    *sigh* OK. On Friday, 6/26, I underwent an upper GI endoscopic exam for my Hemo/oncology specialist, to check for varices, bleeders, portal hypertension, etc. After I came out of the fog, they unhooked all with wires, tubes, etc., and allowed me to dress. The endo doc came by and said, with the exception of some 'changes' due to GERD (which has been treated for years), nothing was amiss. In the midst of shaking the fuzz out of my ears, they mentioned that I'd have a follow-up for it. Here's where it gets good: They called me this afternoon to confirm...

    More than half a century ago a fellow grad student invited me into his laboratory to show me his doctoral research. He introduced me to the science of animal reflexes. A novel stimulus induces in an animal, however briefly, a freeze reaction. This is called an “orienting reflex.” What happens next depends on the animal’s response to the potential threat. If the novel stimulus does not seem to be a threat the animal gradually relaxes. Repeats of this type of stimulus gradually habituate its orienting reflex so that the animal, in effect, learns to ignore this particular stimulus. On the...

    This is the frightening moment a bridge with heavy traffic moved up and down like waves after reportedly being hit by high winds. Shocking footage shows the Humen Bridge, which spans across the Pearl River in southern Chinese province Guangdong, shaking dramatically while being jam-packed by cars. Local authorities have temporarily shut down the traffic link. They said the structure wobbled after being hit by whirlwinds, according to the press.

    The Harris County Toll Road Authority plans to take a three-week pause in construction on the new Houston Ship Channel Bridge along the Sam Houston Tollway so engineers can agree on a solution to a possible design flaw found nearly 20 months into the project. The $1 billion bridge — the costliest infrastructure project in the county’s history — was designed by the Dallas office of FIGG Bridge Group. The company, based in Florida, came under scrutiny when its Tallahassee office designed a pedestrian bridge that collapsed in February 2018 at Florida International University, killing six. FIGG and its consultants...

    HOUSTON – Following 20 months of construction of the new Ship Channel Bridge along the Beltway 8, the county has issued a pause. Harris County Commissioner Adrian Garcia said the decision was made following the discovery of a design flaw with part of the bridge. “I want to make sure that we are doing everything on behalf of public safety to ensure that everything is well,” Garcia said. “This was obviously concerning and alarming for me." John Tyler, the deputy director of engineering with the Harris County Toll Road Authority and in charge of the project, said the flaw was...

    The strange flying objects have been spotted near F.E. Warren Air Force Base in Wyoming, which houses enough nuclear intercontinental ballistic missiles to wipe out several cities. For weeks, mysterious unidentified flying objects over the Eastern Plains region of Colorado have vexed residents, law enforcement, the military, and state and federal officials. Those who see them say they appear in the night sky, often several at a time, their locations marked by the light they emit. Audibly buzzing, they hover and maneuver in precise formations. The mystery of their origin has gripped Colorado, where news of a sighting makes near-daily...

    I’m as much a Sci-Fi fan as most anyone. I’ve read my fair share of Orson Scott Card books, seen all the Men in Black movies, think it’s a travesty that Firefly got canceled, and have sat through every cringy second of every lame attempt to improve on the original Star Wars trilogy, but until the past few months, I’d never seriously considered even the remotest possibility that humans may not be alone, at least on this planet and in this solar system.  But here we are, and if anything should unite humanity in an era seemingly as divided as...

    The last time the National Transportation Safety Board came down hard on engineering and construction was in 2007. That year, the board delivered reports on the collapse of the I-35 Highway Bridge in Minneapolis that killed 13 people, and on a ceiling collapse in a Boston Central Artery tunnel that killed one motorist. Both involved completed structures. With its final investigation findings, the board also made recommendations for new standards and procedures and quality control. NTSB's report on last year’s Miami bridge collapse at Florida International University in mid-construction, which killed five motorists and one construction worker, has similar recommendations....

    Wilmington, North Carolina renews deal with red light camera contractor that violated state engineering laws. The Wilmington, North Carolina City Council last week signed a red light camera contract renewal despite protests that the state had found the for-profit camera contractor in direct violation of the law. American Traffic Solutions (ATS, now known as Verra Mobility) was found to be practicing engineering without a license by the North Carolina Board of Examiners for Engineers and Surveyors last year. The company has yet to remedy the violation, according to the city traffic engineer. Todd Platzer, a local resident, raised the issue...

    The aftermath of two crashes of Boeing 737 Max jets shortly after takeoff has led to the global grounding of the airplane. Boeing has been forced to cut production, and even so, undelivered planes are piling up. Big buyers like Southwest American Airlines have been forced to cancel flights during their peak time of year as a result of taking their 737s off line. American lengthened its 737 grounding to June 5 and Southwest, to August 5 [Update: American sent a notice to American Aadvantage members that the grounding would last through August 19]. Even though Boeing is scrambling to...

    A £2billion project to confine the leaking of radioactive debris at the Chernobyl nuclear plant has been unveiled. The structure – which took nine years to build – was constructed to secure the molten reactor core and 200 tons of radioactive material at the site. Officials have described the shelter as the largest moveable land-based structure ever built, with a span of 257 metres and a total weight of over 36,000 metric tons. Reactor Number 4 at the plant in what was then Soviet Ukraine exploded and burned on April 26, 1986, spewing radiation across Europe in the world's worst...

    A subsea tunnel across the Strait of Belle Isle is back in conversation once again after a report was tabled this month in Ottawa. The federal government’s standing committee on transport, infrastructure, and communities is now calling on the federal government to work with the provinces of Newfoundland and Labrador and Quebec, as well, as the private sector, to build a fixed link across the Strait of Belle Isle and complete Route 138 along the Quebec Lower North Shore. The tunnel would link Point Amour in Labrador to Yankee Point on the Great Northern Peninsula in Newfoundland. The project would...

    AUBURNDALE — Florida has one of the world’s most famous asphalt ovals in the Daytona International Speedway. A slightly smaller track recently completed in Auburndale won’t draw massive crowds for races, but it’s part of a project that could hasten the day when self-driving vehicles take over the roads. Crews finished laying asphalt for the 2¼-mile oval — phase one of SunTrax — in early May, and construction will begin in the coming months on infield elements designed for the development and testing of connected and autonomous vehicles. The second phase of SunTrax, a project overseen by Florida’s Turnpike Enterprise...

    February 20, 2019 America’s STEM Crisis Threatens Our National Security By Arthur Herman On October 4, 1957, a steel sphere the size of a beach ball and bristling with four radio antennae circled the Earth in eight minutes. Dubbed “Satellite-1,” or “PS-1” (Prosteyshiy Sputnik-1) by its Soviet fabricators, it was the first artificial Earth satellite. The Soviets had launched it into an elliptical low Earth orbit, where it stayed for three weeks before its batteries died. Then it continued silently in a decaying orbit for another two months before burning up in the atmosphere. Its radio signal pulses were easily...

    Airplanes are becoming far too complex to fly. Pilots are no longer needed, but rather computer scientists from MIT. I see it all the time in many products. Always seeking to go one unnecessary step further, when often old and simpler is far better. Split second decisions are........needed, and the complexity creates danger. All of this for great cost yet very little gain. I don’t know about you, but I don’t want Albert Einstein to be my pilot. I want great flying professionals that are allowed to easily and quickly take control of a plane!
