Chernobyl: The true scale of the accident

... find better ways both to inform the public and to overcome the lack of credibility that hampered previous efforts. Even though accurate information has been available for years, either it has not reached those who need it or people do not trust and accept the information and do not act upon it, according to ...

Kenya halts first field trials of GM maize

... will continue until we help African maize farmers overcome the pest". Stem borers destroy up to 12 per cent of maize growing in Kenya, amounting to US$76 million in lost harvests per year. The IRMA project, which began six years ago, aims to develop both conventional and GM maize varieties to resist the pe...

Getting close to nature is good for you

...ting beyond the individual. Such projects can help overcome social isolation, develop skills, and improve employment prospects, as well as provide the known benefits associated with exercise. Although initial research has been promising, the UK needs robust health impact assessments of wildlife projects to d...

New molecule may aid in production of biofuels and fungi-resistant plants

...ins in the chitin molecule. How exactly chitinases overcome these challenges has been unclear until now. Interested in learning more about how the breakdown of chitin occurs, Dr. Eijsink and his colleagues investigated chitin degradation by the soil bacterium Serratia marcescens. They discovered that in addi...

Gene therapy for muscular dystrophy fixes frail muscle cells in animal model, Stanford study finds

.... "I think our approach has a lot of potential to overcome issues that have slowed the field of gene therapy," Calos said. Calos said her approach has two advantages: one is that in her method the gene gets inserted directly into the cell's own DNA, which is why the correction is permanent. In some other me...

Why Christmas trees are not extinct

...dest trees, bristlecone pines. So how did conifers overcome the handicap of short pipes? Scientists already knew that the valves between water pipes or conduits are far different in conifers than in angiosperms, or flowering trees, but they did not know how that difference affected water flow. In the new st...

Report focuses on challenges to unlocking future promise of vaccines

...oved. The report also provides recommendations to overcome obstacles that prevent the best use of existing vaccines. "Vaccines are available for some diseases that continue to plague humans, but not for others. Even when a licensed vaccine is available for a given disease, numerous barriers can block its u...

Plant defenses prompt bacterial countermeasure in the form of 'island' DNA excision

...ears by excising specific genes from its genome to overcome the host plant's specific defenses. Throughout evolution ?in the wild and in crops cultivated by humans ?plants have developed systems for resisting the attack of microbial pathogens, while these microbes themselves have depended on their ability to...

How Fruitflies Know It's Time for Lunch

... and external signals. How hungry must flies be to overcome taste aversion? How do the competing neural networks of taste and hunger signals decide whether the fly will eat? Future studies pairing behavioral and genetic analysis may begin to reveal answers to these open questions. ...

Recreating 'Flowers for Algernon' with a happy ending

...hing for a safe drug that would zero in on Ras and overcome its hyperactivity without causing harmful side effects over long-term use. "It became something of a Quixotic quest -- an impossible dream," Silva admitted. "We thought, 'Wouldn't it be nice to find a drug that is already FDA-approved, safe for lif...

Engineered Stem Cells Show Promise For Sneaking Drugs Into The Brain

...r up to three months. One hurdle that needs to be overcome before such a technique could be attempted in human patients, says Svendsen, is developing a method to switch transplanted cells on or off and thus control their drug delivery capabilities. Working with engineered cells in culture, the Wisconsin grou...

Anyway you slice it, tomatoes cut through drought with new gene

...arve out a huge amount of food production. To overcome food shortages, the authors suggest, "it will be necessary to increase the productivity of land already under cultivation and to regain the use of arable land lost to scarce water supplies." Hirschi and Gaxiola worked with Dr. Sunghun Park, also ...

Researchers uncover mechanisms of estrogen in promoting cell death in breast cancer

...ts raise the possibility that estrogen therapy may overcome resistance to certain breast cancer hormonal therapies. The study appears in the December 7 issue of the Journal of the National Cancer Institute. When cancer treatments such as chemotherapy or hormonal therapy fail to cause tumor regression, ...

Study finds that nutritionally enhanced rice reduces iron deficiency

...ast, we relied on supplements and fortification to overcome vitamin and mineral deficiencies," said Howarth Bouis, director of HarvestPlus. "Now we know that biofortification also works, giving us an additional tool in this crucial battle." The United Nations and other donors spend millions of dollars a yea...

Depression model leaves mice with molecular scar

...cular activators attach themselves to the gene and overcome the silencer molecules. Imipramine turned off an enzyme (Hdac5) that degrades the activators, allowing them to accumulate. "The molecular scar induced by chronic stress in the hippocampus, and perhaps elsewhere in the brain, can't be easily reverse...

Ancient DNA helps UF researchers unearth potential hemophilia therapy

... to use the transposon and trying to find a way to overcome the immune attack when performing gene therapy on adult animals. "I don't think the research is done," Mah said. "But this is definitely a step forward for hemophilia gene therapy." ...

Simple idea to dramatically improve dengue vaccinations

...sly at different locations on the body ?could help overcome immunodominance by taking advantage of the relative isolation of lymph nodes throughout the body. Each person has hundreds of lymph nodes. Deem believes vaccinations at four different sites, served by four different lymph nodes, could allow the body ...

Climate change: The rice genome to the rescue

...d's poor live. The workshop was informed that, to overcome many of the climate change–related problems facing rice production in Asia ?and continue to meet the demand for rice in the region ?yields will have to double over the next 50 years. Research has confirmed that global warming will make rice crops les...

Scientists a step closer to protecting world's most important crop

...its proteins into the plant's own cells where they overcome the plant's defences allowing a full scale invasion by the fungus. Until now it's not been known how the fungus delivers that weaponry, but researchers from the School of Biosciences have identified a single gene that appears to be important in the ...
