Tracking membranes of rupturing blood cells sheds light on malaria infection
By specially tagging the outer and inner membranes of red blood cells infected with the malaria parasite and tracking the cellular changes that precede the cell bursting event that disperses parasites to other blood cells, a group of researchers has deepened our understanding of how the malaria... view more (2005-09-22)

Pitt researchers see electron waves in motion for first time
Both the ancient art of stained glass and the cutting-edge field of plasmonics rely on the oscillation of electrons in nanosized metal particles. When light shines on such particles, it excites the electromagnetic fields on the metal's surface, known as "surface plasmons," and causes its... view more (2005-06-10)

NIST develops rapid method for judging nanotube purity
Researchers at the National Institute of Standards and Technology (NIST) have developed a sensitive new method for rapidly assessing the quality of carbon nanotubes.   view more (2007-02-02)

Researchers visualize complex pigment mixtures in living cells
In a technical advance that could allow researchers to watch cells as they act during the process of photosynthesis, scientists have developed a method that extends the power of fluorescence-mediated bio-imaging to see discrete pigments inside live cells of bacteria.   view more (2008-03-05)

Viral hitchhiker inhibits Wolbachia bacteria's ability to proliferate
Scientists studying the widespread symbiotic bacteria Wolbachia have long been interested in its ability to proliferate.   view more (2006-05-19)

On the cutting edge: Carbon nanotube cutlery
Researchers at the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder (CU) have designed a carbon nanotube knife that, in theory, would work like a tight-wire cheese slicer.   view more (2006-11-27)

Nanoscale Tubing Assembles Itself Instantly
Making tubes useful often means joining them to other tubes and linking them together in networks. Easy enough to do with standard water pipes - but on the nanoscale, joining nanotubes is hard to do.   view more (2006-02-28)

Using Life's Building Blocks to Control Nanoparticle Assembly
Using DNA, the molecule that carries life's genetic instructions, researchers at the U.S. Department of Energy's Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters.   view more (2007-08-23)

Leishmaniasis parasites evade death by exploiting the immune response to sand fly bites
Cutaneous leishmaniasis, a disease characterized by painful skin ulcers, occurs when the parasite Leishmania major, or a related species, is transmitted to a mammalian host by the bite of an infected sand fly.   view more (2008-08-15)

Scientists learn structure of enzyme in unusual virus
Biologists have determined the three-dimensional structure of an unusual viral enzyme that is required in the assembly of new viruses.   view more (2007-09-18)

Viruses hitch a ride in the cell
Viruses can travel around cells they infect by hitching a ride on a microscopic transport system, according to new research. Cells are exposed to foreign DNA and RNA and it is understood that some of this genetic material can be integrated into the host genome. Using modern microscopic techniques,... view more (2008-06-24)

Boston University scientists develop new application to characterize structure of DNA molecules
A team of researchers from Boston University has developed a new application to enable more precise measurement of the location of a fluorescent label in a DNA layer.   view more (2006-03-01)

NIST and partners identify tiny gold clusters as top-notch catalysts
For most of us, gold is only valuable if we possess it in large-sized pieces. However, the "bigger is better" rule isn't the case for those interested in exploiting gold's exceptional ability to catalyze a wide variety of chemical reactions, including the oxidation of poisonous carbon... view more (2008-09-08)

Researchers map spread of pathogens in the human body
Researchers at the University of Cambridge have discovered a new, more accurate, method of mapping how bacteria spread within the body, a breakthrough that could lead to more effective treatments and prevention of certain bacterial infections.   view more (2006-10-23)

Several tons of uranium and a town called Colonie
Recent research by the Department of Geology at University of Leicester, and at the British Geological Survey aims to improve understanding of how depleted uranium particulate behaves in the environment.   view more (2007-06-27)

University of Sydney researchers find new evidence linking kava to liver damage
In recent years, serious concerns about the dangers of kava and the effects on the liver have resulted in regulatory agencies, such as the US Food and Drug Administration and Australia's Therapeutic Goods Administration, banning or restricting the sale of kava and kava products.   view more (2008-02-25)

Certain combination therapy found more effective for treating malaria in African children
Ugandan children who received the combination therapy of artemether-lumefantrine experienced a lower rate of treatment failure compared to other combination therapies, according to a study in the May 23/30 issue of JAMA, a theme issue on malaria.   view more (2007-05-23)

Pathways of emotion - from cortex to peripheral organs
Walking down a dark alley late at night is enough to give anyone the heebie-jeebies. Your heart starts racing, your palms get clammy and you get ready to run. Now researchers from Boston University have unravelled the neural pathways that transmit information about your surroundings to your organs,... view more (2003-10-07)

Common aquatic animals show extreme resistance to radiation
Scientists at Harvard University have found that a common class of freshwater invertebrate animals called bdelloid rotifers are extraordinarily resistant to ionizing radiation, surviving and continuing to reproduce after doses of gamma radiation much greater than that tolerated by any other animal... view more (2008-03-26)

CSHL scientists successfully target tumor microenvironment to stop cancer growth
Cold Spring Harbor Laboratory (CSHL) researchers led by Daniel Nolan and Assistant Professor Vivek Mittal have found that bone marrow (BM) derived endothelial progenitor cells (EPCs) play a critical role in the early stages of tumor progression and that eliminating EPCs stops cancer growth.   view more (2007-06-18)

Cerium oxide nanotubes get noticed
Chemists and materials scientists often study "nanotubes" - capsule-shaped molecules only a few billionths of a meter (nanometers) in width.   view more (2006-03-29)

Scientists describe new way to peer inside bacteria
As part of the search for better ways to track and clean up soil contaminants, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University have developed a new way to "image" the internal chemistry of bacteria.   view more (2005-08-30)
