“This has been happening ever since I realized how often it feels as though I know something just because I can find it with Google. Technically, of course, I don’t know it. But when there’s a smartphone or… read more
The start of the Universe should be modeled not as a Big Bang but more like water freezing into ice, according to a team of theoretical physicists at the University of Melbourne and RMIT University.
They suggest that by investigating the cracks and crevices common to all crystals — including ice — our understanding of the nature of the Universe could be revolutionized.

The claim that “climate science is settled,” which runs through today’s popular and policy discussions, is misguided, says computational physicist Steven E. Koonin*, Director of the Center for Urban Science and Progress at New York University, writing in The Wall Street Journal Friday.
“It has … distorted our public and policy debates on issues related to energy, greenhouse-gas emissions and the environment … and inhibited… read more
Dr. Mark Post of Eindhoven University in the Netherlands hopes to produce meat in factories, The Economist reports.
He derives stem cells from cattle muscle,which are then multiplied a millionfold before they are put in Petri dishes and allowed to turn into muscle cells.
He plant to scale the process up by growing the cells on small spheres floating in tanks. Ultimately, he will use scaffolds made of… read more

NASA satellite data show the Earth’s atmosphere is allowing far more heat to be released into space than current computer models have predicted, according to a new study in the peer-reviewed science journal Remote Sensing.
Data from NASA’s Terra satellite shows that when the climate warms, Earth’s atmosphere is apparently more efficient at releasing energy to space than models used to forecast climate change have been programmed to… read more
Chinese astronauts may get fresh vegetables and oxygen supplies by gardening in extraterrestrial bases in the future, according to Deng Yibing, deputy director of the Beijing-based Chinese Astronaut Research and Training Center, Xinhua News reports.
Yibing said the experiment focused on a dynamic balanced mechanism of oxygen, carbon dioxide, and water between people and plants in a closed system.
According to Deng, a cabin of 300 cubic meters… read more
Scientists at Oxford University have developed a self-driving car that can cope with snow, rain and other weather conditions. The system can be fitted to existing cars and could one day cost just £100 (US$150), The Guardian reports.
The new system has been installed in a Nissan Leaf electric car and tested on private roads around the university. It will halt for pedestrians, and could take over… read more
For a decade, with support from the National Geographic Society, I’ve been organizing a study of the places where people live longest, Dan Buettner, author of The Blue Zones, writes in The New York Times.
The project grew out of studies by my partners, Dr. Gianni Pes of the University of Sassari in Italy and Dr. Michel Poulain, a Belgian demographer. In 2000, they identified a region of… read more
A new way to look at cancer — by tracing its deep evolutionary roots to the dawn of multicellularity more than a billion years ago — has been proposed by Paul Davies of Arizona State University’s Beyond Center for Fundamental Concepts in Science in collaboration with Charles Lineweaver of the Australian National University.
If their theory is correct, it promises to transform the approach to… read more
A revolutionary engine that can turn an aircraft into an orbiting spaceplane has won fresh backing from the British Government.
Until now, spacecraft heading for orbit have had to be launched by conventional rockets because of the amount of fuel needed to be get them… read more
As we noted previously, Kim Suozzi, 23, has terminal brain cancer that is highly aggressive and growing rapidly in a location that makes surgery impossible, and her final wish is to be cryopreserved.
“I learned about cryonics… read more
Einstein’s theory holds that nothing could move faster than the speed of light, but Professor Jim Hill and Dr Barry Cox in the University’s School of Mathematical Sciences have developed new formulas that allow for travel beyond this limit.… read more
