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.

This is yet another Lego animation. This time, instead of recreating highlights of the World Cup 2010 games, this one shows highlights for the history of the field of microbiology. It's actually good enough to show as an intro to a microbiology course.
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?

Too much of the world lacks access to clean drinking water. In this video, engineer Michael Pritchard did something about it -- inventing the portable Lifesaver filter, which can make the most revolting water drinkable in seconds. An amazing demo from TEDGlobal 2009. [10:05]

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]

This interesting video is a TEDTalk. TED -- for Technology, Entertainment, Design -- talks cover these topics as well as science, business, development and the arts. They are a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give "the talk of their lives" in 18 minutes. In this TEDTalk, Bonnie Bassler discovered that bacteria "talk" to each other, using a chemical language that lets them coordinate defense and mount attacks. The find has stunning implications for medicine, industry -- and our understanding of ourselves. [18:59]

According to a recently published press release, three new species of bacteria have been discovered in the upper stratosphere by Indian scientists in an experiment conducted by the Indian Space Research Organization (ISRO). This discovery lends some credence to the hypothesis that life might have originated elsewhere in the cosmos and was seeded on Earth after colliding with a foreign body, perhaps a comet or asteroid, that was carrying these ancient organisms. This is one of the basic tenents upon which the new scientific field, astrobiology, is based. However, if you think astrobiology is rubbish, this finding is nonetheless fascinating because it reveals that scientists are still learning the parameters of where life is possible.
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.
