Dialog says Apple can build its own power-management chips

FRANKFURT: Dialog Semiconductor on Monday said top customer Apple could design its own power-management chips rather than rely on the Anglo-German chipmaker but said it saw no impact on its business next year.
Shares in Dialog, which analysts reckon derives more than half of its revenue from Apple, lost more than a fifth last week following a media report that Apple could design its own power management integrated circuits (PMICs) for use in iPhones as soon as 2018.
“Dialog recognizes Apple has the resources and capability to internally design a PMIC and could potentially do so in the next few years,” Dialog Semiconductor said. “Dialog does not have reason to believe its current expectations of 2018 Apple business would be impacted by such potential actions by Apple.”
Dialog shares were 4.7 percent lower at 0825 GMT, the biggest decliners among stocks in Frankfurt’s technology index , which was up 0.6 percent.
The Nikkei business daily last week quoted one source as saying Apple would make about half the iPhone’s power-management chips starting next year, with another source saying this could be delayed until 2019. (http://s.nikkei.com/2Al5nSl)
Dialog, itself heavily reliant on the smartphone industry, said it was aware that in order to remain a key supplier to Apple it would have to continue to meet the US company’s “technology, quality, price and volume expectations.”


Thaw of Antarctic ice lifts up land, might slow sea level rise

Thaw of Antarctic ice lifts up land, might slow sea level rise

  • The fast rise of the bedrock beneath will lift ever more of the ice onto land, reducing the risks of a breakup of the sheet caused by warming ocean water seeping beneath the ice
  • The process was too slow to save the ice sheet from a possible collapse triggered by global warming

OSLO: Antarctica’s bedrock is rising surprisingly fast as a vast mass of ice melts into the oceans, a trend that might slow an ascent in sea levels caused by global warming, scientists said on Thursday.
The Earth’s crust in West Antarctica is rising by up to 4.1 centimeters (1.61 inches) a year, an international team wrote in the journal Science, in a continental-scale version of a foam mattress reforming after someone sitting on it gets up.
The rate, among the fastest ever recorded, is likely to accelerate and could total 8 meters (26.25 feet) this century, they said, helping to stabilize the ice and brake a rise in sea levels that threatens coasts from Bangladesh to Florida.
“It’s good news for Antarctica,” lead author Valentina Barletta of the Technical University of Denmark and Ohio State University told Reuters of the findings, based on GPS sensors placed on bedrock around the Amundsen Sea in West Antarctica.
Much of the West Antarctic ice sheet, which has enough ice to raise world sea levels by more than three meters (10 feet) if it ever all melted, rests on the seabed, pinned down by the weight of ice above.
The fast rise of the bedrock beneath will lift ever more of the ice onto land, reducing the risks of a breakup of the sheet caused by warming ocean water seeping beneath the ice.
The uplift “increases the potential stability of the West Antarctic Ice Sheet against catastrophic collapse,” the scientists wrote.
Last week, another study said that three trillion tons of ice had thawed off from Antarctica since 1992, raising sea levels by almost a centimeter — a worsening trend.
It often takes thousands of years for the Earth’s crust to reshape after a loss of ice. Parts of Scandinavia or Alaska, for instance, are still rising since the end of the last Ice Age removed a blanket of ice more than a kilometer thick.
A further report this month found that the West Antarctic ice sheet expanded about 10,000 years ago, interrupting a long-term retreat after the last Ice Age, because of a rise of the land beneath.
But it said the process was too slow to save the ice sheet from a possible collapse triggered by global warming.
One of the lead authors of that study, Torsten Albrecht at the Potsdam Institute for Climate Impact Research, told Reuters on Thursday: “The expected eight-meter (26.4-foot) uplift in 100 years in the Amundsen Sea region ... seems rather small in order to prohibit future collapse.”
