Attach self-propelling bacteria to a cog and they'll set it spinning for you, say Italian physicists.
Last year, we looked at an idea for a bacteria-powered motor dreamt up by Luca Angelani and pals from the University of Rome in Italy. Their idea was to place a cog with asymmetric teeth into... Read More

Whatever you may think of our addiction to fossil fuels, there is no shortage of ideas on how to extract every last tonne. Field trials are now showing that all it takes is common fertiliser.
Natural gas is often present in coalfields, clinging to the coal. It is extracted through wells drill... Read More
This two-minute video is an update from Reuters on the current shortage of H1N1 vaccines. while short, the video does provide some interesting visuals of the production of H1N1 vaccine, as well as the reasons behind the delay. Read More
The UK starts vaccinating people against swine flu today; in the US and Australia, vaccination has already begun. Can we be sure that safety hasn't been compromised in the race to test and produce the vaccine? Didn't vaccination hurt people during the last big swine flu scare? And do the benefit... Read More
Tomatoes, corn, insect resistance in poplar trees, and switchgrass durability through climate change are just some of the focus areas of the $101.6 million that the National Science Foundation has granted this week for plant genome sequencing projects.
Ranging broadly from $500,000 to $10.4 m... Read More
Roche last week said that demand for influenza testing products drove a 24 percent spike in sales for its PCR and nucleic acid purification business in the first nine months of 2009.
Specifically, the company said that sales of its MagNA Pure nucleic acid sample-prep system and its LightCycle... Read More
An international team of researchers from the United States, Korea, and France has sequenced and analyzed the genomes of two important laboratory strains of E. coli bacteria, one used to study evolution and the other to produce proteins for basic research or practical applications. The findings ... Read More
Every year beaches and lakes all over the country as closed down when levels of fecal coliform bacteria levels reach or exceed certain levels. Only when high E. coli levels close truly popular recreational waters is there much attention paid.

In 1843, the Hungarian scientist David Gruby—considered the founder of medical microbiology—was studying a microscopic parasite in frog blood. The parasite seemed to propel itself forward like a corkscrew, so he named the creature Trypanosoma sanguinis, after the Greek word “trypanon,” or augur... Read More
The first HIV vaccine to be called a success has stood up to scrutiny after further analysis of the data was presented today in Paris, France. However, the new analysis also confirms that the optimistic claims, first made in September and viewed sceptically at the time, are indeed very modest.

Twentieth century medicine was phenomenally successful at developing vaccines and antibiotics to fight infectious diseases, taming ancient scourges such as smallpox, tuberculosis and typhoid. In the 1960s and 70s, the prevailing view was that all diseases caused by microorganisms would soon be c... Read More
INTEL's latest microchip technology has created transistors 22 nanometres wide - a mere 200 times the width of a hydrogen molecule. Carving such tiny features is devilishly difficult and expensive, but in another realm of microchips altogether, something odd is happening: chips are being made on... Read More
In a pair of studies appearing online yesterday in Nature Genetics, one group of researchers identified the first systemic lupus erythematosus, or SLE, risk variants in a Chinese population while another group added to the growing list of lupus-associated genes in individuals of European descent...

Babies are often given acetaminophen when they get their routine vaccinations. The drug, sold as Tylenol in the United States and called paracetamol in most countries, counters the common risk of fever and the much less common risk of fevers high enough to cause seizure.
But a new study, don... Read More
The percentage of Salmonella isolates found in ground turkey that displayed resistance to nalidixic acid dropped from 8.1 percent in 2002 to 2.6 percent in 2007. Similarly, the percentage of isolates resistant to ceftiofur dropped from 8.1 percent to 5.3 percent in that period. In contrast, the ... Read More
