Scientists describe the world's smallest, lightest fish
...opment, but they may have the ability to evolve as fast
as their environment changes." Philip Hastings, the curator of the Scripps Marine Vertebrates Collection, says the identification of the stout infantfish is another demonstration that scientists do not yet possess a complete inventory of marine anima...
90 million year old dino tracks found on resort island
.... This information is important for estimating how fast
the dinosaurs were walking and how big they were by measuring the distance between their footprints. Originally, Caldwell and Radovcic went to the island of Hvar to search forfossils of marine lizards and snakes. Fossils of these animals were first...
Rutgers chemist uses NMR to elucidate protein-DNA interaction
... of how proteins and DNA find each other in a very fast
and accurate way. It provides us with a classical model for understanding protein-DNA interaction and offers valuable information about how transcription can be modulated at the gene level." ...
Carnivore species are predicted to be at increased extinction risk from human population growth
...ecies with long gestation periods can't repopulate fast
enough and become endangered. Based on projected human population growth, the researchers predict that many carnivore species will join the list of endangered species list by 2030. Most of these species live in Africa, where human populations are gro...
When sun's too strong, plankton make clouds
...les that break down DMS scream along at these very fast
rates, even though overall amounts over the course of the year remain pretty stable with a slow increase over summer and a gradual decline over winter. The next step for the researchers will be to see how much the added clouds from plankton actually...
New lower-cost assay system equivalent to flow cytometry for accurate CD4+/CD8+ cell counts
...g the system. Daily maintenance is minimal just a fast
and easy 5 minute clean and shutdown procedure performed at the end of each day. "The Guava EasyCD4 and EasyCD8 enable easy monitoring of T cell health in HIV-infected patients, using a benchtop system that is reliable and robust, and that provides r...
Open Access journals proven to compete on quality
...Open Access to research literature achieves impact fast
and makes quality articles much more widely visible. Arthritis Research & Therapy jumped from 3.44 to 5.03, propelling it to rank second in the rheumatology field in only its 6th year of publication. Breast Cancer Research also increased its impact f...
Survival of the fastest: scientists 'selectively breed' winning Formula One cars
...f the study, explains: "Silverstone is generally a fast
circuit with several slow corners and a selection of fast
sweeping turns. This allowed us to test cars that are tuned for higher speed, with less down force f...
UK researchers develop way of predicting a woman's 'reproductive' age
... have the potential to be able to tell a woman how fast
her biological clock is ticking and how much time she has before it will run down," said lead author Dr. Hamish Wallace, consultant paediatric oncologist at the Royal Hospital for Sick Children in Edinburgh, Scotland and a senior lecturer at the Univ...
A gene that keeps species apart
...s itself. Darwin demurred from offering a hard and fast
definition, suggesting that such a thing was "undiscoverable." In this issue of PLoS Biology, Daniel Barbash and colleagues identify a true speciation gene in the fruitfly Drosophila. One of the more enduring definitions characterizes organisms as...

Tiny tango: Device sorts microscopic particles with speed and precision
...s for sorting DNA and other particles, but none as fast
and precise as the tango array. The trade-off between speed and precision had seemed insurmountable, said Huang, who has been building and testing sorting devices for nearly six years. The breakthrough came when a collaborator in the physic...
Researchers establish first molecular link between eating and aging
... the bloodstream, fat cells also tell the body how fast
to age. "Conversely, fewer fat cells tell the body that it's time to hunker down for survival. This means that evolutionarily speaking, fat plays a very important role," he said. We know already fat or lack of it has vast implications in the live...

rotating Bose gases (G2 2). Deborah Jin of NIST/JILA will describe her group's recent experiments with degenerate gases of cold potassium atoms in the "crossover region," in which the interactions between atoms can be tuned by varying the external ma...
BioCDS could hit No. 1 on doctors' charts

method of detecting these biological molecules would be a welcome addition to any doctor's office. But with current technology, blood samples are sent to laboratories for analysis - a procedure that only screens for a few of the thousands of proteins...
ASU advance could provide insight into human's ability to recognize patterns

computation that humans cannot do, but humans can recognize patterns so much better than computers," Lai said. "The question is why. What is the fundamental mechanism that a biological system like us can make use of and try to memorize patterns." A k...

Penguins ingest mollusk shells to obtain calcium for thicker eggshells
