The cure for cancer might have been inside us all along – our own immune system. The trick is to give it a boost to find and destroy those rogue cells, and that’s the focus of the field of immunotherapy. To that end, a new hydrogel has been developed that can be injected directly to the site of a tumor, where it stays to slowly release its payload of immunotherapy drugs for longer.
The U.S. Army has chosen a new rifle designed to allow infantry squads to hit targets at greater ranges. The Heckler and Koch G28 designated marksman rifle will give infantrymen a weapon guaranteed to penetrate enemy body armor at longer ranges than existing M4 carbines. The move is an acknowledgement that the Army could someday fight enemies equipped with advanced body armor, which is part of the Army’s reorientation to the world of conflicts between large powers.
Pioneering theoretical physicist and science popularizer Stephen Hawking has passed away at the age of 76. Details have not been released yet, but the BBC reports that his children Lucy, Robert and Tim have released a statement saying, “We are deeply saddened that our beloved father passed away today. He was a great scientist and an extraordinary man whose work and legacy will live on for many years.”
Samsung has whipped the covers off its lineup of 2018 TVs, just a day after LG did the same. Along with some OLED devices, the flagships of the range are built with Quantum dot light-emitting diode (QLED) display technology, and the entire line varies in size from a modest 40 in up to a monstrous 88 in. Since they can take up so much living room real estate, Samsung has also packed in a few new features to let the TVs earn their keep even while not in use.
Tesla made quite a statement when it finally unveiled its all-electric long hauler last year, listing some truly impressive numbers in terms of range and acceleration. The might of the Tesla Semi’s is now being put to the test, with a production model rolling out of the Gigafactory with a load onboard for the very first time.
China boasts more than its fair share of impressive engineering feats, including the world’s second-tallest skyscraper and the highest bridge. We can soon add highest skybridge to the list too, courtesy of Moshe Safdie’s Raffles City Chongqing project, which is currently under construction in southwest China.
Harvard has reported a breakthrough flat artificial eye just 30 microns in depth which can exceed the capabilities of the human eye. The technology, which builds on so-called metalens technology by adding electrically-controlled flexible muscles, could make a real impact in all manner of optical fields, including those in cameras, telescopes, microscopes, glasses and even virtual reality.
We’re so used to having our everyday devices powered by lithium-ion batteries that sometimes it’s hard to imagine using anything else. But there are plenty of teams working on alternatives like lithium-air, sodium-ion, lithium-metal and aluminum-ion designs that may help solve some of the drawbacks of lithium-ion batteries. The latest, an aqueous hybrid capacitor, is stable, safe and boasts high energy and power densities, recharging in as little as 20 seconds.
