European satellite to test method to find ripples in space, time
From a vantage point 93 million miles (1.5 million km) from Earth, the European-built spacecraft, known as LISA Pathfinder, is expected to break ground in the search for the ripples, known as gravitational waves, caused by fast-moving, massive celestial objects such as merging black holes. Black holes are so dense with matter that not even photons of light can escape the powerful gravitational effects. God knows what we will learn," said European Space Agency deputy mission scientist Oliver Jennrich.

New from the biotech store: an improved gene editing tool
Scientists have developed an improved gene editing tool that significantly reduces potentially dangerous "off-target" edits, promising an even more precise and efficient system for manipulating human DNA. Tuesday's news that U.S. researchers have re-engineered the so-called CRISPR-Cas9 system to slash editing errors comes as experts meet in Washington for a three-day summit to discuss the ethical and policy issues surrounding the field.

China plans to launch carbon-tracking satellites into space
China plans to launch satellites to monitor its greenhouse gas emissions as the country, estimated to be the world's top carbon emitter, steps up its efforts to cut such emissions, official news agency Xinhua said on Monday. News of the plan comes as more than 150 world leaders arrived in Paris for climate change talks and Chinese President Xi Jinping and U.S. President Barack Obama said they would work together towards striking a deal that moves towards a low-carbon global economy. According to the Xinhau report, the country's first two carbon-monitoring satellites will be ready by next May after four years of development led by Changchun Institute of Optics and Fine Mechanics and Physics, part of China's Academy of Sciences.

Satellite launch to test Einstein's idea on space and time delayed
A European satellite launch to find ripples in space that can be caused by merging black holes has been delayed due to a technical problem with its Vega rocket, the European Space Agency (ESA) said on Tuesday. The European-built spacecraft, known as LISA Pathfinder, was due to be launched from French Guiana at 0415 GMT on Wednesday. Such delays due to technical issues or poor weather are not unusual.

Hypersonic rocket engine could revolutionize space flight
By Matthew Stock Oxfordshire-based Reaction Engines are developing a new aerospace engine class that combines both jet and rocket technologies. The company recently announced a strategic investment from BAE Systems of 20.6 million pounds ($31.4 million USD), in addition to a grant funding of 60 million pounds ($.4 million USD) from the British government, to accelerate the development of their unique SABRE engine. SABRE, which stands for Synergetic Air-Breathing Rocket Engine, is designed to enable aircraft to operate from a standstill on the runway to hypersonic flight in the atmosphere, and then transition to rocket mode for spaceflight.
