Multiband tunable antennas are a critical part of many communication and radar systems. New research by engineers at the University of Bristol has shown significant advances in antennas by using optically induced plasmas in silicon to tune both radiation patterns and operation frequency.

Conventional antenna tuning is performed with diodes or Micro-Electro-Mechanical Systems (MEMS) switches. However, these approaches have significant drawbacks as systems become more complex and move to higher frequencies, which is anticipated for 5G systems.

The first paper, published in IET Optoelectronics, co-authored by Dr Chris Gamlath, Research Associate in RF Engineering during his PhD, shows how a silicon superstrate placed over a slotted microstrip patch can be used to tune radiation patterns.

“If something goes wrong, I can just chop off that part of the skin.” Josiah Zayner took a swig from his beer and squinted into the spotlight. He was already kind of drunk. He also hadn’t bothered to write a speech. Tattooed and heavily pierced with a shock of blue-gray hair, he shuffled around uneasily on stage. But 150-odd people had flown in from around the country to hear him speak—the mad pirate-king of biotech. “It all is coming from my heart,” he said, choking up a little. “Everything you’re going to hear today is me to the core.” Advertisement Zayner’s audiencesat in the fashionably…

All Those in Favor of Using Real World Evidence, Say Aye!

Medical Devices are used in the real world every day, so shouldn’t they be tested in the real world? You would think so. But the FDA hasn’t necessarily been of that mindset — until now.

A controversial plan to cool down the planet by artificially simulating volcanic eruptions could have disastrous consequences for Earth—yet there are no laws or regulations to stop any country or private company from deploying such technology.

Solar geoengineering is one of the proposed ways to artificially reduce global temperatures. It is often seen as one of the most extreme options—but also potentially one of the most effective. It involves injecting aerosols into the atmosphere. When the gas combines with oxygen, droplets of sulfuric acid form. These droplets reflect sunlight away, cooling the planet in the process. All good in theory, but the consequences of solar geoengineering are largely unknown.

In a study published in Nature Communications, scientists led by Anthony Jones, from the University of Exeter, U.K., have now examined what would happen if solar geoengineering was used in the Northern Hemisphere to try to prevent global warming and the extreme weather that goes with it—in this case tropical cyclones.

With everyone from Elon Musk to MIT to the US Department of Defense researching brain implants, it seems only a matter of time before such devices are ready to help humans extend their natural capabilities.

Now, a professor from the University of Southern California (USC) has demonstrated the use of a brain implant to improve the human memory, and the device could have major implications for the treatment of one of the US’s deadliest diseases.

Dong Song is a research associate professor of biomedical engineering at USC, and he recently presented his findings on a “memory prosthesis” during a meeting of the Society for Neuroscience in Washington D.C. According to a New Scientist report, the device is the first to effectively improve the human memory.

A team of scientists at the University of California San Diego led by biologist Nan Hao have combined engineering, computer science, and biology technologies to decode the molecular processes in cells that influence aging.

South Korea is ‘almost 100 per cent certain’ that North Korean hackers have stolen the blueprints for their warships and submarines.

The despotic regime is thought to have taken the documents after hacking into Daewoo Shipbuilding & Marine Engineering Co Ltd’s database in April last year.

North Korea has often been implicated in cyber attacks in South Korea and elsewhere but Pyongyang has either ignored or denied accusations of hacking.

I was thinking about this thing, and the one in Iceland. Maybe we could build giant blimps in the atmosphere of Venus, it would carry that machine on its belly, and on the back of the blimp super advanced solar panels. Then inside of the blimp the CO2 could be mixed into liquid crystals or something like that and be dropped like rain down on the surface, to eventually terraform it.

Global Engineering — a phrase that describes steadying the world’s climate with technical solutions. A Swiss company has received EU funding to develop a machine that captures CO2. Can it really make a difference?

Science fiction is the siren song of hard science. How many innocent young students have been lured into complex, abstract science, technology, engineering, or mathematics because of a reckless and irresponsible exposure to Arthur Clarke at a tender age? Yet Arthur Clarke has a very famous quote: “Any sufficiently advanced technology is indistinguishable from magic.”

It’s the prospect of making that… ahem… magic leap that entices so many people into STEM in the first place. A magic leap that would change the world. How about, for example, having humanoid robots? They could match us in dexterity and speed, perceive the world around them as we do, and be programmed to do, well, more or less anything we can do.

Such a technology would change the world forever.

Ray Kurzweil is director of engineering at Google but he is better known for writing best-selling books outlining the future of artificial intelligence.

He has made 147 predictions on the future of technology including the ubiquity of wearable devices and the move from desktops and laptops to smartphones and tablets. In fact, his prediction rate has been rated 86 per cent accurate.

With this in mind, fans were excited to see Kurzweil answer their questions in a live streaming interview session last week where he elaborated on his predictions.
