Dramatic links found between climate change, elk, plants, and birds

without comments

Climate change in the form of reduced snowfall in mountains is causing powerful and cascading shifts in mountainous plant and bird communities through the increased ability of elk to stay at high elevations over winter and consume plants, according to a groundbreaking study in Nature Climate Change.

The U.S. Geological Survey and University of Montana study not only showed that the abundance of deciduous trees and their associated songbirds in mountainous Arizona have declined over the last 22 years as snowpack has declined, but it also experimentally demonstrated that declining snowfall indirectly affects plants and birds by enabling more winter browsing by elk. Increased winter browsing by elk results in trickle-down ecological effects such as lowering the quality of habitat for songbirds.

The Research Works Act: asking the public to pay twice for scientific knowledge

without comments

There’s been a lot of buzz in the science blogosphere recently about the Research Works Act, a piece of legislation that’s been introduced in the U.S. that may have big impacts on open access publishing of scientific results. John Dupuis has an excellent round-up of posts on the subject and Kevin Zeinio has a great rant on the topic of keeping scientific knowledge open and accessible, too. What follows is an analysis by Janet D. Stewwedel from the Scientific American blog. Read the rest of this entry »

Newly formed plants could lead to improved crop fertility

without comments

A new University of Florida study shows genomes of a recently formed plant species to be highly unstable, a phenomenon that may have far-reaching evolutionary consequences.

the study is the first to document chromosomal variation in natural populations of a recently formed plant species following whole genome doubling, or polyploidy. Because many agricultural crops are young polyploids, the data may be used to develop plants with higher fertility and yields. Polyploid crops include wheat, corn, coffee, apples, broccoli and some rice species.

“It could be occurring in other polyploids, but this sort of methodology just hasn’t been applied to many plant species,” said study co-author Pam Soltis, distinguished professor and curator of molecular systematics and evolutionary genetics at the Florida Museum of Natural History on the UF campus. “So it may be that lots of polyploids — including our crops — may not be perfect additive combinations of the two parents, but instead have more chromosomes from one parent or the other.”

Researchers analyzed about 70 Tragopogon miscellus plants, a species in the daisy family that originated in the northwestern U.S. about 80 years ago. The new species formed naturally when two plants introduced from Europe mated to produce a hybrid offspring, and hybridization was followed by polyploidy.

Evolutionary Biologist Lynne Margulis Dead at Age 72

without comments

This came in the form of an email from Bruno Clarke to the SLSA listserv. I’ve loved Margulis and Sagan’s books for years. In her youth, Margulis was married briefly to Carl Sagan, the father of her son, Dorion.

Lynn Margulis was Distinguished University Professor in the Department of Geosciences at the University of Massachusetts, Amherst. She was elected to the National Academy of Sciences in 1983, and in 1999 received the Presidential Medal of Science from Bill Clinton. Read the rest of this entry »

Home Printers that Make 3-D Objects

without comments

Just imagine: Instead of sending Grandma a holiday photo of the family for her fridge, you call up the image on your computer monitor, click “print,” and your printer produces a three-dimensional plastic model ready for hanging on the holiday tree. Scenes like that — in which homes have 3-D printers that build solid objects on demand – are fast approaching reality, according to the cover story in the current edition of Chemical & Engineering News, the American Chemical Society’s weekly newsmagazine.

In the article, C&EN Associate Editor Lauren K. Wolf explains that 3-D printers are on the verge of a personal revolution akin to the one that began in the 1970s and transformed computers from room-size machines to devices that fit on tables and now in pockets. A similar transformation is taking place in the world of 3-D printing, where machines are shrinking and the ability to create detailed objects from a variety of materials is growing. Engineers are now able to create objects out of a number of plastics, metals, ceramics and even foods like chocolate, sometimes with details as fine as a human hair.

The technology promises to foster revolutions in venues ranging from kitchens to hospital operating rooms. Some surgeons, for instance, envision printing bone grafts or replacement blood vessels with embedded proteins and cells that will help them fuse naturally. Chefs could print designer chocolates and gourmet meals with unique textures and tastes. “In 20 years, many people will have a 3-D printer in their kitchen for printing designer foods and other products,” the article quotes one scientist as saying.

Animal Production Practices Create Antibiotic Resistance

without comments

This report by Scientific American’s Steve Mirsky is interesting to me as I keep having to deal with people who insist that industrial-scale animal agriculture is “sustainable.” It may be economically sustainable for the animal ag industry, as long as Americans keeping stuffing themselves with beef, but it is not sustainable in terms of health costs — to humans and the environment.

“We produce nine billion food animals in the United States every year. And most of these animals are fed antibiotics throughout their life. And it’s the single greatest use of antibiotics in the United States.” Lance Price, director of the TGen North Center for Microbiomics and Human Health in Flagstaff, at the ScienceWriters2011 conference on October 16th.

“And then this is the thing that just drives public health people crazy: most antibiotics are fed to healthy animals to promote growth or to prevent diseases that may be just occurring because of the way we’re raising them. Overcrowding and unsanitary conditions—we call them production diseases. And so we’re using these lifesaving drugs as production tools. It’s pretty amazing.

“So most animals are raised in concentrated animal feeding operations, or CAPOs. I could not honestly engineer a better system for creating antibiotic-resistant bacteria than to introduce antibiotics to this setting. And that’s exactly what we do every day in the United States. If we all recognize that antibiotic resistance is one of the greatest threats to public health that we face today, we have to do something about this.”

What if population grows faster than the experts project? | 7 billion: What to expect when you’re expanding—a special series | Grist

without comments

Leading demographers, including those at the United Nations and the U.S. Census Bureau, are projecting that world population will peak at 9.5 billion to 10 billion later this century, and then gradually decline as poorer countries develop. But what if those projections are too optimistic? What if population continues to soar, as it has in recent decades, and the world becomes home to 12 billion or even 16 billion people by 2100, as a high-end U.N. estimate has projected? Such an outcome would clearly have enormous social and environmental implications, including placing enormous stress on the world’s food and water resources, spurring further loss of wildlands and biodiversity, and hastening the degradation of the natural systems that support life on Earth.

The real possibility of fertility decline stopping before the two-children level is reached requires demographers, policy makers, and environmentalists to seriously consider that population growth in the coming century will come in at the high end of demographic projections. The U.N.’s middle-of-the-road assumption for sub-Saharan Africa — that fertility rates will drop to three children per woman and population will reach 2 billion by 2050 — seem unrealistically low to me. More likely is the U.N.’s high-end projection that sub-Saharan Africa’s population will climb to 2.2 billion by 2050 and then continue to 4.8 billion by 2100. The dire consequences of such an increase are difficult to ponder. If sub-Saharan Africa is having trouble feeding and providing water to 880 million people today, what will the region be like in 90 years if the population increases fivefold — particularly if, as projected, temperatures rise by at least 3.6 degrees F, worsening droughts?

Why we crave creativity but reject creative ideas

without comments

Why did they reject my innovative idea?

Why did they reject my innovative idea?

This explains a lot!

Most people view creativity as an asset — until they come across a creative idea. That’s because creativity not only reveals new perspectives — it promotes a sense of uncertainty.

The next time your great idea at work elicits silence or eye rolls, you might just pity those co-workers. Fresh research indicates they don’t even know what a creative idea looks like and that creativity, hailed as a positive change agent, actually makes people squirm.

To uncover bias against creativity, the researchers used a subtle technique to measure unconscious bias — the kind to which people may not want to admit, such as racism. Results revealed that while people explicitly claimed to desire creative ideas, they actually associated creative ideas with negative words such as “vomit,” “poison” and “agony.”

Goncalo said this bias caused subjects to reject ideas for new products that were novel and high quality.

“Our findings imply a deep irony,” wrote the authors, who also include Jennifer Mueller of the University of Pennsylvania and Shimul Melwani of the University of North Carolina, Chapel Hill. “Revealing the existence and nature of a bias against creativity can help explain why people might reject creative ideas and stifle scientific advancements, even in the face of strong intentions to the contrary.”

Uncertainty drives the search for and generation of creative ideas, but “uncertainty also makes us less able to recognize creativity, perhaps when we need it most,” the researchers wrote. “Revealing the existence and nature of a bias against creativity can help explain why people might reject creative ideas and stifle scientific advancements, even in the face of strong intentions to the contrary. … The field of creativity may need to shift its current focus from identifying how to generate more creative ideas to identify how to help innovative institutions recognize and accept creativity.”

Beetle Queen Conquers Tokyo

with one comment

Beetle Queen Conquers Tokyo on DVD. The beetle may have conquered Japan, but the film conquers nothing.

Beetle Queen Conquers Tokyo
Grade: C-
reviewed by Brian Charles Clark
directed by Jessica Oreck

Beetle Queen Conquers Tokyo promises much more than it delivers. Directed by Jessica Oreck, a contributor to PBS’s Nature, the PR for the film alludes to science and a probing of the Japanese fascination with insects. Although Beetle Queen is a good-looking film with some interesting facets, it on the whole disappoints for its lack of narrative drive and its insistent but meandering obsession with tying together bits of Japanese poetry with shots of landscapes and bugs.

If we expected an in-depth look at Japanese culture and its people’s fascination with insects, I suppose we must be satisfied with the filmmaker’s visual anthropology. There are many arty shots in the film, that’s for sure, but they do not synergize into a narrative, nor do they create lyric intensity. With the emphasis on quoting snippets of Japanese literature, I suspect the latter, lyric mode was Oreck’s intention. I don’t think it works. The film is dry, full of lush (and creepy, no doubt, to the insectophobe) close-ups that ground us in nothing and leave us nowhere, offering nothing more than a macro shot of one bug after another.
