A team of researchers from the University of New South Wales (UNSW) in Sydney developed a new ink made of calcium phosphate and a technique known as ceramic omnidirectional bioprinting in cell-suspensions (Cobics). The process enabled them to print bone-like structures that harden in minutes when placed in water.

Parts of Victoria and New South Wales are sweating through an extreme heatwave that started sweeping across Australia s southeast yesterday.
This may seem like just a good excuse to go to the beach, but as the planet heats up and escalating temperatures become less bearable it creates more and more significant challenges to everyday life.
Already, heat kills more people in Australia than any other natural disaster, including floods, cyclones and bushfires.
Now, faced with the prospect of 50-degree-plus summers, experts say highly urbanised parts of Australia may become unliveable within decades.
The race is on to re-imagine, redesign and rebuild the Australian suburb.
The cruel and seemingly outdated Twitter advertisement in question led to a story that claimed Rebel Wilson and other celebrities "completely ruined their looks."

China passed a new law Friday granting its coast guard more leeway in asserting Chinese claims in the contested South China Sea and authorizing the use of force against foreign vessels.
The National People’s Congress passed the Coast Guard Law of the People’s Republic of China to help the China Coast Guard defend “national sovereignty, security, and maritime rights and interests.”
Since it was founded in 2013, the CCG has operated across the South China Sea, which is the site of overlapping maritime and territorial claims between China, the Philippines, Vietnam, Taiwan, Malaysia, and Brunei. In 2018, the CCG was transferred from the State Oceanic Administration to the People’s Armed Police, making it part of China’s military.

Hanoi’s air quality continues worsening
Hanoi’s air pollution has continued worsening in many areas, posing health risks for local residents.
According to the Hanoi Department of Natural Resources and Environment, the air quality index at the city’s 34 air monitoring stations this morning, January 21 faced extremely severe pollution. Four stations located in Thanh Xuan District, Cau Giay District and Hoan Kiem District had the worst results.
The department’s Environmental Protection Board said that the content of high fine particulate matters of PM 2.5 and PM 10 increased by 1.3-2 times against the day before.
Weather conditions with the thick dense smog and high moisture is among the major causes of the serious pollution in the city, the board added.
