Birth defects: 8 million annually worldwide

... providers to use simple diagnostic and preventive tools that are available. In the past, the toll of birth defects in these countries has been underestimated for a variety of reasons, the report authors say. These include poor, if any, health statistics; lack of birth defects surveillance or registries;...

Researchers unlock how cells determine their functions

.... "As a result, we can now use non-coding RNAs as tools to actively determine cell fate," Sauer said."Over the last few years, researchers have focused on how noncoding RNAs silence genes," said Anthony Carter, of the National Institute of General Medical Sciences, which partially funded the research. "Dr...

Technique makes it easier to see mouse embryo in all its glory

...vancements in imaging instrumentation and software tools are helping us understand the genetic basis of mammalian development in unprecedented clarity. It may seem hard to imagine, but putting embryology tutorials on an X-Box for eighth-grade biology students to study the genetic basis of development is al...

Sequencing our seas

... Microbial ecologists have had fairly rudimentary tools and techniques to bring to bear on their research to date, DeLong said. But now with the ability to sequence vast amounts of DNA in shorter time periods, the science is pressing forward. DeLong and his colleagues saw a unique opportunity for a "proo...

Wyoming cloud seeding experiment begins this month

... Microbial ecologists have had fairly rudimentary tools and techniques to bring to bear on their research to date, DeLong said. But now with the ability to sequence vast amounts of DNA in shorter time periods, the science is pressing forward. DeLong and his colleagues saw a unique opportunity for a "proo...

Vaccine provides 100 percent protection against avian flu virus in animal study

... Microbial ecologists have had fairly rudimentary tools and techniques to bring to bear on their research to date, DeLong said. But now with the ability to sequence vast amounts of DNA in shorter time periods, the science is pressing forward. DeLong and his colleagues saw a unique opportunity for a "proo...

Neurons find their place in the developing nervous system with the help of a sticky molecule

.... "Much work needs to be done, and the appropriate tools need to be developed to do this work," said O'Leary, "but we feel that these studies will eventually provide insight into neurological disorders that have their basis in malpositioning of neurons." ...

Researchers map of genetic variations implicated in disease

...r increasing rate, we are developing the necessary tools and sample collections to make a real difference to the study, diagnosis and, we hope, treatment of diseases such as TB, coronary heart disease, diabetes and rheumatoid arthritis." The MHC Haplotype Project is creating a public resource to assist th...

Climate change: The rice genome to the rescue

... is already providing researchers with some of the tools they need to help poor rice farmers and consumers avoid the worst effects of the problem. The new knowledge generated by the sequencing effort is allowing scientists to both develop new rice varieties faster and with the specific characteristics nee...

Pleasing plant shapes explained by new computer model

...e between biology and computer science and how the tools of one discipline can be used to answer questions in another," said Prusinkiewicz, who specializes in computer simulations and visualizations in plant biology. " ...

New RNAi tools enable systematic studies of gene function

...this unique public-private effort, we now have new tools to enable the entire research community to realize...s the spectrum of biomedicine, there is a need for tools that can be applied to diverse cell types. This is particularly true in cancer research," said Bill ...

Environmental metagenomics diagnosing extreme environments, tapping opportunities for clean energy

...duce biofuels. "Through DNA sequencing and the tools of molecular biology we can generate diagnostic fingerprints, Environmental Genomic Tags or EGTs, that provide a metabolic profile of any environment, even such extreme conditions as acid mine drainage," says Edward M. Rubin, DOE JGI Director. "We c...

DNA conclusive yet still controversial, Carnegie Mellon professor says

...r current research is focused on using statistical tools to understand the workings of the human genome and...'s primary research goal is to develop statistical tools for finding associations between patterns of genetic variation and complex disease. ...

Hooked on fishing, and we're heading for the bottom, says scientist

...hes, and skirting existing laws through the use of tools such as flags of convenience. And, he says, public policy on marine fish conservation issues is distorted by the fact that most governments view fishing companies, and not their citizens, who actually are the true owners of the resources, as their ma...

Clues to breast cancer hidden inside stem cells

...ce. The hope is that they might also become useful tools to test new drugs. "People have long suspected there should be a stem cell population in the human breast gland," said Sigurdsson who is part of the ESF-funded team led by Thorarinn Gudjonsson. A 'virgin' breast, before pregnancy, is very differen...

Nanotechnology may find disease before it starts

...ages produced by one of the most common diagnostic tools used in doctors' offices ?the ultrasound machine. In laboratory experiments on mice, scientists found that nano-sized particles injected into the animals improved the resulting images. This study is one of the first reports showing that ultrasound c...

Spring migration of pink-footed geese under threat

...to climate change. According to Klaassen: "We need tools to predict how organisms will respond to local and global changes, and such tools would be particularly useful if they could take into account adaptive behaviour. In the case of migr...

Researchers release new variety of asparagus

...urrent activity for our research is to incorporate tools from molecular genetics to improve the efficiency of asparagus breeding." Asparagus, which is a Greek word meaning stalk or shoot, grows best in sandy, well-drained soils. The plant can be productive for 15 years or more. Asparagus spears grow from...

Warbling whales speak a language all their own

...d co-authors John Buck and Peter Tyack applied the tools of information theory--a mathematical study of data encoding and transmission--to analyze the complex patterns of moans, cries, and chirps in the whales' songs for clues to the information being conveyed. Buck is an electrical engineer who specialize...
