Cocodrilo
African crocodiles lived in Spain six million years ago
15 October 2020 8:00
Adeline Marcos

The crocodiles that inhabited the coasts of North Africa during the late Miocene period embarked on a journey to Europe across what is now the Mediterranean basin. This is confirmed by the analysis of the first fossils of the Crocodylus genus in the Iberian Peninsula, found in the Valencian site of Venta del Moro between 1995 and 2006, and which are now being described for the first time.

Climate crisis ages fish, amphibians and reptiles
16 September 2020 10:00
Adeline Marcos

Climatic conditions are changing at an unprecedented rate, affecting mainly fish, amphibians and reptiles, ectothermic animals that are unable to generate their own internal heat. With heat waves and rising temperatures, these organisms experience not only increased growth rates and heat stress, but also further ageing.

ANALYSIS
History repeats itself with the price of remdesivir

Vanessa López

The pharmaceutical company Gilead has announced that the price of their antiviral, used with modest results to treat COVID-19, will be 2083 Euros per patient when the minimum cost of production is 0.83 Euros per dose. The price of medicines should be related to the cost of development and production, plus a fair and reasonable profit, particularly in light of the public effort that has been invested in the R&D chain.

Shrimp shells to produce electrodes for large storage batteries

Spanish researchers at MIT have developed a system to produce electrodes for vanadium flow batteries, used in renewable energy storage. The electrodes are made from chitin, a polysaccharide found in the exoskeleton of crustaceans and insects. The advantage of this component is that it contains nitrogen in addition to carbon, which is then incorporated into the structure of the electron during the production process, improving electrode’s performance.

Insecto
The climate crisis threatens insects more than previously thought
1 June 2020 13:01
Adeline Marcos

Until now, insects in the tropics seemed to be the most threatened by climate change by living at the limit of their optimal temperature. An international team of scientists, with Spanish participation, has analysed the existing data and concluded that insects from temperate areas, such as Spain, could be as vulnerable to temperature increases as tropical insects.

Unraveling the magnetism of a graphene triangular flake
12 May 2020 12:07
SINC

Spanish scientists have detected for the first time the magnetic state of a triangular structure of graphene with just 40 carbon atoms. The finding expands the possible applications of this material in information technology.

Nanoparticles with quantum dots for restoring monuments
28 April 2020 11:31
SINC

The fluorescence emitted by tiny zinc oxide quantum dots can be used to determine the penetration depth of certain substances used in the restoration of historical buildings. Researchers from Pablo de Olavide University have tested this with samples collected from historical quarries in Cadiz, where the stone was used to build the city hall and cathedral of Seville.

Homeopathy relies on false scientific appearances to convince its users
16 April 2020 13:22
María G. Dionis

According to a study by two researchers from the Autonomous University of Madrid, one of the main reasons for people’s trust in alternative therapies is that the general public does not distinguish them from science. Consumers of homeopathy and acupuncture tend to be women with a medium-high socioeconomic level and higher education.

3D models of mountain lakes with a portable sonar and airborne laser
30 March 2020 8:40
Enrique Sacristán

The information of the territory provided by the laser technology from an airplane can be combined with data collected in mountain lakes with an inflatable boat and a small echo sounder to obtain three-dimensional maps. The system has been successfully tested by two geologists at the Truchillas glacial lake in Spain.

Los datos de la herida recogidos por el parche de grafeno se envían al hospital a través del móvil
Graphene for remote wound monitoring
23 March 2020 8:39
SINC

French scientists at the Neel Institute have produced a graphene patch that records the condition of chronic wounds, such as ulcers suffered by the elderly or those with diabetes, at any time. The data can be sent from home to the hospital via mobile phone, facilitating a rapid response to possible infections.
