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)
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)
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...

MU Scientist Discovers 'Firework' Display in Helix Nebula
A star does not die without getting noticed and may even leave the universe with "fireworks." At the end of its life cycle, a star begins to collapse in the middle and throws new material into space. view more (2009-07-21)
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)
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)
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)
Astronomers catch binary star explosion inside nebula
The explosion of a binary star inside a planetary nebula has been captured by a team led by UCL (University College London) researchers - an event that has not been witnessed for more than 100 years. view more (2008-11-20)
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)
Hubble's 17th anniversary -- extreme star birth in the Carina Nebula
Hubble's new view of the Carina Nebula shows the process of star birth at a new level of detail. view more (2007-04-25)
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)

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)
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)
The colourful demise of a Sun-like star
A brand new image taken with Hubble's Wide Field Planetary Camera 2 shows the planetary nebula NGC 2440 - the chaotic structure of the demise of a star. view more (2007-02-15)
Hydrocarbons in the Horsehead mane
Observing the edge of the famous Horsehead Nebula with the IRAM interferometer located on the Plateau de Bures (France), a team of French and Spanish astronomers discovered a large quantity of small hydrocarbon molecules. This is a surprise because the intense UV radiation illuminating the Nebula should destroy the small hydrocarbons near the... view more... (2005-02-21)
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)
