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 pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
