'Broken heart syndrome' has increased during the Covid-19 pandemic, small study suggests



A study published Thursday found a significant increase in "broken heart syndrome" at two Ohio hospitals among some patients who don't have coronavirus, suggesting that the physical, social and economic stressors from the pandemic are taking a physical toll.

Stress-induced cardiomyopathy or Takotsubo syndrome -- which is often called "broken heart syndrome" -- occurs when the heart muscles weaken, leading to chest pain and shortness of breath. It presents like a heart attack, but is triggered by stressful events, not blockages in the bloodstream.

U.S. Air Force Launches Three-Year Fielding Plan For Skyborg Weapons


The next combat aircraft to enter the U.S. Air Force inventory will not be a manned sixth-generation fighter or even the Northrop Grumman B-21.

By fiscal 2023, the Air Force expects to deliver the first operational versions of a new unmanned aircraft system (UAS) called Skyborg, a provocative portmanteau blending the medium of flight with the contraction for a cybernetic organism.

This Iowa Town Is Building An Open Access Fiber Broadband Network. Google Fiber Is Its First Customer


West Des Moines, Iowa this week announced that it would be building a massive, open access fiber network. The city is one of roughly 750 towns and cities that, frustrated by high prices, limited competition, and patchy availability of US broadband, have decided to instead build their own networks. Well, assuming that AT&T and Comcast haven't bribed your state officials to pass laws banning such efforts yet.

US Army's gravity-defying aluminum panel purifies water with sunlight


Providing clean drinking water in regions where the resource is scarce is a huge challenge, and one that we’re seeing plenty of inventive solutions to. A research team from the US Army and the University of Rochester is throwing a new possibility into the mix, showing off a “superwicking” aluminum panel that uses solar power to purify water with great efficiency.

Solar power has proven a popular choice when it comes to powering low-cost water purifiers, with sunlight long known to destroy waterborne pathogens.

Tesla Model 3 resale value is over five times better than industry average: study


Teslas have garnered a reputation for many things, and having a great resale value is one of them. This was recently highlighted in a study conducted by car search engine iSeeCars.com, which analyzed over 6.9 million car sales to identify which vehicles experienced the most and least depreciation in the past three years. As it turns out, the Tesla Model 3 is able to retain its value over five times better than other EVs in the market.

Verizon Has To Walk Back Bogus 5G Coverage Claims


Reality is... something different. One recent study by OpenSignal found that users in the real world are able to obtain a Verizon 5G signal about 0.4% of the time, largely because the millimeter wave spectrum Verizon is using doesn't provide very good range, and can't penetrate buildings particularly well. Even in the places that Verizon advertises as having widespread coverage -- like sports stadiums -- routinely see patchy availability.

U.S. TikTok Hysteria Teeters Toward The Idiotic


It was just the latest example of how, upon closer inspection, much of the hysteria surrounding TikTok isn't based on much of anything... substantive. There's been no limit of pearl clutching from the Trump administration and its allies about the app, but when it comes to actual supporting evidence to justify an outright ban, there's just not much of it beyond "it's from China."

Study shows how traumatic experiences can leave their mark on a person's eyes


New research by Welsh academics shows that a patient's pupils can reveal if they have suffered a traumatic experience in the past.

Post-traumatic stress disorder can occur when a person has experienced a traumatic event such as a car crash, combat stress, or abuse. They can be left with a greater sensitivity, or hyperarousal, to everyday events and an inability to switch off and relax.
