The DZERO experiment is one of the two multi-purpose detectors that have collected 1.96 TeV proton-antiproton collisions at the Fermilab Tevatron collider until two years ago, when the machine was decommissioned.

Experiments of this kind out-live the demise of the hardware, since the extraction of precise physics measurements from the large datasets accumulated may take several years to complete. And in fact, it is not a surprise to see two new preprints in the Arxiv (here and here) which describe in detail the experimental techniques that the collaboration uses to extract jet physics results from the data.

While the number of killing frosts in southern Florida has remained unchanged since 1984, the number a short distance away declined enough that researchers are implicating global warming, and noted that the expansion of cold-sensitive mangrove forests along Florida's Atlantic Coast has led to them edging out salt marshes.

What happens when one ecosystem replaces another? Happens all of the time, of course, and has throughout history. But it's impossible to predict the result. People who live there are not complaining, though researchers up north are concerned.

An analysis from the University of Colorado School of Medicine shows patients with Medicaid insurance seeking care in an emergency department may be driven by lack of alternatives instead of the severity of their illness.

With the implementation of the Affordable Care Act, millions of new patients will be enrolled in Medicaid and added to an already overburdened primary care system. 

When it comes to the brain, there is very little science. fMRI imaging is subjective and pop psychology concepts even more so. Even when it comes to medical conditions, like schizophrenia, little is known. Its causes are unknown, there there is no objective test for it, and its diagnosis is based on an assortment of reported symptoms - and symptom-based diagnosis got replaced in most of medicine by the 1950s. The standard treatment, anti-psychotic medication, works less in less than half of those with a diagnosis and becomes increasingly ineffective over time.

By the time they turn two, most children have had respiratory syncytial virus (RSV) and suffered symptoms no worse than a bad cold.

Yet for some children, especially premature babies and those with underlying health conditions, RSV can lead to pneumonia and bronchitis, hospitalization and have long-term consequences.

Part 1, ‘Generative Text Generation’

Daniel Shiffman  is Assistant Arts Professor at the Interactive Telecommunications Program at NYU’s Tisch School of the Arts.

The professor has developed a Markov chain-based Generative Text computer programme which he describes (and provides the code for) here. The programme is able to generate English text which appears at first glance to make sense, but in reality has more in common with ‘context-free-grammar’ or, as some might say, gibberish.

I'm sorry I've been away so long:  The "press of life" got the "better of me".  Sometimes, life just "gets in the way".  (No excuses.  I simply had other "things" that needed to take priority.  Unfortunately, I don't see that changing any time soon.  So, unfortunately, I cannot promise to have an especially active presence here for the foreseeable future.)

[Note:  Since the creation of footnotes and cross references can be so tedious on this site, I shall go ahead and publish this version of this article without such, at first.  However, I shall endeavor to add such in as I can find the time.  I apologize for the lack of "polish" or completeness this will produce, at this time, but feel it will help me get this out to you in a more timely mann

If you have been to a tomato farm, you know that commercial tomato plants have a very different look from the backyard garden variety. Rather than being tall and lanky plants, tomatoes that will be canned for sauces and juice are harvested from plants that stop growing earlier than classic tomato varieties and are more like bushes. The architecture of these compact bushy plants allows mechanical harvesters to reap the crop, but the early end of growth means that each plant produces fewer fruits than their home garden cousins.

The federal government's proposal to discontinue protection for the gray wolf across the United States could have the unintended consequence of endangering other species, insist academics who don't actually live in places where wolves are running wild, threatening animals and people.

In the last few years it became popular to sell health books blaming fructose for obesity and, more recently, to blame all sugars. Pancake syrup bottle today highlight that they have no high fructose corn syrup on giant labels, while the first ingredient is still corn syrup - which is still fructose, just in random rather than precise amounts.

A new study found that fructose does not have any impact on an emerging marker for the risk of cardiovascular disease known as postprandial triglycerides - beyond the general impact of eating a lot of calories, anyway, but that applies to all foods.
