Qlucore Omics Explorer 3.1 for Mac is data analysis software designed to maximize the outcome of research by making it easy to analyze experiment data from a biological point-of-view. Examples of this are the inbuilt Gene Ontology (GO) Browser, a Gene Set Enrichment Analysis (GSEA) function, and freedom to explore data using any variable identifier: variable collapse.
A new study suggests that a novel DNA-peptide structure can be used to produce thin, transparent and flexible screens. The research harnesses bionanotechnology to emit a full range of colors in one pliable pixel layer — as opposed to the several rigid layers that constitute today's screens.
Big data: It’s a term we read and hear about often, but is hard to grasp. Computer scientists tackled some big data about an important protein and discovered its connection in human history as well as clues about its role in complex neurological diseases. Through a novel method of analyzing these big data, they discovered a region encompassing the gephyrin gene on chromosome 14 that underwent rapid evolution after splitting in two...
Fossil remains of a previously unknown species of a crocodile-like "super salamander" that grew as long as a small car and was a top predator more than 200 million years ago have been found in southern Portugal, researchers announced on March 24, 2015. The prehistoric species, which looked like giant salamanders, grew up to six feet in length and lived in lakes and rivers.
The intraterrestrials, they might be called. Strange creatures live in the deep sea, but few are odder than the viruses that inhabit deep ocean methane seeps and prey on single-celled microorganisms called archaea. The least understood of life's three primary domains, archaea thrive in the most extreme environments: near hot ocean rift vents, in acid mine drainage, in the saltiest of evaporation ponds and in petroleum deposits.
A newly discovered crocodilian ancestor may have filled one of North America's top predator roles before dinosaurs arrived on the continent. The "Carolina Butcher" was a nine-foot-long, land-dwelling crocodylomorph that walked on its hind legs and likely preyed upon smaller inhabitants of North Carolina ecosystems, such as armored reptiles and early mammal relatives.
Breakthrough science requires pioneers. People who combine brilliance with courage, even in the face of daunting opposition. The women who paved the way for modern scientific exploration exemplify this spirit; grappling not only with fundamental questions of the universe, but with discrimination and societal constraints that often stripped them of scientific credit.

Today’s health care system generates massive amounts of data — electronic health records, diagnostic imaging, prescriptions, genomic profiles, insurance records, even data from wearable devices. Information has always been essential for guiding care, but computer tools now make it possible to use that data to provide deeper insights. Leveraging big data to revolutionize healthcare is the focus of the Pittsburgh Health Data Alliance.
Researchers have developed a statistical technique that sorts out when changes to words’ pronunciations most likely occurred in the evolutionary history of related languages. Their model gives researchers a renewed opportunity to trace words and languages back to their earliest common ancestor or ancestors — potentially thousands of years further into prehistory than previous techniques.
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.
How can we preserve our knowledge today for the next millennia? Researchers have found a way to store information in the form of DNA, preserving it for nearly an eternity. As encapsulation in silica is roughly comparable to that in fossilized bones, researchers could draw on prehistoric information about long-term stability and calculate a prognosis: through storage in low temperatures, DNA-encoded information can survive.
The sequencing machines that run today produce data several orders of magnitude faster than the machines used in the Human Genome Project. We at the Wellcome Trust Sanger Institute currently produce more sequences in one hour than we did in our first 10 years of operation. A great deal of computational resource is then needed to process that data.
For those on the front lines of treating cancer, speed and precision are key to patients’ survival. Pediatric cancer researchers have been making incredible strides in accelerating delivery of new diagnostic and treatment options. Supercomputer-powered genetic diagnosis is being used to harness the power of high throughput genomic and proteomic methods and is playing a key role in improving the outcome for children with genetic diseases.
Rare diseases — those that affect fewer than one in 200,000 people — are often identified early in life. Some 30 percent of children afflicted by these "orphan diseases" do not live to see their fifth birthday. While the US Orphan Drug Act of 1983 was written into law to promote research on the topic, the cost of identifying the source and progression of these diseases remains prohibitive for many families.
Scientists have identified a biological clock that provides vital clues about how long a person is likely to live. Researchers studied chemical changes to DNA that take place over a lifetime, and can help them predict an individual's age. By comparing individuals’ actual ages with their predicted biological clock age, scientists saw a pattern emerging.
The release of the film, Still Alice, in September 2014 placed a much-needed light on Alzheimer's disease, a debilitating neurological disease that affects a growing number of Americans each year. More than 5.2 million people in the U.S. are currently living with Alzheimer's. One out of nine Americans over 65 has Alzheimer's, and one out of three over 85 has the disease. For those over 65, it is the fifth leading cause of death.
Diabesity has been identified as a major global health problem by researchers and healthcare professionals world-wide, including England’s National Health Service, Brigham and Women’s Hospital and Harvard Medical School, Ain Shams University Hospital in Cairo, Egypt, and a research consortium of the European Union.
Researchers have cracked a code that governs infections by a major group of viruses, including the common cold and polio. The unnoticed code had been hidden in plain sight in the sequence of the ribonucleic acid (RNA) that makes up this type of viral genome. But researchers have unlocked its meaning and demonstrated that jamming the code can disrupt virus assembly. Stopping a virus assembling can stop it functioning.
Cancer researchers must use one of the world's fastest computers to detect which versions of genes are only found in cancer cells. Every form of cancer, even every tumor, has its own distinct variants. A research group is working to identify the genes that cause bowel and prostate cancer, which are both common diseases. There are 4,000 new cases of bowel cancer in Norway every year. Only six out of 10 patients survive the first five years.
Scientists using supercomputers found genes sensitive to cold and drought in a plant help it survive climate change. The computational challenges were daunting, involving thousands of individual strains of the plant with hundreds of thousands of markers across the genome and testing for a dozen environmental variables. Their findings increase basic understanding of plant adaptation and can be applied to improve crops.
A new online resource, called the Biosurveillance Gateway, is in place at Los Alamos National Laboratory, providing a centralized portal for all news, information, resources and research related to biosurveillance at the laboratory. The goal of the site is to support global disease surveillance, providing useful tools for professionals around the world to reference from a single location.
Scientists have taken a new path in the research into causes of epilepsy: They determined the networks of the active genes and — like a dragnet — looked for the "main perpetrators" using a computer model. In doing so, they discovered the molecule sestrin-3 as a central switch. In animal models, the scientists were able to demonstrate that inhibition of sestrin-3 leads to a reduction in seizures.
A team of scientists has received a $1.4 million grant from the National Science Foundation to help meet the growing needs of the data-driven genomic science community. The Tripal Gateway project will build on existing cyberinfrastructure to enhance the capacity of genomic databases to manage, exchange and process “big data.”

In the largest collaborative study of the brain to date, researchers from the Keck School of Medicine of the University of Southern California (USC) led a global consortium of 190 institutions to identify eight common genetic mutations that appear to age the brain an average of three years. The discovery could lead to targeted therapies and interventions for Alzheimer’s disease, autism and other neurological conditions.
