“ ‘Nones’ On the Rise,” released by the Pew Forum on Religion & Public Life in affiliation with PBS’ Religion & Ethics NewsWeekly, gives the sense that we can see what’s really going on across the American religious landscape and understand it. The following data points from the report, for instance, seem to make clear…
Rapid urbanization will take a heavy toll on public health if city planning and development do not incorporate measures to tackle air pollution, warns a new study. The report, compiled by the World Meteorological Organization (WMO) and the International Global Atmospheric Chemistry (IGAC), was launched in Beijing in September as part of the IGAC Open…
A 520-million-year-old, three-inch fossil has yielded evidence that complex brains evolved much earlier than previously thought. The preserved external skeleton of Fuxianhuia protensa, an extinct type of arthropod, is the earliest known fossil to show a complex brain, according to a study published in the journal Nature. “No one expected such an advanced brain would…
In a laboratory in Scotland, a revolutionary kind of laser is taking shape – the first one to be made out of an artificial black hole. Once complete, the device could help confirm mounting evidence that real black holes, despite their name, emit light. A black-hole laser could also find practical uses in devices that…
It’s been 3 years since the legality of federal funding for research involving human embryonic stem cells (hESC) was first brought to the US court system, and despite some tense moments, including a temporary ban on National Institutes of Health (NIH) funding for hESC research, the courts have continued to uphold the legality of such…
Jim Yong Kim, the new president of the World Bank, said that dealing with climate change will be one of his priorities. “Since becoming president of the World Bank, I have looked deeply into the data on climate change, and I have to say I was surprised that even in last 6 months to a…
Reducing the risk of extinction for threatened species and establishing protected areas for nature will cost the world over $76 billion annually. Researchers say it is needed to meet globally agreed conservation targets by 2020. The scientists say the daunting number is just a fifth of what the world spends on soft drinks annually. And…
A New York Medical College developmental biologist whose life’s work has supported the theory of evolution has developed a concept that dramatically alters one of its basic assumptions—that survival is based on a change’s functional advantage if it is to persist. Stuart A. Newman, Ph.D., professor of cell biology and anatomy, offers an alternative model…
A meteorite that fell in Morocco last year might contain the freshest evidence for water on Mars, according to a study published in Science. The meteorite, named Tissint after the town nearest its landing site, was identified as a Mars rock in January. Now, Hasnaa Chennaoui Aoudjehane and her colleagues report that Tissint contains evidence…
Palaeogeneticists have examined 158 DNA-containing leg bones belonging to three species of extinct giant birds called moa. The bones, which were between 600 and 8,000 years old, had been recovered from three sites within 5 kilometres of each other. By comparing the specimens’ ages and degrees of DNA degradation, the researchers calculated that DNA has…
