CDC and Texas Health Department confirm first Ebola case diagnosed in the U.S.
The Centers for Disease Control and Prevention (CDC) confirmed today, through laboratory tests, the first case of Ebola to be diagnosed in the United States in a person who had traveled to Dallas, Texas from Liberia. The patient did not have symptoms when leaving West Africa, but developed symptoms approximately four days after arriving in the U.S. on Sept. 20.

Blades of grass inspire advance in organic solar cells
Using a bio-mimicking analog of one of nature's most efficient light-harvesting structures, blades of grass, an international research team has taken a major step in developing long-sought polymer architecture to boost power-conversion efficiency of light to electricity for use in electronic devices.

Study shows how chimpanzees share skills: Evidence of new behavior being transmitted socially
Biologists have found evidence of new behavior being adopted and transmitted socially from one individual to another within a wild chimpanzee community. This is the first instance of social learning recorded in the wild.

First comprehensive meshfree numerical simulation of skeletal muscle tissue achieved
(University of California - San Diego) Engineers at the University of California, San Diego, have completed the first comprehensive numerical simulation of skeletal muscle tissue using a method that uses the pixels in an image as data points for the computer simulation -- a method known as mesh-free simulation.The researchers, led by J.S. Chen, a professor of structural engineering at the Jacobs School of Engineering at UC San Diego, presented their findings on the development of this method at the CompIMAGE'14 conference in Pittsburgh this month.

Organ donation: Do we opt-in or opt-out?

Researchers say there should be an international database containing the very latest information about organ donations and transplants, so policy makers can make informed decisions on whether to adopt an opt-out or opt-in system.

Insect genomes' analysis challenges universality of essential cell division proteins

Cell division, the process that ensures equal transmission of genetic information to daughter cells, has been fundamentally conserved for over a billion years of evolution. Considering its ubiquity and essentiality, it is expected that proteins that carry out cell division would also be highly conserved. Challenging this assumption, scientists from Fred Hutchinson Cancer Research Center have found that one of the foundational proteins in cell division, previously shown to be essential in organisms as diverse as yeast, flies and humans, has been surprisingly lost on multiple occasions during insect evolution.

Microbes in Central Park soil: If they can make it there, they can make it anywhere
Soil microbes that thrive in the deserts, rainforests, prairies and forests of the world can also be found living beneath New York City's Central Park, according to a surprising new study led by Colorado State University and the University of Colorado Boulder.

Protected areas offer glimmers of hope for wildlife
National parks and other protected areas offer hope for threatened species at a time of plunging wildlife numbers, conservationist group WWF said Tuesday, but their success has not been universal. Biology News, Wed, 01 Oct 2014 06:10:33 GMT

Geneticists solve 40-year-old dilemma to explain why duplicate genes remain in the genome
Geneticists at Trinity College Dublin have made a major breakthrough with important implications for understanding the evolution of genomes in a variety of organisms. Biology News, Wed, 01 Oct 2014 06:10:33 GMT
