Stem cells used to regenerate the external layer of a human heart

Posted by in categories: biotech/medical, engineering

A process using human stem cells can generate the cells that cover the external surface of a human heart — epicardium cells — according to a multidisciplinary team of researchers.

“In 2012, we discovered that if we treated human stem cells with chemicals that sequentially activate and inhibit Wnt signaling pathway, they become myocardium muscle cells,” said Xiaojun Lance Lian, assistant professor of biomedical engineering and biology, who is leading the study at Penn State. Myocardium, the middle of the heart’s three layers, is the thick, muscular part that contracts to drive blood through the body.

The Wnt signaling pathway is a group of signal transduction pathways made of proteins that pass signals into a cell using cell-surface receptors.

Fast Radio Bursts from Extragalactic Light Sails

Posted by in categories: alien life, engineering

Abstract: We examine the possibility that Fast Radio Bursts (FRBs) originate from the activity of extragalactic civilizations. Our analysis shows that beams used for powering large light sails could yield parameters that are consistent with FRBs. The characteristic diameter of the beam emitter is estimated through a combination of energetic and engineering constraints, and both approaches intriguingly yield a similar result which is on the scale of a large rocky planet. Moreover, the optimal frequency for powering the light sail is shown to be similar to the detected FRB frequencies. These ‘coincidences’ lend some credence to the possibility that FRBs might be artificial in origin. Other relevant quantities, such as the typical mass of the light sail, and the angular velocity of the beam, are also derived. By using the FRB occurrence rate, we infer upper bounds on the rate of FRBs from extragalactic civilizations in a typical galaxy. The possibility of detecting fainter signals is briefly discussed, and the wait time for an exceptionally bright FRB event in the Milky Way is estimated.

Microsoft looks to tap quasiparticles to bring about a scalable quantum computer

Posted by in categories: computing, engineering, quantum physics

Microsoft has been on a quest to build the holy grail of computers for over a decade, dumping tons of money into researching quantum computing and the company says they are ready to transition over to the engineering phase of their endeavor. At least that’s what MS executive Todd Holmdahl aims to accomplish by developing the hardware and software to do so.

Could We Marsiform Ourselves?

Posted by in categories: engineering, environmental

Changing another world to support Earth life is called terraforming. But maybe it’s a better idea to just change Earth life to live on other worlds.

Mixed Reality will be most important tech of 2017

Posted by in categories: augmented reality, engineering, information science, quantum physics, virtual reality

Quantum will be the most important technology in 2017; as it will touch everything as well as change everything. Until we see a better integration of AR in Enterprise Apps, platforms, and published services; AR like VR will remain a niche market gadget.

I do know companies like Microsoft, SAP, and Oracle have been looking at ways to leverage AR in their enterprise platforms and services such as ERP and CRM as well as Big Data Analytics; however, to see the volume of sales needed to make VR or AR have staying power on a large scale; the vendors will need to it a pragmatic useful device on multiple fronts. And, yes it is great that we’re using VR and AR in healthcare, defense, engineering, and entertainment (includes gaming); we just need to make it an every consumer device that people canot live with out.


2016 has been a remarkable year that’s brought continued growth and awareness to the worlds of Augmented, Virtual and Mixed Reality. Set to become a $165 Billion dollar industry by 2020, there’s still a common question that lingers among many newcomers trying to understand this fast moving digital phenomena we are just beginning to watch evolve: What’s the difference between them and how will it impact the digital world as I currently know it?

The Future Of Encryption

Posted by in categories: business, cybercrime/malcode, encryption, engineering, internet, quantum physics

QC in the mainstream is definitely viable less than 7 yrs. and possible within 5 yrs. However, I have a friend who even believes we’re looking at 3 years.


Internet security, once considered to be strictly in the domain of the wonkiest tech experts, has become central to public discourse over the past year. Besides the attacks on the DNC, even tech savvy business like Snapchat, Oracle and Verizon Enterprise Solutions have had significant breaches in the last year.

For the most part, these attacks were preventable. Often, hackers use a technique called social engineering, to trick people into allowing them into a system. Other times, they exploit a vulnerability in software to give them access to confidential data. In most cases, more stringent procedures can prevent attacks.

NASA Just Released Its Incredibly Cool Concept for Houses on Mars

Posted by in categories: engineering, habitats, space

NASA researchers have a lot of problems to work through if they want astronauts to one day set foot on Mars. One of the biggest hurdles is where these early pioneers will sleep and live, and after a day of brainstorming, engineers might have come up with a solution – a conceptual ‘ice home’ design.

Yup, NASA is looking into creating inflatable domes covered in ice for astronauts to live and work in, providing them with protection from extreme temperatures and high-energy radiation.

“After a day dedicated to identifying needs, goals, and constraints we rapidly assessed many crazy, out of the box ideas and finally converged on the current Ice Home design, which provides a sound engineering solution,” said senior systems engineer Kevin Vipavetz, from NASA’s Langley Research Centre in Virginia.

The Science and Engineering of Quantum Dot Lasers

Posted by in categories: engineering, quantum physics, science

Since their development in 1960, lasers have become an indispensable tool supporting our modern society, finding use in fields such as medicine, information, and industry. Thanks to their compact size and energy efficiency, semiconductor lasers are now one of the most important classes of laser, making possible a diverse range of applications. However, the threshold current of a typical semiconductor laser—the minimum electrical current required to induce lasing—increases with temperature. This is one of a number of disadvantages that can be overcome by using quantum dot lasers. Professor Yasuhiko Arakawa of the Institute of Industrial Science at the University of Tokyo has been researching quantum dot lasers for about 35 years, from their conception to commercialization.

Sunlight is composed of light of various colors. The property that determines the color of light is its wavelength, or in other words, the distance between two successive wave peaks or troughs. The location of the peaks and troughs in the waveform is known as its phase. As a laser emits light waves in a uniform phase at the same wavelength, the light can be transmitted as a beam over long distances at high intensity.
