Blocking the spread of antibiotic resistance in bacteria
It's as simple as A, T, G, C. Northwestern University scientists have exploited the Watson-Crick base pairing of DNA to provide a defensive tool that could be used to fight the spread of antibiotic resistance in bacteria -- one of the world's most pressing public health problems.   view more (2008-12-19)

Scientists Present 'Moving' Theory Behind Bacterial Decision-Making
Biochemists at North Carolina State University have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to function, a finding that could provide a new target for drugs to disrupt bacterial decision-making processes and related diseases.   view more (2008-11-25)

Scripps research scientists identify blood component that turns bacteria virulent
Scientists from the Scripps Research Institute have discovered the key chemical that signals Bacillus anthracis, the bacterium that causes anthrax, to become lethal. This finding opens up new avenues of exploration for the development of treatments for bacterial infections.   view more (2008-11-24)

Nature study demonstrates that bacterial clotting depends on clustering
Bacteria can directly cause human blood and plasma to clot-a process that was previously thought to have been lost during the course of vertebrate evolution, according to new research at the University of Chicago, National Institute of Allergy and Infectious Diseases, and Institut Pasteur in Paris.... view more (2008-11-03)

UCLA develops safer, more effective TB vaccine for HIV-positive people
UCLA scientists engineered a new tuberculosis (TB) vaccine specifically designed for HIV-positive people that was shown to be safer and more potent than the current TB vaccine in preclinical trials.   view more (2008-10-24)

Green catalysts provide promise for cleaning toxins and pollutants
Tetra-Amido Macrocyclic Ligands (TAMLs) are environmentally friendly catalysts with a host of applications for reducing and cleaning up pollutants, and a prime example of "green chemistry." Carnegie Mellon University's Terry Collins, the catalyst's inventor, believes that the... view more (2008-08-18)

Francisella tularensis: Stopping a biological weapon
Scientists hope a vaccine is on the horizon for tularemia, a fatal disease caused by the pathogen Francisella tularensis, an organism of concern as a potential biological warfare agent. Until recently we knew very little about this bacterium.   view more (2008-07-28)

Effective health messages may yield vaccine compliance among ER workers
Emergency room workers will be the first line of defense in the event of a disease pandemic and will be forced to deal with the chaos that inevitably comes with treating thousands of sick and dying. In order to protect themselves and allow them to care for the public, these first responders need to... view more (2008-06-18)

New strategies against bird flu
The Spanish flu outbreak of 1918 killed between 30 and 50 million people. In the infected patients, the ultimate cause of death was acute respiratory distress syndrome (ARDS).   view more (2008-04-18)

NIST, Army researchers pave the way for anthrax spore standards
Researchers from the National Institute of Standards and Technology (NIST) and the U.S. Army Dugway (Utah) Proving Ground have developed reliable methods based on DNA analysis to assess the concentration and viability of anthrax spores after prolonged storage.   view more (2008-04-16)

Protein data bank archives 50,000th molecule structure
The Protein Data Bank (PDB) based at Rutgers, The State University of New Jersey, and the University of California-San Diego (UCSD) this month reached a significant milestone in its 37-year history. The 50,000th molecule structure was released into its archive, joining other structures vital to... view more (2008-04-09)

Is a cup of tea really the answer to everything -- even anthrax?
A cup of black tea could be the next line of defence in the threat of bio-terrorism according to new international research.   view more (2008-03-13)

How do infections and toxins launch a cell's self-destruct and alarm system?
Cells are coded with several programs for self-destruction. Many cells die peacefully. Others cause a ruckus on their way out.   view more (2008-03-11)

Researchers find possible target to treat deadly bloodstream infections
Researchers at the University of Illinois at Chicago have discovered a possible target to treat bloodstream bacterial infections.   view more (2008-02-29)

'Smart' holograms help patients help themselves
Patients with diabetes, cardiac problems, kidney disorders or high blood pressure could benefit from the development of new hologram technology.   view more (2008-02-04)

Team IDs weakness in anthrax bacteria
MIT and New York University researchers have identified a weakness in the defenses of the anthrax bacterium that could be exploited to produce new antibiotics.   view more (2008-01-25)

Using carbon nanotubes to seek and destroy anthrax toxin and other harmful proteins
Researchers at Rensselaer Polytechnic Institute have developed a new way to seek out specific proteins, including dangerous proteins such as anthrax toxin, and render them harmless using nothing but light.   view more (2007-12-11)

Northwestern exposing most deadly infectious diseases in 3-D
A scientist slides on a pair of plastic 3-D glasses and an unearthly blue multi-armed creature -- an image right out of a sci-fi horror flick -- seems to leap out of the computer screen into the laboratory.   view more (2007-11-01)

Scripps research scientists develop innovative dual action anthrax vaccine-antitoxin combination
The immune response generated in rats by the new agent protects against lethal toxin exposure after only one injection, and is faster and stronger than any currently available vaccine.   view more (2007-10-05)

Toxic shock: immune system's anthrax link
Human immune proteins crucial for fighting cancer, viruses and bacterial infections belong to an ancient and lethal toxin family previously only found in bacteria, Australian researchers have found.   view more (2007-08-24)

Clemson scientists shed light on molecules in living cells
Clemson University chemists have developed a method to dramatically improve the longevity of fluorescent nanoparticles that may someday help researchers track the motion of a single molecule as it travels through a living cell.   view more (2007-08-21)

Computers help chemists fight emerging infections
Computer analysis of existing drugs may be key to fighting new infectious agents and antibiotic-resistant pathogens like deadly tuberculosis strains and staph 'superbugs.'   view more (2007-08-20)

Anthrax vaccine produces immunity with nanoparticles, not needles
A vaccine against anthrax that is more effective and easier to administer than the present vaccine has proved highly effective in tests in mice and guinea pigs, report University of Michigan Medical School scientists in the August issue of Infection and Immunity.   view more (2007-08-17)

Anthrax bacterium's deadly secrets probed
New insights into why the bug that causes anthrax behaves in the unusual way that it does have come to light thanks to a development under the UK e-Science Programme.   view more (2007-08-07)
