But while screening can be extremely helpful, it also carries some risks. Here’s what you need to know about lung cancer screenings.

How does lung cancer screening work?

Currently, there’s only one recommended screening test for lung cancer: low-dose computer tomography (low-dose CT scan). This test creates images of the inside of the body — or in this case, the lungs — using low doses of radiation.

Even after the rise of #MeToo, disbelief is all too commonly the outcome of reporting sexual harassment and assault. Many women describe the experience of having men they trust doubt the severity and frequency of what they have to put up with as painful as the experience itself. Advertising agency Ogilvy wondered if men would be more likely to pay attention to smart clothing than the women in their lives, so they created dresses that keep a record of events.

The dresses have sensors sewn into them that record contact and pressure. Any impact on a sensor is sent via wifi to a computer that not only keeps track of what is happening but translates it into a heat map of location and time of contact with the body.

When three women wore the dresses to a Brazilian party, they were touched non-consensually 157 times in less than four hours – a rate of more than once every five minutes per woman. As the video below shows, this is despite repeatedly telling the men involved to stop.

New research reveals why the “supermaterial” graphene has not transformed electronics as promised, and shows how to double its performance and finally harness its extraordinary potential.

Graphene is the strongest material ever tested. It’s also flexible, transparent and conducts heat and electricity 10 times better than copper.

After graphene research won the Nobel Prize for Physics in 2010 it was hailed as a transformative material for flexible electronics, more powerful computer chips and solar panels, water filters and bio-sensors. But performance has been mixed and industry adoption slow.

There are huge multi-trillion dollar opportunities developing with Space and the further evolution of the internet.

Space launch and space satellites were already a $300 billion per year industry. Cloud Computing is a $200 billion market in 2018. Global Internet services is a $600 billion market. The Global IT market is nearing $5 trillion in size. The global Auto industry is $2 trillion in size. The Global supply chain industry is $40 trillion in size.

Space launch, Internet and communication, Internet of Things, Space mining, Space Colonization will each become future multi-trillion markets. Those that are already trillion dollar markets will become even larger.

This is a critical step along the way to functional quantum computers that can achieve problems far beyond the capacity of traditional systems.

The Silicon Quantum Electronics Workshop will have 200 researchers sharing insights and technology advancements about building the world’s first silicon quantum computer.

NSW university has set up a Quantum Computer Company

Silicon Quantum Computing Pty. Ltd. (SQC) is working to create and commercialize a quantum computer based on world-leading intellectual property acquired from the Australian Centre of Excellence for Quantum Computation and Communication Technology (CQC2T). We have set ourselves a bold ambition: to develop a 10-qubit quantum integrated circuit prototype in silicon by 2022.

Ground control to major Jeff (Bezos).

Amazon Web Services (AWS), the company’s cloud computing arm, just announced a new offering aimed at satellite operators.

The news: At its annual re: Invent conference in Seattle this week, the web giant unveiled a service that lets owners of satellites rent time on Amazon-managed ground stations to send and receive data from orbit. The service, called AWS Ground Station, works in much the same way as Amazon’s well-established business for tapping computing capacity via the cloud.

Electrical engineers in the accelerator physics group at TU Darmstadt have developed a design for a laser-driven electron accelerator so small it could be produced on a silicon chip. It would be inexpensive and with multiple applications. The design, which has been published in Physical Review Letters, is now being realised as part of an international collaboration.

Being able to control electronic systems using light waves instead of voltage signals is the dream of physicists all over the world. The advantage is that electromagnetic light waves oscillate at petaherz frequency. This means that computers in the future could operate at speeds a million times faster than those of today. Scientists at Friedrich-Alexander University (FAU; Erlangen-Nurenberg, Germany) have now come one step closer to achieving this goal as they have succeeded in using ultra-short laser impulses to precisely control electrons in graphene. The scientists published their results in Physical Review Letters.

Current control in electronics that is one million times faster than in today’s systems is a dream for many. Ultimately, current control is one of the most important components as it is responsible for data and signal transmission. Controlling the flow of electrons using light waves instead of voltage signals, as is now the case, could make this dream a reality. However, up to now, it has been difficult to control the flow of electrons in metals as metals reflect light waves and the electrons inside them cannot be influenced by these light waves.
