SCIENTISTS CAN SEE AROUND OBSTACLES WITH THIS REALITY HACK THAT TURNS ORDINARY SURFACES INTO MIRRORS

Two scientists from the University of Southern Florida (USF) say they have developed a technique that allows them to see around obstacles.

According to the technique’s inventors, their algorithm, which was inspired by a car crash, can use a single photograph to compute “highly accurate, full-color three-dimensional reconstructions of areas behind obstacles.”

Although still in the development stages, the inventors say they could see several uses for their technique. Potential applications range from traffic safety and military operations to police forces navigating hostage situations.

“We live in a 3D world,” said the technique’s co-inventor, USF assistant professor of computer science John Murray-Bruce, “so obtaining a more complete 3D picture of a scenario can be critical in several situations and applications.”

THE ABILITY TO SEE AROUND OBSTACLES IS ALL IN THE SHADOWS

To create the algorithm, Murray-Bruce and his doctoral student, Robinson Czajkowski, focused on the information available in a digital photograph. Most importantly, they analyzed the data available from shadows cast by objects and structures that are obstructed from the camera’s point of view.

“These shadows are all around us,” Czajkowski said. “The fact we can’t see them with our naked eye doesn’t mean they’re not there.”

In fact, the pair of scientists say there is a ton of information in these shadows that the human eye simply cannot interpret. Their algorithm also incorporates data from “reflections” cast by objects obscured from the camera’s point of view.

NAVAL RESEARCH LABORATORY LEVERAGES EXOTIC PROPERTIES OF 2D WAVEGUIDES TO CAPTURE THE LIGHT OF DARK EXCITONS

A milestone discovery of waveguides based on two-dimensional materials with “exotic” properties has been achieved, according to researchers with the United States Naval Research Laboratory (NRL).

The breakthrough was achieved during studies involving hexagonal boron nitride, a two-dimensional material, by the U.S. Navy’s official corporate research lab while working with researchers from Kansas State University.

EXPERIMENTS IN THE REALM OF 2D MATERIALS

2D materials are a unique class of substances that result from the reduction of a material to its recognized monolayer limits through processes of mechanical peeling. This results in a unique class of ultra-thin 2D materials which have a variety of applications.

The most famous 2D material is graphene, which is formed from bonded carbon atoms to create a sheet that is just one atom in thickness. Such materials can be separated into layers by exploiting what is known as the van der Waals attraction, which describes an attracting force between atoms or molecules that is dependent on distance, rather than chemical bonding.

Following successful recent experiments with graphene, researchers have engaged in experimentation with other novel 2D materials, including hexagonal boron nitride (BN), the softest and most stable of BN’s forms which has already seen applications as a lubricant in machine components, as well as in some cosmetic products.

However, of greater interest to studies at the NRL are the ways these materials can be leveraged at the nanoscale level. This makes them particularly useful for developing applications where extremely thin optical and electrical components are necessary.

Hexagonal boron nitride is a particularly special case, given that past samples examined by NRL scientists revealed its potentially useful optical qualities. However, further studies soon revealed a surprise: that the compound possessed other hidden, and extremely promising capabilities.

DARPA’S NEW REMA PROGRAM IS TURNING ORDINARY DRONES INTO AUTONOMOUS KILLING MACHINES. KIND OF.

The Defense Advanced Research Projects Agency has selected the contractors for their Rapid Experimental Missionized Autonomy (REMA) program, which will practically turn ordinary commercial and military drones into autonomous killing machines.

By joining a program that was announced less than three months ago, the newly awarded partner companies will create a universal system that can equip existing drones with the capability to act autonomously and finish their mission even when the connection to their human operator has been lost.

“REMA is focused on creating autonomous solutions to maximize effectiveness of stock commercial and small military drones on the battlefield,” said Dr. Lael Rudd, REMA program manager when announcing the new awards. “Through creating an autonomy adapter that works with all commercial drones, regardless of manufacturer, and by developing mission-specific autonomy that is constantly refreshed and easy to upload prior to a mission, we aim to give drone operators the advantage in fast-paced combat operations.”

Sarah Silverman’s Lawsuit Against OpenAI Is Full of Nonsense Claims

Is it a crime to learn something by reading a copyrighted book? What if you later summarize that book to a friend or write a description of it online? Of course, these things are perfectly legal when a person does them. But does that change when it’s an artificial intelligence system doing the reading, learning, and summarizing?

Sarah Silverman, comedian and author of the book The Bedwetter, seems to think it does. She and several other authors are suing OpenAI, the tech company behind the popular AI chatbot ChatGPT, through which users submit text prompts and receive back AI-generated answers.

Last week, a federal judge largely rejected their claims.

The ruling is certainly good news for OpenAI and for ChatGPT users. It’s also good news for the future of AI technology more broadly. AI tools could be completely hamstrung by the expansive vision of copyright law that Silverman and the other authors in this case envision.

FLASHBACK: Sentient world: war games on the grandest scale

Perhaps your real life is so rich you don’t have time for another.

Even so, the US Department of Defense (DOD) may already be creating a copy of you in an alternate reality to see how long you can go without food or water, or how you will respond to televised propaganda.

The DOD is developing a parallel to Planet Earth, with billions of individual “nodes” to reflect every man, woman, and child this side of the dividing line between reality and AR.

Called the Sentient World Simulation (SWS), it will be a “synthetic mirror of the real world with automated continuous calibration with respect to current real-world information”, according to a concept paper for the project.

“SWS provides an environment for testing Psychological Operations (PSYOP),” the paper reads, so that military leaders can “develop and test multiple courses of action to anticipate and shape behaviors of adversaries, neutrals, and partners”.

SWS also replicates financial institutions, utilities, media outlets, and street corner shops. By applying theories of economics and human psychology, its developers believe they can predict how individuals and mobs will respond to various stressors.

REVOLUTIONARY AI TOOL, “DEEP-DRAM,” OPENS DOOR TO DISCOVERING UNPRECEDENTED METAMATERIALS WITH “UNUSUAL PROPERTIES”

Researchers from Delft University of Technology in the Netherlands have developed a new artificial intelligence (AI) tool known as “Deep-DRAM” to discover and fabricate novel metamaterials with unparalleled ease and accessibility.

The groundbreaking method promises to revolutionize metamaterial development by streamlining the discovery and creation of durable, custom-designed materials with “unprecedented functionalities” and “unusual properties.”  

“Traditionally, designers use the materials available to them to design a new device or a machine. The problem with that is that the range of available material properties is limited. Some properties that we would like to have just don’t exist in nature,” study co-author and professor of biomechanical engineering, Dr. Amir Zadpoor, explained in a press release by Delft University. 

“Our approach is: tell us what you want to have as properties and we engineer an appropriate material with those properties. What you will then get is not really a material but something in-between a structure and a material, a metamaterial.”

Metamaterials are materials engineered to have properties not found in naturally occurring substances. These engineered composites can defy conventional material properties by deriving their unique characteristics from a structure’s geometry rather than molecular composition. 

Metamaterials are currently employed in various industries, serving practical purposes such as improving antenna performance in telecommunications and controlling sound waves for noise reduction or focusing in acoustic engineering. Recent advancements include creating the world’s first genuine “one-way glass,” showcasing metamaterials, versatility, and potential for innovative applications.

In 2006, two research papers published in Science demonstrated that metamaterials could be used to manipulate the propagation and transmission of specified light frequencies and electromagnetic radiation to render an object invisible. 

Recent publications from Sandia National Laboratories, the U.S. Naval Institute, and Northrop Grumman have discussed the military potential of metamaterials, suggesting the possibility of creating real-life versions of the fictional “Klingon Cloaking Device” or “Harry Potter Invisibility Cloak.” However, despite ongoing research efforts, practical metamaterial cloaking technology has yet to be publicly demonstrated thus far.

This most significant challenge in developing novel metamaterials stems from solving the so-called “inverse problem” or calculating the specific geometry needed to produce desired properties.

Government Funds AI Tools For Whole-Of-Internet Surveillance And Censorship

Ifeel scared. Very scared.

Internet-wide surveillance and censorship, enabled by the unimaginably vast computational power of artificial intelligence (AI), is here.

This is not a futuristic dystopia. It’s happening now.

Government agencies are working with universities and nonprofits to use AI tools to surveil and censor content on the Internet.

This is not political or partisan. This is not about any particular opinion or idea.

What’s happening is that a tool powerful enough to surveil everything that’s said and done on the Internet (or large portions of it) is becoming available to the government to monitor all of us, all the time. And, based on that monitoring, the government – and any organization or company the government partners with – can then use the same tool to suppress, silence, and shut down whatever speech it doesn’t like.

But that’s not all. Using the same tool, the government and its public-private, “non-governmental” partners (think, for example: the World Health Organization, or Monsanto) can also shut down any activity that is linked to the Internet. Banking, buying, selling, teaching, learning, entertaining, connecting to each other – if the government-controlled AI does not like what you (or your kids!) say in a tweet or an email, it can shut down all of that for you.

Yes, we’ve seen this on a very local and politicized scale with, for example, the Canadian truckers.

But if we thought this type of activity could not, or would not, happen on a national (or even scarier – global) scale, we need to wake up right now and realize it’s happening, and it might not be stoppable.

DNA and Developmental Damage from Cell Towers on the Greek Island of Samos: Effects on Insects, Flowers and Vegetables

A recent paper, ‘Human‑made electromagnetic fields: Ion forced‑oscillation and voltage‑gated ion channel dysfunction, oxidative stress and DNA damage (Review) published in the International Journal of Oncology by biophysicist Dimitris J. Panagopoulos et. al. states unequivocally that electromagnetic radiation from wireless technology damages DNA. This leads to infertility, sterility, mutations and extinctions, and it explains the loss of biodiversity that we are currently experiencing on this planet.

DNA damage from wireless radiation is not a new discovery. It has been confirmed over and over by numerous scientists using a variety of experimental subjects and frequencies. But do observations in the laboratory translate into the same effects in the real world? If these scientists are correct, they must do. In the real-world things might be a lot worse, because in the real world we are not exposed to a single frequency or bandwidth but to a whole soup of them, from multiple sources. In the real world, exposure time is not limited to a few minutes or hours per day or week; the cell towers are on day and night. DNA damage from wireless radiation is not a laboratory phenomenon; it is real. We are losing the insects—among them, the pollinators. We are losing the birds. Animals are dying out. We are wiping ourselves out.

The damage to DNA, says Panagopoulos, is being done by the Extremely Low Frequency (ELF) components of the wavebands used in wireless communications. For decades, regulatory bodies such as ICNIRP, SCENIHR (EU), the FCC (USA) and others have insisted that the only way wireless technology can cause damage is by heating tissue, and that the power levels which are allowed protect us from being harmed. This is not true for human beings, and these regulatory bodies have never even considered nature.

Is DNA damage from wireless radiation visible? There have probably been DNA-damaged plants, insects, birds, animals, and people since the first generation of cell towers was erected, but would we recognize what we are seeing? A 2003 study 2 performed by a pair of scientists from the University of Thessaloniki, Greece, studied the effects of exposure to electromagnetic fields on mice exposed at various sites around an antenna park. The newborn mice weighed more than normal newborn mice, and they all had extra vertebrae in the posterior sections of their spines, making them longer than normal mice. This is DNA damage. The mother mice, the dams, produced fewer—and bigger—babies with each litter, and after six months they became irreversibly sterile. This is also DNA damage.

A mouse runs by in a field; would you know that its spine is ever so slightly longer than it should be? I wouldn’t. Would you recognize that a great tit’s eggs are ever so slightly bigger than they ought to be? I wouldn’t. A study of great tits 3 found that birds which made nests near power lines laid bigger eggs with a higher volume of yolk and albumen. That too is DNA damage, and this damaged DNA will be passed on. unless the bird becomes sterile as did the mice in the antenna park study described above.

‘Extremely Alarming’ Election Threats Trigger Warning From FBI

An FBI official warned that state election systems are being targeted as the 2024 election approaches, describing them as “extremely alarming.”

“The threat environment, unfortunately, is very high,” said Tim Langan, executive assistant director for the Criminal, Cyber, Response, and Services Branch of the FBI during a Washington conference with secretaries of state, according to Stateline. “It is extremely alarming.”

Officials said that voter databases could be hacked via phishing or ransomware attacks. They also warned about the rising use of artificial intelligence (AI) that could be used to potentially trick voters, according to the report.

Eric Goldstein, the executive assistant director for cybersecurity at the Cybersecurity and Infrastructure Security Agency (CISA), told the news outlet that there have been significant advancements that could allow China, North Korea, and Russia to target election systems.

“We are in a really difficult cybersecurity environment right now,” he said. “Every single location is at risk regardless of size, regardless of sector,” he added

Neither official provided any concrete examples in the report. But during the event, Kentucky Republican Secretary of State Michael Adams said last month that a bomb threat was called into the state capitol in Frankfort, saying that explosives would “make sure you all end up dead.” No bombs were found, and eight other state capitols received threats.

A BREAKTHROUGH IN THE CONTROL OF QUANTUM PHENOMENA AT ROOM TEMPERATURE HAS BEEN ACHIEVED, RESEARCHERS SAY

Quantum physics and mechanical engineering have been united in a breakthrough method allowing the control of quantum phenomena at room temperature, according to the findings of a pioneering new study.

In quantum mechanics, observing and controlling quantum phenomena has traditionally only occurred under conditions where temperatures approach absolute zero. Theoretically the coldest temperature attainable and roughly equivalent to around -459.67 Fahrenheit, absolute zero is the point at which matter becomes so cold that the motion of particles would cease.

Although allowing for easier detection of quantum effects, reaching such astoundingly cold temperatures is not easy, and has limited applications and studies involving quantum technologies.

“Reaching the regime of room temperature quantum optomechanics has been an open challenge since decades,” says Tobias J. Kippenberg, the co-author of a new study that, based on its findings, could finally present practical ways of overcoming such challenges.

According to Kippenberg, the new work has brought what physicists call Heisenberg’s microscope—once only realized as a theoretical model—into reality.
