Scientists: Skin cells can behave like stem cells

USA Today

Scientists have made ordinary human skin cells take on the chameleon-like powers of embryonic stem cells, a startling breakthrough that might someday deliver the medical payoffs of embryo cloning without the controversy.

The new work is being published online by two journals, Cell and Science. The Cell paper is from a team led by Dr. Shinya Yamanaka of Kyoto University; the Science paper is from a team led by Junying Yu, working in the lab of in stem-cell pioneer James Thomson of the University of Wisconsin-Madison.

UW researcher reports stem cell breakthrough

Wisconsin State Journal

The UW-Madison researcher who grew the world’s first human embryonic stem cells has performed what he considers an even greater achievement: creating similar cells without using or destroying embryos.

James Thomson used a virus to deliver four select genes into human skin cells, which triggered the cells to revert to their embryonic state. The reprogrammed cells can then be coaxed into many of the body’s cell types, he said, helping scientists better learn the causes of diseases and possibly leading to cures.

Cabbage, kale: more than food (McClatchy-Tribune)

Quoted: You can eat these colorful cabbages and kales, but they might not be appealing. “Both ornamental cabbage and kale are edible, although they tend to be more bitter than the edible cultivars (and the pretty colors turn an unappetizing gray when cooked),” writes Susan Mahr, master gardener extension program coordinator at the University of Wisconsin-Madison, in an article for the program’s Web site.

Quoted: Michael S. Scott, who wrote “Robbery at Automated Teller Machines,” a guide for the Justice Department’s Office of Community Oriented Policing Services, believes ATM-related crime has gone down since he published his first research in 2001.

Scott, a professor at the University of Wisconsin-Madison Law School, is the former chief of police in Lauderhill.

Aim for safe deer hunt

Wisconsin State Journal

A UW-Madison study identified an oversized deer herd as a major cause for a decline in the diversity of the state ‘s flora and fauna. When deer too densely populate an area, they overbrowse on native plants, destroying habitat and food for birds, insects and other wildlife.

Fast Talk in the Emergency Department

Daily Cardinal

n the extreme sport called emergency medicine, the patient and physician in the emergency room are locked in a crucial relationship that requires clear and fast communication. In the most severe events, just how well the patient-physician interaction works within the chaotic hospital environment plays a major part in the quality of care delivered to patients.

Study pinpoints factors for early sex

USA Today

There’s a “recipe” that raises the odds of a teen starting sex early, and the more risky ingredients in a child’s life â?? for example, not feeling close to parents, low self-esteem and lots of TV â?? the more likely he is to be sexually active by age 15, suggests a study released over the weekend.

“It isn’t any one thing. It’s cumulative, and the more risks there are, the greater the chances that they’ll begin sex early,” says Janet Shibley Hyde, a psychologist at the University of Wisconsin-Madison. She and co-author Myeshia Price reported on their two-year study of 273 children at the Society for the Scientific Study of Sexuality meeting in Indianapolis.

Vet aims for cow comfort

Wisconsin State Journal

When veterinarian Ken Nordlund visits a dairy farm, he checks cows for more than disease.

He measures how much room they have when they eat. He scrutinizes their milking schedules for rest time. He watches them lie down and stand up in their stalls. He tracks how often they move from pen to pen.

Study finds hovering parents aren’t so bad (Marquette Tribune)

Quoted: Nancy Sandhu, the Parent Program coordinator at the University of Wisconsin-Madison, said in an e-mail that the vast majority of parents that contact her office want to help their child, but don’t know how to help. Parents call partly because they are making financial investments in their child’s education and want to see a return on their investment, she said.

Kid contemplatives: UW neuroscientist’s project aims to give middle-schoolers tools of ‘mindfulness’ and meditation

Capital Times

If gym class helps children tone the body, what helps them exercise the mind?

Homework and tests are logical answers, if proof of success is a higher GPA. But when the goal is to produce a more emotionally sturdy and thoughtful person, researchers suggest the ability to be still and contemplate is what can make a positive difference.

In 2008, local middle school students will among those who participate in a national pilot project that studies the effects of contemplation in the classroom, says Richard Davidson, a University of Wisconsin researcher/neuroscientist.

Winter Weather Preview (WTMJ-TV, Milwaukee)

What does mother nature have in store for us this winter? Weather Plus meteorologist John Malan combined science and folklore — to give us a look into the frigid future.

So how bad will it be? Global warming continues.

The NOAA temperature outlook predicts a warmer than normal winter. That trend worries climatologist Dr. Jon Martin.

“Ss each year goes by, I’m convinced that our lack of real cold mornings in particular has something to do with the global climate change,” the UW-Madison professor told us.
