One species, many genomes

...he genome of a species," says Weigel. He adds "The insight that the DNA sequence of a single individual is by far not sufficient to understand the genetic potential of a species also fuels current efforts in human genetics." Still, it is surprising that Arabidopsis has such a plastic genome. In contrast to...

Cellular message movement captured on video

...lin and actin filaments move together we have some insight into the possibility of how paxillin can transmit information from one region of the cell, such as the periphery, to another region of the cell, such as the nucleus,” said Chien. “The whole situation is much more complex than we have been able to sho...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

New findings challenge established views on human genome

...an evolution. In particular, we gained significant insight into DNA sequences that do not encode proteins, which we knew very little about before,” said Ewan Birney, Ph.D., head of genome annotation at the European Molecular Biology Laboratory’s European Bioinformatics Institute (EBI) in Hinxton, England, wh...

Exploring the dark matter of the genome

...in's organization and constitution, and led to new insight into how it helps cells and organisms survive. The latest results from the DHGP are reported in a pair of papers in the June 15, 2007 issue of Science. The annotated heterochromatic sequences reveal over 200 protein-coding genes. The heterochroma...

Detecting cold, feeling pain: Study reveals why menthol feels fresh

...thresholds for temperature are determined, we gain insight into how these thresholds change in the setting of injury, such as inflammatory and nerve injury, and how these changes may contribute to chronic pain," says senior author David Julius, PhD, chairman and professor of physiology at UCSF. The metha...

... area. This is a finding which gives us a critical insight into cheetah ecology and one that merits inclusion into future conservation efforts for the species.” The nine-year study, which was conducted in the Serengeti National Park of Tanzania, focused on determining the paternity of cheetahs through the...

How to look at dinosaur tracks

...sue of The Journal of Geology provides fascinating insight into the factors geologists must account for when examining dinosaur tracks. The authors studied a range of larger tracks from the family of dinosaurs that includes the T. Rex and the tridactyl, and provide a guide for interpreting the effects of man...

How the brain's backup system compensates for stroke

...as happens during stroke. Their finding offers new insight into how the brains of stroke victims can quickly reorganize to enable the beginning of recovery of movement. Jacinta O'Shea and colleagues at the University of Oxford reported their findings in the May 3, 2007 issue of the journal Neuron, published...

Diminishing dinosaur steps saved by laser and laptop

...d dinosaur locomotion experts, because it gives an insight into the way these dinosaurs moved and the environments in which they lived. The on-going project - run in conjunction with Universitat Autonoma de Barcelona - is being led by palaeontologist Dr Phil Manning, who received a grant of Euro 9,000 fro...

Baumann Lab defines proteins that distinguish chromosome ends from DNA double-strand breaks

...n the Baumann Lab, have published a paper offering insight into the way cells protect chromosome ends from misguided repair. Published in tomorrow's issue of Molecular Cell, their paper entitled "A RAP1/TRF2 Complex Inhibits Non-Homologous End Joining at Human Telomeric DNA Ends" employed a biochemical ass...

Researchers develop way to calculate speed of bacterial sex

... gene transfer, UC-Davis researchers hoped to gain insight into the rates of bacterial adaptation in the environment. They report their findings in the May 2007 issue of Vadose Zone Journal in a special section on soil biophysics. Researchers believe that one of the major mechanisms for the transfer of ge...

In young mice, gregariousness seems to reside in the genes

...important because it provides the first scientific insight that genes contribute to a novel form of natural reward - the pleasure of interacting with other juveniles. At a practical level, the new findings provide a foundation for understanding the motivations that underlie acts of altruism. Moreover, the wo...

Scientists see DNA get 'sunburned' for the first time

...to bond when the UV hits, or they're not. "This insight explains why some pairs of thymine bases get damaged more frequently than others, and it suggests that scientists can understand damage patterns to DNA by studying the factors that influence how the bases are arranged in space," Kohler said. "In o...
