Emission reduction assumptions for carbon dioxide overly optimistic, study says

A new study published in Nature argues that the Intergovernmental Panel on Climate Change (IPCC) has underestimated the technological challenges of reducing CO2 emissions. The authors suggest that the IPCC's assumptions are overly optimistic, as spontaneous advances in technology will not carry most of the burden of achieving future em...

From Green Luddite to Techspressive: The ideology of consumer technology

Mathematicians find way to improve medical scans

Researchers at the University of Liverpool have developed a mathematical model that proves it is possible to gain full control of sound waves using meta-materials. This could lead to improved medical scans, such as ultrasound technology used in pregnancy tests, and quieter noisy machines by trapping sound.
