Using atoms at temperatures colder than deep space, Rice University physicists have delivered overwhelming proof for a once-scoffed-at theory that's become a hotbed for research some 40 years after it first appeared. In a paper available online in Science Express, Rice's team offers experimental evidence for a universal quantum mechanism that allows trios of particles to appear and reappear at higher energy levels in an infinite progression. The triplets, often called trimers, form in special cases where pairs cannot. http://www.physorg.com/news179749630.html Physics Fri, 11 Dec 2009 10:27:59 EST news179749630 (PhysOrg.com) -- New research appears to have ended a scientific debate that has vexed palaeontologists for almost 100 years. http://www.physorg.com/news179660768.html Other Sciences Thu, 10 Dec 2009 09:58:10 EST news179660768 Ostrich eggshell (OES) beads from SDG site reflect primordial art and a kind of symbolic behavior of modern humans. Two different manufacturing pathways are usually used in the manufacture of OES beads in Upper Paleolithic. Pathway 1 is identified from these collections; blanks are drilled prior to being trimmed to rough discs. Based on stratigraphic data and OSL dating, these ostrich eggshell beads are probably in Early Holocene (10 ka BP). http://www.physorg.com/news179401911.html Other Sciences Mon, 07 Dec 2009 09:52:26 EST news179401911 The largest fish kill in Illinois history -- expected to net 100 tons of fish including, hopefully, some Asian carp -- is to start Wednesday south of Chicago in an attempt to make sure none of the feared carp make it past an electric barrier while it is shut down for maintenance. http://www.physorg.com/news178952297.html Biology Wed, 02 Dec 2009 04:58:48 EST news178952297 In today's world, legal issues and controversies are not only tried in the court of law, but also in the "court" of public opinion. However, corporate lawyers tend to separate legal activities from public relations strategies. In addition, they have often viewed media issues as separate from those involved in providing legal advice. http://www.physorg.com/news177692444.html Other Sciences Tue, 17 Nov 2009 18:30:01 EST news177692444 (PhysOrg.com) -- Scientists have gained new insight into the makeup of ancient meteorites called Carbonaceous Chondrites, in research published in the October edition of the journal Earth Science and Planetary Letters. http://www.physorg.com/news177264804.html Space & Earth Thu, 12 Nov 2009 16:14:14 EST news177264804 Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been routinely underestimating the age of many specimens by 200 to 600 percent. http://www.physorg.com/news177083943.html Biology Tue, 10 Nov 2009 13:59:42 EST news177083943 Fossil land snail shells found in ancient soils on the subtropical eastern Canary Islands show that the Spanish archipelago off the northwest coast of Africa has become progressively drier over the past 50,000 years. http://www.physorg.com/news175884639.html Space & Earth Tue, 27 Oct 2009 17:51:31 EST news175884639 Twice in the Earth's history, living creatures underwent astonishing growth spurts, and each time, new organisms emerged that were a million times larger than anything that had existed before. http://www.physorg.com/news175876056.html Space & Earth Tue, 27 Oct 2009 15:28:16 EST news175876056 While nepotism may have negative connotations in politics and the workplace, being surrounded by your relatives does lead to better group dynamics and more cooperation in some animals.

It may seem strange that such a founding father of modern biological thought as Darwin could run afoul of something so basic, but biologists over past decades, including such giants as Harvard`s Ernst Mayr, perceived Darwin`s understanding of species as somewhat fuzzy. http://www.physorg.com/news173634347.html Biology Thu, 01 Oct 2009 16:46:18 EST news173634347 The world's largest living lizard species, the Komodo dragon (Varanus komodoensis), is vulnerable to extinction and yet little is known about its natural history. New research by a team of palaeontologists and archaeologists from Australia, Malaysia and Indonesia, who studied fossil evidence from Australia, Timor, Flores, Java and India, shows that Komodo Dragons most likely evolved in Australia and dispersed westward to Indonesia. http://www.physorg.com/news173515666.html Other Sciences Wed, 30 Sep 2009 08:40:03 EST news173515666 A skull fragment thought to come from Adolf Hitler is in fact that of an unidentified woman, according to a US study that has resurrected questions about the Nazi leader's death. http://www.physorg.com/news173421782.html Other Sciences Tue, 29 Sep 2009 05:44:15 EST news173421782 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.
