A more powerful and efficient engine for rice: the C3-C4 challenge

...s poor. "Frankly, we have almost exhausted the traditional methods of increasing rice production, especially considering the environmental challenges we face such as climate change," IRRI Director General Robert Zeigler said. "This generation must work to assure food security not only for ourselves, but for ...

Mitochondrial DNA sequencing tool updated

...ence the mitochondrial genome much faster than the traditional manual and automated strategies. Just as importantly, like an iPod to music lover, the chip served as the broad technological platform for laboratories to customize arrays more attuned to their research interests. In 2004, Dr. Anirban Maitra and h...

For Stanford scientists, RNAi gene therapy takes two steps forward, one step back

...that we need to proceed cautiously," Kay said. In traditional gene therapy the inserted DNA produces a gene to replace one that carries a mutation. In hemophilia, for example, the inserted gene makes a protein that is missing in the blood of people with the disease. RNAi gene therapy has the opposite effect. Th...

Cycles of cell death, proliferation key to liver cancer

...t or cure through chemotherapy, radiation or other traditional cancer treatments. "We now understand development of liver cancer in mice. Since inflammation drives both damage and regeneration in liver tissue, it is the repeating cycle of damage, inflammation and regeneration that leads to liver cancer," said ...

Radiation-killed bacteria vaccine induces broad immune response in mice

...but also the body's innate immune system. However, traditional ways of making vaccines--either by killing disease-causing agents with heat, chemicals or by weakening (attenuating) live pathogens--have characteristic shortcomings. For example, heat- and chemical-killed vaccines, while safe and relatively easy to ...

Mass. General study finds potential ovarian cancer stem cells

...l these stem-like cancer cells may be resistant to traditional chemotherapy and could be responsible for the ultimately fatal drug-resistant recurrence that is characteristic of ovarian cancer," says Paul Szotek, MD, of the MGH Pediatric Surgical Research Laboratories, first author of the PNAS report. "We belie...

Virtual realities against pain

...t the requirements of an ideal distractor than the traditional distraction methods such as watching a film or playing a simple computer game. The ADTs simulate real-life situations, and the possibilities are infinite. For example, until now users could choose between taking a flight, driving, downhill skiing, ...

Bubbles go high-tech to fight tumors

...e this developmental technique to the clinic. In traditional embolotherapy techniques, the so-called cork that doctors use to block the blood flow---called an emboli---is solid. For instance, it could be a blood clot or a gel of some kind. A major difficulty with these approaches is restricting the emboli to t...

Brazil creates buffer zone around coral reefs off Atlantic coast

...nue carrying out their means of livelihood through traditional fishing and eco-tourism activities," said Guilherme Dutra, director of CI-Brazil for the marine program. The Abrolhos region, located off the coastal town of Caravelas in the far south of Bahia, northeast Brazil, is home to mangrove forests and res...

How ancient whales lost their legs, got sleek and conquered the oceans

...es. Researchers say the findings tend to support traditional evolutionary theory, a la Charles Darwin, that says minor changes over vast expanses of time add up to big changes. And while Sonic hedgehog's role in the evolution of hind limbs in ancient whales is becoming apparent, it is still not fully defined. ...

Completed genome set to transform the cow

...in 50 years as we have over the last 8000 years of traditional farming." Cattle geneticists will use the bovine genome as a template to highlight genetic variation within and between cattle breeds, and between cattle and other mammal species. The head of bioinformatics research at CSIRO Livestock Industrie...

When the going gets tough, slime molds start synthesizing

...Molecular Biology (MRC) in Cambridge, England, use traditional and computer-based methods to show how Dictyostelium synthesizes the chemical signal called DIF-1, short for Differentiation Inducing Factor, required for this developmental transformation. The collaboration, explains co-senior author Joe Noel, Ph....

Smooth sailing: 'cruise ship virus' tackled by UH, Baylor College of Medicine

...g Norwalk is that it is very hard to diagnose with traditional methods. "The current tests take a long time," Ruchhoeft said. "If we can build a diagnostic tool that mimics something like the pregnancy test in speed and ease of use, we could create a platform for rapid detection of this virus and other path...

Brighter future for giant panda?

...station. However, given the variable accuracy of traditional ecological population recording methods, scientists from Cardiff's School of Biosciences working with a team in China used a novel approach to accurately estimate population size. The results are published in the international journal Current Biolog...

Study supports 'urgent' need for worldwide ban on lead-based paint

...orted consumer products, including candy, folk and traditional medications, ceramic dinnerware and metallic toys and trinkets. In a two-year study headed by Scott Clark, PhD, the UC-led research team found that more than 75 percent of the consumer paint tested from countries without controls--including India,...

Computational analysis shows that plant hormones often go it alone

...resets many systems within the plant." Combining traditional biological approaches with computational analysis will move plant biologists closer to answering the age-old question of how plants grow, the Salk researchers predict. "Microarrays are very useful for those of us studying physiology and development. ...

Wild vs. lab rodent comparison supports hygiene hypothesis

...dying human disease and allergies that complements traditional scientific studies. "Laboratory rodents live in a virtually germ- and parasite-free environment, and they receive extensive medical care -- conditions that are comparable to what humans living in Westernized, hygienic societies experience," said Wil...

Agriculture and tropical conservation: rethinking old ideas

...t that's not the case if the intervening areas are traditional "agroforests"---farms where fruit and timber trees share space with other crops, Vandermeer said. "That's the kind of agriculture that's friendly to biodiversity, and that's the kind of agriculture that peasant farmers actually do." Vandermeer and ...

New flood-tolerant rice offers relief for world's poorest farmers

...the International Rice Research Institute."Several traditional rice varieties have exhibited a greatertolerance to submergence, but attempts to breed that tolerance intocommercially viable rice failed to generate successful varieties. "We're especially pleased that we have been able to use the latestadvances i...

Lost in thought: Brain research

...in a broader perspective, one that veers away from traditional western thought, with its emphasis on self-control and for which 'someone is always minding the store,' and toward more eastern perspectives, in which the 'self must be abandoned in order to fully engage with the outside world.'"
