Artificial fluorescent membrane lipid shows active role in living cells

Science Daily - Mon, 05/06/2017 - 12:55pm
Biological membranes, such as those surrounding animal cells, are made up of lipids and proteins. Because these molecules do not usually mix well, they are distributed within different regions of the membrane. These two lipids are required for the generation of cholesterol-dependent raft domains, which are necessary for signaling within the plasma membrane. However, it was not clear how SMs interacted with other molecules of raft domains, until researchers developed new fluorescent synthetic molecules that structurally mimic SMs and can be studied in live cells.

Study estimates amount of water needed to carve Martian valleys

Science Daily - Mon, 05/06/2017 - 12:53pm
A new study calculates the amount of water needed to carve the ancient network of valleys on Mars and concludes the planet's surface was once much more watery than previously thought. The study bolsters the idea that Mars had a warmer climate and active hydrologic cycle, with water evaporating from an ancient ocean, returning to the surface as rainfall and eroding the extensive network of valleys.

'Hail Mary' mechanism can rescue cells with severely damaged chromosomes

Science Daily - Mon, 05/06/2017 - 12:53pm
Safeguards for maintaining the integrity of chromosomes during cell growth and division can fail, and a cell may find itself trying to divide into two daughter cells with a loose chromosomal fragment drifting away from a broken chromosome. Researchers are studying a remarkable mechanism that carries broken chromosomes through the process of cell division so that they can be repaired and function normally in the daughter cells.

Moving On From Fire Phone Turmoil, Amazon Plans New Android Smartphones: Report

Slashdot - Mon, 05/06/2017 - 12:35pm
Reader joshtops writes: Amazon plans to have another go at selling its own branded smartphones, according to a new report. The ecommerce giant, which killed off its Fire Phone in 2015, is working on a new lineup of smartphones branded as 'Ice', the report said, citing unnamed sources. Unlike the Fire Phone -- for which Amazon focused largely on the US and a couple of other western markets -- the company is eyeing emerging regions like India for selling its new phones. Amazon's upcoming smartphones run the latest version of Google's Android operating system with Google Mobile Services (GMS) such as Gmail and Google Play, the people said. Incorporating Google Mobile Services in its devices is a major change in strategy for Amazon, which currently offers a range of Android tablets without Google apps on them. The smartphones are being referred to as 'Ice' internally, in what could be a move to distance itself from the disastrous Fire Phone brand, though it's not clear if Amazon will eventually bring the devices under the Ice name. A source cited in the story said the phones will ship with Alexa, Amazon's AI assistant.

Can Twitter Survive By Becoming A User-Owned Co-Op?

Slashdot - Mon, 05/06/2017 - 11:30am
What's going to happen now that Twitter's stock price has dropped from $66 a share to just $18? An anonymous reader quotes Salon: A small group of shrewd Twitter users and shareholders have come up with proposals to fundamentally restructure the way Twitter is controlled, to turn the company into a public service by removing the need to feed investors' ceaseless appetite for hitting quarterly growth benchmarks... Sonja Trauss, a Bay Area housing policy activist, and Twitter shareholder Alex Chiang proposed earlier this year a resolution for the company's recent annual shareholder vote to promote ways to get Twitter users to buy stock in the company, such as offering ways to buy shares directly through the Twitter website and mobile app. If many individual Twitter users each owned a small piece of the company, then they could participate collectively (through the annual shareholder voting process) in steering the direction of the company. The idea makes sense from a labor standpoint. Twitter's value comes from user's tweets, which provides the backbone for digital advertising revenue. Twitter also sells this user-generated data to third parties that use it mainly for market research. This bloc of user-shareholders could theoretically overtake the control major institutional shareholders...have over the company. Because a lot of owners of a few shares of the company would have little to lose if the stock price doesn't grow or wavers, Twitter would be less beholden to meeting Wall Street's often brutal expectations.
