China is exploring the potential of artificial intelligence (AI) in improving their government operations and services. J. Ramon Gil-Garcia and Yi Long of the Shanghai University of Political Science and Law have analyzed the AI processes currently utilized in China to manage government services, and whether other forms of automation could be better options for ensuring transparency. The authors suggest considering hybrid approaches, proposing a classification of services by considering the extent of automation and process transparency needed.

The ATLAS collaboration has achieved the most precise measurement to date of the Higgs boson's mass, with a precision of 0.11%. This result is attributed to advanced calibration techniques and powerful reconstruction algorithms, and has been made with the full ATLAS Run 2 data set. This finding is crucial for understanding the universe's fundamental structure, and will allow for the more precise testing of the Standard Model.

The US Navy has developled a new mini-submersible for covert operations called the Dry Combat Submersible (DCS) which is significantly different from the other submersibles currently used by the Navy. This new submersible is capable of diving, travelling and carrying personnel much further than before whilst also being much drier and safer. The DCS will have a wide range of uses for US Navy SEALs and could potentially transform the way special ops forces operate in the future.

Shein and Temu, two Chinese e-commerce platforms occupy the same off-price shopping space and are engaged in an escalating legal battle over what each claims is unfair competition. Shein accused Temu of misleading consumers into thinking they were the same company while Temu claims that Shein is coercing manufacturers into arrangements that force them to not do business with Temu. There is also a long history of exclusivity agreements in Chinese tech fights with companies like Meituan and Alibaba’s Tmall enforcing them. Now a new tactic has emerged with the Shein–Temu battle- trademark bullying.

The US has over 50,000 reservoirs used for water supply, drought relief, and flood protection. During extreme storms, reservoir managers must make difficult decisions about how to use the reservoir to balance releasing water to avoid flooding downstream and limiting water to help downstream communities. Improving forecasting could reduce flood damage.

In a recent breakthrough, a POSTECH research team proposed a novel method for optimal sampling of data stored across various tables. This new technique called degree-based rejection sampling (DRS) managed to generate results rapidly with the help of techniques like generalized hypertree decompositions (GHDs). The acceptance of DRS and GHDs drastically reduces the time needed to join tables and acquire data for advanced AI applications.

Scientists recently made an accidental discovery that some metals are able to heal themselves. This self-healing process is caused by a combination of local stress and grain boundary migration and can be observed at the nanoscale level. The research made could pave the way for future applications of self-healing metal into various structures, potentially improving their resistance and durability over time.

Fossil bones have revealed new Jurassic-era dinosaur species named Oblitosaurus bunnueli. It is believed to be the basalmost member of the Ankylopollexia, estimated to have measured 6-7m in length and is likely to be the trackmaker of large ornithopod tracks found in the Upper Jurassic of the Iberian Peninsula.

MIT researchers have created a tool called PhotoGuard which prevents AI image manipulation. It does so by encoding images with imperceptible secret signals that alter how the AI model interprets them, or by disrupting the way the models generate images. This tool can be used to protect against malicious AI image manipulation, such as nonconsensual deepfake pornography.

Rip currents are powerful currents that flow from shore to sea at speeds of up to several feet per second, making them dangerous to beach-goers. There are two types of rip currents, bathymetric and transient, which are created by wave action. To stay safe, avoid beaches with lifeguards, pay attention to beach flags, and follow escape techniques such as floating and swimming parallel to the shore.

Water vapor molecules have been discovered for the first time in a rocky planet-forming zone of a star system 370 light-years away from Earth. Significantly, the James Webb Space telescope identified the molecular signature in the region with the potential to develop Earth-like planets. The notable finding of extraterrestrial water offers clues about the formation of Earth and its vast water reservoirs. Current efforts to uncover further details focus on the origin of the water and its ability to retain existence close to the star within the inner disk.
