We're somewhat surprised when the Samsung-made Nexus is using a brand new chip architecture that many had thought would represent a fundamental leap in speed.
Some Web postings indicate it takes as much as 4 hours to charge the new iPad from a 31 percent to a 65 percent state of charge, which may reflect the impact of this fundamental physical limitation on recharge speed, despite how unhappy it makes users.
These chemicals may speed one of the most fundamental reactions in genetic research, called polymerase chain reaction (PCR), by allowing scientists to perform it at higher temperatures.
One challenge for all the new sequencing companies will be that Illumina and Life Technologies, the market leaders, have been able to increase the speed of their machines very quickly without fundamental changes in technology.
