Senstar (SNT) SimplyvWall Street report from October 2, 2023 BEFORE all hell broke loose in Israel. The company is based in Israel and has leading-edge intrusion detection technology. Wonder if the Israelis were using them before. Someone sure noticed the stock today. Wow.

— These tests could soon become a valuable addition to current cancer screening toolsIn 2020 (the most recent year for which federal U.S. incidence data are available), 1,603,844 new cases of cancer were reportedopens in a new tab or window and 602,347 people died of cancer. Despite substantial progress in prevention, screening, and treatment for more of its common forms, cancer remains the second leading cause of deathopens in a new tab or window in the U.S. (2022), surpassed only by heart disease. A stated goal of Healthy People 2030opens in a new tab or window reads, "Reduce new cases...

In the late 1950s, dentist and US Navy Capt. Kirk C. Hoerman, then a young man in his 30s, attempted to answer a bold question: Might the saliva of prostate cancer patients have different characteristics from that of healthy people? Could it contain traces of a disease that’s so far away from the mouth? Without wasting more of their own saliva on elaborate discussion, Hoerman and his colleagues from the department of dental research at the Naval Training Center in Great Lakes, Illinois, got down to work. They analyzed samples from more than 200 patients and healthy controls, and found...

Meghan Puglia, a neurologist at the University of Virginia, is working to detect autism in babies much earlier. Her goal is to help children with autism achieve optimal outcomes through earlier diagnosis. “We know early intervention is the strongest predictor of optimal outcomes for kids with autism,” Puglia said. Right now, she says the earliest age that autism can be diagnosed is at 18 months. “All babies, before they leave the hospital, get a hearing screening and metabolic tests. There is no screening for autism until the baby is toddling around and starting to talk,” Puglia said. Each week, Puglia...

The earlier cancer is detected, the better the chance of successful treatment. Pancreatic cancer, for example, is one of the deadliest cancers. Physicians rarely find the tumor before it causes symptoms, and by then, it has spread to other tissues. For the few patients diagnosed before the cancer spreads, the 5-year survival rate is almost 60%; otherwise, the survival rate is less than 5%. “Pancreatic cancer has the lowest five-year relative survival rate of all major cancer killers and is the only one for which both the incidence and death rates are increasing,” explained Dr. Andrew Lowy, clinical director for...

In this participatory session, you will learn how to tell when someone is lying. Really. As a former CIA Officer with more than 20 years of experience in interviewing, interrogation and polygraph examination, Susan has seen her share of truth avoiders. She has, in fact, developed behavioral screening programs that are used by the federal government. ...

Scientists at the University of Veterinary Medicine Hanover have found that trained sniffer dogs could be used to detect COVID-19 in human samples with a relatively high rate of accuracy, a study published on Thursday revealed. Eight sniffer dogs from the German Bundeswehr were trained for only a weekto distinguish between the mucus and saliva of patients infected with coronavirus and non-infected individuals. The dogs were then presented with positive and negative samples on a random basis by a machine. The animals were able to positively detect SARS-CoV-2 infected secretions with an 83% success rate, and control secretions at a...

Via Nate Silver, most of us are way out of our depth in trying to understand this stuff. I feel more out of my depth each day as I try to reconcile the increasingly hair-raising projections being made by most epidemiologists with the implications of the Oxford model of the disease, which speculates that asymptomatic infections are much more common than anyone realizes. But I’m going to try anyway.If Oxford is right, it means two things are likely true and they’re both welcome news. One: The case fatality rate is much lower than we’ve assumed. A large number of...

In a three-year project that launches this month, Natalia Nikolova, an electrical and computer engineering professor, will be working with researchers from Canada and Ukraine to design devices that use radar signals to analyze the materials carried by a person. The technology — which can be built into a military vest or a tripod, for example — is designed to emit radio waves that reach a person. The waves that bounce back will carry unique information that can be analyzed by computers. "This radio wave, as we say in radar terminology, interrogates the person and it carries back information from...

Visualizing the anatomical vessel networks plays a vital role in physiological or pathological investigations. However, identifying the fine structures of the smallest capillary vessels via conventional imaging ways remains a big challenge. Here, the room temperature liquid metal angiography was proposed for the first time to produce mega contrast X-ray images for multi-scale vasculature mapping. Gallium was used as the room temperature liquid metal contrast agent and perfused into the vessels of in vitro pig hearts and kidneys. We scanned the samples under X-ray and compared the angiograms with those obtained via conventional contrast agent--the iohexol. As quantitatively proved by...

Tomorrow the 460th Space Wing at Buckley Air Force Base will celebrate the 40th anniversary of the first launch of the Defense Support Program (DSP) satellite. It was the beginnings of a satellite constellation that has been providing space-based infrared missile warning to our nation's leaders for four decades. On, Nov. 6, 1970 the launch of the maiden DSP spacecraft from Cape Canaveral, Fla. was accomplished. During the last several decades, a dedicated team of scientists, engineers, acquisition specialists, civilian contractors and space professionals has ensured that the DSP system performed better than advertised and lasted much longer than designed....

Russia could build a satellite for the detection and tracking of submarines from space, a defense industry spokesman said on Thursday. Vladimir Boldyrev, of the Kosmonit science and technology center, said the group had developed a space satellite module that could carry out remote sensing of the sea and "detect submerged submarines." "Hopefully, it will be tested in space as early as 2011," he said, adding that work on the module started over a decade ago. He offered no indication as to when the new satellite would enter service with the Russian Armed Forces. Boldyrev added that the dual-use module...

The creature that’s expected to inherit the Earth following a nuclear holocaust might also be well suited to help prevent man’s atomic self-destruction. Researchers at Texas A&M University’s Nuclear Security Science and Policy Institute have attached radiation sensors to the backs of cockroaches. They hope public-safety officials will one day send the souped-up insects into situations that are too risky for humans. “Cockroaches really are the perfect medium for this,” says William Charlton, an associate professor of nuclear engineering at the university and a principal investigator on the project. “They can go for extraordinarily long periods of time without food....

ARLINGTON, Va., Oct. 22, 2009 – A California Army National Guard supply noncommissioned officer diagnosed with breast cancer is cancer-free today, and she credits early detection with her new lease on life. California Army National Guard Staff Sgt. Elizabeth Cowie credits early detection with remaining cancer-free two years after being diagnosed with breast cancer. U.S. Army photo  (Click photo for screen-resolution image);high-resolution image available. With a yearlong deployment right around the corner when she got her diagnosis, Army Staff Sgt. Elizabeth Cowie opted for an aggressive treatment plan that would get her back to her unit quickly. “As soon as people...

January 15, 2007 The Improvised Explosive Device (IED) is relatively new to the theatre of war as a mainstream weapon. It was first used en masse by Belarusian guerillas against German supply trains during World War II. Since then, explosive devices have been used to great effect in a number of asymmetrical conflicts. The IED has achieved main weapon status in the current Iraq War, and as usual, some ingenious improvisations have evolved to overcome them. As ludicrous as it may for a soldier in body armour to be carrying a weapon such as the one pictured, that’s just what...

May 12, 2006 — Americans by nearly a 2-1 ratio call the surveillance of telephone records an acceptable way for the federal government to investigate possible terrorist threats, expressing broad unconcern even if their own calling patterns are scrutinized. Lending support to the administration's defense of its anti-terrorism intelligence efforts, 63 percent in this ABC News/Washington Post poll say the secret program, disclosed Thursday by USA Today, is justified, while far fewer, 35 percent, call it unjustified. Indeed, 51 percent approve of the way President Bush is handling the protection of privacy rights, while 47 percent disapprove — hardly a...

In an attempt to tackle gun crime in the UK, researchers from Loughborough University are developing an innovative identification system that will use CCTV cameras to spot individuals carrying concealed firearms. Starting in June, the three-year multi-environment deployable universal software application (Medusa) project aims to develop intelligent software that can detect a person carrying a concealed weapon in real time. While it is difficult to predict if someone is carrying a gun before crime occurs, Professor Alastair Gale, head of Loughborough University's Applied Vision Research Centre and leader of Medusa, said there are a number of cues the CCTV operator...

Underwater Sub Detection: SBIR Tries to Think Like a Shark Posted 06-Jul-2005 05:10 DID has covered evolving US anti-submarine warfare strategy before, including the growing importance of dealing with super-quiet diesel-electric submarines in shallow-water littorals.In response, one of the early-stage Small Business Innovation Research (SBIR) approaches involves thinking entirely outside the sonar box. We talk about "submariner dolphins" - but maybe the creature they really need to emulate is the shark. Unlike dolphins, sharks don't use sonar. Instead, they rely on both an acute sense of smell and on jelly-filled canals that pick up on the tiny electrical charges a...

Scientists: Tsunami Could Hit West Coast Tsunami scientists and public safety officials are closely watching an earthquake-prone nation with thousands of miles of crowded coastlines for signs of an imminent disaster. Indonesia? Japan? Try the United States. Experts say the West Coast could experience a calamity similar to the one they have been watching unfold half a world away. "People need to know it could happen," said geologist Brian Atwater of the U.S. Geological Survey. Scientists say grinding geologic circumstances similar to those in Sumatra also exist just off the Pacific Northwest coast. They are a loaded gun that could...

The Lawrence Livermore labs have developed a cell phone-intended for general issue to police officers and selected first responders-which can detect radiation in the areas they cover during normal patrol duties. A GSP device is built in,and,when the cell phone detects a radioactive source, it "phones in" to a central reporting area,telling it where the suspicious material was found. The Livermore invention is quite a bit larger than a typical cell phone,and considerable thought would have to be given to deployment,as projected cost is $1000. per unit. It is a bit less sensitive than existing devices,but a lot cheaper to...
