Scientists are planning to create a network in the Chicago area tapping the principles of quantum physics. The idea is to prove that quantum physics could provide the basis for an unhackable internet.

This, they say, could have wide-ranging impact on communications, computing and national security.

The quantum network development, supported by the US Department of Energy (DOE), will stretch between the DOE’s Argonne National Laboratory and Fermi National Acceleratory Laboratory, a connection that is said will be the longest in the world to send secure information using quantum physics.

A small device that contains human cells in a 3D matrix represents a giant leap in the ability of scientists to test how those cells respond to stresses, drugs and genetic changes. About the size of a thumb drive, the devices are known as tissue chips or organs on chips.

A series of investigations to test tissue chips in microgravity aboard the International Space Station is planned through a collaboration between the National Center for Advancing Translational Sciences (NCATS) at the National Institutes for Health (NIH) and the Center for the Advancement of Science in Space (CASIS) in partnership with NASA. The Tissue Chips in Space initiative seeks to better understand the role of microgravity on human health and disease and to translate that understanding to improved human health on Earth.

“Spaceflight causes many significant changes in the human body,” said Liz Warren, associate program scientist at CASIS. “We expect tissue chips in space to behave much like an astronaut’s body, experiencing the same kind of rapid change.”

In this video, we’ll be discussing the gap between computing performance and memory and how this ‘memory wall’ is to be demolished.

[0:25–7:00] Starting off we’ll look at, current different types of memory (SRAM, DRAM, NAND,…) and what their use cases and tradeoffs are. As well as, new types of memory that will break current paradigms, such as Optane memory and how all these types of memory can work together to yield performance boosts.

[7:00–9:40] Following that we’ll discuss, improving data transfer mediums and protocols and their effect on decreasing the memory gap.

We humans are intelligent, other living species are also intelligent but we build bridges and cars, we describe the universe and develop several languages while other species don’t. Well it seems the reason is that: we have a different hardware.

Neurons in human and rat brains carry electrical signals in different ways, scientists find.

Scientists in Australia have for the first time demonstrated the protection of correlated states between paired photons—packets of light energy—using the intriguing physical concept of topology. This experimental breakthrough opens a pathway to build a new type of quantum bit, the building blocks for quantum computers.

The research, developed in close collaboration with Israeli colleagues, is published today in the prestigious journal, Science, a recognition of the foundational importance of this work.

“We can now propose a pathway to build robust entangled states for logic gates using protected pairs of photons,” said lead author Dr. Andrea Blanco-Redondo at the University of Sydney Nano Institute.

This video is the fourth in a multi-part series discussing computing. In this video, weíll be discussing computing performance and efficiency as well as how the computer industry plans on maximizing them.

[0:25–1:55] Starting off we’ll look at, how computing performance is measured and its rate of increase since the mid-1900s.

[1:55–8:05] Following that we’ll discuss, new classical computing paradigms that will push the computer industry forward past 2020. These paradigm shifts are 3D integrated circuits and the use of new materials such as graphene.

[8:05–10:15] To conclude we’ll summarize and wrap up many of the concepts we’ve discussed over this and the past few videos in this series!

If you haven’t heard, universities around the world are offering their courses online for free (or at least partially free). These courses are collectively called MOOCs or Massive Open Online Courses.

In the past six years or so, over 800 universities have created more than 10,000 of these MOOCs. And I’ve been keeping track of these MOOCs the entire time over at Class Central, ever since they rose to prominence.

In the past four months alone, 190 universities have announced 600 such free online courses. I’ve compiled a list of them and categorized them according to the following subjects: Computer Science, Mathematics, Programming, Data Science, Humanities, Social Sciences, Education & Teaching, Health & Medicine, Business, Personal Development, Engineering, Art & Design, and finally Science.
