Spanking Found To Have Negative Effects On Low-income Toddlers

ScienceDaily (Sep. 15, 2009) — A new longitudinal study that looks at how low-income parents discipline their young children has found that spanking 1-year-olds leads to more aggressive behaviors and less sophisticated cognitive development in the next two years. Verbal punishment is not associated with such effects, especially when it is accompanied by emotional support from moms. In addition, 1-year-olds' fussiness predicted spanking and verbal punishment at ages 1, 2, and 3.

The study, which explored whether mothers' behaviors lead to problematic behavior in children, whether children's challenging behaviors elicit harsher discipline, or both, appears in the September/October 2009 issue of the journal Child Development. It was conducted by researchers at Duke University, the University of Missouri-Columbia, the University of South Carolina, Columbia University, Harvard University, and the University of North Carolina at Chapel Hill.

You mean there's a comet with donuts? Or maybe beer?

Comet Contains One of Life’s Precursors (Wired Science))

Scientists have discovered the amino acid glycine, a critical component of all living things, hiding in samples from the comet Wild 2.

It’s the first time an amino acid has been found inside a comet, and NASA scientists say the discovery supports the theory that some of the ingredients necessary for life originated in space and traveled to Earth by comet or meteorite.

“If you’re seeing amino acids in comets, then that really gives credence to the idea that the basic componenets of life are going to be widespread throughout the universe,” said planetary biologist Max Bernstein of the NASA Astrobiology Institute, who was not involved in the research. “It’s one thing for me to do it in the lab and say it should be so, but it’s another thing for somebody to actually measure it.”

Glycine was isolated from tiny samples of material collected from Wild 2 in 2004 by the NASA spacecraft Stardust. As the spacecraft flew through dense clouds of gas and dust surrounding the comet’s nucleus, a container of aerogel trapped particles from the comet. Since the aerogel capsule was parachuted to Earth in 2006, scientists have been racing to analyze the contents of the collected samples. Although preliminary reports indicated traces of glycine in the aerogel, researchers didn’t have enough aerogel sample to determine whether the amino acid was an Earthly contaminant or had truly come from space.

To get enough glycine for their analysis, the scientists actually analyzed the aluminum foil that lined the inside of the aerogel collection grid. Volatile gas particles had diffused through the aerogel and gotten stuck to the foil — but even the foil provided only a half a nanamole of glycine to work with, and it took the researchers two years to confirm that the glycine had extraterrestrial origins.

“What we did was look at the carbon isotopes,” said NASA scientist Jamie Elsila, who presented the work Sunday at the American Chemical Society meeting in Washington D.C. “The stuff on the Earth has a special signature, and the extraterrestrial signature is very different. When we looked at glycine and measured its carbon signature, we saw that it’s in the extraterrestrial range.”

Yeah, you try to explain causality to a headline writer. Go on, try it.

Blue M&Ms linked to reducing spine injury

(CNN) -- The same blue food dye found in M&Ms and Gatorade could be used to reduce damage caused by spine injuries, offering a better chance of recovery, according to new research.

Researchers at the University of Rochester Medical Center found that when they injected the compound Brilliant Blue G (BBG) into rats suffering spinal cord injuries, the rodents were able to walk again, albeit with a limp.

The only side effect was that the treated mice temporarily turned blue.

So, we guess that what we always heard about the green ones was true

Prehistoric Bears Ate Everything And Anything, Just Like Modern Cousins

ScienceDaily (Apr. 13, 2009) — By comparing the craniodental morphology of modern bear species to that of two extinct species, researchers from the University of Málaga have discovered that the expired plantigrades were not so different from their current counterparts. The cave bear, regarded as the great herbivore of the carnivores, was actually more omnivorous than first thought.

The short-faced bear, a hypercarnivore, also ate plants depending on their availability. The work offers key insights into the evolution of the carnivore niches during the Ice Age.

The team of palaeontologists have reconstructed the trophic ecology, or eating habits, of two extinct bear species that lived during the Pleistocene (between 2.59 million and 12,000 years ago): the short-faced bear (Arctodus simus) of North America and the cave bear (Ursus spelaeus) of Europe. The morphometric analysis carried out on the eight bear species in existence today has confirmed that prehistoric bears were not fussy eaters.

'Knowing what the extinct bears ate is of utmost relevance to finding out about the evolution of carnivore niches in the Pleistocene when climatic conditions were changing', explains Borja Figueirido, lead author of the study and researcher for the Ecology and Geology Department of the Faculty of Sciences at the University of Málaga. Scientists have discovered that, even at that time, bears were 'great opportunists' thanks to their morphological and ecological flexibility.

Trophic ecology and morphological flexibility. Yeah Dude, break me off some of that.

Robot achieves scientific first

A laboratory robot called Adam has been hailed as the first machine in history to have discovered new scientific knowledge independently of its human creators.

Adam formed a hypothesis on the genetics of bakers’ yeast and carried out experiments to test its predictions, without intervention from its makers at Aberystwyth University.

The result was a series of “simple but useful” discoveries, confirmed by human scientists, about the gene coding for yeast enzymes. The research is published in the journal Science.

Professor Ross King, the chief creator of Adam, said robots would not supplant human researchers but make their work more productive and interesting.

“Ultimately we hope to have teams of human and robot scientists working together in laboratories,” he said.

Adam is the result of a five-year collaboration between computer scientists and biologists at Aberystwyth and Cambridge universities.

The researchers endowed Adam with a huge database of yeast biology, automated hardware to carry out experiments, supplies of yeast cells and lab chemicals, and powerful artificial intelligence software.

Interesting. A robot achieves limited consciousness and the first thing it does is try to figure out how to make beer.
