As reported by Bloomberg, Tesla has acquired the innovative energy storage company Maxwell Technologies for $218 Million. The move is a direct departure from Tesla’s current energy storage requirements; instead of relying on lithium battery technology, this acquisition could signal a change to capacitor technology.
The key selling point of capacitors, either of the super- or ultra- variety, is the much shorter charge and discharge rates. Where a supercapacitor can be used to weld metal by simply shorting the terminals (don’t do that, by the way), battery technology hasn’t yet caught up. You can only charge batteries at a specific rate, and you can only discharge them at a specific rate. The acquisition of an ultracapacitor manufacturer opens the possibility of these powerhouses finding their way into electric vehicles.
While there is a single problem with super- and ultra-capacitors — the sheer volume and the fact that a module of ultracaps will hold much less energy than a module of batteries of the same size — the best guess is that Tesla won’t be replacing all their batteries with caps in the short-term. Analysts think that future Teslas may feature a ‘co-battery’ of sorts, allowing for fast charging and discharging through a series of ultracapacitors, with the main energy storage in the car still being the lithium battery modules. This will be especially useful for regenerative braking, as slowing down a three thousand pound vehicle produces a lot of energy, and Tesla’s current battery technology can’t soak all of it up.
The wheels of government move slowly, far slower than the pace at which modern technology is evolving. So it’s not uncommon for laws and regulations to significantly lag behind the technology they’re aimed at reigning in. This can lead to something of a “Wild West” situation, which could either be seen as a good or bad thing depending on what side of the fence you’re on.
In the United States, it’s fair to say that we’ve officially moved past the “Wild West” stage when it comes to drone regulations. Which is not to say that remotely controlled (RC) aircraft were unregulated previously, but that the rules which governed them simply couldn’t keep up with the rapid evolution of the technology we’ve seen over the last few years. The previous FAA regulations for remotely operated aircraft were written in an era where RC flights were lower and slower, and long before remote video technology moved the operator out of the line of sight of their craft.
To address the spike in not only the capability of RC aircraft but their popularity, the Federal Aviation Administration was finally given the authority to oversee what are officially known as Unmanned Aerial Systems (UAS) with the repeal of Section 336 in the FAA Reauthorization Act of 2018. Section 336, known as the “Special Rule for Model Aircraft” was previously put in place to ensure the FAA’s authority was limited to “real” aircraft, and that small hobby RC aircraft would not be subject to the same scrutiny as their full-size counterparts. With Section 336 gone, one could interpret the new FAA directives as holding manned and unmanned aircraft and their operators to the same standards; an unreasonable position that many in the hobby strongly rejected.
At the time, the FAA argued that the repealing Section 336 would allow them to create new UAS regulations from a position of strength. In other words, start with harsh limits and regulations, and begin to whittle them down until a balance is found that everyone is happy with. U.S. Secretary of Transportation Elaine L. Chao has revealed the first of these refined rules are being worked on, and while they aren’t yet official, it seems like the FAA is keeping to their word of trying to find a reasonable middle ground for hobby fliers.

What if I told you that you can get rid of your headphones and still listen to music privately, just by shooting lasers at your ears?
The trick here is something called the photoacoustic effect. When certain materials absorb light — or any electromagnetic radiation — that is either pulsed or modulated in intensity, the material will give off a sound. Sometimes not much of a sound, but a sound. This effect is useful for spectroscopy, biomedical imaging, and the study of photosynthesis. MIT researchers are using this effect to beam sound directly into people’s ears. It could lead to devices that deliver an audio message to specific people with no hardware on the receiving end. But for now, ditching those AirPods for LaserPods remains science fiction.
There are a few mechanisms that explain the photoacoustic effect, but the simple explanation is the energy causes localized heating and cooling, the material microscopically expands and contracts, and that causes pressure changes in the sample and the surrounding air. Saying pressure waves in air is just a fancy way of explaining sound.

Love it or loathe it, the pharmaceutical industry is really good at protecting its intellectual property. Drug companies pour billions into discovering new drugs and bringing them to market, and they do whatever it takes to make sure they have exclusive positions to profit from their innovations for as long a possible. Patent applications are meticulously crafted to keep the competition at bay for as long as possible, which is why it often takes ages for cheaper generic versions of blockbuster medications to hit the market, to the chagrin of patients, insurers, and policymakers alike.
Drug companies now appear poised to benefit from the artificial intelligence revolution to solidify their patent positions even further. New computational methods are being employed to not only plan the synthesis of new drugs, but to also find alternative pathways to the same end product that might present a patent loophole. AI just might change the face of drug development in the near future, and not necessarily for the better.

The biggest news in the infosec world, besides the fact that balaclavas are becoming increasingly popular due to record-low temperatures across the United States, is that leet haxors can listen to you from your iPhone using FaceTime without you even answering the call. There are obvious security implications of this bug: phones should only turn on the microphone after you pick up a call. This effectively turns any iPhone running iOS 12.1 or later into a party line. In response Apple has taken group FaceTime offline in preparation of a software update later this week.
So, how does this FaceTime bug work? It’s actually surprisingly simple. First, start a FaceTime call with an iPhone contact. While the call is dialing, swipe up, and tap Add Person. Add your own phone number in the Add Person screen. This creates a group call with two instances of your iPhone, and the person you’re calling. You may now listen in to the audio of the person you originally called even though they haven’t chosen to pick up the call. Dumb? Yes. Insecure? Horribly. If your iPhone is ringing, the person on the other end could be listening in.
But this isn’t a story about how Apple failed yet again. This is a story about how this security flaw was found, and what a normal person can do if they ever find something like this.

The sun constantly bathes half the planet with energy. The energy may be free, but the methods for converting it to electricity cost money. Last year, the Chinese government cut subsidies to their solar panel manufacturers to shrink the industry which was perceived as bloated. This forced Chinese solar panel makers to cut prices to clear inventory. This drove down prices about 30%, making solar power cheaper than ever.
Reuters is reporting that Eric Luo, president of one of the largest solar panel makers in China, predicts that “the party is definitely over.” Speaking at the World Economic Forum, Luo said that prices have quit dropping and he expected industry consolidation to cause prices to rise by as much as 15% over the next two years.

Every technological advancement seems to have a sharp inflection point, a time before which it seems like any early adopters are considered kooks, but beyond which the device or service quickly becomes so mainstream that non-adopters become the kooky ones. Take cell phones, for example – I clearly remember a news report back in the 1990s about some manufacturers crazy idea to put a digital camera in a phone. Seemingly minutes later, you couldn’t buy a phone without a camera.
It seems like we may be nearing a similar inflection point with a technology far more complex and potentially far more life-altering than cameras in cell phones: powered exoskeletons. With increasing numbers of news stories covering advancements in exoskeletal assistants for the elderly, therapeutic applications for those suffering from spinal cord injuries and neurodegenerative diseases, and penetration into the workplace – including the battlefield – as amplifiers of human effort, it’s worth taking a look at where we are with exoskeletons before seeing someone using one in public becomes so commonplace as to go unnoticed.
