Even small tumors can be aggressive, according to a study in patients with early stage breast cancer presented at the ESMO 2017 Congress in Madrid. They found that nearly one in four small tumors were aggressive and patients benefited from chemotherapy. Aggressive tumors could be identified by a 70-gene signature.
A while back I wrote my article "Can Giant Airships Slowly Accelerate to Orbit Over Several Days" . It lead to a lot of discussion and as usual whenever you discuss John Powell's ideas, there were physicists and aeroengineers saying it is impossible, and others saying it can be done. So anyway as part of this I had an especially interesting online discussion over many days with James Fincannon on the Space Show blog and much of this article comes out of that discussion. Unlike many of those who get involved in these discussions on the topic, he actually did many detailed calculations and shared them on the blog.-->
Why The IAU Definition Of Planet Has A "Use By Date" - And How We Can Get To Call Our Moon A Planet!
Yes. I think all the objects large enough to reach equilibrium under gravity should be called planets. That would include Ceres too, and our Moon as a “moon planet”, and dwarf planets like Haumea, and Eris. This is the definition many planetary scientists use already - they call it the "geophysical definition".
This is not for nostalgic reasons. It's because it's a natural distinction to make. Something large enough to be rounded under gravity is normally going to have geological features too, differentiated interior and a large surface area. The smallest ones, perhaps around 200 kilometers in diameter, still have a surface area similar to that of England, or Arizona.-->
A pervasive myth in Australia is that hot weather is the greatest danger to our health. In reality, it’s more likely cold weather will kill you.
For all our concern about the dangers of heatwaves, simple analysis of mortality data suggests the cold months present a much greater health risk. Almost 7% of deaths in Australia from 1988 to 2009 were attributable to cold weather. Less than 1% of deaths were attributable to heat.-->
Pesticides get different treatment though.
Take the class of insecticides so much in the news, neonicotinoids, that some have blamed for problems with bee health. Didn’t the European Union ban them claiming they were posing unacceptable risks to bees? Isn’t that case closed?
This is an article by the space engineer and Mars colonization enthusiast Robert Zubrin, The Planetary Protection Racket claiming that we don’t need to protect Earth from Mars microbes or Mars from Earth microbes. This is not he first time he has said controversial things like this, and they are not taken seriously by the planetary protection experts. To give you an idea of how his arguments are received by them, let’s go back to what I think is the first time he put forward forceful arguments in print saying that there is no need to protect Earth from Mars microbes.-->
If I am alive, I probably owe it to my current very good physical shape.
That does not mean I narrowly escaped a certain death; rather, it means that if I had been slower there are good chances I would have got hit by lightning, under arduous conditions, at 4300 meters of altitude.-->
The heads of more than 100 of the world’s top artificial intelligence companies are very alarmed about the development of “killer robots”. In an open letter to the UN, these business leaders – including Tesla’s Elon Musk and the founders of Google’s DeepMind AI firm – warned that autonomous weapon technology could be misused by terrorists and despots or hacked to perform in undesirable ways.-->
The dominant Australian community would very much like to keep Indigenous communities from alcohol, but indigenous communities aren't having it. A giant black market has sprung up and such non-government alcohol sells for up to 1100 percent of the retail price.-->
The Centers for Disease Control and Prevention seem more scared than elated by United States smoking rates. They have migrated from a war on the world's top killer, smoking, to being in a war on a chemical, nicotine.
They needn't be concerned. Science and health have won, and it wasn't because of taxes on cigarettes or a cottage industry of anti-smoking ads built by a tobacco company settlement, it was because of peer pressure. In young people. As the American Council on Science and Health, a pro-science consumer advocacy group based in New York City, has said since the 1970s, smoking is a pediatric disease. In the past, 90 percent of smokers picked up the habit by age 18, making adolescence a critical time for smoking-prevention efforts.
Center for Science in the Public Interest, a litigation group that sues food companies, may be dusting off some of its old materials after new report which finds "good" cholesterol, also known as HDL, might not be as good as we think.
The new paper contradicts findings from the last 25 years that high levels of HDL in the blood are a good thing. They instead found that people with extremely high levels of good cholesterol have a higher mortality rate than people with normal levels. For men with extremely high levels, the mortality rate was 106 percent higher than for the normal group.
Researchers looked at frequency magnetic resonance imaging (fMRI) images to compare neural responses to food cues in overweight and normal weight adolescents.
They noted that food stimuli activated regions of the brain associated with reward and emotion in all groups but overweight adolescents had progressively less neural activity in circuits of the brain that support self-regulation and attention.
If mouse studies were transferable to humans, we'd have cured every disease thousands of times. That is the big reason why you shouldn't accept scaremongering about the chemical of the week in the New York Times, or claims about Miracle Vegetables in the Washington Post.
Will The August Eclipse Show Nibiru? No - But You Get To See Four Bright Planets, Including Mercury - Normally Hard To Spot :)
I’m getting messages from scared people today. The fearmongers and charlatans are saying that a giant planet Nibiru is going to appear during this solar eclipse and is due to hit Earth or do a devastating very close flyby 33 days later on September 23. No! This is total BS and nonsense promulgated by people who couldn’t predict the date of a solar eclipse or where to watch it if their life depended on it.
To everyone who is still scared today - nothing is going to happen I assure you. It's just a shadow. You are getting scared of a small shadow 70 miles wide passing briefly over the surface of Earth. Meanwhile you experience an average of twelve hours of darkness every single night.-->
Licorice roots have a diverse history, having been used throughout history as a flavoring agent and as an ingredient in some licorice candies, while in ancient Egyptian times it was a tea and the Chinese used it for medicinal purposes.
One trend in the alternative medicine movement, which seeks to replace approved pharmacology with essentially untested natural products (as long as they carry a disclaimer FDA has not verified their efficacy or safety), is for women to take licorice extracts as supplements to treat hot flashes and other menopausal symptoms.
On August 21st, from west coast to east the United States will be treated to a rare event; an eclipse of the sun. Not just a partial eclipse either. Through the entire arc, a swath of land about 70 miles wide will have a total eclipse. There's been so much excitement that social media has made "path of totality" part of the lexicon.
