Moths and butterflies are known to complete their diet by drinking the tears of reptiles and birds thanks to the elongated appendage that serves as their mouthpart. But it is not necessary to have such a proboscis to become a “tear drinker”.
The researcher from Madrid had worked in video games and fashion before the Bill & Melinda Gates Foundation signed her up. Her experiences in machine learning and behavioral prediction models will help to improve the learning apps used by midwives in resource-poor countries. The goal is to reduce maternal and infant deaths during pregnancy and childbirth.
When it was discovered in the 1980s in Argentina, this hadrosaur was diagnosed with a fractured foot. However, a new analysis now shows that this ornithopod commonly known as the duck-billed dinosaur actually had a tumour some 70 million years ago, as well as two painful fractures in the vertebrae of its tail, despite which, it managed to survive for some time.
Last December, the Parliament of Catalonia unanimously approved the incorporation into its legislation of second-order violence against those who give their support to victims of violence against women. A recent study compiles testimonies of victims, and analyses this form of intimidation.
Diagnostic imaging equipment has improved the resolution of its results and reduced the radiation patients receive, but the main advance has been in contrast agents. Using dye- or nano-antibody-‘decorated’ nanoparticles that circulate in the blood vessels, the scientific community is working to detect cancer and metastasis early and see if the treatment works.
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.
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.
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.
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.
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.
