  • Scientists have discovered three new species of flying reptiles that lived in the Sahara 100m years ago.
  • The study has revealed a community of pterosaurs that inhabited prehistoric Morocco. The findings show that African pterosaurs were quite similar to those found on other continents.
  • The new pterosaurs, identified from chunks of jaws and teeth found in the middle cretaceous Kem Kem beds of Morocco, had wingspans of three to four metres.

Scientists store quantum information in diamond

Date: 30 March 2020 Tags: Fourth Industrial Revolution
  • A team of researchers has managed to build a data note that can decrease the distanced traversed by quantum data by half. This advanced system has to be kept at a temperature of absolute zero or zero degrees Kelvin.
  • It involves the use of a modified diamond, with two of the carbon diamonds being replaced with a single silicon atom. The alteration creates an area where a quantum state can be stored for a limited amount of time.
  • The system can receive and store quantum states from two different sources, and a synchronization process will lead to the appearance of a secure key which can be used to decrypt and encrypt the messages between the two sources in a safe manner.

Ban on hairspray helps ozone layer to recover

  • A large hole in the ozone layer is continuing to heal, helping weather systems in the southern hemisphere to go back to normal, according to a study.
  • Prolific use of the chemicals chlorofluorocarbons, or CFCs, caused incredible damage to the ozone after they became widespread in the 1960s. As well as being used industrially for refrigeration and the manufacture of packaging materials, they were also in household aerosols like hairspray and in air conditioning units.
  • While relatively harmless when released in our lower atmosphere, they undergo a reaction when they are hit by sunlight in the stratosphere. The chlorine these chemicals release destroys the ozone layer, a protective cocoon of gas that shields us from harmful solar radiation.
