Parents can use knowledge to help steer teens through life changes

COLUMBIA, Mo. — During adolescence, the stories young people tell about themselves reflects their development of a personal identity and sense of self, and those autobiographical narratives vary depending on the teens’ gender, according to a University of Missouri psychologist and her colleagues. Parents can use this knowledge of how teens talk about themselves to help understand the tumultuous transitions of their children into adults.

“Autobiographical stories tell us details about adolescent psychology that questionnaires and observations of behavior cannot,” said Jennifer Bohanek, assistant professor of psychological sciences in the College of Arts and Science. “Narratives provide information about how adolescents interpret memories as well as how they come to know themselves. Other people then come to know the teens by the stories they tell about themselves. The differences between study participants’ stories suggest there may be differences in the way male and female teens understand themselves and present themselves to the world.” (more…)

Human Impact Felt on Black Sea Long Before Industrial Era

When WHOI geologist Liviu Giosan first reconstructed the history of how the Danube River built its delta, he was presented with a puzzle.

In the delta’s early stages of development, the river deposited its sediment within a protected bay. As the delta expanded onto the Black Sea shelf in the late Holocene and was exposed to greater waves and currents, rather than seeing the decline in sediment storage that he expected, Giosan found the opposite. The delta continued to grow. In fact, it has tripled its storage rate. (more…)

UCLA researchers have discovered a type of cell that is the “missing link” between bone marrow stem cells and all the cells of the human immune system, a finding that will lead to a greater understanding of how a healthy immune system is produced and how disease can lead to poor immune function.

The research was done using human bone marrow, which contains all the stem cells that produce blood during post-natal life. (more…)

Witch Hunts Targeted by Grassroots Women’s Groups

EAST LANSING, Mich. — Witch hunts are common and sometimes deadly in the tea plantations of Jalpaiguri, India. But a surprising source – small groups of women who meet through a government loan program – has achieved some success in preventing the longstanding practice, a Michigan State University sociologist found.

Soma Chaudhuri spent seven months studying witch hunts in her native India and discovered that the economic self-help groups have made it part of their agenda to defend their fellow plantation workers against the hunts. (more…)

The Pink Double Dandy peony, the Double Peppermint petunia, the Doubled Strawberry Vanilla lily and nearly all roses are varieties cultivated for their double flowers.

The blossoms of these and other such plants are lush with extra petals in place of the parts of the flower needed for sexual reproduction and seed production, meaning double flowers – though beautiful – are mutants and usually sterile.

The genetic interruption that causes that mutation helped scientists in the 1990s pinpoint the genes responsible for normal development of sexual organs stamens and carpels in the plant Arabidopsis thaliana, long used as a plant model by biologists. (more…)

On The Front Lines

UD scientist sees Arctic ice loss firsthand

The extent of sea ice in the Arctic has reached a record low, according to data released Aug. 26 by the U.S. National Snow and Ice Data Center (NSIDC).

A University of Delaware marine scientist can confirm some of that ice loss firsthand. In a short video he produced, Andreas Muenchow, aboard the Canadian icebreaker Henry Larsen, shows the ice-free sea off Petermann Fjord that he and his colleagues were sailing in — an area that for ages had been covered by floating ice shelves.

New Report Reveals Food, Water Disparities along U.S.-Mexico Border

A UA study has found poverty, water scarcity, food insecurity and interdependence between the United States and Mexico along the border.

The U.S.-Mexico border is the border in the world with the greatest disparity in access to food and water needed for human survival, according to a report commissioned and published by the Southwest Center at the University of Arizona.

An endowment from the Kellogg Foundation and a UA Confluencenter for Creative Inquiry grant supported the study and its focus on assessing transborder food systems to understand water scarcity and food insecurity within the borderlands region.

The report underscores how in the globalized economy, Arizona and the rest of the United States rely on the skilled labor, water, fresh produce, fish, shellfish and livestock originating in northern Mexico; while in Mexico, the population is increasingly dependent upon frozen and processed foods originating in the United States.
