POPSNano Superbug-Killers -Identifies Bacteria That Have Become Resistant to Antibiotics The drugs to be tested work by latching onto the bacteria and literally ripping its cell wall to pieces, exposing the vulnerable core to destruction by the surrounding environment. When a drug can latch onto the mucopeptide, it bends the cantilever and alters the reflection of the laser. The response to the drug can be observed almost instantly. While this technique only works for surface-latching antibiotics (by no means the only antibiotic mechanism), Professor McKendry and colleagues are already planning an upgrade where entire bacterial cells will be pinned to the nano-lever and stretched by drugs.

POPSWhat happens when you cry? " one study collected both reflex tears and emotional tears (after peeling an onion and watching a sad movie, respectively). When scientists analyzed the content of the tears, they found each type was very different. Reflex tears are generally found to be about 98 percent water, whereas several chemicals are commonly present in emotional tears First is a protein called prolactin, which is also known to control breast milk production. Adrenocorticotropic hormones are also common and indicate high stress levels. The other chemical found in emotional tears is leucine-enkephalin, an endorphin that reduces pain and works to improve mood. Of course".

POPSSpray-on solar cells
continues: "I think these materials have a lot more potential than traditional silicon," Jiang said. "They could be sprayed on any surface that is exposed to sunlight — a uniform, a car, a house." Another type of solar cell scientists are trying to develop are dye-sensitized cells, which so far are slightly less efficient than silicon cells, which convert about 12 percent of the sunlight that hits them into electricity. Typical organic cells only manage about 3 percent, prompting some scientists to caution praise for their use. Jiang and her colleagues made 20 tiny cells — each the size of a lower case "o" in standard 12-point print — and joined them together in an array to power the microscopic detector. The detector needs a 15-volt power source to work, and so far Jiang's solar cell array can provide about half of that — up to 7.8 volts in the lab tests she and her colleagues did. The next step, Jiang said, is to increase the voltage and then combine the tiny solar array

POPSExtreme Early Puberty On The Rise I can't seem to find anything in English yet, (so the wording may be odd in the clip, it's a translated page) but there has been a dramatic rise in the number of very young girls, coming into early puberty these last years. Girls as young as 4 years old (!!!), have been reported to be developing breasts and growing pubic hair. Something is terribly wrong. Pesticides? Plastics? GMO's? Chemicals? I don't know, but this is an ominous trend, we should watch carefully.

POPSFollowing The Trail Of Toxic E-Waste
This is smuggling. This is illegal," says Jim Puckett, founder of the Basel Action Network, a group working to stop the dumping of toxic materials in poor countries that certifies ethical e-waste recyclers in the United States. "A lot of people are turning a blind eye here. And if somebody makes enough noise, they're afraid this is all going to dry up." E-waste workers in Guiyu, China, where Pelley's team videotaped, put up with the dangerous conditions for the $8 a day the job pays. They use caustic chemicals and burn the plastic parts to get at the valuable components, often releasing toxins that they not only inhale, but release into the air, the ground and the water. Potable water must now be trucked into Guiyu and scientists have discovered that the city has the highest levels of cancer-causing dioxins in the world. Pregnancies in Guiyu are six times more likely to result in miscarriages, and seven out of 10 children there have too much lead in their blood. Allen Hershkowitz

POPSTruth Behind the statistics Horrific isn't it? UK laboratories last year forcibly subjected more than 3 million individual animals – all with feelings and fears – to some of the most needless and often gruesome experiments imaginable. The pain and suffering endured by many of these dogs, cats, rabbits, guinea pigs and other animals is even referred to by the vivisectors themselves as "severe". Many animals are cut open without anaesthetics. Their skin and eyes are burned with chemicals, and ultimately they are poisoned, gassed, electrocuted or otherwise killed for the sake of "science".
