It's no surprise that between 1880 and 1920, as the population increased and America became more settled, Missouri, Oklahoma and Arkansas had increased deforestation and that decreased the habitat for black bears and other forest species.

To remedy that and repopulate that mountainous region known as the Central Interior Highlands (CIH), more than 250 bears from Minnesota and Manitoba were relocated to Arkansas in the 1950s and 1960s. Researchers have analyzed genetic diversity in black bears in the 
the Central Interior Highlands
and determined that conservation management has worked, but bears are not out of the woods yet.

A variety of programs have been introduced in UK hospitals to reduce patient deaths over the past decade and Advancing Quality - imported from the United States - was first to demonstrate a significant reduction in patient deaths. 

It was introduced in the North West region of England in 2008 and Advancing Quality was found to have reduced patient deaths by 890 in the first 18 months of the policy's introduction.  

A new paper has found that two broad-spectrum systemic insecticides, fipornil and imidacloprid, may be impacting honeybees.

Fipronil, part of the phenylpyrazole chemical family, is a highly effective insecticide which can be applied at very low doses for everything from crop to veterinary pests. Imidacloprid is in the class of chemicals called neonicotinoids - it mimics nicotine, which can be toxic to sucking insects like fleas and termites but has no effect on mammals.
 

Tuber melanosporum - black or Périgord truffles - are fungi that grow in symbiosis with the roots of oak and hazelnut trees. In the world of haute cuisine, they are expensive and highly prized.

Epigenetics is the study of changes in gene expression caused by mechanisms other than changes in the DNA sequence.
In the world of epigenetics, black truffles are of major interest because of their unique pattern of DNA methylation, a biochemical process that chemically modifies nucleic acids without changing their sequence. 

A newly published reports on the truffle's unique genetic makeup.

Mercury is a naturally occurring element and a part of human enterprises like burning coal and making cement and compact fluorescent light bulbs.

Knowing how much of both natural and unnatural mercury is bioavailable - uptaken by animals and humans— is important in international agreements to protect humans and the environment from mercury emissions and establishing public policies behind warnings about seafood consumption. Yet little is known about how much mercury in the environment is the result of human activity, or even how much bioavailable mercury exists in the global ocean.

Wikipedia is a free, online, user-generated database of articles on topics and people. Because of its popularity, it has become the default first link in Google search, which means it is frequently read and cited, making it even more authoritative in Google search.

There are numerous problems with the veracity of content, deliberate vandalism and incomplete entries - the Science 2.0 entry, for example, has been repeatedly hijacked and reverted by one user and the first reference is from a Wired article written in 2012 even though Science 2.0 came into existence in 2006. There are no links to Science 2.0 and that user even refuses to allow mention that it is a registered trademark and in the US and the European Union.
