Study part of growing body of knowledge surrounding gene-environment interplay

TORONTO, ON – It is time to put the nature versus nurture debate to rest and embrace growing evidence that it is the interaction between biology and environment in early life that influences human development, according to a series of studies recently published in a special edition of the Proceedings of the National Academy of Sciences (PNAS).

“Biologists used to think that our differences are pre-programmed in our genes, while psychologists argued that babies are born with a blank slate and their experience writes on it to shape them into the adults they become. Instead, the important question to be asking is, ‘How is our experience in early life getting embedded in our biology?’” says University of Toronto behavioural geneticist Marla Sokolowski. She is co-editor of the PNAS special edition titled “Biological Embedding of Early Social Adversity: From Fruit Flies to Kindergarteners” along with professors Tom Boyce (University of British Columbia) and Gene Robinson (University of Illinois).

Wolfgang Fink of the University of Arizona department of electrical and computer engineering has developed an autonomous robotic lake lander that could be used to explore this planet and others.

Fink unveiled the lake lander, named Tucson Explorer II, or TEX II, in a paper titled “Robotic Lake Lander Test Bed for Autonomous Surface and Subsurface Exploration of Titan Lakes,” which he presented March 8 at an aerospace conference organized by the Institute of Electrical and Electronics Engineers in Big Sky, Mont.

University of Arizona College of Engineering professor Wolfgang Fink has been elected to the College of Fellows of the American Institute for Medical and Biological Engineering.

Fink is an associate professor in the UA department of electrical and computer engineering, where he is the founding director of the Visual and Autonomous Exploration Systems Research Laboratory and holds the Edward and Maria Keonjian Endowed Chair. Fink also has joint appointments in the departments of biomedical engineering, systems and industrial engineering, and ophthalmology and vision science. (more…)

NASA Mars Rover Approaches Long-Term Goal

The NASA Mars rover Opportunity has gained a view of Endeavour crater from barely more than a football-field’s distance away from the rim. The rim of Endeavour has been the mission’s long-term goal since mid-2008.

Endeavour offers the setting for plenty of productive work by Opportunity. The crater is 14 miles (22 kilometers) in diameter — more than 25 times wider than Victoria crater, an earlier stop that Opportunity examined for two years. Observations by orbiting spacecraft indicate that the ridges along Endeavour’s western rim expose rock outcrops older than any Opportunity has seen so far. The selected location for arrival at the rim, “Spirit Point,” is at the southern tip of one of those ridges, “Cape York,” on the western side of Endeavour. (more…)
