A new world of research possibilities with 'Emerging Model Organisms'

A representative collection of the emerging model organisms described in the book are shown. Clockwise from the top are the comb jelly (Ctenophora) the sea lamprey (Petromyzon marinus) an example of Darwins finches (the Galapagos finches) the nematod ...

Local Retail Meat Safe From Antibiotic-resistant Organisms, Study Suggests

Rhode Island Hospital researchers report that findings from a new study of retail meat in the Providence, RI area indicate little to no presence of antibiotic-resistant bacteria. The study, prompted by the identification of such organisms in retail meat in Canada, Europe and Asia, is among the first in this country to look at the possible spread of infection through retail meat.

Rhode Island Hospital study finds local retail meat safe from antibiotic-resistant organisms

Providence, RI –Rhode Island Hospital researchers report that findings from a new study of retail meat in the Providence, RI area indicate little to no presence of antibiotic-resistant bacteria. The study, prompted by the identification of such organisms in retail meat in Canada, Europe and Asia, is among the first in this country to look at the possible spread of infection through retail meat. The study was published in the Journal of Food, Agriculture & Environment, Vol. 6 (3&4), 2008.

How evolution learns from past environments to adapt to new environments

The evolution of novel characteristics within organisms can be enhanced when environments change in a systematic manner, according to a new study by Weizmann Institute researchers. Merav Parter, Nadav Kashtan and Uri Alon suggest that in environments that vary over time in a non-random way, evolution can learn the rules of the environment and develop organisms that can readily generate novel useful traits with only a few mutations. Details are published November 7 in the open-access journal PLoS Computational Biology.

Adaptive proteins "control" their own evolution

A previously hidden mechanism that guides the way biological organisms respond to the forces of natural selection has been observed making the proteins found in most living organisms behave like adaptive machines, subtly directing aspects of their own evolution to create order out of randomness. Researchers Raj Chakrabarti, Herschel Rabitz, Stacey Springs and George McLendon made the discovery while carrying out experiments on the proteins constituting the electron transport chain (ETC), a biochemical network essential for metabolism.

Evolution's New Wrinkle

A team of Princeton University scientists has discovered that chains of proteins found in most living organisms act like adaptive machines, possessing the ability to control their own evolution. The research, which appears to offer evidence of a hidden mechanism guiding the way biological organisms respond to the forces of natural selection, provides a new perspective on evolution, the scientists said.

Transporting Broiler Chickens Could Spread Antibiotic-resistant Organisms

Researchers at the Johns Hopkins Bloomberg School of Public Health have found evidence of a novel pathway for potential human exposure to antibiotic-resistant bacteria from intensively raised poultry — driving behind the trucks transporting broiler chickens from farm to slaughterhouse.

Transporting Broiler Chickens Could Spread Antibiotic-Resistant Organisms

Newswise - Researchers at the Johns Hopkins Bloomberg School of Public Health have found evidence of a novel pathway for potential human exposure to antibiotic-resistant bacteria from intensively raised poultry--driving behind the trucks transporting broiler chickens from farm to slaughterhouse. A study by the Hopkins researchers found increased levels of pathogenic bacteria, both susceptible and drug-resistant, on surfaces and in the air inside cars traveling behind trucks that carry broiler chickens. The study is the first to look at exposure to antibiotic-resistant bacteria from the transportation of poultry. The findings are published in the first issue of the Journal of Infection and Public Health.

Sea creature leaves trail of evolutionary clues

Single-cell organisms are found rolling along the ocean floor, leaving animal-like tracks that researchers had thought could be made only by complex creatures.

First images of barnacle larva's footprint

The fouling or growth of sea organisms, such as barnacles, on ships' hulls causes damage costing many billions of euros annually. In order to prevent this fouling, In Yee Phang of the University of Twente [profile] (Netherlands) used nanotechnology to investigate how barnacles colonize a surface. This is the first time that the existence of barnacle cyprid larvae "footprints" has been demonstrated. Phang will be awarded his doctorate on 24 October at the faculty of Science and Technology.

Netflix Cuts Off HD DVD Rentals Starting December 15

This zany lamp created by Marieke Staps outdoes most lamps in more ways than one: the electricity is powered through the organisms contained in the mud. The mud is enclosed in cells that contain copper and zinc, which conducts the electricity in the LED. Besides doing wonders for your energy bill, Staps claims that the only thing the lamp needs is a "splash of water" every now and then. I wouldn't stand too close when you are doing it though, or the end result might be akin to sticking a live hair dryer in your bathwater. [Marieke Staps via MAKE]
