Students discover 11,000 year old remains of Irish Elk

...ins, which will now be scientifically dated, could add to growing evidence that giant deer were present on the island much later than palaeozoologists originally thought. The antler was found in a 'kettle hole' ?a hollow created when blocks of ice melt, now exposed in the eroding the cliff face. Its stra...

Looking for the genes that affect a person's level of response to alcohol

... said Hesselbrock. "What Dr. Schuckit has done is add another set of genes to that pool. It may be a small step, but that certainly doesn't diminish the importance of the finding." ...

The shape of things to come: Morphology database going global

...cience department. Scientists also will be able to add comments to the images and search comments made by other scientists - a quick and efficient way to communicate research results. "We're hoping to achieve a change in the way scientists work when they do research," Ronquist said. "That's one of the b...

Sickle cell disease corrected in human models using stem cell-based gene therapy

... proved our hypothesis that you can simultaneously add one function and delete another in the same cell and obtain synergistic genetic modifications within a single cell," said Selda Samakoglu, PhD, a member of Dr. Sadelain's laboratory and the study's first author. "In this case, we used the technique t...

Plant wounds trigger bacteria

... plant wound; the phenols, in turn, signal VirA to add a phosphate (PO4) group to a related protein, VirG, converting it into an active form. The new study shows that the activated form of VirG causes the tumor-inducing plasmid to replicate up to five times faster than normal by increasing the expressi...

Living anti-HIV gel shows early promise

...e easy to produce, store and distribute. But they add that before human trials can begin, researchers will need to ensure that the microbes are better able to colonise the reproductive and intestinal tracts. Other issues that will need to be addressed include the safety of introducing live, genetically...

Chernobyl: The true scale of the accident

...e accident were potentially horrific, but when you add them up using validated conclusions from good science, the public health effects were not nearly as substantial as had at first been feared." The report's estimate for the eventual number of deaths is far lower than earlier, well-publicized speculat...

Restaurant seafood prices since 1850s help plot marine harvests through history

... More than 75 presentations at the conference will add greatly to what is known about ocean life in the past, and delineate what is unknown but discoverable, and what may be unknowable about the world's oceans. Fish: Food for all Ages "Fish has been part of peoples' diets since humans first walked the ...

Biotechnology's newest chemical tool

...ny, have harnessed a group of essential enzymes to add various chemical groups to DNA, thereby altering its function. The work was published in an early online publication on November 27, 2005 in Nature Chemical Biology. The enzymes at the heart of the study, known as DNA methyltransferases, are one of...

NC State researchers redesign life for Mars and beyond

...ery fundamental research," Boss said. "If we could add new genes to plants, we could potentially make the plants more resistant to extreme conditions such as drought and extreme temperatures that we have on Earth, but also to the extreme conditions that one might find on Mars." Now that the concept of i...

Researchers find Amchitka seafood safe for now

...e, within the very short single season of work, to add so significantly to the geophysical understanding of Amchitka and its marine environment. I worked with excellent teams from four good research universities." David Kosson, head of the CRESP Remediation Center of Expertise and Professor and Chair, th...

Bone marrow stem cells may heal hearts even years after heart attacks

... this type of stem cell infusion, the results help add evidence that the treatment may provide meaningful benefits to patients. "Strauer et al. provide this indirect evidence of muscle regeneration using a simple technique to isolate mononuclear cells from the patient's own bone marrow, then transplanti...

Scientists discover new way to look at how molecules twist and turn on water

... experiments and computer modeling. These studies add important new insights into ongoing studies in the Richmond laboratory that seek to understand how these surfactant head groups change the properties of water at aqueous surfaces. ...

Techniques available to detect soil that inhibits destructive soybean pest

...development. Another confirmation technique was to add suppressive soil to soils conducive to nematode development. The researchers also were able to document reduced nematode reproduction, population density, and whether certain types of soil were suppressive to specific pathogens. "Currently, we are e...

New NIAID grants strengthen national biodefense and emerging infectious diseases research network

...nsmitted to people by mosquitoes. The centers also add expertise in hantaviruses, as well as in the development of diagnostics and animal models of disease. Each consortium within the network will * support investigator-directed research * train researchers and other personnel for biodefense re...

Freeze-dried mats of microbes awaken in Antarctic streambed

...n entire ecosystem in about a week. All we did was add water." McKnight gave a presentation on the experiment at the Ecological Society of America's 90th Annual Meeting held Aug. 7 to Aug. 12 in Montreal. The river channels under study feature intermittent streams that link glaciers to frozen lakes on...

Scientists create digital bacteria to forge advances in biomedical research

.... "The hope is that people will modify the code or add some new capabilities. The code will soon be available for download from our Web site, http://www.agentcell.org," Emonet said. AgentCell has already yielded benefits in Cluzel's laboratory, even in its current rather simple configuration. In his sim...

Two designer drugs hit same lung cancer target, but only one is effective

...te, the researchers say that the divergent results add to growing evidence that mutations in the targets of designer drugs critically influence their effectiveness. Erbitux is an effective inhibitor of EGFR signals in colorectal cancer, which involves a normal, not mutant, EGFR molecule. "We now know of...

Modification of program enables prediction of gene transcription

...none-too-sure industry. "We've found that when we add the spliced untranslated regions to our system, we not only get good predictions for UTRs but also improved predictions of the protein-coding region of the gene. By correctly identifying UTRs, we can avoid labeling them incorrectly as part of the pro...

Treatments have same target, different responses for lung cancer patients with genetic mutation

...s won by [drugs such as gefitinib]." However, they add that additional research should focus on the effects of cetuximab on certain populations of patients, or used in conjunction with other drugs. "Cetuximab may still have an effective punch if the right circumstances can be identified," the authors con...
