We know that healthy mitochondria, the energy factories of cells, rely on proper reduction and oxidation to keep us converting food to energy and staving off mitochondrial pathologies. Any number of compounds have been created to try and keep that going as we age. They determine whether cells live or die and they regulate inflammation.

If you grew up on a farm, you may have gotten sick lots of times due to exposure to any number of microorgansms. You might not remember getting sick more then, but a new study finds you are less likely to have chronic maladies as an adult.

New research conducted at Aarhus University finds that people who have grown up on a farm with livestock are only half as likely as urban counterparts to develop the most common inflammatory bowel diseases: ulcerative colitis and Crohn's disease.   

It's not a secret that groundwater levels in Texas have declined since the Dust Bowl era - the obvious reasons are what you expect - more population and more food grown to sustain them.

But there are other key contributing factors, and the news isn't all bad, according to a new analysis. The groundwater declines have been most severe in the past four decades, according to Dr. Srinivasulu Ale, Texas A&M  AgriLife Research geospatial hydrology assistant professor in Vernon. 

CAMBRIDGE, Mass-- Last year, MIT researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated that this process can generate small amounts of electricity that might be used to power electronic devices.

The new findings, by postdoc Nenad Miljkovic, associate professor of mechanical engineering Evelyn Wang, and two others, are published in the journal Applied Physics Letters.

This approach could lead to devices to charge cellphones or other electronics using just the humidity in the air. As a side benefit, the system could also produce clean water.

July 11, 2014 – The increased risk of kidney injury related to the use of hydroxyethyl starch (HES) in resuscitation fluids reflects the mass of HES molecules, according to a report in Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

The "total mass of HES molecules" explains the harmful effect of HES on cultured human renal proximal tubule cells (PTCs), concludes the laboratory study by Dr Christian Wunder and colleagues of University Hospital Würzburg, Austria. Other factors—such as differences in the origin or molecular weight of HES solutions—appear to play little or no role in cellular-level toxicity of HES.

What Factors Affect Toxic Effects of HES on Kidney Cells?

We all know what happens to us when we get sick, but at least we have a microbiota to protect us. What happens when those ecosystem bacteria colonizing our guts gets hit with infection?

A new computational models showed how infection can affect bacteria that naturally live in our intestines, which may help clinicians to better treat and prevent gastrointestinal infection and inflammation through a better understanding of the major alterations that occur when foreign bacteria disrupt the gut microbiota.

Pornography triggers brain activity in people with compulsive sexual behavior – sex addiction – similar to that triggered by drugs in the brains of drug addicts, according to new paper. 

One of your earliest science memories in school is learning that, during photosynthesis, plants take in carbon dioxide sunshine and produce oxygen. Later we all learned that in lakes and oceans a similar process happens due to cyanobacteria. 

What has remained unknown is exactly how that happens.

Oxygen formation in photosynthesis occurs in a reaction sequence that is completed within one thousandth of a second, so it's not surprising that it has been so difficult to prove experimentally how precisely a catalyst consisting of four manganese ions and one calcium ion (Mn4Ca cluster) performs this reaction sequence in photosystem II.

Imagine getting this text message when you are at the pub tonight: "Looking forward to seeing you at 2 AM - General Hospital".

Creepy, but it may work. 

Young adults who screened positive for a history of hazardous or binge drinking reduced their binge drinking by more than 50 percent after receiving mobile phone text messages following a visit to the emergency department, according to a new paper. 

In the process of revising a chapter of my book, I found a clip I would like to share here, as it contains an analogy I cooked up and which I find nice enough to be proud of. Well, two analogies, as you'll soon find out; here I am speaking of the cat weighing trouble at the end of the piece - the other is quite trivial.
The topic is the widely different masses of fermions, the building blocks of our universe, and the trouble in making sense of it and of measuring precisely their values. Comments welcome!
