(PhysOrg.com) -- Making comparisons between objects, like comparing a tiger to a cat, is elemental in the development of a child`s ability to grasp the concept of categories. http://www.physorg.com/news165589455.html Medicine & Health Tue, 30 Jun 2009 14:05:48 EST news165589455 Nonhormonal treatment regimens, including anthracycline-based regimens and taxanes, have improved overall survival in women with advanced (metastatic or recurrent inoperable) breast cancer over the last 35 years, according to a systematic review published December 9 in the Journal of the National Cancer Institute. http://www.physorg.com/news148067994.html Medicine & Health Tue, 09 Dec 2008 17:59:54 EST news148067994 Hitachi announced today that it released 'GazoPa book' a new Facebook application that enables users to search for images both inside Facebook and on the web similar to their profile photo and photos at their albums. http://www.physorg.com/news148056115.html Technology Tue, 09 Dec 2008 14:41:55 EST news148056115 Many studies of evolution focus on the benefits to the individual of competing successfully - those who survive produce the most offspring, in Darwin's classic 'survival of the fittest'. But how does this translate to the evolution of species? A new paper, published in this week's issue of PLoS Biology, studies an aspect of the natural world that, like survival of the fittest individual, is explained by natural selection: namely, mutualism - an interaction between species that has benefits for both. The work shows that some species of butterfly that live alongside one another have evolved in ways that, surprisingly, benefit both species. http://www.physorg.com/news147422979.html Biology Tue, 02 Dec 2008 06:49:39 EST news147422979 Newly reported data presented at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF) from the SYNTAX clinical trial (SYNergy Between PCI With TAXUS and Cardiac Surgery) reveal similar safety and efficacy outcomes when the use of a drug-eluting stent is compared to heart bypass surgery in patients with left main disease. http://www.physorg.com/news143270858.html Medicine & Health Wed, 15 Oct 2008 06:27:38 EST news143270858 (PhysOrg.com) -- The election year is in full swing, complete with allegations of class warfare and claims about which candidates cater to the rich and which candidates will best serve the interests of the poor and the middle class. But a new study, co-authored by North Carolina State University researcher Dr. Chris Ellis, explores the idea that Congress and the White House act on behalf of the wealthy - and shows that it would be impossible to cater solely to any socioeconomic group, because people's preferences tend to be overwhelmingly similar when it comes to how the federal government should spend its money. http://www.physorg.com/news142183151.html Other Sciences Thu, 02 Oct 2008 16:19:11 EST news142183151 Syntactic persistence is the tendency for speakers to produce sentences using similar grammatical patterns and rules of language as those they have used before. Although the way this occurs is not well understood, previous research has indicated that this effect may involve a specific aspect of memory function. Memory is made up of two components: declarative and procedural. Declarative memory is used in remembering events and facts. Procedural memory helps us to remember how to perform tasks, such as playing the piano or riding a bike. A recent study suggests that the common phrase, "it's so easy, it's like riding a bike" should perhaps be replaced with "it's so easy, it's like forming a sentence." http://www.physorg.com/news141396038.html Medicine & Health Tue, 23 Sep 2008 13:40:38 EST news141396038 Echolocation may have evolved more than once in bats, according to new research from the University of Bristol published this week in Proceedings of the National Academy of Sciences (PNAS). http://www.physorg.com/news139742996.html Biology Thu, 04 Sep 2008 10:29:56 EST news139742996
