Earthquakes that happen deep beneath the earth’s surface have long been enigmatic to geologists. Now researchers from Brown University have shown strong evidence that water squeezed out of a mineral called lawsonite could trigger these mysterious quakes. (more…)

A person’s psyche and skin may rebel against seasonal changes, the skin thus needs to be nurtured to give it the healthy characteristics to boost one’s psyche. A change in the skin care routine is thus necessary during winter to prevent drying up and flaking of the skin. To look attractive in the winter the following skin care tips should be practiced:
Use of good moisturizers
Heavier, richer moisturizers help prevent environmental conditions and prevent moisture loss in over-heated rooms. Moisturizers with lanolin oils restores the skin’s natural protective layer and moisture balance to keep the skin soft. Products with alpha hydroxyl acids should be substituted with products enriched with natural cocoa butter and vitamin E which provides deep and long-lasting moisture and smoothies away dullness.

Pathogen leads to dehydration, other ill effects
The fungal infection that killed a record number of amphibians worldwide leads to deadly dehydration in frogs in the wild, according to results of a new study.
High levels of an aquatic, chytrid fungus called Batrachochytrium dendrobatidis (Bd) disrupt fluid and electrolyte balance in wild frogs, the scientists say, severely depleting the frogs’ sodium and potassium levels and causing cardiac arrest and death. (more…)
*Oldest known wild bird in U.S. returns to Midway to raise chick*
MIDWAY ATOLL — The oldest known U.S. wild bird – a coyly conservative 60 — is a new mother.
The bird, a Laysan albatross named Wisdom, was spotted a few weeks ago with a chick by John Klavitter, a U.S. Fish and Wildlife Service biologist and the deputy manager of the Midway Atoll National Wildlife Refuge.
The bird has sported and worn out 5 bird bands since she was first banded by U.S. Geological Survey scientist Chandler Robbins in 1956 as she incubated an egg. Chandler rediscovered Wisdom in 2001. In 1956, he estimated Wisdom to be at least 5 years old then since this is the earliest age at which these birds breed, though they more typically breed at 8 or 9 after an involved courtship lasting several years. This means, of course, that Wisdom is likely to be in her early sixties. (more…)
Psychedelically colored wolves depicted by thermal imaging will shed light on how mange affects the survival, reproduction and social behavior of wolves in Yellowstone National Park.
About a quarter of the wolf packs in the park are afflicted with sarcoptic mange, a highly contagious canine skin disease caused by mites that burrow into the skin causing infections, hair loss, severe irritation and an insatiable desire to scratch.
The resulting hair loss and depressed vigor of the wolves leaves them vulnerable to hypothermia, malnutrition and dehydration, which can eventually lead to death, said Paul Cross, a U.S. Geological Survey disease ecologist, who leads the project along with Doug Smith of Yellowstone National Park.
