While solar energy is clearly the future, it isn't ready yet. Two large obstacles are cost versus efficiency and storage.

Wind power is advocated by a much smaller group, because its obstacles are far greater. A new paper adds evidence to that, noting that when the operation and construction of storage batteries are included, solar power numbers can work but wind cannot.

Most electricity in the United States is generated at power plants that run on coal and natural gas – fossil fuels that contribute to global warming by emitting large amounts of carbon dioxide. Solar and wind power are emissions-free and renewable, but depend on sunlight or wind to operate, and require storage to take advantage of peak energy production times.

Music makes people nostalgic, it has long been said that music can bring us back to specific points in time.  Young adults surveyed recently are even fond of and have an emotional connection to the music that was popular for their parents' generation, says a new psychology paper. 

While songs that were popular in our early 20s seem to have the greatest lasting emotional impact, music that was popular during our parents' younger days- and likely what they played around kids - also evokes vivid memories. 

Low levels of pharmaceuticals and personal care products (PPCPs) were in crops irrigated with recycled sewage water, according to the first study conducted under realistic field conditions.  

When people think about the benefits of science to agriculture, they often think about American dematerialization. Farmers are producing far more food on far less land with far less ecological footprint than dreamed about 30 years ago.

Medicine of the 21st century is getting a hand from an idea Henry Ford had in the 19th century and implemented in 1908 - the concept of continuous mass production.

Billions of tablets, capsules and other forms of medicine that people take each year are still made made batch-wise.   A batch of ingredients typically undergoes a series of batch-wise reactions with isolation of solid intermediates before finally being isolated and drummed into bulk containers. The active pharmaceutical ingredient then moves on to the next step, processing into a granular form, followed by collecting into bulk containers. The processing continues through drying and other stages before being compressed into tablets and coated.

Kopi Luwak, coffee made from berries extracted the feces of Asian palm civet (Paradoxurus hermaphroditus), is all the rage. At our neighborhood Labor Day party we had not only that in attendance, but moonshine too (1), so you know it is trendy. We're thought leaders when it comes to drinks.

Research into the role of proteins called sirtuins in enhancing longevity has yielded contradictory results from many different scientists - while it's been fine for mouse studies, weaning human babies on a diet near starvation isn't possible. As a result, the benefits of a low-calorie diet are accepted by people who want to believe it.

While the Plantagenets are getting all of the attention in England these days due to the discovery of Richard III's remains (though the German Saxe-Coburg and Gotha family currently holding the monarchy also got a lot of attention thanks to a new baby), the Tudors are not done in Leicester.

Two Tudor tomb monuments originally intended to stand in Thetford Priory, Norfolk, are in an exhibition at the Ancient House Museum, Thetford, Norfolk, today until 29 March 2014.

Obese teenagers who lose weight are at greater risk of developing eating disorders such as anorexia nervosa and bulimia nervosa, a sign that there may be a psychology issue regarding their relationship to food.

But because weight loss is a healthy positive to both doctors and family members, eating disorders may not be adequately detected.  Up to 6 percent of American adolescents suffer from eating disorders, and in surveys more than 55 percent of high school females and 30 percent of males claim disordered eating symptoms including engaging in one or more maladaptive behaviors (fasting, diet pills, vomiting, laxatives, binge eating) to induce weight loss.

This is a simple build of a Michelson Interferometer using the SpyNet Laser Tripwire . About a year ago, I accidentally came across this toy and noticed that it has a red laser and two adjustable mirrors. It also has a receiver that will sound an alarm when the laser beam that shines on it is blocked. Yes, I have reverse engineered the receiver—a rather simple circuit, really—and, of course, improved it and may post an article about it to demonstrate an SCR (Silicon-Controlled Rectifier). I requested a reviewer’s sample from Jakks Pacific but did not receive one, so I had to wait for an after Christmas sale and found a set for 80% off (about $5.00 USD which was less than purchasing a laser pointer and two makeup mirrors).
