Sistemul UE pentru urmărirea comercializării produselor din tutun a devenit operaţional
"Sistemul european pentru urmărirea comercializării produselor din tutun, care include elemente de siguranţă, a devenit operaţional astăzi. Primii producători din Uniunea Europeană au solicitat şi au primit mărci de urmărire a ţigărilor şi produselor artizanale. Consumatorii vor observa în curând mărci de localizare pe pachete, precum şi elemente de siguranţă", a anunţat luni Comisia Europeană.
Chemicals that leach out of plastic rubbish were found to impair the growth of bacteria in the ocean responsible for producing a large volume of the oxygen in our atmosphere(Credit: ead72/Depositphotos)
An important new study is raising novel concerns over the effects of plastic pollution in our oceans. For the first time researchers investigated how a common ocean bacteria, responsible for producing over 10 percent of oxygen in the atmosphere, is negatively impaired by chemicals that can leach out of plastic products.
Prochlorococcus is a tiny cyanobacterial genus that was only discovered a little over 30 years ago. This remarkable cyanobacterium is not only the smallest photosynthesizing organism on the planet, but also one of the most abundant. Some estimates suggest there are as much as three octillion Prochlorococcus in the ocean, where they not only help keep the waters healthy, but also produce a substantial volume of the oxygen we breathe.
The Lilium Jet five-seat aircraft on its maiden flight(Credit: Lilium)
Lilium first emerged in 2016 as an aviation startup with some very lofty ambitions, revealing plans to develop a five-seat electric aircraft that can take off vertically, switch to horizontal flight in mid-air and cover some sizable distances on each charge. The company has now taken a significant step toward achieving this goal, completing a flight of a full-scale prototype of its Lilium Jet for the very first time.
A noble plan to improve housing access for those in need through cutting-edge construction technology is gathering momentum, with a blueprint now in place for what is billed as the world's first 3D-printed community. Set to take shape in Latin America, the cluster of homes is designed for families living on less than US$200 a month, and will ideally serve as proof of concept for low-cost housing solutions around the world.

Evolution is an amazing process, helping life adapt to new environments and conditions – and now scientists have uncovered a rare occasion where it got a second chance. About 136,000 years ago, a flightless bird on an island in the Indian Ocean was wiped out, only to re-evolve itself back into existence tens of thousands of years later.
Species are shaped by environmental pressures, which can make evolution a predictable process at times. It's not entirely surprising that sometimes after a species dies off, a new species with some very similar characteristics might arise in the same location later on. After all, evolution is basically following a recipe – if you put similar ingredients through the same process, the end result should be similar the second time around. This reoccurrence is known as iterative evolution.
