# s-phyto-behav: Pea (Pisum sativum), a gambler plant

<< pea plants can demonstrate sensitivity to risk - namely, that they can make adaptive choices that take into account environmental variance, an ability previously unknown outside the animal kingdom >>

<< Alex Kacelnik (..) said: "To our knowledge, this is the first demonstration of an adaptive response to risk in an organism without a nervous system. We do not conclude that plants are intelligent in the sense used for humans or other animals, but rather that complex and interesting behaviours can theoretically be predicted as biological adaptations - and executed by organisms - on the basis of processes evolved to exploit natural opportunities efficiently >>

# s-phys: if you take a large collection of chaotic balls ...

<< If  you  take  a  large  collection  of  balls  in  contact  and  force  some  of  them  to  spin,  they  can  behave  like a  set  of  gears,  with  each  ball  rotating  without  slipping.  Experiments  and  theory  show  that  this synchronized  motion  can  be predicted  even  when the initial  motion  involves  seemingly  random slipping  between  the  spheres  (like  the  skipping  of  gears).  The  researchers  say  that  the  ability  to predict  this  collective  motion  could  lead  to  three-dimensional  gear  systems  in  which  manipulations of  one or two spheres allows complete control  of  the  rotational  motion  of  the  others >>

# s-behav: the intriguing behavior of the elderly Barbary macaques.

<< With  increasing  age,  the  monkeys [Barbary macaques (Macaca sylvanus)] became  more  selective  in  their  social  interactions,"  Almeling  says. "They  had  fewer  'friends'  and  invested  less  in  social  interactions.  Interestingly,  however,  they  were  still interested  in  what  was  going  on  in  their  social  world." >>
