There was an article in Natural History last spring that described the
hunting practices of "predatory" fungi.  As I recall, some mushrooms
capture nematode worms by constricting around them in just this
fashion.  I can't recall whether or not the article mentioned if
individual cells were toroidal, or if topologically spherical cells
linked to form a ring.  Do you remember EB or should I dig it out?

This is averaged across the whole day.  An average cyclist can output 75
watts (from "Bicycling Science").  If I remember correctly that refers
to journeys up to about one hour duration.  The efficiency of muscle is
estimated as about 25%, so another 225 watts should come out as heat. 
Muscle powered aircraft are kept in the air with sustained outputs of
about 300 watts.  Whole body heat should then be up to 1200 watts, though
that is an extreme case.  I don't know how much work you have to do to
stay on a motor bike.  If you assume that the average rider is not
willing to provide more than 75 watts the 225 watts whole body heat
should be a reasonable estimate, though not the maximum possible.

HI,

I am a mechanical engineering student in the process of completing my senior 
project.  This project is to design, build and test a thermoelectric
cooling system for a motorcycle helmet.

For sometime, I have been tring to learn the rate of heat dissipated or
lost by the human head in a normal room enviroment.  I have been through
the journals and cd roms at school looking for this information.  I have
been given many suggestions, but none which were documentable.

Please, If ANYONE out there knows of a article, journal or other reference
which may contain this information pleas write me.  Also if you have           
suggestions on where to write please contact me.

For the initial computer models, I have been using the numbers given to
me, but for the final model and the report my team (and professors)
require a documentable source.

Thank you for your help,

	That makes them omnivores in my book which is why I agreed
with Kathleen Hunt (???) that the category of omnivory was
conspicuously missing from consideration.

	That said, my point was simply that the presence or absence of
forward facing eyes was probably minimally informative about current
dietary habits of primates.

Yes.  It's an interesting story.  Screwworms

liferate, while folks worked out some way for
US technicians and scholars to co-operate with
a country that's outside the Pale for the US

When did this all happen?  Sometime between
1989 and 1991, by my recollection.  For leads

example, *Science*.  That's the one mass-distri-

Not really. The rate of heat transfer in the water will be quite
different to the rate in air, which is what David is interested in.

A lot of things will affect the amount of heat leaving the head.
Air temperature, rate of air flow over the head (if any), whether the
person has hair or is bald, whether they are sweating or not, the size
of their ears ;-), and anything else I can't think of off the top of my
head. If you are controlling the air temperature and flow conditions
inside your helmet, then maybe you could enclose someone's head in a box
with roughly the same conditions, and measure the temperature rise of
the air inside the box over time. Maybe you could examine a variety of
different conditions. Maybe you don't need or want to go to this much
effort.
I doubt you will just be able to get a simple figure which is accurate.

I am almost sure the information exists somewhere. . .  
What is the difference in the chemical makeup of a seed (any will
do, but preferably common food seeds such as sunflower) after it
is sprouted?  I once heard that a seed converts some of its fat

Subject: Genetic clock
Organization: Rogaland University Centre
Date: Mon, 12 Oct 1992 12:57:36 GMT

    In genetic evolutionary biology one often talks about the genetic clock, a
dating technique which uses the difference in various genomes to estimate the
time of divergence. A controversal aspect of the genetic clock is that the
originators of the technique assume that the divergence is constant through time. 
Many argue that evolution is not a linear process and hence divergence should not
be constant. I have come up with a theory which supports constant divergence. I
do not know whether this is already known. If so I would like to hear about it.
    In most 'higher' species there vast amounts of junk DNA, sequences which have
no distinct impact on the specie. These sequences are not retained by selection
preassure, and therefore they will gradually erode. If we regard mutation rate as
constant, we can assume that the junk DNA erodes at a constant pace. Since the
amount of junk DNA is much, much larger than the amount of functional DNA, we
need not take the functional DNA into account. This means that the genetic clock
is an approximately linear function of time with a possible 5% inaccuracy. This 
will initially only work on comparisons of whole genomes (or large strings of DNA)
I will try to show that this is true also for the protein test, comparison of
proteins. 
    As we know, proteins reflects functional genes. Thus, we cannot rely on the 
steady decay of junk DNA since they do not affect the proteins. On the other hand
we know that many sequences are equivalent. It doesn't matter which is which.
They code the same acids. This also means that they are not a subject to
selective preassure and therefore the same conditions exist for these sequences
as for junk DNA. If species no longer interact (sexually) these sequences will
diverge. And because they are only a subject to mutations, which is constant,
they will diverge linearly. Hence linearity also applies to the proteins although
the uncertainty will be greater than in direct genome comparison.
     If someone has any comments, views or something to add, I would love to hear
it. I don't mind a debate so please write.

humans eat.  Note: look at dog food contents - Rice and Lamb, Corn Meal,
etc.  I am not saying that they are grazers like a cow or a horse or
that they seek out those foods.  

	I am not sure if a cow or a horse would even eat meat if it was
