This week, how plants keep track of time, how scientists are breeding cereal crops with ancient varieties to boost diversity and yields, how insects carry viruses between plants, and the chemical in smoke that triggers fire-dependent plants to germinate. Plus, printing new body parts, the workings of tornadoes and the bug behind potato blight... Listen to this Showor If you want to discuss this show, or ask a question, this is the place to do it.

Rik Lapham asked the Naked Scientists:
I read all the Q & A's about it and I was wondering how much money monthly a person with a standard 18 cu ft fridge (maybe 3 or 4 cu ft for the freezer) would save filling it with water bottles?
My friend insists he saves $5 or $10 a month but I think he's exagerating.I know you're in the UK, so if you could give me a percentage of the total operating cost if dollard amounts are unfamiliar to you, I would love that.
I enjoy going to visit and cooking him dinner but those darn frozen water bottles fallingall over the place when I try to use the freezer are a pain! (I'm trying to convince him to eitherreplace with larger bottles of water or boxes filled with insulation.)

Paul McGovern asked the Naked Scientists:
My mother gets headaches fairly regularly.
What causes a headache?
Are headaches a modern life ailment i.e. 100 years ago did the same number of people suffer from headaches?
Do animals get headaches?

John Gamel asked the Naked Scientists:
During the seven decades of my life, I've discovered a number of salient points about excrement:
1. The droppings of carnivores are denser, more gooey, and more foul-smelling than those of vegetarians.
2. But, on the other hand, there is wide variation among the latter group. For example, rabbit droppings resemble tiny uniform pills, while (at the opposite end of the spectrum) cows deposit huge semiliquid puddles. During my childhood in Lower Alabama, we termed these "cow flops" (based on the sound they make when they hit the ground) or "cow pies" (based on their appearance when dry).
3. Horses fall somewhere in the middle by dropping apple-shaped and –sized fibrous turds.
4. Chickens, in a category of their own, drop small lumps that resemble wads of chewing gum.
My question is: since they all eat only vegetable matter, why so much variation?

Ali Rhayem asked the Naked Scientists:
We see objects in the universe because their light reaches us, so every time we look at the night sky, we see a snapshot of how objects looked like at various times in the past depending on when their light was emitted. The further and deeper we look the older the object is.
But is it at all possible to see the same object at two different stages of its evolution, i.e. at two different points in time, in a single snapshot?
If we think of this in discrete terms, as if the object (any form of matter or else) emits light at point A, moves away faster than light then emits light again at point B. Provided that the object emits the light at both A and B within the cosmological event horizon where light can still eventually reach us, the light from point A reaches us first then the light from point B, thus we see two images of the same object in a single snapshot.

Anton Lukas asked the Naked Scientists:
13.8 billion years ago the big bang created the universe. There was no space, matter. Time started then.
I do have a lot of questions. Can you answer some of them?
When was matter created?
Is the amount of matter still increasing?
Is the amount of dark energy increasing?
How can something be created from nothing?

Ryan Barthel asked the Naked Scientists:
I am writing a report on proton exchange membrane fuel cells for school, and the aspect which is confusing me is how hydrogen gas is split into protons and electrons at the anode of the system.
I know it has something to do with the platinum catalyst but I cannot find anywhere why platinum is good for this. Many thanks for the response!

Ray Gorman asked the Naked Scientists:
I am familiar with the idea of an expanding universe… That not just the distance between galaxies in increasing, but the ACTUAL space between galaxies (or everything for that matter) is expanding. Does this not alter the speed of light at various ages of the universe, especially if the speed of light is a constant? So, if you're looking at the universe from the "outside"- at 6.5 billion years ago, is the relative distance light travelled in a second LESS than it travels today since the SPACE itself has expanded?
Thanks, really enjoy the show over here in the colonies!

Marilyn Bawden asked the Naked Scientists:
Blood tests show that my daughter Sharon age 41years is suffering from "re-active glandular fever".
We don't know when she suffered the initial bout. We do remember that when she was in her late teens she was very fatigued for many weeks. Subsequently she suffered a similar episode whilst living in the UK and then a few years ago back here in South Africa .
In March this year the symptoms of severe fatigued reoccurred. Blood tests reveal that she has re active Glandular Fever. Her Doctor ordered that she should have 4 vitamin B injections over a period of 4 weeks. She was also given a tonic to take.
Over the past 4 weeks she has experienced high temperatures, headaches, sore throat, very painful glands particularly in her groin. She is of the opinion that the vitamin B injections have added to the severity of her symptoms and has decided not to have the 4th injection.
Her Doctor has said that as Glandular Fever is a virus, she needs to rest and wait for the symptoms to subside. Is there any form of treatment that can be given to help her back to full health and strength?
She is single, lives a lone and has a very demanding job. Tuesday was the first day sick leave day she has taken in over 15years.
