Electric vehicles can meet drivers’ needs enough to replace 90 percent of vehicles now on the road

Posted by in categories: climatology, sustainability

Could existing electric vehicles (EVs), despite their limited driving range, bring about a meaningful reduction in the greenhouse-gas emissions that are causing global climate change? Researchers at MIT have just completed the most comprehensive study yet to address this hotly debated question, and have reached a clear conclusion: Yes, they can.

The study, which found that a wholesale replacement of conventional vehicles with electric ones is possible today and could play a significant role in meeting climate change mitigation goals, was published today in the journal Nature Energy by Jessika Trancik, the Atlantic Richfield Career Development Associate Professor in Energy Studies at MIT’s Institute for Data, Systems, and Society (IDSS), along with graduate student Zachary Needell, postdoc James McNerney, and recent graduate Michael Chang SM ‘15.

“Roughly 90 percent of the personal vehicles on the road daily could be replaced by a low-cost electric vehicle available on the market today, even if the cars can only charge overnight,” Trancik says, “which would more than meet near-term U.S. climate targets for personal vehicle travel.” Overall, when accounting for the emissions today from the power plants that provide the electricity, this would lead to an approximately 30 percent reduction in emissions from transportation. Deeper emissions cuts would be realized if power plants decarbonize over time.

Google is developing an OS called “Fuchsia,” runs on All the Things

Posted by in categories: computing, mobile phones, transportation

Every single operating system developed by Google to date has one thing in common: they’re based on the Linux kernel. Chrome OS, Android, Chromecasts, you name it. Linux has powered Google hardware for years.

However, the Linux kernel is not ideal for every situation. Especially in the case of embedded devices like car dashboards or GPS units, full-blown desktop kernels like Linux impact performance and cause other issues. There’s a massive ecosystem of operating systems designed for embedded hardware, and Google may be working on their own.

Enter “Fuchsia.” Google’s own description for it on the project’s GitHub page is simply, “Pink + Purple == Fuchsia (a new Operating System)”. Not very revealing, is it? When you begin to dig deeper into Fuchsia’s documentation, everything starts to make a little more sense.

Progress toward real life super-soldiers

Posted by in categories: bioengineering, computing, military

For three years ago U.S. Special Operations Command and DARPA announced they had started work on a super-soldier suit called TALOS (Tactical Assault Light Operator Suit) unlike anything in the history of warfare. It is engineered with full-body ballistics protection; integrated heating and cooling systems; embedded sensors, antennas, and computers; 3D audio (to indicate where a fellow warfighter is by the sound of his voice); optics for vision in various light conditions; life-saving oxygen and hemorrhage controls; and more.

It aims to be “fully functional” by 2018. “I am here to announce that we are building Iron Man,” President Barack Obama said of the suit during a manufacturing innovation event in 2014. When the president said, “This has been a secret project we’ve been working on for a long time,” he wasn’t kidding.

In 1999 DARPA created the Defense Sciences Office (DSO) and made Michael Goldblatt its director. Goldblatt saw the creation of the super-soldier as imperative to 21st-century warfare.

5 Technologies for 2031

Posted by in category: computing

What will be most interesting about the next 15 years is that unlike the last 15, which was largely defined by digital technology, the advancements to come will arise from the confluence of a number of fields.

Exponentially more powerful computing architectures will make it possible for us to work at the genomic and molecular levels and create intelligent machines. New sources of energy, as well as the ability to store that energy far more efficiently, will allow these technologies to be practical, safe and affordable.

Today, in 2016, we have largely mastered the virtual world of information. By 2031, we will have begun to master the physical world as well.

Stroke Survivor Walks Again After Doctors Inject Stem Cells Directly into Brain

Posted by in categories: biotech/medical, neuroscience

A surgical procedure that involves drilling holes and injecting stem cells into stroke patients’ brains seems to have contributed to a wheelchair-bound stroke patient regaining the ability to walk. Despite the major recovery exhibited by patients, further study must be made to investigate the true impact.

Researchers from Stanford University were “stunned” at the positive results they obtained after injecting stem cells directly into stroke patients’ brains. The discovery has created a talking point in the neuroscience community, causing researchers to re-visit and re-evaluate the notion that brain damage is permanent and irreversible.

Samsung plugs IBM’s brain-imitating chip into an advanced sensor

Posted by in categories: biotech/medical, computing, mobile phones, neuroscience

IBM’s TrueNorth, a so-called “cognitive chip,” remarkably resembles the human brain: its 4,096 cores combine to create about a million digital neurons and 256 million synapse connections. In short, like everyone’s favorite complex organ, it operates extremely quickly and consumes far less energy than typical processors. Samsung has taken the chip and plugged it into its Dynamic Vision Sensor (DVS) to process digital imagery at a blindingly fast rate.

Typical digital cameras max out 120 frames per second, but a DVS-equipped gadget can capture an incredible 2,000 fps. Unlike a conventional sensor, each pixel on Samsung’s only reacts if it needs to report a change in what it’s seeing, according to CNET. That high speed could be useful for creating 3D maps or gesture controls. At a press event on Thursday in San Jose, the company demonstrated its ability to control a TV as it recognized hand waves and finger pinches from ten feet away.

DVS is efficient like its TrueNorth chip base, and only consumes about 300 milliwatts of power. That’s about a hundredth the drain of a laptop’s processor and a tenth of a phone’s, a Samsung VP said at the event. But we still have a ways to go before we approach the minimal power requirements of the human brain, he said, which can process some tasks at 100 million times less power than a computer.
