Columbia University Researchers Invent Way to Simultaneously 3D Print and Cook Food

Columbia University Researchers Invent Way to Simultaneously 3D Print and Cook Foodby Clare Scott | Dec 28, 2018
3D printed food has been around for a while, but compared to other areas of 3D printing, it’s still relatively undeveloped. For the most part, 3D printed food consists of already-mixed ingredients being extruded into fun shapes. Chocolate is a popular medium, as are other foods that don’t need to be cooked afterwards. But a group of researchers from Columbia University has created a machine that can both 3D print food and simultaneously cook it, opening up possibilities for a wider variety of 3D printed foods.
“We call it digital food because we are looking at food in a new way,” said PhD researcher Jonathan Blutinger.  “The food has been slightly pulverized into a way that it can be distributed through a nozzle and we can move a gantry around and create complex geometries to create interesting shapes with the food. We are shining a laser at two mirrors controlled by motors a…

Eshchar Ben-Shitrit grew up on a kibbutz where his mother ran the dairy farm. He observed the strong bond between cows and their calves, and this memory triggered something in him when he became a father four years ago.
“When my first son was born I felt it was not possible to eat meat anymore. I felt I’d be eating someone else’s child,” Ben-Shitrit tells ISRAEL21c. “I got obsessed with finding a solution for people who enjoy meat, like me, but don’t want to eat animals.”
Using professional expertise honed at printing companies including HP Indigo and Highcon, Ben-Shitrit quit his job earlier this year and founded Jet-Eat. Working with food scientists, he’s developing 3D printing technologies to produce plant-based “beef” with t…

‘Stop Robocalling Me!’; ‘I Didn’t!’
Robocall recipients lash out, unaware that numbers on the other end may have been ‘spoofed’ by scammers

Jeffrey Lewis Knapp saves the four to six telephone numbers his caller ID logs each day. At night he seeks his revenge, calling back the people he thinks are illegal robocallers. “How can I help you?” the Arizona-based retiree says he asks the people who answer.
The problem with Mr. Knapp’s approach: He sometimes calls people who didn’t, in fact, call him first. Instead, the individuals he calls are themselves victims of a phone-related crime called malicious number spoofing, in which callers falsify their number to disguise their identities. “A lot of times they don’t know that their number was used,” said Mr. Knapp, 66. “I had one guy get a little irritated and hung up, but most are pretty positive.”
Americans’ growing battle against illegal robocallers has reached a boiling point, with victims…

Futuristic micro-robots could make roadworks a thing of the past

Futuristic micro-robots could make roadworks a thing of the past
Grants totalling £26.6m will fund projects including the development of tiny devices to repair cracks in pipes without the need to dig up roads.
Last updated: 31 December 2018 - 6.32am
The Government is investing millions of pounds in the development of futuristic micro-robots designed to work in underground pipe networks and dangerous sites like nuclear decommissioning facilities.
It is hoped that devices developed in British universities will spell the end for many disruptive and expensive roadworks, as robots carry out repairs without the need to dig up the roads.
Airborne and underwater versions could also inspect and maintain difficult-to-reach locations such as offshore wind farms and oil and gas pressure vessels.
Science minister Chris Skidmore announced investment totalling £26.6 million in 15 projects, including the plan to develop robots for work in underground pipes.
Led by Professor Kirill Horoshenkov at the…

Researchers develop artificial fingerprints, claiming they could hack into a third of smartphones

Researchers develop artificial fingerprints, claiming they could hack into a third of smartphones
·Researchers at New York University and the Michigan State University have developed images of fingerprints that have the potential to unlock devices. ·They told CNBC their findings suggested such an attack could be profitable for hackers. ·The way devices store images of fingerprints could be made more secure, the researchers said.

Artificial fingerprints have been developed by researchers who say they could one day be used to hack into everyday devices.
Researchers from New York University and Michigan State University successfully generated what they call "DeepMasterPrints" earlier this year. These are machine-learning methods that act as a kind of "masterkey" which, the researchers claim, have the potential to unlock around one in three fingerprint-protected smartphones.
In the paper released in October, the authors said syn…

Inside Facebook’s Secret Rule Book for Global Political Speech

Inside Facebook’s Secret Rulebook for Global Political Speech
Under fire for stirring up distrust and violence, the social network has vowed to police its users. But leaked documents raise serious questions about its approach.

MENLO PARK, Calif. — In a glass conference room at its California headquarters, Facebook is taking on the bonfires of hate and misinformation it has helped fuel across the world, one post at a time.
The social network has drawn criticism for undermining democracy and for provoking bloodshed in societies small and large.
But for Facebook, it’s also a business problem.
The company, which makes about $5 billion in profit per quarter, has to show that it is serious about removing dangerous content. It must also continue to attract more users from more countries and try to keep them on the site longer.
How can Facebook monitor billions of posts per day in over 100 languages, all without disturbing the endless expansion that is core to its…

In late November, the Justice Department unsealed indictments against eight people accused of fleecing advertisers of $36 million in two of the largest digital ad-fraud operations ever uncovered. Digital advertisers tend to want two things: people to look at their ads and “premium” websites — i.e., established and legitimate publications — on which to host them.
The two schemes at issue in the case, dubbed Methbot and 3ve by the security researchers who found them, faked both. Hucksters infected 1.7 million computers with malware that remotely directed traffic to “spoofed” websites — “empty websites designed for bot traffic” that served up a video ad purchased from one of the internet’s vast programmatic ad-exchanges, but that were designed, according to the indictments, “to fool advertisers into thinking that an impression of their ad was served on…
