E. chromi: Designer Bacteria

E. chro­mi, a short film about a unique col­lab­o­ra­tion between design­ers and biol­o­gists has won the best doc­u­men­tary award at Bio:Fiction, the world’s first syn­thet­ic biol­o­gy film fes­ti­val, held ear­li­er this month in Vien­na.
E. chro­mi tells the sto­ry of a project unit­ing design­ers Alexan­dra Daisy Gins­berg and James King with a team of under­grad­u­ate biol­o­gy stu­dents at Cam­bridge Uni­ver­si­ty. Using genes from exist­ing organ­isms, the team designed cus­tom DNA sequences, called Bio­Bricks, and insert­ed them into E. coli bacteria.The new E. coli—dubbed “E. chromi”—were pro­grammed to express a rain­bow of col­ors when exposed to var­i­ous chem­i­cals.

Gins­berg and King helped the young biol­o­gists dream up a vari­ety of pos­si­ble appli­ca­tions for the invention.For exam­ple, E. chro­mi could be used to test the safe­ty of drink­ing water–turning red if a tox­in is present, green if it’s okay. Or it might  be used as an ear­ly warn­ing sys­tem for dis­ease: a per­son would ingest some yogurt con­tain­ing E. chro­mi, then watch out for tell-tale col­ors at the oth­er end of the diges­tive process.

The E. chro­mi team was award­ed the grand prize at the 2009 Inter­na­tion­al Genet­i­cal­ly Engi­neered Machine (iGEM) com­pe­ti­tion at the Mass­a­chu­setts Insti­tute of Tech­nol­o­gy. For more films on syn­thet­ic biol­o­gy, see the Bio:Fiction web­site.

Endeavour’s Launch Viewed from Booster Cameras

Here’s the good stuff that nerdgasms are made of. NASA has released a video that lets you hitch a ride on the May 16th launch of the Space Shut­tle Endeav­our. The video runs 37 min­utes; it’s nar­rat­ed by a NASA offi­cial; and it loops around and lets you see the launch from sev­er­al dif­fer­ent van­tage points.

You start with liftoff, trav­el­ing at 1300 miles per hour. Then, about two min­utes lat­er, the rock­et boost­ers sep­a­rate from the shut­tle, and you then twist with them. The sec­ond loop starts around the 7:20 mark, and don’t miss the splen­did view at 9:40 …

The Climate Scientist Rap (Warning: Offensive Language)

In this high­ly NSFW video pro­duced by the Aus­tralian tele­vi­sion show Hun­gry Beast, a posse of bona fide, degree-hold­ing cli­mate sci­en­tists put the ulti­mate smack­down on cli­mate change deniers. By NSFW, we mean that the rap is “more exple­tive-rid­den than the lat­est Lil’ Wayne sin­gle.” Still, after a few lis­tens we did find a cou­plet clean enough to quote:

We’re scientists/What we speak is true
Unlike Andrew Bolt/Our work is PEER REVIEWED!

If you feel like drop­ping $1.69, you can also buy the extend­ed sin­gle on iTunes.

Richard Dawkins to Publish Children’s Book This Fall

Richard Dawkins, the Oxford evo­lu­tion­ary biol­o­gist, has a new book com­ing out this fall. This time, it’s a chil­dren’s book called The Mag­ic of Real­i­ty: How We Know What’s Real­ly True. Inter­viewed in Der Spiegel in March, Dawkins talked a lit­tle about what he hoped to accom­plish here, say­ing:

Each chap­ter is a ques­tion like: What is an earth­quake? What is a rain­bow? What is the sun? Each chap­ter begins with a series of myths seem­ing­ly answer­ing those ques­tions, and then I counter that with expla­na­tions about the true nature of things. There is some­thing very cheap about mag­ic in the super­nat­ur­al sense, like turn­ing a frog into a prince with a mag­ic wand. Real­i­ty has a grander, poet­ic mag­ic of its own, which I hope I can get across.

Already you can see some pre­lim­i­nary art­work for the book. We have one cov­er design above, and anoth­er one here. We’ll have more on the book when it comes out…

Milky Way Panorama (with a Backstory)


Nick Risinger, an ama­teur astronomer from Seat­tle, quit his day job last year, packed his bags and cam­eras, and began a 60,000 mile jour­ney, mov­ing across the Amer­i­can West and down to the west­ern Cape of South Africa (twice). His voy­age would end with a 5000-megapix­el pho­to­graph of the entire night sky, pro­duced from 37,440 sep­a­rate expo­sures, and it yields a stag­ger­ing 360-degree view of the Milky Way. Even bet­ter, the image now lives online in an inter­ac­tive for­mat, giv­ing you the abil­i­ty to wan­der through the cos­mos.

For more on this, be sure to vis­it Pho­topic Sky Sur­vey. Here Risinger gives you the per­son­al and tech­ni­cal back­sto­ry on his project, and also gives you the chance to pur­chase pho­tos, or even lend finan­cial sup­port to the sky sur­vey.

Fire Ants Create Life Raft in 100 Seconds Flat

The cen­tral intel­li­gence of ants – the way ant colonies orga­nize them­selves with­out a leader and get things done – con­tin­ues to amaze sci­en­tists and sci­ence writ­ers alike. Back in 2003, Deb­o­rah Gor­don, a Stan­ford biol­o­gist, gave a whole TED Talk called “How Do Ants Know What to Do?,” which sheds light on how ants can form stun­ning­ly com­plex, lead­er­less sys­tems. Then, sev­er­al years lat­er, Radi­o­Lab con­tin­ued to mull over Gor­don’s fas­ci­nat­ing research in one of its very first episodes.

Now we get this great bit of video. It comes to us via researchers at the Geor­gia Insti­tute of Tech­nol­o­gy, and it shows how ants, when placed in water, can form a com­plete­ly water­tight raft in under two min­utes. “They’ll gath­er up all the eggs in the colony and will make their way up through the under­ground net­work of tun­nels, and when the flood waters rise above the ground, they’ll link up togeth­er in these mas­sive rafts,” says Nathan J. Mlot, an engi­neer­ing stu­dent involved in the project. Amaz­ing­ly, even the ants at the bot­tom of the raft nev­er get sub­merged. They all sur­vive, which rais­es the ques­tion: Can this research lead to new floata­tion devices for the rest of us to use?

Ray Kurzweil, Futurist: 10 Questions About What’s Coming Next

The 2009 doc­u­men­tary Tran­scen­dent Man: The Life and Ideas of Ray Kurzweil is cur­rent­ly screen­ing both online and in select venues, and pro­vok­ing exact­ly the wide range of respons­es one would expect from a film about a futur­ist who has claimed, among oth­er things, that man would soon learn how to extend his life “indef­i­nite­ly.” The New York Times recent­ly com­pared his the­o­ries with 2nd and 3rd cen­tu­ry gnos­ti­cism, and since this film was made by an avowed believ­er in Kurzweil’s phi­los­o­phy and the­o­ries, it’s no sur­prise that Sci­en­tif­ic Amer­i­can faults the movie for its rev­er­ence, and Vari­ety wish­es “It were not so trans­par­ent­ly on [Kurzweil’s side].”

Mean­while, the “high­ly sophis­ti­cat­ed crack­pot,” as you see him described in the movie’s trail­er, has been proven right more often than wrong. His fans are legion, and often wealthy. Lar­ry Page, the founder and CEO of Google, helped estab­lish Sin­gu­lar­i­ty Uni­ver­si­ty with Kurzweil in 2008, and there many entre­pre­neurs and investors take 10 week cours­es to the tune of $25,000.

If you’re not inter­est­ed in shelling out $5 to rent the movie online (scroll down to the bot­tom of the page), then Kurzweil’s 10 answers to Time Mag­a­zine’s 10 ques­tions will give you a taste of what the fuss has been all about.

The Soundtrack of the Universe

We think of space as a silent movie, some­thing we see but nev­er hear. Yet space cre­ates a sound­track of sorts (even if sound waves can’t real­ly trav­el through the cos­mos), and now sci­en­tists and musi­cians want to play that sound­track for you.

Ear­li­er this year, Jan­na Levin, Pro­fes­sor of Physics and Astron­o­my at Barnard College/Columbia Uni­ver­si­ty, described how we can math­e­mat­i­cal­ly mod­el the sounds made by black holes. Fast for­ward to the 10:27 mark of her TED Talk above, and you will hear what it sounds like when a lighter black hole falls into a heav­ier black hole. The lit­tle guy bangs against space, kind of like a drumb play­ing faster and faster … which brings us to Mick­ey Hart, a for­mer drum­mer for The Grate­ful Dead.

In 2010, Hart teamed up with George Smoot, a Nobel Prize-win­ning physi­cist at the Lawrence Berke­ley Nation­al Lab­o­ra­to­ry, to repro­duce the sound of The Big Bang and super­novas. (Berke­ley Labs post­ed this super­no­va clip above.) You can read more about the unlike­ly pair­ing and the “Rhythms of the Uni­verse” project here, then expe­ri­ence more celes­tial sounds recre­at­ed by Hart here.
