- December 1, 2003: Updated information about the Brainstorming Week on Membrane Computing (BWMC 2004): The Brainstorming Week on Membrane Computing 2004, initially planned to be in Tarragona (Spain), will be hold in Sevilla, Spain. The dates are the same: from February 2, 2004 to February 7, 2004. See updated details in the Brainstorming Week Page.
- November 18, 2003: New directions and motivations in the area of Membrane Computing. A recent paper by C.S. Calude and Gh. Paun shows the theoretical possibility of computing functions beyond Turing machines using biologically computing agents. Such agents are expressend in terms of P Systems.
The paper can be downloaded at: http://www.cs.auckland.ac.nz/CDMTCS//researchreports/226cris.pdf
- October 15, 2003: P Systems Web Pages reached 10000 hits! On October 15, 2003, we have had the 10000th visit to the P Systems Web Pages. The counter started on January 15, 2001; hence, this visit has been done EXACTLY 33 months later. Almost half of the visits (4757) have been done since January 1, 2003!
- October 3, 2003: Membrane Computing selected as a fast Emerging Research Front. Membrane Computing has been selected by the Institute for Scientific Information, USA, as a fast "Emerging Research Front" in Computer Science, and the paper A. Paun, Gh. Paun, The power of communication: P systems with symport/antiport, New Generation Computing, 20, 3 (2002), 295-305, has been mentioned as a highly cited paper in the October 2003.

- September 1, 2003: Rovira i Virgili University, Research Group on Mathematical Linguistics (Tarragona, Spain) announces the 3nd International PhD school in formal languages and application
- July 17, 2003: The First P Prize was Awarded!
The first P prize announced since several years in the P page -- referring to a problem open since the beginnings of membrane computing -- was awarded during WMC 2003, Tarragona, July 17-22, 2003.
The prize asked for an infinite hierarchy on the number of membranes, for a class of P systems defined in a natural way (without restrictions which would "visibly enforce" the desired result). Partial solutions to this problem were previously given by R. Freund (Vienna, Austria) and S.N. Krishna (Madras, India), which however were based on definitions which were considered as too restrictive (hence not "completely innocent").
The solution considered as convincingly answering the problem is provided by O.H. Ibarra (Department of Computer Science,
University of California, Santa Barbara, CA, USA) in the paper "The Number of Membranes Matters". Actually, the paper provides several related infinite hierarchies on the number of membranes, for several classes of P systems with the computation based on communication. Details can be found in the pre-proceedings volume, available also through our web page.

- January 10, 2003: A message from the organizers of the First Joint International Meeting between the American Mathematical Society and the Real Sociedad Matematica Espanola:
"Dear Collegues, we would like to let you know that a Special Session on Biomolecular Mathematics will be held in the context of the First Joint International Meeting between the American Mathematical Society and the Real Sociedad Matematica Espanola (Sevilla, Spain, June 18-21, 2003). Please, visit http://www.rsme.es/
Confirmed invited speakers include: Alessandra Carbone, Rudolf Freund, Tero Harju, Gheorghe Paun and Rani Siromoney. A few more are still only tentative.
After refereeing, the programme of the Special Session will include also 20-30 minute contributions on topics in the scope of the event (broadly, connections between molecular biology and mathematical computer science).
The deadline for submission is February 10, 2003. See the details in the above-mentioned web page.
We would like to welcome you in Sevilla in June!
Tom Head, Fernando Guzman, Carlos Martin-Vide, Mario Perez-Jimenez"

- October 3, 2002: Hideaki Suzuki and Jian-Qin Liu of ATR (Advanced Telecommunications Research institute - Japan) are trying to organize a session titled "artificial chemistry", in AROB 2003: http://AROB.cc.oita-u.ac.jp/
One of the topic of the session is P-systems/membrane computing, because of it is one of the most important approach to study artificial life. The hope is that this session will be helpful for more people to study "P-systems/Membrane computing"
The homepage on the session can be fount at: http://www.his.atr.co.jp/~jqliu/AC03.html
which includes a tentative program of the session.
