    China's cancer researcher Zhu Chen, together with two French researchers Anne Dejean and Hugues de Thé, received Sjoberg Prize 2018 in Stockholm Concert Hall, Sweden on Friday.

    “We used wisdom from both Chinese and Western medicine and offered a cure to one of the most deadly cancers,” Chen told Xinhua, “I feel that Chinese medicine has potential to contribute more to human health. It struggles for benefiting all mankind. It's a language of peace, and of development and progress.” Chen recalled the cooperation with the two French researchers for over 30 years.

    This year's Sjoberg winners have developed a new and targeted treatment for a specific form of blood cancer called acute promyelocytic leukaemia (急性早幼粒白血病). It was once one of the deadliest forms of cancer, but it is now possible to cure nine out of ten patients who receive the new treatment. The winners have made this revolutionary development possible by methodically mapping the molecular mechanisms responsible for the disease.

    The Prize is awarded by the Royal Swedish Academy of Sciences and is funded (资助)by the Sjoberg Foundation. The foundation, with a donation of 2.5 billion US dollars, was founded in 2016, and serves to promote scientific research that focuses on cancer, health and the environment.

    The Prize is an annual international prize in cancer research awarded to individual researchers or research groups. The prize amounts to one million US dollars, of which 100,000US dollars is the prize sum and 900,000US dollars is funding for future research.

    Driving in Canada is similar to driving in many parts of the United States. Distances and speeds, however, are posted in kilometers per hour and some signs, particularly in Quebec, may only be in French.

    Unless otherwise posted, the maximum (最大限度的) speed limit in Canada is 50km/hr in cities and 80km/hr on highways. On rural highways, the posted speed limit may be 100km/hr. It is illegal to take automobile radar detectors (汽车雷达检测器) into Quebec, Ontario, Manitoba, and the Yukon. Seat belt use is required by law for all passengers, and child car seats must be used by children under 40 pounds. Some provinces require drivers to keep their vehicles' headlights on during the day and some have banned (禁止) driving while using a hand-held cell phone. Motorcycles cannot share a lane (车道), and safety helmets for motorcycle riders and passengers are necessary. Running a red light is a serious crime throughout Canada and drivers are advised to stop before starting when a light turns green.

    Winter travel can be dangerous due to heavy snowfalls and icy conditions. Some roads and bridges are often closed in winter. Snow tires are required in some provinces. Travelers should also be careful about animals while driving at night in rural areas.

    Highway 401, from Detroit to Montreal, is one of the busiest highways in North America. It has been the scene of many deadly traffic accidents due to sudden and severe weather changes, high rates of speed, and heavy truck traffic. Thus drivers should be alert while travelling here.
