Tropical rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen.
But the amount of carbon dioxide that rainforests absorb, or produce, varies hugely with year-to-year variations in the climate.
In a paper published online (Feb 6 2013) by the journal Nature, a team of climate scientists from the University of Exeter, the Met Office-Hadley Centre and the NERC Centre for Ecology & Hydrology, has shown that these variations reveal how vulnerable the rainforest is to climate change. (more…)
Work-related stress is not directly linked to the development of colorectal, lung, breast or prostate cancers, but can cause other contributing factors, according to a new study published on bmj.com(more…)
Jay Dickson and Jim Head have gathered time-lapse photography and other data about the sustained salinity of Antarctica’s Don Juan Pond, the most saline natural body of water on earth. Their findings, published online in Scientific Reports, suggest that such ponds could be possible on Mars.
PROVIDENCE, R.I. [Brown University] — Antarctica’s Don Juan Pond might be the unlikeliest body of water on Earth. Situated in the frigid McMurdo Dry Valleys, only the pond’s high salt content — by far the highest of any body of water on the planet — keeps it from freezing into oblivion. (more…)
A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has discovered that microscopic bacteria have a lot in common with earthquakes — when it comes to their jolting movements.
In a new study published in the peer-reviewed Proceedings of the National Academy of Sciences, the scientists also report that a molecular “glue” produced by the bacteria to help them adhere to surfaces also acts as a sort of transportation lubricant, helping them move and organize into rudimentary social structures. These discoveries, they say, could lead to new ways to combat harmful microbes in the long term. (more…)
Microsoft partners Infusion, BlueGranite and Neudesic weigh in on how they use big data to shape their business strategy.
REDMOND, Wash. – Feb. 13, 2013 – IT departments are being overrun with big data – gigabytes, terabytes, petabytes of data – that is racing through their servers, often untamed and uncontrolled, with more data crowding onto the IT network every day, every hour.
While businesses can choose to keep all this data penned up, they are missing an opportunity to mine valuable business intelligence from their big data unless they harness it and analyze the information they have corralled, using that insight to gain a competitive edge. While a portion of this big data is well-organized information on products and finances, much of it is unstructured, from social media posts and photos to disparate research findings and customer feedback.

Discovery resulted from study of amphibians in ponds
The richer the assortment of amphibian species in a pond, the more protection that community of frogs, toads and salamanders has against a parasitic infection that can cause severe deformities, including the growth of extra legs.
The findings, published in a paper in this week’s issue of the journal Nature, support the idea that greater biodiversity in large-scale ecosystems, such as forests or grasslands, may also provide greater protection against diseases, including those that affect humans.
A larger number of mammal species in an area may curb cases of Lyme disease, while a larger number of bird species may slow the spread of West Nile virus. (more…)
Corporate managers widely exposed to more than one culture during their formative years (up until 23 years of age) are more likely to be confident taking difficult and risky decisions, such as acquisitions, new research from the University of Exeter Business School reveals.
The study looked at over 2,000 acquisition decisions taken by board members at 561 UK listed companies, and found that managers who live or study in cultures other than their own more readily take difficult strategic decisions such as deciding to acquire foreign companies.
Co-author, Grzegorz Trojanowski, Associate Professor in Finance at the University of Exeter Business School says corporate managers with wide exposure to different cultures tend to see doing business in foreign countries as providing great opportunities, and they expect to get a positive result from their business activities in these markets.

Researchers have discovered four previously unknown viruses that infect the Earth’s most abundant organism, the marine bacterium SAR11. Because of their huge numbers, these tiny players have critical roles in the global cycle of carbon and other nutrients.
The greatest battle in Earth’s history has been going on for hundreds of millions of years, isn’t over yet, and until now no one knew it existed, scientists reported today in the journal Nature.
In one corner is the Earth’s most abundant organism: SAR11, an ocean-living bacterium that survives where most other cells would die and plays a major role in the planet’s carbon cycle. It had been theorized that SAR11 was so small and widespread that it must be invulnerable to attack. (more…)
