A Chinese network security laboratory has proposed a 24-hour online testbed, welcoming cyber attacks from any individual or organisation globally.

The permanently online and globally open testbed, which is called Network Endogens Security Testbed (NEST), would accept public tests with a total reward of 1.5 million yuan ($2,18,000), according to the Purple Mountain Laboratory for Network Communication and Security.

The Nanjing-based laboratory said Wednesday that authorised users can get corresponding bounties based on their test results, the Xinhua news agency reported.

Current network security relies on software patches or anti-virus programmes, which is like taking pills after getting ill, said Wu Jiangxing, an academician of Chinese Academy of Engineering.

As the proposer of Cyber Mimic Defence Theory, Wu said the next generation information technology should be equipped with improved “autoimmunity” in the first place.

Wu said that NEST could effectively suppress security threats caused by hidden vulnerabilities or virus Trojans without relying on external defence measures. The more it is attacked, the more protective experience it can accumulate.

NEST will provide a global public test platform for all kinds of network equipment and information systems to measure their security indicators, and offer skill training for network security practitioners, according to the laboratory.

“Whether the network is safe or not, hackers have a say. They are also welcomed to challenge it,” Wu said. (IANS)

Chinese scientists developed a combined tumor-killing therapy that can be activated specifically at tumor sites in mouse models of cancer, which is more effective than previous similar therapies.

The study published on Friday in the journal Science Immunology described the new cancer immunotherapy that can prevent the immune system from becoming tolerant of tumors, which occurs in 30 per cent of all cancer patients, the Xinhua news agency reported.

A team led by Wang Dangge from Shanghai Institute of Materia Medica under the Chinese Academy of Sciences and Fudan University developed a common immune checkpoint inhibitor in a nanoparticle formulation, which is highly tumor-specific.

The checkpoint inhibitor is a kind of increasingly popular anti-tumor drug. It can block proteins that keep immune T cells from killing cancer. But the checkpoint inhibitor used to target those immune system-suppressing proteins like PD-1 and PD-L1 often fails to reach deep-seated or metastatic tumors.

Wang’s team combined the nanoparticles carrying PD-L1-targeting antibodies with a light-activated molecule. The molecule called photosensitiser can produce tumor-killing reactive oxygen species after encountering a protein abundant in tumors, according to the study.

In mouse models, a local near-infrared radiation that activated the photosensitiser, along with the administration of antibodies-carrying nanoparticles, promoted the infiltration of cancer cell-killing T cells into the tumor site and made the tumors more sensitive to the checkpoint blockade.

This combination also helped the nanoparticles effectively suppress tumor growth and metastasis to the lung and lymph nodes, resulting in approximately 80 per cent mouse survival over 70 days, compared to complete mouse death in 45 days in the group treated with only PD-L1 antibodies, according to the study.
