Scientists who have developed a new way to create a type of radiation known as Terahertz (THz) or T-rays – the technology behind full-body security scanners – say their new, stronger and more efficient continuous wave T-rays could be used to make better medical scanning gadgets and may one day lead to innovations similar to the “tricorder” scanner used in Star Trek. The secret behind the innovation lies in the new nano-antenna that we had developed and integrated into the semiconductor chip. Arrays of these nano-antennas create much stronger THz fields that generate a power output that is 100 times higher than the power output of commonly used THz sources that have conventional interdigitated antenna structures.
Life is about to get a lot easier for medical researchers, but a lot more difficult for companies trying to make a buck selling them tools to store and analyze genomic data. When the Human Genome Project successfully concluded in 2003, it had taken 13 years to complete its goal of fully sequencing the human genome. Earlier this month, two firms — Life Technologies and Illumina– announced instruments that can do the same thing in a day, one for only $1,000. That’s likely going to mean a lot of data.
Obsessive gamers hours at the computer have now topped scientists efforts to improve a model enzyme, in what researchers say is the first crowdsourced redesign of a protein.The online game Foldit, developed by teams led by Zoran Popovic, director of the Center for Game Science, and biochemist David Baker, both at the University of Washington in Seattle, allows players to fiddle at folding proteins on their home computers in search of the best-scoring lowest-energy configurations.
Esqueça o Facebook e o Twitter. Micah Sifry, do conceituado TechPresident, é taxativo – neste ano as eleições americanas serão sobre Big Data.
So what happened with the Internet in 2011? How many email accounts were there in the world in 2011? How many websites? How much did the most expensive domain name cost? How many photos were hosted on Facebook? How many videos were viewed to YouTube?We’ve got answers to these questions and many more. A veritable smorgasbord of numbers, statistics and data lies in front of you. Using a variety of sources we’ve compiled what we think are some of the more interesting numbers that describe the Internet in 2011.
