World’s first 3D printed bridge looks pretty cool — The world’s first 3D-printed steel bridge, a 12.19m stainless steel structure titled simply The Bridge, looks tantalizingly otherworldly thanks to its unique construction methods. It is now ready for installation in Amsterdam following its ongoing week on show at the Dutch Design Week from October 20-28.

Creating the first Quantum Internet — Scientists in Chicago are trying to create the embryo of the first quantum internet. If they succeed, the researchers will produce one, 30-mile piece of a far more secure communications system with the power of fast quantum computing.
The key has been the realisation of an unused, 30-mile-long fibre-optic link connecting three Chicago-area research institutions: Argonne National Lab, Fermi Lab and the University of Chicago. This led to the idea to combine efforts and use the link for what they call the Chicago Quantum Exchange.

Intel’s latest consumer CPU is close to a revolution — The 9th-Gen i9 9900K retails for US$859, has 8 cores that can run up to 16 threads concurrently, and it’s one of the first CPUs to ship with a turbo frequency of 5GHz. It isn’t just fast, it’s coming close breaking a long believed theoretical limit. 5GHz has been something of a pipe dream for many years, posing a theoretical barrier that most CPUs could not surpass without significant tweaking to the fundamental design of processors. But Intel shipped a limited edition i7-8086K earlier this year with the same clock speed, while AMD shipped the FX 9590 back in 2013 (although this was largely considered a failure).
~ Gassin’ the GigaHertz all right.
Tiny PC a powerhouse — You’ll soon be able to get Hardkernel’s ODROID-H2 — a 110mm² motherboard packing a full, x86-64 Intel CPU that can not only run Windows 10, but power two 4K displays.
The guts of the ODROID-H2 is Intel’s quad-core J4105 processor, clocked at 2.3GHz and based on the Goldmont Plus architecture. This isn’t some cut-down hardware, but a full, x86-64 chip that can run anything a regular desktop can. And it weighs just 320 grams!
~ Boo-yah! Well, I guess we should be surprised going by how much wallop the latest smartphones pack.
Device pulls drink water from the air — A new device that sits inside a shipping container can use clean energy to almost instantly bring clean drinking water anywhere: the rooftop of an apartment building in Nairobi, a disaster zone after a hurricane in Manila, or a rural village in Zimbabwe. And it does it by pulling water from the air. The design, from the Skysource/Skywater Alliance, just won US$1.5 million in the Water Abundance XPrize. The competition, launched in 2016, asked designers to build a device that could extract at least 2000 litres of water a day from the atmosphere (enough for the daily needs of around 100 people), use clean energy, and cost no more than 2 cents a litre. That challenge has now concluded.
~ Yeah, you thought it was a roof and guttering, didn’t you? But this thing even works where there is no rainfall.
New material can raise the efficiency of solar power — A composite of tungsten and zirconium carbide (both of which have the extremely high melting points of 3,700K) conduct heat extremely well, and neither of them expands or softens much under these conditions, meaning they would hold up better to the mechanical stresses. This could help, eventually, to lower the price of solar concentration arrays because it’s possible to use much less of it to build a heat exchanger.
~ The real hurdle is to come up with good enough, affordable batteries so that solar power can be used overnight.
Not exercising at all is worse for your health than smoking, diabetes and heart disease — Exercise helps you live longer [and this is, after all, a column about the future]. But a new study published in the journal JAMA Network Open goes further, finding that a sedentary lifestyle is worse for your health than smoking, diabetes and heart disease. There appears to be no limit to the benefit of aerobic exercise. Researchers have always been concerned that “ultra” exercisers might be at a higher risk of death, but the study found that not to be the case.
~ Of course, exercising on an active battlefield still poses potentially life-shortening risks no matter how fast you can run while carrying a load.
Archaeologists have discovered two previously unknown forms of spearpoint technology at a site in Texas — The triangular blades appear to be older than the projectile points produced by the Paleoamerican Clovis culture (once thought of as the earliest example of human activity in North America). This observation is complicating our understanding of how the Americas were colonised – and by whom.
~ And that’s the real point of the spearpoints.
Fearsome marsupial ‘lion’ of Australia disappeared 35,000 years ago, but why? — New research suggests it was climate change rather than human activity that caused Thylacoleo carnifex to become extinct. For millions of years, Thylacoleo carnifex ruled the forests of Australia, but the predatory species disappeared around 35,000 to 45,000 years ago. Humans first appeared in Australia around 60,000 years ago, leading scientists to wonder if humans were somehow responsible – hardly an outrageous suggestion, given our track record.
But this research helps demonstrate that even the fiercest predators [hint hint] can succumb to climate change.
