A Harvard team is addressing the challenges of grid storage by designing a flow battery based on inexpensive organic molecules in aqueous (water-based) electrolyte. The team has focused on non-toxic quinone molecules, which can be found in plants such as rhubarb, as an electroactive chemical that can reversibly store energy in a water-based solution at …
The US Navy operated 75 nuclear-powered submarines in 2014, with around 15 being the more modern Virginia or Seawolf-class designs, according to the World Nuclear Association. However, it deploys just four Los Angeles-class submarines in the Asia-Pacific region, operating out of its naval base in Guam. In 2017, the US would spend more than US$8 …
The Alternative Defense Strategies in a Cost-Capped Environment study identified five alternative strategies and used CSIS’s Force Cost Calculator to build the cost-capped force structure, modernization, and readiness profile optimized for each strategy. In addition to assessing the strengths and weaknesses of each defense strategy, this study stress-tested each strategy against four sets of simultaneous …
The Yi4K Action Camera is almost exactly a GoPro Hero4 Black. It has similar features. The Hero4 Black costs $500, and the Yi 4K costs $250. The Yi 4K beats the Go Pro Hero4 Black on a spec for spec basis It has twice the battery life and a built in touchscreen Brian WangBrian Wang …
Dell designed a unique approach to liquid cooling that’s built on Dell’s rack-scale infrastructure. Is is a completely new datacenter cooling solution from the ground up to improve performance during peak times while reducing their total cost of ownership (TCO). It was a proof of concept for EBay that is being made broadly available. Because …
Russia sent three 152-mm self-propelled guns into Ukraine. The next version of Russia’s T14 Armata main battle tank will be armed with a previously rumored 152mm gun. The 152 mm tank gun could penetrate 1 meter of armor. For 11 years, China has been testing a 140mm gun on one its Type 98 tanks. The …
For the second time, scientists have directly detected gravitational waves — ripples through the fabric of space-time, created by extreme, cataclysmic events in the distant universe. The team has determined that the incredibly faint ripple that eventually reached Earth was produced by two black holes colliding at half the speed of light, 1.4 billion light …
Researchers at Sandia National Laboratories’ Combustion Research Facility are helping to develop sparkplug-free engines that will help meet ambitious automotive fuel economy targets of 54.5 miles per gallon by 2025. They are working on low-temperature gasoline combustion (LTGC) operating strategies for affordable, high-efficiency engines that will meet stringent air-quality standards. Sandia researchers Isaac Ekoto and …

Brian WangBrian Wang is a Futurist Thought Leader and a popular Science blogger with 1 million readers per month. His blog Nextbigfuture.com is ranked …
Researchers have developed a method for printing optical holographic lenses that could greatly simplify their fabrication. Because the method can be performed quickly and easily, it could potentially be used by astronauts to print lenses while in space for holographic lens telescopes. While current holographic lens fabrication methods are often expensive, time-consuming, and labor-intensive, the …
The DARPA Semiconductor Technology Advanced Research Network (STARNet) program is a government-industry partnership combining the expertise and resources from select defense, semiconductor, and information companies with those of DARPA to sponsor an external set of academic research teams that are focused on specific technology needs set by experts in industry and government. Efforts under this …
