(PhysOrg.com) -- A new study may have solved the long-standing question of how elephants sleep during their long migrations at sea, when they can be away from land for up to eight months. http://www.physorg.com/news177315628.html Biology Fri, 13 Nov 2009 06:22:02 EST news177315628 When the ancestors of living cetaceans -whales, dolphins and porpoises -first dipped their toes into water, a series of evolutionary changes were sparked that ultimately nestled these swimming mammals into the larger hoofed animal group. But what happened first, a change from a plant-based diet to a carnivorous diet, or the loss of their ability to walk? http://www.physorg.com/news173031353.html Biology Thu, 24 Sep 2009 18:00:04 EST news173031353 A 1,000-pound slab of sandstone lifted off a beach in Santa Cruz County, Calif., Wednesday may provide a better glimpse of what plied the seas 5 million years ago. http://www.physorg.com/news169404317.html Other Sciences Thu, 13 Aug 2009 17:45:47 EST news169404317 (AP) -- The only tweets during the Miami Dolphins scrimmage Saturday will come from the officials' whistles. http://www.physorg.com/news168765200.html Technology Thu, 06 Aug 2009 08:40:01 EST news168765200 Two researchers from the Polytechnic University of Catalonia (UPC) and the University of Aberdeen in the United Kingdom have shown for the first time that the law of brevity in human language, according to which the most frequently-used words tend to be the shortest, also extends to other animal species. The scientists have shown that dolphins are more likely to make simpler movements at the water surface. http://www.physorg.com/news168156268.html Biology Thu, 30 Jul 2009 07:20:03 EST news168156268 (PhysOrg.com) -- The seemingly effortless way dolphins and porpoises slice through the water and the unique capabilities of the supersonic Concorde airplane have more in common than one might think. http://www.physorg.com/news165592631.html Biology Tue, 30 Jun 2009 14:57:44 EST news165592631 Same-sex behavior is a nearly universal phenomenon in the animal kingdom, common across species, from worms to frogs to birds, concludes a new review of existing research. http://www.physorg.com/news164376975.html Biology Tue, 16 Jun 2009 13:46:24 EST news164376975 (PhysOrg.com) -- More whales, dolphins and porpoises than was previously thought could be at risk from the effects of climate change, according to a new study. http://www.physorg.com/news163082415.html Biology Mon, 01 Jun 2009 13:41:04 EST news163082415 A porpoise at Harderwijk dolphin centre in the Netherlands has become only the second to give birth in captivity, the centre announced, but the happy event leaves an enigma: is it a boy or a girl? http://www.physorg.com/news160989639.html Biology Fri, 08 May 2009 08:21:07 EST news160989639 Dolphins have a clever trick for overcoming sleep deprivation. Sam Ridgway from the US Navy Marine Mammal Program explains that they are able to send half of their brains to sleep while the other half remains conscious. What is more, the mammals seem to be able to remain continually vigilant for sounds for days on end. http://www.physorg.com/news160384772.html Biology Fri, 01 May 2009 08:19:57 EST news160384772 They say dolphins are smart, and now people are borrowing a technology that was first used on the mammals. http://www.physorg.com/news157979058.html Medicine & Health Fri, 03 Apr 2009 12:05:02 EST news157979058 (PhysOrg.com) -- There was something peculiar about dolphins that stumped prolific British zoologist Sir James Gray in 1936. He had observed the sea mammals swimming at a swift rate of more than 20 miles per hour, but his studies had concluded that the muscles of dolphins simply weren't strong enough to support those kinds of speeds. The conundrum came to be known as "Gray's Paradox." http://www.physorg.com/news146730722.html Physics Mon, 24 Nov 2008 06:32:02 EST news146730722 (PhysOrg.com) -- Marine mammal experts have uncovered a new species of dolphin in Australian waters, challenging existing knowledge about bottlenose dolphin classifications and highlighting the country's marine biodiversity. http://www.physorg.com/news146494868.html Biology Fri, 21 Nov 2008 13:01:08 EST news146494868 Spinner dolphins have long been known for their teamwork in capturing prey but a new study using high-tech acoustics has found that their synchronization is even more complex than scientists realized and likely evolved as a strategy to maximize their energy intake. http://www.physorg.com/news143803233.html Biology Tue, 21 Oct 2008 10:20:33 EST news143803233
