Are cell phones safe? Researchers still uncertain
September 14th, 2009 | 
Author: WASHINGTON, D.C.–The question over whether cell phones pose a health risk has been debated for years, and researchers say the final answer could still be years away.
Since the wireless industry’s early days, there have been fears that cell phones could be harmful to your health. Some 600 studies have been conducted on the health effects of cell phone use, but the results have been conflicting.
Several reputable organizations, including the World Health Organization and the National Cancer Institute, say there’s no conclusive evidence that using cell phones can harm your health. Other independent research, meanwhile, indicates a link between health problems and cell phone use.
The Interphone study, which began over a decade ago involving 13 countries and has been funded in part by the wireless industry, was supposed to settle the dispute. But the report’s publication has been delayed as researchers disagree over how to interpret the data. Some countries have ended up publishing some results on their own. Much of it indicates there is a link between brain tumors and cell phone use of 10 years or more.

Solar start-up squeezes more juice from silicon cells
1366 Technologies, a spinoff from the Massachusetts Institute of Technology, says it can produce a very efficient solar cell from silicon which will be in the market in two years.
The Lexington, Mass.-based company on Monday plans to disclose the details of its Self-Aligned Cell (SAC) architecture, a set of technologies it has developed to convert 18 percent of sunlight to electricity with polysilicon, the most common solar cell material. Engineers forecast that they will be able to hit 19 percent efficiency in the next nine months without adding significant cost to existing processes, said Ely Sachs, chief technology officer.

New school year brings ‘Green IT’ college degree
Making data centers more energy efficient has been elevated to a college degree.
IBM on Wednesday said it has developed a two-year associates degree in “green data center management” in collaboration with the Metropolitan Community College in Omaha, Neb.
Existing technologies like virtualization can improve data center efficiently significantly. Emerging technologies such as this wireless sensor promise better control over equipment and facilities.

Starting in December, students will learn how to design and manage data centers to run efficiently in what IBM says is the first college degree in the subject. Classes will be offered online to remote students as well.
The Environmental Protection Agency in 2007 estimated that data centers alone use about 1.5 percent of all electricity in the U.S. and are on a pace to double consumption in the coming years. With existing technologies, energy use could be cut by 25 percent, representing up to $4 billion in savings, the EPA found.
Because of financial and environmental concerns, more data center operators are taking steps to cut energy use, such as consolidating server workloads and upgrading cooling systems. Companies such as IBM, HP, and IT consulting companies have practices in designing facilities to be more efficient.
The green IT degree from IBM and Metropolitan Community College covers technologies for consolidating computing work loads, including virtualization, as well as security and disaster recovery. The course work also addresses the nuts and bolts of building and managing a facility, such as cabling and monitoring.
The data center where the class will be taught, which will be stocked with IBM servers, was funded by a $1.8 million Department of Labor grant.

Major earthquake strikes Indonesia, kills 6
JAKARTA, Indonesia — Six people were killed in Indonesia after a 7.0-magnitude earthquake struck Wednesday, officials said.
The quake was initially categorized as magnitude 7.4 before being downgraded to 7.0 by geological officials.
No details were immediately available about the deaths. At least 18 other people were injured around the capital, Jakarta, said Rustam Pakaya, a health ministry spokesman.
A tsunami watch went into effect and quickly expired, according to the Pacific Tsunami Warning Center.
It struck about 2:55 p.m. (3:55 a.m. ET) and was centered 242 km (150 miles) from Jakarta, according the U.S. Geological Survey. The quake was about 60 km (37.3 miles) deep.
In Tasikmalaya, a city in the Indonesian island of Java, some older buildings were damaged and people panicked in the streets because there was no electricity, according to a witness named Maya.
Tasikmalaya is about 142 km (88 miles) from the epicenter. Several homes in that city were destroyed and a building collapsed, the health ministry spokesman said.
John Aglionby, a journalist with the Financial Times, was in Jakarta during the quake.
“The whole building started to sway. People got very serious,” Aglionby told CNN. “People left the building. But there was no sign of damage here.”
About three weeks ago, a series of earthquakes — ranging in magnitude from 4.7 to 6.7 — struck off the western coast of Indonesia’s Sumatra Island.
At least seven people were injured and one building collapsed in Padang City in West Sumatra, officials said.
– CNN’s Andy Saputra contributed to this report.

LA fire likely to pass across Mount Wilson
The wildfire ravaging Northern Los Angeles County is expected to pass across Mount Wilson, home to TV and radio towers and the famed Wilson Observatory.
Mount Wilson Observatory Director Hal McAlister said Monday in an ongoing blog that the U.S. Forest Service informed him that passage of the fire across Mount Wilson was imminent. The USFS also said firefighters would battle the blaze from the air rather than on the ground.
Firefighers have already been pulled from Red Box, a major staging area about five miles from the observatory.
In his blog late Monday, McAlister reported:
Monday, 31 Aug 09, 2:46 pm PDT – I just spoke with Sherry Roman, Public Affairs Officer of the Angeles National Forest. She could give no updates as to the status of the fire in the Mount Wilson vicinity except that the USFS still considers that passage of fire across Mount Wilson is imminent and will be fought aerially rather than with ground personnel. Once the fire is through the area, they can assess the damage by air after the event before they can send in ground personnel. She also confirmed that firefighters have been removed from Red Box.This roller coaster has taken a dip downward.
McAlister’s latest blog (which mistakenly lists the day as Monday rather than Tuesday):
Monday, 1 Sep 09, 7:15 am PDT – …I do not at this point have any news – only what we can all deduce from Towercam and other sources. Towercam scenes continue to show thick smoke on the mountain with a concentration on the right side of the image implying activity on the mountain’s north side. It clearly has not reached the mountain and, if advancing towards us, it is only doing so slowly.
McAlister also reported that one of the two power lines to the mountain was knocked out by the fire. But the towercam showing the latest images is still online for now, allowing the Mount Wilson staff to monitor the flames.
The latest news from CBS in Los Angeles reports that the Station fire is still only 5 percent contained, and officials don’t expect full containment for another two weeks. At this point, the fire has destroyed 121,000 acres and 53 homes.
