosmic rays” outlasted these findings.
In the new study, Dr. Mohamad Shalaby, scientists at AIP and the main author of this study, and his collaborators have performed numerical simulations to follow the trajectories of many cosmic ray particles and study how these interact with the surrounding plasma consisting of electrons and protons. The paper appears on the pre-print server arXiv.

Micrometeorites originating from icy celestial bodies in the outer Solar System may be responsible for transporting nitrogen to the near-Earth region in the early days of our solar system. That discovery was published today in Nature Astronomy by an international team of researchers, including University of Hawai’i at Manoa scientists, led by Kyoto University.
Nitrogen compounds, such as ammonium salts, are abundant in material born in regions far from the sun, but evidence of their transport to Earth’s orbital region had been poorly understood.
FDA approval for revolutionary Sickle Cell Disease gene-editing treatment promises a bright future.
Scientists have grown a tiny brain-like organoid out of human stem cells, hooked it up to a computer, and demonstrated its potential as a kind of organic machine learning chip, showing it can quickly pick up speech recognition and math predictions.
As incredible as recent advances have been in machine learning, artificial intelligence still lags way behind the human brain in some important ways. For example, the brain happily learns and adapts all day long on an energy budget of about 20 watts, where a comparably powerful artificial neural network needs about 8 million watts to achieve anything remotely comparable.
What’s more, the human brain’s neural plasticity, its ability to grow new nervous tissue and expand existing connective channels, has granted it an ability to learn from noisy, low-quality data streams, with minimal training and energy expenditure. What AI systems accomplish with brute force and massive energy, the brain achieves with an effortless elegance. It’s a credit to the billions of years of high-stakes trial and error that delivered the human brain to the state it’s in today, in which it’s chiefly used to watch vast numbers of other people dancing while we’re on the toilet.
