Salt-loving, halophilic, microbes could donate proteins to clean up radioactive strontium and caesium ions from the Fukushima Dai-ichi Nuclear Power Plant incident in Japan.

The X-ray structure of a beta-lactamase enzyme from one such microbe, the halophile Chromohalobacter sp. 560, shows it has highly selective cesium binding sites.  A 1.8 to 2.9 angstrom resolution structure for this enzyme. Anomalous X-ray diffraction also revealed binding sites in the protein for Sr2+ and Cs+ ions, the team reports.

We are all populated by microbes – helpful or otherwise – which form a community known as a microbiome. Recent research by Ryan Newton and co-workers has shown that sewage-based analysis of the human microbiome can be used to diagnose health issues at a population level.

Statins are associated with increased risk for diabetes, though it is unclear why. One hypothesis is that statins increase expression of LDL receptors and increase cholesterol uptake into cells including the pancreas, which could cause pancreatic dysfunction. Familial hypercholesterolemia causes decreased LDL transport into cells and researchers have hypothesized that with familial hypercholesterolemia, decreased pancreatic LDL transport would lessen cell death and ultimately lead to lower rates of diabetes.  

We may idealize the last century but natural forces have always caused climate on Earth to fluctuate - sometimes quite a bit. But science is about controlling nature and not letting random behavior control our destinies and since we know that some periods were good and some awful, we'd like to avoid the awful.

We can't control everything - the earth is still going to orbit the sun and such orbital forcing of climate change happens over thousands of years and brings ice ages and warming periods. 

Many mammals, and some birds, escape the winter by hibernating for three to nine months. This period of dormancy permits species which would otherwise perish from the cold and scarce food to survive to see another spring.

The Middle East, with temperate winters, was until recently considered an unlikely host for hibernating mammals.

Though every month we read about some new advance in artificial intelligence, how much progress is really being made?  Neuromorphic computing has created software and electronic hardware that mimic brain functions and signal protocols but, like economic models that successfully predict the past, they have only slightly improved the efficiency and adaptability of conventional technology and are not really making bold advances. 

Male partners of infertile obese females may increase the odds of conceiving a child by improving their own weight and dietary habits, preliminary results from a pilot study from Canada suggest. The results will be presented Thursday, March 5, at ENDO 2015, the annual meeting of the Endocrine Society in San Diego.

Since they were pioneered by Robert Hooke 350 years ago, microscopes have been extending our vision. In the 21st century, scanning electron microscopy (SEM) and confocal microscopy, which uses a pinhole to remove out-of-focus light and allows 3D structures to be built from multiple images, have pushed the boundaries of resolution.

In this country, poor diet, obesity and high rates of smoking have compounded to give nearly 75 percent of adults poor cardiovascular health.

It's not the United States, it is China, yet an alarming number of health plans promoted by American nutrition pundits advocate Asian lifestyles. 

The 2010 China Noncommunicable Disease Surveillance Group collected cardiovascular health data from a nationally representative sample of more than 96,000 men and women in the general Chinese population.

When there’s a report in the news about the latest science on climate change, the source is very often the United Nations Intergovernmental Panel on Climate Change.

This body plays a very important role in global climate change policy around the world. Its reports, five of which have been published since 1990, enjoy a degree of credibility that renders them influential for public opinion. And more important, the reports are accepted as the definitive source by international negotiators working under the United Nations Framework Convention on Climate Change (UNFCCC).
