Human Excrement to Blame for Coral Decline – ScienceNOW

“Coral reef ecologists have laid a persistent and troubling puzzle to rest. The elkhorn coral, named for its resemblance to elk antlers and known for providing valuable marine habitat, was once the Caribbean’s most abundant reef builder. But the “redwood of the coral forest” has declined 90% over the past decade, in part due to highly contagious white pox disease, which causes large lesions that bare the coral’s white skeleton and kill its tissue. Now, after nearly a decade of data collection and analysis, researchers have fingered the cause of the affliction: human excrement. The finding represents the first example of human-to-invertebrate disease transmission and suggests a practical approach for halting the disease’s spread.”

Really cool detective work. The more I read about microbes and viruses, I see that we’re all really one mass of interconnected organisms, testing out adjacent possibles and inadvertently passing pathogens across species and kingdoms.

And apropos for the two SciFri videos I just posted.

Small Things Considered: Now That’s Using Your Head!

Cool discovery of bactriophage infection that uses a head filament to catch bacterial flagellum. And the motions of the flagellum then draw the virus in and then away to increase chances of infection. Quite cool bit of detective work to reveal years of interesting infection rate data.

Harmful Viruses Made of Beautiful Glass

Beautiful visualizations of viruses and bacteria, made in glass. The artists is exploring what these organisms really look like, since most visualization is in color. Pretty cool.

‘Virus-eater’ discovered in Antarctic lake : Nature News

“A genomic survey of the microbial life in an Antarctic lake has revealed a new virophage — a virus that attacks viruses. The discovery suggests that these life forms are more common, and have a larger role in the environment, than was once thought.”

As usual, tickled pink when Nature finally reveals something that has been in our faces for so long. Always gets me wondering what else we’re missing.

Going Viral: Exploring the Role Of Viruses in Our Bodies

“Many of the viruses prey on the bacteria in our bodies, altering their numbers and diversity and shuffling genes—including genes for antibiotic resistance—from one bacterium to another. At the International Human Microbiome Congress earlier this month, one provocative, albeit preliminary, finding emerged: Infants with unexplained fevers harbor many more viruses than healthy infants.”

Really nice news focus on the balance between the human virome and microbiome and what it means for us humans stuck in the middle. [Alas, the article is behind a subscription - Open Access Fail].
