Cancer risk if you use mobile for 30 min a day: Study

Talking on a mobile phone for more than half an hour a day could increase the risk of brain cancer by up to 40 per cent, a study has indicated.

The biggest investigation of its kind found that people who regularly held long conversations over many years might have an increase in the risk of developing a tumour.

But the researchers said the results were not conclusive and that -- even if the risks were real -- it would equate to just a few hundred more cases in Britain.

Despite scientists in 13 countries contributing to the 10-year, 15-million-pound Interphone project, they said the findings were open to statistical error, The Daily Telegraph reported.

The study appeared to show that, for most people, there was no link between the amount of time spent on the phone and the susceptibility to brain tumours.

But researchers could not rule out that heavy use -- which is becoming more common now -- would pose a risk in the long term.

Elisabeth Cardis of the Centre for Research in Environmental Epidemiology in Barcelona, who led the study, said: "We can't just conclude that there is no effect. There are indications of a possible increase.

"We're not sure that it is correct. The indications are sufficiently strong... To be concerned."

British scientists involved in the study, however, played down the risk, saying the research was inaccurate because it involved asking patients to recall their use over the last 10 years.

"Facebook Tests a New Feature To Let Users Enjoy Events Togather"

Facebook is testing a new feature to let users share events that they are interesting in attending to, on their "Stories" so that they can coordinate with friends and enjoy events together.

According to a TechCrunch report, the test will involve a new option to "Share to Your Story" that appears when you visit an event's page on Facebook.

"If shared, friends will see a tappable sticker within your Story that includes the event details and lets friends respond that they're also 'interested' right from the Story itself," the report added.

Friends also can tap on the sticker in the Story to visit the event page.

"There's also a link to the event page built in and a way to start a group chat on Messenger with friends who responded," said The Verge.

The test is currently rolling out to users in the US, Mexico and Brazil.

To use the new test feature, go to the Events page, click "Share" below the date and time of the eve…

Largest Spike in Hate Crimes Since 9/11, Says a Report

The number of hate crimes reported in the United States jumped by 17% last year, the largest increase since 2001 when the terrorist hijackings on 9/11 fueled a surge in attacks on Americans of Muslim and Arab ancestry.

A total of 7,175 hate crime incidents were reported to the Uniform Crime Reporting (UCR) Program in 2017, up from 6,121 in 2016, said the UCR Program's annual Hate Crime Statistics report, Xinhua reported.

It's the third year in a row the FBI has reported an increase in hate crimes. The number of hate crimes in 2016 rose about five percent from 2015.

The 2017 incidents encompass 8,437 total offences, meaning some involved multiple criminal charges.

According to the report, the most common bias categories in single-bias incidents were race/ethnicity/ancestry (59.6 percent), religion (20.6 percent), and sexual orientation (15.8 percent).

The victims represented a cross section of society, with African-Americans and Jews the most frequently targeted victims. Of 34…

2.2 bn Facebook Users Must Log Out, Re-login Across Devices, Says Experts

After Facebook admitted that hackers broke into nearly 50 million users' accounts by stealing their "access tokens" or digital keys, cyber experts on Saturday warned over 2.3 billion users to log out and log back into Facebook, or any of third-party apps that use Facebook login.

Facebook has reset the access tokens of almost 50 million accounts it knew were affected. It has also taken the precautionary step of resetting access tokens for another 40 million accounts that have been subject to "View As" look-up in the last year.

"For now, logging out and back in is all that is necessary. The truly concerned should use this as a reminder and an opportunity to review all of their security and privacy settings on Facebook and all other social media platforms," Chester Wisniewski, Principal Research Scientist with global cyber security major Sophos, told.

According to Dr Gary McGraw, Vice President of Security Technology, Synopsys (Software Integrity Group)…
