Meditation Gurus In Academia Should Stop Claiming Social Rejection Causes Violence And Meditation Prevents It

Science 2.0 - Jun 17 2018 - 08:06

Meditation advocates from three schools say a lower ability to cope with the pain of being rejected by others leads to violence, but that people greater levels of mindfulness, a psychological fad where practitioners maintain attention on and awareness of the present moment -- are better able to cope with such pain.

On The Residual Brightness Of Eclipsed Jovian Moons

Science 2.0 - Jun 16 2018 - 12:06
While preparing for another evening of observation of Jupiter's atmosphere with my faithful 16" dobsonian scope, I found out that the satellite Io will disappear behind the Jovian shadow tonight. This is a quite common phenomenon and not a very spectacular one, but still quite interesting to look forward to during a visual observation - the moon takes some time to fully disappear, so it is fun to follow the event.
This however got me thinking. A fully eclipsed jovian moon should still be able to reflect back some light picked up from the still lit other satellites - so it should not, after all, appear completely dark. Can a calculation be made of the effect ? Of course - and it's not that difficult.

California Judge Denies Trial Lawyer Efforts To Get A Glyphosate Warning Label

Science 2.0 - Jun 15 2018 - 16:06

A federal judge's recent discussion about why glyphosate should not have a warning label in California, despite the efforts of trial lawyers and the environmental groups they pay, not only shows the label would have no scientific validity, it calls into doubt Proposition 65 itself.<

Science Of Literacy: Reading To Children Doesn't Teach Them How To Read

Science 2.0 - Jun 15 2018 - 16:06
A team of psychologists hope to win a battle in the "reading wars," emphasizing the importance of teaching phonics in establishing fundamental reading skills in early childhood. 

By synthesizing findings from more than 300 research studies, book chapters, and academic journal articles published across a variety of scientific fields, they hope to create an evidence-based account of how children learn to read

Sexual Harassment In Academia

Science 2.0 - Jun 15 2018 - 11:06
A few years ago a cultural anthropologist levied a bombastic charge against her own field; using uncontrolled anonymous surveys with undefined terms she claimed almost every woman doing field work had been subjected to sexual harassment or even rape. It got a lot of attention but it lacked serious methodology, even for surveys.

When Is It Sexual Harassment? When It's Written By A Man

Science 2.0 - Jun 15 2018 - 09:06
An experimental study which sought to determine perceptions of sexual text (sext) messaging situations concluded that men and women were judged differently by the sext messages they sent, even when they were the same.

When messages were unsolicited, men were judged as creepy while women were judged as more appropriate.

The strange conclusion by the authors from their finding was not the obvious one, that men were being discriminated against, "slut shaming" for guys, but that consent is important in sexting. 


Sexting. Vaguely date rapey when a guy does it. But when a woman does it, hegemonic masculinity stereotypes gave more women a free pass.

What Has The Kim Trump Summit Achieved?

Science 2.0 - Jun 14 2018 - 12:06

Trump has had a lot of criticism after the summit, with many saying he conceded too much to Kim. I don’t think he did at all myself. All he gave him was a meeting with him, and a couple of days of his time. And he built trust. He thinks that’s important. Previous presidents didn’t think it was important, they proceeded on a basis of distrust. He is trying something new.

You Are Probably A Better Dad Than Your Father Was

Science 2.0 - Jun 14 2018 - 11:06
In the war for attention, a lot of parents are made to feel like they are not very good if they don't get their child into the right pre-school, buy the right food which lacks the additives it's fashionable to exclude, or spent Quality Time shuffling them from sporting events to music classes to book readings.

You can relax. You may not be perfect, but you are still probably a better dad than your dad was, finds an analysis of survey results published in the Journal of Marriage and Family.

American Toddlers Eat Too Much Sugar - So Does Everyone Else

If you added Vitamin C to Pepsi, you know what you would have? Orange juice. 

There is nothing wrong with orange juice (public relations manufactured health halo aside), just like there is nothing wrong with Pepsi, they should both be treats. Unfortunately, for the U.S., the richest country in the world, no food need ever be a treat, they can all be purchased every day. And that is bad for kids.

Trepanation: Sometimes You Needed A Hole In The Head - And Incans Were Really Good At It

Science 2.0 - Jun 10 2018 - 13:06
For thousands of years, trepanation--the act of scraping, cutting, or drilling an opening into the cranium--was practiced around the world, primarily to treat head trauma but also for headaches, seizures and mental illnesses. Sometimes it was even done to expel demons.

It sounds garish now, but ancient Peruvians were surprisingly adept at it, so adept that Incan "neurosurgeons" had twice the survival rate for the procedure than better equipped surgeons during the American Civil War centuries later.

Obviously there could be differences in when it was done, so it may be due to confounders that in Incan times the mortality rate was between 17 and 25 percent while during the Civil War it was between 46 and 56 percent.

Modeling Issues Or New Physics ? Surprises From Top Quark Kinematics Study

Science 2.0 - Jun 10 2018 - 07:06
Simulation, noun:
1. Imitation or enactment
2. The act or process of pretending; feigning.
3. An assumption or imitation of a particular appearance or form; counterfeit; sham.

Well, high-energy physics is all about simulations. 

We have a theoretical model that predicts the outcome of the very energetic particle collisions we create in the core of our giant detectors, but we only have approximate descriptions of the inputs to the theoretical model, so we need simulations.

Anthony Bourdain Has Committed Suicide And CDC Says Media Should Be Careful About Reporting It

Science 2.0 - Jun 08 2018 - 11:06
Suicides have gone up in the United States since 1999, according to the CDC, but then state it is more than a mental health issue.

There is no rhyme or reason to the increases, half of states, from cultures as different as Vermont and North Dakota, saw large changes of over 30 percent.  Suicide is the 10th-leading cause of death in the U.S., and rates have been climbing steadily for years. With 44,965 suicide deaths in 2016, half of them using a firearm, the CDC would like to know why.

Canadian Journal Advocates For Hepatitis C Screening Of All People Born 1945-1975

Science 2.0 - Jun 08 2018 - 11:06
One way to manage chronic hepatitis C virus (HCV) is to abandon existing guidelines and screen all people born between 1945 and 1975 for the disease, according to a new paper

Chronic HCV is a major public health problem in Canada with serious health effects leading to premature death. In 2013, about 252,000 Canadians were infected with HCV. People born between 1945 and 1975 have the highest rates of HCV, although an estimated 70% of this group have not been tested.

Debunked: World To End In One Of Three Horrible Scenarios In Mathematical Model By Adam Frank

Science 2.0 - Jun 04 2018 - 06:06

Short summary: This is a first paper in what they hope to be a long term study. It’s an interesting project, but it should not be used to predict what will happen to Earth in the future. Their research is at far too early a stage to do that. It makes many simplifying assumptions that do not apply to Earth as it is now. I am publishing this article because I've been contacted by several people who got scared by the news reports about this study thinking it means we are likely to go extinct. No, it does not mean that at all.

MiniBoone Confirms Neutrino Anomaly

Science 2.0 - Jun 01 2018 - 08:06
Neutrinos, the most mysterious and fascinating of all elementary particles, continue to puzzle physicists. 20 years after the experimental verification of a long-debated effect whereby the three neutrino species can "oscillate", changing their nature by turning one into the other as they propagate in vacuum and in matter, the jury is still out to decide what really is the matter with them. And a new result by the MiniBoone collaboration is stirring waters once more.

Trump Kim Summit: Expect Hollywood Filming! Grand Gestures! Real Progress! Civilian Space Program Uniting North & South Korea?

Science 2.0 - May 30 2018 - 22:05

First, one thing we will get for sure is a Hollywood style production of the visit with good music too. Korean television has been devoted for many years to constant Hollywood style movies about Kim Jong Un, and they have got very good at it, high production values. Trump can expect Kim to do the meeting proud if their film makers are given a free hand as they have been for the meetings with Moon and with Pompeo. It’s not surprising, the North Koreans have been doing this for all of Kim Jong Un’s activities for years now - he goes to talk to workers in a factory in NK and it becomes a Hollywood type experience for the viewers.
