A better understanding of the Earth's climate requires a better understanding of the interaction between the planet's geophysical processes and the dynamics of the Solar System as a whole. So suggest University of Toronto physicist Jerry Mitrovica and Allessandro Forte of the Institut de Physique du Globe de Paris. The pair reached their conclusion based on numerical simulations that show a connection between Earth's changing shape and the gravitational effects of other bodies in the Solar System, particularly Jupiter and Saturn. "We're showing for the first time that changes in the Earth's shape, when coupled with the gravitational effects from other planets, can produce large changes in the Earth's climate," Mitrovica says, citing numerical simulations to show that these aspects of the Earth's orbit have been affected by the gravitational attraction of Saturn and Jupiter. His figures indicate that at some time during the last 20 million years, the Earth passed through a gravitational resonance associated with the orbits of Jupiter and Saturn, which in turn influenced the way the Earth's axial tilt changed during the same period. This gravitational pull would have had a much greater impact on the Earth millions of years ago when the Earth was shaped differently. For more information, contact Jerry Mitrovica at (416) 978-4946.
Enabling the Future is designing prosthetic appendages modeled more like superhero arms and hands than your average static artificial limbs. And they’re doing it through a website and grassroots movement inspired by two men’s design and creation in 2012 of a metal prosthetic for a child in South Africa.
In order to keep an enterprise truly safe from hackers, cyber security has to go all the way down to the device level. Icon Labs is making the point that security has to be built into device components.
Three days after NASA's MAVEN probe reached Mars, India's Mangalyaan probe went into orbit around the red planet. India's first interplanetary mission, and the first successful Mars probe launched by an Asian nation, has a total project cost of nearly $600 million less than MAVEN's.
Plant user interfaces are beginning to incorporate the consumer features such as swipe, double tap, and pinch. The driver is Millennials who expect plant equipment to match the sophistication of the smartphone.
