Crisi global i ecologia
Des que es va fer públic el problema de les hipoteques d'alt risc als EUA, els analistes adverteixen de la possibilitat d'una recessió econòmica, la qual es comença a fer evident en el descens en les vendes d'automòbils, ...
Lower incisor dentoalveolar compensation and symphysis dimensions among Class I and III malocclusion patients with different facial vertical skeletal patterns
Objective: To compare lower incisor dentoalveolar compensation and mandible symphysis morphology among Class I and Class III malocclusion patients with different facial vertical skeletal patterns. Materials and Methods: ...
Conserved developmental expression of Fezf in chordates and Drosophila and the origin of the Zona Limitans Intrathalamica (ZLI) brain organizer
Background: The zona limitans intrathalamica (ZLI) and the isthmus organizer (IsO) are two major secondary organizers of vertebrate brain development. These organizers are located at the interface of the expression domains ...
Autophagy in Tissue Repair and Regeneration
Autophagy is a cellular recycling system that, through the sequestration and degradation of intracellular components regulates multiple cellular functions to maintain cellular homeostasis and survival. Dysregulation of ...
Gene flow and gene flux shape evolutionary patterns of variation in Drosophila subobscura
Gene flow (defined as allele exchange between populations) and gene flux (defined as allele exchange during meiosis in heterokaryotypic females) are important factors decreasing genetic differentiation between populations ...
Camins químics de la ment
A l'article 'Cranis,cervells i formigues' vaig parlar de l'increment de les capacitats cognitives en el nostre llinatge, i vaig dir que cal recórrer a l'estructura del propi cervell, al nombre de connexions neurals i a la ...
Comparison of mouse and human genomes followed by experimental verification yields an estimated 1,019 additional genes.
A primary motivation for sequencing the mouse genome was to accelerate the discovery of mammalian genes by using sequence conservation between mouse and human to identify coding exons. Achieving this goal proved challenging ...
A new cerkl mouse model generated by CRISPR-Cas9 shows progressive retinal degeneration and altered morphological and electrophysiological phenotype
Purpose: Close to 100 genes cause retinitis pigmentosa, a Mendelian rare disease that affects 1 out of 4000 people worldwide. Mutations in the ceramide kinase-like gene (CERKL) are a prevalent cause of autosomal recessive ...
L'excés de motivació perjudica la presa de decisions
Cada dia prenem centenars de petites decisions. La major part de vegades sense ser-ne del tot conscients, guiats per les nostres necessitats internes i per les condicions de l'entorn, que inclouen les interaccions amb ...
Tai-txi per organitzar el cervell
Aging Neuroscience acaba de publicar un treball d"un equip de recerca de l"Acadèmia de Ciències Xineses i de la Universitat de Pequín encapçalat per Xi-Nian Zuo, director del laboratori de connectòmica funcional<br>la ...
STEM on estem
L'any 2015, la Comissió Europea va engegar el projecte Hypatia, que manlleva el nom de la filòsofa, astrònoma i matemàtica grega de finals del segle IV. L'objectiu és afavorir l'acostament de les nenes i les noies a les ...
Introduced Drosophila subobscura populations perform better than native populations during an oviposition choice task due to increased fecundity but similar learning ability
The success of invasive species is tightly linked to their fitness in a putatively novel environment. While quantitative components of fitness have been studied extensively in the context of invasive species, fewer studies ...
L'educació bull
Un dels pilars fonamentals de la societat és l'educació. Fa temps que ens trobem en un impàs educatiu, la qual cosa em preocupa personalment i professionalment, com a coordinador de biologia del Consell Interuniversitari ...
The Ediacaran Origin of Ecdysozoa: Integrating Fossil and Phylogenomic Data
Ecdysozoans (Phyla Arthropoda, Kinorhyncha, Loricifera, Nematoda, Nematomorpha, Onychophora, Priapulida, Tardigrada) are invertebrates bearing a tough, periodically moulted cuticle that predisposes them to exceptional ...
Física, ciència i pseudociència
Una de les característiques destacades de l'intel·lecte humà és la tendència innata que tenim a voler explicar el món que ens envolta i a buscar motius i causes a tot el que succeeix. Aquest principi, que és ben present ...
Sustainable natural bioresources in crop protection: antimicrobial hydroxycoumarins induce membrane depolarization-associated changes in the transcriptome of Ralstonia solanacearum
Background: Ralstonia solanacearum is one of the most devastating pathogens affecting crop production worldwide. The hydroxycoumarins (umbelliferone, esculetin and daphnetin) represent sustainable natural bioresources on ...
Chromosomal polymorphism of D. subobscura: no differences between wild males and sons of wild females
When analyzing the chromosomal polymorphism of D. subobscura natural populations it is assumed that the information provided by wild males and sons of wild females is equivalent. Thus, using both in the analysis it is ...
Transcriptomic analysis of Planarians under simulated microgravity or 8g demonstrates that alteration of gravity induces genomic and cellular alterations that could facilitate tumoral transformation
The possibility of humans to live outside of Earth on another planet has attracted the attention of numerous scientists around the world. One of the greatest difficulties is that humans cannot live in an extra-Earth ...
El virus de Nietzsche
Un dels temes més recurrents a la premsa aquestes darreres setmanes, a part de l'estranya epidèmia que ha generat el nou Estatut i de la contagiosa espiral de violència a França, és sens dubte la gripe aviària i la ...
Les arrels del cervell
La nostra història és fascinant. No em refereixo només a la trajectòria vital de cadascú, perquè totes ho són. Ni tampoc als fets històrics que ens han conduït on som, el coneixent dels quals és indispensable per gestionar ...
