Dr Jian Zhou was a molecular biologist and virologist who worked with Professor Ian Frazer to develop the technology toward the Gardasil and Cervarix vaccines (疫苗),     1     protect against viruses that cause cervical cancer.

Born in Hangzhou, China, Dr Zhou graduated from Wenzhou Medical College and went on     2     (obtain) a Master’s degree from Zhejiang Medical University. He studied for a PhD at Henan Medical University,     3     (complete) this in 1987. He received a Doctor of Medicine from the University of Queensland in 1994. Dr Zhou’s interest in human papillomavirus (HPV)     4     (bring) him to Australia in 1990 to join Professor Ian Frazer’s Centre for Immunology and Cancer Research at the University of Queensland. Nearly all cervical cancers are caused by HPV and it     5     (believe) that a vaccine against HPV might work. The vaccine required a particle that would stimulate an immune response to the virus,     6     causing an infection. This was a significant focus of Dr Zhou’s work with Professor Frazer and in 1990, working also with his wife, he succeeded in creating a virus-like particle that was now the basis     7     the Gardasil and Cervarix vaccines.

    8     (unfortunate), Dr Zhou died in 1999, at the age of 42. His work has had     9     huge impact on human health globally. The Australian Academy of Health and Medical Sciences is therefore delighted to establish an award in     10     (recognize) of Dr Zhou. The Jian Zhou Medal was made possible by a generous donation from the Frazer Family Foundation.

2 . Scientists from Tufts University have developed tiny groups of human cells that can move on their own-and in a lab experiment, these so-called “anthrobots” inspired sheets of human neurons to repair themselves when damaged. The researchers hope the collections of cells could one day be used to treat diseases or aid with healing in humans.

The study comes on the heels of earlier work from one of its authors, who produced tiny robots by stitching together frog embryo cells. These robots, known as “xenobots”, could assemble themselves, move across surfaces and travel through liquid.

Since they're not made from human cells, xenobots can't be used to treat humans, writes Matthew Hutson, a freelance science writer. But the anthrobots in the new study could theoretically. Each anthrobot started with a single cell from an adult human lung. It then grew into a multicellular biobot after being cultured (培养) for two weeks.

These lung cells are covered in cilia. But at this point in the research, the cilia were growing inside the clumps of cells. So, for the next week, the researchers grew the cells in a solution (溶液) that caused the cilia to face outward instead, enabling these structures to move the anthrobots, which could move in tight loops, travel in straight lines or wiggle in place. Their speed varied as well.

The researchers also tested how these robots might heal wounds. They mimicked (模拟) a wound by scratching a layer of neurons in a dish. Then, they introduced anthrobots to the site of the scratch, and within days, the neurons regrew, bridging the gap created by the wound. The findings show new structures that might have uses in biomedical settings can be developed without gene editing and without having to design the structures manually, the study authors write.

“Unlike xenobots, anthrobots don't require tools to give them shape, and we can use adult cells-even cells from elderly patients-instead of embryonic cells,” says Gizem Gumuskaya, the paper's lead author. "We can produce these robots in large amounts in parallel, which is a good start for developing a therapeutic tool.”

An increasing number of people in China and abroad are discovering or rediscovering the benefits of moxibustion (艾灸),     1     traditional Chinese medicine (TCM) treatment used since about 500 BC. The treatment     2     (aim) at removing cold and dampness from the body, strengthening the blood, increasing the flow of qi or energy     3     (channel) and maintaining general well-being.

Mugwort, a flowering plant, is the key     4     moxibustion. Mugwort leaves are dried and ground into small sticks or cones called moxa (灼烙剂), which are then lighted and used     5     (warm) points on your body and relieve the symptoms.

There are two methods of moxibustion treatment. One is called the direct treatment     6     a small and burning cone-shaped moxa is placed on the patient’s treated acupoint (穴位). In the indirect treatment, the burning moxa doesn’t directly touch your body. This treatment is much     7     (safe) and can be used on a larger area, such as muscle groups. It is also the     8     (prefer) cure for children.

Moxibustion treatment can be used for a wider variety of medical conditions. But TCM fans consider the cure to be     9     (extreme) effective in treating arthritic conditions, especially joint pains when the conditions     10     (worse) in cold or damp weather.

5 . Britain is launching the world’s largest ever clinical trial of the Galleri test, which picks up pieces of genetic code from DNA before symptoms such as lumps (肿块) appear. The test is a game-changer for early cancer detection, which can detect more than 50 types of the disease in the very early stages. It has been developed by GRAIL, a healthcare company focusing on early cancer detection.

National Health Service (NHS) chief executive Amanda Pritchard said, “This quick and simple blood test could mark the beginning of a revolution in cancer detection and treatment here and around the world. By finding cancer before signs and symptoms appear, we have the best chance of treating it and we can give people the best chance of survival.

NHS has sent out invites across the country offering the test to 140,000 people aged 50 to 77 with no cancer symptoms. Another 6,000 with suspected signs have been offered to speed up their diagnosis (诊断). Blood samples will be taken at mobile clinics in retail parks and community locations. Laboratory analysis produces a result in a fortnight. Each test costs € 620 but NHS has negotiated a discounted price. Half the participants will have their blood screened with the Galleri test right away and samples from the rest will be stored and tested in the future. This will allow scientists to compare the stage at which any tumours (肿瘤) are detected between the two groups.

“The Galleri test can not only detect a wide range of cancer types but can also predict where the cancer is in the body with a high degree of accuracy. Earlier trial results showed it can detect 68% of 12 deadly cancers,” Health Secretary Sajid Javid said. In England 56% of cancers are diagnosed at stage one or two. NHS aims to increase that to three quarters by 2028. If found early there are a broader range of treatment options available, which can be curative and are often less aggressive.
