Cost of LIMS: True Pricing includes more than Purchase, Implementation and Annual Licensing

May 18, 2015 3:02 pm | by Siri H. Segalstad | Comments

The real benefit of laboratory information management systems (LIMS) is difficult to calculate. Let’s take a look at some key considerations, starting with the question of whether to build the LIMS yourself or buy a commercial LIMS… Advocates for building a new LIMS themselves usually state that their lab is so unique, they cannot use a commercial LIMS. However, very few labs are truly unique ...

Computerized Systems in the Modern Laboratory: A Practical Guide

May 13, 2015 8:29 am | by John R. Joyce, Ph.D. | Comments

Scientific Computing periodically features special informatics focus articles that attempt to help you with such complex tasks as selecting a laboratory information management system or interfacing systems together. Unfortunately, there is only a limited amount of information that one can cram into one of these articles. Where we are limited to just a few pages for each of our attempts, Joe Liscouski has written a whole book on the subject

Scientists at Work: Most Days in the Life of an Astronomer aren’t spent at Telescopes

May 11, 2015 10:38 am | by Nicole Estefania Cabrera Salazar, Georgia State University | Comments

On a telescope at the summit of Mauna Kea in Hawaii, it’s not easy to put in a full night of work. At 14,000 feet, you’re operating at only 60 percent of the oxygen available at sea level, which makes concentrating difficult. Top that off with a shift that begins at 6:30 pm and ends at 6:30 am, and it becomes hard to imagine astronomers working like that year-round. Luckily, most of us don’t have to.

Designing and Managing the LIMS at Barcelona Biomedical Research Park's Animal Facility

May 7, 2015 8:18 am | by Helen Kelly | Comments

Today's LIMS allow research institutions to monitor and manage a broad array of biomedical research processes end-to-end and remotely. But how do they accommodate the ongoing flood of discoveries in areas such as genetics, the -omics, regenerative medicine and behavior, ongoing adjustments to workflows and protocols, tens of thousands of animals, and the evolution of legislative, welfare quality, and ethics directives?


Grow Your Own LIMS Code

May 5, 2015 9:05 am | by Helen Kelly | Comments

These days, using a LIMS seems to feature in every scientist's life, and for some small and medium-size labs, open source code is the way forward with a LIMS. In fact, businesses have grown up around helping labs implement open source LIMS and learn to make modifications in house. A bridge too far for a nonprofessional? Not according to Greg Wilson, who believes that most scientists can easily learn enough to slip into coding...

A Quantum Leap in Computing, Maybe

April 20, 2015 12:07 pm | by Thomas Sterling, Indiana University | Comments

Quantum Computing has been a concept since the 1980s that has remained outside the domain of real-world HPC. Through the era of Moore’s Law and exponential progress in feature size, clock rates and resulting performance, the need for alternative paradigms and technologies has attracted little interest. But there has remained a curiosity among a limited community that has driven slow but persistent advances in associated ideas.

The Case for User-Friendly Informatics in the Pharmaceutical QA/QC Lab

April 20, 2015 9:32 am | by Trish Meek, Thermo Fisher Scientific | Comments

All the computing power in the world isn’t useful if the software designed to access it is poorly designed. And we’re all much more discerning about user interfaces and usability: we expect our laboratory software to behave as intuitively as our smartphones. After all, laboratory employees are unlikely to be preoccupied with lines of codes and processors — they’re focused more on how easy the software is to use.

Opening Up Performance with OpenSpeedShop an Open Source Profiler

April 17, 2015 12:12 pm | by Rob Farber | Comments

There are a number of excellent commercial performance analysis tools on the market. Their big drawback is that they cost money. As a result, acquisition of commercial performance analysis software falls through the cracks, as most funding agencies discourage or prohibit the use of grant money for infrastructure improvements, and few grant authors are willing to take money away from research. Open-source tools are able to fill this gap.

The book assumes no formal statistical training on the part of the reader so the language is everyday plain. It seeks to clarify basic concepts and NOT teach the intricacies of the mathematics. Still, the book has much to recommend it.

Statistics Done Wrong: The Woefully Complete Guide

April 8, 2015 3:05 pm | by John A. Wass, Ph.D. | Comments

This delightful and informative guide from my friends at No Starch Press comes with the following cover blurb: “Statistics Done Wrong is a pithy, essential guide to statistical blunders in modern Science that will show you how to keep your research blunder-free.” It is somewhat pithy, but as to blunder free, I will quote the old maxim that “nothing is foolproof, as fools are so very clever.” Still, the book has much to recommend it.

Electromagnetic radiation – it might sound like something that you’d be better off avoiding, but electromagnetic waves of various kinds underpin our senses and how we interact with the world – from the light emissions through which your eyes perceive these words, to the microwaves that carry the Wi-Fi signal to your laptop or phone on which you’re reading it.

The World Health Organization reports that cardiovascular diseases are the number one cause of death globally. Working to address this imperative public health problem, researchers world-wide are seeking new ways to accelerate research, raise the accuracy of diagnoses and improve patient outcomes. Several initiatives have utilized ground-breaking new simulations to advance research into aspects such as rhythm disturbances and ...

Optimizing Application Energy Efficiency Using CPUs, GPUs and FPGAs

March 13, 2015 8:43 am | by Rob Farber | Comments

The HPC and enterprise communities are experiencing a paradigm shift as FLOPs per watt, rather than FLOPs (floating-point operations per second), are becoming the guiding metric in procurements, system design, and now application development. In short, “performance at any cost” is no longer viable, as the operational costs of supercomputer clusters are now on par with the acquisition cost of the hardware itself.

PNNL Shifts Computational Chemistry into Overdrive

February 25, 2015 8:29 am | by Karol Kowalski, Ph.D., and Edoardo Apra, Ph.D. | Comments

We computational chemists are an impatient lot. Despite the fact that we routinely deal with highly complicated chemical processes running on our laboratory’s equally complex HPC clusters, we want answers in minutes or hours, not days, months or even years. In many instances, that’s just not feasible; in fact, there are times when the magnitude of the problem simply exceeds the capabilities of the HPC resources available to us.

Seven Myths about Scientists Debunked

February 19, 2015 2:07 pm | by Jeffrey Craig and Marguerite Evans-Galea, Murdoch Childrens Research Institute | Comments

As scientific researchers, we are often surprised by some of the assumptions made about us by those outside our profession. So we put together a list of common myths we and our colleagues have heard anecdotally regarding scientific researchers.

Mars is the Next Step for Humanity – We Must Take It

February 18, 2015 9:40 am | by Ashley Dove-Jay, University of Bristol | Comments

Elon Musk has built a US$12 billion company in an endeavour to pave the way to Mars for humanity. He insists that Mars is a “long-term insurance policy” for “the light of consciousness” in the face of climate change, extinction events, and our recklessness with technology. On the other hand, astronaut Chris Hadfield is sceptical: “Humanity is not going extinct,” he told me.
