Weekly Roundup: CBD, Love, Dolphins, and More

1. The Science Behind Falling in Love

What is love? Magdalena Osial takes a dive into the cocktail of chemical reactions that happen in the brain throughout the several phases of a relationship.

Usually, the attraction is associated with desire, a phenomenon intrinsically linked with the brain pathways that control “reward” behaviors. The hypothalamus produces dopamine that, when released, stimulates a good mood: a “reward” to our brains.

2. CBD Circulation In EU

The Court of Justice of the European Union (EU) decreed last Thursday,19th of November 2020, that cannabidiol (CBD) will not be considered a narcotic by the EU, recommending the member countries to allow its free circulation.

The definition of the term “drug”, or “narcotic drug”, by the EU relies on two distinct United Nations conventions: The Convention on Psychotropic Substances and the Single Convention on Narcotic Drugs.

CBD, however, is not mentioned in the former, and the Single Convention on Narcotic drug and, while it is true that a literal interpretation of the latter might lead to its being classified as a drug, in so far as it is a cannabis extract, such an interpretation would be contrary to the general spirit of that convention and to its objective of protecting ‘the health and welfare of mankind’.

While tetrahydrocannabinol (THC) —another hemp cannabinoid — may cause psychotic or harmful effects, the same does not appear to be true for CBD.

The court’s decision came after France banned, in 2014, the marketing and import of CBD, which is legally grown in other European Union countries.

About Cannabidiol (CBD)

The plant Cannabis sativa L. contains several cannabinoids, including tetrahydrocannabinol (THC) and cannabidiol (CBD).

Here is a list of available research of some of the therapeutic applications of CBD, including the treatment of colorectal cancer, anxiety disorders, leukemia, epilepsy, and more.

4. Dolphins can consciously slow their hearts

Dolphins actively control their heart rates before diving, to adjust pressure and oxygen before entering the water.

The findings, published in the journal Frontiers in Psychology last Tuesday, suggest that these marine animals alter their cardiac frequency to suit the length of their planned dive.

5. Scientists find Sars-Cov2 relatives in Japan and Cambodia

Two teams of researchers found coronaviruses closely related to Sars-CoV-2 in frozen bats in Cambodia and Japan. These are the first known relatives of Sars-CoV-2 to be found outside China and might give a clue on how the viruses jumped from bats to humans.

The viruses found in Cambodia and Japan were found in horseshoe bats captured in 2010 and 2013, respectively. Even though they may be too distant to account for the current pandemic, the discovery confirms that coronaviruses are relatively common in these bats, which seem to be frequent reservoirs of coronaviruses.

Other teams have already started to investigate other bats stored in freezers in Asian countries.
