The anticancer drugs, such as DNA replication inhibitors, stimulate bacterial adhesion and induce the bacterial SOS response. As a variety of bacterial mutants can be generated during SOS, novel phenotypes are likely to be selected under the drug pressure.Presentation of the hypothesisBacteria g... Read More
Monash University biochemists have found a critical piece in the evolutionary puzzle that explains how life on Earth evolved millions of centuries ago.
The team, from the School of Biomedical Sciences, has described the process by which bacteria developed into more complex cells and found thi... Read More
Unlike antibiotics, which kill many different types of bacteria, antiviral drugs for the most part need to target individual, specific viruses. A drug that attacks a multitude of viruses -- an antibiotic for viruses, effectively -- would be a significant boon for medicine. And a group of researc... Read More
Researchers at North Carolina State University have developed a "smart coating" that helps surgical implants bond more closely with bone and ward off infection.
When patients have hip, knee or dental replacement surgery, they run the risk of having their bodies reject the implant. But the sma... Read More
Researchers at the University of Copenhagen have become the first in the world to synthesize the entire protein that is responsible for life-threatening malaria in pregnant women and their unborn children. The protein known as VAR2CSA enables malaria parasites to accumulate in the placenta and c... Read More
Australian researchers are scrambling to develop drugs to fight off Acinetobacter baumanii, a new "superbug" that is causing fatalities overseas.
Experts say Acinetobacter is far worse than superbugs such as MRSA, which are already in Australian hospitals.
Australian health authorities sa... Read More
Thomas Cavalier-Smith, Department of Zoology, University of Oxford, has published a paper in which he identifies some of the key elements to understanding eukaryogenesis.
"Here I paint an integrated picture of how the nucleus, sex, and the eukaryotic cell cycle originated and congealed into ... Read More
A new device that sniffs out malodorous bacteria in stool samples may yield the first rapid test for a potentially lethal diarrheal disease spreading across North America and Europe.
The OdoReader can detect the bacterium Clostridium difficile in about 10 minutes with 96 percent accuracy, sai... Read More
Using genetically modified bacteria, a team of Australian researchers has created artificially produced honey bee silk.
"The silks would be good for tough, lightweight textiles, and high-strength applications like advanced aviation and marine composites," ABC Science quoted CSIRO entomologis... Read More
Bacteria that infect chronic wounds can be deadly to maggot 'biosurgeons' used to treat the lesions, show researchers writing in the journal Microbiology. The findings could lead to more effective treatment of wounds and the development of novel antibiotics.
Scientists from the Copenhagen Wou... Read More
The new three-year program from the National Science Foundation and Microsoft announced on Thursday at a news conference in Washington offers scientists the computing power to cope with exploding amounts of research data. It uses Microsoft’s Windows Azure computing system, which the company rece... Read More
President Barack Obama announced on February 3 three actions that the federal government is taking to boost U.S. biofuels production. The measures include: the final rule from the U.S. Environmental Protection Agency (EPA) to implement the Renewable Fuels Standard (RFS) of 36 billion gallons by ... Read More
A study published online on February 1 in the Journal of Experimental Medicine shows that antiviral proteins called type I interferons (IFNs) are needed to fend off infection with an exotic mosquito-borne virus called Chikungunya virus.
This pathogen, which causes high fevers and severe joint... Read More
Pneumonia is by far the leading killer of seniors who contract either seasonal or pandemic H1N1 influenza, but far too many of the elderly are not immunized against it, according to a report issued Thursday by the Infectious Diseases Society of America, the Robert Wood Johnson Foundation and the...

A team of engineers and chemists at Brigham Young University has created a silicon microchip they say can reliably detect specific proteins or viruses from even small samples at low concentrations. Their invention, which is forthcoming in the paper version of the journal Lab on a Chip, work... Read More
Already incorporated into consumer products ranging from baseball bats and clothing to sunscreens and toothpaste, engineered nanoparticles — ENPs — hold great promise in such areas as energy, pollution remediation, medicine and materials science. The nanotechnology industry is projected to be wo... Read More
A simple, low cost method to detect toxins from the organism causing the wasting disease Buruli ulcer has been developed by US scientists.
Buruli ulcer is a wasting disease caused by organisms called Mycobacterium Ulcerans, which are in the same group as the organisms causing leprosy and tub... Read More
Antiviral drugs block influenza A viruses from reproducing and spreading by attaching to a site within a proton channel necessary for the virus to infect healthy cells, according to a research project led by Iowa State University's Mei Hong and published in the Feb. 4 issue of the journal Nature...

Two groups of Howard Hughes Medical Institute (HHMI) scientists working independently have identified a critical enzyme that allows the malaria-causing parasite, Plasmodium falciparum, to take over and thrive in human red blood cells. The enzyme plasmepsin V (PMV) is a gatekeeper inside the ... Read More
In the late summer of 1882, a ship called the Triton cruised the chilly seas north of Scotland. As it went, it dredged the sea bed for specimens of unknown creatures, under the guidance of the oceanographer John Murray.
Two of the specimens were strange enough that Murray sent them to his col... Read More
