America's epidemic of unnecessary care

America's epidemic of unnecessary care | Semiotic Adventures with Genetic Algorithms | Scoop.it

Millions of people get tests, drugs, and operations that won’t make them better, may cause harm, and cost billions.


Via Luca Baptista
Semiotic Sorceress's insight:

"Virtually every family in the country, the research indicates, has been subject to overtesting and overtreatment in one form or another. The costs appear to take thousands of dollars out of the paychecks of every household each year. Researchers have come to refer to financial as well as physical “toxicities” of inappropriate care—including reduced spending on food, clothing, education, and shelter. Millions of people are receiving drugs that aren’t helping them, operations that aren’t going to make them better, and scans and tests that do nothing beneficial for them, and often cause harm."

Solar power with a view: Transparent luminescent solar concentrators

Solar power with a view: Transparent luminescent solar concentrators | Semiotic Adventures with Genetic Algorithms | Scoop.it

Researchers have developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a flat, clear surface.

 

Research in the production of energy from solar cells placed around luminescent plastic-like materials is not new. These past efforts, however, have yielded poor results -- the energy production was inefficient and the materials were highly colored.

 

"No one wants to sit behind colored glass," said Lunt, an assistant professor of chemical engineering and materials science. "It makes for a very colorful environment, like working in a disco. We take an approach where we actually make the luminescent active layer itself transparent."

 

The solar harvesting system uses small organic molecules developed by Lunt and his team to absorb specific nonvisible wavelengths of sunlight. "We can tune these materials to pick up just the ultraviolet and the near infrared wavelengths that then 'glow' at another wavelength in the infrared," he said.


The "glowing" infrared light is guided to the edge of the plastic where it is converted to electricity by thin strips of photovoltaic solar cells. "Because the materials do not absorb or emit light in the visible spectrum, they look exceptionally transparent to the human eye," Lunt said.

Mystery of Bizarre Duck-Like Ocean Sound Solved

Mystery of Bizarre Duck-Like Ocean Sound Solved | Semiotic Adventures with Genetic Algorithms | Scoop.it
A mysterious duck-like sound recorded in the ocean around Antarctica has baffled scientists for decades, but the source of the sound has finally been found, researchers say. "In the beginning, no one really knew what it was," said Denise Risch, a marine biologist at NOAA Northeast Fisheries Science Center in Woods Hole, Mass. Because the sound was so repetitive, scientists first thought it might be human-made, possibly coming from submarines. The noises also occur seasonally, and have been heard simultaneously in the Eastern Weddell Sea off Antarctica and Western Australia. In February 2013, during the Southern Hemisphere's summer, Risch's colleagues tagged two Antarctic minke whales (Balaenoptera bonaerensis) off of Western Antarctica with suction-cup tags.

Brilliant WarkaWater Towers Collect Drinking Water from Thin Air in Ethiopia

Brilliant WarkaWater Towers Collect Drinking Water from Thin Air in Ethiopia | Semiotic Adventures with Genetic Algorithms | Scoop.it
Italian designer Arturo Vittori has unveiled the WarkaWater Tower, a revoluntionary new way to collect clean drinking water in Ethiopia and other parts of Africa. The artist was inspired by a recent trip to a remote village in northeastern Ethiopia where water collection is often a dangerous and incredibly time-consuming process. With just a little financial backing, Vittori hopes the innovative WarkaWater Towers, which take advantage of condensation, will provide a more reliable, efficient and sustainable method of water harvestingfor local women and their families.

New York is the world's most wasteful megacity, in 3 charts

New York is the world's most wasteful megacity, in 3 charts | Semiotic Adventures with Genetic Algorithms | Scoop.it

The city consumes more water and energy, and generates more waste, than any other huge metro.


Via Luca Baptista
Semiotic Sorceress's insight:

"That's according to a new study published in Proceedings of the National Academy of Sciences. The large research team, led by Christopher A. Kennedy of the University of Toronto, examined how 27 "megacities" (metropolitan areas with more than 10 million people) metabolize resources and create waste. Together these monster cities consume 9.3 percent of the world's electricity and produce 12.6 percent of the world's waste—even though they contain only 6.7 percent of the world's population."

Mistaken Identity: 'Sea Anemone' Is Actually New Type of Animal

Mistaken Identity: 'Sea Anemone' Is Actually New Type of Animal | Semiotic Adventures with Genetic Algorithms | Scoop.it
Lurking in the deep sea is a marine creature thought to be one of the world's largest sea anemones. But the animal, which has tentacles measuring more than 6 feet (2 meters) long, isn't an anemone but rather the first known organism in a new order of animals, according to new research. In doing so, they examined the DNA of Boloceroides daphneae — discovered in 2006 in the deep Pacific Ocean — and found the creature stood out as not fitting on the sea anemone tree of life at all. Researchers have now renamed the species Relicanthus daphneae, placing it into a new order (the equivalent of Carnivoria for mammals, Crocodilia for reptiles or Actiniaria for sea anemones) within the subclass Hexacorallia, which also includes anemones, black corals and stony corals.

Do Bees Really Die After They Sting You?

Do Bees Really Die After They Sting You? | Semiotic Adventures with Genetic Algorithms | Scoop.it
Short answer for the overwhelmed readers with little time on their hands: Yes, some do.



Longer answer:

The process of stinging and dying is called autotomizing and only various honey bees are susceptible, not honey wasps or yellowjackets or the Honey Nut Cheerios bee. Here’s how it works: When the bee stings you, its stinging apparatus screws into your skin like a corkscrew. The bee is too weak to pull it out without tearing its abdomen apart. Interestingly, when the bee stings an animal or
