New technologies coming too fast for Indian farmers

... 'De-skilling' While Bt seed exacerbates the problem by creating yet another option, the farming troubles predate its introduction. In the late 1990s, there was an epidemic of farmer suicide in the Warangal District. Many farmers are deeply in debt and have been for generations. Stone's study shows...

Antifungal drug kills TB bug

...eases in the number of TB infections. However, the problem is most acute in Africa and Asia where HIV/AIDS is also most prolific and a shortage of traditional TB medicines and problems with patient compliance has led to the emergence of drug-resistant strains of the disease. "There were only ever a limite...

The authors point out that the basic problem of huge excess effort in lobster fishing is characteristic of other aspects of fishing industries around the world--including shrimp and tuna longline industries that expend much more effort than needed to obtain optimal yields, while threatening tur...

Scientists clone mice from adult skin stem cells

... make embryonic stem cell lines, circumventing the problem of immune rejection. Such stem cells might also be used to study a variety of different diseases, for which patient tissue is often hard to come by. "There are many diseases, such as liver, pancreatic and neurodegenerative disorders where rese...

Grape expectations for healthier wine

...actions in some people. Wine-makers have a similar problem in that the sulphites added to wines to prolong their shelf-life and allow them to age can make their wines unpalatable to some drinkers. Francisco Artes-Hernandez and his team at the Technical University of Cartagena in Spain compared several dif...

Scientists use nanoparticle to discover disease-causing proteins

...urnal's news publication Chemical Biology. "The problem with the current method of using proteomics - protein profiling - is that we use very small sample amounts so sensitive that we can't effectively use existing technologies to study them," Tao said. "In addition, to study a specific protein and its fu...

Protein discovery targets antibiotic-resistant bacteria

...ated to that responsible for typhoid fever ?a huge problem in less developed countries ?the model being developed at Queen’s could potentially be a target for treating typhoid as well. The underlying goal is to control, if not clear, the infection. “It’s basic science that we are doing, but we’re using th...

Large size crucial for Amazon forest reserves

...Research Center. "With a handle on the detection problem it is much easier to understand real species occurrence", said Nichols, "and looking at occurrence through time, one understands the dynamics of species faced by forest destruction". Some vanish because they don't survive in a given site, others bec...

Researchers create artificial enzyme that mimics the body's internal engine

...odel in a slow and continuous way. They solved the problem by attaching the model to a liquid crystalline film on a gold electrode, which provided a nonstop supply of electrons to the model as it transformed oxygen molecules into water-a process called steady turnover. "The biochemists that study the enzy...

Illuminating the dark side of plants

Plant poisoning is a significant problem around the world. In the United States, exposures to plant toxins account for approximately ten percent of the annual calls to the nation's Poison Control Centers. Responding to the need for a useful guide to the harmful potential of plants, Handboo...

No carrier necessary: This drug delivers itself

The problem of efficiently delivering drugs, especially those that are hydrophobic or water-repellant, to tumors or other disease sites has long challenged scientists to develop innovative delivery systems that keep these drugs intact until reaching their target...

Cancer tip -- Nanoparticles can damage DNA, increase cancer risk

...and ultimately increase the risk of cancer." One problem is that, while it’s clear that some nanoparticles can be more toxic than others, there’s not enough data as yet to determine the most dangerous types. "A lot is unknown about nanoparticle function, but clearly both size and composition are impor...

OHSU lab finds meth receptor that could lead to therapy

...tations of its abuse. "Meth addiction is such a problem and we have nothing to treat it with except group support therapy," Grandy said. "Now we have a new target, something completely different to focus on, and we think that offers a lot of hope." Grandy is actively collaborating with Thomas Scanlan, ...
