Insects, viruses could hold key for better human teamwork in disasters

...empting to draw inspiration from the collaboration patterns that honeybees and ants use, and the spread patterns viruses typically take. The ideas the researchers develop will "augment current collaboration among...

Scientists analyze chromosomes 2 and 4

...f time by searching other mammals' DNA for similar patterns of duplication," said Richard K. Wilson, Ph.D., director of the Washington University School of Medicine's Genome Sequencing Center and senior author of the study. In another intriguing finding, the researchers identified a messenger RNA (mRNA) tran...

At the molecular level, the predator is the prey

..., either by altering existing genes or by changing patterns and amounts of expression. The current Nature report shows that snakes' ability to detoxify TTX involves changes in the sodium channel gene. "That is generally the story as it is developing," Brodie said. "Ecological arms races that go on between pr...

DOE JGI launches IMG public online microbial genome data clearinghouse

...owerful tool for understanding everything from the patterns of mutation to adaptation," said Taylor. "Computational biologists have led the way, but IMG makes it possible for evolutionary biologists without first-rate computer skills to compare fungal and bacterial genomes and scrutinize fundamental processes...

Major new UNC-based drinking water study suggests pregnancy fears may be overstated

...ive information on the volunteers, including their patterns of water use such as drinking and bathing and what later happened with their pregnancies and births. Among tests the women underwent were ultrasound examinations to collect more detailed information about their pregnancies. Researchers then, after a...

Ancient DNA helps clarify the origins of two extinct New World horse species

...ough the region undergoes high mutation rates, the patterns of mutations remain stable over thousands of generations. The mtDNA analysis of the South and North American horses provided evidence that stilt-legged horses, the Hippidion genus, and caballine, or true horses, all arose from a common lineage. The ...

Map of life on Earth could be used on Mars

...bitat divergence among bacteria is consistent with patterns of divergence among the other prokaryotes, Blank's...ecosystems. So the literal interpretation of these patterns is that early habitat specialization could have lasted for a billion years." After mapping early ha...

Where Bacteria Get Their Genes

...tibiotics, it's important to monitor the rates and patterns of lateral gene transfer," said team member Howard Ochman, a UA professor of biochemistry and molecular biophysics and a member of UA's BIO5 Institute. The research also solves a long-standing evolutionary puzzle. Many scientists have argued that dr...

Bioinformatics reveals new gene regulation system

A whole lot of shaking goin' on triggers early hatching in red-eyed tree frogs

...s, therefore, provided more evidence that temporal patterns serve as an important cue for the frogs. Warkentin created similar temporal patterns out of computer-generated nonspecific sound, or "white noise." Again, the snake-like pattern of whit...

New tool reveals secrets of migrating cells

... beginning. The human eye and brain can't pick out patterns of movement easily, so statistical techniques are needed to identify cells with different patterns of movement. As an immunologist, Robey focuses on the lives of T cells produced in the thymus and d...

Scientists find microRNAs regulate plant development

...roots, and floral organs to develop in the correct patterns and correct time sequence. Research reported in The Plant Cell shows that microRNAs control the accumulation of transcription factor proteins that regulate the expression of genes in the auxin response pathway. Messenger RNA (mRNA) molecules are enc...

TGen awarded $7.1 million to accelerate brain disease research

Using this information, investigators can identify the root causes responsible for certain disorders so that diagnostics and treatments can be developed that have a direct impact on the d...

Drawing with DNA: 'Bioart' illuminates genomics

...lexity of sequence codes to the sorts of shapes or patterns that a human being can make sense of," West said. "It is an artistic approach to extracting what's important. And it is also an exploration of what art might have to offer for discovery in the sciences." "Ecce Homology" premiered in 2003 at the UCLA...

This systematic association of croup with HCoV-NL63 is particularly timely as the newly identified virus has spread worldwide, reported in Australia, Japan, the US and Canada. The study will also contribute towards the clar...

Looks matter to female barn swallows
