Researchers create living material based on algae

Researchers used 3D printers and a novel bioprinting technique to print algae into living, photosynthetic materials that are tough and resilient. The plant-like nature of the material means it can use photosynthesis to “feed” itself over periods of many weeks, and it is also able to be regenerated—a small sample of the material can be grown into more on-site. The unique characteristics of the material make it an ideal candidate for a variety of applications, including new products such as artificial leaves, or sense-and-respond materials. “We created a material that can produce energy simply by placing it into the light.”

US Army’s New Night-Vision Goggles Are Worthy of Super Soldiers

The ENVG-B goggles have a double-tubed binocular system for better situational awareness and depth perception, they have a higher resolution thanks to their phosphorescent white colors, they use a fused thermal imager, they use AR aspects, and use wireless interconnectivity. They provide the Army’s close combat forces “an extra capability to observe and maneuver in all weather conditions, through obscurants, during limited visibility, and under all lighting conditions.” Clear neon white outlines of people and artillery, detailed trees and brush, bright light blue figures, and tactical information are all displayed right in front of the soldier’s eyes.

New device uses bioluminescent bacteria to track down buried explosives

Researchers have developed a sensor that can rapidly locate buried explosives with the help of genetically engineered, bioluminescent E. coli bacteria. The team genetically engineered bacteria to detect trace amounts of dinitrotoluene, a derivative of trinitrotoluene, which is found in around 80% of buried mines. Prototypes of the scanner were highly accurate in a controlled environment, detecting as little as 0.25 milligrams of DNT per kilogram of soil. The results were achieved by engineering two sets of genes within the bacteria: “promoter genes,” which identify the DNT, and “reporting genes,” which light up to locate the presence of an explosive substance.

Fasting boosts stem cells’ regenerative capacity

Researchers found that fasting dramatically improves stem cells’ ability to regenerate, in both aged and young mice. In fasting mice, cells begin breaking down fatty acids instead of glucose, a change that stimulates the stem cells to become more regenerative. The researchers found that they could also boost regeneration with a molecule that activates the same metabolic switch. The researchers found that stem cells from the fasting mice doubled their regenerative capacity. “It was very obvious that fasting had this really immense effect on the ability of intestinal crypts to form more organoids, which is stem-cell-driven.”

One of NYC’s – and the World’s – Top Restaurants to Go Totally Meat-Free

Eleven Madison Park is considered one of the finest restaurants in both New York City and the world — and starting next month, it will also be completely meatless and almost entirely vegan. The restaurant will reopen in-person service June 10 with what the website described as “an eight to ten course menu in the main dining room consisting of entirely plant-based dishes.” The change will potentially have huge repercussions in the world of fine dining, given the restaurant’s prominence. “If Eleven Madison Park is truly at the forefront of dining and culinary innovation, to me it’s crystal clear that this is the only place to go next.”

Verizon offloads Yahoo and AOL in $5 billion deal

Verizon is exiting the media business, announcing that it’s selling the unit for $5 billion to private equity firm Apollo Global Management. The sale includes AOL and Yahoo, which Verizon bought for a combined $9 billion in recent years. Verizon will retain a 10% stake in the spin off and the Verizon Media Group name will be changed to just Yahoo. “With Apollo’s sector expertise and strategic insight, Yahoo will be well positioned to capitalize on market opportunities, media and transaction experience and continue to grow our full stack digital advertising platform.”

Australia proposes teaching cyber-security to five-year-old kids

A newly revised draft of the national curriculum for children aged five to sixteen added a new strand titled “Considering privacy and security” that “involves students developing appropriate techniques for managing data, which is personal, and effectively implementing security protocols.” The proposed curriculum aims to teach five-year-old children not to share information such as date of birth or full names with strangers, and that they should consult parents or guardians before entering personal information online. Six-and-seven-year-olds will be taught how to use usernames and passwords, and the pitfalls of clicking on pop-up links to competitions.

Child sexual abuse: Four held in German-led raid on huge network

German police have arrested three men and a fourth is being held in Paraguay for allegedly running one of the world’s biggest online networks for sharing images of child sex abuse. The international operation, involving several police forces, targeted a dark net platform called Boystown, which has now been taken down. Officials say Boystown had more than 400,000 registered users. They say some images showed the most serious sexual abuse of young children. The EU police agency Europol says it will also examine intelligence gained from the operation, and “more arrests and rescues are to be expected globally” on that basis.
