Researchers using Arecibo Telescope discover never-before-seen pulsar blasts in Crab Nebula
Astronomers and physicists using the Cornell-managed Arecibo Telescope in Puerto Rico have discovered radio interpulses from the Crab Nebula pulsar that feature never-before-seen radio emission spectra. This leads scientists to speculate this could be the first cosmic object with a third magnetic pole. view more (2007-01-09)
LIGO observations probe the dynamics of the crab pulsar
The search for gravitational waves has revealed new information about the core of one of the most famous objects in the sky: the Crab Pulsar in the Crab Nebula. view more (2008-06-03)
First view of a newborn millisecond pulsar?
Combining Hubble Space Telescope images with radio observations has revealed a highly unusual system consisting of a fast spinning pulsar and a bloated red companion star. The existence of the system is something of a mystery - the best explanation so far is that we have our first view of a millisecond pulsar just after it has been `spun up` by... view more...

A young pulsar shows its hand
A small, dense object only twelve miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years. view more (2009-04-06)
White Dwarf Pulses Like a Pulsar
New observations from Suzaku, a joint Japanese Aerospace Exploration Agency (JAXA) and NASA X-ray observatory, have challenged scientists' conventional understanding of white dwarfs. Observers had believed white dwarfs were inert stellar corpses that slowly cool and fade away, but the new data tell a completely different story. view more (2008-01-03)
20 Thousand Leagues Under The Sea"¦ And Up Into Space
What could an astronaut learn from a crab? In the ocean, detecting depth is crucial. If an animal swims too deep it may be crushed by the immense pressure it encounters. Fortunately for the crab it is able to detect pressure using its balance system and, by exploiting the sensitivity of this system, it may be possible to compensate for the... view more...

Diffuse ways to get rid of ammonia?
Ammonia is a problem. All animal cells produce it, but how do they get rid of it? New research by Dr Dirk Weihrauch (University of Illinois at Chicago) to be presented on Wednesday 2 April (session A2.2) suggests that the crab may have evolved a rather novel solution. For us mammals, the key to getting rid of waste ammonia is to detoxify it into... view more... (2003-03-26)
Where there is muck, there are hermits
The accumulation of manmade rubbish on our beaches is proving to be a surprising benefit for one animal - the hermit crab has a new source of mobile homes. view more (2002-12-04)
Part-time pulsar yields new insight into inner workings of cosmic clocks
Astronomers using the 76-m Lovell radio telescope at the University of Manchester's Jodrell Bank Observatory have discovered a very strange pulsar that helps explain how pulsars act as 'cosmic clocks' and confirms theories put forward 37 years ago to explain the way in which pulsars emit their regular beams of radio waves-considered to be one of... view more...

Decline of Shorebird Linked to Bait Use of Horseshoe Crabs
Declining numbers of a shorebird called the red knot have been linked to bait use of horseshoe crabs. view more (2009-02-18)
Smithsonian identifies invasive crab species in Panama Canal expansion area
A Smithsonian scientist and colleague report that a potentially harmful, invasive crab species that has spread to several countries is now established and reproducing in Panama. view more (2007-09-20)
Horseshoe crab decline threatens shorebird species
Researchers from Virginia Tech and the New Jersey Division of Fish and Wildlife have documented a reduction in the number of red knot birds throughout the Delaware Bay tied to a decline in horseshoe crabs. view more (2006-02-22)
New 150 Million-Year-Old Crab Species Discovered
Researchers from Kent State University and the University of Bucharest, Romania, have discovered a new primitive crab species Cycloprosopon dobrogea in eastern Romania. Previously unexamined, these ancient crabs from the Prosopidae family existed more than 150 million years ago during the Jurassic period. view more (2007-10-18)
UAB research could boost coastal economics with crustacean molting on demand
University of Alabama at Birmingham (UAB) researchers are close to unraveling intricate cellular pathways that control molting in blue crabs. The discoveries could revolutionize the soft-shell crab industry, generating new jobs and additional profits for the U.S. fishing industry along the coastal Southeast. view more (2009-10-28)
The cosmos is green: Researchers catch nature in the act of 'recycling' a star
For the first time, researchers have observed a singular cosmic act of rebirth: the transformation of an ordinary, slow-rotating pulsar into a superfast millisecond pulsar with an almost infinitely extended lifespan. view more (2009-05-22)
Researchers Turning Freshwater Farm Ponds into Crab Farms
Work by researchers at North Carolina State University is leading to a new kind of crab harvest - blue crabs grown and harvested from freshwater ponds, instead of from the sea. view more (2008-10-10)
Stellar forensics with striking new image from Chandra
A spectacular new image shows how complex a star's afterlife can be. By studying the details of this image made from a long observation by NASA's Chandra X-ray Observatory, astronomers can better understand how some stars die and disperse elements like oxygen into the next generation of stars and planets. view more (2007-10-24)
Old pulsars still have new tricks to teach us
The super-sensitivity of ESA's XMM-Newton X-ray observatory has shown that the prevailing theory of how stellar corpses, known as pulsars, generate their X-rays needs revising. view more (2006-07-26)
Crab claws pack strengthening bromide-rich biomaterial
Next time you have an unlucky encounter with a crab's pinchers, consider that the claw tips may be reinforced with bromine-rich biomaterial 1.5 times harder than acrylic glass and extremely fracture resistant, says a University of Oregon scientist. view more (2009-02-26)
NASA's Fermi Telescope Probes Dozens of Pulsars
With NASA's Fermi Gamma-ray Space Telescope, astronomers now are getting their best look at those whirling stellar cinders known as pulsars. view more (2009-07-07)
