Want to scare people about a pesticide? Compare it to DDT. 40+ years after it was banned in a bit of scientization of politics, people have still heard of it. DDT may be the only pesticide many people have ever heard of. Environmental groups love to invoke it for that reason.

But if you are a fan of science, when you see a DDT comparison, you know evidence has left the building. DDT, when misapplied, was bad, just like every other compound, including water, can be bad. There was nothing exceptional about it other than the fact that it could have saved millions of kids from malaria if activists were forced to do studies before issuing press releases. But once you get a Joni Mitchell song written about your product, someone in Congress is going to take action.

When you are young, you shape your possibilities. Research in psychology and neuroscience shows us that your personality and your intelligence develop during childhood and teenage years until becoming fully developed by age 25. Likewise, during your younger years, you write the story you tell about yourself – who are you, how do you understand your worth and your potential? Then you live this story through your adult life. In other words, the person you shape while growing up can be the person you’re stuck with. So allowing drugs or alcohol to influence this young person can affect not just who you are today, but who you can be and will become. Here are five reasons why substance abuse is especially dangerous for young people.

Did you know that when you drink water, you are not really being vegetarian?

I didn't either. It turns out that when you drink water, it could have microbes and other small stuff - well, I knew that part. What I did not know is that viruses and bacteria and such were considered animals to vegetarians. So even if you purify water by boiling it and killing the germs, you are still drinking dead animals.

What to do for truly ethical water drinkers? Now you have the solution, the Prestige Lifestraw.
It's no secret that politicians have always favored corporations that are involved in their pet causes - and it's no secret that wind turbines are killing endangered birds and forcing a giant migration of more.

What is less well known is that if you are a wind energy corporation, not only have you been stuffed with government subsidies for the last five years, you are not going to be prosecuted no how many eagles you kill. Unless you are also a fossil fuel company, like Duke Energy, they got prosecuted. Otherwise, you pay a token fine and that is that.
After great pains to simulate the foreground dust the Cosmic Microwave Background, gravitational wave result of BICEP2's B-Mode observations is still in question.  The simple fact is we do not really know what the foreground dust contamination really is right now.   The PLANCK collaboration will release that data, and sometime this year, their own map of CMB B Modes.   PLANCK's release of a real foreground dust map, not one based on a presentation slide, which is what the BICEP2 team first used, will settle this once and for all.    All of that said, the work of the BICEP2 team is good and worthy science, weather they are shown to be right, wrong, or only partially right  (i.e. if there is an effect but not as big as they claim).   
Have you ever wondered how hand warmers and cold packs worked? The kind that can be stored at room temperature and then used when needed depend on exothermic and endothermic chemical reactions. An exothermic chemical reaction gives off heat into its surroundings. Conversely, an endothermic reaction absorbs heat from the surrounding environment.

"Hell, if I could explain it to the average person, it wouldn't have been worth the Nobel prize. "

R. Feynman, People magazine, 1985

I sure cannot disagree more with Dick than on the above sentence !
Dr. Karl Kruszelnicki has described a very interesting case of a cancer patient named Daniel. Daniel was a fit man in his mid 30's and was diagnosed with malignant melanoma. Within two months it had spread to his lymph nodes and within one year had sprouted secondary cancers in his lungs and liver. During this time Daniel could no longer play basketball and lost over 30 pounds. The cancer then spread to his right hip causing severe pain. The consulting doctor decided to treat the hip pain (tumor) with a high dose of radiation hoping that the damage to the tumor would provide pain relief. The doctor then booked a 3-month follow up appointment not really expecting Daniel to be alive. Three months later, Daniel not only showed up but had gained 11 pounds and was pain free.
A genetically modified banana, boosted to have higher levels of alpha and beta carotene, which the body converts to vitamin A, has the best backer imaginable - The Bill And Melinda Gates Foundation.

It also has a big obstacle: it is really easy to scare people who don't understand the promise of biology, and fear and doubt are the specialties of anti-science groups who have consistently sought to undermine progress in food. But this is needed. The East African cooking banana is a staple with low levels of pro-vitamin A and iron. An improved version means not having to change farmers or culture. Like its vitamin-enriched counterpart, Golden Rice, the banana is a slightly different color. But it's what can't be seen that has the real value. 

Summer is the season we honor our veterans. There’s Memorial Day and the 4th of July, but even beyond these holidays, a summer filled with barbecues and Slip n’ Slides is a time to appreciate the life our country offers and remember the veterans who make it possible. This summer as we are remembering our veterans’ contributions, we are forced to confront our own failures. See, there’s an implicit deal we make as a society with these people who fight for our freedom – you risk your lives so that we don’t have to, and in return we as a society will take care of you. With scandals at V.A. hospitals, we’ve reneged on our end of the deal.
