  • Biology
  • The researchers report in the October 15 issue of the Journal of Experimental Biology that puffs of exhaled carbon dioxide first attract these mosquitoes, which then proceed to follow a broad skin odor plume, eventually landing on a human host. (redorbit.com)
  • In fact, such seeming incongruities make sense but only when we investigate the origins of the body's vulnerabilities while keeping in mind the wise words of distinguished geneticist Theodosius Dobzhansky: 'Nothing in biology makes sense except in the light of evolution. (sbu.edu)
  • sodium
  • Sodium has recently emerged as a prime candidate because it is less expensive, more abundant, and has similar chemical properties. (eurekalert.org)
  • To further support that this irreversibility was mainly due to the initial insertion and removal of sodium ions, the scientists tracked and mapped the corresponding chemical changes in real time. (eurekalert.org)
  • To the best of our knowledge the chemical, physical and toxicological properties of sodium aluminum fluoride have not been thoroughly investigated and reported. (espimetals.com)
  • Sodium rapidly forms caustic and highly corrosive sodium hydroxide with evolution of heat. (espimetals.com)
  • In the Chemical Gardens experiment, selected metal salts are added to an aqueous solution of sodium silicate (Na 2 SiO 3 ), resulting in the formation of inorganic structures that resemble plant growth in a time span ranging from minutes to hours. (nasa.gov)
  • lithium
  • Studying the light from two background stars that had passed through the system, the researchers noted the presence of lithium, a light element that can't exist in the interiors of stars, where nuclear fusion occurs. (eurekalert.org)
  • create
  • In the first paper we showed that you can create tension between a chemical and physical system to give rise to more complex systems. (blogspot.com)
  • If researchers can figure out a way to safely harness these, it may be possible to add genes that would create proteins to train the immune system against not just one, but multiple other viruses ( abstract ). (slashdot.org)
  • An international team of researchers led by the University of Leicester has "harnessed the power of evolution" to create a new drug for possible use against heart disease, inflammation and other illnesses. (redorbit.com)
  • gardens
  • Today the crew removed one Chemical Gardens 2 ampoule kit from a Cargo Transfer Bag, broke the seal between the two ampoules in each sample bag and mixed the contents of both. (nasa.gov)
  • Conducting this experiment in the microgravity environment onboard the ISS removes the gravity effects, ensures diffusion-controlled growth, and allows researchers a better assessment of initiation and evolution of chemical gardens. (nasa.gov)
  • The crew removed a Chemical Gardens ampoule kit from a Cargo Transfer Bag, break the seal between the ampoules and mix the contents of both. (nasa.gov)
  • pollution
  • In a day and age where chemical and radiation exposures from industrial pollution are ubiquitous and virtually unavoidable, it behooves us all to find ways to minimize exposure to them as well as to reduce their complex toxicities. (collective-evolution.com)
  • professor
  • Among other things, he claimed that the mystery of the naturalistic origin of life would be solved quite soon (I forget exactly when), and my then organic chemistry professor, a theistic chemical evolutionist and world expert on carbohydrate chemistry, repeated this in an origin of life lecture. (creation.com)
  • highly
  • Even though this was an unprecedented finding in itself, it posed a new question that came wholly unexpectedly: Nuclear pores are found in every cell in the world that has a nucleus, so it was labeled as "highly conserved," meaning it was always assumed that it was so important to the survival of an organism that evolution would never tamper with it. (innovations-report.com)
  • time
  • Darwin's theory of evolution by natural selection is well-established - organisms adapt over time in response to environmental changes. (blogspot.com)
  • presence
  • There's a lot of hedging in the replies to these questions, especially when it comes to regulations relating to the presence of such chemicals in the home, not just the workplace. (scientificamerican.com)
  • watch
  • We think this is really important," Kaplan said, "because now we can take this purified Treslin and the helicase, put them in a tube and watch the chemical modification occur. (eurekalert.org)
  • Cell
  • Treslin not only stimulates the chemical modification of the helicase, thereby activating it, but also assembles the helicase in preparation for cell division. (eurekalert.org)
