One of the world's great poisoning mysteries may have been solved – the source of the arsenic that turns up in lethal quantities in hundreds of thousands of wells across Bangladesh. The answer is ponds.
Bangladesh occupies the flood-prone delta of the river Ganges. In the past half-century, v... Read More
An addendum to the earlier article "Scientists Guide Immune Cells with Light and Microparticles," this is a video of an immune cell following the allur... Read More
A team led by Yale University scientists has developed a new approach to studying how immune cells chase down bacteria in our bodies. Their findings are described in the November 15 issue of Nature Methods Advanced Online Publication.
When bacteria enter our bodies they secrete molecules, lea... Read More
Bacteria which glow green in the presence of explosives could provide a cheap and safe way to find hidden landmines, Edinburgh scientists claim. The bugs can be mixed into a colourless solution, which forms green patches when sprayed onto ground where mines are buried.
Edinburgh University sa... Read More
An experiment by college students that will study how microbes grow in microgravity is heading to orbit aboard space shuttle Atlantis.
Undergraduate and graduate students at Texas Southern University in Houston developed the experiment that will fly as part of the STS-129 mission. The mission... Read More

The Gainsville Sun is reporting that opposition has put a stop for now to a federal proposal that would have halted the sale of raw oysters from the Gulf of Mexico unless they were treated for a potentially deadly bacteria.
The Food and Drug Administration announced last month that effective ... Read More
Structural biologists at the University of Pittsburgh School of Medicine have described the architecture of the complex of protein units that make up the coat surrounding the HIV genome and identified in it a "seam" of functional importance that previously went unrecognized.

Stinking lagoons of pig poo created by thousands of animals in giant pig farms can pollute rivers, poison groundwater and pump out clouds of methane and carbon dioxide. Using microorganisms to break down slurry makes sense for two reasons. The first is environmental protection, but the methane p... Read More
A new study is linking cumulative exposure to five common pathogens with an increased risk for stroke. The infections in order of significance are Chlamydia pneumoniae, Helicobacter pylori, cytomegalovirus and herpes simplex viruses 1 and 2. Read More
The AIDS virus inserts its genetic material into the genome of the infected cell. Scientists of the German Cancer Research Center have now shown for the first time that the virus almost entirely spares particular sites in the human genetic material in this process. This finding may be useful for... Read More
In an advance that could help ease health and environmental concerns about the emerging nanotechnology industry, scientists are reporting development of technology for changing the behavior of nanoparticles in municipal sewage treatment plants -- their main gateway into the environment. Their st... Read More
Vincent and Dick provide an overview of parasites and parasitism.
A new form of biodegradable shipping material by a company called Ecovative is created by filling a reusable mold with agricultural waste like rice husks and is then sprayed with mushroom root cells. The cells eat the husks and grow to form a dense network that packs the mold. After baking, the ... Read More
Luciano Marabese, an Italian inventor has combined his Catholic faith and ingenuity to create the electronic terracotta holy water dispenser. It functions like an automatic soap dispenser in public lavatories - a churchgoer waves his or her hand under a sensor and the machine spurts out holy wat... Read More
Prodesse’s molecular diagnostic test for H1N1 swine flu infections has been cleared by EU regulators for commercialization in Europe.
The firm, which recently became a subsidiary of Gen-Probe, received the CE Mark clearance for its ProFlu-ST assay as a diagnostic to differentiate among influe... Read More
Government health officials say swine flu has sickened about 22 million Americans since April.
They say about 4,000 have died, including 540 children.
The startling new figures — about four times higher than previous death estimates — don’t mean swine flu has suddenly gotten worse. Instead... Read More
A virus that causes the common cold may be saving people from swine flu. If this intriguing idea turns out to be true, it would explain why swine flu's autumn wave has been slow to take off in some countries and point to new ways to fight flu.
"It is really surprising that there has not been ... Read More
"In an effort to stem a massive bee die-off, government scientists have developed a population of honeybees that can root out a main culprit in the epidemic -- a parasite that feeds on pupae in nests and spreads viruses within hives.
U.S. Department of Agriculture (USDA) scientists hope the p... Read More
