Musician is probably one interesting and close analogy model of scientific researcher a real bridge between art and science.
A musician needs inspiration to compose some new or innovative melody or music that pleases a world community (not only a specific part of it), have to present a finished result/product, likely a plethora of songs to fill a CD-Rom (around minimum 30 minutes of music, sometimes even a complete symphony or opera). All the instruments used chords and rhythm have to be meticulously organized in perfect timing and harmony etc etc
During concerts, one might have to adapt in real-time to the public reaction and probably even some improvisation needed to come out of trouble.
Actually it is harder than scientific research in requirements of personal aptitudes.
Lets welcome musicians to science field, SO ALL THIS IS TO INVITE YOU TO WATCH

NeuroFeedback Training: Intensity analysis
Uso de Processadores Gráficos para Simulações baseadas em Agentes
Agent-based modelling is a programming and simulation paradigm. It is a bottom-up approach where
interacting agents are its basic building blocks. However, ABMs must undergo a process of independent implementation and verification to achieve credibility, where different replications of an ABM should provide similar
statistical results. Yet the reality is quite different and too often we observe many replications of a given model
presenting wildly different results. This may happen because ABMs are very sensitive to implementation details,
and the lack of a complete and formal model description often leaves researchers with the burden of creating
implementations based on personal interpretations of the model.
In this work we provide a complete description of the Heatbugs model based on its NetLogo implementation.
To accomplish this, we use the ODD protocol, which allows us to formalize the model so that future independent
replications are able to yield similar results. In addition, we provide results analysis for performance and
statistical alignment for two Heatbugs model replications: 1) a single threaded CPU implementation in C; and,
2) a parallel GPU implementation in OpenCL.
Molecular models of a protein’s structure can give detailed insight into mechanisms underlying its function, especially when viewed combined with sequence features.
In theory, 3D structural models are now available for many proteins, however in practice it is often complex to find all appropriate models and view them with sequence features. Thus it was developed Aquaria, a new web resource that provides 49 million pre-calculated structural models using homology from sequence to structure – 10 times more than currently available from other resources.
Using Aquaria we surveyed not only the visible proteome, but also the ‘unknown’ or ‘dark’ proteome, i.e., regions of proteins that remain stubbornly inaccessible to both experimental structure determination and modeling. Building upon a recent structural modeling study covering 546,000 proteins across many organisms, it was found 44–54% of the proteome in eukaryotes and viruses is dark, compared with only 14% for archaea and bacteria. Surprisingly, most dark proteins cannot be accounted for by (expected) conventional explanations, beside that the dark proteome has unexpected features.
Therefore, this work suggests several new directions for research in structural and computational biology. This work will help focus future research efforts to shed light on the remaining dark proteome.

Neuroengineering is a recently developed and rapidly changing domain in Biomedical Engineering that employs engineering methodologies to address the problems of “understanding, repairing, enhancing or otherwise exploring the properties of neural systems”. Its main goal is to develop tools to investigate the human brain and artificial devices to interact with it in order to repair and/or enhance its function, particularly through brain-computer interfaces and neuroprosthetics.
Neuroengineering draws on disciplines ranging from Neuroscience to Biophysics, Electrical Engineering, Computer Science, Materials Science, and Tissue Engineering. Faculty with relevant and complementary expertise in engineering within IST (mostly DBE, but also DEEC and DEI) will join with neuroscience faculty from CNP and FMUL, in order to provide a course on Neuroengineering.
The main objective of the course is to provide students with comprehensive background knowledge of the most important areas in the field of Neuroengineering, including the existing challenges and the main concepts and techniques that can be used to address them.
Students successfully completing the course are expected to: 1) have basic knowledge about the organization, structure, function and pathological modifications of neural systems; 2) have general knowledge about the principles, methodologies and applications of the main engineering techniques used to study and interact with neural systems, with the objectives of brain monitoring, diagnosing, modulating, repairing, enhancing or interfacing with machines; and 3) be prepared to critically evaluate different problems and techniques in Neuroengineering.
The course will be organized as a series of teaching modules addressing a number of specific topics in Neuroengineering, primarily aimed at students with a background in engineering (1st cycle / BSc in engineering). Each module will last 1-2 weeks, and will be organized by an expert in the field.
The course will take a multidisciplinary approach, targeting state-of-the-art techniques, and it will include conventional lectures as well as seminars by invited experts and journal club classes for the discussion of relevant scientific literature.

The "dark proteome"—protein regions whose structures are completely unknown—is a key remaining frontier in our understanding of biological systems. A new study now shows that roughly half of the proteome in eukaryotes and viruses is dark, highlighting the need for more sensitive tools to explore the full expanse of the protein universe.
Despite tremendous progress in characterizing the protein universe, many proteins reside in the dark proteome since they have regions of unknown structure. Exploring the dark proteome could clarify future research directions as studies of dark matter have done in physics. After all, this analogy has inspired surveys of other unknown protein properties, such as the “dark matter of the protein universe”—orphan protein sequences that do not match any known sequence profiles.
The Systems Biology of Cancer group investigates the circadian regulation of tumour-driving mechanisms. The group includes both dry lab facilities at the Institute for Theoretical Biology and wet lab facilities at the Molecular Cancer Research Centre. We work together with bioinformaticians, physicists, molecular biologists and medical doctors and closely collaborate with the European Molecular Biology Laboratory (EMBL) where the group members are encouraged to attend conferences and courses.
Our group uses a systems biology approach involving wet-lab experiments, genome wide screening of gene expression of human and murine cells, bioinformatics and computational models, to understand the dynamic interplay between cancer and the circadian clock. With such a methodology, we aim to investigate the pathways which connect the circadian clock to cancer regulation at the transcriptional (including splicing) and translational levels.
