How Science and Technology Influence Language
Dec 24 2010
Have you ever been Plutoed (demoted)? Is your inbox clogged with "bacn" (spam by personal request)? Are you a lifehacker (master at optimizing everyday routines)? Jonathon Keats, artist and author of Virtual Words, explains how science and technology influence language, and vice versa.
Lunar Eclipse Is A Winter Sky Highlight
Dec 17 2010
The shadow of the Earth will pass over the moon late Monday, Dec. 20, into Tuesday morning. Meteorologist and sky watcher Joe Rao discusses the lunar eclipse, and other astronomical events to look out for this winter, including an early dawn visit by Venus on Christmas Day.
Living Without Fear
Doctors at University of Iowa have been studying a female patient they call "SM" for more than 20 years. SM has a damaged amygdala, a part of the brain. As a result, she doesn't experience fear. Daniel Tranel explains what doctors have learned about fear from SM, and how that information...
Visions Of Energy Efficiency Danced In Their Heads
Homeowners hoping to save on utility bills may want to ask Santa for a storm door or insulation. Dec. 31 is the deadline for the energy tax credits that could cut your tax bill by up to $1,500. Science Friday runs down how to save some green this winter.
Science Diction: The Origin Of The Word 'Comet'
Although comets were sighted at least as early as 1000 B.C., Greek natural philosophers named them sometime around 500 B.C., using the Greek word kometes for "a head with long hair." Science historian Howard Markel discusses the word's origins and the study of comets through the centuries.

Saving Cells: Image Processing for Improved Viability, Part II: Iterative Deconvolution
3D light microscopy and deconvolution provide a means to investigate 3D structure, providing near-confocal quality images without the temporal requirements or potentially damaging phototoxicity associated with other 3D imaging technologies. This article is Part II in a series regarding viability, resolution improvement, and measurement in fluorescence imaging. Part I focused on spectral unmixing.

Production of Recombinant Proteins and Monoclonal Antibodies in Hollow Fiber Bioreactors
Jan 25
While well-understood, robust and convenient, classical batch-style 2-D culture on non-porous supports or 3-D suspension culture in other devices are really not very biologically relevant models. Cell culture conditions can affect the quality of the antibody or protein produced.
Selecting Robots for Use in Drug Discovery and Testing
Dec 6 2010
Drug discovery and testing, with their need for speed, repeatability and verification, are ideally suited to benefit from robot automation. It is therefore not surprising that robots have been at the forefront of automation developments in both these areas.
HP Scalable Network Storage Systems for Life Sciences
Sep 13 2010
Life sciences research today is advancing exponentially, each step bringing us closer to the realization of truly personalized medicine–preventive care and treatments designed specifically for each individual. In the near future, PCPGM healthcare researchers expect to be able to use predictive genetic testing to create custom treatment plans for individuals and deliver dramatic improvements over today’s one-size-fits-all approach. But research capabilities are only part of the equation; current storage and operating capacities must also evolve to accommodate ever-expanding amounts of data before the goal of personalized medicine can be realized.
Step up to the MIQE
Mar 30 2010
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.
Using the Tecan Genesis Workstation to Automate a Cytometric Bead Array (CBA) Immunoassay
Mar 11 2010
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 2010
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 2010
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
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.
