Study suggests life may have originated before Earth itself.
A new paper suggests that life on Earth could be 9.7 billion years old - more than 5 billion years older than Earth itself.
The authors argue that it may be possible to measure the rate at which the genetic complexity of life has increased on Earth, as measured by the number of non-redundant functional nucleotides in organisms. This growth has continued exponentially, in a similar way to Moores Law, allowing the team to work backwards to a date when just a single base pair indicates the start of life on Earth.
Let’s suppose for a minute that these guys are correct and ask about the implications of the idea. They say there is good evidence that bacterial spores can be rejuvenated after many millions of years, perhaps stored in ice.
Breakthrough could allow computer memory to get a 1000x speed boost.
A new paper published in the journal Nature shows a new way to switch magnetism at speeds at least 1,000 times faster than is currently used in magnetic memory technologies.
Time reversal technique could allow for some pretty crazy tech.
Researchers at the University of Maryland have demonstrated a method that allows power, sound, or images to be transmitted to an object without knowing exactly where it is, and without affecting objects around it.
One day the technology may be able to be used to direct microwaves to cancer cells to heat and destroy them, without affecting nearby tissue. It could also be used to transmit power to a smartphone, without even knowing where it is.
So how does it work?
New microchips are a “tool for secret agents”.
A new type of microchip developed at Caltech will allow devices such as smartphones or handheld scanners to easily scan and ‘see’ in inside objects using terahertz waves. The tiny chips (pictured above next to a penny) can be manufactured “Using the same low-cost, integrated-circuit technology that’s used to make the microchips found in our cell phones and notepads today”, according to the team.
Caltech describe the development like something from a spy novel, but the technology could soon feature in smartphones as well:
A secret agent is racing against time. He knows a bomb is nearby. He rounds a corner, spots a pile of suspicious boxes in the alleyway, and pulls out his cell phone. As he scans it over the packages, their contents appear onscreen. In the nick of time, his handy smartphone application reveals an explosive device, and the agent saves the day.
