For as long as she can remember, she’s puzzled over what’s out there. As a kid drifting off to sleep on a trampoline outside her family’s home near Portland, Ore., she would track the International Space Station. She remembers cobbling together a preteen version of the Drake Equation on those nights and realizing that the likelihood of intelligent alien life was something greater than zero. Star Trek marathons with her father catalyzed her cosmic thinking, as did her mother’s unexpected death when Bailey was 8. The house lost some of its order—some of its gravity—which led to more nights gazing skyward on the trampoline.

In college, Bailey got a hard-won paid internship at the now-merged aerospace giant Hamilton Sundstrand and joined a team repairing turbine engines. She hated it. “It was the opposite of pushing the envelope,” she says. “Nothing new ever went into that building. Nothing new ever left that building.”

By the time she set off to get a master’s degree in mechanical engineering at Duke University, the idea of logging 30 years at a place like Boeing Cor NASA had lost all appeal. She tried her hand at finance and later law, and was unlucky enough to excel at both. “I made it pretty far down that path, but then I thought, Wait, if I become a lawyer, then I’m a lawyer and that’s what I do,” she recalls. “What if I don’t want to do that on Tuesdays?”

3D printing refers to various processes used to manufacture three dimensional objects in successive layers of material formed under computer control.

You should already be using two-factor authentication to prevent unauthorized access to your online accounts. While your phone is up to the task of helping you with that, Google believes it’s time for to take the next step: using a physical security key.

At its ongoing Google Cloud Next event, the company announced that it’s launched the Titan Security Key, which lets you log in to your account on your desktop by authenticating your identity with over USB or Bluetooth.

Check out TNW’s Hard Fork.

Giant technology companies in the US, which include some of the world’s most profitable firms, have been pledged at least $9.3bn in state and local subsidies over the last five years – much of it coming from the coffers of cities and states with failing infrastructure, struggling schools and broken budgets.

Fostering local hi-tech success doesn’t have to mean offering huge tax breaks to companies like Apple and Amazon. Here are some alternative strategies.

These prosthetics are so realistic that it’s hard to tell what is real or fake.

Honeybee Robotics has been working on a Planetary Deep drill. It has been tested to a depth of about 100 feet (30 meters). The plan has to been to have the lightweight system reach kilometers of depth. This would be able to reach the liquid Lake on Mars.

The Planetary Deep Drill is a wire-line drill designed to reach miles below extraterrestrial surfaces. The lightweight drill meets the payload and excavation requirements required to reach far below the icy surface formations of Mars, Enceladus or Europa.

Amazon’s Echo lineup, like some smart speakers, uses proximity detection to decide which device is best-suited to responding to your voice commands. It’s a clever way to prevent multiple devices from waking up at the same time. There’s just one problem: support in non-Amazon devices has been inconsistent at best, creating a mess if you have third-party gear that doesn’t use the feature. Thankfully, that shouldn’t be an issue from here on out. Amazon has moved its Echo Spatial Perception technology to the cloud, ensuring that all devices can use it.

The ESP upgrade is automatic and doesn’t require any changes on the part of hardware makers. It’s also more accurate, according to Amazon, and can change over time as Alexa receives upgrades.

This doesn’t change some limitations for multi-device households. Many commands still apply specifically to the device where they’re set, such as reminders and timers. Even so, this could be a crucial update for Amazon. If it’s going to bring Alexa to virtually every device it can, it has to create a harmonious ecosystem.

A series of earthquakes have shaken a region of ocean off the west coast of the UScientists have detected a cluster of 11 earthquakes, ranging in magnitude from 2.8 to 5.6 on the Richter scale. The cluster occurred on the seabed at the Juan de Fuca tectonic plate, around six miles (10km) underwater. This plate forms part of the Cascadia subduction zone, which runs from Northern California to British Columbia. Previous studies have warned this geological spot of weakness has the potential to deliver an earthquake much stronger than the infamous San Andreas fault. Seismologists say a full rupture along the 650-mile-long (1,000 km) …→

The trouble with microphones is that they don’t just hear — they have to listen. Powering the mic and its signal processor means using energy, and energy means a battery, and a battery means charging. This new microphone-like system hears more like the way our own ears do, requiring little or no power, and could help fill the world with voice-responsive machines. (If that’s something we really want.)

The device is called a “triboelectric auditory sensor,” and it works via what’s called the triboelectric effect — essentially when two surfaces rub together and create a charge. They’re still trying to figure out why this happens, but what matters to engineers is that it happens reliably.

Triboelectric nanogenerators have been around for a few years, creating power by having two compatible materials interact with each other at super-small scales. While they’re tiny and highly efficient, they don’t actually produce a lot of power. Researchers from Chongqing University found that, fortunately, you don’t need a lot of power for the purposes of detecting sound.
