Survey results show that workers believe the American workplace is physically and emotionally taxing, and they don't like the social environment. Since we are only now recovering from an economic malaise, they also worry about unstable work schedules. Some cited unpleasant and potentially hazardous working conditions.

Physicists from the ATLAS experiment at CERN have confirmed one of the oldest predictions of quantum electrodynamics (QED), finding the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of light – interact and change direction.

Nomophobia, defined as smartphone separation anxiety,  is when people perceive smartphones as part of their extended selves.

Counselors, lawyers and therapists are aggressively pushing it as the fad diagnosis of 2017, but what behaviors and descriptors can help identify people with high nomophobia ? A new paper compares how people considered to have high and low nomophobic tendencies perceive and value their smartphones.

No, this is a theoretically based rant about TSA. My students can get credit for reading it!

With all the tense situation about North Korea, I thought I should do a new post about the situation there. I'm doing this as part of my "Doomsday Debunked" articles I do to help people who are often very scared that the world will end in one way or another. First this is not a risk of global nuclear war. It’s nothing like the Cuban missile crisis. There we had two major powers facing each other on a hair-trigger. And each had the capability of destroying the other’s military capabilities.

Have you wondered why we can't see the Apollo landing sites from Earth? Moon is so far away that even the ISS at around 108 meters in length would span just over one pixel if Hubble were to photograph it on the Moon at its highest resolution. From NASA:

Can Hubble see the Apollo landing sites on the Moon?

No, Hubble cannot take photos of the Apollo landing sites.

“An object on the Moon 4 meters (4.37 yards) across, viewed from HST, would be about 0.002 arcsec in size. The highest resolution instrument currently on HST is the Advanced Camera for Surveys at 0.03 arcsec. So anything we left on the Moon cannot be resolved in any HST image. It would just appear as a dot.”

We know that corporations go where their market is. Whole Foods sets up shop in wealthy, progressive counties while smaller companies like Monsanto market to rural farmers. What about fast food companies? The claims have been that since there are obese people near places where high densities of restaurants exist, the restaurants must cause the obesity. Less considered is that people might move to where more food choices are and where those are dense, such as in cities, people tend to be more educated.

You may have seen this tank filling puzzle that's gone viral. But have you wondered what happens at a faster flow rate? Someone has tried it out, with a 3D printer. First though, let's look at the original puzzle. 

 Here it is.

Look closely, as it says.

Most people answer “G”.

If that's your answer too, take another close look. Many of the pipes are blocked, The line that blocks off D from C is not a mistake.

To find the real answer - well first, it looks like it's just a drip at a low flow rate from the drawing. So let's assume that..

From A to B to C is straightforward. None of them can fill before the next one.

I have recently been reproached, by colleagues who are members of the competing ATLAS experiment, of misusing the word "see" in this blog, in the context of searches for physics signals. That was because I reported that CMS recently produced a very nice result where we measure the rate of H->bb decays in events where the Higgs boson recoils against a energetic jet; that signal is not statistically significant, so they could argue that CMS did not "see" anything, as I wrote in the blog title. 

Cancer is a leading cause of illness and death worldwide. In 2015, the World Health Organisation (WHO) recorded 8.8 million cancer-related deaths and nearly twice that are diagnosed each year. Since people are living longer, cancer diagnoses is likely to continue to increase by about 70% for at least the next two decades.

Given that more cancers are likely in the developing world, the search is on for treatments  that are simple and inexpensive to manufacture. The answer may lie in herbal medicine. The problem, as always, is that while there are numerous anecdotes about those, there are few studies.
