16-year-old student in Turkey turns bananas into plastic

"There’s nothing slippery about Elif Bilgin’s idea of using banana peels as a substitute for old-school petroleum-based plastics. The 16-year-old student from Istanbul spent two years perfecting a way to make a bioplastic out of discarded banana peels that could, in turn, be used for the electrical insulation of cables. In her research, Bilgin — who says 'science is my calling' — determined that if starch and cellulose from such food waste as mango skins can be used to make bioplastics, then banana peels ought to do the trick, too."

UN agency tests long-lasting Ikea refugee shelter

"Ikea's philanthropist foundation has funded the project to the tune of $4 million, while a Sweden-based group called the Refugee Housing Unit has been working with the UN agency on the design. The prototypes, with their semi-hard plastic walls and roofs made from composite material and with room to house five people each, have cost $8,000 a piece, and UNHCR wants to wait for feedback from refugees before giving a green light to more wide-scale production. The new shelters have been guaranteed to last three years and will likely remain standing for longer than that. That is a big plus considering that refugees on average live in their UNHCR shelters for 12 years." Continue reading →

3-year-old Japanese boy receives partial lung transplant from mother

"Part of a Japanese woman’s lung was transplanted to her three-year-old son Monday in what was described as the world’s first successful graft of a middle lobe from a living donor, a hospital said.

India launches first of seven navigation satellites

"India launched the first of seven satellites for its domestic satellite navigation network in the first step to creating a scaled down version of the US Global Positioning System. The United States’ GPS is the most widely used network by consumers with 24 satellites, but other countries including Russia, the European Union and most recently China have developed rival positioning systems. China’s Beidou, or Compass, navigation system is expected to offer global coverage by 2020. India has a well-established space programme, but its cost has attracted criticism as the government struggles to tackle poverty and child malnutrition." Continue reading →

Scientists invent contact lenses that bestow telescopic vision

"Researchers in Switzerland and San Diego said this week that they have developed contact lenses that can bestow telescopic vision upon the wearer. The contacts work in conjunction with a set of special glasses that wouldn’t seem that unusual by themselves. Inside the lens, a tiny ring reflects light back and forth with hundreds of aluminum mirrors. Those mirrors are positioned precisely so that all the points of light come together in an image projected onto the eye that depicts the world magnified by 2.8 times, according to the BBC. The project was funded through the U.S. Department of Defense’s research wing DARPA." Continue reading →

U.S. decision delayed on easing gadget use on airplanes

"The advisory panel was supposed to finish its work by July 31 but was granted a two-month extension to continue examining whether the use of electronic and WiFi enabled devices, such as iPods, laptops, e-readers and other gadgets, would be safe to use through takeoff and landing and at altitudes under 10,000 feet. Airlines have long told travelers not to use iPods, music players, laptops and other gadgets during takeoffs and landings. NBC News reported that the recommendations are likely to call for allowing passengers to use devices such as electronic readers throughout a flight, and that FAA officials are likely to adopt the change."

New York to Tokyo in two hours

"The engine would incorporate turbine stages not connected by a shaft, each able to rotate independently at the optimal speed for maximum aerodynamic efficiency in flight. They would spin in electromagnetic fields, using the same principle that allows high-speed trains to float frictionless above an energized track. The engine is a hybrid of turbofan, turbojet, and turbo ramjet, able to generate 40 megawatts (MW) of electricity. It uses about 9 MW of electricity to power a plasma field generator reshaping airflow around the aircraft and taming the pressure wave, turning sonic boom into a sound similar to rustling leaves on the ground."

Surveillance Self-Defense International [2010]

"The Internet remains one of the most powerful means ever created to give voice to repressed people around the world. Unfortunately, new technologies have also given authoritarian regimes new means to identify and retaliate against those who speak out despite censorship and surveillance. Below are six basic ideas for those attempting to speak without falling victim to authoritarian surveillance and censorship, and four ideas for the rest of us who want to help support them."

Bitcoin ATM launched

"A bitcoin ATM was revealed at a London conference today, allowing users to convert bank notes into the digital currency. To use the ATM, you need to have an existing Bitcoin wallet number. First, it scans a QR code of your Bitcoin address. Then, the user has to feed bank notes into the machine, which are converted at the current exchange rate and deposited into their account. While the deposit takes moments, it can take several minutes for an account to be updated. Bitcoin can be purchased via online exchange sites, but the ATM means you don't need to use a credit or bank card, helping to keep the transactions anonymous, the company said." Continue reading →

Mastercard and Visa Start Banning VPN Providers

"There’s an unwritten rule that Mastercard and Visa don’t accept file-hosting sites that have an affiliate program and PayPal has thrown out nearly all cyberlockers in recent months. It now turns out that these policies have carried over to VPN providers and other anonymizing services. Before the weekend customers of the popular Swedish payment service provider Payson received an email stating that VPN services are no longer allowed to accept Visa and Mastercard payments due to a recent policy change. The new policy went into effect on Monday, leaving customers with a two-day window to find a solution." Continue reading →
