+ - Bees prefer nectar laced with Neonicotinoids->

Submitted by Taco Cowboy
Taco Cowboy writes: Neonicotinoids are a class of neuro-active insecticides chemically similar to nicotine

Neonicotinoids kill insect by overwhelming and short-circuting the insects' central nervous system (See http://lee.ifas.ufl.edu/Hort/V... )

Shell and Bayer started the development of Neonicotinoids back in the 1980's and 1990's

Since this new group of pesticide came to the market the bee population have been seriously devastated in regions where the pesticide are been widely used

In 2008 neonicotinoids came under increasing scrutiny over their environmental impacts starting in Germany

In 2012, studies have shown that neonicotinoid uses are linked to crash of bee population (See http://usnews.nbcnews.com/_new... )

New studies, however, have discovered that bees prefer nectars that are laced with neonicotinoids, over nectars that are free of any trace of neonicotinoids (See http://www.rsc.org/chemistrywo... )

According to researchers at Newcastle University the bees may "get a buzz" from the nicotine-like chemicals in the same way smokers crave cigarettes

BBC also covers this case (See http://www.bbc.com/news/scienc... )

What an unscrupulous being:

Also in March 2015, the parents of a young child suffering from brain cancer, whom Gibson had befriended, came forward to report that they had been unaware that Gibson had earlier been claiming to be fundraising for their child's treatment on their behalf. The family stated they had not known about Gibson's claim to be charity fundraising on behalf of the child, and the family had never received any funds from her or TheWholePantry. The family suspected Gibson had been using information gleaned from the family's experiences to underpin her own claims to having brain cancer.

"That guy" is Eric Meyer, and his blog post might have become a "thing" because he is rather known in the field. I'm not specifically addressing this to LaurenCates, but rather those that gave Meyer some flak here on /. at the time: read both the original post and a second post. He didn't knock the developers and designers at Facebook, but after having gone through the worst that a parent can have to go through, he tried to "increase awareness of and consideration for the failure modes, the edge cases, the worst-case scenarios" in the industry. I've been reading his posts for a long time, he's a level-headed, active guy not prone to whining.

You are right. Most people apparently don't push hard enough when performing their first CPR, I guess that's what our instructor meant when he said that broken ribs (as a result of CPR by non-professionals) are usually caused when pressure is not applied to the sternum from the top. Nonetheless, he continued to underline the importance of a timely help, no matter how small, even if not performed perfectly or professionally.

The instructor also touched all of the other points you raised (including the first round of CPR). For the better part of the day he covered what to do when no AED is available and you are on your own with a patient. I really liked this class. None of us is a pro after a day-long course, but it really conveyed the message that even us lay people can make a difference until the trained professionals arrive.

In Italy it is now obligatory for sports clubs to have an AED and certified people who can use it. I took a day-long CPR/AED class just two weeks ago, together with other members of our club. The device is actually really easy to use - press a button, listen to the directions, place the pads and hope for the best. But when the machine can't produce a shock (for the reasons outlined by QQBoss above) one still needs to perform CPR, and that's what the biggest part of the course was about.

I second QQBoss and encourage everyone to take a First Aid/CPR/AED class. You can't do anything wrong - once a person is unconscious and is not breathing normally, it is just a question of time before they completely shut down. By acting immediately and administering First Aid until the cavalry arrives you can help raise their chances of survival and minimize possible collateral damage and recovery time. Should you crack a person's rib during CPR you were probably doing it wrong, but the fact that they are able to complain means that you have contributed to saving their life (and in many countries/jurisdictions you are protected by Good Samaritan law).

The decision doesn't have to be logical; it was unanimous.
