Meteorite search update
Investigation of the fireball that lit up the skies of Alberta and Saskatchewan on November 20 has determined that an asteroid fragment weighing approximately 10 tonnes entered the Earth's atmosphere over the prairie provinces last Thursday evening.   view more (2008-11-26)

Very cold ice films in laboratory reveal mysteries of universe
The universe is full of water, mostly in the form of very cold ice films deposited on interstellar dust particles, but until recently little was known about the detailed small scale structure.   view more (2008-11-06)

Rocks could be harnessed to sponge vast amounts of CO2 from air, says study
Scientists say that a type of rock found at or near the surface in the Mideast nation of Oman and other areas around the world could be harnessed to soak up huge quantities of globe-warming carbon dioxide.   view more (2008-11-06)

Seismic response to natural gas anomalies in crystalline rocks
The research done at the Chinese Academy of Geological Sciences has shown that after geochemical experiments, the porosity of crystalline rocks in the middle crust increases sharply due to water-rock interaction.   view more (2008-11-05)

MIT researchers find clues to planets' birth
Meteorites that are among the oldest rocks ever found have provided new clues about the conditions that existed at the beginning of the solar system, solving a longstanding mystery and overturning some accepted ideas about the way planets form.   view more (2008-10-31)

21st century detective work reveals how ancient rock got off to a hot start
A new technique using X-rays has enabled scientists to play 'detective' and solve the debate about the origins of a three billion year old rock fragment.   view more (2008-10-16)

Sensitive laser instrument could aid search for life on Mars
Minuscule traces of cells can be detected in a mineral likely present on Mars, a new study shows. The results, obtained using a technique developed at the U.S. Department of Energy's Idaho National Laboratory, could help mission scientists choose Martian surface samples with the most promise for... view more (2008-10-16)

MIT finds young planets stay hotter longer
Hot, young planets may be easier to spot because they stay that way longer than astronomers have thought, according to new work by MIT planetary scientist Linda Elkins-Tanton.   view more (2008-10-16)

Researchers uncover world's oldest fossil impression of a flying insect
While paleontologists may scour remote, exotic places in search of prehistoric specimens, Tufts researchers have found what they believe to be the world's oldest whole-body fossil impression of a flying insect in a wooded field behind a strip mall in North Attleboro, Mass.   view more (2008-10-15)

Lunar Prospecting Robot To Be Field Tested on Hawaii's Mauna Kea
The cool, rocky slopes of Mauna Kea, a dormant volcano that is Hawaii's highest mountain, will serve as a stand-in for the moon as researchers from Carnegie Mellon University's Robotics Institute, NASA and other organizations test a robot designed for lunar prospecting.   view more (2008-10-15)

Paleozoic 'sediment curve' provides new tool for tracking sea-floor sediment movements
As the world looks for more energy, the oil industry will need more refined tools for discoveries in places where searches have never before taken place, geologists say.   view more (2008-10-03)

Oldest Known Rock on Earth Discovered
Canadian bedrock more than 4 billion years old may be the oldest known section of the Earth's early crust.   view more (2008-09-29)

Lava flows reveal clues to magnetic field reversals
Ancient lava flows are guiding a better understanding of what generates and controls the Earth's magnetic field - and what may drive it to occasionally reverse direction.   view more (2008-09-29)

100 million years AD
Jan Zalasiewicz, a lecturer in geology at the University of Leicester, has published a new study looking at the lasting impression made by mankind -100 million years hence.   view more (2008-09-26)

Ocean floor geysers warm flowing sea water
An international team of earth scientists report movement of warmed sea water through the flat, Pacific Ocean floor off Costa Rica. The movement is greater than that off midocean volcanic ridges. The finding suggests possible marine life in a part of the ocean once considered barren.   view more (2008-09-23)

Astronomers discover missing link for origin of comets
An international team of scientists that includes University of British Columbia astronomer Brett Gladman has found an unusual object whose backward and tilted orbit around the Sun may clarify the origins of certain comets.   view more (2008-09-05)

Cosmic connections: Imperial scientist locates the origin of cosmic dust
The research, published in the journal Geology, shows that some of the cosmic dust falling to Earth comes from an ancient asteroid belt between Jupiter and Mars. This research improves our knowledge of the solar system, and could provide a new and inexpensive method for understanding space.   view more (2008-09-03)

Explosives go "green"
Certain explosives may soon get a little greener and a little more precise.    view more (2008-08-29)

Why is Greenland covered in ice?
There have been many reports in the media about the effects of global warming on the Greenland ice-sheet, but there is still great uncertainty as to why there is an ice-sheet there at all.   view more (2008-08-28)

Yellowstone's Ancient Supervolcano: Only Lukewarm?
The geysers of Yellowstone National Park owe their eistence to the "Yellowstone hotspot"--a region of molten rock buried deep beneath Yellowstone, geologists have found.   view more (2008-08-28)

Normalizing tumor vessels to improve cancer therapy
Chemotherapy drugs often never reach the tumors they're intended to treat, and radiation therapy is not always effective, because the blood vessels feeding the tumors are abnormal-"leaky and twisty" in the words of the late Judah Folkman, MD, founder of the Vascular Biology program at... view more (2008-08-26)

Measuring Calcium in Serpentine Soils
Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple... view more (2008-08-20)

UC Riverside researcher develops novel method to grow human embryonic stem cells
The majority of researchers working with human embryonic stem cells (hESCs) - cells which produce any type of specialized adult cells in the human body - use animal-based materials for culturing the cells. But because these materials are animal-based, they could transmit viruses and other pathogens... view more (2008-08-20)

Rock art marks transformations in traditional Peruvian societies
Most rock paintings and rock carvings or petroglyphs were created by ancient and prehistoric societies. Archaeologists have long used them to gain clues to the way of life of such peoples.   view more (2008-08-05)

Snapshot of past climate reveals no ice in Antarctica millions of years ago
A snapshot of New Zealand's climate 40 million years ago reveals a greenhouse Earth, with warmer seas and little or no ice in Antarctica, according to research published this week in the journal Geology.    view more (2008-07-29)
