2:57 PM | AP39: Fart Smell Compound May Prevent Diabetes, Heart Attacks And Dementia
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.read more

2:30 PM | Hygiene Hypothesis? Growing Up On A Farm Halves The Risk Of Inflammatory Bowel Diseases
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.

6:32 AM | Little Discussed Reasons For Groundwater Table Declines In Texas
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. read more

6:25 AM | Night-to-night variability of sleep in TBI
It's been a while since I've posted something substantial. My apologies to all 20 followers of TQLC. Academia and clinical cases have been taking up most of my time. However, some exciting news! My paper on variability of respiration during sleep in TBI has recently been accepted into Neurorehabilitation. In the paper my colleagues and I examined the sleep processes of individuals with TBI using polysomnography. Polysomnography is a tool used to measure biophysical changes during […]

4:15 AM | Getting A Charge Out Of Water Droplets
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 […]

4:15 AM | In Lab Studies, Hydroxyethyl Starch Has Direct Harmful Effects On Kidney Cells
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 […]

11:31 PM | Sometimes Good Gut Bacteria Get Sick
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 […]

5:48 PM | Researchers Catch Photosynthesis Oxygen Formation In Action
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 […]

1:39 PM | Self Quote Of The Week: Why You Can't Weigh Quarks Directly
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. […]
