Cellphones are not linked to cancer, a recent study found.The latest study on cellphones and cancer has found no increased risk - in line with a number of earlier studies.
The scope of the Danish study, published in Friday's British Medical Journal, is impressive but unlikely to end debate on whether cellphones are bad for the health.
Researchers followed more than 350,000 people who had a cellphone between 1987 and 1995 and determined the rate of brain tumors in subscribers wasn't higher than in those who didn't have a device.
Some experts said the Danish study bolsters the contention that casual cellphone use is harmless.
"This paper supports most other reports which do not find any detrimental effects of phone use under normal exposures," said Malcolm Sperrin, director of Medical Physics at Britain's Royal Berkshire Hospital, told Reuters.
Critics said the study was flawed because it didn't measure how much each person used their phone and it excluded corporate subscribers, who may have been the heaviest users in the 1990s.
The U.K. advocacy group Powerwatch also noted that people who didn't sign up for a phone until after 1995 were classified as "non-users" for the purpose of the study.
There have been contradictory findings and dueling studies for years on whether the radiation emitted by cellphones can breed tumors.
In May, the World Health Organization declared mobile phones a possible cancer trigger, lumping them in with coffee, booze and chloroform.
A month later, an international team of researchers debunked the cancer connection, saying there wasn't enough evidence.
Some advocates suggest that until it's clear whether cellphones cause cancer, people keep the phones away from their bodies and limit use by children.
Those who have many friends on Facebook have a brain that looks different than those who do not, according to a new study. Those with many Facebook friends were in the study, larger amygdala, a part of the brain among other things, manages memory and emotions. But it is unclear what caused what, if it is so that those who already have larger amygdala acquire more friends online, or if it is so that those who gain more friends get bigger amygdala gradually. Similar correlations, but in other parts of the brain, scientists have seen among those who have many friends in the physical world. In order to move forward thinking scientists do follow-up studies to see if the brain structures affected by how the subjects are using Facebook and the internet at large.

Apple's iOS mobile operating system changed the definition of what a smartphone could be when it launched in 2007 on the first-generation iPhone.
Each year since, we've seen the release of a new, more capable iPhone and annual updates to iOS that add new features for Apple's competitors to follow and features that allow iOS to catch up to its rivals too.
This week, with the release of the iPhone 4S, came the release of iOS 5 to the iPhone 3GS, iPhone 4 and first-generation iPad and iPad 2. And again, iOS plays a bit of catch-up with features while adding a lot of newness as well.
In all, Apple says there are more than 200 new features in iOS 5. I won't go over all them here as I haven't yet found all 200 for myself. However, the conclusion I've arrived at after days of testing iOS 5 is that this is the best and most complete version of iOS 5 to date.
Since iOS' initial release five years ago, iOS has been tweaked and improved and now has an answer for nearly every complaint I have for it. That's not to say that I don't have gripes with iOS 5 -- I do. But my complaints are now mostly limited to simply getting the operating system installed on my device -- something that shouldn't be a problem for those not rushing to install iOS 5 on day one.
In the video below, my colleague Michelle Maltais and I talk about what a buggy and cumbersome pain it was to install iOS 5 and even get iCloud up an running this week.
We also offer our take on some of the more prominent features in iOS 5 such as new multi-touch gestures, a notification center (finally), Twitter integration, the new Newsstand app folder, iMessage (Apple's answer to BBM) and handy location-based Reminders.
One item not covered in our video review is the number of improvements made to iOS' version of the Safari browser. The update to iOS 5 brings tabbed browsing and integration with Safari on your laptop or desktop for bookmarks and reading list. These additions make Safari much more useful by syncing across devices and pull a bit ahead of Android's browser with the addition of reading list integration, while catching up with tabbed browsing -- something Android has offered for a while now.
There are also a few features offered in iOS 5 we haven't had the chance to test out that we'll return to at a later date -- such as the Siri voice-command personal assistant app found only on the iPhone 4S and iTunes Match, a $25-per-year service (set to debut in October) that replicates an iTunes users' entire music collection, including songs not purchased from iTunes, in the cloud.
But even without Siri and without iTunes Match yet available, my opinion is that iOS 5 is the most polished and intuitive mobile operating system on the market today. I'd rank it above any version of Google's Android released thus far and Microsoft's Windows Phone software too.
I'm still delving into Windows Phone Mango and we'll have a detailed review into Mango on the Technology blog soon (maybe I'll change my tune in iOS taking the top spot by the time that's done with). And Google is set to release its all-new Android Ice Cream Sandwich OS next week. So while Apple may be on top with iOS 5, the competition will only getting tougher ahead.
Feel free to sound off on iOS 5 in the comments below.

Are those iOS backups taking up too much space on your boot drive? While there’s no built-in function in the iTunes preferences menu for moving the archive folder, it’s a simple procedure on most platforms. While others have mentioned this in the past, I haven’t come across a single page with instructions for all major operating systems. For reference, the instructions are below:
Mac OS X
- Close iTunes
- Move the existing ~/Library/Application Support/MobileSync/Backup/ folder to the destination drive (for example, named BigExternalDrive)
- Open a command prompt by launching Terminal and create a symbolic link using a command similar to the one below, replacing /Volumes/BigExternalDrive/Backup with the path to your destination:
1
ln -s /Volumes/BigExternalDrive/Backup/ ~/Library/Application\ Support/MobileSync/Backup
Windows Vista and Windows 7
- Close iTunes
- Move the existing C:\Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\ folder to the destination drive (for example, D:\)
- Open a command prompt and create an NTFS junction point using a command similar to the one below, replacing D:\Backup with the path to your destination:
1
mklink /J "C:\Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup" "D:\Backup"
Windows XP
- Close iTunes
- Download and extract this junction utility to your Desktop
- Move the existing C:\Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\ folder to the destination drive (for example, D:\)
- Open a command prompt an NTFS junction point using a command similar to the one below, replacing D:\Backup with the path to your destination:
1
cd Desktop
2
junction "C:\Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup" "D:\Backup"

Myocarditis and pericarditis are two complications that you can get the infection. In most cases it is harmless with mild symptoms, but sometimes the heart muscle or pericarditis is a serious and life-threatening condition. Contact the hospital emergency department if you have chest pain, palpitations and increased breathlessness.

NEW YORK | Mon Oct 3, 2011 4:24pm EDT
NEW YORK (Reuters Health) - College students' Facebook pages might hold clues to which of them are at risk for alcohol dependence and abuse, according to a new study.
Researchers found that students who had pictures or posts about getting drunk or blacking out were more likely to be at risk of drinking problems, based on a screening test. That was not necessarily the case for students who mentioned alcohol or drinking on their pages, but not in a way that showed that they drank too much or in unhealthy situations.
It's possible that Facebook pages could help schools find out who needs to be assessed for alcohol-related problems -- although privacy and ethical concerns might make that complicated, researchers said.
The question is whether "what's being found on these sites... is actually predictive of clinical conditions," said Dr. James Niels Rosenquist, a social media researcher and psychiatrist from Massachusetts General Hospital who wasn't involved in the new study.
The findings suggest that messages on Facebook sites do seem to be linked to what happens in the "real world," he told Reuters Health.
Dr. Megan Moreno from the University of Wisconsin-Madison led a team of researchers from her university and the University of Washington in Seattle who surveyed the Facebook pages, including photos and posts, of 224 undergrads with publicly-available profiles.
About two-thirds of those students had no references to alcohol or drinking on their pages. The rest of the pages mentioned or had pictures of social, non-problematic drinking or more serious and risky alcohol use, including riding in a car while drunk or getting in trouble related to drinking.
The researchers brought all the students in for a 10-question screening test used to determine who is at risk for problem drinking. That test assesses the frequency of drinking and binge drinking as well as negative consequences from alcohol use.
Close to six in ten of the students whose Facebook pages had references to drunkenness and other dangerous drinking scored above the cutoff showing a risk for alcohol abuse and dependence, as well as other drinking-related problems.
That compared to 38 percent of students who had more minor references to alcohol and 23 percent of those who didn't mention alcohol or drinking at all, according to findings published in the Archives of Pediatrics and Adolescent Medicine.
In addition, close to one in five Facebook-implicated risky drinkers said they had an alcohol-related injury in the previous year.
Moreno and her colleagues proposed that peer leaders such as residential assistants could be trained to use Facebook to see who is at risk for problem drinking, and refer those students to get screening. Or, parents and administrators could talk to a school's counselors if they were worried about alcohol-related content on a student's page.
"You might have someone who, if they write in a Facebook posting about being drunk... that might be a red flag," Rosenquist told Reuters Health.
But, he added, with social media "you get very small snapshots into people's lives," so perusing Facebook pages alone might not be enough to see who needs to be screened for alcohol problems.
And there are other concerns as well, he said, including how appropriate it is to go scouting on students' pages for certain information.
Moreno said that a college RA already has a connection with students and is there to look out for them -- and this study is showing that "there is some legitimacy in approaching students that you're worried about," including if that worry is coming from Facebook posts.
But, she added, "Paying attention to people's privacy concerns is really big."
Moreno suggested that universities could have links to the health center or to online screening tests show up as Facebook advertisements for students who use terms such as "blacked out" on their pages.
"With the targeted messaging, there's not that (feeling) that someone you don't know is creeping on your profile," she told Reuters Health.

So what, the universities will get access to the students profiles and send them messages either through facebook or e-mail warning them about their behavior, or suggesting some sort of intervention? I’m sure that’ll work out well. There is certainly a breach of ethics if this is permitted, and I doubt an intervention would have any benefits whatsoever. If I were identified as a problem drinker, I’d tell the people who identified me to **** off and mind their own business.
Anxiety about the economy and job security is making an impact on absenteeism, as stress is ranked as the most common reason for long-term absence, according to new research.
According to the Absence Management survey from the Chartered Institute of Personnel and Development (CIPD) and Simplyhealth employers that are planning to make redundancies see a rise in mental health problems to 51% of their workforce, compared to 32% of the workforce in those companies not planning redundancies.
The report also identifies a 50% increase in stress-related absence in the public sector, where uncertainty surrounding organisational change and the stability of the economy is making an impact, as job insecurity is a more common cause of stress, up 14% from last year to 24% this year.
Dr Jill Miller, CIPD Adviser, says: “The survey this year shows that stress is for the first time the number one cause of long-term sickness absence, highlighting the heightened pressure many people feel under in the workplace as a result of the prolonged economic downturn.
“Stress is a particular challenge in the public sector where the sheer amount of major change and restructuring would appear to be the root cause. To a large degree, managing stress is about effective leadership and people management, particularly during periods of major change and uncertainty.”
Overall employee absence levels remained consistent at 7.7 days per employee per year, while public sector absence has decreased from 9.6 days to 9.1 days.
