CBC.ca Player My thesis adviser and my agricultural ecosystems professor explaining the rationale for camolina inclusion in salmonid diets. In my nutrition class, we had looked at camlina, as well as some canola meals as partial and full replacements for fish meal and fish oil. You can see...

Report: Private Prisons Love Mass Incarceration, And Want Politicians To Love It Too | TPMMuckrakerPrivate prison companies have helped fuel government policies which lead to an increase in prison population and boost their profits, according to a recent report. The private prison...

A while back I posted a thread about biotechnology applications which are being used right now to help us, for example to identify strains of bacteria such as the one which caused so much havoc in Germany and other parts of Europe. The work in that case involved some gene sequencing to determine...

Can asbestos be used “safely”? - Science-ish - Macleans.ca This week talks are taking place in Geneva, in the latest round of the Rotterdam Convention, a program in the UN through which the parties involved ban pesticides and industrial chemicals, or place restrictions due to the health and...

Well, not really a shocking finding. The majority of science related stories are now written by reporters without any formal training in science. Financial difficulties have meant cut backs, and science reporting is kind of like art and music classes that get cut from tight education budgets...

Court Holds Prosecutor Personally Liable for Unconstitutional Search of Student Who Created a Parody Newsletter - FIRE After the United States Court of Appeals for the Tenth Circuit reaffirmed that "speech, such as parody and rhetorical hyperbole, which cannot reasonably be taken as stating...

Andem, is there any way we could have boolean searches when using the forums search function? Having only the or operator is not optimal for searching, in my experience.

How secure do you feel about making donations to public parties? The answer may change after today. Yesterday, hackers attacked the Conservative Party of Canada's webpage, announcing that Prime Minister Harper had been airlifted to a Toronto area hospital after choking on a hashbrown. Media...

Kind of surprised that there isn't a thread about this already, or maybe I'm looking in the wrong sub-forum... Anyways, last night officials announced that the most likely source of this E. coli outbreak is from bean sprouts grown in Germany, which is a huge embarrassment for Germany after...

A bit of frivolous lawsuit, and intimidation to boot. From their press release: Chico, California. – The ChicoBag Company, a reusable bag company, has announced it is the sole defendant in a lawsuit filed by Hilex Poly Company, LLC, Superbag Operating, LTD., and Advance...

A closed system when you're talking about thermodynamics has a precise meaning, it means that the system can exchange work and energy with it's surroundings, but not matter. An igloo can definitely exchange matter with it's surroundings... NOT all of it, that is a fact. As I've said multiple...

Yes, so the source of the heat hasn't changed, only something is blocking the radiation of heat away from that system (not closed). Cold frozen blocks of snow and ice. Greenhouse gases do exist whether you acknowledge them or not. The effect can be measured with infrared cameras, easily. Not a...

Yup, and getting colder.

So explain the temperature inside an igloo dumb beaver.

You are routinely posting this pseudo-scientific nonsense. Thermodynamics is much more than this fool wrote. It concerns the system, and it's properties. A system can warm up without changing the source. You for whatever reason, refuse to acknowledge that any matter with a temperature above 0 K...

You can test greenhouse theory in a lab, it doesn't require a greenhouse. But what TenPenny was commenting on, and you seem to have missed, is that an agricultural experiment in a greenhouse is not a proper analog for a planetary climate.

A french press is more than just the glass part...and it's nowhere near close to lab quality glassware.

I recently broke my french press, and I miss it! Haven't replaced it yet. Don't own anything else. Jamie just recently took up coffee, owing to her schedule at vet school, so I may have to invest in some more gear! At work we have a few coffee machines. The Keurig is very popular, so many...

So what? Brick is heavier than extruded expanded polystyrene.

Right. Your body cannot radiate as much heat away from it's body, so it warms. Less energy is escaping to space, the greenhouses gases prevent the escape of heat, so the planet warms. That is not violating thermodynamics anymore than your blanket which keeps you warm by retaining heat next to...
