Mutant champions save imperiled species from
almost-certain extinction:
Species facing widespread and rapid environmental
changes can sometimes evolve quickly enough to dodge the
extinction bullet. Populations of disease-causing
bacteria evolve, for example, as doctors flood their “environment,”
the human body, with antibiotics. Insects, animals and
plants can make evolutionary adaptations in response to
pesticides, heavy metals and overfishing. (U.

Hawaiian Islands are dissolving:
Someday, Oahu’s Koolau and Waianae mountains will be
reduced to nothing more than a flat, low-lying island
like Midway. But erosion isn’t the biggest culprit.
Instead, scientists say, the mountains of Oahu are
actually dissolving from within. (Brigham Young U.)

Changes in Sleep Architecture Increase Hunger, Eating:
A new study shows that both length of time and

stages are associated with decreased metabolic rate,
increased hunger, and increased intake of calories (specifically
from fat and carbohydrates). The findings suggest an
explanation for the association between sleep problems
and obesity. (APS)

Salt Seeds Clouds in the Amazon Rainforest:
It’s morning, deep in the Amazon jungle. In the still
air innumerable leaves glisten with moisture, and fog
drifts through the trees. As the sun rises, clouds
appear and float across the forest canopy … but where do
they come from? Water vapor needs soluble particles to
condense on. Airborne particles are the seeds of liquid
droplets in fog, mist, and clouds. (LBNL)

Deep-Sea Crabs Grab Grub Using UV Vision:
Crabs living half-a-mile down in the ocean, beyond the

way to ensure they grab healthy grub, not poison. (Duke

Unraveling the mysteries of exotic superconductors:
In traditional electrical lines, a significant amount of
energy is lost while the energy travels from its source to
homes and businesses due to resistance. Superconductors,
materials that when cooled have zero electric resistance,
have the promise of someday increasing the efficiency of
power distribution, but more must still be learned about
superconductors before they can be widely used for that
purpose. (Ames L.)

Researchers Demonstrate Possible Primitive Mechanism of
Chemical Info Self-Replication: When scientists

researchers at the California Institute of Technology
(Caltech) have now shown that a different mechanism can
also be used to copy sequence information. (Caltech)

Caltech Researchers Use Stalagmites to Study Past Climate

There is an old trick for remembering the difference

might also fill a hole in our understanding of Earth's
climate system and how that system is likely to respond to
the rapid increase in atmospheric carbon dioxide since
preindustrial times. (Caltech)

Genetic analysis of ancient ‘Iceman’ mummy traces ancestry

including the cause of his death (an arrow to the back)
and his last meal (ibex meat). An analysis of the corpse’s

his entire life in the Tyrol area where his body was
found. Now they’re delving deeper to unearth more clues in
the mummy’s DNA. (Stanford U.)
