A rarity among arachnids, whip spiders have a sociable family life

...at the siblings grouped together but changed their location daily, suggesting individuals preferred proximity to each other over a specific location. When siblings were removed from a familiar cage and scattered about another large unfamiliar cage, within minutes, they gathered back together. In one experim...

Wheat can fatally starve insect predators

... insect-plant interactions. Knowing the timing and location of those interactions would enable the scientists to use the promoter tactic only in the vegetative parts of the wheat plant rather than in the head or grain portions. This will protect the grain quality and the consumer. "Once we understand which...

Protein sensor for fatty acid buildup in mitochondria

.... "Our study showed the connection between the location of PanK2 in the mitochondria and its role in as a ... and the report's senior author. "This is an ideal location for PanK2 because it can detect acylcarnitine as it enters the mitochondrion." The importance of...

Prenatal cocaine's lasting cellular effects

...n. However, there was a dramatic alteration in the location of the protein within the cell. "It's not where it should be," he said. D1 receptors are normally found at the cell surface, but neurons from the cocaine-exposed animals showed the receptor was predominantly sequestered inside the cells. "The...

Scientists map key landmarks in human genome

...cations. The technique successfully pinpointed the location of some nucleosomes previously found through other means, but the new method can be applied to the entire genomes of human and other cells, said the scientists. In the future, the techniques might be useful as a diagnostic tool, Fisher said. "G...

UCLA scientists design masks to hide genetic mutations from cell

...netic defects and restores splicing to the correct location in the gene. IMPACT: The laboratory findings suggest a powerful new approach for treating cancer and other diseases caused by genetic mutations. The researchers?next step will be to test their findings in a mouse model. AUTHORS: Dr. Ric...

Largest genomic search finds genes that may contribute to autism

...y unidentified region of another chromosome as the location of another gene that may contribute to a child's chances of having autism. The findings, based on genetic samples from nearly 1,200 families with two or more children who have autism, were published today in Nature Genetics by more than 120 scientis...

Scientists map air pollution using corn grown in US fields

... of carbon dioxide produced by fossil fuels at the location where the corn samples were collected. California and the Ohio Valley had the most fossil-fuel-emitted carbon dioxide, while the Colorado region had the least. The scientists expected pollution from California and other western coastal states to d...

Liposuctioned fat stem cells to repair bodies

...t regenerating tissue. Uncovering the nature and location of these molecular tags could allow scientists to pull off the ultimate trick of taking a patient’s own fat cells and using them for therapy, Collas told researchers gathered at the EuroSTELLS Workshop ‘Exploring Chromatin in Stem Cells?held on Janua...

Cryoablation -- A new treatment option for some kidney tumor patients

...roximity of tumor to ureter or bowel, or a central location on the kidney. Cryoablation was successful in 38 of the 40 patients, with no repeat treatment necessary. In percutaneous cryoablation, one or more hollow needles are inserted through the skin directly into a tumor. Doctors can observe and guide ...

Scientists reveal structure of gateways to gene control

...omes. The scientists then pinpointed the original location of the H2A.Z nucleosomes by matching the sequence of each one with the identical sequence on the previously published yeast genome. "Obtaining the exact DNA sequences for all these nucleosomes allows us to precisely map their positions across the en...

MIT bioengineer advances survival, promise of adult stem cells

...because then you can control the concentration and location and so forth," Griffith said. The ceramic and polymer scaffold, which remains in the patient's body during healing but then resorbs, also provides structure for the stem cells as they grow into new bone cells. "We found that when EGF was tethered...

A sweet step toward new cancer therapies

...dentify sulfate-laden proteins and to pinpoint the location of the sulfate groups on them. In the latest research, they extended the technique to sugars, an even more challenging task. "Sugars are not like other biomolecules," Hakansson said. "They're linked rings with lots of branches, like trees. If y...

Dig deeper to find Martian life

...for living cells is within the ice at Elysium, the location of the newly discovered frozen sea on Mars. The lead author, Lewis Dartnell, UCL Centre for Mathematics and Physics in the Life Sciences & Experimental Biology (CoMPLEX), said: "Finding hints that life once existed ?proteins, DNA fragments or...

New fMRI technology making brain tumor surgery safer

...Dr. Leach processes those images, highlighting the location of speech and movement areas and white matter tracts. He also highlights the tumor location, then imports all of the information into BrainLAB’s navigation software at University Hospital. The Neuroscience Institute, a regional center of excellenc...

Stress hormones may play new role in speeding up cancer growth

...loodstream. From there, they can travel to another location in the body to form additional tumors, a process called metastasis. The research also suggests the same hormone can also stimulate the tumor cells to release another compound that can aid in the growth of new blood vessels that feed cancer cells, ...

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

...ally dependent upon the base, sugar, phosphate and location when the trigger loop swings into position,?Kornberg said. “If it is misaligned even slightly, that set of contacts cannot occur.? As a consequence of that alignment, to angstrom (a unit of length equal to one hundred millionth of a centimeter) prec...

Invasive ants territorial when neighbors are not kin

...did not fight when placed with ants from a distant location in the same supercolony. Coauthors Christine Payne-Makrisâ and Andrew Suarez from the University of Illinois, Urbana and Neil Tsutsui from U.C. Irvine found that across the large geographical range of a supercolony ants were very genetically similar...
