Rio de Janeiro, Brazil
   The International Olympic Committee(IOC)has said that it sees no need to cancel, delay or move the Rio Olympic Games because of the Zika virus threat. However IOC medical director Richard Budgett said that it would continue to monitor the situation closely. Mr Budgett was responding to a call by Canadian health Professor Amir Attaran for the Games to be postponed or moved. Prof Attaran said that the influx of visitors to Brazil would result in the avoidable births of malformed babies. "If the IOC and the World Health Organisation(WHO)do not have the generosity of heart to delay the games to prevent children being born and disabled their whole lives, then they’re among the cruellest institutions in the world, " Prof Attaran said in a telephone interview with the Associated Press news agency.

   Forty-six people aboard a tourist catamaran were rescued after the vessel caught fire and sank on Australia’s Great Barrier Reef, police said. A police statement said 19 of those rescued were taken to hospitals in Bundaberg and Gladstone for treatment of non-life threatening injuries after the vessel sank late Wednesday.
   The 23-meter catamaran, Spirit of 1770, was returning to the town of 1770 after a day trip to Lady Musgrave Island when it caught fire and was abandoned 30 minutes later. Passengers and crew took to life rafts, Australian Broadcasting Corp. reported. The fire started in the engine room, ABC reported. The town of 1770 was named after the year that British explorer James Cook and the crew of HM Endeavour landed on that stretch of the Australian east coast.
Boston. United States
   Two bystanders and an off-duty deputy sheriff were hailed as heroes Wednesday for intervening when a mentally disturbed man went on a stabbing rampage at a home and a mall hours after leaving a hospital, killing two people and injuring at least five others. George Heath, a visual design teacher at the Regional Vocational Technical High School, was at the bar with his wife, Rosemary Heath. She said they had just ordered a drink when they heard a scream and saw DaRosa stabbing a young woman. Rosemary Heath said she pushed the woman out of the way and grabbed the back of DaRosa’s shirt. "My husband was struggling with him to get the knife away," she said. "I think he went down low on him to get him around the elbows so he couldn’t raise his arm up, and then he pulled his arm back and then stabbed my husband in the head. "
   George Heath, 56, later died. Mayor Thomas Hoye Jr. called Heath "certainly a hero. ""He stepped up," Hoye said. "He prevented a tragic situation from getting worse. "
   Rosemary Heath said Plymouth County Deputy Sheriff James Creed, who was off-duty and at the bar eating dinner, repeatedly ordered DaRosa to drop the knife. When DaRosa refused Creed fired one shot at his abdomen, killing him and preventing "further carnage. "
Phalodi, India
   A city in India’s Rajasthan state has broken the country’s temperature records after registering 51C, the highest since records began, the weather office says. The new record in Phalodi in the desert state comes amid a heatwave across India. The previous record for the hottest temperature stood at 50. 6C in 1956. The heatwave has hit much of northern India, where temperatures have exceeded 40C for weeks.
   The run-up to the Indian monsoon season is always characterised by weeks of strong sunshine and increasing heat but life-threatening temperature levels topping 50C are unusual.
   India declares a heatwave when the maximum temperature hits 45C, or five degrees higher than the average for the area in previous years.

   Scientists have designed flying, insect-sized robots that can perch and launch from ceilings. The findings, reported in the journal Science, contribute to a decade-long Harvard Microrobotics Laboratory project called "RoboBee". The robots in this study are programmed drones, each around the size of a 10 pence coin.
   Equipped with sensors, swarms of these small, relatively cheap robots could alert first responders to the most intense areas of forest fires or other natural disasters.
   Hovering microrobots run out of energy really quickly. Perching allows the robots to conserve energy. Detaching easily from a surface was another challenge. To solve these problems, the researchers designed a small, flat "landing patch" with an electrostatic charge that can be switched on and off. When switched on, the patch acquires a negative charge that makes it stick to nearby, more positively charged surfaces. And for the dismount, simply remove power to the patch.
