Scientists warn: Humanity does not have effective tools to resist the tsunami

Based on the carried out analysis, the world s leading experts on natural hazards have outlined directions for further scientific research. The research group s review is published in a special issue of the Frontiers in Earth Science . The main problems identified in the review are related to the large gaps and uncertainties in knowledge about tsunami, the lack of well-documented observations, and imperfect methods of processing available information. One of the reasons is the lack of coordination of the efforts of those countries for which the study and prediction of tsunam

Researchers review materials used to design biosensors for SARS-CoV-2 detection

Researchers review materials used to design biosensors for SARS-CoV-2 detection The SARS-CoV-2 virus is still causing a dramatic loss of human lives worldwide, constituting an unprecedented challenge for society, public health, and economy, to overcome. Currently, SARS-CoV-2 can be diagnosed in two different ways: i) antigen tests (point-of-care, POC) and ii) molecular tests (nucleic acid, RNA, or PCR-polymerase chain reaction). Antigen tests can detect parts of SARS-CoV-2 proteins, known as antigens, via a nasopharyngeal or nasal swab sampling method. The main advantages of POC-test include the high specificity, quick response (less than an hour), and portability, with no need of fixed laboratory facilities.

On the other hand, in a molecular diagnostic test, a reverse transcriptase polymerase chain reaction (RT-PCR) is evolved, also known as nucleic acid amplification method,
