Journal Journal: Human stem cells repair rat hearts damaged by heart attack

Journal by stemceller
When human heart muscle cells derived from embryonic stem cells are implanted into a rat after a heart attack, they can help rebuild the animal's heart muscle and improve function of the organ, scientists report in the September issue of Nature Biotechnology. The researchers also developed a new process that greatly improves how stem cells are turned into heart muscle cells and then survive after being implanted in the damaged rat heart. The findings suggest that stem-cell-based treatments might

Submission + - Dell laptops still exploding (consumeraffairs.com)

bl8n8r writes: "It "looked like fireworks which would have been cool had it not been in my house." said Doug Brown of Columbus, Ohio. Brown, a Network Administrator, called 911 last week when the Dell 9200 laptop burst into flames in his house. Emergency response units included two pumpers, a ladder truck, a bamalance, the HAZMAT unit, and a battalion chief. When Doug phoned Dell to inquire about liability, he was asked if he had insurance. It's not clear if Doug's laptop is one of the earlier models recalled by Dell; a Macbook is cited in TFA for allegedly burning down a house in Australia as well as another instance of a suspect Dell laptop burning down a pickup truck in Nevada. If the burning battery issues are going to continue to be a problem, who's going to be responsible for losses? Insurance companies, Laptop makers, Battery vendors, and consumer negligence could presumably be cited in all cases."

Ape-Human Split Moved Back By Millions Of Years 390

Posted by kdawson from the everything-you-know-is-wrong-again dept.
E++99 writes in to let us know about a development in paleo-anthropology. It seems that up until now, scientific consensus has placed the divergence of man from the ape line five to six million years ago (based on "genetic distances"). But newly discovered fossils in Ethiopia place the divergence at least twice as far back, and perhaps as long ago as 20 million years. They also largely put to rest any doubts that man and modern apes both emerged from Africa. From the article: "The trail in the hunt for physical evidence of our human ancestors goes cold some six or seven million years ago... Beyond that... fossils of early humans from the Miocene period, 23 to five million years ago, disappear. Fossils of early apes especially during the critical period of 14 to eight million years ago were virtually non-existent — until now... [T]he new fossils, dubbed 'Chororapithecus abyssinicus' by the team of Japanese and Ethiopian paleo-anthropologists who found them, place the early ancestors of the modern day gorilla 10 to 10.5 million years in the past, suggesting that the human-ape split occurred before that."

Microsoft Goes Head-to-Head With IBM 274

conq writes "BusinessWeek has a piece on Microsoft's latest announcements that it is going after large-business computing, a realm that IBM currently has a stronghold on." From the article: "In both cases, the company has fashioned 'enterprise' versions of the products with additional security and collaboration-enabling features for sale to large businesses. Microsoft has spent $20 billion over the past three years on these upgrades, and Ballmer says it will spend $500 million over the next year marketing them to corporations. 'We're unlocking the next wave of growth for Microsoft,' Ballmer predicted during a press conference after his speech." We've previously discussed Microsoft's plans for IBM.
