New iphones, ipads, and Apple TVS September 9th September is upon us, and that means a major Apple event is right around the corner.

But given the fact that the Apple TV has received so much attention in the rumor mill this year,
By and large, the next versions of the iphone are being referred to as the sand s Plus. Given Apple previous use of the ick-tockmodel, that certainly makes sense.

Not only is this giant ipad slated to sport a 2048×2732 resolution but it will also have a pressure sensitive stylus to boot.
If the rumors are true, this premium device will clearly be targeting the professional market.

#Terahertz breakthrough allows for ultrafast wireless communications A collaboration between US and Japanese researchers, have developed a key component
in order to enable wireless communications which operate up to 100x faster than current generation routers. Current wireless communications operate at microwave frequencies,
however as the demand for faster speeds and larger bandwidths increases, scientists are looking for ways to alleviate the communication bottleneck.
Between the microwave and infrared part of the electromagnetic spectrum lies an appealing candidate: Terahertz (THZ) radiation.
THZ waves were utilized previously for the wireless data transmission world record, whereby a team of researchers showed local data transmission could be up to 100gbit/s. However, for any real world system,
electronic components are required which perform common functions akin to our regular communication technology; such as transmission, multiplexing, demultiplexing,
and demultiplex signals (separate out the multiple independent data streams for further processing). This technique permits the transfer of the masses of data around the internet, TV,
etc. whereby a vast number of data channels are carried over a single optical fiber, wirelessly or copper cable.
However, multiplexing and demultiplexing of the much faster THZ signals remains an unaddressed challenge; despite the importance of such capabilities for broadband networks.

#Microfluidic cooling yields huge performance benefits in FPGA processors As microprocessors have grown in size and complexity,
Intel CPU clock speeds have remained mostly flat for years, while AMD FX-9590 and its R9 Nano GPU both illustrate dramatic power consumption differences as clock speeds change.
One of the principle barriers to increasing CPU clocks is that it extremely difficult to move heat out of the chip.
New research into microfluidic cooling could help solve this problem, at least in some cases. Microfluidic cooling has existed for years;
we covered IBM Aquasar cooling system back in 2012, which uses microfluidic channels tiny microchannels etched into a metal block to cool the Supermuc supercomputer.
Now, a new research paper on the topic has described a method of cooling modern FPGAS by etching cooling channels directly into the silicon itself.
Previous systems, like Aquasar, still relied on a metal transfer plate between the coolant flow and the CPU itself.
and CPUS aren very good at spreading that heat out across the entire surface area of the chip.
This is why Intel specifies lower turbo clocks if youe performing AVX2-heavy calculations. By etching channels directly on top of a 28nm Altera FPGA, the research team was able to bring cooling much closer to the CPU cores
and eliminate the intervening gap that makes water-cooling less effective then it would otherwise be.
an associate professor and ON Semiconductor Junior Professor in the Georgia Tech School of Electrical and Computer engineering. e have eliminated the heat sink atop the silicon die by moving liquid cooling just a few hundred microns
but whether or not it could ever scale to consumer hardware is a very different question.
As the feature image shows, the connect points for the hardware look decidedly fragile and easily dislodged or broken.
The amount of effort required to etch a design like this into an Intel or AMD CPU would be non-trivial,
and the companies would have to completely change their approach to CPU heat shields and cooling technology.
Still, technologies like this could find application in HPC clusters or any market where computing power is at an absolute premium.
Removing that much additional heat from a CPU die would allow for substantially higher clocks even with modern power consumption scaling n
