<p>Research conducted by scientists and published in Nature Communications last November showed that earwax whales during her life revealed levels of cortisol that she produced. The results showed that whales were producing higher levels of cortisol during the years when whaling began (in the early 1900s and 1960s, and during the Second World War because of submarines and battleships).</p>

Landing the InSight vehicle on Mars

Mars surface

The fall of the InSight on Mars last month is one of the most important scientific events of the year. The task of the vehicle is limited to studying the seismic activity of Mars, which will allow scientists to understand the thickness of the crust of the planet and its size and temperature.

Clean the Pacific from garbage

Cleaning the ocean

The Dutch non-profit organization The Ocean Cleanup has launched its project to clean the ocean of plastic garbage. Although the project is still in the testing phase, it aims to collect plastic pieces through a U-shaped tool and discard them before they are broken by the sun in the sea and become harmful to marine life.

The number of animals shrank dramatically

Shrinking animals

According to the WWF Living Planet report of 2018, the average number of vertebrate groups declined by 60% between 1970 and 2014. Many species of animals have been extinct over the past 100 years due to overfishing and excessive fishing.

<p>Mountain gorillas, an endangered species of the International Union for the Conservation of Nature (IUCN), are growing in places where they live in the Democratic Republic of the Congo, Rwanda and Uganda. Thanks to government efforts and animal veterinary care.</p>

Although we feel alienated towards insects, their disappearance from the planet will be catastrophic! A study published in the Proceedings of the National Academy of Sciences has revealed that the biomass of arthropods, including insects and spiders, is decreasing by as much as 60 times in the rainforest of Puerto Rico and large parts of the world.

Discovery of evidence of a ninth planet in the solar system

Sun Group

In 2015, scientists identified an object called TG387 moving in an unusual elliptic orbit around the sun. Many evidence points to the presence of a huge invisible mass orbiting the sun, and scientists continue to look for facts to make sure the ninth planet is in the solar system.

Design of the first DNA

Nucleic acid

Chinese scientist He Jiankui said he used a gene-editing technology called CRISPR to change the DNA of two embryos and then implanted them into the mother's womb. The world claimed that the two children were born in good health.

However, scientists from around the world have been alarmed by this announcement as inaccurate and can not be used on human embryos as they are still in the process of being studied. This process also requires strict control to be tested in order to reduce serious, non-treatable genetic diseases.
