Snoozing worms help Penn researchers explain the evolution of sleep

Researchers report that the round worm has a sleep-like state, joining most of the animal kingdom in displaying this physiology. This research has implications for explaining the evolution and purpose of sleep and sleep-like states in animals, as well as identifying drug targets for sleep disorders.

1. Researchers invent system to control and quarantine worms attacking computer networks
   02-08-2007 · EurekAlert!
   A new anti-worm technology developed by Penn State researchers can not only identify and contain worms milliseconds after a cyber attack, but can also release the information if the quarantine turns out to be unwarranted.

2. Researchers plumb mysteries of Antarctic Mountains
   07-20-2007 · EurekAlert!
   The 3,000-kilometer-long Transantarctic Mountains are a dominant feature of the Antarctic continent, yet up to now scientists have been unable to adequately explain how they formed. In a new study, geologists report that the mountains appear to be the remnant edge of a gigantic high plateau that began stretching and thinning some 105 million years ago, leaving the peaks curving along the edge of a great plain. This study revolutionizes thinking about Antarctica’s evolution.

3. Bungee-powered backpack can lighten your load, University of Pennsylvania researcher says
   12-20-2006 · EurekAlert!
   Penn researchers have announced details for a suspended-load ergonomic backpack that reduces the force of a backpack's load on the wearer by 86 percent, allowing wearers to run far more comfortably with heavy loads. The backpack was created with soldiers and emergency workers in mind and could prevent the sort of muscle and joint injuries associated with running while carrying heavy items.

4. The origin of the brain lies in a worm
   04-20-2007 · EurekAlert!
   Researchers from the European Molecular Biology Laboratory in Heidelberg now reveal that the vertebrate nervous system is probably much older than expected. The study, which is published in the current issue of Cell, suggests that the last common ancestor of vertebrates, insects and worms already had a centralised nervous system resembling that of vertebrates today.

6. Iron banded worms drying out of blood could be linked to Parkinson's and Alzheimer's
   02-09-2008 · EurekAlert!
   Researchers at the University of Warwick and the Indian Institute of Technology Kanpur have discovered that the mechanism that we rely on to transport iron safely through our blood can collapse into a state which grows long worm-like "fibrils" banded by lines of iron rust. This process could provide the first insight into how iron gets deposited in the brain to cause some forms of Parkinson's & Alzheimer's and Huntington's diseases.

   12-22-2006 · EurekAlert!
   The giraffe's elongated neck has long been used in textbooks as an illustration of evolution by natural selection, but this common example has received very little experimental attention. In the January issue of the American Naturalist, researchers tested whether foraging competition with shorter herbivores could explain why giraffes feed mostly on leaves high in trees, despite being able to feed at lower levels as well.

   A benign virus previously used as a marker in tracing human migration may be unreliable, according to researchers at Penn State. Results of this study also suggest that some viruses might be undergoing much higher rates of evolution than previously thought.

10. Gene that makes people 'early to bed and early to rise' demystified
    01-11-2007 · EurekAlert!
    The recent discovery that a mutant "clock" gene made some people "early to bed and early to rise," a condition known as familial advanced sleep phase syndrome (FASPS), offered one of the first glimpses into the genetic basis of sleep in humans. Now, researchers report in the Jan. 12, 2007, issue of the journal Cell, published by Cell Press, new evidence that helps to explain just how their bodies' natural alarm clocks get set to such an early wake-up time.
