Kathy Patten, a grandmother from Baltimore, suffered a heart attack and spent 45 long minutes clinically dead. But some intense CPR actually managed to bring her back to life, giving her a second chance that local news stations are calling a “medical miracle.”
Patten has reportedly made an almost full recovery, something that is exceedingly rare. While TV dramas give the impression that CPR is often successful, the reality is grim. Only around 10.6 percent of those who experience cardiac arrest are later discharged from the hospital, according to a 2018 study, though those numbers fluctuate depending the severity and timing of the incident.
“I’m so grateful God gave me a second chance,” Patten told CBS affiliate WJZ-TV. “I’m just going to be the best person I can be. It’s very scary, coming back is a second chance of life.”
Forward-looking: A team of researchers have devised a new method for protecting SSDs from ransomware attacks. It can detect ransomware, stop it in its tracks, and even recover stolen data in a matter of seconds. The cost should only be a minor increase in the SSD’s latency.
The Register spoke with the researchers, who come from Inha University, the Daegu Gyeongbuk Institute of Science & Technology (DGIST), the University of Central Florida (UCF), and the Cyber Security Department at Ewha Womans University (EWU). The system, called SSD-Insider, is supposedly almost 100 percent accurate and has been tested on real-world ransomware.
SSD-Insider works by recognizing certain patters in SSD activity that are known to indicate ransomware. “To recognize ransomware activity by viewing only the distribution of IO request headers, we have paid attention to a ransomware’s very unique behavior, overwriting,” reads the team’s research paper proposing SSD-Insider. It specifically points out the behavior of ransomware like WannaCry, Mole, and CryptoShield.
An Australian company has launched an erasable computer memory chip that retains data when its power source is switched off. The chip could revolutionise the design of computers and other electronic devices by doing away with the bulky magnetic disc memories that are currently used to store data permanently.
Current computers rely on a selection of memory devices. These include chips known as read-only memories or ROMs that store preprogrammed data without power but cannot be erased, and instantly erasable chips that require constant power, known as random-access memory or RAMs. To store more data and programs when the power is off, most computers use magnetics discs.
The new chip is known as a ferroelectric random-access memory or FRAM. If it proves as successful as its developer, Ramtron, claims, it could replace all other types of data storage.
The ultimate goal of neuroscience is to learn how the human brain gives rise to human intelligence and what it means to be intelligent. Understanding how the brain works is considered one of humanity’s greatest challenges.
Jeff Hawkins thinks that the reality we perceive is a kind of simulation, a hallucination, a confabulation. He thinks that our brains are a model reality based on thousands of information streams originating from the sensors in our body. Critically — Hawkins doesn’t think there is just one model but rather; thousands.
Jeff has just released his new book, A thousand brains: a new theory of intelligence. It’s an inspiring and well-written book and I hope after watching this show; you will be inspired to read it too.
A spectacular portrait of the galaxy Centaurus A has been captured by astronomers using the Dark Energy Camera mounted on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile. This galaxy’s peculiar appearance—cloaked in dark tendrils of dust—stems from a past interaction with another galaxy, and its size and proximity to Earth make it one of the best-studied giant galaxies in the night sky.
The galaxy Centaurus A, which lies over 12 million light-years away in the direction of the southern-hemisphere constellation Centaurus (The Centaur), is the leading light of this striking image. This image provides a spectacular view of the luminous glow of stars and the dark tendrils of dust that hide the bright center of the galaxy. This dust is the result of a past galactic collision, in which a giant elliptical galaxy merged with a smaller spiral galaxy. As well as large amounts of gas and dust, Centaurus A’s dust lane contains widespread star formation, as indicated by the red clouds of hydrogen and by the large number of faint blue stars visible at each end of the dust lane.
The proximity and brightness of Centaurus A—it is one of the closest giant galaxies to Earth—make it one of the best-studied objects in the southern hemisphere night sky. Since its discovery in 1,826 scientists have studied the galaxy exhaustively with many different kinds of telescopes, revealing a variety of intriguing features. Radio telescopes reveal a colossal jet of matter spewing outward from the heart of the galaxy. This jet is accelerated to almost half the speed of light by a supermassive black hole at the center of Centaurus A, and its bright emissions at radio wavelengths make this galaxy one of the most prominent radio sources in the night sky. In fact, in July 2,021 the Event Horizon Telescope produced an image of a jet launching from the black hole in Centaurus A, which weighs in at 55 million times the mass of the Sun.
Integrated circuits (ICs) based on organic transistors have many valuable applications, for instance, in the fabrication of paper-like displays or other large-area electronic components. Over the past few decades, electronics engineers worldwide have developed a variety of these transistors.
A promising alternative to these transistors are vertical-channel dual-gate organic thin-film transistors. These transistors have several advantageous properties, such as short channel lengths and tuneable threshold voltages (VTH). Despite these advantages, due to a lack appropriate p-and n-type devices, developing complementary inverter circuits for these transistors has so far proved challenging.
Researchers at Technische Universitat Dresden, Helmholtz-Zentrum Dresden Rossendorf (HZDR) and Northwestern Polytechnical University have recently developed vertical organic permeable dual-base transistors that could be integrated in logic circuits. In a recent paper published in Nature Electronics, they evaluated the potential use of these transistors in complex integrated circuits.
The US Army is seeking to develop a high-altitude warfare sensor that can fly over enemy territories, transmit data, and potentially even work as a jammer to disrupt an adversary’s communications system.
The project is called High-Altitude Extended-Range Long Endurance Intelligence Observation System, or HELEIOS.
Army capability manager for electronic warfare, Col. Daniel Holland, provided some key details about the device during a military forum on August 17 Army Timesreported. HELEIOS will see a sensor attached to a solar glide device or an observation balloon, Holland explained.
Aerospace giant Honeywell is teaming up with anti-jamming expert InfiniDome to develop a new drone sensor capable of enhancing GPS resiliency when signals are weak or experiencing blockages. The new tech, which is being designed for defense and commercial users alike, is expected to hit markets during the first semester of next year.
Drones being flown for all sorts of purposes rely on GPS signals for situational referencing and carrying out tasks assigned to particular locations. The importance of maintaining those feeds, therefore, has become critical to even the most ordinary operation. That dependability of GPS connectivity, however, can be compromised by surrounding structure density – like clusters of high rises, or flights below bridges – or complicated by the ever-proliferating number of craft in the skies at any given time.
Optical image stabilization combined with a lot more zoom.
Apple has been beaten to the periscope “folded” camera punch by pretty much every other smartphone manufacturer, but it continues to design and patent new takes on the now-commonplace tech. It was granted a patent for a new design that includes folded optics and “lens shifting” capabilities.
Folded optics, or more commonly known as periscope cameras, are a design that allows smartphones to gain considerably more optical zoom than a typical lens design by placing the lens array parallel to the long edge of a smartphone body and bending the transmission of light to the sensor by using one or more prisms. The design has been used by Samsung, Huawei, and others to make smartphone cameras that sport massive optical zooming capabilities compared to what Apple offers.
This latest patent was filed in January of2019but finally granted and published on August 17 of this year, as noted by Patently Apple.
