<description><![CDATA[Following yesterday's revelation of a likely security breach at password management company LastPass, the company's CEO is revealing more details about the incident and trying to offer some comfort and advice to his users.Speaking yesterday with PC World, LastPass CEO Joe Siegrist admits he may have been too &quot;alarmist&quot; in sounding the alarm bell over the potential security breach. But the anomalies the company found when looking over its logs raised too much of a red flag.Siegrist explained that he doesn't think a lot of data would've been hacked, but just enough to capture a small number of user names and passwords. Though the passwords were in an encrypted format, those combined with the usernames could give hackers enough of a starting point to hunt for accounts with weak master passwords. The use of a master password is critical as it can unlock the door to all of a user's Web site passwords, one reason why sites like LastPass urge users to use complex, non-dictionary passwords.In fact, Siegrist asserted that users with a strong master password have no reason to worry at this point. It's people with weaker passwords who could be a bit more vulnerable. For such users, he's now advising them not only to replace their master password with a strong one, but also replace the individual passwords on certain critical accounts, such as e-mail and banking.Beyond those words of wisdom, Siegrist told PC World that the company is now forcing users to prove that they're coming from a known IP address or that they still have access to their e-mail. The CEO believes those extra steps should stop any hacker who may have guessed someone's master password. The company has also locked down certain services on the servers that were caught up in the incident and is investigating further to see if it finds any additional clues.LastPass is continuing to provide further updates on the situation through its ongoing blog.Security research firm Duo Security also offered its thoughts on the LastPass breach with some advice on what users can do at this point.<br/><br/>0 Vote(s) ]]></description>

<description><![CDATA[A Solar Junction wafer of high-efficiency solar cells. Each individual chip can produce about 20 watts.(Credit:Solar Junction)Solar Junction, a Silicon Valley solar start-up, said today that its solar cell has been measured at a peak efficiency of 43.5 percent, topping previous records.The San Jose, Calif.-based company said that the efficiency mark was verified by the National Renewable Energy Laboratory's Measurement and Characterization Laboratory. To achieve the 43.5 percent mark, Solar Junction designed a multijunction cell made of multiple layers of photovoltaic material. Each layer is optimized to convert a different portion of the light spectrum to electrical energy. To boost the amount of sunlight that goes into the very small, 5.5-millimeter square cells, light is concentrated with mirrors. The 43.5 percent efficiency was reached at a concentration of 400 suns and maintained that level up to 1,000 suns, Solar Junction said.Multijunction solar cells with concentrated sunlight have been used for decades in spacecraft and to make electricity in desert areas. Solar Junction intends to supply its cells to companies which manufacture concentrating solar photovoltaic (CPV) collectors, such as Amonix and Concentrix Solar, for utility-scale solar projects.The company expects that its multijunction cells, which are layered onto a gallium arsenide substrate, will continue to improve in efficiency, which will make CPV more attractive to utility-scale solar developers. Competing technologies are less efficient flat solar panels or concentrating solar thermal technology.  The 4-year-old company is seeking a Department of Energy loan guarantee to expand its production to 250 megawatts per year and to start shipping commercial cells within a year.<br/><br/>0 Vote(s) ]]></description>
