#When Google got flu wrong When influenza hit early and hard in the United states this year,
A comparison with traditional surveillance data showed that Google Flu Trends, which estimates prevalence from flu-related Internet searches,
had overestimated drastically peak flu levels. The glitch is no more than a temporary setback for a promising strategy,
and Google is sure to refine its algorithms. But as flu-tracking techniques based on mining of web data
and on social media proliferate, the episode is a reminder that they will complement, but not substitute for, traditional epidemiological surveillance networks."
"It is hard to think today that one can provide disease surveillance without existing systems, says Alain-Jacques Valleron, an epidemiologist at the Pierre and Marie Curie University in Paris,
But the near-global coverage of the Internet and burgeoning social media platforms such as Twitter have raised hopes that these technologies could open the way to easier
The mother of these new systems is launched Google s in 2008. Based on research by Google and the CDC, it relies on data mining records of flu-related search terms entered in Google s search engine,
combined with computer modelling. Its estimates have matched almost exactly the CDC s own surveillance data over time
Google Flu Trends (www. google. org/flutrends; CDC; Flu Near Yougoogle Flu Trends has continued to perform remarkably well,
It is not the first time that a flu season has tripped Google up. In 2009, Flu Trends had to tweak its algorithms after its models badly underestimated ILI in the United states at the start of the H1n1 (swine flu) pandemic###a glitch attributed to changes in people s search behaviour as a result of the exceptional nature of the pandemic (S.

Presently, satellite internet relies on spacecraft that are travelling in geosynchronous orbit at the same speed as Earth rotates.

#Beating battery drain Stream video on your smartphone or use its GPS for an hour or two and you ll probably see the battery drain significantly.
As data rates climb and smartphones adopt more power-hungry features battery life has become a concern.
Now a technology developed by MIT spinout Eta Devices could help a phone s battery last perhaps twice as long
The primary culprit in smartphone battery drain is an inefficient power amplifier a component that is designed to push the radio signal out through the phones antennas.
Prepared to send sizeable chunks of data at any given time the amplifiers stay at maximum voltage eating away power more than any other smartphone component and about 75 percent of electricity consumption in base stations#and wasting
This means smartphone batteries lose longevity and base stations waste energy and lose money. But Eta Devices has developed a chip (for smartphones)
and a shoebox-size module (for base stations) based on nearly a decade of MIT research to essentially switch gears to adjust voltage supply to power amplifiers as needed cutting the waste.
When trialed in a base station last year Eta Devices module became the first transmitter for 4G LTE networks to achieve an average efficiency greater than 70 percent Dawson says.
Eta Devices has entered also conversations with major manufacturers of LTE-enabled smartphones to incorporate their chips by the end of next year.
Dawson says this could potentially double current smartphone battery life. Besides battery life Dawson adds there are many ways the telecommunications industry can take advantage of improved efficiency.
Eta Devices approach could lead to smaller handset batteries for example and even smaller handsets since there would be less dissipating heat.
