Free-space optical communication, the communication between two devices at a distance using light to carry information, is a highly promising system for achieving high-speed communication. This system of communication is known to be immune to electromagnetic interference (EMI), a disturbance generated by external sources that affects electrical circuits and can disrupt radio signals.
While some studies have highlighted the possible advantages of free-space optical communication, this system of communication has so far come with certain limitations. Most notably, it is known to offer limited security against eavesdroppers. Researchers at Télécom Paris (member of Institut Polytechnique de Paris), mirSense, Technische Universität Darmstadt and University of California Los Angeles (UCLA) have recently introduced a unique system for more secure free-space optical communication based on a technology known as quantum cascade laser, a specific type of semiconductor laser that typically emits mid–infrared light.
“The core idea behind our research is that private free-space communication with quantum key distribution (i.e., based on quantum physics properties) is promising, but it is probably years away, or even further,” Olivier Spitz, one of the researchers who carried out the study, told TechXplore. “Currently, the main limitations of this technology are the requirements for cryogenic systems, very slow data rates and costly equipment.”
Over the past few decades, roboticists and computer scientists have developed artificial systems that replicate biological functions and human abilities in increasingly realistic ways. This includes artificial intelligence systems, as well as sensors that can capture various types of sensory data.
When trying to understand properties of objects and how to grasp them or handle them, humans often rely on their sense of touch. Artificial sensing systems that replicate human touch can thus be of great value, as they could enable the development of better performing and more responsive robots or prosthetic limbs.
Researchers at Sungkyunkwan University and Hanyang University in South Korea have recently created an artificial tactile sensing system that mimics the way in which humans recognize objects in their surroundings via their sense of touch. This system, presented in a paper published in Nature Electronics, uses sensors to capture data associated with the tactile properties of objects.
Microsoft, via its Security Intelligence account on Twitter, has issued a warning to Windows users of a new type of phishing scam that involves emails requesting users to dial a call center. They warn users to not dial the call center because following the instructions given by a human operator can lead to malware infections. The malware scam only works with Windows computers that have Microsoft Excel.
The new threat involves BazarLoader, a type of malware that allows backdoor access to infected computers. BazarLoader works by allowing criminals to sneak in through a hidden backdoor on a user’s computer, which allows them to install viruses or other types of malware. Over the past several years, criminals have used different methods to trick users into carrying out instructions that allow BazarLoader to infect their computer. In this new campaign, Microsoft reports that such criminals are using an email/call center approach.

Without GPS, autonomous systems get lost easily. Now a new algorithm developed at Caltech allows autonomous systems to recognize where they are simply by looking at the terrain around them—and for the first time, the technology works regardless of seasonal changes to that terrain.
Details about the process were published on June 23 in the journal Science Robotics.
The general process, known as visual terrain-relative navigation (VTRN), was first developed in the 1960s. By comparing nearby terrain to high-resolution satellite images, autonomous systems can locate themselves.

In September 1983, the CIA’s Directorate of Intelligence produced a report: “Soviet Satellite Defense Against the US Miniature Vehicle Antisatellite Weapon.” The report stated that “Our estimates of Soviet technological advances and of Soviet perceptions of the ASAT threat indicate a moderate likelihood that the Soviets will develop additional defensives—decoys, electronic countermeasures, and signature reduction—by the late 1990s.”
“If we were to find [aliens] with whom we could carry on a conversation, I think they would be remarkably like us.”
When talking about aliens, zoologist Arik Kershenbaum believes we need to adopt a new language.
“We need a language to speak about aliens, which is not the language of Hollywood,” he tells Inverse. In fact, maybe we should scrap the term “alien” altogether.
