Submission + - Uber agrees to temporarily suspend service in Portland (cnn.com) 1

Submitted by mpicpp
mpicpp writes: Uber is standing down for the next three months in Portland, just one of the cities where it has run into trouble.

The company said it would stop picking up customers there for three months after the city sued, asking a judge to order Uber to stop operating until it is in compliance with safety, health and consumer protection rules.

But Uber fully expects to be back. In fact, this could be good news for Uber fans in the long-run.

The city has agreed to update its laws, creating a new regulatory framework for companies like Uber that tend to fall somewhere between a taxi and a ridesharing service. People use it by requesting a driver with a smartphone app.

Uber, which operates in 60 cities across 21 countries, has run into problems because its drivers do not always meet the city's regulations for taxi and car services.

Last week, for example, a judge in Spain temporarily blocked Uber because the Madrid taxi service said it was unfair to competition and not properly licensed.

Submission + - Scientists Discover That Exercise Changes Your DNA

Submitted by HughPickens.com
HughPickens.com writes: The human genome is astonishingly complex and dynamic, with genes constantly turning on or off, depending on what biochemical signals they receive from the body. Scientists have known that certain genes become active or quieter as a result of exercise but they hadn’t understood how those genes knew how to respond to exercise. Now the NYT reports that scientists at the Karolinska Institute in Stockholm have completed a study where they recruited 23 young and healthy men and women, brought them to the lab for a series of physical performance and medical tests, including a muscle biopsy, and then asked them to exercise half of their lower bodies for three months. The volunteers pedaled one-legged at a moderate pace for 45 minutes, four times per week for three months. Then the scientists repeated the muscle biopsies and other tests with each volunteer. Not surprisingly, the volunteers’ exercised leg was more powerful now than the other, showing that the exercise had resulted in physical improvements. But there were also changes within the exercised muscle cells’ DNA. Using technology that analyses 480,000 positions throughout the genome, they could see that new methylation patterns had taken place in 7,000 genes (an individual has 20–25,000 genes).

In a process known as DNA methylation, clusters of atoms, called methyl groups, attach to the outside of a gene like microscopic mollusks and make the gene more or less able to receive and respond to biochemical signals from the body. In the exercised portions of the bodies, many of the methylation changes were on portions of the genome known as enhancers that can amplify the expression of proteins by genes. And gene expression was noticeably increased or changed in thousands of the muscle-cell genes that the researchers studied. Most of the genes in question are known to play a role in energy metabolism, insulin response and inflammation within muscles. In other words, they affect how healthy and fit our muscles — and bodies — become. Many mysteries still remain but the message of the study is unambiguous. “Through endurance training — a lifestyle change that is easily available for most people and doesn’t cost much money,” says Sara Lindholm, “we can induce changes that affect how we use our genes and, through that, get healthier and more functional muscles that ultimately improve our quality of life.”

schnell writes: The New York Times Magazine has an in-depth profile of Marissa Mayer's time at the helm of Yahoo!, detailing her bold plans to reinvent the company and spark a Jobs-ian turnaround through building great new products. But some investors are saying that her product focus (to the point of micromanaging) hasn't generated results, and that the company should give up on trying to create the next iPod, merge with AOL to cut costs and focus on the unglamorous core business that it has. Is it time for Yahoo! to "grow up" and set its sights lower?

What I wonder is how long it will be before some mega rich person(s) decides to build a semi-permanent offshore city, not so much a rig, more a case of a huge boat that is actually anchored to the ground and you take boats TO it.
There'd be loads of technical hurdles, but given the sheer size of such a construction, the issues of waves would be lesser, more so if it is designed properly to deal with them. (not to mention the use of large-scale wave guides similar in design to metamaterials, which is being tested on some oil rigs last I remember)

I'm not sure what the benefit of that would be over the very large mega-yachts the super-rich currently use - they're mobile, so they get the benefits of going to places around the world in luxury, plus being able to move out of the way of bad weather, etc.

I suppose the possible sheer _scale_ of a floating city has an appeal as a display of wealth to some.

Submission + - Google Strikes Deal With Verizon to Reduce Patent Troll Suits (wsj.com)

Submitted by mpicpp
mpicpp writes: Google Inc. and Verizon Communications Inc. struck a long-term patent cross-license agreement to reduce the risk of future patent lawsuits, the latest in a string of deals that signal a slowdown after years of aggressive patent wars.

The deal effectively bars the companies from suing each other over any of the thousands of patents the companies currently own or acquire in the next five years. It also protects the companies if either sells a patent to another company, and that company attempts a lawsuit.

“This cross license allows both companies to focus on delivering great products and services to consumers around the world,” said Kirk Dailey, Google’s head of patent transactions.

Submission + - China officially became the world's largest economy, ahead of the United States

mrspoonsi writes: For the first time in 150 years, the USA has lost its title of the largest economy in the world to China. China officially became the world’s largest economy, ahead of the United States, according to the International Monetary Fund (IMF). According to the latest figures of the International Monetary Fund (IMF) just released in December 8th, 2014, China has come ahead the United States as the world’s largest economy. China’s GDP will indeed reach 17600 billion in 2014 against 17400 billion for the United States. These data are calculated using the method known as “purchasing power parity”, which is economically significant. It measures the purchasing power of different currencies in a common unit as opposed to changes in exchange rates. Now China represents 16.5% of the global economy in terms of real purchasing power, ahead of the US, 16.3%. According to IMF estimates, the gap should continue to widen in the coming years. By 2019, China would reach more than 26,800 billion of national wealth, against just 22,000 billion for the United States. The United States had become the leading economic power in 1872 after overtaking Britain.

Submission + - What Will Microsoft's 'Embrace' of Open Source Actually Achieve? (dice.com)

Submitted by Nerval's Lobster
Nerval's Lobster writes: Back in the day, Microsoft viewed open source and Linux as a threat and did its best to retaliate with FUD and patent threats. And then a funny thing happened: Whether in the name of pragmatism or simply marketing, Microsoft began a very public transition from a company of open-source haters (at least in top management) to one that’s embraced some aspects of open-source computing. Last month, the company blogged that .NET Core will become open-source, adding to its previously open-sourced ASP.NET MVC, Web API, and Web Pages (Razor). There’s no doubt that, at least in some respects, Microsoft wants to make a big show of being more open and supportive of interoperability. The company’s even gotten involved with the .NET Foundation, an independent organization designed to assist developers with the growing collection of open-source technologies for .NET. But there’s only so far Microsoft will go into the realm of open source—whereas once upon a time, the company tried to wreck the movement, now it faces the very real danger of its whole revenue model being undermined by free software. But what's Microsoft's end-goal with open source? What can the company possibly hope to accomplish, given a widespread perception that such a move on its part is the product of either fear, cynicism, or both?

Submission + - Brain-Like Circuits Can Mimic Pavlov's Dogs (insidescience.org)

Submitted by benonemusic
benonemusic writes: A materials scientist at Harvard University and his colleagues have invented a new type of transistor-based electronic system that can mimic the plasticity of the brain by learning, unlearning and storing memories.The researchers constructed their device using films of samarium nickel oxide (SNO). When placed in contact with an ion-based liquid, SNO's electrical conductivity can be affected over the long term. The researchers used their electronic system to conduct versions of Pavlov's experiments with dogs, in which dogs associated food rewards with a bell ringing. The electronic system detect that two electrical stimuli are linked if they repeatedly came at the same time, and unlearned this connection if these two stimuli stopped coming at the same time. The circuits could also store patterns of electrical signals they experienced, mimicking how the brain stores memories. These devices can serve as "an electronic platform to probe fundamental problems in neuroscience," said lead researcher Shriram Ramanathan, a materials scientist at Harvard University.

Submission + - How Birds Lost Their Teeth

Submitted by Anonymous Coward
An anonymous reader writes: A research team from the University of California, Riverside and Montclair State University, New Jersey, have found that the lack of teeth in all living birds can be traced back to a common ancestor who lived about 116 million years ago. From the article: "To solve this puzzle, the researchers used a recently created genome database that catalogues the genetic history of nearly all living bird orders--48 species in total. They were looking for two specific types of genes: one responsible for dentin, the substance that (mostly) makes up teeth, and another for the enamel that protects them. Upon finding these genes, researchers then located the mutations that deactivate them, and combed the fossil record to figure out when those mutations developed. They concluded that the loss of teeth and the development of the beak was a two-stage process, though the steps basically happened simultaneously. The paper states: 'In the first stage, tooth loss and partial beak development began on the anterior portion of both the upper and lower jaws. The second stage involved concurrent progression of tooth loss and beak development from the anterior portion of both jaws to the back of the rostrum.'"

Submission + - Canada Waives Own Rules, Helps Microsoft Avoid US Visa Problems

Freshly Exhumed writes: Citizenship and Immigration Canada has granted an unprecedented exemption to Microsoft that will allow the company to bring in an unspecified number of temporary foreign workers as trainees without first looking for Canadians to fill the jobs. No other company in any other field has been granted such an exemption, and it does not fall within any of the other categories where exemptions are normally given, according to a source familiar with process, effectively creating a new category: the Microsoft Exemption. Microsoft Canada did not immediately respond to questions about the deal, but in an interview earlier this year with Bloomberg Businessweek, Karen Jones, Microsoft’s deputy general counsel, said the deal will allow Microsoft to bypass stricter U.S. rules on visas for foreign workers. The entire issue of temporary foreign workers has been as blisteringly hot a topic across Canada as it has been in the USA.
