Thrilling discovery of seven Earth-sized planets orbiting nearby star

Secen earth siaze planets discoveredA huddle of seven worlds, all close in size to Earth, and perhaps warm enough for water and the life it can sustain, has been spotted around a small, faint star in the constellation of Aquarius.

The discovery, which has thrilled astronomers, has raised hopes that the hunt for alien life beyond the solar system can start much sooner than previously thought, with the next generation of telescopes that are due to switch on in the next decade.

Human effects on Earth are 170 times greater than natural forces: Study

Human effects on earthScientists at the Australian National University have come up with a simple equation to calculate the impact of human forces on planet Earth. The numbers suggests humans are accelerating climate change by a factor 170 times greater than natural forces.

"Over the past 7,000 years the primary forces driving change have been astronomical -- changes in solar intensity and subtle changes in orbital parameters, along with a few volcanoes, " Will Steffen, a professor at ANU's Climate Change Institute, explained in a news release. "They have driven a rate of change of 0.01 degrees Celsius per century."

First human-pig embryos created by scientists

Human-pig embryo Scientists have for the first time grown embryos that contain a combination of pig and human stem cells, in a step towards one day growing transplantable organs, a study says.

However, the research remains at a very early stage and proved more difficult than expected, the researchers reported in the peer-reviewed journal Cell on Thursday.

"This is an important first step," said lead investigator Juan Carlos Izpisua Belmonte, a professor in the Salk Institute of Biological Studies' Gene Expression Laboratory.
