Surface-dwelling algae adjust their biochemistry to surface temperatures. As they die and sink to the bottom, they build a sedimentary record of sea-surface temperature across millennia. Brown’s work on surface temperatures, coupled with work from Texas A&M on rainfall and weather patterns, has helped chart the wetter, lake-filled geological history of the currently arid American West.

At least when it comes to female politicians, perhaps you can judge a book by its cover, suggest two UCLA researchers who looked at facial features and political stances in the U.S. House of Representatives. (more…)
An international group of scientists, including researchers from the Woods Hole Oceanographic Institution, are working to improve communication about ocean acidification to help the public better understand the pressing global issue.
The term “ocean acidification” (OA) describes the changes that occur in the ocean as a result of increased emissions of carbon dioxide (CO2) into the atmosphere. The rising acidic level in the ocean puts certain organisms at risk and threatens the overall health of the ocean. (more…)
ANN ARBOR, Mich.— Texting while driving is a serious threat to public safety, but a new University of Michigan study suggests that we might not be aware of our actions.
U-M researchers found that texting while driving is predicted by a person’s level of “habit”—more so than how much someone texts.
When people check their cell phones without thinking about it, the habit represents a type of automatic behavior, or automaticity, the researchers say. Automaticity, which was the key variable in the study, is triggered by situational cues and lacks control, awareness, intention and attention. (more…)

The theatrical history of London’s West End stretches more than three and a half centuries. The first theatre in this area of London, the Theatre Royal opened in 1663 and housed small productions until it was destroyed by fire some years later. While still mainly a pastime of the aristocracy, appreciation for theatre was widespread. Productions occurred in courtyards of public houses, in churches and in small parks for all to enjoy.
In 1843 the passage of the Theatres Act allowed for more theatres to be established in the West End. Several of the venues you pass on the street in what the locals affectionately call “Theatreland” today were part of this movement. (more…)
Paper describes new method to understand sources of noise in gene-expression
Abhyudai Singh, assistant professor of electrical and computer engineering at the University of Delaware, describes a new method to understand sources of “noise” in gene-expression that create variability in protein levels in a paper published in Molecular Systems Biology, a publication of Nature, on Aug. 28.
This noise is expressed as variability in the levels of proteins/mRNAs in a cell. (more…)
There is evidence that some microbial life had migrated from the Earth’s oceans to land by 2.75 billion years ago, though many scientists believe such land-based life was limited because the ozone layer that shields against ultraviolet radiation did not form until hundreds of millions years later.
But new research from the University of Washington suggests that early microbes might have been widespread on land, producing oxygen and weathering pyrite, an iron sulfide mineral, which released sulfur and molybdenum into the oceans. (more…)
