Cancer Dormancy: Why Cancer Cells Go To Sleep

Apr 27 2018 - 09:04

Cancer has always been thought of as something that grows rapidly and uncontrollably, but this view may be wrong.
New evidence suggests that cancer alternatively uses the “accelerator” and the “brake” in order to survive.

2040 Is Likely Earliest Date For Mars Sample Return (unless Sterilized) And Little More Than Astrobiology Technology Demo

Apr 26 2018 - 17:04

The BBC has just reported that ESA have signed a letter of intent to co-operate with NASA on a Mars sample return (see Agencies aim to bring back rocks from Mars). I hope this does not mean a change of focus for ESA from in situ searches to a sample return. It would be so sad if it did mean that. The NASA program is more of an astrobiology technology demo than an actual astrobiological mission. They would return our very controversial Tissint and ALH84001 meteorites as top priority targets for the organics and in the case of Tissint the carbon isotope ratios - and would not be able to detect life amongst all the meteorite organics.

With The Science Settled That Neonicotinoids Don't Cause Honeybee Problems, Why Does Europe Need To Ban Them?

Apr 26 2018 - 15:04
Everyone agrees the health of bees is a concern but there is confusion about why different governments have reacted. Scientific experts note any acute problems are due to a combination of bee keeping practices, Varroa destructor mites (which vector roughly a dozen different diseases into beehives) and the widely prevalent gut fungus Nosema ceranae. Environmental activists, on the other side, insist bees are dying and it's due to neonicotinoid pesticides.

Why Polar Regions Of Mars Are Of Outstanding Interest For Astrobiology - And Why We Haven't Been Able To Explore Them Yet

Apr 26 2018 - 10:04

The reason we know so little about the polar regions is not lack of interest. The polar regions are of great interest, for instance the Martian dry ice geysers in Richardson crater, one of the most interesting dynamic processes on Mars and the polar regions also have astrobiological interest too. There are potential habitats there that might even have fresh liquid water within 7 cms of the surface of clear ice - of all the unexpected things to find on Mars with its near vacuum atmosphere!

Correct Blitz Chess - A Nice Miniature

Apr 26 2018 - 08:04
Playing chess games flawlessly is a super-human endeavour, which even machines are still having a hard time achieving. However, the occasional flawless game does arise in human practice, albeit rarely. Usually it is a grandmaster who pulls it off. The absence of sub-optimal moves can be ascertained by extensive computer analysis these days, so the quality of the moves is not in question.

Improve Mitochondria And You May Improve Heart Health

Apr 25 2018 - 12:04
A small study published in Hypertension resurrects the notion that oral antioxidants, broadly dismissed as ineffective, could reap measurable health benefits if they are bioavailable. And it was in older people.

The study consisted of 20 healthy men and women age 60 to 79 from the Boulder area. Half took a placebo and half took 20 milligrams per day of a commercially available supplement called MitoQ, which is Coenzyme Q10 which uses chemistry to allow the antioxidant to penetrate the membrane of mitochondria, the energy factories of our cells.

Violent People With Less Access To Guns Would Be A Homicide Deterrent

Apr 24 2018 - 14:04
While criminals will get guns illegally, and people who use guns to commit suicide may not be deterred by anything, people who are already prone to violence would be deterred from homicide by gun law changes, according to a new article which argues that federal and state laws should include people who abuse their partners regardless of whether they are married to them or not. And findings of abuse should be grounds for not being allowed access to guns.

Mental Fatigue May Be A Key Issue In Seniors' Walking Ability

Apr 24 2018 - 14:04
Today at the American Physiological Society (APS) annual meeting at Experimental Biology 2018 in San Diego a group of scholars posited that low "mental energy" may affect walking patterns in older adults more than physical fatigue.

Youtube Doomsday Channels May Earn Over $1 Million A Year - Young Teens Suicidal - Petition: Stop Supporting With Ad Revenue

Apr 23 2018 - 19:04

Steve Olsen just revealed to Metro magazine that he earns $50K a year from his doomsday YouTube channel WSO. Based on this then we can begin to estimate the total earnings from all the high earners and it may well be over $1 million a year.

Here is the reasoning.

Social Blade has the upper estimate as $20.7K for his channel. I hadn't had any way until today to judge if their estimates are right or not. It now seems that at least in this one case, it's an under estimate.

The T-Index: More Meaningful Metrics For Scientists

Apr 23 2018 - 17:04
Academics direly need objective, meaningful metrics to judge the impact their publications have on their field of expertise. Nowadays any regular Joe will be able to show many authored papers in their CV, and it will be impossible to objectively assess the relative merits of each and every one of them, if you are trying to rank Joe in a list of candidates for tenure, or just a research job at a University.

Neonics: Environmental Groups Get 219,000 On A Petition Against EPA Science

Apr 21 2018 - 09:04
A week after the Science March, environmental groups have turned up the heat on politicians, hoping to use the famous DDT strategy (ignore scientists, get a politician to do the work) to get a ban on a class of pesticides called neonicotinoids (neonics), which are sprayed on seeds so that there is less environmental strain and food waste.

People Who Smile Are Regarded As Cooler

Apr 20 2018 - 11:04
Imagine one person walks into a room and they are smiling and saying hello to everyone. Then imagine another person who walks in quietly, looks grim, and heads to a corner.

Rapper Kanye West once told the press he doesn't smile for photos because "it just wouldn't look as cool," and humanities scholars who have to write about something have written that the reason Dean became cool was because he didn't smile. But is it true?

Food Waste Is Why Vegetarians Are Harder On The Planet Than Meat Eaters

Apr 19 2018 - 17:04
A new study finds that Americans waste nearly a pound of food per person per day. And at the top of it is fruits and vegetables. Way below those is dairy, and meat waste is almost a third of what fruits and vegetables are.

People who believe they "eat more healthy" than others - the organic elite and vegetarians - have a food fetish for fresh vegetables. And Americans are told by government committees and pyramids they should want to eat vegetables, so they buy them and then throw them out when they start to spoil. When is the last time you threw out moldy pizza?

Asperger Killed Disabled Kids For The Nazis

Apr 19 2018 - 17:04
All of the intellectual elites who joke they have Asperger's or are "on the spectrum" as an excuse for behavior they know is simply annoying or weird are now going to bring that to a full stop. It's going to be a lot cooler to just admit they are annoying or weird.

The reason is because a new analysis in Moleular Autism finds that Hans Asperger, the Austrian pediatrician for whom a mild segment of the autism spectrum is named, collaborated with Nazis and helped kill disabled children.

If Your Doctor Talks About Homeopathy, You Have A Terrible Doctor

Apr 19 2018 - 16:04
Homeopathy, a belief from 200 years ago that if you took something that mimicked the symptoms of a disease you could prevent a disease, or that extremely diluted water with a molecule of something will be curative, has never been shown to work in any clinical trial.

Nonetheless, some people swear by it, much as people believe other placebos. What to do if your doctor recommends it? In the United States, a doctor is ethically forbidden from prescribing a placebo outside a clinical trial, but it is known some do. And lots of folk medicine/alternative medicine/integrative medicine people will claim it works if you believe it works.

The Wisdom Of Crowds - Now With Even More Wisdom

Apr 19 2018 - 16:04

In 1907,Francis Galton recorded the entries from a competition where people guessed the weight of an ox. After analyzing hundreds of estimates the statistician found that while individual guesses varied wildly, the median of the entries was surprisingly accurate, within one percent of the ox's real weight.

Galton published the results and his theory of collective intelligence, the "wisdom of crowds," became part of the lexicon.

Medical Marijuana Won't Help Fight The Opioid Epidemic - It May Enable It

Apr 19 2018 - 16:04

Advocates are claiming medical marijuana can help to fight the opioid epidemic but data show the opposite. Rather than being at lower risk, people who use medical marijuana may be at higher risk for non-medical prescription drug use.
Much of medical marijuana usage was always recreational and a new study in the Journal of Addiction Medicine finds that people who use medical marijuana have higher rates of prescription drug use - including pain relievers.

Does Use of Medical Marijuana Increase or Decrease Prescription Drug Use?

So Now You Are Celebrating Surviving The End Of The World - But Expect After Effects For A Few Weeks

Apr 19 2018 - 02:04

For the last three weeks we've had constant PM's and comments on Doomsday Debunked as a result of a viral hoax that pranked probably hundreds of thousands of people worldwide. Perhaps you are one of them, and got scared of an alien invasion?

It’s on the basis of some tweets by anonymous people that sketched a bizarre story that for some reason got many hooked, partly because it made no sense and they kept puzzling over this bizarre stupid story, even knowing it was silly, still they couldn’t help but nag away at it and getting more and more scared because it didin’t make sense.

Lahontan Cutthroat Trout Species Never Knew It Was Extinct

Apr 18 2018 - 15:04
Though we read a lot of claims about impending extinction, the biological reality is that we don't know anything about 99.9999999 percent of species that have ever lived. And then there are species only newly discovered that are immediately declared endangered because an academic only recently named them in a print journal.
