Thrilled to see Paradromics’ $20M fund raise lead by the talented Dr. Amy Kruse! Paradromics is building a brain computer interface supported by DARPA’s Biologi… See More.

The investment demonstrates confidence in Paradromics as a well-positioned player in the $200 billion BCI therapy market. Last year, Paradromics successfully completed testing of its platform, demonstrating the largest ever electrical recording of cortical activity that exceeded more than 30000 electrode channels in sheep cortex. This recording allowed researchers to observe the brain activity of sheep in response to sound stimuli with high fidelity.

“We are combining the best of neural science and medical device engineering to create a robust and reliable platform for new clinical therapies,” said Paradromics CEO Matt Angle. “This funding round is a validation of both our technology and strategic vision in leading this important developing market.”

The Koenigsegg Gemera is a four-seat hypercar that can do 0–62 mph in a claimed 1.9 seconds, but perhaps the most remarkable thing about this Swedish rocket ship is its 2.0-liter twin-turbocharged inline-3, which makes a staggering 600 horsepower (plus 443 pound-feet of torque).

Jason Fenske at Engineering Explained has the details on how Koenigsegg extracted so much power from such a small engine. It starts with the cylinders. There may not be many of them, but they are pretty big. They’re actually larger than the cylinders in Koenigsegg’s 5.0-liter V8, Fenske noted.

Koenigsegg’s new Gemera makes over 1700 horsepower, with close to a third of that figure coming from a 3-cylinder engine.

CHINA’S NEW THORIUM-BASED NUCLEAR REACTOR is well situated for being adopted for Space applications.

China is slowly but steadily positioning itself to leap ahead of the US Space program. It is doing this without pomp and fanfare, and without the idea of a “space race,” simply based upon what it requires for its future.

1) Recent noteworthy progress on molten salt thorium reactors could be a key component of future Chinese space-worthiness. Originally designed by the USA’s Oak Ridge National Laboratory in the 1960’s, they were planned to be used for nuclear powered strategic bomber planes, before the nuclear submarine concept became adopted as more feasible. They were chosen because they can be miniaturized to the size of an aircraft. By the same token, they could conceivably be used in advanced atmospheric or space propulsion.

Plastic waste, a material that can take centuries or more to disappear, is causing irreparable damage to the planet. At least 8 million tons of plastic end up in the ocean each year. In many cases, specifically in more developed countries, plastic waste is disposed of responsibly and sent to facilities to be sorted, recycled, or recovered. However, plastic waste generated in developing countries typically ends up in dumps or open, uncontrolled landfills — most of which eventually enter the ocean either through transport by wind or tides or through waterways such as rivers or wastewater. Now, many companies are recycling this waste into useful products, such as sportswear, affordable homes, electric cars, roads, etc. One of them is Gjenge Makers Ltd, a sustainable, alternative, affordable building products manufacturing company that transforms plastic waste into durable building materials. These include paving blocks, paving tiles, and manhole covers.

Nzambi Matee has used her engineering skills to develop the process that involved mixing recycled waste plastic and sand. Matee gets the wasted plastic from packaging factories for free, although she pays for the plastic she gets from other recyclers. The company workers take plastic waste, mix it with sand, and heat it up, with the resulting brick being five to seven times stronger than concrete.

Most of the tests that doctors use to diagnose cancer — such as mammography, colonoscopy, and CT scans — are based on imaging. More recently, researchers have also developed molecular diagnostics that can detect specific cancer-associated molecules that circulate in bodily fluids like blood or urine.

MIT engineers have now created a new diagnostic nanoparticle that combines both of these features: It can reveal the presence of cancerous proteins through a urine test, and it functions as an imaging agent, pinpointing the tumor location. In principle, this diagnostic could be used to detect cancer anywhere in the body, including tumors that have metastasized from their original locations.

“This is a really broad sensor intended to respond to both primary tumors and their metastases. It can trigger a urinary signal and also allow us to visualize where the tumors are,” says Sangeeta Bhatia, the John and Dorothy Wilson Professor of Health Sciences and Technology and Electrical Engineering and Computer Science at MIT and a member of MIT’s Koch Institute for Integrative Cancer Research and Institute for Medical Engineering and Science.

Researchers at ETH Zurich have trapped a tiny sphere measuring a hundred nanometres using laser light and slowed down its motion to the lowest quantum mechanical state. This technique could help researchers to study quantum effects in macroscopic objects and build extremely sensitive sensors.

Why can atoms or elementary particles behave like waves according to quantum physics, which allows them to be in several places at the same time? And why does everything we see around us obviously obey the laws of classical physics, where such a phenomenon is impossible? In recent years, researchers have coaxed larger and larger objects into behaving quantum mechanically. One consequence of this is that, when passing through a double slit, these objects form an interference pattern that is characteristic of waves.

Up to now, this could be achieved with molecules consisting of a few thousand atoms. However, physicists hope one day to be able to observe such quantum effects with properly macroscopic objects. Lukas Novotny, professor of photonics, and his collaborators at the Department of Information Technology and Electrical Engineering at ETH Zurich have now made a crucial step in that direction. Their results were recently published in the scientific journal Nature.

Many of us swing through gates every day—points of entry and exit to a space like a garden, park or subway. Electronics have gates too. These control the flow of information from one place to another by means of an electrical signal. Unlike a garden gate, these gates require control of their opening and closing many times faster than the blink of an eye.

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Chicago’s Pritzker School of Molecular Engineering have devised a unique means of achieving effective gate operation with a form of information processing called electromagnonics. Their pivotal discovery allows real-time control of information transfer between microwave photons and magnons. And it could result in a new generation of classical electronic and quantum signal devices that can be used in various applications such as signal switching, low-power computing and quantum networking.

Microwave photons are elementary particles forming the electromagnetic waves employed in, for example, wireless communications. Magnons are the particle-like representatives of “spin waves.” That is, wave-like disturbances in an ordered array of microscopically aligned spins that occur in certain magnetic materials.

A new wearable device turns the touch of a finger into a source of power for small electronics and sensors. Engineers at the University of California San Diego developed a thin, flexible strip that can be worn on a fingertip and generate small amounts of electricity when a person’s finger sweats or presses on it.

What’s special about this sweat-fueled device is that it generates power even while the wearer is asleep or sitting still. This is potentially a big deal for the field of wearables because researchers have now figured out how to harness the energy that can be extracted from human sweat even when a person is not moving.
