China s deep-sea drilling system Sea Bull IIbored a core of 231 meters more than 2,000 meters beneath the surface in the South China sea at around 11 pm Wednesday, setting a new world record.
Sea Bull II, a project of China s National Key R&D Program, is also the country s first deep-sea drill with a depth of more than 100 meters with a pressure coring function.
Promising protocol much easier to fingerprint than HTTPS Share

Google s QUIC (Quick UDP Internet Connections) protocol, announced in 2013 as a way to make the web faster, waited seven years before being implemented in the ad giant s Chrome browser. But it still arrived before privacy could get there.
A trio of researchers from China have found that QUIC is more vulnerable to web fingerprinting than HTTPS, a shortcoming that could make it easier for an adversary to infer which websites an individual is visiting by scrutinizing network traffic.
Boffins Pengwei Zhan and Liming Wang of the Chinese Academy of Sciences, and Yi Tang, of Guangzhou University, funded by China’s National Key R&D Program, describe their findings in a paper distributed via ArXiv.

A Chinese research team has recently disclosed the transmission mechanism of novel coronavirus (SARS-CoV-2) in minks and found that vaccination is a potential strategy to prevent minks from transmitting the virus.
The research team from Harbin Veterinary Research Institute under the Chinese Academy of Agricultural Sciences (CAAS), published their paper Replication, pathogenicity, and transmission of SARS-CoV-2 in minks in the National Science Review on Dec. 8. The National Science Review is an open access journal reporting cutting-edge scientific and technological developments in China and around the world under the auspices of the Chinese Academy of Sciences (CAS).
Researchers found that SARS-CoV-2 replicates efficiently in both the upper and lower respiratory tracts and causes severe lesions in the nasal mucosa and lungs of minks. The pulmonary lesions are highly similar to those seen in human COVID-19 patients. The study also showed that SARS-CoV-2 transmit
