A new virus in liver cancer

Science Daily - Thu, 27/08/2015 - 3:16pm
More than a cause of a simple infection, viruses are often involved in the development of serious diseases. Such is the case with liver cancer, which often develops in an organ that has been weakened by hepatitis B or C virus. Researchers have just identified the role of a new virus, hitherto unsuspected, in the occurrence of a rare type of liver cancer.

New fossil skulls reveal insights about penguin brain evolution

Science Daily - Thu, 27/08/2015 - 3:16pm
Although flightless in air, penguins have a number of adaptations which allow them glide effortlessly through the water. And some of these adaptations are in an unlikely part of their anatomy -- their brains. Recent finds of fossil penguins from 35-million-year-old sediments in Antarctica have begun to shed light on the changes in penguin brains that accompanied their transition to water.

Analysis Reveals Almost No Real Women On Ashley Madison

Slashdot - Thu, 27/08/2015 - 2:56pm
gurps_npc writes: Ashley Madison claimed to have about 31 million men and 5.5 million woman enrolled. Those odds are not good for the men, 6:1. But unfortunately, most of those 'women' were fake. This researcher analyzed the data and found only 12,000 actual, real women using Ashley Madison. That means for every 7750 men, there were 3 women. There are reports that Ashley Madison paid people to create fake female profiles. Their website admits that 'some of the users may be there for "entertainment purposes."' The article itself is well written, including a description of the analysis. A charitable person would say that Ashley Madison was selling a fantasy, not reality. But a realist would say Ashley Madison is just a thief stealing money from lonely, unhappy men.

Taking a cue from nature: Turning alcohols into alkylating agents

Science Daily - Thu, 27/08/2015 - 2:17pm
Researchers have developed a dual catalyst system that directly installs alkyl groups -- fragments containing singly bonded carbon and hydrogen atoms that have extremely useful properties for drug discovery -- onto compounds called heteroarenes. The reported transformation is the first to successfully use alcohols as reagents in the so-called alkylation reaction.

North Dakota Legalizes "Less Than Lethal" Weapon-Equipped Police Drones

Slashdot - Thu, 27/08/2015 - 2:17pm
According to the Daily Beast, writes reader schwit1, North Dakota police will be free to fire 'less than lethal' weapons from the air thanks to the influence of a pro-police lobbyist. That means beanbags, tear-gas, and Tasers, at the very least, can be brought to bear by remote. It's worth noting that "non-lethal" isn't purely true, even if that's the intent behind such technologies. From the article, based partly on FOIA requests made by MuckRock into drone use by government agencies: The bill’s stated intent was to require police to obtain a search warrant from a judge in order to use a drone to search for criminal evidence. In fact, the original draft of Representative Rick Becker’s bill would have banned all weapons on police drones. Then Bruce Burkett of the North Dakota Peace Officer’s Association was allowed by the state house committee to amend HB 1328 and limit the prohibition only to lethal weapons. “Less than lethal” weapons like rubber bullets, pepper spray, tear gas, sound cannons, and Tasers are therefore permitted on police drones.

Humus depletion induced by climate change?

Science Daily - Thu, 27/08/2015 - 2:09pm
The yields of many important crops in Europe have been stagnating since the 1990s. As a result, the input of organic matter into the soil -- the crucial source for humus formation -- is decreasing. Scientists suspect that the humus stocks of arable soils are declining due to the influence of climate change. Humus, however, is a key factor for soil functionality, which is why this development poses a threat to agricultural production -- and, moreover, in a worldwide context.

How dynamin mediates membrane constriction and scission

Science Daily - Thu, 27/08/2015 - 2:09pm
Cells continually form membrane vesicles that are released into the cell. If this vital process is disturbed, nerve cells, for example, cannot communicate with each other. The protein molecule dynamin is essential for the regulated formation and release of many vesicles. Scientists have now elucidated this process and demonstrated how specific mutations impair the function of dynamin in disease.

Since-Pulled Cyanogen Update For Oneplus Changes Default Home Page To Bing

Slashdot - Thu, 27/08/2015 - 12:54pm
ourlovecanlastforeve writes: Nestled into GSMArena's report on the Cyanogen OS 12.1 update for Oneplus [ Note: an update that the story reports has since been pulled.] is this tasty bite: "...you'll find out that your Chrome homepage has been changed to Bing." Then it's casually dismissed with "Thankfully though, you can easily get rid of Microsoft's search engine by using Chrome settings." as if this were the most normal thing to have to do after an OTA update. Is this the new normal? Has Microsoft set a new precedent that it's okay to expect users to have to go searching through every setting and proactively monitor network traffic to make sure their data isn't being stolen, modified or otherwise manipulated?
