A glimpse at the Earth's crust deep below the Atlantic
Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor, says geologist Dr Bram Murton of the National Oceanography Centre, Southampton. view more (2009-11-13)
UMaine teams with fishermen to study affects of trawling on seafloor ecology
Working in cooperation with Maine trawler captain Cameron McLellan and the Gulf of Maine Research Institute, UMaine graduate student Emily Knight and UMaine Marine Science professor Les Watling recently completed a long-term study that examines the effects of groundfish trawling on the complex ecology of the sea floor in the Gulf of Maine. view more (2006-02-08)
No drop in IQ seen after bypass for child heart surgery
The use of cardiopulmonary bypass does not cause short-term neurological problems in children and teenagers after surgery for less complex heart defects, according to pediatric researchers. view more (2008-11-11)
September Issue Tip-Sheet
An e-fab way for making the micro world A new manufacturing technique that has produced what researchers believe is the world's narrowest chain could open a whole world of new micro-mechanical devices. The technique, known as EFAB (electrochemical fabrication), is much faster and quicker than other microfabrication techniques, allowing the... view more... (1999-08-31)
Researchers Create Catalysts for Use in Hydrogen Storage Materials
A team of scientists from Virginia Commonwealth University, the University of Uppsala in Sweden, and the Savannah River National Laboratory have identified that carbon nanostructures can be used as catalysts to store and release hydrogen, a finding that may point researchers toward developing the right material for hydrogen storage for use in cars. view more (2009-03-25)
Researchers develop guidelines to establish identity of genes responsible for common, complex diseases
Scientists from Imperial College London, the Medical Research Council, Case Western Reserve University, USA and the Hammersmith Hospital have developed guidelines which scientists can use as a benchmark for proof of identification of the multiple genes responsible for common, complex diseases. Predisposition to common conditions such as asthma,... view more... (2002-12-18)
Mathematician uses topology to study abstract spaces, solve problems
Studying complex systems, such as the movement of robots on a factory floor, the motion of air over a wing, or the effectiveness of a security network, can present huge challenges. Mathematician Robert Ghrist at the University of Illinois at Urbana-Champaign is developing advanced mathematical tools to simplify such tasks. view more (2006-08-16)
Human embryonic stem cells
Human embryonic stem cells (hESC) provide a potentially unlimited source of oral mucosal tissues that may revolutionize the treatment of oral diseases. view more (2009-04-06)
Instruction Manuals: First Text then Pictures
Delft research on efficiency of text, images and animations in instruction manuals Instruction Manuals: First Text then Pictures In instruction manuals, the use of text is most efficient for short-term learning and images are most efficient for the longer term. This is one of the conclusions from the thesis of Piet Westendorp, which he defended on... view more... (2002-06-11)
NYU, Salk Institute neuroscientists offer new path for measuring visual responses to complex images
Neuroscientists at New York University and the Salk Institute have developed a new technique for measuring visual responses to complex images. The method consists of building a model based on cell responses to a range of stimuli, then asking how accurate the model is by comparing the model predictions with the actual responses of a cell to... view more...

A single water molecule acting as gate keeper
How do the bonds cells form with their environments rupture? What enables some cells to migrate? It is known since quite a while that cells can have complex mechanical interactions with their environments. Not only the biochemical but also the physical properties of their environment can thus have significant impact on cell behavior and even gene... view more... (2004-11-12)
Research leading to tools for managing bovine respiratory disease complex
Bovine respiratory disease complex has multiple causes. It's sometimes hard to classify and predict. It also costs the beef industry more than any other disease -- an estimated $690 million in 2006, according to one report. view more (2008-02-28)
Help for bleeding hearts: new research links a third protein to blood-clotting disorders
Studying receptors on the surface of blood platelets, sticky cells that cause blood to clot, has given one Rockefeller researcher new insight into potential causes and treatments for certain cardiovascular diseases. view more (2006-04-20)
US soldiers in Iraq fighting drug-resistant bacteria after injuries
US soldiers in Iraq do not carry the bacteria responsible for difficult-to-treat wound infections found in military hospitals treating soldiers wounded in Iraq. view more (2007-05-16)
Research identifies 3-D structure of key nuclear pore building block
The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside. view more (2009-06-08)
Scientists Create the First Synthetic Nanoscale Fractal Molecule
From snowflakes to the leaves on a tree, objects in nature are made of irregular molecules called fractals. Scientists now have created and captured an image of the largest man-made fractal molecule at the nanoscale. view more (2006-05-12)
Novel enzyme inhibitor paves way for new cancer drug
Combining natural organic atoms with metal complexes, scientists at The Wistar Institute have developed a new type of enzyme inhibitor capable of blocking a biochemical pathway that plays a key role in cancer development. view more (2008-05-16)
Does life exist on other planets?
Recent research argues that an atmosphere rich in oxygen is the most likely source of energy for complex life to exist anywhere in the Universe, thereby limiting the number of places life may exist. view more (2005-06-20)
Aiding decision making for baby Charlotte and baby Luke (p 1462)
An editorial in this week's issue of THE LANCET discusses the complex issues surrounding decisions to withhold medical treatment for profoundly ill patients, recently highlighted by the UK cases of 11-month-old Charlotte Wyatt and 9-month-old Luke Winston-Jones. view more (2004-10-20)
Simple explanation for complex pattern of feather development
Biologists testing a mathematical model of the mechanism birds use to control the growth of complex feathers found that plumed feather structures involve the coordination of at least two genes that activate and that inhibit barb growth. view more (2005-08-16)
