Device cools itself in the blazing-hot Sun

Stephan:  Cooling eats up 15 per cent of the energy used by humans. A huge factor in making the transition out of the carbon era. As this report explains a new technology may change that game fundamentally. This is potentially very good news.

Window of opportunity: Shanhui Fan and colleagues

When the weather gets hot, everyone wants to stay cool. That often means turning on the air conditioning, which consumes vast amounts of energy – and money – in developed countries. But that could change, thanks to a new photonic device that can cool to below the ambient temperature while consuming no energy.

Cooling accounts for around 15% of the energy used in buildings in the US and contributes heavily to greenhouse-gas emissions. Worldwide, energy consumption related to cooling is expected to surpass that used for heating by 2070.

Open window

Objects can cool themselves without consuming energy by radiating energy in the form of infrared light. This process is not normally very efficient because objects can also be warmed by convective air currents and by absorbing radiation emitted by other objects and by the air. However, air absorbs and emits very little infrared radiation at wavelengths of around 8–13 μm. It is through this “window” that the Earth lowers its temperature at night – especially when the sky is clear – by sending […]

Half a million new cancer cases each year linked to BMI

Stephan:  It is becoming increasingly clear that obesity is killing Americans at an unprecedented rate. If you are morbidly obese please do yourself, your family, and your friends a favor and this Thanksgiving make the commitment to change your eating habits so that you are around and in good health longer.
The new analysis finds that 3.6% of the total global cancer burden is linked with high BMI.

The new analysis finds that 3.6% of the total global cancer burden is linked with high BMI.

Nearly half a million new cancer cases per year can be attributed to high body mass index, according to a new analysis conducted by researchers from the International Agency for Research on Cancer and published in The Lancet Oncology. (emphasis added)

High body mass index (BMI) is known to be a risk factor for cancers affecting the esophagus, colon, rectum, kidneys, pancreas, gallbladder, breasts, ovaries and endometrium.

The new analysis – which looked at data from 2012 – finds that 3.6% of the total global cancer burden is linked with high BMI, and that cancer due to overweight and obesity is far more common in developed countries than in less developed countries.

“Overall, we see that while the number of cancer cases associated with overweight and obesity […]

How Our Brains Transform Remote Threats Into Crippling Anxiety

Stephan:  Fear, reality based or manufactured, has become a major factor in the lives of most Americans. One of the reasons I consider Fox News and the Theocratic Rightist media establishment treasonous is that their principal activity is creating doubt and fear through disinformation. This is done deliberately and with purpose. The point of the exercise is not to education or to create public debate but to foster hate and anxiety, and I don't see this as being much different from slowly poisoning people.

U.S. EPA: We need tougher ozone standards

Stephan:  This is some excellent news. This makes my day, and will strongly effect our future.

For 44 years, the U.S. Environmental Protection Agency (EPA) has defended the American people’s right to breathe clean air by setting national air quality standards for common air pollutants.

Successful public health protection depends on the latest science. Think of it this way: If your doctor wasn’t using the latest medical science, you’d be worried you weren’t getting the best care.

That’s why the Clean Air Act requires EPA to update air quality standards every five years, to ensure standards “protect public health with an adequate margin of safety” based on the latest scientific evidence.

So today, following science and the law, I am proposing to update national ozone pollution standards to clean up our air, improve […]

Regulation Is Squeezing Out Potrepreneurs, Clearing the Road For Big Cannabis

Stephan:  This is what I feared would happen. A few large players would through influencing the government come to control marijuana. Marijuana should be thought of like wine, a product growing from a living plant, not a pharmaceutical model. This is not a happy trend.

A 46-year-old mother of three, Dooley is the cofounder and president of Julie’s Baked Goods, a purveyor of cannabis-infused snacks. She has celiac disease and wanted to create gluten-free products that would relieve her pain without damaging her intestine. Dooley’s Denver company released its first product, granola mixed with cranberries and almonds, in 2010 and now sells about 6,000 units a month, employing 11 people.

Even in Colorado, where medical and recreational marijuana are both legal, the cannabis business involves its share of hassles. Initially, Dooley’s license cost $1,250 and required a 25-page application. Renewing it, she said, cost more than twice that and required investing about $25,000 in the company’s kitchen, including a security system with 24-hour video surveillance. She wouldn’t have a business today if her husband weren’t a manufacturing specialist, she says.

As hard as she’s worked, Dooley’s experience has been relatively easy for a medical marijuana business in this country. Marijuana remains illegal federally, which leaves every state which allows the product to figure out its own regulations. […]
