The creatures are covered in a thick, protective layer or lorica. Scientists have found the first animals that can survive and reproduce entirely without oxygen, deep on the floor of the Mediterranean Sea. The team, led by Roberto Danovaro from Marche Polytechnic University in Ancona, Italy, found three new species from the Loricifera group. He [...]
Arabidopsis. A new study located dozens of genes that may determine key traits such as flowering time and disease resistance. (Credit: iStockphoto) ScienceDaily (Mar. 29, 2010) — A method pioneered to find the genetic basis of human diseases also holds promise for locating the genes behind important traits in plants, according to a study published [...]
ScienceDaily (Mar. 11, 2010) — A three-year field program now underway is measuring carbon distributions and primary productivity in the Northwest Atlantic Ocean to help scientists worldwide determine the impacts of a changing climate on ocean biology and biogeochemistry. The study, Climate Variability on the East Coast (CliVEC), will also help validate ocean color satellite [...]
Biologists discovered a specific region of genes involved in the genomic adaptation of saltwater populations of stickleback fish to freshwater lakes in Alaska. (Credit: Image courtesy of University of Oregon) ScienceDaily (Mar. 8, 2010) — Twenty billion pieces of DNA in 100 small fish have opened the eyes of biologists studying evolution. After combining new [...]

ScienceDaily (Feb. 9, 2010) — Biologists have known for long that ecology, the interaction between organisms and their environment, plays a significant role in forming new species and in modifying living ones. The traditional view is [...]
A newly developed organic transistor has opened the way to new generations of neuro-inspired computers, capable of responding in a manner similar to the nervous system. (Credit: iStockphoto/Andrey Volodin) ScienceDaily (Jan. 29, 2010) — For the first time, CNRS(1) and CEA(2) researchers have developed a transistor that can mimic the main functionalities of a synapse(3).

HUMANS living millions of years ago were endurance runners, but how did they do it without air-cushioned soles? The secret might have been to land on the balls of their feet. Run on tip-toe like your ancestors (Image: Tatiana Morozova/iStock) HUMANS living millions of years ago were endurance runners, but how did they do it [...]
Scientists have found a striking similarity in the DNA that enables some bats and dolphins to echolocate. The bottlenose dolphin is a toothed whale that uses echolocation. (J. Hill) A key gene that gives their ears the ability to detect high-frequency sound has undergone the exact same changes over time in both creatures. The researchers [...]
The DiCarlo Lab (McGovern Institute for Brain Research at MIT) and the Cox Lab (Rowland Institute at Harvard University) have built this 16-GPU 'monster' supercomputer as part of their research efforts to build artificial vision systems inspired by the human brain. The 18" x18" x18" cube may be one of the most compact and inexpensive [...]
ScienceDaily (Dec. 4, 2009) — In contrast to the exhaustive research into venom produced by snakes and spiders, venomous fish have been neglected and remain something of a mystery. Now, a study of 158 catfish species, published in the open access journal BMC Evolutionary Biology, has catalogued the presence of venom glands and investigated their [...]
