>3D-printed tantalum implant
China has performed clinical trials on its homegrown 3D-printed porous tantalum implants, taking a leading position globally in this technology.
The research project into customized 3D-printed porous tantalum implants began in 2016.
The research team, led by the First Hospital Affiliated to Army Medical University (AMU), completed the world's first knee-revision surgery using a customized 3D-printed porous tantalum implant in 2017 and has so far conducted 27 clinical trials on tantalum implants.
The incidence of osteoarthritis among Chinese is about 2.2-3.5%, and the rate has increased to 27% and 62% among people aged 40-49 and 50-59, respectively, according to Yang Liu, head of the department of joint surgery at the First Hospital Affiliated to AMU.
Customized 3D-printed implants can fill and reconstruct bone defects, better helping patients to recover and reducing side effects.
>'Reef-toxic' sunscreen ban
Palau has become the first country in the world to ban sun cream which damages coral reefs and other sea life.
The Pacific island country, which is in the Western Pacific ocean near the Philippines, is one of the most popular diving destinations in the world.
It has banned sun cream which contains common components such as oxybenzone from being either applied or sold in shops.
Tourists will have the forbidden suncream seized when entering Palau and shops which sell it could be hit with fines of up to $1,000.
The new measures, which are an element of Palau's new Responsible Tourism Education Act, came into force on Wednesday.
They form just one part of a broader government goal to safeguard the island nation's environment from tourists.

China's courier industry is expected to handle 74 billion parcels this year, according to the country's postal service regulator, an average of 52 deliveries per person.

According to the bureau, over 63 billion parcels were delivered through express delivery last year, up 24% year-on-year. The sector raked in 745 billion yuan in revenues, surging 23%.

Ma also stressed that the country will step up efforts in strengthening the interconnection of the global postal network and promoting the development of international postal services this year with the focus on Southeast Asia.
