Robo-Dog Assault Droids 😲
CHILLING video shows the Chinese military unveiling more of their high-tech weapons as tensions continue to rage with the West.
Beijing flaunted its military tech in the new video which shows a machine-gun armed robot dog, a small ball scout drone and a soldier wearing an exoskeleton.
It is understood the technology is made by Chinese defence firm Kestrel and the clips from the exercises were shared on Beijing’s state-monitored social media site Weibo.
Two-dimensional (2D) semiconductors, like transition-metal dichalcogenides, have become a competitive alternative to traditional semiconducting materials in the post-Moore era, and caused worldwide interest. However, before they can be used in practical applications, some key obstacles must be resolved. One of them is the large electrical contact resistances at the metal-semiconductor interfaces. Researchers have proposed a brand-new contact resistance lowering strategy of 2D semiconductors with a good feasibility, a wide generality and a high stability.
Hydrogen (H 2) is currently discussed as an ideal energy carrier in a world requiring renewable energies. Hydrogen has the highest gravimetric energy density of all chemical fuels (141 MJ/kg), which is three times higher than gasoline (46 MJ/kg). However, its low volumetric density restricts its widespread use in transportation applications —as current storage options require a lot of space.
At ambient temperature, hydrogen is a gas, and one kilogram of hydrogen occupies a volume of 12,000 liters (12 cubic meters). In fuel-cell vehicles, hydrogen is stored under a very high pressure of 700 times the atmospheric pressure, which reduces the volume to 25 liters per kilogram of H 2.
Liquid hydrogen shows a higher density resulting in 14 liters per kilogram, but it requires extremely low temperatures since the boiling point of hydrogen is minus 253 °C.
Two-dimensional van der Waals materials have been the focus of work by numerous research groups for some time. Standing just a few atomic layers thick, these structures are produced in the laboratory by combining atom-thick layers of different materials (in a process referred to as “atomic Lego”).
Interactions between the stacked layers allow the heterostructures to exhibit properties that the individual constituents lack.

A Turkish entity going by the name of Nitrokod has been accused of running a campaign by spoofing a desktop version of Google Translate to actively mine cryptocurrency from its more than 111,000 users across eleven countries (UK, US, Sri Lanka, Greece, etc., Israel, Germany, Turkey, Cyprus, Australia, Mongolia, and Poland) in 2019.
In addition to Google Translate, there are five other fake desktop applications on the Nitrokod website. Most of them impersonate programs that are not officially available as desktop applications, but as web or mobile applications, which makes the desktop version created by the attackers particularly attractive. In any case, they are popular applications that can be found on websites such as Softpedia and UpToDown.
Six fake applications available on the Nitrokod website. When installing any of these programs, the malicious effects do not manifest until after a sequence of dropper for almost a month after installation, in order to hide such effects from the antiviruses.
Scientists have long pondered how and when the evolution of prokaryotes to eukaryotes occurred. A collaborative research team from Tohoku University and the University of Tokyo may have provided some answers after discovering new types of microfossils dating 1.9 billion years.
Details of their findings were published in the journal Precambrian Research on August 19, 2022.
The Gunflint Formation traverses the northern part of Minnesota into Ontario, along the northwestern shores of Lake Superior. The first bacterial microfossils were discovered there in 1954, with Gunflint microfossils now recognized as a “benchmark” in the field of life evolution.
Physicists from Japan and the U.S. used atoms about 3 billion times colder than interstellar space to open a portal to an unexplored realm of quantum magnetism.
“Unless an alien civilization is doing experiments like these right now, anytime this experiment is running at Kyoto University it is making the coldest fermions in the universe,” said Rice University’s Kaden Hazzard, corresponding theory author of a study published on September 1, 2022, in the journal Nature Physics.
As the name implies, Nature Physics is a peer-reviewed, scientific journal covering physics and is published by Nature Research. It was first published in October 2005 and its monthly coverage includes articles, letters, reviews, research highlights, news and views, commentaries, book reviews, and correspondence.
SpaceX’s partnership with NASA just got $1.4 billion sweeter, as the space agency announced Wednesday that it’s extending its deal with the company to cover five additional missions.
Amazon is having to curtail growth of its vast delivery network which exploded in size during the pandemic.
Practical nuclear fusion is, famously, always 10 years in the future. Except that the Pentagon recently gave an award to a tiny startup to launch a fusion power system into space in just five.
There is no shortage of organizations, from VC-backedstartups to nation states, trying to realize the dream of cheap, clean, and reliable power from nuclear fusion. But Avalanche Energy Designs, based near a Boeing facility in Seattle, is even more ambitious. It is working on modular “micro fusion packs,” small enough to hold in your hand yet capable of powering everything from electric cars to spaceships.
Last month, the Pentagon’s Defense Innovation Unit (DIU) announced it had awarded Avalanche an unspecified sum to develop its Orbitron fusion device to generate either heat or electricity, with the aim of powering a high-efficiency propulsion system aboard a prototype satellite in 2027. The contract to Avalanche was one of two awarded by the DIU—the second going to Seattle-based Ultra Safe Nuclear for development of its radioisotope battery.
