A Stem Cell Patch Could Heal Hearts Damaged By Cardiac Arrest

The Beat Goes On

The human body has an extraordinary capacity to heal itself: livers can regenerate when damaged, one kidney can learn to do the job of two, and our skin is constantly working to protect us from scratches and cuts that could expose us to harmful pathogens.

One of our most vital organs, however, can’t heal quite so well. When our hearts are damaged — by disease or injury — the tissue can’t regenerate very well, or very fast. After a major heart attack, for instance, billions of heart muscle cells may be lost forever. This loss weakens the heart and often ends up leading to conditions like congestive heart failure, or scar tissue build-up, which can be fatal.

Currently, the only option for a patient with a damaged or diseased heart is receiving a heart transplant. Donor hearts have to come from people who had healthy hearts before they died — which usually means patients who were fairly young and died in accidents, or from injuries or illnesses that didn’t affect their heart. Patients who are waiting for a donor match to receive a transplant can be waiting a very long time.

At the time of publication, there were nearly 4,000 people in the U.S. waiting for a heart, according to the Organ Procurement and Transplantation Network. Some of them will die on the waitlist before a match can be found.

Mend a Broken Heart

But a team of researchers at the University of Cambridge’s Stem Cell Institute in the U.K. is developing an innovative way to repair heart tissue. The team’s solution doesn’t require a donor heart at all — instead, they’ve used stem cells to grow live patches of heart muscle in the lab. These patches are just 2.5 square centimeters (0.5 square inches) but could potentially be a powerful tool to treat patients with heart failure.

“We believe that these patches will stand a much greater chance of being naturally assimilated into a patient’s heart,” says  Sanjay Sinha, a cardiologist at Addenbrooke’s Hospital in Cambridge, “[…] we’re creating fully functional tissue which already beats and contracts through combining all these different cell types which communicate with each other.”

While researchers have tried to inject stem cells directly into damaged heart tissue in the past, the technique didn’t prove particularly effective — mostly because the stem cells wind up getting lost in the bloodstream instead of staying in the heart muscle, where they’re needed.

These patches, on the other hand, are live, beating heart tissue that can be affixed to the organ like a scaffold. And, unlike a donor heart, a patient in need wouldn’t have to wait for a match to be found. Instead, the patches could be grown as-needed, and on-demand.

The scaffolding tissue will also be grown from the patient’s own cells — eliminating the need for a lifetime of immunosuppressants drugs and lowering the risk of organ rejection, two problems that transplant patients typically face.

Eventually, the University of Cambridge team hopes that the custom-made heart patch could be 3D-printed to perfectly fit the area of damaged muscle, then sewn onto the organ by a surgeon — while still an invasive procedure, one that much less involved than a total heart transplant. The biggest obstacle to that procedure will be ensuring that the electrical impulses that make the heart beat can be fully integrated with the patch.

Sinha’s team is close to getting their stem cell patches approved for animal trials. If the patches pass with flying colors, they could be ready for human clinical trials within five years.

Bacon? Cell Phones? It’s Rarely Just One Thing That Causes Cancer

How Complete Beginners are using an ‘Untapped’ Google Network to create Passive Income ON DEMAND

If experts are to be believed, beer causes cancer. So does bacon. Cellular phones could cause cancer, but no one is really sure. So could the fluoride added to the water supply. Oh, and not exercising? Definitely causes cancer.

Fortunately, other things prevent it. Fruits and vegetables do a pretty good job. And so do nuts, according to Yale research published last week. Then there are the things that are murkier — beer could prevent cancer, but then again it could also cause it.

Headlines have been similarly contradictory. “Scientists have linked X to cancer.” We’ve seen it over and over and over. It’s an endless refrain, repeated more or less daily. Take a look at some of the highlights from just the last seven days:

Find this confusing? You’re not alone. And that’s all the more reason not to act on the advice of the latest headline.

Cancer is the second leading cause of death in America. If most headlines are to be believed, there is generally a single entity of a person’s lifestyle that, if altered in a specific way, can stave off the onset of the disease. However, decades of science have indicated that most cancers are complex diseases, caused by a combination of genetic and environmental factors — it’s rarely just one thing in a person’s life that can be blamed as the cause. 

Putting too much stock in these headlines means that you’re probably paying too much attention to an element of your lifestyle that ultimately doesn’t make much of a difference — and neglecting holistic advice that is actually proven to work.

In short: Anyone who says they have the answer — an answer — is lying.

At face value, the science doesn’t appear to offer much clarity. According to the American Cancer Society, there are more than 300 activities and substances that could cause cancer, and nearly the same number that could prevent it. It is virtually impossible to keep track of all these things, and frankly, it’s not even worth the effort, since so much of that advice is contradictory anyway.

Here’s the thing that scientists know about these studies that the average reader does not: Each study is a very small part of a much larger picture. Scientists come to a conclusion bound by a specific set of parameters that open the door to further experimentation. Maybe an initial study was done in mice — its conclusion could be interesting, but that doesn’t mean it’s ready to be applied to humans. Or perhaps scientists found that two entities have a relationship, but they don’t yet know what that relationship is (does one thing cause another? or is there a third thing that causes both?).

If research is going to change the advice that doctors give to patients, the studies need to be validated and their conclusions proven over and over. So ultimately, true scientific progress can be found in the summary of dozens, hundreds, or thousands of studies. The nuanced recommendations that doctors give take all this into account, and are determined by panels of medical professionals.

You know what’s not nuanced, and usually not written by a doctor? A headline.

When it comes to preventing your own death, you shouldn’t put your faith — and definitely not your fate — in the latest thing to pop up on your news feed that you half-read while riding the train.

So, which kinds of simplistic advice should you incorporate into a healthy lifestyle? Probably just the stuff you learned in elementary school: eat lots of fruits and vegetables, exercise, and listen to your doctor.

MWC 2018: World’s first streetlight powered smart cell lights up

Lighting up the IoT: Connected technology firm Ubicquia has shown off what it claims is the world’s first streetlight-powered smart cell, ahead of MWC 2018 in Barcelona.

The device, called Ubimetro, allows streetlights to become integrated components within a variety of IoT networks, using them both as power sources and transmission towers. It forms part of the company’s strategy to bring smart-city technology to the masses. 

Ubimetro consists of an omni-directional antenna and NEMA socket plug. Ubicquia said the device can work with an estimated 300 million streetlights across the globe.

Revolutionary tech

Using the new system, technology companies and city officials alike will be able to expand their IoT infrastructures using street furniture that is already integrated into the built environment worldwide. It can also improve the overall capacity and efficiency of these networks, claimed the company, and be used in a number of vertical applications.

Under the hood is an FSM-based architecture developed by American chipmaker, Qualcomm. This can support mobile broadband, fibre, ethernet, broadband power line, and wireless backhaul.

The Florida-based tech firm said the device also comes with LAA and V-RAN technologies. These will be paramount in the development of 5G networks, they said.

In the US last year, AT&T struck a deal with GE to begin installing Current CityIQ sensors in streetlights around the US. Its aim was not just to provide smart lighting, but also to monitor traffic, parking, air quality, and extreme weather, and even listen for gunshots.

Transforming smart cities

Ubicquia CEO, Ian Aaron, said the firm is on a mission to revolutionise networking technology. “Our goal was to bring Ubimetro to market at a price point that would make it more attractive for operators, utilities, municipalities, and tower companies to create ultra-dense small cell networks,” he said.

“By leveraging the streetlight infrastructure and our plug-and-play installation, Ubimetro is able to give mobile operators a dedicated host and self-managed network with one of the industry’s lowest total cost of ownership and fastest times to market.”

Tre Zimmerman, chief technology officer of Ubicquia, added that the company wants the device to become a core part of smart city developments all over the world. “We have overcome numerous design challenges to bring to market the first NEMA-socket-powered small cell that plugs into the top of a streetlight,” he said.

Zimmerman added: “Integrating fibre, ethernet, PLC, and wireless backhaul into Ubimetro means operators can deploy more quickly by leveraging a municipality’s or utility’s existing infrastructure.

“Ubimetro incorporates HeMS (HeNB Management System) software that provides operational, administration, maintenance, and provisioning [OAM & P] for the distributed HeNB devices.”

• Ubicquia will demonstrate the device at Mobile World Congress, which takes place from 26 February 26th to 1 March, in Barcelona.

Internet of Business says

The race to turn existing infrastructure assets into components of a variety of different IoT networks is on. Streetlights no longer just light up our cities and road networks, but may soon also provide illuminating data. By seeing them as powered towers that are located in every town across the globe, Ubicquia and others are helping to make our cities smarter and more efficient. Plus, the plug-and-play aspect of this new technology means that new types of network can be created on demand.

911 Wasn’t Set Up With Cell Phones In Mind. Google Could Change that.

When the 911 emergency number was set up in 1968, there was no way to know how cellphones would change the way people use the service. Today, it’s still difficult for operators to pinpoint the exact location of callers to send out help – but Google could change all that.

The search giant has been testing out a way to use the technology that identifies the user’s location in Google Maps to help out the emergency services. As reported by the Wall Street Journal, a sample of 911 calls made using Android phones over the course of December 2017 and January 2018 saw geolocation data sent directly to the operator.

Currently, carriers can detect the location of a device by triangulating their distance from several cell phone towers, but this isn’t particularly accurate.  The study found that Google’s data gave an average location estimate radius of 121 feet, whereas carrier data averaged out at 522 feet.

At present, it falls to the operator to find out the exact location emergency responders need to be sent to from the caller. Given that they might be flustered, or potentially in a place they’re not familiar with, this can be a difficult prospect.

In this kind of situation, a slight improvement on the response time can be life-saving. Research published by the Federal Communications Commission suggests that as many as 10,000 lives could be saved annually if emergency response times were improved by just one minute.

Google has had the technology to provide this service for some time – it was rolled out in the U.K. and Estonia in July 2016, according to a report from Ars Technica. Many feel uncomfortable with the idea of allowing their smartphone to track their location, but in emergency circumstances, it’s easy to see the benefits.

Facebook using 2FA cell numbers for spam, replies get posted to the platform

Facebook is reportedly spamming some users by text, using a cell number they provided only for use in two-factor authentication.

In common with many services, Facebook allows you to protect your account by requiring a code when you first login from a new device. That code is texted to a cell number you provide for the purpose – but a number of users have reported it being used without their permission for notifications about posts by friends …



Hyundai tests first autonomous fuel cell cars

South Korean car maker Hyundai has successfully tested what it claims are the world’s first self-driven fuel cell electric vehicles.

A fleet of the cars completed a self-driven, high-speed, 190-kilometre test drive from Seoul to Pyeongchang. The firm said this is the first time that “level 4 autonomous driving has been achieved with fuel cell electric cars”.

Level four autonomy is when vehicles are able to perform all safety-critical driving functions and monitor roadway conditions for an entire trip – one stage short of human-level safe driving in all road conditions.

In total, five cars completed the journey on 2 February. Three of them were based on the company’s fuel cell electric SUV NEXO technology, while the other two were Genesis G80 models.

The future of driving

Hyundai believes that fuel-cell cars could result in more efficient journeys at speed on domestic roads. During the test drive, the driverless cars travelled at between 100 km/h and 110 km/h, which is the maximum speed on Korean motorways.

The company claimed that the cars demonstrated its three visions for the future of driving: connected mobility, clean mobility, and freedom in mobility.

The vehicles “moved in response to the natural flow of traffic” on the highway, “executed lane changes and overtaking manoeuvres” and “navigated toll gates” using a wireless expressway payment system, said Hyundai.

The design of the cars is similar to the manufacturer’s mass-produced models, but they’re packed with cameras and a LIDAR system, which uses a laser to judge distances.

The cars use GPS technology and a range of other sensors to recognise other vehicles, make accurate judgements at junctions, navigate through toll gates, and identify different locations.

Jinwoo Lee, head of the intelligent safety technology centre at Hyundai, said the firm is working to “provide the highest level of safety combined with a high standard of convenience that our customers expect”.

Passengers also gain access to a system called “Home Connect”, which allows them to control IoT devices via their smartphones. Hyundai plans to release this system over the next few months.

Assault on batteries?

Autonomous vehicles need a lot of power, and Hyundai believes that fuel cell technology is the answer. The firm said the cars can drive 600 km on a single charge.

Fuel cell technology produces electricity by causing a reaction between hydrogen and oxygen, with environmentally friendly emissions of warm air and water. However, the industrial production of hydrogen can be carbon intensive, despite being the most abundant chemical substance in the universe. 

Internet of Business says

The combination of sustainable development, fuel efficiency, and minimum environmental impact will be critical to the future development of autonomous vehicles.

• Hyundai has yet to announce when its fuel cell electric vehicles will be available in the West.
