BAMAKO, MALI
   Malians woke up to a state of emergency after Friday’s assault on the Radisson Blu Hotel in the capital killed 20 people plus two assailants, according to a military commander.
   In addition to an American public health worker murdered in a terrorist raid on a luxury hotel in Mali’s capital on Friday, the 19 dead included six Russians, three Chinese, two Belgians and an Israeli national.
   Two gunmen who conducted the assault died after Mali Special Forces entered the hotel. Mali troops, backed by French and U. S. Special Forces, conducted a seven-hour operation Friday that ended the violence and led to the rescue of 170 hotel guests and staff held hostage during the siege. SANTA CRUZ,BRAZIL
   A wave of toxic mud travelling down the Rio Doce River in Brazil from a collapsed dam has reached the Atlantic Ocean, amid concerns it will cause severe pollution. The waste has travelled more than 500km since the dam at an iron mine collapsed two weeks ago. The contaminated mud, tested by the water management authorities, was found to contain toxic substances like mercury, arsenic and chromium at levels exceeding human consumption levels.
   In an interview, Andres Ruchi, director of the Marine Biology School in Santa Cruz, said that mud could have a devastating impact on marine life when it reaches the sea. He said the area of sea near the mouth of the Rio Doce is a feeding and breeding location for many species of marine life including the threatened leatherback turtle, dolphins and whales.

   A security hole that could allow attackers to access users’ personal data was inadvertently placed on Dell computers, the company has admitted. The hole represented a "profound security flaw" that could allow access to bank details and other personal data, experts said. Dell has issued guidance on removing the software that produced it.
   In astatement released on Monday, Dell acknowledged the vulnerability and linked to a guide on permanently removing the software that caused it. " We became aware that a certificate(eDellRoot), installed on our PCs, unintentionally introduced security vulnerability. The certificate was implemented as part of a support tool and intended to make it faster and easier for our customers. Customer security and privacy is a top concern and priority for Dell: we deeply regret that this has happened and are taking steps to address it. "

   Nearly 60 years ago, a crane was brought in to lift a huge computer ’capable of addition and subtraction’ into the disused Eldon Chapel across from our Chemistry building. Today, think about all the things the little microchip in your phone can do.
   Microbubbles will be to drugs and manufacturing what microchips were to computing. In the near future, microbubbles will float through the human body to carry a drug to its target. And beyond medicine, you’ll see how very small mixtures will revolutionise some manufacturing processes. Then, what’s a microbubble?
   Imagine a soap bubble that’s 100th the size of a human hair. It includes a gas core and a surrounding shell. Why would such a small bubble be useful? It already is. Microbubbles were developed in the 1990s to improve the clarity of ultrasound. They help measure blood flow in organs because their gas core reflects stronger ultrasound waves better than tissue does. Scientists started thinking, ’if these bubbles can safely travel around the human body, let’s get a drug to hitch a ride and be dropped off exactly where we want it to go. ’

   Disney dragged down the Dow Jones industrial average Friday after the media and entertainment giant said ESPN lost 3 million subscribers in the last year.
   Disney fell $3. 54, or 3 percent, to $ 115. 13, its biggest one-day loss since August. Late Wednesday, Disney disclosed that U. S. subscribers to its ESPN sports channel fell for the second year in a row, to 92 million as of Oct. 3, matching the lowest total since 2006. ESPN’s subscriber totals had hovered around 100 million for years.
   Disney has said that ESPN has lost subscribers, but investors appeared shaken by the size of the losses. Small but growing numbers of people are opting out of traditional cable TV bundles and buying smaller, less expensive groups of channels instead. Investors in media companies are worried about potential losses of subscribers and revenue.
