  1. When animals first crawled onto land, one of the greatest obstacles they had to contend with was figuring out how to breathe. No longer bathed in oxygen-rich marine waters, their gills would surely have dried out. Scientists have analyzed fossils from 500-million-year-old rocks that show one way these early pioneers may have dealt with this problem--the first terrestrial animals carried a shell on their backs.

  2. The International Polar Year concluded in March 2009 with a tangible legacy in the form of a network of databases on marine biodiversity that will serve as clearinghouse for all biodiversity-related data gathered since the very first Antarctic research expeditions. The network gathers data describing the species themselves as well as information about their collection history, allowing scientists and conservationists to access the first rigorous census of Antarctic marine life.

  3. 31.5C is very scary.... You really ought to try using a fan at least to increase evaporation if you can't afford a chiller.
  4. Really? which thread? i havent seen any spam yet for a very very long time yet?
  5. How marine microbe Trichodesmium fixes nitrogen and carbon dioxide apparently at the same time has long puzzled scientists. Using NanoSIMS imaging technology, this study supports the theory that the cyanobacteria separates the processes by time, among other findings. View the full article
  6. not scaring him. just pointing out some facts. I have seen too many 'dropouts' who can't go all the way....
  7. nice tank! Watch your bubble and octo... nighttime could be warfare time with stingers from both.. your GSP could be hit.
  8. Higher temps increases the toxicity of waste materials. Also brings reduced oxygen levels. It also makes the metabolic rates of livestock increase. All bad. It's possible but not recommended. It's a fine balance but a slight tilt could crash the system if lets say your pumps overheats or your MHs stay on for a long time.
  9. Seahorses are a lot more demanding than you think. They eat non-stop and need the right kind of foods... ie. live shrimps. Unless they are trained or YOU train them yourself intensively until they do. Water quality has to be good too.
  10. Want an opinion? It's an expensive hobby. No denying it. Dun go down the slippery slope unless you have deep pockets. Either you end up killing your livestock or yourself for 'wasting' money. These are extraordinary times and priorities have to be made. Save up your money for better things and use that to improve your studies/work/business opportunities. When you are richer and the world isn't dead yet... i am sure you can enter the hobby with passion and stability.
  11. please try to be more descriptive with your topic. It's very annoying not just for me but everyone else. You want help quick... this is something to consider. thanks!
  12. Ya, the mod is too busy to entertain. But i am keeping eye on the atmosphere here... sh*t-stirrers will have their accounts suspended. I do not intervene in personal differences or disputes.... it is really not my responsibility. There is always the smalls claims court or the high court. Why can't everyone be open and honest to one another during deals? sigh.... "People are people so why should it be.. you and I should get along so awfully.. "
  13. A new, environmentally friendly coating that protects metals against corrosion in seawater has been developed by a team of researchers from England. They recently described how they had encapsulated spores from a bacterium into a sol-gel coating which then protected an aluminium alloy from microbial corrosion. View the full article
  14. Omega 3 fatty acids in fish oils can improve meat quality and reducing methane emissions in cows. Methane given off by farm animals is a major contribution to greenhouse gas levels. Researchers report that by including 2 percent fish oil in the diet of cattle they achieved a reduction in the amount of methane released by the animals. View the full article
  15. New research has shown that crabs not only suffer pain but that they retain a memory of it. The study looked at the reactions of hermit crabs to small electric shocks. View the full article
  16. Ants and bees have long been recognized as tireless workers, but now new research suggests they behave like model citizens too. Unlike herds of bison or shoals of fish -- where individuals may appear to be team players but actually behave according to their own interests -- some animals, including ants and bees, really do have the best interests of the group at heart.

  17. The impact fish stocking has on aquatic insects in mountain lakes can be rapidly reversed by removing non-native trout, according to a new study. View the full article
  18. For the first time, engineers have observed the initiation of a mass gathering and subsequent migration of hundreds of millions of animals -- in this case, fish. View the full article
  19. Large size and a fast bite spelled doom for bony fishes during the last mass extinction 65 million years ago (the same one that led to the extinction of thousands of species of flora and fauna, including dinosaurs). Today, those same features characterize large predatory bony fishes, such as tuna and billfishes, that are currently in decline and at risk of extinction themselves. The hardest hit species are consistently big predators. View the full article
  20. Seemingly dead cells perform a surprising task in the lens of a fish eye. Every morning and evening they change the lens?s capacity to refract light in order to enhance color perception during the day and night vision when it?s dark. View the full article
  21. Children of baby boomers aren't the only ones who have taken to setting up home far from where their parents live. A new study documents how larval dispersal connects marine fish populations in a network of marine protected areas -- information that is critical for fisheries managers. View the full article
  22. Biologists have discovered that the shell lengths of snails in the northwest Atlantic Ocean -- an important member of the Atlantic food chain -- have increased by 22.6 percent over the past century. View the full article
  23. The origin of the neurotoxin azaspiracid has finally been identified after a search for more than a decade. The azaspiracid toxin group can cause severe poisoning in human consumers of mussels after being enriched in the shellfish tissues. Scientists now report that a tiny algal species, the dinoflagellate Azadinium spinosum, is responsible. View the full article
  24. The fish species Astyanax fasciatus cannot see, but their unique technique for sensing their environment and the movement of water around them with gel-covered hairs that extend from their bodies may inspire a new generation of sensors that perform better than current active sonar.

  25. Among zebrafish, the eyes have it. Inside them is a mosaic of light-sensitive cells whose structure and functions are nearly identical to those of humans. There, biologists discovered a gene mutation that determines if the cells develop as rods (the photoreceptors responsible for dim-light vision) or as cones (the photoreceptors needed for color vision).
