President Jiang Zemin gets an update on China´s Terfenol-D project. The U.S. Navy spent millions of dollars to develop Terfenol-D in the early 1980s, and intelligence experts estimate that the People's Republic of China (PRC) has devoted extensive resources to try to steal it. Insight has learned that these PRC efforts have paid off. The spy target is an exotic material made up of two types of rare-earth metals called lanthanides, terbium and dysprosium, plus iron (FE). The NOL stands for Naval Ordnance Laboratory. Hence the name Terfenol-D. Those who have worked with this exotic material call it almost magical....

The Secret Service may have violated federal records laws by failing to preserve data - including information related to the Jan. 6 Capitol attack - after it had been requested by investigators, the House committee investigating the riot said Wednesday. The condemnation came after the panel subpoenaed the agency following an allegation from the inspector general at the Department of Homeland Security (DHS), which oversees the Secret Service, that it had “erased” the texts during a device replacement program. “We have concerns about a system migration that we have been told resulted in the erasure of Secret Service cell phone...

Long Islanders won’t like the sound of this. Hundreds of people have signed a petition to rename the Long Island Sound the “Gulf of Connecticut” in favor of New York’s northern neighbor. Inspired by President Trump’s recent change of the Gulf of Mexico to the Gulf of America, the call for the change comes as the nation “has long ignored the greatness of CONNECTICUT!” William Yoxall wrote on his Change.org page, which now has close to 750 signatures. “Such as being the pizza capital of the WORLD!!!” Yoxall said, a nod to the loopy Connecticut lawmakers who symbolically declared their...

A mysterious sound heard booming from deep under the ocean waves has finally been traced to a fascinating source. First recorded in 2014 in the west Pacific, the "biotwang" is actually the call of the Bryde's whale (Balaenoptera brydei) traveling long distances in the open ocean. What's more, the techniques used to identify the sound have led to the development of a new tool for understanding whale populations and how they move about in and inhabit Earth's enigmatic seas. "Bryde's whales occur worldwide in tropical and warm temperate waters, but their population structure and movements are not well understood," writes...

I have a question for LINUX users: We ran updates for LINUX last night, and when I turned on the computer this morning, I had no sound. It doesn't seem to be a problem with the speakers, and my Bluetooth ear buds are still getting sound when I listen to various YT sites; but nothing is coming out of the computer/speakers otherwise. Has anyone experienced this? We have Mint, I think it's 21. We have never had an issue like this. Thanks to anyone who has time to respond.

In older adults, even mild impairment can affect the brain. But there are simple ways to reduce the harm.Adults over age 65 who experience vision loss have a nearly 50 per cent increased risk of developing dementia. If those vision problems are corrected, that risk drops dramatically. That’s according to a report published by an international commission focused on dementia prevention, which added vision impairment to its list of 14 total modifiable risk factors for dementia. Other risk factors include smoking, diabetes, social isolation and hypertension. Experts say the addition of vision loss is not a surprise, particularly given that...

Early-stage trials in Alzheimer's disease patients and studies in mouse models of the disease have suggested positive impacts on pathology and symptoms from exposure to light and sound presented at the gamma band frequency of 40 Hz. A new study zeroes in on how 40Hz sensory stimulation helps to sustain an essential process in which the signal-sending branches of neurons, called axons, are wrapped in a fatty insulation called myelin. Often called the brain's "white matter," myelin protects axons and insures better electrical signal transmission in brain circuits. Said Li-Huei Tsai,"This study shows that it's not just gray matter, but...

Your morning alarm clock might not just be annoying. It could be raising your blood pressure, putting you at greater risk for adverse cardiovascular events, such as stroke and heart attack, according to research. Yeonsu Kim studied how being forced awake contributes to morning blood pressure surge, an increase in blood pressure that happens when people move quickly from being asleep to awake. Kim studied 32 participants over two days. The first night, they were told to awaken naturally, without an alarm. The second night, they were instructed to set an alarm to awaken them after only five hours of...

John Kerry’s call to end all coal-powered electricity generation is “silly” and “self-destructive,” writes former Speaker of the House Newt Gingrich, and “makes the United States look delusional.” In his punchy essay, Gingrich insists that it is “not hyperbole or exaggeration” to call John Kerry “crazy,” since the word crazy means “marked by thought or action that lacks reason.” Mr. Kerry’s failing mental state was on full display during his recent “emotional speech” to the United Nations Climate Change Conference, where he made a plea to “end all coal burning power plant construction in the entire world.”

Presales for Angel Studios’ Sound of Freedom have skyrocketed to $10 million ahead of the film’s July 4th opening across 2,600 locations. According to Deadline, the studio is "spotting a 6-day $20M start which is extremely impressive for a non-major studio adult thriller," and over one million tickets have been bought for the based-on-a-true-story film following a former Homeland Security agent, played by Jim Caviezel, who rescues abducted children around the world.

I have hearing loss. I get by with earbuds and subtitles, but I could use help. I imagine many people could benefit from this. I believe it’s possible to boost volume, because I have VLC Media Player, which boosts volume enormously. However, it only seems to work on DVDs. So, I still need help in boosting volume on internet videos and streams. An internet search yielded the BOOM 3D add-on, but reviews say its Volume Booster only works in Macs. My laptop is a Dell Inspiron 15-3501, running Windows 11. I’ve searched Windows Settings and Registry Editor for help, without...

With many people working remotely, everybody should by now know how to behave when in a Zoom or Microsoft Teams meeting. Your camera picks up every move even when you think no one is watching, and your microphone can catch the faintest of sounds. Most people assume that muting their computer’s microphone gives them total privacy. That should be the case, but it’s not.Read on to find out how your microphone is sneakily still listening to everything you say.Here’s the backstoryResearchers at the University of Wisconsin-Madison discovered that your device’s microphone continues to listen even after hitting the mute switch.While...

Audio tape released by former US official reveals the association of mysterious sound with Havana syndrome. The audio recording was made by a former US official in Cuba.On Sunday, a former US official released an audio tape with CBS News that purports to demonstrate a sound linked to Havana Syndrome, a strange sickness with unknown origins that has sickened US officials, warriors, and intelligence professionals.The former official, who did not want to be identified, said he became sick at his house in Havana, Cuba, and informed CBS’ ’60 Minutes’ about it. He reported the sound as “just loud sound” which...

The D.C. National Guard chief on Wednesday told lawmakers he would have “immediately” activated his forces to assist U.S. Capitol Police on Jan. 6 if his authority had not been restricted by the Pentagon. “I would have sent them there immediately as soon as I hung up,” Commanding Gen. William Walker told lawmakers on the Senate Rules Committee and Homeland Security and Governmental Affairs Committee at a hearing evaluating the security breakdown that occurred when a pro-Trump mob attacked the Capitol. “My next call would have been to my subordinate commanders, to get every single guardsman in this building and...

This set of sounds from the surface of Mars were recorded by the microphone on the side of NASA’s Perseverance Rover on Feb. 20, 2021. In the first set, sounds from the rover itself dominate. In the second set, the sound was filtered to make sounds from Mars more audible. You can hear a little wind in the second set. This is the first time a Mars rover has been equipped with a microphone.

Can anyone explain this? https://youtu.be/yldjUctBLfs  

How did the #Ancient Civilisations cut and shape such intricate stonework like we see in #Ancient Egypt? How were holes seemingly drilled through solid granite? How did the #Incas create walls with perfectly connecting blocks of stone? Did they use traditional tools? Did they harness the power of the sun as I explained in a previous video? Or did they know the secrets of sound and this was a form of ancient high technology?

Sound has negative mass, and all around you it's drifting up, up and away — albeit very slowly. That's the conclusion of a paper submitted on July 23 to the preprint journal arXiv, and it shatters the conventional understanding that researchers have long had of sound waves: as massless ripples that zip through matter, giving molecules a shove but ultimately balancing any forward or upward motion with an equal and opposite downward motion. That's a straightforward model that will explain the behavior of sound in most circumstances, but it's not quite true, the new paper argues. A phonon — a...
