Using such knowledge and maslinic acid isolation from olive remains by scientists of the Department of Organic Chemistry of the UGR [http://www.ugr.es], they started to do research into the growth possibilities of this compound, which works as a serin protease inhibitor, for fishes like rainbow trouts. Results are clear: fishes whose diets are complemented with maslinic acid grow bigger and sooner, and fewer of them die. It has been observed that these animals live better, that their scales and fins look better and that the normal death rate in fish farms, between 5 and 10%, reduces almost to zero.
Despite a lot of additives work as toxins in some species, maslinic acid has worked quite the opposite in rainbow trouts. Cells of these animals get better structured if they are supplied with this compound; its application in animal feeding is already waiting for its patent at international level.
Experiments have gone on for 225 days in 3 consecutive years to observe the growth process of fishes. In all, between three thousand and five hundred and four thousand animals have been studied, with an initial weight of 20 grams, especially brought from the fish farm for the study. Its growth and development is observed in five experimental groups, which are supplied with five types of doses: 1, 5, 25, 50, 100 and 250 miligrams for each kilogram of diet.
Fight against AIDS
Maslinic acid is a pentacyclic terpenic with antioxidant and anti-cancer effects which could have possitive consequences in the fight against AIDS; they are being studied in the Institute Carlos III under the supervision of Professor Vallejo Nájera. Currently, the group of Professor Lupiáñez Cara is working on anti-cancer effects of maslinic acid. To this end, it is necessary to go deeply into pharmacodynamic research, and into the selective capacity of this compound to inhibit cell apoptosis, this is, interruption of the planned cell death that caused by cancer.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
