Animal Testing Is Bad Science: Point/Counterpoint | PETA.org - 0 views

  • Studies published in prestigious medical journals have shown time and again that animal experimenters are often wasting lives—both animal and human
  • medical historians report that improved nutrition, sanitation, and other behavioral and environmental factors—rather than anything learned from animal experiments—
  • The fact is that we already do test new drugs on people.
  • ...11 more annotations...
  • someone will always be the first human to be tested on.Because animal tests are so unreliable, they make those human trials all the more risky
  • 92 percent of all drugs that are shown to be safe and effective in animal tests fail in human trials because they don’t work or are dangerous.
  • half are relabeled because of side effects that were not identified in animal tests. 
  • prescription drugs kill 100,000 people each year, making them our nation's fourth-biggest killer.
  • The only U.S. law that governs the use of animals in laboratories—the Animal Welfare Act—allows animals to be burned, shocked, poisoned, isolated, starved, forcibly restrained, addicted to drugs, and brain-damaged
  • pain-killers are not even required. 
  • Because the Act specifically excludes rats, mice, birds and cold-blooded animals, more than 95 percent of the animals used in laboratories are not subject to the minimal protections provided by federal laws
  • scientists have used human brain cells to develop a model "microbrain," which can be used to study tumors, as well as artificial skin and bone marrow. We can now test irritancy on protein membranes, produce and test vaccines using human tissues, and perform pregnancy tests using blood samples instead of killing rabbits
  • Today, one can even become a board-certified surgeon without harming any animals.
  • In the United Kingdom , it's against the law for medical (and veterinary) students to practice surgery on animals.
  • They believe it is acceptable to harm animals because they are weaker, they look different and because their pain is less important than humans’.

Why to Avoid TV Before Age 2 - HealthyChildren.org - 0 views

  • Imagine a ball in real life and a ball on TV. Infants are developing 3-dimensional vision. The world of the screen exists in 2 dimensions, so the ball is just a flat, shaded circle. If you roll a ball across the floor it proceeds in a single motion, slowing gradually until it stops. The same action on TV is broken up—you see the ball leave someone’s hand, then there’s a shot of it in motion, then a picture of the ball at rest. If your infant wants to grab a ball in real life he’ll lunge for it, grasp at it, or crawl after it. The stuff on the screen just disappears, to be replaced by other stuff; you can never get your hands (or mouth) on it.
  • t’s a bad idea for children to watch TV before age 2.

Amoeba Genome Shows Evolution of Complex Life :: UC Davis News & Information - 0 views

  • "We tend to think of protists (single-celled organisms) as 'simple' and humans as 'complex' -- but the Naegleria genome shows us that much of this complexity arose really early in evolution," said Scott Dawson, assistant professor of microbiology at UC Davis. Dawson is senior author on the paper analyzing the genome of Naegleria gruberi, published in the March issue of the journal Cell. The team also included UC Davis graduate students Michael Cipriano and Jonathan Pham. Dawson had initially proposed N. gruberi as a candidate for genome sequencing back in 2004 while he was a postdoctoral researcher at UC Berkeley. N. gruberi slurps around in mud as an amoeba but when food runs low it sprouts two whip-like tails, or flagellae, and swims rapidly away. It can also transform into a hard, resistant cyst to wait out bad conditions. Most previous efforts to sequence the genomes of protozoa have focused on parasitic organisms such as the malaria parasite. "Because it's free living, it can tell us a lot about early life -- it has genes to do all these different things," Dawson said. The analysis shows that N. gruberi has 15,727 genes that code for proteins, compared to about 23,000 in humans. With those genes, the organism can eat and reproduce, crawl or swim, live with or without oxygen, and organize itself internally much as a human cell does.
