The new Dick Tracy watch will keep time and make calls

Of all the pieces of pop culture “spy gear” that have been dreamed up over the years, one of the most iconic is the 2-way wristwatch radio used by comic-strip detective Dick Tracy. Well, if a just-launched Indiegogo campaign is successful, you’ll soon be able to get one that actually makes calls. read more

Water-cooling systems have long been used to keep computers from overheating, but how do you scale that up for huge data centers? According to Microsoft, you drop the data center to the bottom of the ocean. As the second phase of its Project Natick, the company has just deployed a data center in the frigid waters off Scotland’s Orkney Islands. read more

Geologists estimate that the Earth’s core is a sweltering 5,700 K (5,427° C, 9,800° F), putting it about on par with the surface of the Sun – and yet the inner core is a solid ball of iron. Why it doesn’t liquify is a bit of a mystery, but now a study from KTH Royal Institute of Technology puts forward a new theory, simulating how solid iron can remain atomically stable under such extreme conditions. read more

Leonardo Aerospace has taken the wraps off of its new expendable electronic countermeasures decoy for protecting large military transport aircraft. Billed as the first of its kind for transport protection, the BriteCloud 55-T is designed to hide the radar signature of large aircraft like the C27-J, C-130, KC-390, and A400M and confuse the targeting systems of radar-guided missiles. read more

Antibiotics are effective at killing bacteria (for now, at least), but they aren’t very picky, indiscriminately wiping out both good and bad bacteria. This can upset the fragile balance of your microbiome, which is increasingly being linked to general health and wellbeing. Now, researchers at Penn State have developed a new approach to make a drug that can single out a specific, opportunistic bacteria known as C. difficile. read more

Larry Page’s Kitty Hawk startup has been beavering away on several different personal flight projects, including a self-piloting, electric VTOL air taxi that can be used for Uber Elevate-style aerial commuting. The Silicon Valley company has also been working on something sportier – a single-seat multicopter fun machine called the Flyer. And today, the team released images and partial specs on what looks to be the final production design. read more

There’s a limited supply of donor human corneas, meaning that not everyone who needs an eyesight-saving transplant can get one. As a result, biosynthetic corneas have recently been developed. These could become quicker and easier to produce, as scientists have now successfully 3D-printed the things. read more

Glioblastoma is one of the most deadly forms of cancer. Affecting the brain, those unlucky enough to receive a diagnosis don’t have many treatment options – and usually a median life expectancy of just over a year. Now, researchers at MIT have developed nanoparticles that could provide hope, crossing the blood-brain barrier and delivering two types of drugs to fight tumors. read more

Though digital music accounts for much of what we now listen to, old school formats like vinyl and audio cassettes steadfastly refuse to disappear. The former is enjoying something of a healthy revival at the moment, but trying to find an album released on audio cassette is a little more challenging. read more
