NASA Challenge Seeks Ways to Use Mars’ Natural Resources for Astronauts
Published Oct 7, 2015 - 8:46:06 AM
Living off the land is different when the land is 140 million miles away, so NASA is looking for innovative ideas to use in situ (in place) Martian resources to help establish a human presence on the Red Planet.
History shows more big wildfires likely as climate warms
Published Oct 6, 2015 - 8:12:14 AM
The history of wildfires over the past 2,000 years in a northern Colorado mountain range indicates that large fires will continue to increase as a result of a warming climate, according to new study led by a University of Wyoming doctoral student.

Largest dinosaur population growth study ever shows how Maiasaura lived and died
Published Oct 5, 2015 - 10:43:07 AM
Decades of research on Montana's state fossil -- the "good mother lizard" Maiasaura peeblesorum - has resulted in the most detailed life history of any dinosaur known and created a model to which all other dinosaurs can be compared, according to new research published recently in the journal Paleobiology.
Signs of ancient megatsunami could portend modern hazard
Published Oct 5, 2015 - 8:10:33 AM
Scientists working off west Africa in the Cape Verde Islands have found evidence that the sudden collapse of a volcano there tens of thousands of years ago generated an ocean tsunami that dwarfed anything ever seen by humans. The researchers say an 800-foot wave engulfed an island more than 30 miles away. The study could revive a simmering controversy over whether sudden giant collapses present a realistic hazard today around volcanic islands, or even along more distant continental coasts. The study appears today in the journal Science Advances.
Asteroid impact, volcanism were one-two punch for dinosaurs
Published Oct 2, 2015 - 9:11:00 AM
Berkeley geologists have uncovered compelling evidence that an asteroid impact on Earth 66 million years ago accelerated the eruptions of volcanoes in India for hundreds of thousands of years, and that together these planet-wide catastrophes caused the extinction of many land and marine animals, including the dinosaurs.
Asteroids found to be the moon's main 'water supply'
Published Sep 30, 2015 - 8:39:35 AM
Water reserves found on the moon are the result of asteroids acting as "delivery vehicles" and not of falling comets as was previously thought. Using computer simulation, scientists from MIPT and the RAS Geosphere Dynamics Institute have discovered that a large asteroid can deliver more water to the lunar surface than the cumulative fall of comets over a billion year period. Their research is discussed in an article recently published in the journal Planetary and Space Science.

Taming hot flashes without hormones: What works, what doesn't
Published Sep 23, 2015 - 11:53:59 AM
Some three-quarters of North American women have menopausal hot flashes, but many cannot use hormones for medical reasons or choose not to. Numerous products and techniques are promoted for hot flashes, but do they work, and are they safe? To answer these questions, a North American Menopause Society (NAMS) panel of experts weighed the evidence and made recommendations in a position statement, "Nonhormonal management of menopause-associated vasomotor symptoms," published online today in the Society's journal, Menopause.

As wildland-urban interface grows, so does risk to people and habitats
Published Sep 16, 2015 - 9:21:06 AM
Humans and habitat intersect in the wildland-urban interface, or WUI, a geography that now includes about one-third of homes in the United States within just 10 percent of the nation's land area. Both numbers are growing, according to a new USDA Forest Service map book summarizing the extent of the nation's WUI nationally and by state. The maps give land managers, policy makers, fire managers and homeowners a valuable new source of information on housing density, land ownership, land cover and wildland vegetation cover in WUI areas in the contiguous United States.

The Alaska fire season -- before and after (satellite photos)
Published Sep 3, 2015 - 8:48:25 AM
The 2015 Alaska fire season has been particularly brutal this year. The fire season reached another milestone on Aug. 7 by surpassing the 5-million- mark in the number of acres burned so far this season. According to the Alaska Interagency Coordination Center's (AICC) daily situation report on Aug. 7, a total of 743 fires have burned 5,013,053.4 acres to date. That total ranks the 2015 fire season No. 3 on the list of the largest fire seasons on record. As of today, 768 fires have ravaged the state and 153 fires are currently active there. AICC notes as of August 13 that Alaska is moving into its annual seasonal rain pattern which should help to diminish fire activity across the state.
