Renowned mathematician Zhu Yongchang joins Tsinghua after 30 years in Hong Kong
Prominent mathematician Zhu Yongchang will join Tsinghua University in Beijing after 30 years in Hong Kong as universities in mainland China continue their efforts to recruit top-tier talent Tsinghua's Yau Mathematical Sciences Centre announced on July 9 that Zhu, previously at Hong Kong University of Science and Technology (HKUST), would join the centre in September. Zhu's research focuses on the intersection of representation theory and mathematical physics. Representation theory builds on group theory – an important branch of modern mathematics, especially algebra, that provides a basic language for modern mathematics Zhu studied mathematics at Peking University, graduating in 1984. He was part of the second cohort of students to be awarded the Shiing-Shen Chern scholarship, established to support outstanding Chinese students in pursuing further studies in the US. The scholarship was set up by mathematician Shiing-Shen Chern in collaboration with the American Mathematical Society. In 1990, Zhu obtained a doctorate in mathematics from Yale University, where he studied under mentor Igor Frenkel. Zhu was a division research fellow at the California Institute of Technology (Caltech) from 1990 to 1993, then held visiting positions at the Institute for Advanced Study at Princeton University and the Max Planck Institute in Bonn.

How to stop US bunker busters? Chinese scientists have an idea
Precision-guided bunker busters fly slowly but carry massive warheads wrapped in thick armour. Small nations without air power watch helplessly as bombs fall. Advertisement When US B-2 stealth bombers struck Iran's nuclear sites with GBU-57 MOP (Massive Ordnance Penetrator) bunker busters on June 22, there was reportedly little resistance. Chinese researchers have offered a countermeasure: strike the weak flank. Although the bomb's nose armour is thick, its steel sides are thin and measure just a few centimetres, meaning one or two anti-aircraft shells could crack it open. Low-cost anti-aircraft guns can be deployed around key sites. But the guns must survive, radar must track and electronic warfare must be countered. Instead of China's own weapon, the computer simulation used Swiss Oerlikon GDF guns which are widely fielded in the Middle East , including Iran. Advertisement The GDF fires 36 shells in two seconds. At 1,200 metres (0.7 miles), the kill probability hits 42 per cent.

Chinese scientists develop low-cost cell therapy for cancer, asthma, autoimmune diseases
Chinese researchers have come up with a cheaper and easier way of delivering a highly specialised, personalised cell therapy to treat blood cancers and other serious diseases. This new method is much easier to programme than the conventional approach and is available at a fraction of the cost, according to experts in the field. The treatment, known as CAR-T, is a type of immunotherapy that has taken off in recent years and has also shown promise in treating other conditions such as asthma and autoimmune diseases. However, these cell therapies are difficult to produce and deliver to patients, and they are expensive A group of Chinese medical experts has now proposed a solution to these drawbacks, using gene therapy tools. They reported that they had managed to produce anticancer cells directly inside the human body and, for the first time, had used them to treat four patients with multiple myeloma – the second most common form of blood cancer. Currently, the cost of a single treatment is estimated to exceed one million yuan (US$139,200). The study, led by researchers from the Institute of Haematology at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology in Wuhan, was published in the peer-reviewed journal The Lancet earlier this month.
