None, so far, claim to have cracked the problem completely.
A Thai man who broadcast himself killing his 11-month-old daughter in a live video on Facebook this week, was the latest in a string of violent crimes shown live on the social media company. The incidents have prompted questions about how Facebook's reporting system works and how violent content can be flagged faster.
A dozen or more companies are wrestling with the problem, those in the industry say. Google - which faces similar problems with its YouTube service - and Facebook are working on their own solutions.
Most are focusing on deep learning: a type of artificial intelligence that makes use of computerized neural networks. It is an approach that David Lissmyr, founder of Paris-based image and video analysis company Sightengine, says goes back to efforts in the 1950s to mimic the way neurons work and interact in the brain.

Rassim Khelifa from the University of Zurich, Switzerland, witnessed the behavior for the first time in the moorland hawker dragonfly (Aeshna juncea). While collecting their larvae in the Swiss Alps, he watched a female crash-dive to the ground while being pursued by a male.
The female then lay motionless on her back. Her suitor soon flew away, and the female took off once the coast was clear.
"I was surprised," says Khelifa, who had never previously seen this in 10 years of studying dragonflies.

"It's a great breakthrough," says Chris Stringer, an anthropologist at the Natural History Museum in London. "Anyone who's digging cave sites from the Pleistocene now should put [screening sediments for human DNA] on their list of things that they must do." Adds Svante Pääbo, the head of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, where the work was done: "I think this will become a standard tool in archaeology, maybe even like radiocarbon dating."

Testing has been ongoing for the past two weeks at Camp Pendleton in California, as part of the Ship-to-Shore Maneuver Exploration and Experimentation Advanced Naval Technology Exercise 2017, Fox News reported Thursday.
From quadcopter drones to surf and sand-ready weaponized autonomous vehicles, the US Navy and Marines are seeking to avoid detection, conduct surveillance, free up manpower and ultimately lessen the risks that come with storming beaches. They are expected to narrow down what's needed most from roughly 50 machines being tried out.

Due to its small size, the host star does not produce enough heat to support life on the planet. This has prompted scientists to label the world - nominally called OGLE-2016-BLG-1195Lb - the 'iceball' planet.
An international team of researchers found the planet using a technique known as 'microlensing,' which uses background stars as flashlights that mark out planets as dark dots when they cross the field of light.
"This iceball planet is the lowest-mass planet ever found through microlensing," said Yossi Shvartzvald, a NASA postdoctoral fellow based at the space agency's Jet Propulsion Laboratory in Pasadena, California.

Watts Up With That?

First up, Bill led the march for science with Mike Mann recently....
...and then had a bizarre episode of his Netflix show that immediately followed. From Natural News:
Surgeon claims cryogenically frozen brains will be 'woken up' and transplanted in donor bodies within three years
Thu, 27 Apr 2017 15:20 UTC
Professor Sergio Canavero, Director of the Turin Advanced Neuromodulation Group, is aiming to carry out the first human head transplant within 10 months and then wants to begin trials on brain transplants.
If the procedures are successful, he believes that frozen brains could be thawed and inserted into a donor body.

The gap between the rings and the top of Saturn's atmosphere is about 2,400km (1,500 miles) wide. Cassini passed through the gap at speeds of about 123,000kph (77,000mph) on Wednesday as part of the craft's final exploratory mission dubbed the 'Grand finale.'
The craft used its dish-shaped antenna as a shield against oncoming particles while it travelled through the region as scientists feared that even small particles could have disabled the spacecraft. Using the dish in this way forced Cassini to lose contact with Earth.

The company, owned by Google, has been testing ways to use the dexterous machines in different settings. Until now, the robots have only really been used in military settings.
Called Spot, the four-legged version of Boston Dynamics' automaton can jump, run, climb stairs, get back up if it falls, and perform human tasks such as house work. It can also now deliver packages strapped to its back, the company said.
