Chernobyl: The true scale of the accident

...targeting and funding shortages. * Structural elements of the sarcophagus built to contain the damaged reactor have degraded, posing a risk of collapse and the release of radioactive dust; * A comprehensive plan to dispose of tons of high-level radioactive waste at and around the Chernobyl NPP site,...

Many smokers fail to quit after cancer diagnosis

...rgeted interventions have been designed to combine elements of behavioral therapy and pharmacotherapy, but only a few studies exist assessing their efficacy. Another shortfall is that these studies, with one exception, target smokers with smoking-related cancers. The common finding was that the healthcare pro...

Female butterflies go for sparkle -- not size -- when choosing to mate

... to mate. The UB researchers altered wing-pattern elements through carefully painting the wings or by pairing males displaying traits of different size and color. They then tested female preference for wing size, eyespot size, quantity of eyespots on the wing, eyespot and pupil color, and pupil reflectivity....

New book expands biological classifications to account for 'alien' life

...rom Earth that likely would be based on silicon or elements other than the carbon-hydrogen-oxygen-nitrogen mix...d away from Earth, at least some could be based on elements such as silicon, perhaps in combination with carbon. Because environments are far colder on moons an...

Techniques available to detect soil that inhibits destructive soybean pest

...g treatments to eliminate soil organisms and other elements that inhibit nematode development. Another confirmation technique was to add suppressive soil to soils conducive to nematode development. The researchers also were able to document reduced nematode reproduction, population density, and whether certai...

NHGRI expands effort to revolutionize sequencing technologies

... $100,000. Both approaches have many complementary elements that integrate biochemistry, chemistry and physics with engineering to enhance the whole effort to develop the next generation of DNA sequencing and analysis technologies. "It is very important that we encourage and support the variety of sequencing...

Micro RNAs play role in egg making

...e eggs. MiRNAs silence genes by binding to genetic elements called messenger RNA and preventing them from making new proteins -- the molecules primarily responsible for cell activities. While previous research has identified some miRNA targets, investigators haven't yet seen how they impact developmental pro...

Drugs from the deep blue

...e are related to fats and proteins; others include elements such as bromine, sometimes bonded into improbable structures. "It's a rich, complex and edited chemical library," Molinski said. "They're really fascinating little jewels made by niche creatures." As well as being largely unexplored, the chemistry ...

Making plant cells work like miniature factories

...enior chemist who specializes in identifying trace elements using inductively couple plasma-mass spectrometry, and associate scientist and ISU chemistry professor Ethan Badman, who specializes in mass spectrometry and gas-phase methods of analysis for biological molecules. Rounding out the team is Basil Nikol...

Breast tumors in mice eradicated using cancer vaccine

...er ten years ago. "It took a while to dissect what elements of an immune response were best able to cause the rejection of established tumors," she says. "But in the last couple of years it has paid off and we are very excited to see the technology finally being tested in cancer patients. The dream of the can...

Acid water in East Java threatens biodiversity and local welfare

...dity - also plays an important role in this. Other elements such as fluorine, in the form of fluoride, form a direct threat for public health. The levels are not only alarmingly high in the river water but also in the groundwater and drinking water wells. Biodiversity Within the large project scientists ...

Retina adapts to seek the unexpected, ignore the commonplace

...h as forests or fields of grass with many vertical elements but only rare horizontal features, the retina adjusts to suppress the routine vertical features while highlighting the singular horizontal elements. Meister and his co-authors examined neural signals in retinal ganglion cells, which convey visual im...

Life's origins were easier than was thought

...he first nucleic acid chains, which were the first elements able to self-replicate. According to one of the more accepted theories, these molecules were ribonucleic acid (RNA) chains, a molecule that is practically identical to DNA and that today has the secondary role in cells of copying information stored i...

Virginia Tech, Nanjing Institute researchers discover half-billion year-old fossils

...at many Ediacara organisms were built of tube-like elements and are only distantly related to living animals. ...t direct observation of the hypothesized tube-like elements has been difficult because such tubes tend to be deflated and squashed prior to their preservation i...

Researchers find molecule that inhibits regrowth of spinal nerve cells

Hanging baskets of sex and death help fruit growers

...ispenser is designed to protect the virus from the elements and also includes a strong source of codling moth pheromone. The pheromone draws in the moth hoping for a sexual encounter and the insect leaves frustrated but covered in the virus which it then passes on to other moths when it does manage to have an...

Temperature regulates circadian clock in zebrafish

...tterns. While it's well known that circadian clock elements sense and respond to light cycles, much less is known about how daily temperature cycles affect the clock's timing mechanism in vertebrates. In the open-access journal PLoS Biology , Kajori Lahiri, Nicholas Foulkes, and their colleagues study tempe...
