Sweden's first woman Ph.D in Steel Construction
Wall elements of the type studied in the doctoral dissertation Column Buckling with Restraint from Sandwich Wall Elements are often used in industrial construction together with a steel frame. The dissertation, to be defended by Eva Hedman-Pétursson on October 25 at Lule'å University... view more (2001-10-23)

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)

Science Team Determines Composition of Asteroid Itokawa
Itokawa, a spud-shaped, near-Earth asteroid, consists mainly of the minerals olivine and pyroxene, a mineral composition similar to a class of stony meteorites that have pelted Earth in the past.   view more (2006-06-02)

Discovery of a mechanism that regulates cell movement
A study performed by researchers at the Institute for Research in Biomedicine (IRB Barcelona), in collaboration with researchers at the Instituto de Biología Molecular of the CSIC, reveal a mechanism that controls the movement of cells in a tissue by regulating cell adhesion.   view more (2008-07-21)

More 'functional' DNA in genome than previously thought
Surrounding the small islands of genes within the human genome is a vast sea of mysterious DNA. While most of this non-coding DNA is junk, some of it is used to help genes turn on and off.   view more (2007-12-12)

ASU professor 'follows the elements' to understand evolution in ancient oceans
In the search for life beyond Earth, scientists 'follow the water' to find places that might be hospitable. However, every home gardener knows that plants need more than water, or even sunshine.   view more (2008-12-08)

Supplements are not nutritious
Selenium supplementation, for example in mineral tablets, might not be that beneficial for the majority of people according to researchers writing in the open access journal Genome Biology.   view more (2008-04-07)

Measurement of stellar age from uranium decay
For the first time, an international team (led by Roger Cayrel, from Paris Observatory), could measure one uranium line in absorption in a star. This observation has several important implications. It is a great discovery, obtained thanks to the high resolution spectrograph UVES, assembled on one... view more (2001-02-05)

Novel treasure hunt explores Earth and Mineral Sciences Library
Geocaching, a combination of a treasure hunt, orienteering with the aid of geographic information systems (GPS) and a little bit of learning, seems perfect for an Earth Sciences library.   view more (2005-10-17)

KGI professor contributes new insights on 'jumping genes'
Keck Graduate Institute (KGI) today announced that Dr. Animesh Ray, KGI professor and director of KGI's PhD program, has published a paper in the international online journal PLoS ONE that sheds new light on the evolution of moveable genetic elements, or "jumping genes."   view more (2007-10-09)

Mars Sample Return: bridging robotic and human exploration
The first robotic mission to return samples to Earth from Mars took a further step toward realisation with the recent publication of a mission design report by the iMARS Working Group. The report defines key elements of the future internationally-funded mission involving the cooperation of ESA,... view more (2008-07-23)

Understanding the Mediterranean
As millions of holidaymakers will testify, the Mediterranean is uniquely clear - and blue - unlike the cloudy grey of many coastal waters. But how many of its grateful bathers realise that the Med is so crystal clear because it's the ocean equivalent of the Sahara desert?   view more (2004-12-01)

Universe contains more calcium than expected
The universe contains one and a half times more calcium than previously assumed. This conclusion was drawn by astronomers of the SRON Netherlands Institute for Space Research, after observations with ESA's XMM-Newton X-ray observatory.   view more (2007-02-07)

FSU physicist takes a trip to nuclear 'island of inversion'
Far from the everyday world occupied by such common elements such as gold and lead lies a little-understood realm inhabited by radioactive, or unstable, elements.   view more (2007-08-10)

Large European study finds gene variant is no strong risk factor for osteoporosis
Variations in a number of different genes and environmental factors affect an individual's risk for osteoporosis.   view more (2006-02-21)

Grand Canyon may be as old as dinosaurs, says new study
New geological evidence indicates the Grand Canyon may be so old that dinosaurs once lumbered along its rim, according to a study by researchers from the University of Colorado at Boulder and the California Institute of Technology.   view more (2008-04-11)

UAB research could improve the prognosis and treatment of lung cancer
A group of scientists led by Professor Xavier Parés of the Department of Biochemistry and Molecular Biology at Universitat Autònoma de Barcelona, has published a research on AKR1B10, an enzyme that is detected in large quantities only in lung cancers, particularly those caused by... view more (2008-01-08)

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)

Frequent hemodialysis at night may improve some outcomes for patients with end-stage kidney disease
Patients who received hemodialysis at night six times a week for treatment of end-stage kidney disease had improvements on certain outcomes, including reduced need for blood pressure medications and improvement in selected quality of life measures, compared to patients who received conventional... view more (2007-09-19)

Under pressure, vanadium won't turn down the volume
Scientists at Carnegie's Geophysical Laboratory have discovered a new type of phase transition—a change from one form to another—in vanadium, a metal that is commonly added to steel to make it harder and more durable.   view more (2007-02-21)

Stellar forensics with striking new image from Chandra
A spectacular new image shows how complex a star's afterlife can be. By studying the details of this image made from a long observation by NASA's Chandra X-ray Observatory, astronomers can better understand how some stars die and disperse elements like oxygen into the next generation of stars and... view more (2007-10-24)

Seismologists see Earth's interior as interplay between temperature, pressure and chemistry
Seismologists in recent years have recast their understanding of the inner workings of Earth from a relatively benign homogeneous environment to one that is highly dynamic and chemically diverse.   view more (2007-10-26)

Mathematical model for the vibrato
As her PhD defended at the Public University of Navarre, telecommunications engineer Ixone Arroabarren has analysed the vibrato, one of the most important tools of classical singers. The study applies both to the teaching of singing in music as well as to the medical treatment of voice pathologies.... view more (2004-08-18)

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)
