The studies carried out by this group have proved the high protection these extracts can offer against anti-radicals as they are rich in carotenes and phycocyanins. Besides a considerable content of enzyme superoxide dismutase and vitamin E, elements which are part of the organism’s defensive system against radicals, they stimulate the immunological system and prevent cancer and rapid ageing.
Doctor Ivonne Almiral, main researcher of the project, asserts that this plant “has an antioxidant system which prevents the harmful action of radicals in dermis and epidermis”. After positioning in Cuban internal market and meeting populations needs, the new line of cosmetic products Shaman, produced with hydroalcoholic extracts of Cuban Spirulina platensis is opened to the international market. At present, the products of this line can be found in Bolivia, Ecuador, Dominican Republic and Peru and eventually there have been exports to countries such as Spain, Italy, France, Mexico and Martinique.
18 products, whose formulations happened to be physical, chemical and microbiologically stable and did not show skin or ophthalmologic irritability, form the complete line including a variety of creams (anti-rides, nutritive for dry skin, oily, for daily use, after sun, regenerative and softening), lotions (cleansing hydroalcoholic and cleansing alcohol-free), facial gel, hair revitalizer, rinsing facial tonic, masks (regenerative for dry skin, astringent, whitening, corporal), make-up remover, sun protection and massage body milk.
The benefits of Cuban Spirulina Planteses
At present, the aim of cosmetics is to preserve the high level of functionality of the skin, which is constantly exposed to different environmental influences and the loss of essential substances, a process that happens with the passing of years. Although the world of cosmetics is in full development, the present trend revolves around of cosmetics based on natural principles, regenerative and revitalizing substances extracted from nature. Treatments from algae and mud extracted from the sea, clay, extracts and flower essences, plants and fine wood.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
