No Need To Fear Universe Ending In ‘Collision With Bubble Of Nothingness’(False Vacuum Collapse Of Higgs Field)

Posted by in category: existential risks

This is an article in New Scientist that’s being shared in social media which says it’s a new caclulation of the future of the Universe according to the theory of false vacuum. It’s scaring many people because when you read it as far as it goes, before you have to pay to read, it doesn’t give a timeline, so they think it could happen any moment. Also, because it says “there’s a chance” that it has already collapsed in a distant corner of the cosmos. I’m writing this as part of a series of posts to help people scared of false or exaggerated doomsdays, which often get to the top of Google, Apple News and Facebook trending and are read by many people who have no idea how to take them including children as young as 14 and sometimes much younger. They can get very scared about these stories, have panic attacks and are sometimes suicidal because they can’t bear the fear.

Seattle makes history with electric garbage truck

Posted by in categories: energy, transportation

Despite this, electric garbage trucks are still few and far between. BYD’s main competitor is Motiv Power Systems, which has sold small fleets of class 8 side-loading garbage trucks to Los Angeles and Sacramento, California. Wrightspeed, which was also making hybrid-electric garbage trucks—featured in this article from 2015—appears to have gone dormant, despite a contract to supply the New Zealand cities of Auckland and Wellington. And recently, Volvo announced a battery electric garbage truck, the FE Electric, although it appears to be limited to the European market.

‘Einstein Was Right: You Can Turn Energy Into Matter’

Posted by in categories: information science, nuclear energy, particle physics

E=m c

Albert Einstein proposed the most famous formula in physics in a 1905 paper on Special Relativity titled Does the inertia of an object depend upon its energy content?

Essentially, the equation says that mass and energy are intimately related. Atom bombs and nuclear reactors are practical examples of the formula working in one direction, turning matter into energy.

Physicists Created Quantum Structures That May Have Birthed Dark Matter

Posted by in categories: cosmology, quantum physics

Some cosmologists have predicted the existence of “walls bounded by strings” in the aftermath of the Big Bang, and now a team of physicists have created these quantum structures on Earth for the first time.

Air Force Treating Wounds With Lasers and Nanotech

Posted by in categories: biotech/medical, military, nanotechnology

Forget stitches and old-school sutures. The Air Force is funding scientists who are using nano-technology and lasers to seal up wounds at a molecular level. It might sound like Star Trek tech, but it’s actually the latest in a series of ambitious Pentagon efforts to create faster, more effective methods of treating war-zone injuries. Last \[…\].

Scientists create new standard genome for heavily studied worm

Posted by in categories: biotech/medical, genetics, life extension

A new Cornell University-led study finds that the genome for a widely researched worm, on which countless studies are based, was flawed. Now, a fresh genome sequence will set the record straight and improve the accuracy of future research.

When scientists study the genetics of an organism, they start with a standard genome sequenced from a single strain that serves as a baseline. It’s like a chess board in a chess game: every board is fundamentally the same.

One model organism that scientists use in research is a worm called Caenorhabditis elegans. The worm—the first multicellular eukaryote (animal, plant or fungus) to have its genome sequenced—is easy to grow and has simple biology with no bones, heart or circulatory system. At the same time, it shares many genes and molecular pathways with humans, making it a go-to model for studying gene function, drug treatments, aging and human diseases such as cancer and diabetes.

Bipolar disorder may be linked to Parkinson’s disease

Posted by in categories: biotech/medical, health, neuroscience, sex

People who have bipolar disorder may be more likely to later develop Parkinson’s disease than people who do not have bipolar disorder, according at a study published in the May 22, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology.

“Previous studies have shown a relationship between depression and Parkinson’s disease, but few studies have looked at whether there is a relationship between and Parkinson’s,” said study author Mu-Hong Chen, MD, Ph.D., of Taipei Veterans General Hospital in Taiwan.

For the study, researchers examined a national Taiwanese health database for people were diagnosed with disorder between 2001 and 2009 and who had no history of Parkinson’s disease, for a total of 56,340 people. They were matched with 225,360 people of the same age, sex and other factors who had never been diagnosed with bipolar disorder or Parkinson’s disease as a control group. Then the two groups were followed until the end of 2011.

Behold the mayo: Experiments reveal ‘instability threshold’ of elastic-plastic material

Posted by in categories: engineering, materials

Arindam Banerjee, an associate professor of mechanical engineering and mechanics at Lehigh University, studies the dynamics of materials in extreme environments. He and his team have built several devices to effectively investigate the dynamics of fluids and other materials under the influence of high acceleration and centrifugal force.

One area of interest is Rayleigh-Taylor instability, which occurs between materials of different densities when the density and pressure gradients are in opposite directions creating an unstable stratification.

“In the presence of gravity—or any accelerating field—the two materials penetrate one another like ‘fingers,’” says Banerjee.
