Voyager 2: To Infinity And Beyond

Voyager 2: To Infinity And Beyond

A few years ago Voyager 1 entered the final frontier, that place where the solar wind becomes denser and hotter and pressure from gas between stars causes it to slow - the Termination Shock.
Now that Voyager 2 has reached its edge of the solar system, just under 7 billion miles from Earth, it has confirmed what astrophysicists had believed - the conflict between the solar wind and the interstellar wind has made that part of the solar system slightly squashed.

Finally, Women's Underwear Gets Its Own Study

Finally, Women's Underwear Gets Its Own Study

If you watch popular shows like “Undress the Nation” or Gok Wan’s “How to Look Good Naked” - what, you don't watch them? That's because that guy behind American Idol hasn't brought them here yet, and in these times of strife we need shows about women in underwear - but if you live in England and watch them you may have noticed something a researcher also noticed; when women wear the right underwear, they are more confident about their bodies and about their overall appearance which, to men, is the same thing. Who knew underwear was so important? Not me. All I know is there is 'dating' underwear - bras and panties match - and then 'dating a long time' underwear. You do the math.

Homeopathy: Putting your money where your science is ...

Homeopathy: Putting your money where your science is ...

A few hundred years ago, the Germans played a practical joke on the rest of the world; they invented a medical field based on the idea that you could cure a disease by using something that caused similar symptoms.It is called homeopathy and some people still haven't caught on to the joke. Why do I say joke? It's medicine that relies on the "energetic imprint" of substances to provoke the symptoms they already have - they're often so diluted that not even a molecule of the original substance remains - and the more diluted, the more powerful the cure, they say.

Sugary Drinks For Kids Exonerated In Study Of Child Obesity, Says Sugary Drink Organization

Sugary Drinks For Kids Exonerated In Study Of Child Obesity, Says Sugary Drink Organization

As a science site, one thing we understand is physics and how it can be exculpatory - no snowflake in an avalance ever has to take the blame.
The American Beverage Association(ABA) knows this too. They are the trade association representing the broad spectrum of companies that manufacture and distribute non-alcoholic beverages in the United States - that means soda and juice but also water and things that are basically good for you. Dr. Maureen Storey is their senior vice president for science policy and former director of the University of Maryland's Center for Food, Nutrition, and Agriculture Policy.
The ABA recognizes there is a lot of talk about childhood obesity and the link to sugary drinks. Since no snowflake in an avalanche takes the blame, that means obesity should be Doritos or it can be bread or it can be bad parents who buy their kids sugary drinks but the one thing that cannot definitively be linked to obesity are sugary drinks or the advertising departments at sugary drink companies. To prove this, Storey and colleagues did a meta-analysis (see notes) of 12 recent studies and published it in the June issue of the American Journal of Clinical Nutrition.

How The Bubonic Plague Made Europe Great

How The Bubonic Plague Made Europe Great

The bubonic plague, often called 'Black Death' after its most famous outbreak in the 14th century, still exists today and, like then, is caused by bacteria called Yersinia pestis that are found mainly in rodents and the fleas that feed on them. When other animals or humans contract this bacteria it is primarily from those infected rodent or flea bites.
Bubonic plague affects the lymph nodes resulting in swollen lymph glands (called buboes, thus the name bubonic), fever, chills and flu-like symptoms but in addition tiny broken blood vessels called petechiae can result in black spots on the skin and those black spots earned it the nickname that stuck when it reached England in 1348 AD.

Weekend Science: The Bar Pick-Up

Weekend Science: The Bar Pick-Up

Scientists like order and structure and methodology. Repeatability is even better, though that often requires additional grant funding. It's no different when it comes to weekends, bars and picking up science groupies.
But it's not so simple, even for scientists. The perfect world of methodology and repeatability is instead replaced by linguistic voodoo and trial and error regarding alcohol. Science, as always, is here to help.
There are rules, you see, but they are unwritten. By taking a broad cross-section of shared experiences we can establish a baseline and go from there. That is good science.

Carbon Capture And Storage: Hope Or Hype In The Global Warming Debate?

Carbon Capture And Storage: Hope Or Hype In The Global Warming Debate?

One consistent feature of human progress throughout history has been that science will come up with creative answers to current problems. When ancient people living in small tribes were running out of game to hunt, some leaders thought rationing and mitigation were the answers. They would have created a culture of despair. Domesticated livestock was the answer instead and then efficient agriculture and even terraforming.
Based on that confidence, a lot of people, me included, assume that global warming can be solved by some 'future technology' as yet undeveloped. Killing our economy by 25% now (yes, imagine it 25% worse) to stave off a .5 degree warming problem in 50 years is positively un-scientific.
But hope is not how things get done. People point to Y2K and say 'it was all hype, nothing happened' but they forget that's because we spent billions prior to that fixing problems. Likewise, acid rain was a huge concern in the 1980s and is not now because problems were addressed squarely.
Capturing and storing carbon dioxide is a solution the anti-global warming contingent (read, political pundits and bloggers using science to attack Democrats) say can keep us in an SUV Promised Land today. Then future technology can deal with it permanently.
To those people (in this case, Republicans) I say, 'Pretend a Democrat is saying Social Security will take care of itself in the future. Would you be skeptical?' Well, that's how I feel when they insist nothing needs to change and it will all be okay.

Revising Research Ethics In Developing Countries

Revising Research Ethics In Developing Countries

Biomedical research in developing countries is the kind of ethical condundrum we all think about.
On one hand, infectious diseases may cause up to half of all deaths in undeveloped nations(1), so no one needs advanced treatments more. On the other hand, these are human clinical trials of experimental drugs and socio-economic status does not make you a lab monkey in any sort of culture we want to call civilized.
So what is the solution? Americans are primarily distrustful of government, the bigger the worse, so a global body dictating clinical trials would be treated with a lot of skepticism but the perfect solution can't be moving ethical targets determined by various nations, funding sources or institutions as is done now.

Earth Day - Fabulous Fashionistas Save The Oceans Without Breaking A Sweat

Earth Day - Fabulous Fashionistas Save The Oceans Without Breaking A Sweat

Not that these women sweat anyway. "Horses Sweat, Men Perspire And Ladies Glow," my mother always told me.
But you get the idea. A group of fashion conscious women is making a difference this Earth Day - by looking fabulous!
Okay, as a man in his 40s with more children than I can count, I had a hard time even writing the word 'fabulous' without laughing.
But there is something serious happening. Chantecaille, a cosmetics company, has said it will donate five percent of the proceeds of its new “Protected Paradise” face and eyes compacts to the Pew Institute’s Pew Fellowship in Marine Conservation program, which provides a $150,000 award to each of five ocean experts around the world annually to develop solutions to critical ocean challenges.

Chocolate And Cholesterol - At Some Point It's Okay To Call B.S.

Chocolate And Cholesterol - At Some Point It's Okay To Call B.S.

John Erdman, a University of Illinois professor of food science and human nutrition who also chairs the Mars, Inc. Scientific Advisory Council and has received millions in funding from Mars, Inc., recognizes that taking money from a candy bar company (Mars Inc.) to do a study of their (Mars Inc.) candy bar proving it is healthy will have skeptics.
Not here. Hey, if Philip-Morris wants to highlight a study saying cigarettes cure cancer or Exxon-Mobil needs to promote a study saying automobile carbon monoxide improves asthma, we won't ridicule them just because of the funding. We'll ridicule them because of the methodology.
“Eating two CocoaVia dark chocolate bars a day not only lowered cholesterol, it had the unexpected effect of also lowering systolic blood pressure,” said Erdman on the results of a peer-reviewed study in The Journal of Nutrition.
Except the participants were also put on the American Heart Association’s “Eating Plan for Healthy Americans” (the Step 1 diet) two weeks before the study started.

Remember That '140 Liters Of Water In My Cup Of Coffee' Theory?  Here's Why Virtual Water Is Bogus

Remember That '140 Liters Of Water In My Cup Of Coffee' Theory? Here's Why Virtual Water Is Bogus

A few days ago the internet was abuzz with shocking headlines because the gentleman behind 'virtual water', professor John Anthony Allan of King’s College London, got an award from a water conservation group, the Stockholm International Water Institute (SIWI) for his work on advocating water conservation. Reading the news clippings about it, you'd have thought it was a Nobel prize for perpetual motion.
Perpetual motion is a good analogy. Generally, if you see something too ridiculous to be true, it's probably not true. A few weeks ago, for example, a VA Tech grad student got a prize for a 'gravity lamp' that was just the kind of alcohol-and-magic-fueled hocus-pocus that sets the internet on fire. It was green energy and cool tech all rolled into one. Except it didn't exist. Rather than being able to power a household bulb for hours, even an unsuitably-large one could only power a tiny 0.1-watt LED for 45 minutes. It's just physics.
So a few days ago people were aghast and outraged when they saw a number stating that 34 gallons of 'virtual water' went into a cup of coffee. I understand their panic. That means we only have about 9,588,235,294,117,647 cups of coffee left before all the water is gone.(1)
