(PhysOrg.com) -- Proteins are solids. When heated they do not melt; instead, they decompose or sublime directly to the gas phase at low pressures. They cannot be converted into a liquid form unless they are dissolved in a solvent. A team at the University of Bristol (UK) and the Max Planck Institute of Colloids and Interfaces in Golm (Germany) has now successfully liquefied a protein without the assistance of a solvent. As the research team headed by Stephen Mann reports in the journal Angewandte Chemie, the trick is to modify the surface of the protein with a polymeric surfactant. http://www.physorg.com/news169725144.html Chemistry Mon, 17 Aug 2009 10:53:08 EST news169725144 (PhysOrg.com) -- Excavations led by a University of Toronto archaeologist at the site of a recently discovered temple in southeastern Turkey have uncovered a cache of cuneiform tablets dating back to the Iron Age period between 1200 and 600 BCE. Found in the temple's cella, or 'holy of holies', the tablets are part of a possible archive that may provide insights into Assyrian imperial aspirations. http://www.physorg.com/news169121163.html Other Sciences Mon, 10 Aug 2009 11:06:48 EST news169121163 New research involving scientists from the National Oceanography Centre, Southampton (NOCS) highlights the potential utility of iron isotopes for addressing important questions in ocean science.

These same compounds may have been key to methane reduction in the early, oxygenless days of the planet's atmosphere. http://www.physorg.com/news166367681.html Space & Earth Thu, 09 Jul 2009 14:15:22 EST news166367681 Iron supplements do not increase the likelihood of contracting malaria and should not be withheld from children at risk of the disease, despite World Health Organisation (WHO) guidelines to the contrary, a new review by Cochrane Researchers suggests. http://www.physorg.com/news166252262.html Medicine & Health Wed, 08 Jul 2009 06:11:33 EST news166252262 Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic.

A study in Italy has investigated the link between ferritin and steatosis in a non-obese cohort of non-alcoholic patients. In southern European populations, high ferritin levels, after exclusion of diagnosis of HH, represent a risk factor for steatosis and clinical relevance, being associated with low platelet count. http://www.physorg.com/news161443860.html Medicine & Health Wed, 13 May 2009 14:31:40 EST news161443860 Iron chelating drugs have been heavily promoted for use in patients with primary myelofibrosis (PMF), a form of blood cancer often treated with blood transfusion. These drugs, however, which withhold available iron in the body, are highly expensive and potentially toxic. A new study published in American Journal of Hematology finds that their increased use has been propagated by non-evidence based, and often industry-sponsored, statements and opinions, rather than original research, and that the conclusions are often based on poor data. http://www.physorg.com/news161278224.html Medicine & Health Mon, 11 May 2009 16:30:39 EST news161278224 Oceanographers Jim Bishop and Todd Wood of the U.S. Department of Energy's Lawrence Berkeley National Laboratory have measured the fate of carbon particles originating in plankton blooms in the Southern Ocean, using data that deep-diving Carbon Explorer floats collected around the clock for well over a year. Their study reveals that most of the carbon from lush plankton blooms never reaches the deep ocean. http://www.physorg.com/news160833920.html Space & Earth Wed, 06 May 2009 13:05:59 EST news160833920 Iron plays a large role in brain development in the womb, and new University of Rochester Medical Center research shows an iron deficiency may delay the development of auditory nervous system in preemies.

Experiments indicate that the velocity of shear waves (s-waves) in Earth`s lower mantle between 660 and 2900 km depth is strongly dependent on the orientation of ferropericlase. In the latest issue of Science (Vol. 325, 10.04.2009), researchers from the German Research Center for Geosciences GFZ, the Karlsruhe Institute of Technology, the University of Bayreuth, and Arizona State University report unexpected properties of ferropericlase, which is presumably the second most abundant mineral of the lower mantle. http://www.physorg.com/news158840427.html Space & Earth Mon, 13 Apr 2009 11:21:05 EST news158840427 Two places on opposite sides of Earth may hold the secret to how the moon was born.
