Life's Most Amazing Invisible Secrets

One of my heroes, evolutionary microbiologist Lynn Margulis, died this past Thanksgiving. She was an amazing lady who was married to Carl Sagan for many years, and partnered with James Lovelock in discovering that the earth is an interconnected living global ecosystem run largely by microbes. Sh... Read More

As a biological weapon, H5N1 is for the birds (Opinion)

Reuters columnist Peter Christian Hall believes the possibility that H5N1 could be effectively weaponized is remote and there is more harm than good in withholding data from two research papers that outline the methods to create an aerosolized strain of avian flu in ferrets.

"Amid the furor ... Read More

Sheets of virus generate electricity when squished

Squishing a stack of virus sheets generates enough electricity to power a small liquid crystal display. With increased power output, these virus films might one day use the beating of your heart to power a pacemaker, the researchers behind them say.

Piezoelectric materials build up charge whe... Read More

In First, Software Emulates Lifespan of Entire Organism

Scientists at Stanford University and the J. Craig Venter Institute have developed the first software simulation of an entire organism, a humble single-cell bacterium that lives in the human genital and respiratory tracts.

The scientists and other experts said the work was a giant step toward... Read More

Engineering Life to Survive on Mars and Aid Human Colonization

With NASA’s Curiosity Rover safely on Mars and ready to search for signs of life, back on Earth attempts are underway to engineer bacteria that could thrive on the Red Planet.

A team of undergraduates from Stanford and Brown Universities are busy applying synthetic biology to space exploratio... Read More

Friendly Fungi: Elucidating the fungal biosynthesis of stipitatic acid

In a tale worthy of Sherlock Holmes, scientists in the School of Chemistry at the University of Bristol, UK have solved a biochemical mystery that had previously proven elusive for 70 years: How the fungus Talaromyces stipitatus produces stipitatic acid (6), which is a tropolone, one of an atypi...

Leftover Turkey to the Fridge, Stat

As we enjoy our most food-oriented holiday tomorrow, nutritionists and food safety experts recommend that particular care be taken to ensure that leftovers -- whether kept for later meals or dispatched home with guests -- don't become a catalyst for the pain, vomiting, and diarrhea that afflicts...

The Rise of Genomic Superspreaders

One hundred million years ago the earth’s climate was much warmer than today and vast inland seas stretched across entire continents. The land was dominated by charismatic megafauna that would one day serve as inspiration for Sir Arthur Conan Doyle’s novel The Lost World. This period is commonly... Read More

Fungi And Bacteria Help Each Other Stay Mobile

Bacteria and fungi are remarkably mobile. Now researchers at Tel Aviv University have discovered that the two organisms enjoy a mutually beneficial relationship to aid them in that movement - and their survival.

Fungal spores can attach themselves to bacteria, "hitching a ride" wherever the ... Read More

Building the perfect bug

This past February I was interviewed by the Australian Broadcasting Company on the topic of the Fouchier and Kawaoka experiments on avian influenza virus H5N1. The video, Building the Perfect Bug, has been released by Journeyman Pictures and includes interviews with S.T. Lai, Laurie Garrett, Mic... Read More

Replication of immunodeficiency virus in humans

The acquired immunodeficiency syndrome (AIDS) pandemic is caused by the human immunodeficiency virus (HIV-1), which attacks the immune system and leaves infected individuals susceptible to opportunistic infections. AIDS and HIV-1 are thought to have a relatively short history in humans, with the... Read More

Yankee ‘invaders’ threaten UK’s crayfish

Better resistance to parasites and a less fussy diet are allowing aggressive signal crayfish from the US to threaten white-clawed crayfish native to Yorkshire.

The Yorkshire crayfish suffers from two parasites: plague, which is carried by the American invader, and porcelain disease that makes... Read More

What Happened to Our Friendly Enterococci?

Enterococci had been generally regarded as benign commensals, a part of our healthy intestinal microbiota. They were even invited in, being used as probiotics. But then, in the late 1970s, the first multiple drug-resistant strains appeared, and vancomycin-resistant strains followed in 1981. In r... Read More

London prepares for Olympian disease-monitoring task

As the world’s athletes limber up for the forthcoming Olympic games in London, infectious-disease experts are preparing for their own trials. Their competition is with the diseases that millions of athletes, officials, media and spectators bring with them as they converge from across the globe o... Read More

New bug eats sulfates, makes two kinds of magnet

A bacterium recently discovered near Death Valley has some very unusual properties according to a report published in the December 23 issue of Science magazine. While some ‘bugs’ are like migratory birds, making tiny magnets that they use to guide their navigation, this is the first bacterium to... Read More

Bacteria that could pass as X-men: part 1

Great article from Scientific American... click 'source' to see the whole piece...

1) The Blob

Like many of the X-men, the Blob has gone through several incarnations of character but the one main continuous feature is that he’s big. That’s pretty much it. The size gives him supernatural s... Read More

Controversial 'bird flu' edits move ahead

Top US scientists on Wednesday defended their bid to stop details of a mutant bird flu virus from being published and called for global cooperation to ward off an uncontrollable pandemic.

Meanwhile, scientists involved in the experiments said they are cooperating with government officials and... Read More

Study Shows First N.C. Case of Feral Pig Exposure to Nasty Bacteria

A North Carolina State University study shows that, for the first time since testing began several years ago, feral pigs in North Carolina have tested positive for Brucella suis, an important and harmful bacteria that can be transmitted to people.

The bacteria are transmitted to humans by uns... Read More

Bacteria that could pass as X-men: part 2

'Second part of my thinly veiled excuse to research X-men and call it work. The first post can be found here. This is only meant to be a two-parter but I’ll see how I feel on Monday, and whether I can find any more X-men that are as amazing as bacteria.'
