Differences between induced pluripotent and embryonic stem cells
03 July, 2009Embryonic stem cells and induced pluripotent stem cells have been found to have inherent molecular differences, making it possible to clearly distinguish between the two cell types.
Flow cytometric chromosome classification
15 May, 2009 by Beckman CoulterFlow cytometric chromosome classification has been routinely used in the analysis of mammalian karyotypes as well as to assess chromosomal abnormalities. Download this tech paper for more information on how highly purified fractions of chromosomes can be isolated rapidly from the labelled chromosomes using a cell sorter.
A virologist's perspective on Influenza A (H1N1)
05 May, 2009Soon after scientists first isolated influenza A type viruses from pigs in 1931 and humans in 1933, they watched it break evolutionary barriers with alarming ease — infecting not only humans, but also aquatic birds, poultry, pigs, horses, dogs and other species. Now, with an intensifying outbreak driven by the emergence of a new strain of influenza A(H1N1), scientists once again have a unique opportunity to study viral evolution in action.
Sterile scalpels
07 April, 2009 byThe safety cover on the Feather Safety Razor Sterile Safeshield Scalpel protects the blade in procedure and handling. The clear protective shield can be advanced (to cover the blade) and retracted as required.
Mouse ventilator
07 April, 2009 byMice can be ventilated while myocardial infarctions are induced with the HSE-HA MiniVent.
Junk DNA and evolution
06 April, 2009Murdoch scientists have hypothesised that DNA junk is essential for evolution.
Lab-on-a-chip identifies how cancer cells detach
20 March, 2009Johns Hopkins engineers have invented a lab-on-a-chip that could be used to help discern how cancer cells detach from neighbouring tissue and spread throughout the body.
A machine to accurately control chromosomal separation
12 March, 2009University of Washington researchers are helping to understand a nanoscale machine that can separate chromosomes before cell division and could provide insight into chromosomal diseases, like Down Syndrome.
Creating controlled 3D microtissues
11 March, 2009Scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory can control how cells connect and assemble into three-dimensional, multicellular microtissues.
First draft of Neandertal genome unveiled
19 February, 2009A rough draft of the Neandertal genome has been completed by scientisis at the Max Planck Institute for Evolutionary Anthropology.
Challenging the infidelity 'myth'
12 February, 2009An examination of the Y chromosome of more than 1600 unrelated men with 40 different surnames has lead researchers to question the 'one-in-ten children are the result of infidelity' urban myth.
New class of non-protein coding genes
04 February, 2009Researchers have uncovered a vast new class of previously unrecognised mammalian genes that do not encode proteins, but instead function as long RNA molecules, and seem to play critical roles in both health and disease, including cancer, immune signalling and stem cell biology.
Dangerous DNA can cause cell suicide
16 January, 2009The discovery that some cells sacrifice themselves if they are infected with a virus will help improve understanding of how cells normally combat viral infection, and may also be relevant for the disease lupus, where the immune system attacks normal cellular proteins.
Fluorescent probes detect reactive oxygen species
16 December, 2008Reactive oxygen species can be detected and measured in vivo using a new family of fluorescent probes called Hydrocyanines.
Inducing chirality
03 December, 2008Chirality can be introduced by irradiation of molecules while adsorbed on a magnetised substrate.
