We can’t see something behind a wall unless there is a mirror nearby that can capture the object’s reflection. But a new camera developed by researchers from the universities of British Columbia and Bonn has no such limitations. The camera reconstructs scattered rays of light to accurately depict images of objects that are completely outside its immediate field of view.
The camera measures incoming light rays and records not only the direction that each one comes from, but also how long it took the light to travel from its source to the camera. From these time-of-flight measurements, it is able to fully reconstruct an image of the object.
“In principle, we are measuring nothing other than the sum of numerous light reflections which reached the camera through many different paths and which are superimposed on each other on the image sensor,” says Mattias Hullin, University of Bonn computer-science professor and one of the camera’s engineers.
In a recent demo, the researchers positioned the camera on one side of a partition. On the other side, completely concealed from the camera, were a canvas and a laser beam shining onto the canvas’s center. The camera portrayed the canvas and laser beam on its video screen.
Currently, the camera’s image reconstructions are very low-resolution, but Hullin hopes that higher precision will be achievable as the technical components and mathematical models improve. The camera could have many applications in telecommunications, remote sensing, and medical imaging, he adds. —Rick Docksai ?

It’s no big deal if a salamander loses a leg—its body simply responds by growing a new one. Researchers from University College London are examining how salamanders regenerate body parts in the hopes that this information could be used to grow human cells in the future.
The secret, the researchers found, is in a cellular protein chain known as the ERK pathway, which allows proteins to deliver signals from the cell’s surface to its nucleus. When a body part is severed, activated ERK proteins trigger the remaining cells to reprogram and multiply. Salamanders’ ERK pathways are constantly active, which explains their ability to regrow lost tails, legs, and even hearts.
Humans and other mammals can’t regrow limbs because their ERK pathways aren’t fully active. But, when artificially activated, mammalian cells show greater potential for reprogramming and regrowth. Future research focusing on regulating ERK pathways could lead to better medical technology for humans.
“This mechanism could contribute to therapies directed at enhancing regenerative potential of human cells,” explains molecular biologist Max Yun, lead author of the study. —Keturah Hetrick ?

Water-challenged communities in Tanzania can channel sun or wind power to generate whole new reservoirs of safe drinking water, thanks to a water-filtration system developed by engineers from the Karlsruhe Institute of Technology (KIT), a public corporation in Baden-Württemberg, Germany. The engineers field-tested their system in several rural Tanzanian communities in February and March this year, and they found that it successfully cleared water of microbes and harmful pollutants at each.
KIT hydraulic engineer Andrea Schäfer and photovoltaics expert Bryce Richards, the system’s co-developers, call their creation the Reverse Osmosis Water Installation (ROTI). The design combines one set of membranes that has pores measuring 50 nanometers wide (small enough to sequester pollutants, bacteria, and viruses) with another set of membranes whose pores are only a single nanometer wide and filter out individual dissolved molecules of those pollutants.
ROTI is designed to run on either solar power, wind power, or both. And it is easily transportable from one community to another. One system can supply enough drinking water for 50 people.
The system is now undergoing further testing back home in KIT’s lab. If the test results are satisfactory, KIT will return to the Tanzanian field-test sites to install new ROTIs for residents’ permanent use. —Rick Docksai ?

With nearly 118 boys born for every 100 girls, China has the world’s greatest gender imbalance. While China’s preference for sons stretches back hundreds of years, some of the country’s current gender imbalance can be attributed to the government’s one-child policy, as well as better health care and food for infant males. However, the greatest cause of the disparity is sex-selective abortion—a practice that’s been prevalent since the 1980s, when ultrasounds became commonplace.
The gender gap affects many areas of society, leading to high competition among men seeking girlfriends and wives, a stunted population growth rate, and even greater criminal activity. From 1988 to 2004, growing numbers of unskilled, unmarried men coincided with a 3% increase in violent crimes and property crimes across the country, according to a study published in Asian Population Studies. And crime will likely continue to increase along with the growth in “surplus men”: By 2030, the researchers estimate, the number of unskilled, unmarried men will grow to between 27 million and 50 million.
The Chinese government is seeking to regulate the growing sex-at-birth ratio. While there are many policies the country could pursue, the researchers note that changes wouldn’t have an immediate effect and could negatively impact parts of the economy. —Keturah Hetrick ?

We were saddened to learn recently of the death of longtime world future society supporter Arnold Brown, chairman of Weiner, Edrich, Brown, Inc. (WEB).
Arnold served as chairman of the World Future Society’s board of directors (2006-2007) and participated in WFS activities as recently as the 2013 annual conference in Chicago. He was also a prolific business trends analyst, researcher, and writer, contributing numerous articles and book reviews to THE FUTURIST magazine.
“Arnold was an extremely intelligent and thoughtful man, who was passionate about his work and studying the future,” said Jared Weiner, vice president of WEB. “His integrity, his generosity and his commitment made an indelible impact on us personally, on our business, on the World Future Society and on the futures field in general. He was a true pioneer, visionary, and all-around wonderful man. He will be deeply missed.”
In lieu of flowers or cards, the family suggests that gifts in Arnold’s memory be made to the Visual Arts Foundation for the Pamela Roberts Memorial Scholarship at the School of Visual Arts, 220 E. 23rd Street, Suite 609, New York, New York 10010.

How do they get energy? They use electromagnetic waves, the same waves used by radios and microwaves. It is a form of electromagnetism. In the case of the pacemaker the technology is neither the one used by radios or microwaves but something in between. Called mid-field wireless transfer, the technology blends the two types of electromagnetic waves currently in use. Read more.
As futurists or as individuals, we all read about how current research and development will change our world and our lives. Yet much that is written focuses on things and research, and not much on how our lives may or will be changed. But how does future change affect YOU? Let’s start with an easy one, self-driving cars. Sounds easy, but reality may be more complex, so here are some possibilities. Read more.
Brewing a cup of tea seems simple enough. But to a robot, seemingly straightforward tasks can actually be pretty complicated and ambiguous. Researchers at Cornell University have developed a robot that learns information about your speech and its environment and uses that information to carry out commands. And programming the robot is easy—It learns from spoken instructions. Read more.
