As you might expect, much of the evolution of how lizards move is related to getting food.

A research team led by Ohio University doctoral student Eric McElroy tracked 18 different species of lizards as they walked or ran in order to understand how their foraging styles impact their biomechanics. The study, funded by the National Science Foundation, was featured in the April 1 edition of the Journal of Experimental Biology.

Lizards use two basic foraging techniques. In the first approach, aptly dubbed sit-and-wait, lizards spend most of their time perched in one location waiting for their prey to pass. Then, with a quick burst of speed, they run after their prey, snatching it up with their tongues.

A recent study by NOAA scientists and colleagues on captive juvenile sandbar sharks showed the presence of an electropositive alloy, in this case palladium neodymium, clearly altered the swimming patterns of individual animals and temporarily deterred feeding in groups of sharks.

Rare earth metals have previously been reported to deter spiny dogfish from attacking bait due to interactions with the shark’s electroreceptive system, which detects weak electric fields including those generated by their prey.

Electric fields generated by electropositive alloys are believed to deter or repel sharks by overloading their sensory systems, a behavior that may help fishery biologists develop a strategy to reduce the bycatch of sharks in longline gear. Shark bycatch is an increasing priority worldwide given diminished populations of many shark species, and because sharks compete with target species for baited lines, reducing fishing efficiency and increasing operating costs.

The residual herbicides commonly used in the production of corn and soybean are frequently detected in rivers, streams, and reservoirs at concentrations that exceed drinking water standards in areas where these crops are extensively grown.

When these bodies of water are used as sources of drinking water this contamination can lead to increased treatment costs or a need to seek alternative sources of supply. Additionally, these herbicides can have negative effects on aquatic ecosystems at concentrations well below their drinking water standards.

When genetically modified, herbicide-tolerant, corn and soybean became commercially available in the 1990s it became possible to replace some of the problematic residual herbicides with strongly sorbed, short half-life, contact herbicides that may be more environmentally benign. By 2004 almost 90% of the soybean grown in the US was genetically modified for tolerance to the contact herbicide glyphosate (Roundup), which is currently the most widely used herbicide in the world.

From the war room to the board room, negotiations are a part of everyday life. Successful negotiations demand a clear understanding of one’s opponent. But what approach should one take to achieve such an understanding of one’s opponent in everyday negotiations?

Psychologist Adam Galinsky from the Kellogg School of Management at Northwestern University, and colleagues William Maddux (INSEAD), Debra Gilin (St. Mary’s U.), and Judith White (Dartmouth) asked a similar question and found that success in negotiations depends on focusing on the head and not the heart. In other words, it is better to take the perspective of negotiation opponents rather than empathize with them.

Researchers at Deventer Hospital recently tried Luminol, a chemical used by crime scene investigators, to detect traces of blood in their haemodialysis unit. Luminol reacts with microscopic amounts of blood to produce bright blue luminescence, which allows investigators to track invisible blood splashes in the environment.

The researchers tested their apparently clean unit with Luminol and found traces of blood on many surfaces, including cupboard handles, telephones, computer keyboards, side tables and the floor, even though some of these surfaces had been cleaned. They expect that these results can be reproduced in other hospitals that plan to use Luminol in the future as described in their paper.

- International Climate Science Coalition Releases Signatories to the Manhattan Declaration on Climate Change

The International Climate Science Coalition (ICSC) today released the names of over 500 endorsers of the Manhattan Declaration on Climate Change that calls on world leaders to "reject the views expressed by the United Nations Intergovernmental Panel on Climate Change (IPCC) as well as popular, but misguided works such as 'An Inconvenient Truth'." All taxes, regulations, and other interventions intended to reduce emissions of carbon dioxide (CO2) should "be abandoned forthwith", declaration signatories conclude.

Score one for the nurture side of the nature vs. nurture debate, as North Carolina State University geneticists have shown that environmental factors such as lifestyle and geography play a large role in whether certain genes are turned on or off.

By studying gene expression of white blood cells in 46 Moroccan Amazighs, or Berbers – including desert nomads, mountain agrarians and coastal urban dwellers – the NC State researchers and collaborators in Morocco and the United States showed that up to one-third of genes are differentially expressed due to where and how the Moroccan Amazighs live.
