Researchers at the Stanford University School of Medicine have discovered that males of the laboratory roundworm secrete signaling molecules that significantly shorten the lifespan of the opposite sex. The scientists speculate that, if carried out after reproduction, this "male-induced demise" could serve to conserve precious resources for a male's offspring or to decrease the supply of mates for other males. For several years, it's been known that the presence of some male worms and...

Forensics May Rely On 'Microbial Clock' To Establish Time Of Death
2013-09-25 07:56:45

[ Watch the Video: Time Of Death Determined By Microbial Clock ] April Flowers for redOrbit.com - Your Universe Online Forensic scientists already have an extensive toolbox of techniques for determining the time of death in cases involving human corpses, but an intriguing new study led by the University of Colorado may just give them a new one. The findings, published in the new online science and biomedical journal eLIFE, describe a microbial clock that is essentially the lock-step...

The pale cyst nematode, Globodera pallida, is one bad roundworm. Unchecked, the pest burrows into potato roots to feed, obstructing nutrients and causing stunted growth, wilted leaves and other symptoms that can eventually kill the plant. Severe infestations can cause tuber yield losses of up to 80 percent. Now, however, U.S. Department of Agriculture (USDA) and cooperating scientists are evaluating new ways to control G. pallida using naturally occurring chemicals called egg-hatching...

Molecular Key To Exhaustion Following Sleep Deprivation Found By Researchers
2013-03-07 15:37:28

University of Pennsylvania School of Medicine It happens to everyone: You stay up late one night to finish an assignment, and the next day, you're exhausted. Humans aren't unique in that; all animals need sleep, and if they don't get it, they must make it up. The biological term for that pay-the-piper behavior is "sleep homeostasis," and now, thanks to a research team at the Perelman School of Medicine, University of Pennsylvania, one of the molecular players in this process has been...

Artificial Intelligence Finds Mutations Faster
2012-08-20 05:57:57

Michael Harper for redOrbit.com — Your Universe Online In order to fully understand some diseases – how they work, how they spread, response to drugs, etc – researchers have been employing some of the world´s tiniest animals, such as the multicellular fruit fly, nematode, or zebra fish. While this examination by itself is useful, these researchers can make real progress in their studies if they can examine a multitude of animals in order to detect any mutation among...

Possible Tool To Study Aging From “Selfish” DNA In Animal Mitochondria
2012-08-10 09:14:10

Researchers at Oregon State University have discovered, for the first time in any animal species, a type of “selfish” mitochondrial DNA that is actually hurting the organism and lessening its chance to survive — and bears a strong similarity to some damage done to human cells as they age. The findings, just published in the journal PLoS One, are a biological oddity previously unknown in animals. But they may also provide an important new tool to study human aging,...

The lowly and simple roundworm may be the ideal laboratory model to learn more about the complex processes involved in repairing wounds and could eventually allow scientists to improve the body's response to healing skin wounds, a serious problem in diabetics and the elderly. That's the conclusion of biologists at the University of California, San Diego who have discovered genes in the laboratory roundworm C. elegans that signal the presence of surface wounds and trigger another series of...

San Francisco State University study published by the journal Genetics Compared to most other cells in an organism, sperm undergo a radical transformation to become compact and mobile delivery systems for paternal DNA. Even though sperm looks and moves quite differently across species, SF State researcher Diana Chu and colleagues now say that there are at least a few key enzymes that are critical for sperm development and mobility in species as different as mice and nematode worms. The...

Study shows that selection pressures imposed by predator fungi have shaped escape behavior in microscopic worms Escape responses are some of the most studied behaviors by neurobiologists who want to understand how the brain processes sensory information. The ability to evade predators plays a vital role in the process of natural selection. Animals explore their environment to find food, find mates and locate new habitats, and have developed distinct escape responses to avoid predators,...

The development of identical egg laying organs of two nematode species is regulated by different signaling pathways Changes in a short protein domain can alter a whole signaling network involved in organ development"“ this is the key result of a comparative study of the development of the egg laying organ in two species of nematodes. However, the outward appearance of the organ remains the same in both species. The study provides support for the theory of developmental systems drift...

Golden Nematode, Globodera rostochiensis
2014-01-12 00:00:00

The Golden Nematode (Globodera rostochiensis), also known as the golden eelworm or yellow potato cyst nematode, is a species of plant pathogenic nematode originally stemming from the Andes Mountains of South America. It was first discovered in Germany in 1913, believed to have arrived in Europe with imported potatoes sometime in the 19th century. It was first discovered in the US in 1941, in Canada in the 60s, and in Mexico in the 70s. It has also been found throughout Asia, Africa and...
