Scientists question reports of massive ant supercolonies in California and Europe

...rent markers that are more variable, which made it easier to detect genetic variation among different colonies." The genetic work at Jasper Ridge shows that there are definite barriers to gene flow, Heller added. "We've also found that the distribution of Argentine ants on Jasper Ridge is patchy," she ...

Genetic trick adapted from viruses makes gene therapy vectors more versatile

... "We expect that this technique will make it a lot easier for us to study the role of complex protein structures," Vignali said. "These 2A peptides may also facilitate the development of more versatile gene therapy vectors for treatments that require replacement or expression of more than a single gene." Ot...

Three new South American fish identified

...d about biodiversity," Lopez-Fernandez said. "It's easier to preserve a species if you know it's there. It's very hard to attach a value on something until you know what it is." One of the most endearing features Lopez-Fernandez realized about the Geophagus fish in his research is that the parent fish take...

Creating polymers that act like biomolecules

... much more stable, readily available and therefore easier to study." Because they are easier to work with, the polymers could potentially be modified and used as a way to deliver drugs or gene ...

News tip: Duke marine biologist calls for whale-proof fishing gear

... slow the animal down. "But humpback whales are easier to disentangle than right whales," he says. "Right whales are stronger and less amenable to work with. They can be very aggressive. They'll thrash their tails. People have had much less success disentangling them. "And the stakes are much higher,"...

Rockefeller University scientists take on controversial 'vibration theory' of smell

...ent in size the aldehydes are from each other, the easier it is for the human subjects to tell them apart." The final experiment, a test of both the shape and vibration theory, is based on Turin's proposal that two chemicals that have almost identical shapes (acetophenone and deuterated acetophenone) have m...

New toxicity test could cut animal testing

...opulations assays using these cells should also be easier to standardise than current tests, which use heterogeneous primary cell cultures. As there is considerable discomfort about the use of animals in research, researchers have tried to develop methods that reduce our reliance on animal experiments. Alth...

Johns Hopkins gene hunters pinpoint new cancer gene target

...," thus making molecular diagnostic tests possibly easier to develop. "These mutations, added to a panel of existing markers for colon cancer developed in our laboratory, could help find cancers that would otherwise go undetected," says Yardena Samuels, Ph.D., postdoctoral fellow and first author of the stu...

Common virus may contribute to uncommon bone disease in children

... new study. The research may eventually lead to an easier diagnosis and to more effective treatments of the disease, Langerhans cell histiocytosis. Researchers found evidence of the virus, human herpesvirus 6 (HHV-6) in the tissues of 25 of 35 children with Langerhans cell histiocytosis (LCH), compared to v...

New human embryonic stem-cell lines to be made available to researchers

...he course of their experiments, they discovered an easier way to tease stem cells free from surrounding tissues by using enzymes. "One of the things our paper shows is that it's possible to select for cells that can be easily grown by using enzymes rather than by the tedious process of hand-dissecting them,...

UK Government proposes long-term strategy for science

...being - our science and skills. "While it would be easier to take the short term route - and fail to make the necessary investments for the future - we propose to take the longer term view, to choose science above many other spending priorities, and we will therefore propose a ten-year investment plan for s...

Tagging faulty genes with fluorescent nanodots

...e electronic and optical properties that make them easier to detect than conventional fluorescent tags used in biomedical research. The NIST team demonstrated that quantum dots give off signals that are 200 to 1,100 percent more intense than those from two types of conventional tags, and also are more stabl...

Lake restrictions make lakeshore property more valuable

...ncially, while protecting the environment, it's an easier sell." Whether or not more lakeshore communities will adopt restrictions to protect the value of their lakes and homes, the UW-Madison group says that more research should consider how humans may react to ecological change, as they are players both ...

Powerful machines are coming in small packages

...r are poised to make military and other equipment easier to power and carry. Scientists presented the lates...oduced a fuel cell that runs on methanol, which is easier to store and transport than hydrogen. "Basically, the device would be a chemical engine that you co...

Out-of-balance ecosystems play role in demise of amphibian populations

...ment of aquatic plants. Such a practice allows for easier boating, swimming and fishing, but by eliminating aquatic plants, the habitat becomes structurally barren. Herbicide use also aggravates the problem and produces chemical changes. Plant-derived oxygen is reduced, and herbicides also may have direct t...

Bighorn sheep threatened by climate change

...hat effects on populations from global warming are easier to detect in bighorn sheep than species of other large mammals that are more uniformly distributed over the landscape. "Other large mammals may shift north more gradually as a result of global warming, but that trend is harder to detect in the short ...

Asia's biodiversity vanishing into the marketplace

... across the region. "In many parts of Asia, it is easier to see animals in the markets than in the forest," said COP-7 delegate Dr Kent Redford, Director of WCS's Conservation Institute and originator of the "empty forest syndrome" concept, used to describe forests after hunters decimate their animal popul...

Fish, FRAMES and sticky chemicals net technology award for Pacific Northwest National Laboratory

...ing how chemicals change in the environment became easier and more accurate with the development of the PNNL chemical testing chamber, a new tool for understanding hard-to-measure chemical emissions. The chamber is the first system to precisely measure semi-volatiles, very sticky chemicals that remain in t...

Online calculator improves analysis of chemical data

...n process, MassSpectator saves time; makes it much easier to work with massive datasets such as those used to study the functions of proteins; and eliminates errors or bias that might be introduced by manually translating mass spectrometry peaks into final chemical results. For example, by using Mass Specta...

Hopkins researchers identify transplantation antigens among Sioux Indians

...ty compared to other populations, and it should be easier to find a match within their own group," Leffell adds. "We hope this knowledge will remove some barriers to donation within the tribes." The study was conducted as part of a series of workshops initiated in 1992 by members of the American Societ...
