‘Smart’ Male Chastity Device Vulnerable To Locking By Hackers: Researchers

By iwano@_84

A security flaw in an internet-connected male chastity device could allow hackers to remotely lock it — leaving users trapped, researchers have warned.

The Cellmate, produced by Chinese firm Qiui, is a cover that clamps on the base of the male genitals with a hardened steel ring, and does not have a physical key or manual override.

The locking mechanism is controlled with a smartphone app via Bluetooth — marketed as both an anti-cheating and a submission sex play device — but security researchers have found multiple flaws that leave it vulnerable to hacking.

“We discovered that remote attackers could prevent the Bluetooth lock from being opened, permanently locking the user in the device. There is no physical unlock,” British security firm Pen Test Partners said Tuesday.

“An angle grinder or other suitable heavy tool would be required to cut the wearer free.”

The firm also found other security flaws

Researchers use drones to monitor water flows in the ground

For eight years, an area in Luxembourg measuring about 300 square kilometers was under special surveillance. Research groups from all over Europe analyzed the Attert River catchment area, drones flew over it with thermal imaging cameras, and satellites measured the radiation. Meanwhile, research teams were in the fields determining the composition of the soil. The data was then used for elaborate computer modeling calculations. The aim of these efforts was to solve a mystery that has intrigued people since the beginnings of agriculture: How does water flow on the surface of the Earth and in the ground?

This question is not only relevant for agriculture, it is also central to understanding the impact of climate change or predicting

Researchers explore the effect of screen time on vision

By iwano@_84

The coronavirus pandemic has shifted many of our interactions online, with Zoom video calls replacing in-person classes, work meetings, conferences and other events. Will all that screen time damage our vision?

Maybe not. It turns out that our visual perception is highly adaptable, according to research from Psychology Professor and Cognitive and Brain Sciences Coordinator Peter Gerhardstein’s lab at Binghamton University.

Gerhardstein, Daniel Hipp and Sara Olsen — his former doctoral students — will publish “Mind-Craft: Exploring the Effect of Digital Visual Experience on Changes in Orientation Sensitivity in Visual Contour Perception,” in an upcoming issue of the academic journal Perception.

Hipp, the lead author and main originator of the research, is now at the VA Eastern Colorado Health Care System’s Laboratory for Clinical and Translational Research. Olsen, who designed stimuli for the research and aided in the analysis of the

WPI Researchers Expanding Development of Oxygen Sensor for Babies to also Monitor COVID-19 Patients | News

By iwano@_84

An interdisciplinary group of researchers at WPI is expanding their work to develop a small wireless mobile sensor that will measure a baby’s blood oxygen levels to also create a similar sensor that can act as early detection device for COVID-19 infections.

“COVID-19 is all about respiration,” said Ulkuhan Guler, assistant professor of electrical and computer engineering and director of WPI’s Integrated Circuits and Systems Lab, who is leading the project. “The electronics we have been developing for the baby oxygen sensor will be the same for COVID patients, so we’re in a good position to fine tune the design for babies and adults. We’re producing prototypes for both at the same time.”

The pandemic has put an enormous strain on the healthcare system, filling hospitals, depleting medical supplies, and exhausting healthcare providers. It also has put healthcare workers at risk. According to a studyconducted in part by Massachusetts General

Pittsburgh Researchers Design Computer Software That Detects Osteoarthritis Before Symptoms Develop

By iwano@_84

PITTSBURGH (KDKA) — More than 3 million Americans and almost 25 percent of Pennsylvanians have osteoarthritis, a debilitating joint disease.

Currently, there is no cure. Osteoarthritis contributes to the hundreds of thousands of joint replacement surgeries performed in the U.S. each year.

Local researchers are now using artificial intelligence to identify the disease much sooner, along with a possible cure.

“This is allowing us to follow along with what the computer is seeing,” said Dr. Ken Urish, a researcher at UPMC.

Researchers from the University of Pittsburgh and Carnegie Mellon University have designed computer software that detects osteoarthritis years before symptoms develop.

“The biggest lesson I have learned from my job is that people completely take for granted the ability to walk a block and not have it hurt,” said Dr. Urish.

The disease is typically diagnosed using a standard grayscale MRI. It’s only visible once the cartilage has

Researchers found the manual for the world’s oldest surviving computer

By iwano@_84

Researchers will be able to gain a deeper understanding of what’s considered the world’s oldest surviving (digital) computer after its long-lost user manual was unearthed. The Z4, which was built in 1945, runs on tape, takes up most of a room and needs several people to operate it. The machine now takes residence at the Deutsches Museum in Munich, but it hasn’t been used in quite some time.

An archivist at ETH Zurich, Evelyn Boesch, discovered the manual among her father’s documents in March, according to retired lecturer Herbert Bruderer (via Motherboard). René Boesch worked with the Swiss Aeronautical Engineering Association, which was based at the university’s Institute for Aircraft Statics and Aircraft Construction. The Z4 was housed there in the early 1950s.

Among Boesch’s documents were notes on math problems the Z4 solved that were linked to the development of the P-16 jet

University of Wyoming researchers once again have advanced artificial intelligence technology to identify images of wild animals from camera-trap photographs in North America.

The researchers used 3 million camera-trap images from 18 studies in 10 U.S. states to develop two computer models that demonstrated remarkable accuracy and efficiency in accomplishing a task that is important in wildlife research.

The project, detailed in an article in the journal Ecology and Evolution, makes the technology more accessible to biologists who do not have advanced computational skills. It builds on previous research that shows the artificial intelligence technique called deep learning can take the place of slow, tedious analysis of individual photos by people.

“Training a model that can be used to

Researchers make futuristic wool that is able to ‘remember’

By iwano@_84

Researchers at Harvard University have created a new material made that can remember its original shape, so no matter how it is stretched it can always return to its original design.

In a video, a wool cylinder is placed in a solution of water and morphs its shape back into its original, programmed flower shape.

Another shows a stretched piece of material dramatically reduce its length in a matter of seconds.

The material is made using keratin, the protein found in hair and nails. In this instance, the researchers used keratin from leftover Agora wool that was being used in manufacturing.

The wool can be made using 3D-printing, into any shape – programmed with a form that it then ‘remembers’.

This development could help reduce textile waste, and open up materials to new uses.

“With this project, we have shown that not only can we recycle wool but
