Four Arnoux's Beaked Whales observed from Polarstern expedition

...ons beneath the Larsen Ice Shelves and how do they differ from "normal" areas. A catch with the Agassiz trawl was bountiful and also provided sponges, the most distinct group of animals living on the seafloor in the shelf ecosystem. As the first working groups are supplied with organisms scientific work is ...

Development of gene therapy

...t assessment, although in this respect it does not differ substantially from other therapeutic approaches. Gene therapy is defined as the introduction of genes into tissues or cells via gene transfer, with the purpose of deriving a therapeutic or preventative benefit from the function of these genes. Gene ...

Scientists develop method to find genetic basis for plant variation

...t said. The first question was how those plants differ from the "garden-variety" Arabidopsis. This is not a simple question, he said, which is why so few studies have been published concerning the precise genetic basis of natural variation. The initial difficulty is that to date only one variety of Ar...

Plant biologist seeks molecular differences between rice and its mimic

...ndidate genes that underlie particular traits that differ between the two," said Olsen. "Knowing more about the traits could help in potentially controlling the weed. We have a key advantage in this research in that we know the complete cultivated rice genome, so it's fairly easy to target genes of interes...

Too mellow for our predatory world

...ions and with different predator-experiences would differ in terms of stress response and behaviour. To this end the researchers conducted so-called "harassment experiments". At first, they recorded the original flight initiation distance of "naïve" animals. The researchers then experimentally chased the an...

Dental crowns reveal the diet of a species

... For instance, the teeth of carnivores and rodents differ in almost every aspect, but if a carnivore and a rodent eat similar food, their teeth are equally complex. The results were published in Nature. The size, number, occlusion and dental crown cusps of carnivores and rodents, such as cats and mice, are...

All itches not created equal -- Different parts of brain activated depending on cause

...parts of the brain that are activated by allergens differ when compared to histamine. As a result, mothers who admonish their children to stop itching may now be rightly told I cant. For mold and grass-related itches, it appears that science is on their side....

A chilling solution: Measuring below-ground carbon without destroying trees

...s hypothesized that carbon movement in trees would differ at varying points in the year; this was confirmed in their study. "There was no response to either chilling or physical girdling in the experiments we did in the spring," says Johnsen. "We think this is because above-ground growth was so rapid and...

Research yields new insights into the cause of diabetes

... glucose and generate energy. PERK-deficient mice differ significantly from normal mice. At birth, PERK-deficient mice have only about one-half the mass of beta cells that normal mice have. During the first few weeks after birth, PERK-deficient mice have fewer and fewer beta cells compared to normal mice...

Springer adds Genomic Medicine to biomedical publishing portfolio

...or for Life Sciences, said, "Genomic Medicine will differ from conventional human and medical genetic journals by concentrating exclusively on genomic applications to medical disorders. We are pleased to add Genomic Medicine to our portfolio, providing an outlet for specialists in all genome-related fields...

Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

...or the correct RNA building blocks, molecules that differ by only one oxygen atom. In search of an explanation in the current study, the researchers screened hundreds of crystals to achieve higher data quality and resolution than ever before. In the course of the work, we saw something that had never been...

Lemurs' fur color may not define species

...genetic analysis reveals that the 70 lemurs do not differ genetically. According to their cytochrome b sequence, they all belong to the same, previously identified species, Microcebus griseorufus. The authors also show that the three different coat colours observed are found in all three geographical locati...

Different coat color may not mean different species for lemurs

... because they were visually distinct, they did not differ genetically. According to the sequence of their cytochrome b genes, all belong to the same previously identified species, Microcebus griseorufus. The authors also show that lemurs with each of the three different coat colors could be found in all t...

Diet can provide protection against development of certain cancers, new studies show

... They found that mean cholesterol levels did not differ between the men with prostate cancer and the control participants, suggesting that cholesterol was not involved in the initial development of prostate cancer, Platz said. But when comparing men who had the lowest quartile of serum cholesterol to me...

The people at Qumran thought that you could look at body types and tell what kind of person you were. Josephus tells us that th...

However, mouse pups from a single litter differ from each other in their coat color (from yellow to brown), obesity (thinner to fatter), and susceptibility to cancer, and all of these varied traits can be traced back to the Avy version of the agouti gene. The mouse model also suggests that similar...

A prickly subject: The sea urchin genome is sequenced

...s, sharing most of the same gene families, and yet differ in a few critical areas besides the obvious physical ones. For one thing, sea urchins have a "extraordinarily complex innate immune system" which is not based on antibodies, like that of jawed vertebrates, but is effective enough to give sea urchins...
