Marriage and life expectancy

(Max-Planck-Gesellschaft) Marriage is more beneficial for men than for women - at least for those who want a long life. Previous studies have shown that men with younger wives live longer. While it had long been assumed that women with younger husbands also live longer, in a new...

Long-term studies of chronic disease needed in Africa

(Public Library of Science) There is an urgent need for longitudinal cohorts based in sub-Saharan Africa to address the growing burden of non-communicable diseases in the region, according to a new article published in PLoS Medicine.

Automated Forensic DNA Methods: Relieving the Pain of Validation

Apr 21

Automation can increase a forensics lab's sample processing capacity, but it can also add to the complexity of system verification and validation.

Successful Sample Identification

Apr 1

2D Barcodes ensure that a multitude of samples can be tracked in a variety of storage conditions.

Multi-Parametric Cellular Analysis

Mar 23

Flow cytometers perform a variety of multi parametric applications and have been used for an expanding set of cell analysis applications over the past forty years.

Maintaining a Healthy Cell Culture Environment

Mar 23

Investing in best practices and products at the beginning of any experiment is the most time- and cost-effective way to approach cell culture.

Step up to the MIQE

Mar 30

Over the years, polymerase chain reaction (PCR) has evolved into a readily automated, high throughput quantitative technology. Real-time quantitative PCR (qPCR) has become the industry standard for the detection and quantification of nucleic acids for multiple application, including quantification of RNA levels. But a lack of consensus among researchers on how to best perform and interpret qPCR experiments presents a major hurdle for advancement of the technology. This problem is exacerbated by insufficient experimental detail in published work, which impedes the ability of others to accurately evaluate or replicate reported results.

Fast Optimization of a Multiplex Influenza Identification Panel Using a Thermal Gradient

Mar 30

The year 2009 was marked by the emergence of a novel influenza A (H1N1) virus that infects humans. There is a need to identify the different strains of influenza virus for purposes of monitoring the H1N1 strain pandemic and for other epidemiological and scientific purposes.

Advantages of Monolithic Laser Combiner Technology in Confocal Microscopy Systems

Jan 6

Fluorescence microscopy techniques require a reliable light source at the desired wavelength or wavelengths, with minimal downtime for maintenance and alignment. Lasers are a popular light source, although the alignment and upkeep of laser combiners is a time-consuming prospect for many users.

Size-Exclusion Chromatography for Purification of Biomolecules

Dec 2 2009

Size-exclusion chromatography (SEC) is a popular method to separate biomolecules based on their size. Primarily, it is applied to the separation of biopolymers such as proteins and nucleic acids, i.e. water-soluble polymers.

Using the Tecan Genesis Workstation to Automate a Cytometric Bead Array (CBA) Immunoassay

Mar 11

The poster describe the process involved in automating a Cytometric Bead Array (CBA) immunoassay developed to measure relative concentrations of serum antibodies against Tetanus (TT), Sperm Whale Myoglobin (SWM) and Keyhole Limpet Hemocyanin (KLH) in KLH-immunized volunteers.

Ensuring Quality in Assays Performed with Automated Liquid Handlers

Feb 2

The focus of this presentation is to highlight the need of ensuring quality in important assays performed with automated liquid handlers. Nearly all assays performed within a laboratory are volume-dependent. In turn, all concentrations of biological and chemical components in these assays, as well as the associated dilution protocols, are volume-dependent. Because analyte concentration is volume-dependent, an assay’s results might be falsely interpreted if liquid handler variability and inaccuracies are unknown or if the system(s) go unchecked for a long period.

Inkjet System for Protein Crystallography

Feb 1

X-ray crystallography is used routinely by scientists to obtain the three dimensional structure of a biological molecule of interest.Such information can be used to determine how a pharmaceutical interacts with a protein target and what changes might improve functionality. However, the crystallization of macromolecules still remains a serious hindrance in structural determination despite impressive advances in screening methods and technologies.

Attention Deficit & Hyperactivity in a Drosophila Memory Mutant

Attention Deficit & Hyperactivity in a Drosophila Memory Mutant

Nov 9 2009

Action selection is modulated by external stimuli either directly or via memory retrieval. In a constantly changing environment, animals have evolved attention-like processes to effectively filter the incoming sensory stream. These attention-like processes, in turn, are modulated by memory. The neurobiological nature of how attention, action selection and memory are inter-connected is unknown. We describe here new phenotypes of the memory mutant radish in the fruit fly Drosophila.
