New Plans Show Autonomous Submarine Designed To Explore The Oceans Of Jupiter’s Moon

Posted by in categories: alien life, engineering, robotics/AI

It’s often said that we know more about the Moon than our own oceans. But what about the oceans of other moons?

Robotic-engineering company German Research Center for Artificial Intelligence (DFKI) has been working on the EurEx (Europa Explorer) project, which includes conceptual plans for a robotic system capable of exploring Europa’s icy subterranean oceans.

New optical material offers unprecedented control of light and thermal radiation

Posted by in categories: engineering, nanotechnology

Abstract: Columbia Engineers discover that samarium nickelate shows promise for active photonic devices — SmNiO3 could potentially transform optoelectronic technologies, including smart windows, infrared camouflage, and optical communications.

A team led by Nanfang Yu, assistant professor of applied physics at Columbia Engineering, has discovered a new phase-transition optical material and demonstrated novel devices that dynamically control light over a much broader wavelength range and with larger modulation amplitude than what has currently been possible. The team, including researchers from Purdue, Harvard, Drexel, and Brookhaven National Laboratory, found that samarium nickelate (SmNiO3) can be electrically tuned continuously between a transparent and an opaque state over an unprecedented broad range of spectrum from the blue in the visible (wavelength of 400 nm) to the thermal radiation spectrum in the mid-infrared (wavelength of a few tens of micrometers). The study, which is the first investigation of the optical properties of SmNiO3 and the first demonstration of the material in photonic device applications, is published online today in Advanced Materials.

“The performance of SmNiO3 is record-breaking in terms of the magnitude and wavelength range of optical tuning,” Yu says. “There is hardly any other material that offers such a combination of properties that are highly desirable for optoelectronic devices. The reversible tuning between the transparent and opaque states is based on electron doping at room temperature, and potentially very fast, which opens up a wide range of exciting applications, such as ‘smart windows’ for dynamic and complete control of sunlight, variable thermal emissivity coatings for infrared camouflage and radiative temperature control, optical modulators, and optical memory devices.”

Vint Cerf’s Outlook for the Internet He Helped Create

Posted by in categories: cybercrime/malcode, engineering, internet

Internet pioneer Vint Cerf sees a secure future for the network of networks he helped create four decades ago as the co-developer of TCP/IP, the protocol that facilitates internet communications.

“We’re much more conscious of the need to make the system more secure than it has been,” Cerf, Google’s chief internet evangelist, says in an interview with Information Security Media Group. “And there’s a lot going on in the Internet Engineering Task Force [an international community of network designers, operators, vendors and researchers] to achieve that objective. And I anticipate in the course of the next decade or so that we will actually see a lot more mechanisms in place in order to enhance security and privacy and safety.”

But if internet security isn’t improved, Cerf says, “people will decide it’s not an environment they find worthy of trust, in which case they’ll look for something else. Maybe, something will replace the internet that’s more secure than it is today.”

Engineers give new meaning to the phrase ‘cool clothes’

Posted by in categories: climatology, energy, engineering, habitats, sustainability

Cannot wait for this material so that I can finally enjoy my run in the park near my US home in August.


WASHINGTON — Engineers have created clothing for a warming world — a fabric that allows your body heat to escape far better than other materials do.

It hasn’t been worn or tested by humans, so outside experts caution this is far from a sure thing, but a team at Stanford University engineered a fabric using nano technology that not only allows moisture to leave the body better, but helps infrared radiation escape better. As a result, they say in Thursday’s journal Science, the body should feel around 4.8 degrees (2.7 degrees Celsius) cooler than cotton and 3.8 degrees (2.1 degrees Celsius) chillier than commercially available synthetics.

Hacking microbes

Posted by in categories: biotech/medical, engineering, food

Biology is the world’s greatest manufacturing platform, according to MIT spinout Ginkgo Bioworks.

The synthetic-biology startup is re-engineering yeast to act as tiny organic “factories” that produce chemicals for the flavor, fragrance, and food industries, with aims of making products more quickly, cheaply, and efficiently than traditional methods.

“We see biology as a transformative technology,” says Ginkgo co-founder Reshma Shetty PhD ’08, who co-invented the technology at MIT. “It is the most powerful and sophisticated manufacturing platform on the planet, able to self-assemble incredible structures at a scale that is far out of reach of the most cutting-edge human technology.”

Journey to Mars in Less than Two Days Onboard this Radical Train Concept

Posted by in categories: engineering, environmental, space travel

As for the maximum distance the train could journey, “There is no limit,” Bombardier asserts. He reckons the first ship would shuttle cargo and travelers between Earth and the Moon—a trip that would take roughly seven hours to complete at the ideal speed of 15 km/s. “The Moon will serve as a launching pad for other projects, because it is easier to assemble and build this kind of train in the absence of gravity,” he says. “And Mars seems to be a good candidate for the next phase, especially if we can terraform it.”

Though intriguing, the notion begs many questions, and likely won’t be viable for eons. “Obviously there is a lot to consider,” the designer admits. “The general purpose here is to devise a system to transport minerals, materials, and humans from one place to the other in our solar system. Solar Express is a basic idea, and we would like to know how we could improve it.”

China’s Race to Space Domination: To Try to Gain an Edge Here on Earth, China is Pushing Ahead in Space

Posted by in categories: energy, engineering, quantum physics, robotics/AI, space

More on China’s race on Space. Last Tuesday, China launched the 1st Quantum Satellite. In 2017, China is planning to be the dominant force in mining of Space. First stop — mining the dark side of the moon. Given China’s own history with environmental pollution plus mining’s damaging effects to the environment when not properly managed; etc. one must ponder how will space and Earth itself be impacted by such mining.


Before this decade is out, humanity will go where it’s never gone before: the far side of the moon. This dark side — forever facing away from us — has long been a mystery. No human-made object has ever touched its surface. The mission will be a marvel of engineering. It will involve a rocket that weighs hundreds of tons (traveling almost 250,000 miles), a robot lander, and an unmanned lunar rover that will use sensors, cameras, and an infrared spectrometer to uncover billion-year-old secrets from the soil. The mission also might scout the moon’s supply of helium-3 — a promising material for fusion energy. And the nation planting its starry flag on this historic trip will be the People’s Republic of China.
