The only way to finish college
It is always a humbling experience to compare our progress in technology with what nature has been doing for decades on end.
1-2 –> Iris in camera vs human eye
3-4 –> Iris mechanism in camera vs human eye
5-6 –> Accommodation of the eye
Have a good one!
“In 2020, two next-generation rovers will launch: ESA’s ExoMars and NASA’s Mars 2020. Instead of indirect inferences and possibilities, we’ll actually be able to understand whether the origin of these molecules is geological or biological in nature. It’s important to keep an open mind and let science, rather than our hopes or fears, decide the answer. The evidence is building, and we’re finally gaining a more robust picture of how, exactly, Mars works.
It’s producing methane seasonally, contains loads of carbon-based compounds, and had a very watery past. But does that all add up to life, past or present? In 2018, the evidence doesn’t say “yes” just yet. But in just a few years, we just might have the answer. In a few years, for the first time, we might finally know if there’s life beyond Earth.”
We use the word “organics” a lot when we talk about life (and molecules) beyond Earth. But while that word may conjure up images of reproducing molecules, new cells, and life, the scientific definition is far more mundane: a molecule containing carbon. That means carbon monoxide and cyanide are organic, even though they may be toxic to life itself. The discovery of seasonally-varying methane on Mars is interesting, but it may be better evidence for something geologically compelling than it is for anything biological. Regardless of how you interpret it, one thing is for certain: everything we’ve found on Mars so far is not yet enough to claim evidence for life.
“Although it’s just conjecture at this point, scientists speculate that life in the Universe is probably common, with the ingredients and opportunities for it to arise appearing practically everywhere. Life that thrives and sustains itself on a world, to the point where it can change its atmospheric and/or surface properties, may need to get lucky, and is likely more uncommon. Evolving to become complex, differentiated, multicellular creatures is likely even rarer. And as far as becoming what we would consider an intelligent, technologically advanced civilization, it could be so exceedingly remarkable that in all the Universe, it might just be us. Yet despite how different these outcomes are, we’re actively searching for all three types of life in very different ways. When the first sign of alien life finally is discovered, which one shall emerge victorious?
No matter which method pays dividends first, it will be among the greatest day in the history of life on Earth.”
There are three very different ways humanity is searching for alien life beyond Earth. We can directly search the various planets and moons in our Solar System for past or present biological signatures simply by sending decontaminated probes, and looking for the evidence in situ. We can indirectly look at distant worlds around other stars, searching for the characteristic changes to the atmosphere and surface that life would bring. And, most optimistically, we can search for intelligent signatures created, perhaps willfully, by a technologically advanced alien species.
“MERS-CoV (Middle- East Respiratory Syndrome Coronavirus) is a Coronavirus, endemic in Middle East. The virus attacks the human respiratory system and is considered to be highly pathogenic, causing a series of non-specific symptoms which complicate the diagnosis. It is transmitted through human-to-human contact, as well as through direct or indirect contact with host animals. The Wolrd Health Organization has declared MERS-CoV as one of the most likely to cause a future epidemic and urges for further research. It is worth mentioning that the mortality rate of humans infected by MERS-CoV is above 35%.
Since 2012, there have been reported cases of MERS-CoV infection in 27 countries, including Greece. The majority of cases were located in Saudi Arabia. However, the issue does not concern only the Middle East but the entire world as well. Modern means of transport eliminate distances, thus facilitating the movement both of humans and pathogenic microorganisms. Our test will be of great use to international travellers, so as to avoid outbreaks of the virus in regions were it isn’t endemic.”
