Lab test commonly used to assess water toxicity may not predict effects on field populations

Science Daily - Mon, 04/05/2015 - 3:29pm
Hyalella azteca are invertebrates that are widely used for sediment and water toxicity studies. Investigators have found that H. azteca collected from sites influenced by agricultural/urban runoff are as much as 2-times less sensitive to pyrethroid insecticides than lab-grown H. azteca. In contrast, the insecticide sensitivities of H. azteca collected from undeveloped sites beyond the influences of agricultural/urban runoff were similar to those of lab-grown populations.

Former HP CEO Carly Fiorina Announces Bid For White House

Slashdot - Mon, 04/05/2015 - 2:53pm
seven of five writes: According to Reuters, "Former Hewlett-Packard Co Chief Executive Carly Fiorina announced on Monday she is running for president, becoming the only woman in the pack of Republican candidates for the White House in 2016. ... Fiorina registers near the bottom of polls of the dozen or so Republican hopefuls and has never held public office. But she has already attracted warm receptions at events in the early voting state of Iowa where she is positioning herself as a conservative, pro-business Republican highly critical of Democratic candidate Hillary Clinton. Fiorina was forced by HP to resign in 2005 as the tech company struggled to digest Compaq after a $19 billion merger." As part of her announcement, she said, "I think I'm the best person for the job because I understand how the economy actually works. I understand the world, who's in it, how the world works." I'm sure we'll soon begin hearing from all the HP employees, current and former, who have nothing but love for Carly F.

Ubuntu 15.04 Received Well By Linux Community

Slashdot - Mon, 04/05/2015 - 1:29pm
jones_supa writes: Canonical released Ubuntu 15.04 a couple of weeks ago, and it seems that this release has been a success. The community is mostly reporting a nice experience, which is important since this is the first Ubuntu release that uses systemd instead of upstart. At Slashdot, people have been very nervous about systemd, and last year it was even asked to say something nice about it. To be fair, Ubuntu 15.04 hasn't changed all that much. Some minor visual changes have been implemented, along with a couple of new features, but the operating system has remained pretty much the same. Most importantly it is stable, fast, and it lacks the usual problems accompanied by new releases.
