Finely tuned laser strikes the right chord
Pulses of laser light can make molecules react in ways that are impossible using classical test-tube chemistry. Molecules vibrate, and each molecule has its own "tone," its own "melody." It's a question of finding the right key, and that is something that a "smart" laser beam can do. It can find its way to the... view more... (2002-05-30)
Baby Beetles Inspire Pitt Researchers to Build 'Mini Boat' Powered by Surface Tension
Inspired by the aquatic wriggling of beetle larvae, a University of Pittsburgh research team has designed a propulsion system that strips away paddles, sails, and motors and harnesses the energy within the water's surface. view more (2009-01-22)
Stanford study of sea squirt provides clue to human immune system
Until now, no one had demonstrated any concrete similarity between the vertebrate and invertebrate immune systems. The ramifications of the finding may shed light not only on the evolution of our immune system, but also on how we might better control some aspects of it, such as our natural killer cells. view more (2005-11-28)
Researchers rely on Newton's interference for new experiment
Most people think of Sir Isaac Newton as the father of gravity. But for Lawrence Livermore National Laboratory physicist Henry Chapman and his colleagues, Newton's "dusty mirror" experiment served as a launching pad for them to keenly watch the X-ray induced explosion of microscopic objects. view more (2007-08-09)
Wistar researchers invigorate 'exhausted' immune cells
In battles against chronic infections, the body's key immune cells often become exhausted and ineffective. Researchers at The Wistar Institute have found a way to restore vigor to these killer T cells by blocking a key receptor on their surface, findings that may advance the development of new therapies for diseases such as HIV, hepatitis B and C,... view more...

Bonn scientists discover new hemoglobin type
Scientists at the University of Bonn have discovered a new rare type of haemo-globin. Haemoglobin transports oxygen in the red blood corpuscles. view more (2008-03-18)
Premature vascular and bone changes occur in COPD patients
Researchers in the United Kingdom have found that patients with COPD, or chronic obstructive pulmonary disease, have greater arterial stiffness. view more (2007-06-18)
Physicists and engineers search for new dimension
The universe as we currently know it is made up of three dimensions of space and one of time, but researchers in the Department of Physics and the Department of Electrical and Computer Engineering at Virginia Tech are exploring the possibility of an extra dimension. view more (2008-03-11)
Breast Tumors in Mice Eradicated Using Cancer Vaccine
A team from the University of Pennsylvania School of Medicine has shown that by using a cancer vaccine based on the bacterium Listeria monocytogenes, they can cure mice with established breast tumors. view more (2005-09-15)
High arterial pulse pressure associated with high-tension open-angle glaucoma
Individuals with a high pulse pressure (the difference between the systolic [top number] and diastolic [bottom number] blood pressure), appear to have an increased risk for high-tension open-angle glaucoma. view more (2007-06-12)
Can Eurofighter's radar win UK's biggest engineering prize?
BAE Systems Avionics Group, based in Edinburgh, has been shortlisted for this year's £50,000 Royal Academy of Engineering MacRobert Award, the UK's most coveted prize for engineering innovation, for the world's first airborne radar that can see all the targets all the time. The unique ECR-90 microwave radar was developed specially for... view more... (2000-07-03)
Children's Hospital scientists identify possible target for prevention and treatment of pneumonia
Researchers at Children's Hospital of Pittsburgh of UPMC have identified a key protein target that may be a crucial factor in the development of a vaccine to prevent and new therapies to treat pneumonia, the leading killer of children worldwide. view more (2008-02-12)
New vaccine protects more effectively against tuberculosis
Globally, tuberculosis remains the number one killer in adults. Moreover, multi-drug-resistant tuberculosis strains are on the rise which cannot be treated by first-line drugs. view more (2005-08-29)
Researchers confirm role of massive flood in climate change
Climate modelers at the Goddard Institute for Space Studies (GISS) have succeeded in reproducing the climate changes caused by a massive freshwater pulse into the North Atlantic that occurred at the beginning of the current warm period 8,000 years ago. view more (2006-01-10)
Lighter gas reduces damage to optics in extreme ultraviolet lithography
Researchers at the University of Illinois have discovered a way to generate light and reduce damage in a leading candidate for next-generation microelectronics lithography. The technique could help pack more power into smaller computer chips. view more (2007-09-13)
Natural born killers -- how the body's frontline immune cells decide which cells to destroy
The mechanism used by 'Natural Killer' immune cells in the human body to distinguish between diseased cells, which they are meant to destroy, and normal cells, which they are meant to leave alone, is revealed in new detail in research. view more (2009-07-28)
New technologies enhance quantum cryptography
A team of Los Alamos National Laboratory scientists, in collaboration with researchers from the National Institute of Standards and Technology in Boulder, Colo., and Albion College, in Albion, Mich., have achieved quantum key distribution (QKD) at telecommunications industry wavelengths in a 50-kilometer (31 mile) optical fiber. view more (2006-02-03)
Shape Matters: NC State Scientists Characterize Structure of Protein Involved in Preventing Alzheimer's, Huntington's Diseases
Scientists at North Carolina State University have effectively lifted the veil from an important protein that is linked to the prevention of neurodegenerative diseases like Alzheimer's and Huntington's. view more (2006-07-26)
Depression: New therapy gives reason for hope
A study at the University Clinics of Bonn and Cologne gives people with therapy-resistant depression reason for hope. The doctors treated two men and a woman with what is known as deep brain stimulation. view more (2007-04-19)
Immunologists find better way to boost the immune system
Immunologists have discovered how to manipulate the immune system to increase its power and protect the body from successive viral infections. view more (2008-01-23)
