Where does Phlegm come from?
|
 It's National Pathology Week 2010 and to celebrate the launch we're joined by pathologist Dr Suzy Lishman to take on your science questions! We'll find out where phlegm comes from, how petroleum jelly helps healing and the weight of red blood cells synthesised in a human lifetime. Also, can you concentrate lasers with lenses, why does an open carport stop frost, and if carnivorous plants photosynthesise, why do they need to eat insects? Plus, how researchers in Scotland are sniffing out pollution with such sensitivity, they can detect forest fires all the way from Canada! In Kitchen Science, Dave reads his credit card using rust!

New way of making washing machine resistant waterproof cotton fabric.
Scientists studying tumour samples pancreatic cancer victims have made a surprising discovery - the disease appears to take a very long time to develop before it begins to spread.
Dr Andrew Howard explains how their observations suggest that up to one in five stars like our Sun may have Earth-like planets orbiting them. We find out why this doesn't increase the likelihood of finding life, but may make us question some of the theories about planet formati...
New form of graphene based reconfigurable transistor has been developed.
In a study that informs our understanding of how the brain allocates attention to different stimuli, scientists have successfully enabled human volunteers to choose between images on a computer screen just by altering their thoughts.
I recently began renting a car port from my landlord. Though it is
little more than a roof, fully exposed to the elements, I found that
there was no frost on my car windows this morning. Yet not eight feet
away, a car parked outside the car port had a thick layer of frost on

Hi Chris,
Thank you SO very much for all your truly informative topic's of discussion. You just reaffirm how small we really are in this spectacular universe of ours!
Chris, I hope this is not a stupid question, but something has puzzled me a little bit in the observation o...
Dr Suzy Lishman joined us this week to introduce National Pathology Week 2010, and to answer your questions on pathology...
Can you possibly ask Dr Lishman exactly what steps I would need to take to work in Pathology. I'm fascinated post mortems and cause of death investigations. I am planning to study medicine, but is that 100% necessary to get to 'the slab'. Many thanks.
Dear Naked Scientists,
I was wondering how wounds heal when a lot of petroleum jelly or neosporin is applied to the wound? What does the body do with the foreign material? Absorb it, grow through it? Just wondering if anyone knew.
Thank you all!

I want to know if you can take ten already very powerful lasers, shoot into the edge of a magnifying concave lens that shoots them into the edge of another lens of the same kind and keeps doing so a couple times and then directing them out of a final lens in a single concentrated...
In a recent show you explained that a baby populates its intestinal flora by swallowing the muck it encounters while passing through the birth canal. What happens when a baby is born by caesarian section? Is the flora as good as it would have obtained by a normal vaginal delivery...
why do carnivore plants eat insects if they are capable of photosynthesis?
Predicting how the Earth’s climate is likely to change is one of the toughest challenges facing science, one that as we know is not without its controversies. To build accurate simulations of the climate, scientists need raw data and Planet Earth podcast presenter Richard Holli...
Good day Chris. I listen to 702 here in Johannesburg regularly. My wife sadly passed away at age 49 due to a brain aneurysm. This was very recently. I ask the neuro surgeon to explain what happened. He tried to explain but I was emotional and maybe did not listen properly. They d...
In summer, air humidity has us feel hotter as there's less evaporation. In winter, it works to feel colder. Why is it opposite?
I understand about allergies, how people can become allergic to things as they go along in life, but what I’d like to know is, how can a baby be born that is allergic to breast milk and all forms of milk? What happens?

Why when we cut something, its atoms don't get cut? Or why when we break things, there atoms don't break?
I've been a bit sick lately, and I've been wondering where all the yellow phlegm I've been coughing up comes from.
I understand that there's a tube connecting my lungs with my mouth, but I don't see where so much phlegm can be held.
Can you help?
Love the show
