US kayaker's close encounter with great white shark

A kayaker is counting his lucky stars after a close encounter with a great white at a popular US resort. Walter Szulc was paddling near a Cape Cod beach at the weekend when he saw the shark's dorsal fin just behind him. Mr Szulc, 41, said he "paddled very fast" to shore in the eastern Massachusetts holiday spot. Experts say the ocean predator was probably drawn by an increased local population of its favourite snack, seals.

"I saw the fin out of the water. I looked down and saw the body and realised that part of the shark was underneath me, and I just proceeded to paddle," Mr Szulc said.

Mr Szulc, who arrived with his family at Nauset Beach in Orleans on Saturday, said it had been his first time kayaking in the ocean. His teenage daughter had mentioned recent local shark sightings, he added, although he did not expect to see one of the feared predators at such close quarters himself.

The beach was closed after Mr Szulc's brush with the shark, about 45 metres (150ft) from shore. It reopened afterwards and local officials said there had been no more shark sightings. "There have been reports of sharks in the past, but usually they are farther out, not this close to the bathing beach," said town beach director Lee Miller.

Android Jelly Bean roll-outs begin with Nexus devices

Google has started uploading the latest version of its Android system to users' smartphones. Owners of the HSPA+ version of Samsung's Galaxy Nexus - available in the UK, most of Europe and the US - are the first to receive the update.

Google says the Jelly Bean software offers an improved search experience. But it does not appear to have amended the system to take account of a patent row that briefly caused the Nexus phone to be banned from sale in the US. The update - also known as Android 4.1 - poses a direct challenge to Apple's voice-controlled "assistant" Siri.

Google says it has improved Voice Search so that it can display answers to spoken questions from sources including Wikipedia, the CIA World Factbook and Freebase - a community-run knowledge database. It has also introduced Google Now which is designed to offer information without the user having to actively trigger a query.

"Google Now tells you today's weather before you start your day, how much traffic to expect before you leave for work, or your favourite team's score as they're playing," said the firm in an update to the Nexus page on its Google+ social network.

Both features are potentially in breach of an integrated search patent filed by Apple. Last December the US Patent and Trademark Office granted the iPhone maker intellectual property rights to the idea of gathering search results from a variety of sources using different techniques, and then presenting them in "a unitary interface". The firm uses the innovation to power Siri.

A US court imposed a sales ban on the Galaxy Nexus in the country last week following a complaint by Apple that Samsung had infringed the patent by including integrated search functionality in the handset. Although the restriction was later lifted there had been reports that Google would alter Android to restrict its quick-search and voice-search facilities to web-based results.

The roll-out follows news from Microsoft that it has secured patent agreements with two more companies who install Android on their devices. The Windows Phone developer alleges that several of its inventions have been incorporated into Google's system and has filed lawsuits against companies which have refused to pay it a fee.

The latest manufacturers to sign a deal are the New York-based tablet maker Coby Electronics and its California-headquartered rival Aluratek. They join Samsung, LG, HTC and others who have also signed similar licensing agreements. Microsoft is still trying to secure payments from Google's Motorola hardware unit.
