Humans are not alone in suffering the ravages of aging. Cockroaches endure it, too.
Case Western Reserve University researchers reported in the Journal of Experimental Biology that as the roachs life wanes between 60-65 weeks after the onset of adulthood, and the cockroach slows down, experiences stiff joints and has problems climbing and a decreased spontaneous fleeing response. Death comes shortly after the onset of these movement problems.
Angela Ridgel, a post doctoral fellow at Case, was the lead author on the National Institute of Health-funded study, "Effects of aging on behavior and leg kinematics during locomotion in two species of cockroaches." Her research looked at walking, climbing and righting behavior in the roach species, Blaberus discoidalis. She wrote the paper with Roy Ritzmann, professor of biology, and Paul Schaefer, a former Case graduate student who studied escape behavior in Periplaneta americana and contributed information about the roachs central nervous system and escape behavior.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
