Programmable DNA Scissors Found for Bacterial Immune System

Discovery Could Lead to Editing Tool for Genomes

Genetic engineers and genomics researchers should welcome the news from the Lawrence Berkeley National Laboratory (Berkeley Lab) where an international team of scientists has discovered a new and possibly more effective means of editing genomes. This discovery holds potentially big implications for advanced biofuels and therapeutic drugs, as genetically modified microorganisms, such as bacteria and fungi, are expected to play a key role in the green chemistry production of these and other valuable chemical products.

Despite Efforts for Change, Bangladeshi Women Prefer to Use Pollution-Causing Cookstoves

Women in rural Bangladesh prefer inexpensive, traditional stoves for cooking over modern ones — despite significant health risks, according to a Yale study in the Proceedings of the National Academy of Sciences.

A large majority of respondents (94%) believed that indoor smoke from the traditional stoves is harmful. Still, Bangladeshi women opted for traditional cookstove technology so they could afford basic needs.

“Non-traditional cookstoves might be more successful if they were designed with features valued more highly by users, such as reducing operating costs even if they might not reduce environmental impact,” said Mushfiq Mobarak, a co-author and associate professor of economics at the Yale School of Management.

Responsibility Misused by Politicians

The concept of responsibility is being used by politicians as a distraction from the real problems in society, which have to do with inequality according to research from the University of Exeter.

In the wake of the financial crisis there has been a renewed interest in issues of fairness and responsibility. The political debate about equality of opportunity, holding people responsible for their choices and helping people out when they suffer from undeserved bad luck has formed the focus of a four-year research project led by the University of Exeter.

Chromosome Painting: Discovering beauty in DNA

Everyone has a genetic story.

For artist Geraldine Ondrizek, an art professor at Portland’s Reed College, her story begins with the tragic loss of her child to a condition caused by a genetic anomaly. It’s a story that starts with her efforts to piece together her family’s genetic history and that has brought her, in the years since, to a beautiful intersection of science and art that today defines the very essence of her work.

Melting Sea Ice Threatens Emperor Penguins, Study Finds

At nearly four feet tall, the Emperor penguin is Antarctica’s largest sea bird—and thanks to films like “March of the Penguins” and “Happy Feet,” it’s also one of the continent’s most iconic. If global temperatures continue to rise, however, the Emperor penguins in Terre Adélie, in East Antarctica may eventually disappear, according to a new study by led by researchers from the Woods Hole Oceanographic Institution (WHOI). The study was published in the June 20th edition of the journal Global Change Biology.

“Over the last century, we have already observed the disappearance of the Dion Islets penguin colony, close to the West Antarctic Peninsula,” says Stephanie Jenouvrier, WHOI biologist and lead author of the new study. “In 1948 and the 1970s, scientists recorded more than 150 breeding pairs there. By 1999, the population was down to just 20 pairs, and in 2009, it had vanished entirely.” Like in Terre Adélie, Jenouvrier thinks the decline of those penguins might be connected to a simultaneous decline in Antarctic sea ice due to warming temperatures in the region.

Today in the Milky Way: Cloudy Skies

Adam Block of the UA’s Mount Lemmon SkyCenter brings us a rare view of the clouds wafting through our Milky Way in this Astronomy Picture of the Day.

In silhouette against the Milky Way’s faint starlight, its dusty molecular clouds likely contain raw material to form hundreds of thousands of stars, prompting astronomers to eagerly search the clouds for telltale signs of star birth.

This telescopic close-up looks toward the region at a fragmented Aquila dark cloud complex identified as LDN 673, stretching across a field of view slightly wider than the full moon.

For this image selected by NASA as the June 29 Astronomy Picture of the Day, astrophotographer Adam Block of the University of Arizona’s Mount Lemmon SkyCenter remotely operated the 32-inch Schulmann Telescope to peer into the vast chasms of gas and dust wafting through the Milky Way, exposing for about 15 minutes at a time during several nights in April and May.

Scientists Urge New Approaches to Plant Research

EAST LANSING, Mich. — You’d be amazed at how much you can learn from a plant.

In a paper published this week in the journal Science, a Michigan State University professor and a colleague discuss why if humans are to survive as a species, we must turn more to plants for any number of valuable lessons.

“Metabolism of plants provides humans with fiber, fuel, food and therapeutics,” said Robert Last, an MSU professor of biochemistry and molecular biology. “As the human population grows and nonrenewable energy sources diminish, we need to rely increasingly on plants and to increase the sustainability of agriculture.” (more…)
