More Than Half of Americans Aren’t Confident in the Big Bang Theory
While scientists believe the universe began with a big bang, most Americans put a big question mark on the concept, an Associated Press-GfK poll found. Yet when it comes to smoking causing cancer or that a genetic code determines who we are, the doubts disappear. When considering concepts scientists consider truths, Americans have more skepticism than confidence in those that are farther away from our bodies in scope and time: global warming, the age of the Earth and evolution and especially the big bang from 13.8 billion years ago.

Can Feeling Pleasure From Meaningful Activities Protect Teens From Developing Depression?
In a new study, researchers aimed to figure out how the tender brains of adolescents reacted to the more bacchanalian rewards, like video games and drugs, versus the more prosocial ones, like “helping others in need, expressing gratitude, and working toward long-term goals.” Would the teens who get their jollies from volunteering be happier, in the long run, than those who live only for Grand Theft Auto?

Why Were All of the Artifacts at a 4,500-Year-Old Site in California Removed and Reburied?
The story is actually a lot more complicated than Good Archaeologists vs. Bad Developers. The actual decision to rebury the artifacts wasn’t left to the town or to the developers. The call was made by the Federated Indians of Graton Rancheria, the likely descendants of the ancient people who lived on the site. (Mary Beth Griggs, Smithsonian.com)
The Faith-Based Environmentalism of “Noah”
Chris Mooney: No matter what the Christian right may say, Noah is a deeply religious and spiritual film containing an authentic moral message. And that message feeds strongly into a vital and growing religious tradition of our time, one that especially appeals to younger believers: faith-based environmentalism, or what is sometimes called “creation care,” which uses biblically based moral imperatives to impel conservation and stewardship.

The Conversation organized a public question-and-answer session on Reddit in which Jeremy Pritchard, senior lecturer in biology at the University of Birmingham, explained the science of evolution and tackled the contentious issue of science and religion. Here are curated highlights. (The Conversation)

Gregg Caruso sent us a note about this newly published collection of interviews—based on five questions—with 33 leading philosophers, scientists, theologians, apologists, and atheists. (Regular readers of this blog will recognize many of the names.) The work is edited by Caruso, the editor of the recently launched journal Science, Religion and Culture.
Steven Pinker has blurbed the book, as has theologian Philip Clayton, who writes:
Imagine that some of the world’s best-known scientists, philosophers, and religionists were to offer up their answers to an identical set of probing questions. Imagine that these articulate statements, composed by scholars who think deeply about science and religion, are then assembled in a single collection. That’s the volume you’re holding—a fascinating snapshot of where the dialogue stands today, and of what it has (and hasn’t yet) achieved.

Screening Digital Embryos
A service that creates digital embryos by virtually mixing two people’s DNA will give a clearer glimpse of their possible child’s health, and perhaps much more—before it has been conceived. The Matchright technology will be available in two U.S. fertility clinics later this month, allowing people to screen out sperm donors who, when their genes are combined with those of the intended mother, could increase the risk of a child inheriting genetic diseases. The company that markets the technology, GenePeeks, hopes to expand worldwide. But the technology’s patent also includes a list of traits that aren’t necessarily related to health.

Julian Savulescu: Researchers at Cardiff University discovered that children with two copies of a common gene (Thr92Ala), together with low levels of thyroid hormone, are four times more likely to have a low IQ. This combination occurs in about 4 percent of the U.K. population. Importantly, if you had just one of these factors, but not both, there did not appear to be an increased risk of low intelligence. These are early results, but suggest that it might be possible to treat children early with thyroid hormone supplementation to enhance their intelligence. This raises many ethical issues.

Scientists Regenerate an Organ in Mice
The team manipulated a single protein in very old mice that caused their bodies to rebuild their thymuses—an organ that produces white blood cells. After receiving the treatment, the senior citizen mice not only had thymuses that were similar in structure to a young whippersnapper’s, but they were also twice as large. Scientists have in the past grown organs using stem cells, but this is the first time a living organism has repaired its own organs via a chemical trigger. (Carl Engelking, D-brief, Discover)
No matter how much of a critical thinker you consider yourself, your brain is pretty gullible. With a few minutes and a couple of props, your brain can be convinced that one of your limbs is made of rubber or invisible, or that your whole body is the size of a Barbie doll’s. All these illusions depend on your senses of vision and touch interacting. But a new illusion trades sight for sound. By hearing the sound of a hammer striking marble each time it tapped their hands, subjects came to feel that their limbs were made of stone. (Elizabeth Preston, Inkfish, Discover)
Are the Australopithecus Sediba Fossils Actually the Remains of Two Species?
The first fossils of A. sediba were found at Malapa, South Africa, in 2008. At 2 million years old, they show a mix of features, some similar to the ape-like australopithecines, others more like our genus, Homo. To its discoverers, this hotchpotch means A. sediba was becoming human, and that the Homo genus first evolved in South Africa, not east Africa as is generally thought. But a new analysis suggests A. sediba didn’t exist. “I think there are two different hominin genera represented at Malapa,” says Ella Been at Tel Aviv University in Israel.

A History of Religion in 5 1/2 Objects
Jenna Weissman Joselit: Taking the measure of stone, incense, drums, crosses, and bread, S. Brent Plate’s book is an extended exercise in the materiality of faith. You might even call it a manifesto. Blurring the lines between inquiry and advocacy, it doesn’t just ask us to consider the multiple ways in which religion is a tactile phenomenon. It also calls on us to affirm and perhaps even to celebrate the sensory elements of faith. “The religious point is to pay attention, to feel, now,” he writes. (New Republic)
