To Save Water on Lawns, Throw Some Shade

How much water does your lawn really need? A University of Utah study re-evaluated lawn watering recommendations by measuring water use by lawns in Los Angeles. The standard model of turfgrass water needs, they found, lacked precision in some common urban southern California conditions, like the Santa Ana winds, or in the shade.

Understanding Tourists’ Preferences for Nature-Based Experiences May Help with Conservation

Charismatic species—such as felines and primates or whales, sharks, and turtles—are attractive to tourists, and the opportunity of seeing them in the wild motivates tourists to visit protected areas. New research indicates that tourists’ preferences are not restricted to charismatic species, however, and they extend to less charismatic biodiversity, as well as to landscapes.

New Clues About the Aging Brain's Memory Functions

118701_web.jpg

A European study led by Umeå University Professor Lars Nyberg, has shown that the dopamine D2 receptor is linked to the long-term episodic memory, which function often reduces with age and due to dementia. This new insight can contribute to the understanding of why some but not others are affected by memory impairment. The results have been published in the journal PNAS.

World's First Successful Artificial Insemination of Southern Rockhopper Penguin

118596_web.jpg

DNA tests have confirmed that one of the three southern rockhopper penguin chicks born at Osaka Aquarium Kaiyukan between June 4 and 6 was conceived through artificial insemination. This is the result of a project led by Kaiyukan with the collaboration of Associate Professor KUSUNOKI Hiroshi (Kobe University Graduate School of Agricultural Science). It is the world's first successful case of a southern rockhopper penguin being conceived through artificial insemination.

Honeybee Circadian Rhythms Are Affected More by Social Interactions

Circadian rhythms are internal clocks that determine many of an organism's daily rhythms, for example sleep-wake, feeding, urinary output and hormone production. Aligned with the environment by external forces such as sunlight and ambient temperature, circadian rhythms are important for animal health and survival. Disturbances of the circadian clock are associated with a variety of diseases in humans and animals, including cancer, mental illnesses and metabolic disorders, such as diabetes and obesity.

New Analysis Reveals Large-Scale Motion Around San Andreas Fault System

117953_web.jpg

An array of GPS instruments near the San Andreas Fault System in Southern California detects constant motion of Earth's crust--sometimes large, sudden motion during an earthquake and often subtle, creeping motion. By carefully analyzing the data recorded by the EarthScope Plate Boundary Observatory's GPS array researchers from the University of Hawai'i at Mānoa (UHM), University of Washington and Scripps Institution of Oceanography (SIO) discovered nearly 125 mile-wide "lobes" of uplift and subsidence--a few millimeters of motion each year--straddling the fault system. This large scale motion was previously predicted in models but until now had not been documented.
