Shō-coin: A knowledge-based economy for Life Sciences

Alexander Garcia, Erick Antezana, Jael Garcia, Olga Giraldo, Pjotr Prins & Rutger Vos
With the continuous creation, sharing and transformation of data re-sulting from Research and Development in the Life Sciences domain, provenance tracking and valorization of research outputs remain challenges. Tracing biomed-ical materials and associated data throughout the research life cycle requires tracking materials, methods, transformations, partial results, locations and many other facets. Research is not always carried out in one place; it is usually distrib-uted across several laboratories. Accordingly, research outcomes of various kinds are constantly...

Brief Solutions to Collatz Problem, Goldbach Conjecture and Twin Primes

Mesut Kavak
I published some solutions a time ago to Goldbach Conjecture, Collatz Problem and Twin Primes; but I noticed that there were some serious logic voids to explain the problems. After that I made some corrections in my another article; but still there were some mistakes. Even so, I can say it easily that here I brought exact solutions for them out by new methods back to the drawing board.

A look to the sustainable draining systems: Criteria of sustainability and successful cases

Sandra Sánchez-Sabau, Marian Sabau, Linda Montero, Jorge González-Coneo, Ana Abellàn & Camilo Osorio
There have been many studies and research that address sustainable drainage urban systems (SUDS), where factors like costs or the zone where a SUDS is to be installed are determinant, so multicriteria studies are important in decision-making. The development of a multidisciplinary approach could in the future serve as a helping tool to support decision, whose purpose would be to guide users in their choice of the most appropriate solution for managing the collection of...

The P = NP Answer

Frank Vega
P versus NP is considered as one of the most important open problems in computer science. This consists in knowing the answer of the following question: Is P equal to NP? This question was first mentioned in a letter written by John Nash to the National Security Agency in 1955. A precise statement of the P versus NP problem was introduced independently in 1971 by Stephen Cook and Leonid Levin. Since that date, all efforts...

The E3 ubiquitin ligase NEDD4 enhances killing of membrane-perturbing intracellular bacteria by promoting autophagy

Gang Pei, Hellen Buijze, Haipeng Liu, Pedro Moura-Alves, Christian Goosmann, Volker Brinkmann, Hiroshi Kawabe, Anca Dorhoi & Stefan H. E. Kaufmann
The E3 ubiquitin ligase NEDD4 has been intensively studied in processes involved in viral infections, such as virus budding. However, little is known about its functions in bacterial infections. Our investigations into the role of NEDD4 in intracellular bacterial infections demonstrate that Mycobacterium tuberculosis and Listeria monocytogenes, but not Mycobacterium bovis BCG, replicate more efficiently in NEDD4 knockdown macrophages. In parallel, NEDD4 knockdown or knockout impaired basal macroautophagy/autophagy, as well as infection-induced autophagy. Conversely, NEDD4...

Regulation of glycolytic metabolism by autophagy in liver cancer involves selective autophagic degradation of HK2 (hexokinase 2)

Lin Jiao, Hai-Liang Zhang, Dan-Dan Li, Ke-Li Yang, Jun Tang, Xuan Li, Jiao Ji, Yan Yu, Rui-Yan Wu, Senthilkumar Ravichandran, Jian-Jun Liu, Gong-Kan Feng, Min-Shan Chen, Yi-Xin Zeng, Rong Deng & Xiao-Feng Zhu
Impaired macroautophagy/autophagy and high levels of glycolysis are prevalent in liver cancer. However, it remains unknown whether there is a regulatory relationship between autophagy and glycolytic metabolism. In this study, by utilizing cancer cells with basal or impaired autophagic flux, we demonstrated that glycolytic activity is negatively correlated with autophagy level. The autophagic degradation of HK2 (hexokinase 2), a crucial glycolytic enzyme catalyzing the conversion of glucose to glucose-6-phosphate, was found to be involved in...

How palynology could have been paepalology: the naming of a discipline

Kevin J. Edwards & Heather S. Pardoe
From its ‘modern’ pollen-analytical beginnings, the science of what we now term palynology wrestled with terminology and sought an acceptable name for the discipline. Starting in 1943, the mimeographed Pollen Analysis Circular, edited from Ohio by Paul Sears, led to discussion of the content, organisation and naming of a developing discipline. This came to a head in 1944 with Ernst Antev's plea for ‘The Right Word’ and the suggestion of the word ‘palynology’ from the...
