The Circle of Life (and how Jellyfish screw it up)

by Holly Bik in Deep Sea News

Mufasa was right.  We’re all intertwined.  Whether we humans like to admit it or not, every action by a living organism on Earth has repercussions.  (And yes, you can lump in viruses and prions because I’m not getting into a philosophical debate about what constitutes ‘living’). Run, Harry! You don't want to catch Irukandji . . . → Read More: The Circle of Life (and how Jellyfish screw it up)... Read more »

Highlights from ISIE 2011

by James Keirstead in James Keirstead.ca

Last week was the biennial conference of the International Society of Industrial Ecology, held at the lovely University of California Berkeley. At four days, plus an extra workshop for the Sustainable Urban Systems section, it was a long event but the week went quickly with a number of excellent talks and interesting attendees. Here are some of my highlights.... Read more »

Computers and Electrifying Bacteria

by Paige Brown in From The Lab Bench

Computer-based simulations that use an organism's hereditary information are revealing previously unknown but essential life functions of special bacteria that can be modified to help clean our water and produce electricity for our alternative energy needs... Read more »

New data about Amazonian Dark Earth (ADE).

by Umberto in Up and Down in Moxos

The Journal of Archaeological Science has just published a new study on ADE. The study, of Birk et al. is entitled: “Faeces deposition on Amazonian Anthrosols as assessed from 5b-stanols”. I have just read it and this is my very first impression:The new data are extremely interesting. The authors look at the presence of coprostanol (a marker for faeces) in Amazonian Dark Earth (ADE). They have found a clear change in the index used to asses different sources of stanols, when comparing sample........ Read more »

McInnis Canyons Mygatt-Moore Quarry Gives Up Fossil Clues

From the Archives: Reflections on the Gulf Oil Spill - Conversations With My Grandpa

by Christie Wilcox in Observations of a Nerd

If you didn't already know because, by chance, you missed my tweets, posts, and facebook updates, there is a science blogging contest going on RIGHT NOW. The 3 Quarks Daily Science Blogging Prize is currently narrowing down the top 20 posts from 87 nominees. To get through the gauntlet, a post has to get enough votes. Rather than remind you again to vote for Observations of a Nerd, I figured I'd show you why you should. Over the next 24 hours, I'll be reposting the three posts in the competition........

Revenge of the Meat-Eating Megatherium

by Laelaps in Laelaps

Unknown Island has to be one of the crummiest dinosaur movies ever made. Though it came out about 15 years after King Kong debuted, the plot is broadly the same and executed with less skill – young filmmaker hires a crew to go to an island swarming with prehistoric life; mayhem ensues. The acting’s bad, [...]... Read more »

Earliest human migrations

by zacharoo in Lawn Chair Anthropology

One of my favorite paleoanthropological sites is Dmanisi, in the Republic of Georgia. It is the oldest securely dated hominid site outside Africa (just under 1.85 million years ago), and the hominids found there display a neat mix of primitive Homo habilis and derived H. erectus features. I consider myself lucky to have had the opportunity to excavate at Dmanisi last year, and to return to Georgia (lamazi Sakartvelo! [I hope I translated that correctly]) for more fieldwork next month.
Recently, ........ Read more »

Plesiosaurs, the Beautiful Bottom-Feeders

by Laelaps in Laelaps


In 1821, British geologists Henry De la Beche and William Conybeare presented a bizarre, previously-unknown fossil creature to their colleagues in the Geological Society of London. They called their monster Plesiosaurus. A paddle-legged marine reptile akin to the recently-discovered, shark-shaped animals known as ichthyosaurs, the new animal was cast as “a link between the Ichthyosaurus [...]... Read more »

A Plethora of Fossil Possums

by Laelaps in Laelaps

In many technical papers describing fossil creatures, artists give readers a glimpse of prehistory through reconstructions of what those animals might have looked like in life. Not so with Pucadelphys andinus. In a paper published this week in Nature, artist S. Fernandez depicted a pair of the possum-like creatures at a critical point in their [...]... Read more »

Countdown to extinction!

One of my favorite Megadeth albums and songs, although that’s for another time.  The title also fits for a handful of species from a  group particularly close to my heart – seagrasses.  Seagrasses made the news recently, as a recent report suggest as many as 10 of the 72 known seagrass species are at risk of . . . → Read More: Countdown to extinction!...

After canals go in, fish diversity goes up… many millenia from now

by Maria José Viñas in GeoSpace

Facing a growing population and increasing demands for fresh water, India is hoping that an engineering fix will help solve its water-scarcity problems. The country’s National Water Development Agency has begun work on the first of a system of 30 canals that would link 46 rivers, in a process known as inter-basin water transfer.... Read more »

Stressed Lemurs and Grass-Eating Humans

by Laelaps in Laelaps

In his 1960 presidential address to the South African Archaeological Society, the anthropologist Louis Leakey cast the fossil humans that had been found in that country as little more than a collection of evolutionary dead-ends. Leakey didn’t put it quite like that – that would have been rude – but he did utilize the platform [...]... Read more »
