A new algorithm could help detect landslides in minutes

A new algorithm could help detect landslides in minutes

Landslides can be truly devastating, killing people and animals that can’t get out of the way in time and washing away property. Landslides generally occur during earthquakes, volcanic eruptions, or massive rainfall that make a sloped section of land like a cliff unstable. Now, a team from the University of Alaska Fairbanks (UAF) have developed a new method that could be used to remotely detect large landslides within minutes and tell if the slide is a tsunami hazard. Their method is described in a study published February 9 in the journal The Seismic Record. [Related: California wildfires may give way to massive mudslides.] Monitoring Alaska’s glacial fjords for danger The study cites a 2015 landslide that sent 100 million cubic yards of rock into Alaska’s Taan Fjord. It generated a tsunami that stripped vegetation as high as 620 feet above the waterline.  In response, the team helped develop a prototype system capable of real-time detection that has been in place since August 2023 around the Barry Arm section of Prince William Sound. The system uses …

Scientists can now detect underground weapon tests with 99% accuracy

Scientists can now detect underground weapon tests with 99% accuracy

Storax Sedan shallow underground nuclear test by the United States, used for a cratering experiment. 6 July 1962 (GMT), Nevada Test Site Yield: 104 kt. The main purpose of the detonation was to asses the non military dimension of a nuclear explosion. (CREDIT: Creative Commons) A “groundbreaking” scientific advancement may soon put an end to clandestine underground nuclear tests, offering a ray of hope in global efforts towards nuclear non-proliferation. Earth scientists and statisticians have announced a significant leap in their ability to distinguish nuclear explosions from other seismic activities with an impressive accuracy rate of 99 percent, as reported in a study recently published in Geophysical Journal International. Lead author Dr. Mark Hoggard from The Australian National University (ANU) explains the challenge they faced: “The explosion goes off and you have all this energy that radiates out, which can be measured on seismometers. So, the science problem becomes how do we tell the difference between that and a naturally-occurring earthquake?” This dilemma was underscored seven years ago when existing methods failed to confirm North …

How to detect poisoned data in machine learning datasets

How to detect poisoned data in machine learning datasets

Almost anyone can poison a machine learning (ML) dataset to alter its behavior and output substantially and permanently. With careful, proactive detection efforts, organizations could retain weeks, months or even years of work they would otherwise use to undo the damage that poisoned data sources caused. What is data poisoning and why does it matter? Data poisoning is a type of adversarial ML attack that maliciously tampers with datasets to mislead or confuse the model. The goal is to make it respond inaccurately or behave in unintended ways. Realistically, this threat could harm the future of AI. As AI adoption expands, data poisoning becomes more common. Model hallucinations, inappropriate responses and misclassifications caused by intentional manipulation have increased in frequency. Public trust is already degrading — only 34% of people strongly believe they can trust technology companies with AI governance. Examples of machine learning dataset poisoning While multiple types of poisonings exist, they share the goal of impacting an ML model’s output. Generally, each one involves providing inaccurate or misleading information to alter behavior. For …

Manufacturing giant develops revolutionary system to detect counterfeit art | Art theft

Manufacturing giant develops revolutionary system to detect counterfeit art | Art theft

Revolutionary technology invented to identify counterfeit spare parts in the car and aerospace industries has now been adapted to detect counterfeit works of art. The developers of the “optical recognition system” claim they have created “tamper-proof digital fingerprints” of paintings and sculptures that could, for example, enable museums to spot – within seconds – whether an original work has been swapped with a fake. A German museum recently fell victim to such crime. An employee replaced three paintings with fakes, selling the originals to treat himself to a Rolls-Royce and other luxuries. The technology, called Origify, was developed by Bosch in 2017 to stop the trade in fake spare parts for cars and planes. The German manufacturing company is the biggest supplier for the car industry. Until developing Origify, it had struggled to combat counterfeiting and other fraud in manufacturing and the replacement parts market where, with unregulated networks of dealers and repair shops, it is easier for counterfeiters to bring in illegal products. Such counterfeit parts include exhaust sensors that are too small to …

Groundbreaking blood test could detect Alzheimer’s Disease 15 years in advance

Groundbreaking blood test could detect Alzheimer’s Disease 15 years in advance

As the global population continues to age, health experts are gearing up for a surge in age-related diseases. (CREDIT: Creative Commons) As the global population continues to age, health experts are gearing up for a surge in age-related diseases, with Alzheimer’s disease looming as a significant concern. Detecting and diagnosing Alzheimer’s early has never been more critical, as new treatments show the most promise when administered in the disease’s early stages. Unfortunately, the current diagnostic methods, such as PET imaging and lumbar punctures, are either too expensive or invasive for most individuals, leaving a significant number of cases undiagnosed. In a groundbreaking study recently published in JAMA Neurology, researchers have unveiled a promising and more accessible diagnostic tool that utilizes blood samples and detects Alzheimer’s up to 15 years before symptoms emerge. The test could potentially revolutionize the screening and monitoring of this neurodegenerative condition. The study, a collaborative effort between the University of Gothenburg in Sweden and ALZPath, a company specializing in blood-based Alzheimer’s tests for research purposes, aimed to evaluate the efficacy of …

UK scientists to test ‘breakthrough’ blood test which could be used to detect brain tumours | UK News

UK scientists to test ‘breakthrough’ blood test which could be used to detect brain tumours | UK News

UK scientists are to carry out studies on a new “breakthrough” blood test which could be used to detect certain types of brain cancer. Described as a “liquid biopsy”, the test, believed to be a world-first, could reduce the need for invasive and risky surgery currently needed to diagnose some brain tumours. The tests could also lead to an earlier diagnosis, which in turn could speed up treatment and potentially increase survival rates for patients with one of the deadliest forms of brain cancer, experts say. Patients with inoperable brain tumours could particularly benefit – because an early diagnosis would allow them to start treatments such as chemotherapy or radiotherapy as soon as possible. Scientists in the UK have already studied the tests and are now hoping to conduct larger trials. If successful, the “inexpensive” and “patient-friendly” test could be rolled out to health services within two years, experts say. What is the test? The TriNetra-Glio blood test, developed by Datar Cancer Genetics, works by isolating cells that have broken free from the tumour and …

Zoe Care uses existing Wi-Fi signals to detect falls in care homes

Zoe Care uses existing Wi-Fi signals to detect falls in care homes

Fall detection and autonomy for the elderly is front-and-center at CES in Las Vegas this year. Cherish Health introduced the $300 Serenity appliance that uses radar to cover a whole house with fall detection powers. Zoe Care is taking a different approach, by using existing Wi-Fi signals (and the way our bodies change how Wi-Fi reception works) to detect humans and their activities. Using Wi-Fi signals is a pretty cool, non-intrusive solution that addresses the key issues of privacy and ease of use that often plague conventional remote monitoring technologies. The device doubles as a smart plug, and uses a sensor to gather and analyze Wi-Fi signals. If a fall is detected, these signals are translated into alerts on a mobile application. Covering up to 800 sq. ft., just one device can secure multiple rooms or even an entire floor, making it an efficient, cost-effective solution. “We’re currently beta testing with nursing homes. A consumer version will be available by the end of the year. The fall detector will be offered as a subscription service, …
