The origin of different sexes
22 April, 2010Coming straight from the pond - a multicellular green alga may have unlocked the secrets behind the evolution of different sexes.
The scientific brain
07 April, 2010There is a striking similarity between how the human brain determines what is going on in the outside world and the job of scientists. Both process predictable sensory input in an efficient manner but require more effort when predictions are not fulfilled.
Bacteria-killing proteins cover blood-type blind spot
17 February, 2010A set of proteins found in our intestines can recognise and kill bacteria that have human blood-type molecules on their surfaces, scientists at Emory University School of Medicine have discovered.
Molecular causes of genetic diseases
15 February, 2010A new study using bioinformatics, led by scientists at the Buck Institute for Age Research, reports the ability to predict the molecular cause of many inherited genetic diseases. These predictions involve tens of thousands of genetic disease-causing mutations and have led to the creation of a web-based tool available to academic researchers who study disease.
What came first in the origin of life?
12 January, 2010A study carried out by three European researchers contradicts the 'metabolism first' hypothesis in the origin of life.
Monitoring protein-tissue interactions in real time
02 January, 2010Ridgeview Instruments AB’s LigandTracer Grey facilitates kinetic measurements on living cells by enabling researchers to follow protein-cell interactions in real time.
Diagnosis emerges from complete sequencing of patient's genes
21 October, 2009Scientists have used high-throughput DNA sequencing technology to diagnose a genetic disease by completely sequencing all of a patient’s genes.
How plants recognise their siblings
16 October, 2009With no visible sensory markers, plants are able to recognise plants grown from the same mother. Plants exhibit less competitive behaviour towards their siblings than they do towards strangers.
Insect growth chamber
10 September, 2009Caron's newly designed 25 cu ft Insect Growth Chamber, Model 6025-3, is said to provide a solution for a wide variety of entomological studies.
Y chromosome may not be a dysfunctional loner after all
09 September, 2009X and Y chromosomes have been shown to exchange DNA, refuting the scientific theory that the two chromosomes do not communicate at all.
Biomedical engineering teaching equipment
10 August, 2009 byEmona Instruments has been appointed as the Australian distributor for the CleveLabs range of biomedical engineering teaching systems.
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.
