Stirred, not shaken: Bio-inspired cilia mix medical reagents at small scales
The equipment used for biomedical research is shrinking, but the physical properties of the fluids under investigation are not changing. view more (2009-07-01)
Asteroid attack 3.9 billion years ago may have enhanced early life on Earth, says CU-Boulder study
The bombardment of Earth nearly 4 billion years ago by asteroids as large as Kansas would not have had the firepower to extinguish potential early life on the planet and may even have given it a boost, says a new University of Colorado at Boulder study. view more (2009-05-21)
First complete image created of Himalayan fault, subduction zone
An international team of researchers has created the most complete seismic image of the Earth's crust and upper mantle beneath the rugged Himalaya Mountains, in the process discovering some unusual geologic features that may explain how the region has evolved. view more (2009-09-14)
Sierra Nevada rose to current height earlier than thought, geologists say; implications for modeling global climate
Geologists studying deposits of volcanic glass in the western United States have found that the central Sierra Nevada largely attained its present elevation 12 million years ago, roughly 8 or 9 million years earlier than commonly thought. view more (2008-04-24)
Finding trapped miners
University of Utah scientists devised a new way to find miners trapped by cave-ins. The method involves installing iron plates and sledgehammers at regular intervals inside mines, and sensitive listening devices on the ground overhead. view more (2009-03-26)

'Roof of the world' tells tale of colliding continents, Earth's interior
Geologists have learned that the height of the Tibetan Plateau, a vast, elevated region of central Asia sometimes called "the roof of the world," has remained remarkably constant for at least 35 million years. view more (2006-02-09)
Unusual mechanism of the Ambrym and Pentecost Islands earthquake in Vanuatu
The Vanuatu island arc, in the South-West Pacific, is 1 700 km long. It corresponds to a convergence zone where the Australian plate is slipping eastwards under the North Fiji Basin, which is part of the Pacific plate, thus generating earthquakes. On 26 November 1999, the central islands of Vanuatu, particularly Ambrym and Pentecost, were strongly... view more... (2004-02-20)
Melting defects could lead to smaller, more powerful microchips
As microchips shrink, even tiny defects in the lines, dots and other shapes etched on them become major barriers to performance. Princeton engineers have now found a way to literally melt away such defects, using a process that could dramatically improve chip quality without increasing fabrication cost. view more (2008-05-05)
University of Pennsylvania Researchers Demonstrate a Flexible, One-Step Assembly of Nanoscale Structures
Scientists at the University of Pennsylvania have created a one-step, repeatable method for the production of functional nanoscale patterns or motifs with adjustable features, size and shape using a single master "plate." view more (2008-07-28)
New Findings Show Diverse, Wet Environments on Ancient Mars
Mars once hosted vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life, according to two new studies based on data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) and other instruments on board NASA's Mars Reconnaissance Orbiter (MRO). view more (2008-07-17)

Foot-dragging Mars rover finds Yellowstone-like hot spring deposits
Deposits of nearly pure silica discovered by the Mars Exploration Rover Spirit in Gusev Crater formed when volcanic steam or hot water (or maybe both) percolated through the ground. view more (2008-05-23)
Creating Ideal Neural Cells for Clinical Use
Investigators at the Burnham Institute for Medical Research (Burnham) have developed a protocol to rapidly differentiate human embryonic stem cells (hESCs) into neural progenitor cells that may be ideal for transplantation. view more (2009-04-14)
Portion-control dishes may help obese diabetics lose weight
A plate and cereal bowl with markers for proper portion sizes appear to help obese patients with diabetes lose weight and decrease their use of glucose-controlling medications. view more (2007-06-26)
Airbus A380 Mega-liner: Weight Savings by Titanium
The titanium parts implemented in the new Airbus A380 aircraft will constitute about 9 % by weight. The new mega-liner basic version is able to transport 555 passengers over a distance of 14.800 kilometres at a speed of Mach 0.85. Length and wingspan do not exceed 80m. Airbus aircraft has been using titanium alloys from the very beginning. Due to... view more... (2003-06-23)
Embryonic Stem Cells Thrive When Shaken
Embryos spend much of their time in the womb bobbing along with a mother's movement, and, surprisingly enough, new research from the Georgia Institute of Technology and Emory University suggests that embryonic stem cells may develop much better under similarly shaky conditions. view more (2007-09-11)
Crabs' memory of pain confirmed by Queen's academic
New research published by a Queen's University Belfast academic has shown that crabs not only suffer pain but that they retain a memory of it. view more (2009-03-27)
Lunar rocks suggest meteorite shower
New age measurements of lunar rocks returned by the Apollo space missions have revealed that a surprising number of the rocks show signs of melting about 3.9 billion years ago, suggesting that the moon - and its nearby neighbor Earth - were bombarded by a series of large meteorites at that time. view more (2006-04-13)
Scientists penetrate fossil magma chamber beneath intact ocean crust - achieving scientific 'first'
Approximately 800 km west of Costa Rica an international team of scientists aboard the research drilling ship JOIDES Resolution hasĄ-for the first time-recovered black rocks known as gabbros from intact ocean crust. view more (2006-04-21)
