A robot just implanted two 3D-printed teeth into a woman's mouth all on its own.

The procedure took place recently in China and the researchers who developed it hope it can help the country's dentist shortage problem, reports the South China Morning Post.

Prior to the surgery, the robot was oriented to the patient's head and mouth and researchers then programmed the device with all of the necessary information for it to complete the procedure – that included the angles and depth required for accurate placement of the implants.

After testing the programmed movements, the operation was carried out.

It took about an hour and though medical staff were present during the procedure, none of them assisted the robot while it worked.

Afterwards, the staff determined that the robot had implanted the teeth with high precision. engadget.com
Russia's foreign minister has likened the war of words between Donald Trump and Kim Jong-un to a kindergarten fight between children.

The North Korean leader earlier labelled Mr Trump "mentally deranged" and a "dotard" after Mr Trump threatened to destroy his country.

Mr Trump responded with a tweet calling Kim Jong-un "a madman" who "will be tested like never before!"

Moscow's Sergei Lavrov said a pause was needed, "to calm down the hotheads".

"Yes, it's unacceptable to silently watch North Korea's nuclear military adventures but it is also unacceptable to unleash war on the Korean Peninsula," he said. bbc.com
A failing dam is causing "extremely dangerous" flooding on a Puerto Rico river in the wake of Hurricane Maria, authorities say.

The National Weather Service (NWS) said the "imminent failure" of the Guajataca Dam is a "life-threatening situation".

More than 70,000 people live in the nearby areas of Isabela and Quebradillas.

Operators of the Guajataca Dam said the structure, at the northern end of Lake Guajataca in northwest Puerto Rico, began to show signs of failing at 14:10 local time (18:10 GMT).

It sparked a flash flood emergency for Isabela and Quebradillas municipalities, the NWS said in a series of tweets.

The agency urged residents in the area to "move to higher ground now" in an alert posted on its website. bbc.com
