(PhysOrg.com) -- A new investigation of a fossilized tracksite in southern Africa shows how early dinosaurs made on-the-fly adjustments to their movements to cope with slippery and sloping terrain. Differences in how early dinosaurs made these adjustments provide insight into the later evolution of the group. http://www.physorg.com/news174057636.html Other Sciences Tue, 06 Oct 2009 17:50:02 EST news174057636 Very low birth-weight newborns who received the milk protein lactoferrin alone or in combination with a probiotic had a reduced incidence of late-onset sepsis, according to a study in the October 7 issue of JAMA. http://www.physorg.com/news174065557.html Medicine & Health Tue, 06 Oct 2009 16:50:28 EST news174065557 (PhysOrg.com) -- An 85 million-year-old plesiosaur fossil has been found with over 80 shark's teeth, suggesting the animal was the victim of sharks in a feeding frenzy.

In an article in Ecology Letters, Wageningen (The Netherlands) ecologists Frank Berendse and Marten Scheffer postulate that flowering plants changed the conditions during the Cretaceous period to suit themselves. The researchers have consequently provided an entirely new explanation for what Charles Darwin considered to be one of the greatest mysteries with which he was confronted. http://www.physorg.com/news166805247.html Biology Tue, 14 Jul 2009 15:49:18 EST news166805247 On the heels of his discovery in Montana of the first trace fossil of a dinosaur burrow, Emory University paleontologist Anthony Martin has found evidence of more dinosaur burrows - this time on the other side of the world, in Victoria, Australia. The find, to be published this month in Cretaceous Research, suggests that burrowing behaviors were shared by dinosaurs of different species, in different hemispheres, and spanned millions of years during the Cretaceous Period, when some dinosaurs lived in polar environments. http://www.physorg.com/news166471265.html Other Sciences Fri, 10 Jul 2009 19:20:01 EST news166471265 Earth's 4.5-billion-year history is filled with several turning points when temperatures changed dramatically, asteroids bombarded the planet and life forms came and disappeared. But one of the biggest moments in Earth's lifetime is the Cambrian explosion of life, roughly 540 million years ago, when complex, multi-cellular life burst out all over the planet. http://www.physorg.com/news166288435.html Space & Earth Wed, 08 Jul 2009 16:14:18 EST news166288435 Viruses can cost winegrowers an entire harvest.
