EARTH: Famous fossils and spectacular scenery at British Columbia's Burgess Shale

2013-01-03
(Press-News.org) Alexandria, VA – The Burgess Shale provides us with a rare glimpse into the softer side of paleontology. Most fossils are preserved hard parts – bones, teeth and shells – but one of the most famous fossil locales in the world, the Burgess Shale, reveals subtle soft body structures like gills and eyes delicately preserved between the layers of dark rock. For more than 100 years, the Burgess Shale has been giving us a unique perspective on what life was like in the Cambrian seas. This month, EARTH Magazine contributor Mary Caperton Morton reminds us that no matter how well we think we know a fossil locality, it can still surprise us.

Since its discovery, more than 100,000 fossils have been removed from the site – the vast majority stored in drawers at the Smithsonian and the Royal Ontario Museum – and yet visitors regularly find treasure after overturning just a few slabs. Removing fossils is prohibited, however, and a number of motion- and pressure-sensor cameras protect the UNESCO World Heritage Site from unescorted visitors and sticky-fingered fossil enthusiasts, ensuring that the Burgess Shale will be able to dazzle us for years to come.

Physician review websites rely on few patient reviews

2013-01-03
MAYWOOD, Il. - Millions of Americans read physician ratings on websites such as Healthgrades.com, but such ratings are based on scores from an average of only 2.4 patients, a Loyola University Medical Center study has found. The study of 500 randomly selected urologists found that 79.6 percent of physicians were rated by at least one of the 10 free physician-review websites researchers examined. Eighty-six percent of physicians had positive ratings, with 36 percent receiving highly positive ratings. Healthgrades had the most physician ratings. Results were published ...

Let crying babes lie: Study supports notion of leaving infants to cry themselves back to sleep

2013-01-03
Today, mothers of newborns find themselves confronting a common dilemma: Should they let their babies "cry it out" when they wake up at night? Or should they rush to comfort their crying little one? In fact, waking up in the middle of the night is the most common concern that parents of infants report to pediatricians. Now, a new study from Temple psychology professor Marsha Weinraub gives parents some scientific facts to help with that decision. The study, published in Developmental Psychology, supports the idea that a majority of infants are best left to self-soothe ...

New UGA research helps explain why girls do better in school

New UGA research helps explain why girls do better in school
2013-01-03
Athens, Ga. – Why do girls get better grades in elementary school than boys—even when they perform worse on standardized tests? New research from the University of Georgia and Columbia University published in the current issue of Journal of Human Resources suggests that it's because of their classroom behavior, which may lead teachers to assign girls higher grades than their male counterparts. "The skill that matters the most in regards to how teachers graded their students is what we refer to as 'approaches toward learning,'" said Christopher Cornwell, head of economics ...

Researchers demonstrate record-setting p-type transistor

2013-01-03
CAMBRIDGE, MA -- Almost all computer chips use two types of transistors: one called p-type, for positive, and one called n-type, for negative. Improving the performance of the chip as a whole requires parallel improvements in both types. At the IEEE's International Electron Devices Meeting (IEDM) in December, researchers from MIT's Microsystems Technology Laboratories (MTL) presented a p-type transistor with the highest "carrier mobility" yet measured. By that standard, the device is twice as fast as previous experimental p-type transistors and almost four times as fast ...

NASA sees a struggling post-Tropical Storm Freda affecting New Caledonia

NASA sees a struggling post-Tropical Storm Freda affecting New Caledonia
2013-01-03
Tropical Storm Freda may no longer be a tropical storm, but as a low pressure area it is bringing rainfall and gusty winds to New Caledonia. Two NASA satellites captured two different looks at the storm. Wind shear has punched Freda down to tropical storm status on Jan. 1 and weakened it to a remnant low pressure area on Jan. 2. NASA's Aqua satellite showed strong thunderstorms were over New Caledonia early on Jan. 2, while NASA's Tropical Rainfall Measuring Mission (TRMM) satellite peered under the hood of Freda's clouds and measured some moderate to heavy rainfall the ...

For those short on time, aerobic, not resistance, exercise is best bet for weight, fat loss

2013-01-03
BETHESDA, Md. (Jan. 2, 2012)—A new study led by North Carolina researchers has found that when it comes to weight- and fat loss, aerobic training is better than resistance training. The study is believed to the largest randomized trial to directly compare changes in body composition induced by comparable amounts of time spent doing aerobic and resistant training, or both in combination, among previously inactive overweight or obese non-diabetic adults. The study is entitled "Effects of aerobic and/or resistance training on body mass and fat mass in overweight or obese ...

Study: Generational changes cause drop in US support for school prayer

2013-01-03
There's a saying that goes, "as long as there are tests, there will be prayer in public schools." At one time, that likely reflected a fairly uniform view about school prayer: that despite what federal law said about the practice, religious Americans by and large approved of it. A new study, however, paints a more complicated picture of attitudes toward school prayer over the last four decades, finding sharp differences in school-prayer support between different generations and their religious denominations. Forthcoming in the journal Sociological Forum, the study ...

Identifying the molecular causes of vision loss in demyelinating disease

2013-01-02
Demyelinating diseases, such as multiple sclerosis (MS), are frequently associated with the progressive loss of vision. The retinal nerve damage is thought to be caused by immune system-mediated inflammation; however, other demyelinating disorders, such as Pelizaeus-Merzbacher disease, do not involve the immune system, suggesting that there are other causes of retinal nerve damage. Deimination is a protein modification that is altered in patients with MS and PMD. In this issue of the Journal of Clinical Investigation, researchers led by Sanjoy Bhattacharya at the University ...

Bacterial imbalance contributes to intestinal inflammation and carcinogenesis Instability in the composition of gut bacterial communities (dysbiosis) has been linked to common human intestinal disorders, including inflammatory bowel disease and colorectal cancer; however, it is unclear if dysbiosis can instigate disease or if it is a consequence of the underlying disorder. In this issue of the Journal of Clinical Investigation, researchers led by Mathias Chamaillard at the University Lille Nord de France in Lille, France, examined intestinal inflammation and tumorigenesis ...
