This Tech Could Secure Medical Implants Against Hackers

Many of today's medical implants communicate via Bluetooth, which makes them vulnerable to hacking, but a new system could change that.

Heart Hack

An implanted medical device can dramatically improve a person’s quality of life — or even save their life outright.

However, the devices come with serious security vulnerabilities, and it’s not hard to imagine the damage a person could do by hacking someone’s pacemaker, insulin pump, or brain implant.

Now, researchers from Purdue University have found a way to prevent hackers from intercepting the wireless signals used to communicate with implanted devices — and their creation could ensure the “internet of body” remains secure in the future.

Watch This

Many people monitor their implants via electronic devices, such as smart watches or smartphones, with the implants and devices communicating over Bluetooth.

Those wireless signals can extend as far as 10 meters away from a person’s body, according to the Purdue researchers – meaning someone in the vicinity of the implant owner could intercept the information — and perhaps manipulate it.

In a new paper published in the journal Scientific Reports, the researchers detail how they created a prototype watch that avoids this issue.

Short Leash

According to the researchers, their watch can receive a signal from anywhere on a person’s body, but instead of communicating over Bluetooth, the electrical signals travel through the person’s own body fluids to reach the watch, never extending more than one centimeter beyond the person’s skin.

As a bonus, the system also requires 100 times less energy than Bluetooth, according to the researchers — but its ability to protect incredibly sensitive communications could be reason enough for the technology to replace Bluetooth for implant applications in the future.

NASA: Space Travel Is Causing Astronauts’ Herpes to Flare Up

Tests show that dormant herpes viruses reactivate in more than half the astronauts who travel on the Space Shuttle and International Space station.

Dormant Viruses

Tests show that dormant herpes viruses reactivate in more than half the astronauts who travel on the Space Shuttle and International Space station, according to new NASA research — a phenomenon the space agency says could pose problems for deep space missions.

“During spaceflight there is a rise in secretion of stress hormones like cortisol and adrenaline, which are known to suppress the immune system, ” said study author Satish Mehta, a researcher at Johnson Space Center, in a press release. “In keeping with this, we find that astronaut’s immune cells — particularly those that normally suppress and eliminate viruses — become less effective during spaceflight and sometimes for up to 60 days after.”

Less Effective

In research published last month in the journal Frontiers in Microbiology, Mehta and colleagues found that astronauts shed more herpes viruses in their urine and saliva than before or after space travel. The culprit, they suspect, is just the stress of spaceflight.

“NASA astronauts endure weeks or even months exposed to microgravity and cosmic radiation — not to mention the extreme G forces of take-off and re-entry,” Mehta said in the press release. “This physical challenge is compounded by more familiar stressors like social separation, confinement and an altered sleep-wake cycle.”

Minor Symptoms

Fortunately, symptoms were relatively rare. Out of 89 astronauts the team studied, only six experienced herpes breakouts in space, according to the paper — a rate of about seven percent.

The viral shedding also got worse the longer the astronauts were off Earth, leading researchers to worry the phenomenon could represent a challenge for deep space travel.

“While only a small proportion develop symptoms, virus reactivation rates increase with spaceflight duration and could present a significant health risk on missions to Mars and beyond,” reads the press release.

New Robot Hand Works Like a Venus Flytrap to Grip Objects

A team from MIT and Harvard has created a robot hand that's not only strong, but also soft — and it could usher in a new era in robotics.

Versatile Touch

If we want robots to take over more tasks for humans, we need to give them more versatile hands.

Right now, many robot hands can only complete specialized tasks. Ones that are strong often have trouble with tasks that require a delicate touch, and soft hands often don’t pack much of a punch when it comes to strength.

But now, a team of researchers from the Massachusetts Institute of Technology (MIT) and Harvard University have created a robot hand that’s not only strong, but also soft — and it could usher in a new era in robotics.

Show of Hands

The team drew inspiration for its hand from the origami magic ball. Rather than using some sort of finger-like grippers, their cone-shaped robot hand envelopes an object and then collapses around it, much like a Venus flytrap captures its prey.

The pressure applied is enough for the hand to lift objects up to 100 times its own weight, but it can also handle far more delicate, light objects. A video released by MIT demonstrates the hand’s ability to pick up everything from a soup can to a banana.

Soft, but Strong

University of California at Santa Cruz robotics professor Michael Wehner, who was not involved in the project, praised the hand, noting its novelty in an interview with MIT News.

“This is a very clever device that uses the power of 3-D printing, a vacuum, and soft robotics to approach the problem of grasping in a whole new way,” Wehner said. “In the coming years, I could imagine seeing soft robots gentle and dexterous enough to pick a rose, yet strong enough to safely lift a hospital patient.”

The Pentagon Wants an Orbital Space Weapon to Blast Enemy Missiles

Space Laser

You know the scene in “Akira” where Tetsuo rips a satellite space weapon out of orbit?

Now the U.S. military wants to try something similar, according to Defense One. The Pentagon is requesting hundreds of millions of dollars to ramp up space-based weaponry including particle beams and space lasers that’ll fire downward at Earthly targets — a dark vision of the militarization of space.

Ballistic Missiles

According to Defense One, a Missile Defense Agency document released this week describes the military’s ambitions to disable ballistic missiles right as they launch.

“The addition of the neutral particle Beam effort will design, develop, and conduct a feasibility demonstration for a space-based Directed Energy Intercept layer,” it reads. “This future system will offer new kill options for the [Ballistic Missile Defense System] and adds another layer of protection for the homeland.”

Orbital Weaponry

Several contractors have prepared prototype orbital weaponry designs for the Pentagon over the years, according to Defense One, but they’ve been enormous and impractical. But now officials hope advances could make such a weapon feasible for a test by 2023.

“We’ve come a long way in terms of the technology we use today to where a full, all-up system wouldn’t be the size of three of these conference rooms, right?” said a senior defense official, according to Defense One. “We now believe we can get it down to a package that we can put on as part of a payload to be placed on orbit.”

NASA Engineer: Humans Should Consider Settling Saturn’s Moon Titan

nasa-engineer-humans-settling-titan

Destination: Titan

If the Earth becomes inhabitable, a NASA engineer named Janelle Wellons says we should think about settling Saturn’s moon Titan, and she has a laundry list of reasons why — including that you might be able to fly by flapping your arms.

“It has a thick atmosphere that could help protect us from space radiation,” Wellons wrote on Reddit. “It is so dense that we could actually attach wings to our arms and fly on this moon. I don’t know, it just seems like an awesome place to live.”

Largest Moon

Wellon’s comments came in a Reddit appearance in which NASA engineers, scientists and pilots fielded questions from the public. One Redditor asked where the team would recommend settling if conditions on Earth became untenable, and Wellons chimed in with what she said was a “more interesting answer than the standard Mars or Moon response.”

“How about we consider one of the water worlds in our solar system — Titan,” she wrote. “Titan is the largest moon of Saturn, larger than the planet Mercury even, so I think we could settle with plenty room.”

Swim Good

In spite of Wellon’s enthusiasm, there are definite downsides to Titan. It only gets about one percent of the sunlight Earth does, and according to NASA’s research its maximum temperature is a wintry -292 degrees Fahrenheit.

But Wellon is still a fan.

“Now as for the conditions on the surface — not as rough as you may think,” she wrote. “Titan is the only place besides Earth known to have liquids in the form of lakes and seas on its surface. These liquids are made of methane but, armed with the right kind of protective gear, one could theoretically be able to swim without harm!”

New Rocket Engine Could Whip You From London to Sydney in 4 Hours

The makers of a new hypersonic rocket engine say it could whip flights from London to Sydney in just four hours, traveling at five times the speed of sound.

Rocket Plane

The makers of a new hypersonic rocket engine say it could whisk flights from London to Sydney in just four hours, traveling at five times the speed of sound. That’s a flight that can take 20 hours on a conventional jetliner.

According to the BBCUK company Reaction Engines says it’s gearing up to test the futuristic craft in Colorado — a startling vision of the future of transportation that could also, if the engine lives up to the hype, inform the future of spaceflight.

Screaming Fist

Reaction Engines, which has backing from the Rolls-Royce and Boeing, calls the new rocket engine the Sabre. It inhales air at lower altitudes, but works more like a rocket when it gets higher up.

“The core can be tested on the ground, but it’s the core that gets you air-breathing from the ground up to the edge of space, at which point there is no more oxygen to breathe and the system transitions to the pure rocket mode,” said Shaun Driscoll, Reaction Engines’ program director, according to the BBC.

Orbiter

The company also says the Sabre engine could push the frontiers of spaceflight, by sending crafts straight into orbit without multiple propellant stages, according to the BBC, which also reported that the the European Space Agency recently signed off on a design review for the Sabre engine.

“The positive conclusion of our Preliminary Design Review marks a major milestone in Sabre development,” ESA’s head of propulsion engineering Mark Ford told the broadcaster. “It confirms the test version of this revolutionary new class of engine is ready for implementation.”

Astronomers Just Found 83 Giant Black Holes at Universe’s Edge

An international team of researchers says it's found 83 new supermassive black holes at extreme end of the visible universe.

Hole Story

An international team of researchers says it’s found 83 new supermassive black holes at extreme end of the visible universe — by looking at light that took so long to reach Earth that it dates from the early universe.

“It is remarkable that such massive dense objects were able to form so soon after the Big Bang,” said Michael Strauss, a professor of astrophysical sciences at Princeton University involved in the research, in a press release. “Understanding how black holes can form in the early universe, and just how common they are, is a challenge for our cosmological models.”

Squad Goals

The discovery was made by 48 astronomers around the world who described the findings in five new papers in The Astrophysical Journal and the Publications of the Astronomical Observatory of Japan.

The finding was based on data taken with the Hyper Suprime-Cam, a “cutting-edge instrument” at the Subaru Telescope at the National Astronomical Observatory of Japan, in Hawaii, which the researchers combined with readings from three more powerful telescopes around the world.

Quasar Theory

The newly-discovered black holes are quasars, which shoot out matter in powerful jets. The researchers are hoping that more datagathering and analysis will shed light onto how some of the earliest quasars in the universe formed.

“The quasars we discovered will be an interesting subject for further follow-up observations with current and future facilities,” said Yoshiki Matsuok, a researcher at Ehime University who worked on the discovery. “We will also learn about the formation and early evolution of [super massive black holes], by comparing the measured number density and luminosity distribution with predictions from theoretical models.”

Cryptocurrency Price Forecast: Trust Is Growing, But Prices Are Falling

Trust Is Growing…
Before we get to this week’s cryptocurrency news, analysis, and our cryptocurrency price forecast, I want to share an experience from this past week. I was at home watching the NBA playoffs, trying to ignore the commercials, when a strange advertisement caught my eye.

It followed a tomato from its birth on the vine to its end on the dinner table (where it was served as a bolognese sauce), and a diamond from its dusty beginnings to when it sparkled atop an engagement ring.

The voiceover said: “This is a shipment passed 200 times, transparently tracked from port to port. This is the IBM blockchain.”

Let that sink in—IBM.

Ripple Price Forecast: XRP vs SWIFT, SEC Updates, and More

Ripple vs SWIFT: The War Begins
While most criticisms of XRP do nothing to curb my bullish Ripple price forecast, there is one obstacle that nags at my conscience. Its name is SWIFT.

The Society for Worldwide Interbank Financial Telecommunication (SWIFT) is the king of international payments.

It coordinates wire transfers across 11,000 banks in more than 200 countries and territories, meaning that in order for XRP prices to ascend to $10.00, Ripple needs to launch a successful coup. That is, and always has been, an unwritten part of Ripple’s story.

We’ve seen a lot of progress on that score. In the last three years, Ripple wooed more than 100 financial firms onto its.

On the whole, cryptocurrency prices are down from our previous report on cryptos, with the market slipping on news of an exchange being hacked and a report about Bitcoin manipulation.

However, there have been two bright spots: 1) an official from the U.S. Securities and Exchange Commission (SEC) said that Ethereum is not a security, and 2) Coinbase is expanding its selection of tokens.

Let’s start with the good news.

Another Crypto Hack Derails Recovery
Since our last report, hackers broke into yet another cryptocurrency exchange. This time the target was Bithumb, a Korean exchange known for high-flying prices and ultra-active traders.

While the hackers made off with approximately $31.5 million in funds, the exchange is working with relevant authorities to return the stolen tokens to their respective owners. In the event that some is still missing, the exchange will cover the losses. (Source: “Bithumb Working With Other Crypto Exchanges to Recover Hacked Funds,”.

Cryptocurrency News: Bitcoin ETFs, Andreessen Horowitz, and Contradictions in Crypto

Cryptocurrency News
This was a bloody week for cryptocurrencies. Everything was covered in red, from Ethereum (ETH) on down to the Basic Attention Token (BAT).

Some investors claim it was inevitable. Others say that price manipulation is to blame.

We think the answers are more complicated than either side has to offer, because our research reveals deep contradictions between the price of cryptos and the underlying development of blockchain projects.

For instance, a leading venture capital (VC) firm launched a $300.0-million crypto investment fund, yet liquidity continues to dry up in crypto markets.

Another example is the U.S. Securities and Exchange Commission’s.

Cryptocurrency News & Market Summary
Investors finally saw some light at the end of the tunnel last week, with cryptos soaring across the board. No one quite knows what kicked off the rally—as it could have been any of the stories we discuss below—but the net result was positive.

Of course, prices won’t stay on this rocket ride forever. I expect to see a resurgence of volatility in short order, because the market is moving as a single unit. Everything is rising in tandem.

This tells me that investors are simply “buying the dip” rather than identifying which cryptos have enough real-world value to outlive the crash.

Although cryptocurrency prices were heating up last week (Bitcoin, especially), regulators poured cold water on the rally by rejecting calls for a Bitcoin exchange-traded fund (ETF). This is the second time that the proposal fell on deaf ears. (More on that below.)

Crypto mining ran into similar trouble, as you can see from Advanced Micro Devices, Inc.‘s (NASDAQ:AMD) most recent quarterly earnings. However, it wasn’t all bad news. Investors should, for instance, be cheering the fact that hedge funds are ramping up their involvement in cryptocurrency markets.

Cryptocurrency News
Even though the cryptocurrency news was upbeat in recent days, the market tumbled after the U.S. Securities and Exchange Commission (SEC) rejected calls for a Bitcoin (BTC) exchange-traded fund (ETF).

That news came as a blow to investors, many of whom believe the ETF would open the cryptocurrency industry up to pension funds and other institutional investors. This would create a massive tailwind for cryptos, they say.

So it only follows that a rejection of the Bitcoin ETF should send cryptos tumbling, correct? Well, maybe you can follow that logic. To me, it seems like a dramatic overreaction.

I understand that legitimizing cryptos is important. But.

Boeing Is Prepping to Launch Astronauts to Space Station

Commercial Crew Program

SpaceX isn’t the only company attempting to revolutionize the way we send astronauts to space.

Boeing, the largest aerospace company in the world, is looking to send up its own take on a passenger spacecraft, which it calls the CST-100 Starliner, to the International Space Station. Boeing is planning to launch the capsule — uncrewed for now, as a test flight — on an Atlas 5 rocket as early as April, according to NASA.

Starliner

Boeing’s commercial spacecraft shares similarities with SpaceX’s Crew Dragon: it can seat a crew of seven, be operated from a central control panel, dock autonomously with the ISS, and can also be reused multiple times.

Boeing’s Starliner is the result of a $4.2 billion contract signed with NASA in 2014 under the Commercial Crew Program. SpaceX signed a very similar contract for its Crew Dragon mission at the same time, although it paid SpaceX just $2.4 billion.

Race to the ISS

SpaceX successfully launched its passenger spacecraft to the ISS on Saturday, becoming the first ever private American spacecraft to do so. It also marked the first time astronauts launched into space from American soil since the end of NASA’s Space Shuttle program in 2011.

Boeing has tests to complete before it takes off.

“There still are many critical steps to complete before launch and while we eagerly are anticipating these launches, we will step through our test flight preparations and readiness reviews,” Kathy Lueders, Commercial Crew Program manager at NASA said in an official update.

SpaceX is planning a crewed test flight in July of this year. Boeing wants to do the same only a month later — and its first pilots are already on stand-by.

China: New “Artificial Sun” Will Be Completed This Year

A Chinese official claims the nation is poised to wrap up construction on the HL-2M tokamak, a new

On the Horizon

In November, Chinese researchers announced that the Experimental Advanced Superconducting Tokamak (EAST) reactor — an “artificial sun” designed to mimic the nuclear fusion process the real Sun uses to generate energy — had hit a milestone by achieving an electron temperature of 100 million degrees Celsius.

Now, officials are saying they believe they’ll wrap up construction on a new artificial sun this year, and they claim this device will be able to hit a milestone in ion temperature — putting us one step closer to harnessing the power of nuclear fusion.

Hot Tech

On Sunday Duan Xuru, an official at the China National Nuclear Corporation, announced during the annual session of the Chinese People’s Political Consultative Conference that engineers would wrap up construction on the nation’s HL-2M Tokamak in 2019.

“The artificial sun’s plasma is mainly composed of electrons and ions,” Duan told the media, according to the Global Times, “and the country’s existing Tokamak devices have achieved an electron temperature of over 100 million degrees C in its core plasma, and an ion temperature of 50 million C, and it is the ion that generates energy in the device.”

Tokamak

According to Duan, the HL-2M Tokamak will be able to achieve an ion temperature of 100 million degrees Celsius, about seven times hotter than the real Sun’s ion temperature. This meets meeting what the Global Times calls “one of the three challenges to reach the goal of harnessing the nuclear fusion.”

If he’s right, the device could serve as a template for future nuclear fusion reactors, bringing the dream of unlimited clean energy one step closer to reality.
