Top Science News of the Year – A Salmonella Epidemic Could Contribute to the Collapse of the Aztec Empire


The year is defined as the period of time that elapses during a real revolution of the Earth’s axis in its orbit around the Sun.

It is this cyclical phenomenon that humans use to temporarily orient ourselves, and our entire life is distributed and planned around grouped periods of 12 months.

For this reason, it is usual that, at the end of a new year, we want to collect and analyze everything we have experienced, to assess whether, indeed, we are succeeding in life as humans.

Exactly the same thing happens in science. Here, what we evaluate are thevery relevant findings and events left by science and technology throughout the year.

If we take stock,2018 has been an especially prolific year in advancements in the field of astronomy.Not only have we prospered in the exploration of the neighboring planet Mars, but we have also deepened our knowledge of other bodies in the Solar System, even in the earliest history of the formation of our cosmic neighborhood; and also, beyond him.

The findings in biomedicine also stand out, withpromising results to address treatmentof the dreaded group of diseases that is cancer. And we have also explored in our own past as a species, tofind out more about our ancestors: who they were, where they came from and what happened to them.

Unfortunately, among the events stands out very bad news for science: the death of Stephen Hawking, the most important theoretical physicist since Albert Einstein, who gave us unrivaled knowledge about black holes; and he tried tirelessly to reconcile the Theory of Relativity and Quantum Physics to achieve the desired ‘Theory of Everything’.

For a scientific investigation to see the light, it must first go through a sophisticated process of correction and revision. Since a group of researchers raises a study until it sees the light in one of the prestigious scientific journals that publish them (Nature, Science, PNAS …), years go by.

And although the process of creating, developing or observing science is beautiful in itself, the fundamental thing is that what happened reaches the ears of the global population. Not only to learn and get rich, but as a fundamental right: the right to information.

Information is power, and it allows us to be free and to decide. Hence the beauty of disclosure. In this gallery, we review the most important scientific news that 2018 has left us, so that you can inform yourself, assess for yourself, andlead all the conversations this holiday season on science, technology and biomedicine.

Slaves and Disabled: Forced Medical Test Volunteers

The main problem to carry out medical research is to have willing volunteers for it. And if they come out for free, much better. This is the story of unethical behavior in medical research.
