There's a tight and surprising link between the ocean's health and ours, says marine biologist Stephen Palumbi. He shows how toxins at the bottom of the ocean food chain find their way into our bodies, with a shocking story of toxic contamination from a Japanese fish market. His work points a way forward for saving the oceans' health -- and humanity's.

Seth Berkley explains how smart advances in vaccine design, production and distribution are bringing us closer than ever to eliminating a host of global threats -- from AIDS to malaria to flu pandemics.

I've been telling you about the perils of plastics, but some of the worst plastics offenders are molecular and cell biologists. Nearly every experiment that we do uses incredible amounts of plastics. In cell biology or molecular biology labs the emphasis is on working sterile, quickly and reproducibly. So companies have been selling all these incredibly useful products to life science labs: sterile plastic tubes of all shapes and sizes, single wrap multi-well tissue culture plates, sterile plastic dishes, sterile pipettes. All these products make it a lot easier to do the required work. I can't even imagine how you could work in a cell culture lab without them, but they do create a lot of waste.
My friend, Eva Amsen, made this video as a creative outlet and to try and raise some awareness of all the disposables in the lab, and give some mild suggestions on how to reduce the pile of trash by a tiny amount. Every bit helps, right?
This is an overview of the NYAS symposium about Influenza A/H1N1 "swine flu" outbreak that I was invited to attend on 28 May 2009 in NYC.

Recorded in 2007, as the world worried about a possible avian flu epidemic, Laurie Garrett, author of "The Coming Plague," gave this powerful talk to a small TED University audience. Her insights from past pandemics are suddenly more relevant than ever. [21:05]

This video discusses the process of antigen shift in influenza viruses, such as the H1N1 "swine flu" that has recently been identified in Mexico and in quite a few other countries, including in NYC [1:18]

Below the fold is an utterly fascinating video that documents the current state of the research in one lab that is developing a drug that stops foot and mouth disease virus from replicating in the host cells. Even better, this beautfully executed video was created by the lab members themselves! I can hardly wait for more scientists and labs to document their research in real-people accessible videos such as these [6:03]
Now here's an astonishing discovery that's hot off the presses: a virus that infects other viruses! This amazing finding is being published tomorrow in the top-tier peer-reviewed journal, Nature.
I just learned that a lawsuit was recently filed in Massachusetts Superior Court on behalf of a man who died one month after receiving a transplanted liver that was later determined to be infected with lymphocytic choriomeningitis virus (LCMV). Apparently, the organ donor purchased a pet hamster from a PetSmart in Warwick, Rhode Island, and this hamster was later shown to be infected with this deadly virus.
Portrait of an Egyptian Rousette or Egyptian fruit bat, Rousettus aegyptiacus.
Like something out of a sci-fi novel, a man from Uganda died a horrible, bloody death from Marburg hemorrhagic fever this past July. As a result, scientists from the USA and the African nation of Gabon raced to the area to search for the source of this disease, and they may have finally discovered it. The team tested more than 1,000 bats that were captured in caves in Gabon and DR Congo, and discovered that some individuals of one species were infected with Marburg virus. The suspect bat, pictured above, is the Egyptian Rousette or Egyptian fruit bat, Rousettus aegyptiacus.
