A new study has found that a faster metabolism is the main reason that humans were able to evolve bigger brains than other closely related apes. Humans burned 635 more calories per day than gorillas, and a whopping 820 more calories per day than the orangutans in the study.
Although the study findings seem promising, more research on the issue is required since the research was performed only on adults.
Scientists have sustained human embryos in a petri dish for 13 days, shattering the previous record of nine days. The breakthrough will allow researchers to study early fetal development in unprecedented detail, and brings us one step closer to viable “artificial wombs.” But it’s adding fuel to an already heated ethical debate.
Two separate papers published this week, one in Nature and one in Nature Cell Biology, have reported culturing human embryos for nearly two weeks, going well beyond previous efforts. There’s no reason to believe that the embryos couldn’t have survived beyond the two-week mark, but the experiment had to be halted to adhere to the internationally agreed 14-day limit on human embryo research.

Gearing up to offer one-gigabit-per-second Internet service in five U.S. cities this year. The first five cities to see the blazing speed are Nashville, Atlanta, Chicago, Detroit, and Miami.
Comcast, the Internet provider everyone loves to hate, is gearing up to offer one-gigabit-per-second Internet service in five U.S. cities this year. The first five cities to see the blazing speed are Nashville, Atlanta, Chicago, Detroit, and Miami. In line with Google Fiber, Verizon FiOs, and municipal offerings at one-gigabit speeds to the home, the new Comcast service will dramatically increase download speeds. Most subscribers currently receive download speeds of 25–100 megabits per second. For the customers with a 100Mbps connection, the increase boosts their speed 10 times over. For customers with 25 megabit connections, it’s 40 times faster. At that rate, one could download a full-length HD movie in around seven seconds. Not bad.
What sets Comcast’s gigabit service apart is the fact that the Internet provider is not using fiber optic lines to achieve the mega-fast speeds. Instead the company is using the existing coaxial cable lines that are already piped into people’s homes, giving Comcast a potentially huge advantage over a project like Google Fiber—which requires digging costly trenches through cities to lay fiber cables.
Hardware Boost
Comcast’s gigabit-over-coax Internet requires a new kind of cable modem. That device is charmingly classified under a new DOCSIS 3.1 standard, an acronym for Data Over Cable Service Interface Specification. And while it looks like any other black box, this new standard is capable of pumping data at 10 Gbps over existing coaxial cable. Still, Comcast is ushering in its new service with only a tenth of that power—currently offering one gigabit per second downstream speeds with 35Mbps upstream.
The Illinois-based Northwestern University has utilized 3D printing technology to research a variety of vital applications, from 3D printing fuel cells to 4D printing materials on the nanoscale. Now, researchers from the prestigious institution are looking at 3D printing technology through a unique lens—a terahertz lens, to be exact. Generally unknown within the electromagnetic spectrum, hidden in between the more commonly known wavelengths of microwaves and infrared, lies the information-packed terahertz spectrum. The terahertz is not only a forgotten frequency, it’s also rarely studied, let alone well understood, yet it has high value in applications regarding imaging and communications.
One research group, led by Northwestern University’s Cheng Sun, has used metamaterials and a unique style of SLA technology called projection micro-stereolithography to manufacture a novel lens capable of working with terahertz frequencies. The 3D printed terahertz gradient-refractive index lens has better imaging capabilities than other commonly used lenses, and also enables researchers to make more advances with the relatively unknown world of the terahertz.
Blockchaining coming to healthcare digital services.
Blockchain and digital health services could be a perfect match for each other across a variety of applications. From distributed interoperable health records to proof of adherence for medication, the healthcare industry is ripe for digital innovation. More generally, technology is a hyper-deflationary force, and this could be particularly effective in delivering quality health care through more effective channels such as mobile apps.
Investments in the digital health space have increased significantly in the past two years. This is largely possible because of improved low-power sensors and user-friendly cloud platforms that interface with those hardware devices. The Rock Health Funding Database shows a $4.5 billion increase in venture funding in digital health from 2014 to 2015.
Smart contract technology is built on top of virtual currencies such as Bitcoin and is a hallmark of “Bitcoin 2.0” platforms. Blockchain is the fundamental infrastructure needed for Bitcoin transactions to work, and an enabling technology for the next generation of asset-based platforms.
Unencumbered by red tape, these venture-backed companies believe that they can find a faster, cheaper way to fusion than government-sponsored projects, and some very influential people agree: besides Bezos, Microsoft cofounder Paul Allen and PayPal cofounder Peter Thiel are also backing firms at the forefront of fusion development.
The founders of Amazon and Microsoft are putting their fortunes into little-known fusion energy companies. Jonathan Frochtzwajg digs into a story that has strange parallels with fiction.
My new Vice Motherboard article on environmentalism and why going green isn’t enough. Only radical technology can restore the world to a pristine condition—and that requires politicians not afraid of the future:
I’m worried that conservatives like Cruz will try to stop new technologies that will change our battle in combating a degrading Earth
But there are people who can save the endangered species on the planet. And they will soon dramatically change the nature of animal protection. Those people may have little to do with wildlife, but their genetics work holds the answer to stable animal population levels in the wild. In as little as five years, we may begin stocking endangered wildlife in places where poachers have hunted animals to extinction. We’ll do this like we stock trout streams in America. Why spend resources in a losing battle to save endangered wildlife from being poached when you can spend the same amount to boost animal population levels ten-fold? Maye even 100-fold. This type of thinking is especially important in our oceans, which we’ve bloody well fished to near death.
As a US Presidential candidate who believes that all problems can be solved by science, I believe the best way to fix all of our environmental dilemmas is via technological innovation—not attempting to reverse our carbon footprint, recycle more, or go green.
As noted earlier, the obvious reason going green doesn’t work—even though I still think it’s a good disciplinary policy for humans—is the sheer impossibility of getting the developed world to stop… well, developing. You simply cannot tell an upcoming Chinese family not to drive cars. And you can’t tell a burgeoning Indian city to only use renewable resources when it’s cheaper to use fossil fuels. You also can’t tell indigenous Brazilian parents to stop poaching when their children are hungry. These people will not listen. They want what they want, and are willing to partially destroy the planet to get it—especially when they know the developed world already possesses it.
Satellites operators have been longing for it for decades, and DARPA (once again?) is turning their dream into reality: on March 25, one of America’s most futuristic agency announced it would launch a public-private partnership to provide in-orbit servicing to geosynchronous satellites, both commercial and military.
The program dubbed Robotic Servicing of Geosynchronous Satellites (RSGS) will be a major breakthrough for the satellite industry world. Since Sputnik’s launch, the biggest weakness of satellites was that, once on orbit, nothing could be done if something went wrong or once the fuel tank ran dry. A rather embarrassing issue when considering how pricey such platforms are. The only maintenance and repair operations performed to date were manned (Hubble telescope, ISS). The agency announced that it would allocate RSGS $500mn over the next few years, supplemented by commercial partner investment.
DARPA’s RSGS is composed of two elements: the arm that will dock and manipulate the satellite, and the space ship carrying it. Regarding the first element, the agency will provide its Front-end Robotics Enabling Near-term Demonstration (FREND) technology. The prototype of the FREND arm was built for the agency by the California-based company Alliance Space Systems. The robotic arm will enable it to dock with satellites and carry out maintenance.
