Any drone must be traceable and identifiable by radio in the U.S.

All civilian drones except the smaller ones (basically toy drones for a few euros) should transmit their location data by radio to ensure that the identity of the drone and of the owner/operator is always available, a sort of “air” plate as well as vehicle plates.

This is the purpose of the US Federal Aviation Administration which wants to create in the United States what is already seen as a huge new tracking network for anything that can take flight and is equipped with a moped. The measure, which has not yet entered into force, has already sparked numerous comments from the American public, so much so that it is thought that it will still be subject to change.

The American institutions themselves, however, believe that this measure is essential not only for security but also to advance the drone-driven trade that is becoming increasingly widespread, particularly in the delivery of consumer goods. That of the recognition in flight will prove to be “a fundamental element in the ecosystem of unmanned traffic management”, report the top management of the agency according to which all drones weighing more than 0.25 kg will be required to transmit their position and the identity of the operator at any time by radio, a bit like air traffic with traditional aircraft.

Data transmission will have to take place on a specific radio frequency which can be monitored 24 hours a day. The same data could then also be transmitted via the Internet. In this way, any police force, naturally equipped with the necessary tracking devices, will be able to identify the drone and the operator flying it at any time.

The main obstacle is, of course, the fact that all existing drones will have to install a new tracking device or else they will be banned from flying something that would inevitably increase the costs of new drones entering the market.

A new viable embryo from a northern white rhino has been created

Another embryo of northern white rhino, an almost extinct animal, was created by a team of researchers. The animal is in fact very close to extinction as only two female specimens remain. The embryo was created with eggs taken from the females and inseminated with semen that had previously been frozen by male specimens then dead.

These embryos, preserved in liquid nitrogen, can then be inserted into the body of a surrogate mother and this is what the researchers are going to do over the next few months.

This was noted in a statement by the Associated Press with an intervention by Kenya’s wildlife minister, Najib Balala, who reveals that the long-term goal of the project is to give birth to at least five more specimens of the northern white rhinoceros so that they can be inserted into their natural African habitat. Of course, this is a project that could take many years, perhaps decades.

At the moment only two females, called Najin and Fatu, are still alive in a park in Kenya. The embryos were taken from Fatu himself.

Now all that remains is to select females of southern white rhinos that can act as surrogate mothers, another not easy thing because even the latter are not very easy to find because of poaching (the animals are killed for their precious horns used to make carving objects but also for practices not better identified in traditional Chinese medicine).
