Few states in US require HPV vaccine

An examination of state vaccination requirements for adolescents finds that the human papillomavirus (HPV) vaccine is currently required in only two states, many fewer than another vaccine associated with sexual transmission (hepatitis B) and another primarily recommended for adolescents (meningococcal conjugate), according to a new study

Lightening can Warp Rocks at Their Core

When a high energy lightening strike bombards a rock, it can heat the rock more than 3,000 degree Fahrenheit which can be twice as hot as lava and deforms not only the appearance of the rock, also the chemical bond that holds it together.

When this happens, the lightening zapped rock becomes covered in natural glasses called fulgurites. In the new study, the researchers took a microscopic look at the quartz fulgurites and found a thin layer of warped quartz crystal underneath the glassy quartz, induced by the high pressure of the strike. This warped layer consists of distinct, parallel and remarkably straight lines and can only be seen with intense magnification. This features control the fundamental structure of the rocks.

Abusive men put female partners at greater sexual risk

Men who were physically and sexually abusive to women were more likely than non-abusive men to engage in behaviors that exposed them and their partners to sexual transmission infections.

Entire Genomes of Wooly Mammoth Mapped

A international team of researcher has sequenced the nearly complete genome of two Siberian wooly mammoths. It revealed most complete picture of wooly mammoth to date.It includes the new information about the species' evolutionary history and the conditions that led to its mass extinction at the end of the Ice Age.

13 year study suggests Bushmeat grows with Economy

Comprehensive results of 13 years of one of the longest continuously running studies of commercial hunting activity have been published. The researchers recorded more than 197,000 animal carcasses for sale and analyzed market patterns in relation to political, economic and legal factors in the country of Equatorial Guinea in Central Africa.

Parasitized spider makes bed for its natural enemy, wasp larva

An ichneumonid parasitic wasp seizes control of the parasitized spider and exploits its 'resting web' building behavior as seen before moulting, scientists have discovered. Researchers examining the threads’ force, found that the web produced through parasitic manipulation is more robust than the resting web. Given that the wasp induces a behavior inherent in the spider, revealing the molecular mechanism of the web manipulation is likely to contribute to the practical application of spider silk.

Why it's hard to make a Bunny Mad

Rabbits have long been considered immune to prior disease, but recently scientists have shown that under certain circumstances they can get transmissible spongiform  encephalopathy (the scientific name of the fatal brain disease causes by prion). Two studies suggests what makes rabbits hard to infect with prions and how they resistance can be overcome.

Head of Brazilian frogs are venomous wepeons

It's no surprise that some frogs secrete poison from glands in their skin. But researchers have discovered the first two species of frog, both living in Brazil, that are actually venomous. Not only do the frogs produce potent toxins, but they also have a mechanism to deliver those harmful secretions into another animal using bony spines on their heads.
