With all of the recent controversy about claims that Monsanto funding a plant biologist skewed discussion by scientists in their favor, and claims that organic PR companies strategically used anti-science activists at Mother Jones and the New York Times to keep those readers against GMOs, a public relations study couldn't be more timely.

Americans lead the world in adult science literacy, just like America leads the world in science output, but there are substantial differences among Americans when it comes to knowledge and understanding of science topics.

The details beyond the averages are important and while numerous pundits will lament that everyone does not know everything, that is not realistic. What is important is that as many people as possible have access to knowledge.

Patients with spinal stenosis (SS) experienced good short term benefit, lasting from weeks to months, after receiving epidural steroid injections (ESI).

These findings, which appear in a letter in the journal Pain Medicine, contradict a previously published New England Journal Medicine (NEJM) study that found epidural steroid injections were not helpful in spinal stenosis cases.

New research has uncovered why a particular strain of Staphylococcus aureus -- known as HA-MRSA -- becomes more deadly than other variations. These new findings open up possible new pathways to vaccine development against this bacterium, which the Centers for Disease Control and Preventions says accounts for over 10,000 deaths annually, mostly among hospital patients.

In a series of experiments in mice and in human immune cells in the lab, a team found that the presence or absence of dueling toxins, or bacterial poisons, appears to explain the major difference between HA-MRSA, and its less virulent and more common, community based-based cousin, CA-MRSA, the two main types of MRSA infection.

As you all know, the ecosystem is like a giant human anti-lung - it breathes in the CO2 we exhale and helps produce oxygen.

It turns out that the Southern Ocean seasonally absorbs significantly more CO2 than they release, higher than previous estimates. Most importantly, these seas remove a large part of the CO2 that human activities emit into the atmosphere, thereby slowing down the growth of this greenhouse gas in the atmosphere, which has been lessening the rate of climate change.

Working in a cave complex deep beneath South Africa's Malmani dolomites, an international team of scientists has brought to light an unprecedented trove of hominin fossils -- more than 1,500 well-preserved bones and teeth -- representing the largest, most complete set of such remains found to date in Africa.

The discovery of the fossils, cached in a barely accessible chamber in a subterranean labyrinth not far from Johannesburg, adds a new branch to the human family tree, a creature dubbed Homo naledi.

The remains, scientists believe, could only have been deliberately placed in the cave.
