How urchins see when they have no eyes

How urchins see when they have no eyes

Sea urchins don't have eyes, yet they react to light. How? Researchers from Sweden argue that the whole creature is studded with light sensors making it one giant seeing eye. So, while they have no eye as such, the urchins have many many light receptors, found on the end of the feet that cover their entire body.

Academics don't often call for less study, but experts on the Great Lakes in North America warn that unless radical action is taken quickly, Asian carp will cause terrible damage to native species and fishery economies. The study calls for action and even calling in the army in the shape of the U.S. Army Corps of Engineers to help separate the lakes from the carp's Mississippi home.

An innovative use of MRI scanners and tarantulas has revealed intriguing new information about a spider's heart - it may show a double-beat, similar to that felt by humans. The research, being presented at this week's annual conference of the Society for Experimental Biology, in Glasgow, also holds out the possibility of investigating useful properties in spider venom, and the evolution of the brain.

Just how many species of desert tortoises are there? For 150 years since the species' discovery, it was believed that the desert tortoise is one species. However, evidence has been mounting that desert tortoises should in fact be two separate species.

Right time for whales to return to New Zealand's calving grounds

Right time for whales to return to New Zealand's calving grounds

The playful antics of the gentle-but-gigantic right whales may be about to return to New Zealand, after an absence of 50 years - according to a new study published in Marine Ecology Progress Series. These formerly teeming calving grounds are being rediscovered by intrepid pioneers from near the Antarctic - and this may herald a return to the stunning yearly spectacle, last seen 100 years ago, before the whalers laid waste to these graceful giants.

The hidden world of the feathered color-spectrum has been mapped out in detail, in a new study of color - as seen from the bird's point of view - just published in Behavioral Ecology, out today. It seems for all their dazzle to our eyes, there is even more possibility for bird's evolutionary display to explore – as two-thirds of possible colors have yet to be painted on their plumage.

After a decade of surveying that has pooled marine experts from institutions from across the globe, the first results of TOPP - a critical part of the Census of Marine Life – are published in Nature today. They show that the Pacific Ocean's top predators move across an ever-changing oceanic landscape, in order to enjoy shifting biological feasts, that move with the the currents and the seasons.

Flowers need bees and birds and bees and many species of birds need flowers, but as global warming changes the flowering calendar of mountain plants, this symbiotic relationship could fail disastrously for both parties.

Captive chimps suffer from post-traumatic stress disorder (PTSD), depression, and other mental illnesses, researchers find. Laboratory testing, capture, isolation from social groups, and even captivity in "enriched" environments lead to abnormal behavior in chimps, two studies show.

A weird denizen of the Borneo forests, one that is orange and spongey, has been described in the latest issue of Mycologia. His name - why Spongiforma squarepantsii of course! And the tropical jungles of the world are sure to be home to many more oddities, as 95% of fungi remain undiscovered.

Researchers have discovered that Google Earth provides a novel and inexpensive way to monitor animal behaviour. The beauty of Google Earth for scientists is that animal behaviour which leaves a footprint on the landscape can be observed remotely.

Fascinating new work on the diving bell spiders - amazing arachnids that live under water in their own personal air bubbles - has shed light onto how they make use of 'bubble technology'. It seems, says the paper in the Journal of Experimental Biology, that the spiders can stay submerged for longer than thought - all the better to catch their prey.

WWF announced that scientists have found over 600 new species in Madagascar between 1999 and 2010. Species evolved on Madagascar that are found nowhere else. In addition, there is a high diversity of habitats found on the island, from coral reefs to spiny forests.

The great snipe doesn't exactly look the part, but these chubby Scandinavian natives fly over 4,000 miles in just two days making in the fastest long distance migration on record. Starting in Sweden, these incredible travellers put in a 60-mile-an-hour two day shift to arrive 4,200 miles away south of the Sahara in Africa.

Jellyfish swarms have been on the increase in many coastal waters, and that increase may be bad news for other predators, such as fish and shellfish. That's according to a paper in Proceedings of the National Academy of Sciences, which describes how the bacteria chowing down on jellyfish slime are knocking out important links in the food chain.

With its heart beating at 1,300-beats-per-minute, a male golden-collared manakin shoots through its rainforest home at extraordinary speed, all in search of a mate. For the females, who have larger visual processing areas in their brains than the males, it's a cold calculation of picking the strongest.
