A natural supplement strengthened lasting anticancer immune responses in obese mice.
A new macOS information-stealing malware dubbed ClickLock terminates all visible processes to force users into entering their system login password.
The malware is designed to steal cryptocurrency assets, login credentials, password-manager data, browser information, and macOS authentication data, and it can also install a persistent backdoor for ongoing remote access to infected systems.
Researchers at Group-IB analyzed the ClickLock shell script after discovering the malware on VirusTotal, where it was first submitted on June 9. At the time of the report, it remained undetected by all security vendors available on the platform.
In a single experiment, physicists have measured the “excess” emission of high-energy gamma rays from more than a dozen heavy, unstable atomic nuclei. Mapping the gamma-ray emissions of so many isotopes produced in nuclear fission marks an important step toward a better understanding of one of the key phenomena in modern nuclear physics: the fission process itself.
Why do excited heavy nuclei produced in fission appear to emit excessive amounts of particularly energetic gamma radiation? New clues to this long-standing question have emerged from an international experiment conducted at the GANIL accelerator facility in Caen, northern France. Here, a beryllium-9 target was bombarded with uranium-238 ions, producing unstable curium-247 nuclei that rapidly underwent fission into two lighter fragments.
By combining unique experimental techniques, researchers were able—for the first time within a single experiment—to collect data on high-energy gamma-ray emissions from more than a dozen heavy, unstable isotopes. The first results of the experiment, to which the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Krakow made a significant contribution, have just been published in Physics Letters B.
