The attack threatens users with location-tracking, DoS, fake notifications and more.

Privacy-breaking flaws in the 4G and 5G mobile protocols could allow attackers to intercept calls, send fake amber alerts or other notifications, track location and more, according to a research team from Purdue University and the University of Iowa.

In a paper presented at Mobile World Congress in Barcelona this week, the researchers explained that the issues arise from weaknesses in the cellular paging (broadcast) protocol. They started with the fact that when a mobile device is in its idle, low-power state, it will conserve battery life partly by polling for pending services only periodically.

Mice with vision enhanced by nanotechnology were able to see infrared light as well as visible light, reports a study published February 28 in the journal Cell. A single injection of nanoparticles in the mice’s eyes bestowed infrared vision for up to 10 weeks with minimal side effects, allowing them to see infrared light even during the day and with enough specificity to distinguish between different shapes. These findings could lead to advancements in human infrared vision technologies, including potential applications in civilian encryption, security, and military operations.

Injectable photoreceptor-binding nanoparticles with the ability to convert photons from low-energy to high-energy forms allow mice to develop infrared vision without compromising their normal vision and associated behavioral responses.

Phinergy is a leading developer of breakthrough, absolutely zero emission, high energy density systems based on metal air energy technologies, mainly Aluminum-Air and Zinc-Air. Unlike conventional batteries that carry oxygen, these batteries freely breathe oxygen from the ambient air to release the energy contained in metals.

Energy storage could prove an inexpensive way for power companies to handle heat waves and other times when consumers use more electricity than usual.

Shaking a physical system typically heats it up, in the sense that the system continuously absorbs energy. When considering a circular shaking pattern, the amount of energy that is absorbed can potentially depend on the orientation of the circular drive (clockwise/anti-clockwise), a general phenomenon known as circular dichroism.

In 2017, Nathan Goldman (ULB, Brussels), Peter Zoller (IQOQI, Innsbruck) and coworkers predicted that circular dichroism can be quantized in quantum systems (heating is then constrained by strict integers) forming a “topological state.” According to this theoretical prediction, the quantization of energy absorption upon circular driving can be directly related to topology, a fundamental mathematical concept that characterizes these intriguing states of matter.

Writing in Nature Physics, the experimental group of Klaus Sengstock and Christof Weitenberg (Hamburg), in collaboration with the team of Nathan Goldman, reports on the first observation of quantized circular dichroism. Following the theoretical proposal of Goldman, Zoller et al., the experimentalists realized a topological state using an ultracold atomic gas subjected to laser light, and studied its heating properties upon circular shaking of the gas. By finely monitoring the heating rates of their system, for a wide range of driving frequencies, they were able to validate the quantization law predicted by Goldman, Zoller et al. in 2017, in agreement with the underlying topological state realized in the laboratory.

Wow, anybody remember the Grain Belt Express? No? No wonder! The massive 700-mile wind power transmission project in the US Midwest has been on the boards since at least 2011. It got off to a promising start but suffered death by a thousand cuts when state officials in Missouri balked.

Well, it looks like the naysayers forgot to cut off its head or at least sever the spinal cord, because the Grain Belt Express could come back to walk the Earth once more.

GE Global Research has just developed a carbon dioxide powered turbine that could produce super efficient energy — and it is remarkably small.

Talga Resources has revealed new test results on the ongoing optimization of its graphene silicon Li-ion battery anode product, Talnode™- Si. According to Talga, the battery anode product returns further performance gains, now delivering ~70% more energy density than commercial graphite-only anodes.

The product reportedly provides a “drop in” solution for improving current Li-ion battery performance. Commercial samples under confidentiality and material transfer agreements are scheduled to commence delivery around the end of February 2019 — recipients are said to include some of the world’s largest electronic corporations.

For your convenience, a search was performed using the query ‘talga reports positive test results its graphene silicon li ion battery anode project talnode si’:

The Chinese military is looking to procure test systems for magnetized plasma artillery, according to a notice on the People’s Liberation Army (PLA) weapon and equipment procurement website weain.mil.cn last week.

Released on Wednesday and due expire on Thursday, the notice invites tenders for a theory-testing and a launch system for magnetized plasma artillery.

Although the weapon sounds as if it comes from a sci-fi movie, it will probably not shoot high-energy plasma but ultra-high velocity cannon shells.
