Brain scan technology could save babies’ lives

Filed under: — Aviran Mordo

Researchers at UCL (University College London) are developing a portable brain scanner which could help save the lives of premature and newborn babies in intensive care by avoiding to move them to conventional scanning facilities. A current prototype combines the advantages of both magnetic resonance imaging (MRI) and ultrasound. It uses optical tomography to generate images showing how the brain is working and a new generation should be ready by 2008 and such scanners should be commercially available shortly after.

Virtual Reality Could Help Diagnose Heart Conditions

Filed under: — Aviran Mordo

Virtual reality that allows doctors to visualise the heart in three dimensions could help in the diagnosis of heart conditions. A pilot study published today in the open access journal Cardiovascular Ultrasound reveals that doctors can diagnose heart conditions quickly and easily from virtual three-dimensional animated images or ‘holograms’ of the heart. Three-dimensional (3D) holograms allow doctors to ‘dive’ into the beating heart and see interior parts of the organ.

Annemien van den Bosch and colleagues, from Erasmus MC University Medical Center Rotterdam in The Netherlands, projected ultrasound-generated 3D images of hearts (echocardiograms) in a specially designed four-walled room called the I-Space. In the I-Space, images are projected on three of the walls and the floor, which results in an animated hologram floating in space in front of the viewers. The viewers wear a pair of glasses with polarising lenses allowing them to see the hologram with depth.

Van den Bosch et al. asked ten heart specialists to analyse the holograms of patients with a heart defect that affects the shape of an inside part the heart, and of patients with a healthy heart. The doctors learnt how to use the equipment and were able to virtually ‘cut through’ the heart to see inside, using a virtual pointer, within ten minutes. The ten doctors could all distinguish healthy from unhealthy hearts and make the correct diagnosis within only ten minutes.

English-Speaking Web Users a Minority on the Internet

Filed under: — Aviran Mordo

According to a study published by Byte Level Research, less than 30% of the world’s Internet users are native-English speakers. By 2010, that number will drop to less than 25% as such emerging markets as China, Russia, and Brazil drive millions of non-English-speaking people to the Internet.

“This data makes clear that the next Internet revolution will not be in English,? said John Yunker, president of Byte Level Research. “While English isn’t becoming any less important on the Internet, other languages, such as Chinese, Russian, Spanish, and Portuguese, are becoming comparatively more important. Web globalization will become increasingly vital to succeeding in this emerging global marketplace.”

Filed under: — Aviran Mordo

Visa USA acknowledged Saturday that a U.S. merchant “may have experienced a data security breach” that compromised credit card account information.

The statement came in response to a News.com inquiry related to customers whose Visa debit cards had been put on fraud watch or deactivated due to a security breach. The customers include a San Francisco Bay Area man whose Wells Fargo-issued card had been deactivated and a couple in Ohio whose card was placed on a watch.

In its statement issued Saturday, Visa said that after it learned “of the compromise, Visa quickly alerted the affected financial institutions to protect consumers through independent fraud monitoring and, if needed, reissuing cards.”

A Visa representative said Saturday that no other information was available at this time, including the name of the merchant, the number of accounts involved or when the event occurred.

Google has right to sell its AOL stake by ‘08

Filed under: — Aviran Mordo

Google will have the right to sell its new 5 percent stake in America Online as soon as July 1, 2008, according to regulatory filings by both Google and Time Warner, AOL’s parent.

On Tuesday, the companies announced that Google would buy the stake in AOL for $1 billion, saying the move represented a vote of confidence in AOL’s plans to transform itself from a shrinking provider of dial-up Internet access into a series of advertising-supported Web sites.

Friday’s filings say that starting two and a half years into the five-year agreement, Google will have the right to force Time Warner to register its shares in AOL with the Securities and Exchange Commission. This would allow Google to sell the shares on the public market. Time Warner has the option to buy the shares back for cash or Time Warner shares at an appraised value.
