Ancient beer discovery hints China had ‘advanced brewing’ 5,000 years ago

Ancient beer discovery hints China had ‘advanced brewing’ 5,000 years ago

China was home to ‘advanced beer-brewing’ techniques 5,000 years ago, a new study suggests, and it may have been the reason barley was imported and established in the region. Researchers have reached their conclusion based on the analysis of pottery vessel remnants with ancient beer residue inside; this ancient beer recipe includes millet, Job’s tears, tubers, and barley in the ingredients.

DARPA awards contract for underwater positioning system

DARPA awards contract for underwater positioning system

The U.S. Navy has autonomous watercraft aspirations, and it needs a way for future unmanned (and manned) subs to navigate accurately. Here to help is DARPA, which has selected BAE Systems to create an underwater positioning system for deep ocean navigation (POSYDON). The program will produce a navigation system that eliminates the need to surface for updated GPS data.

This breathalyzer wearable detects alcohol levels through the skin

This breathalyzer wearable detects alcohol levels through the skin

Wearables can track can track all kinds of health a fitness data these days, but here's one that focuses on something different: how much alcohol you drink. Called BACTrack Skyn, the wristband acts like a wearable breathalyzer, even though you don't technically breathe into it. Instead, it measures blood alcohol levels through you skin using fuel cell technology similar to what law enforcement relies on.

Superjet desert tests pave way for ultra-fast commercial flights

Superjet desert tests pave way for ultra-fast commercial flights

The future of long-distance travel is looking more exciting than ever -- forget Amtrak, we'll have a Hyperloop. And what about flights? Work has been underway to create a so-called 'superjet' able to travel at ridiculously fast speeds, and that technology was recently successfully tested in the Australian desert. The effort, a collaboration between U.S. and Australian military research teams, involves hypersonic technology able to take planes from Sydney to London in a mere two hours.

April was the 12th consecutive ‘hottest’ recorded month

April was the 12th consecutive ‘hottest’ recorded month

Every month brings the same news -- that month was the new 'hottest' month on record, edging past the previous month to paint a dire picture for the planet's climate. Soon enough, the record-breaking had formed a trend, and now NOAA has confirmed the news: we’ve officially had a year-long streak of record-breaking warm weather. The temps were detailed in NOAA’s latest State of the Climate report.

IBM’s 3-bit phase-change memory could combine RAM, flash

IBM’s 3-bit phase-change memory could combine RAM, flash

In an ideal world, computers would only have one type of data storage, but thanks to the laws of physics and businesses, we have two main types (three if you count CPU L caches). There's DRAM or RAM, which is fast, expensive, and doesn't retain its data without power. And then there's regular storage, today represented by NAND flash, which has more capacity, retains its data longer, but is slower in comparison. Combining all those benefits, without the drawbacks, has been one of the holy grails of computing. And IBM might have found its version of the answer in its 3-bit phase-change memory.

Smarter and sleeker: This is Acura’s new self-driving prototype

Smarter and sleeker: This is Acura’s new self-driving prototype

Acura has revealed its second-generation autonomous car prototype, smarter and more capable of potentially tricky road conditions than its predecessor. The new car has been outfitted with an updated batch of sensors, but arguably more important is the fresh software, with a new set of algorithms that Acura claims will be more resilient to changing real-world challenges.

Prosthetic bionic arm has integrated charger, light, and drone

Prosthetic bionic arm has integrated charger, light, and drone

About four years ago, a man called James had a freak accident while trying to board a train that resulted in him falling under the train, severing his left leg, and severely damaging his left arm among other grievous injuries. The left arm was eventually amputated. The man recovered and was given an incredible prosthetic arm that has all sort of integrated functions in an experiment that seems right out of a science fiction movie.

Spiders’ sticky ‘glue’ also acts as microscopic web spools

Spiders’ sticky ‘glue’ also acts as microscopic web spools

Spiders create a special sort of ‘hybrid’ substance for their web that keeps the silky threads taunt even after they’re stretched out, according to researchers, and that discovery has been used to create a so-called liquid wire with the same properties. The spider’s substance is described as a watery glue deposited in tiny drops onto the threads; when a piece of silk is pulled on or stretched out, it spools within the droplets, keeping the threads taunt and thusly maintaining the structure of the web.

Soft and stretchable power pack has tiny lithium-ion batteries

Soft and stretchable power pack has tiny lithium-ion batteries

Normally when we talk about power packs or batteries for electronic devices we are looking at large rigid structures that take up lots of space inside the device. That sort of battery works just fine for gadgets like phones or laptop computers, but when you are talking about thin wearable sensors and other electronics meant to be actually on the skin powering the devices is a challenge.

Israeli divers find ancient Roman treasure in shipwreck remains

Israeli divers find ancient Roman treasure in shipwreck remains

A team of Israeli divers have discovered a cache of ancient Roman treasure within the remains of a shipwreck, the nation has announced. A pair of divers made the discovery back in April, finding the remains of a shipwreck in an ancient Roman port, and further investigation by the Israel Antiquities Authority revealed a cache of ancient treasures…most of which is in surprisingly good shape considering how long it spent underwater.

Study: many Americans limit Internet use over a roster of fears

Study: many Americans limit Internet use over a roster of fears

The U.S. Department of Commerce’s National Telecommunications & Information Administration (NTIA) has published a new study that found a combination of concerns about security and privacy are causing some Americans to limit their online activities, something that could, over time, impact the economy and more. The lack of trust in online safety comes at a time when report after report details mass government spying against citizens and cybersecurity breaches that leave ordinary users exposed and vulnerable.
