There are three dimensions in the known universe. Fiction authors like to call time a dimension but it really isn't, it is just a way to look at the other three. Even if you don't remember what you ate for lunch yesterday the universe knows you were 2 millions miles away from where you are right now when you at it. Since everything in the universe was also shifting in chaotic ways there is no way to return and have a different lunch.

Imagine a world where government decided they would mandate and subsidize existing cellular phones. With no incentive to improve, we'd still be using Motorola StarTacs. 

At the very large and very small scale, Newtonian gravity does not work the way it should. The universe should not be expanding and forget trying to explain quantum mechanics.

Trying to detail why electrons can behave as both particles and waves, depending on the experimental context in which they are observed, is challenging. Louis de Broglie, Niels Bohr, Erwin Schrödinger, and David Bohm all tried but used self-consistent yet contradictory interpretations.

A genetic analysis found a single point mutation in the TLR7 gene and then identified other cases of severe lupus where this gene was also mutated. 

Lupus is a chronic autoimmune disease which causes inflammation in organs and joints, affects movement and the skin, and causes fatigue. In severe cases, symptoms can be debilitating and complications can be fatal. The work resulted from whole genome sequencing on the DNA of a Spanish child named Gabriela, who was diagnosed with severe lupus when she was 7 years old. Such a severe case with early onset of symptoms is rare and indicates a single genetic cause.

In a new paper, scholars say depression, anxiety, and other mental health issues are more common than ever before, and that people of color are impacted most.

The data are from surveys, and young people have always felt a need to 'live in important times' and believe everything is different than any other generation faced, but young people today went through an economic meltdown and then a pandemic, with all of the resulting media attention and worry that entailed. The Healthy Minds Network pool was between 2013 and 2021 from 350,000 students at over 300 campuses. 

One of the odder disconnects in western culture is people who claim to care about the environment but will only eat fish that is caught in unsustainable ways - in the wild. I suppose I get the appeal of knowing laborers risked their lives for your food and that farmers in $300,000 tractors don't have the same cachet.(1)

Yet those same people are horrified at the thought of hunting game like rabbit and venison, they want those farmed. Insisting on only wild salmon seems irresponsible. What if we did that about lettuce or strawberries? They'd be expensive and our nutrition would suffer.

As I write these few lines, I am sitting in the nice auditorium at CSIC in Madrid, where I came for a congress that is a bit different to many others that take place around the world at all times. Truth be told, covid-19 took a big hit on the organization of these events, but slowly things are getting back to normality - the only visible sign of something different from 2019 in the auditorium is the fact that about 80 percent of the 180 scientists sitting around me wear a mask.

The National Institute of Environmental Health Sciences may have science in its name, but they remain since the earliest part of the last decade a group funded by taxpayers that exists to scare taxpayers about science. 

Their in-house publication Environmental Health Perspectives has a new claim, and this one does not even involve questionnaires or cell studies hoping to "link" some chemical to some effect; it just picked a bunch of papers the authors liked and did a review of them to manufacture 'weight of evidence' about a term activists coined and NIEHS epidemiologists promote every chance they can - "forever chemicals."

Researchers at the Delft University of Technology (TU Delft) have realized the superconducting analogue to the semiconducting diode, the

Conservation in modern times is a misused term that trial lawyers often invoke to win lawsuits against companies before progress can commence but Brunei on the island of Borneo, which is about the size of the state of Delaware, has a great reason for all countries of the world to preserve it. 

The current landscape is similar to what was present during the Pliocene Epoch, 5.3 to 2.6 million years ago.
