1. China commissions new Type 055 destroyer

The People's Liberation Army (PLA) Navy recently commissioned its second Type 055 guided-missile destroyer, naming it Lhasa, after the capital of the Tibet autonomous region.

Developed and built by China State Shipbuilding Corp, the Type 055 is the country's newest class of guided-missile destroyer. It has a displacement of more than 12,000 metric tons and is equipped with new types of air-defense, missile-defense, anti-ship and anti-submarine weapons.

The entry of the vessel into service marks a milestone in the PLA Navy's strategic transformation effort, and will substantially improve the Navy's long-range operational capabilities as well as its carrier battle groups' combat strength.

2. Chinese scientists achieve single photon 3D imaging over 200 km

Scientists from the University of Science and Technology of China (USTC) recently achieved the three-dimensional imaging of single photons from a distance of more than 200 kilometers; the first achievement of its kind in the world.

It can be applied in fields like remote target recognition and earth observation.

3. New findings may contribute to anemia treatment

A medical research paper published in Nature Immunology on March 23 showed that interleukin-22 (IL-22), a signal transduction molecule in the immune system, has been proved to inhibit the production of red blood cells and make mice anemic.

It is the first time that an immune signal transduction molecule has been found to inhibit the production of red blood cells. The result may provide an insight into the treatment of stress-induced anemia in human patients.

4. China develops world's most advanced proton therapy system accelerator

According to the Hefei Institute of Physical Science at the Chinese Academy of Sciences (CAS), the self-developed superconducting cyclotron proton therapy system accelerator has successfully extracted a 200 MeV (mega electron volts) stable proton beam from the treatment room.

It means that the world's most compact superconducting cyclotron proton therapy system has been developed in China.

5. Another vaccine approved for emergency use in China

The recombinant protein subunit COVID-19 vaccine, which has been jointly developed by the CAS Institute of Microbiology and Anhui Zhifei Longcom Biopharmaceutical, was recently approved by the National Medical Products Administration.

It is the fourth vaccine to be given emergency use approval in China, three of which have since been approved for conditional market use.
