Big Data Analysis Reveals Shared Genetic Code between Species

December 18, 2014 11:32 am | by Mike Williams, Rice University | News | Comments

Researchers have detected at least three instances of cross-species mating that likely influenced the evolutionary paths of “old world” mice, two in recent times and one in the distant past. They think these instances of introgressive hybridization are only the first of many needles waiting to be found in a very large genetic haystack. The finding suggests that hybridization in mammals may not be an evolutionary dead end.

Exploration and Analysis of DNA Microarray and Other High-Dimensional Data

November 18, 2014 3:10 pm | by John A. Wass, Ph.D. | Articles | Comments

The introduction of newer sequencing methodologies, DNA microarrays and high-throughput technology has resulted in a deluge of large data sets that require new strategies to clean, normalize and analyze the data. All of these and more are covered in approximately 300 pages with extraordinary clarity and minimal mathematics.

Applications for Randomness

November 17, 2014 8:49 am | by Mark Anawis | Blogs | Comments

The mathematician, Robert R. Coveyou, said: “The generation of random numbers is too important to be left to chance.” Random numbers are used in sampling, simulations, modeling, data encryption, gambling and even musical composition. A random number is one selected from a set of equally possible values. Any sequence of random numbers must be statistically independent of the others.

JMP 11: Remarkable Statistics, Graphics and Integration

November 7, 2014 10:30 am | by John A. Wass, Ph.D. | Articles | Comments

It should come as no surprise to readers of this column that JMP is a personal favorite and, along with SAS, one of my most-used programs. There are a number of reasons for this. Of the many advantages that most packages can offer, breadth and depth of the statistics offered, quality of the diagnostics, interconnectivity of graphics with both data and analyses, and ease-of-use issues are uppermost in my mind as most desirable.

Time Machine Reveals Global Precipitation Role in Major Weather Events

October 16, 2014 2:53 pm | by Michael Price, San Diego State University | News | Comments

During the 1930s, North America endured the Dust Bowl, a prolonged era of dryness that withered crops and dramatically altered where the population settled. Land-based precipitation records from the years leading up to the Dust Bowl are consistent with the telltale drying-out period associated with a persistent dry weather pattern, but they can’t explain why the drought was so pronounced and long-lasting.

Solar Explosions inside a Computer: Predicting Solar Flares

Strong solar flares can bring down communications and power grids on Earth. By demonstrating how these gigantic eruptions are caused, physicists are laying the foundations for future predictions. The shorter the interval between two explosions in the solar atmosphere, the more likely it is that the second flare will be stronger than the first one.

Fluid Mechanics: New Math Suggests Alternative to Quantum Orthodoxy

September 15, 2014 3:43 pm | by Larry Hardesty, MIT | News | Comments

The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum has been what’s called the “Copenhagen interpretation” — which holds that, in some sense, a single particle really is a wave, smeared out across the universe, which collapses into a determinate location only when observed.

Scientists say Ozone Layer is Recovering

September 10, 2014 4:17 pm | by Seth Borenstein, AP Science Writer | News | Comments

Earth's protective but fragile ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. scientific panel reported September 10, 2014, in a rare piece of good news about the health of the planet. Scientists said the development demonstrates that, when the world comes together, it can counteract a brewing ecological crisis.

Discovering a brain tumor is a very serious issue, but it is not the end of the story. There are many different types of brain tumor with different survival rates and different methods for treatment. However, today, many brain tumors are difficult to clearly diagnose, leading to poor prognoses for patients.
