The CDF Collaboration blessed yesterday afternoon the results of a search for massive Gravitons decaying into pairs of Z bosons. And it is a startling new result!

Usually after a blessing (which is the result of a collaboration-wide presentation when the analysis is given a final scrutiny) the results are not immediately made public: this non-written rule has the purpose of allowing the analysis authors to be the first to present the results at a conference or other public event. But the rule written in the CDF bylaws, on the other hand, say that after a blessing the result is public, so for this time I will stick to the written one, and fair play be darned this time... The chances to announce what might be the first evidence of gravitons is too appealing!

A team of paleontologists said this week that some sauropod species went through drastic changes in skull shape during normal growth.

Researchers came to the conclusion after examining the The skull of a juvenile sauropod dinosaur, rediscovered in the collections of the Carnegie Museum of Natural History.

The fossil offers a rare chance to look at the early life history of Diplodocus, a 150 million-year-old sauropod from western North America.

The researchers believe these changes in skull shape may have been tied to feeding behavior, with adults and juveniles eating different foods to avoid competition. Young Diplodocus, with their narrower snouts, may also have been choosier browsers, selecting high quality plant parts.

Geologists have long thought that the rapid global cooling period nearly 13,000 years ago known as the Younger Dryas (Big Freeze) was triggered by the melting Laurentide ice sheet. But geological evidence for that theory has been lacking so far.

Now researchers writing in Nature say they have identified the mega-flood path across North America that channeled melt-water from the giant ice sheet into the oceans,  triggering the Younger Dryas cold snap.

Silicon is the basic material for most microprocessors and memory chips. But for a long time the electronics industry has been pursuing novel organic materials to create semiconductor products—materials that perhaps could not be packed as densely as state-of-the-art silicon chips, but that would require less power and cost less.

According to scientists at the National Institute of Standards and Technology (NIST), an organic semiconductor may be a viable candidate for creating large-area electronics, such as solar cells and displays that can be sprayed onto a surface as easily as paint.

However cute they may be, fat babies are likely to develop motor skills slower than their thinner counterparts, says a study just published in the Journal of Pediatrics.

The findings are based on observations of 217 African-American first-time mothers who participated in the Infant Care, Feeding and Risk of Obesity Study. The project is examining – in a population at risk of obesity – how parenting and infant feeding styles relate to infant diet and the risk of babies becoming overweight.
