A long-held assumption confirmed Researchers at the SIB Swiss Institute of Bioinformatics and the EMBL-European Bioinformatics Institute have confirmed the long-held belief that studying the genes we share with other animals is useful. The study, published today in the open access journal PLoS Computational Biology, shows how bioinformatics makes it possible to test the fundamental principles on which life science is built. Studying genes helps life science researchers understand how...

Evidence that comparing genes across species is biologically useful Researchers at the SIB Swiss Institute of Bioinformatics and the EMBL-European Bioinformatics Institute have confirmed the long-held conjecture that studying the genes we share with other animals is a viable means of extrapolating information about human biology. The study, published in the open access journal PLoS Computational Biology, shows how bioinformatics makes it possible to test the conjecture. Scientists have...

DNA was originally thought to have a single function:  to help cells make the proteins they need.  Any DNA that is not immediately required to produce proteins was written off as "junk" and deemed unworthy of study.  Recently, however, it has become clear that junk DNA performs a wide range of important tasks.  As a result, attention is shifting to asking why some organisms have so much of it and other organisms so little.  A particular puzzle is posed by so-called...

Meiosis "“ the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell "“ is a major crossroads in all organisms reproducing sexually. Yet, how the cell precisely choreographs these chromosomal interactions is a long-standing question. New findings by University of California, Berkeley, scientists show that the cell's cytoskeleton, which moves things around in the cell, plays a critical role, essentially reaching into the nucleus to...

Research led by scientists at Iowa State University's Plant Sciences Institute has resulted in a process that will make genetic changes in plant genes much more efficient, practical and safe. The breakthrough was developed by David Wright, an associate scientist, and Jeffery Townsend, an assistant scientist, and allows targeted genetic manipulations in plant DNA, which could have a huge impact on plant genetic work in the future. Until now, when scientists introduced DNA into plants, they...

Since the sequencing of the human genome eight years ago, enormous progress has been made in analyzing and understanding it. Nevertheless, the function of most human genes is still barely understood. An important first step in determining the function of a gene or protein is to compare its sequence with the sequences of hundreds of other organisms that are experimentally easier to investigate. From the functions of related genes or proteins identified in these database searches, the...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
