Extracting Plant DNA From Grasshopper Guts Improves Understanding Of Plant-insect Interactions
2014-02-06 14:12:58

[ Watch the Video: Demonstration of Grasshopper Dissection ] American Journal of Botany Grasshoppers may be small, but the damages they are causing to the US agriculture industry are anything but. Every year, they feed on crops and on rangelands needed for raising livestock, costing landowners millions of dollars. Although they pose a major threat, grasshopper populations play a positive role in cycling nutrients from decomposing plant matter back into the soil. A new method to...

Environment, Lifestyle Factors Determines Changes In Pain Sensitivity
2014-02-05 09:12:41

Ranjini Raghunath for redOrbit.com - Your Universe Online The way you react to pain keeps changing throughout your lifetime, influenced by lifestyle and environmental factors, a new study carried out by researchers at King’s College London suggests. The study identified genetic changes that determine how different people – even identical twins -- react to pain differently. The results from the study could help scientists understand how pain sensitivity differs in individuals, and...

DNA Breakthroughs Welcome, But Americans Still Have Concerns
2014-02-05 06:35:12

[ Watch the Video: What Do People Really Think About DNA Research? ] April Flowers for redOrbit.com - Your Universe Online A new poll from the Huffington Post and YouGov finds that although most Americans are excited by the possibility of the scientific breakthroughs made possible by DNA research, many of them worry that research could go too far — and the scientists could begin "playing God." The possibility that DNA research could create major scientific and medical breakthroughs...

Primitive Artificial Cells Turned Into Complex Biological Materials
2014-02-04 15:22:51

University of Southern Denmark It is a big dream in science: To start from scratch with simple artificial microscopic building blocks and end up with something much more complex: living systems, novel computers or every-day materials. For decades scientists have pursued the dream of creating artificial building blocks that can self-assemble in large numbers and reassemble to take on new tasks or to remedy defects. Now researchers from University of Southern Denmark have taken a step...

How Does A Shape-shifting DNA-repair Machine Fight Cancer?
2014-02-04 12:27:58

Lawrence Berkeley National Laboratory Berkeley Lab’s Advanced Light Source reveals inner-workings of essential protein found throughout life. Maybe you’ve seen the movies or played with toy Transformers, those shape-shifting machines that morph in response to whatever challenge they face. It turns out that DNA-repair machines in your cells use a similar approach to fight cancer and other diseases, according to research led by scientists from the U.S. Department of Energy’s...

DNA Methylation May Increase Cancer Risk As We Age
2014-02-04 05:01:25

redOrbit Staff & Wire Reports - Your Universe Online Age-related changes in a biochemical process known as DNA methylation could be responsible for the increased risk of cancer in older men and women, according to research appearing in the latest edition of the journal Carcinogenesis. While medical experts have long known that the aging process is a leading risk factor for the development of several different types of cancer, the exact reasons for that phenomenon have remained...

New Microscopy Method Could Spot Dozens Of Distinct Types Of Biomolecules Simultaneously
2014-02-03 09:49:50

Wyss Institute for Biologically Inspired Engineering at Harvard A new microscopy method could enable scientists to generate snapshots of dozens of different biomolecules at once in a single human cell, a team from the Wyss Institute of Biologically Inspired Engineering at Harvard University reported Sunday in Nature Methods. Such images could shed light on complex cellular pathways and potentially lead to new ways to diagnose disease, track its prognosis, or monitor the effectiveness of...

Brief Introduction To DNA Probes
2014-01-12 00:00:00

DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...

Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though recent research has proven this to not be strictly correct. It is not a human pathogen although...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
