Hessian flies are overcoming wheat resistance genes in the southeastern U.S. — strategies in agricultural battles 0

If one anti-larval gene is not working anymore, pair two new ones in the same plant Researchers tested 21 of 33 commercial wheat resistance genes to see if they were still effective against Hessian fly larvae in the Southeast United States.  Only 5 of the 21 were, providing evidence that the genes were killing off [...]

Here’s a link to a beautiful (false color) astronomical photograph of bow shock in front of the star, Zeta Ophiuchi, as it speeds through space 0

NASA’s Wide-Field Infrared Survey Explorer renders some exquisite pictures of the universe Here’s one such, with a well-written caption explaining what is happening: http://www.nasa.gov/mission_pages/WISE/multimedia/gallery/pia13455.html

Van der Waals forces — recent progress in measurement and an excellent write-up in “ScienceDaily” 0

Van der Waals forces — a example of the importance of being weak and therefore indispensible Van der Waals forces literally keep life alive (as in allowing reasonably consistent protein folding) — despite being infinitesimally weak. They are a good example of how subtle, atomic-scale phenomena critically affect the macroscopic world that is only just [...]

Glacially-associated loess as an explanation for wealth of subsequently preserved, fine-detail fossils nearly one-half billion years old 0

This fossil preservation hypothesis is interesting Sarah E. Gabbott et al. explained the origins of a detailed bed of roughly 475 million year-old Late Ordovician fossils in South Africa. The group’s hypothesis gives us an excuse to consider the random-seeming origins of fossil records generally. Discussing the Soom Shale member of the Cedarberg Formation, the [...]

Bob Herbert’s tribute to Sargent Shriver — founder of the Peace Corps, Volunteers in Service to America, Head Start, and the Jobs Corps — is worth reading for the contrast Shriver’s life presents to today’s mostly self-involved figures 0

For those who think that most of us are recalcitrantly stupid, irrational, and misguidedly judgmental — here’s some more evidence for the proposition 0

First impressions carry a boatload of your future — and not just once ScienceDaily reported on experimental research by Bertram Gawronski et al.: “Imagine you have a new colleague at work and your impression of that person is not very favourable” explains lead author Bertram Gawronski, Canada Research Chair at The University of Western Ontario. [...]

Many plants apparently move downhill with climatic warming — opposite of what off-the-cuff thinking might predict 0

Not jumping to conclusions is a useful scientific trait Common sense leaves many of us thinking that climate warming would induce plant species habitats to move uphill, as their old location warms and they “seek” to escape increased temperature. Not so, says a University of California –Davis study of plant habitat locations during a period [...]

A good example of a mostly unscientific, statistically worthless medical study that may actually have some value — hydrolyzed gluten may avoid the negative effects that gluten has on celiac patients 0

Can a much too-short study of 11 patients say anything about anything? — Maybe anecdotally A 60-day study that began with 13 celiac disease patients and ended with 11 had this to say: Celiac disease (CD) is characterized by an inflammatory response to wheat gluten, rye, and barley proteins. . . . We evaluated the [...]

An estimated mortality rate of 42 percent in an outbreak of polio in the Republic of the Congo — Can this be accurate, and why haven’t we heard much about it? 0

Forgotten Africa Science reported at the end of December 2010: An explosive outbreak in the Republic of Congo is writing another chapter in the book on how this ancient scourge behaves. Polio usually strikes children under age 5, paralyzing one in 200 of those infected and killing at most 5%, occasionally up to 10% in [...]

Columnist Richard Cohen used two recent Obama speeches to predict the future — an interesting and probably accurate observation 0

Inspirational President in post-shooting Tucson — versus stand-offish Obama eulogizing diplomat Richard Holbrooke Columnist Richard Cohen compared the two speeches and hypothesized that the Holbrooke speech indicated that the President is not going to change his characteristic removed style: But when it came to the Holbrooke speech, imagination failed the president. He and Holbrooke did [...]
