Newspaper web ads not to blame for print advertising decline

ANN ARBOR — An open question as the newspaper industry struggles with declining revenues and profits is whether online ads cannibalize print advertising.

New research from S. Sriram, assistant professor of marketing at the University of Michigan Ross School of Business, finds that’s not the case. Analyzing five years of data from a top newspaper showed less than 8 percent of the print advertising decline was due to a shift to online ads on the paper’s website. (more…)

UCLA scientist uncovers biological clock able to measure age of most human tissues

Study finds women’s breast tissue ages faster than the rest of the body

Everyone grows older, but scientists don’t really understand why. Now a UCLA study has uncovered a biological clock embedded in our genomes that may shed light on why our bodies age and how we can slow the process.

Published in the Oct. 21 edition of the journal Genome Biology, the findings could offer valuable insights to benefit cancer and stem cell research. (more…)

UW work contributes to largest international study of Alzheimer’s genes

Eleven regions of the human genome have been newly discovered to influence the onset of Alzheimer’s disease. The findings stem from the largest international study ever conducted on this disorder, which causes gradual memory loss and other forms of cognitive decline in older people.

As of 2009, 10 genes were known to be related to Alzheimer’s, the result of about a quarter-century of research. Yet the reasons behind individual susceptibility or resistance to the disease continued to be poorly understood.  In February of 2011, four international research groups studying Alzheimer’s disease genetics united to more quickly identify other genes related to the disorder.

The People’s Choice: Americans Would Pay to Help Monarch Butterflies

Americans place high value on butterfly royalty. A recent study suggests they are willing to support monarch butterfly conservation at high levels, up to about 6 ½ billion dollars if extrapolated to all U.S. households.

If even a small percentage of the population acted upon this reported willingness, the cumulative effort would likely translate into a large, untapped potential for conservation of the iconic butterfly. (more…)

Bodenlose Verluste

Erosion vernichtet jährlich 24 Milliarden Tonnen Boden. / WWF warnt vor massiven Verlust fruchtbarer Agrarflächen.

Fruchtbarer Boden ist die wortwörtliche Grundlage unserer Ernährung. Trotzdem gehen jährlich weltweit mehr als 24 Milliarden Tonnen durch Erosion verloren. Davor warnt die Umweltschutzorganisation WWF anlässlich einer Konferenz zum Schutz fruchtbarer Böden in Berlin. „Die Menschheit zieht sich selbst den Boden unter den Füßen weg“, sagt Birgit Wilhelm WWF-Landwirtschaftsreferentin. Dabei seien fruchtbare Anbauflächen Grundvoraussetzung für 90 Prozent aller Lebensmittel – und nicht unendlich vorhanden. Laut Schätzungen bestehen nur zwölf Prozent der Erdoberfläche aus landwirtschaftlich nutzbarem Boden. Ist die gerade einmal 2,5 cm dicke fruchtbare Oberschicht durch Erosion verloren, dauert es 500 Jahre, um sie zurück zu bringen. (more…)
