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

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

Medical researchers use laboratory-grown human cells to learn the intricacies of how cells work and test theories about the causes and treatment of diseases. The cell lines they need are “immortal”—they can grow indefinitely, be frozen for decades, divided into different batches and shared among... Read More

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

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

At least 50 per cent of antibiotic use in hospitals is inappropriate, according to a new report from the national Health Protection Surveillance Centre (HPSC) which yesterday published guidelines on proper antimicrobial stewardship in hospitals in Ireland.

The report warns that in addition to... Read More

In the latest analysis of packaged leafy greens, Consumer Reports found that nearly 40 percent of samples tested contained bacteria consistent with poor sanitation and fecal contamination.

Leafy greens have been under particular scrutiny since late 2009, when the Center for Science in the Pu... Read More

Wine lovers will delight in this guest blog post on Small Things Considered and adaptation from an article in the January 2010 issue of Wines and Vines by John Ingraham, a retired UC Davis Professor of Microbiology, on how he and his colleagues tamed the "capricious and independent" cycle of mal...

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

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

A common plant virus lures aphids to infected plants by making the plants more attractive, but when the insects taste the plant, they quickly leave for tastier, healthier ones. In the process, the insects rapidly transmit the disease, according to Penn State entomologists.

"The virus improves... 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

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

In the age-old battle between man and microbe, people have tried in countless ways to keep their surroundings germ-free, ranging from plain old scrubbing, heat sterilization and chemical disinfectants to high-tech solutions like irradiation or drug-eluting coatings.

Now a new approach could m... Read More

Researchers at Uppsala University and the Swedish University of Agricultural Sciences (SLU) have found several genes that lead to increased risk for an SLE-like autoimmune disorder in dogs. This is the first time scientists have found genes behind such a complex disease.

The study is being pu... Read More
