¦ ŞTIINŢĂ ŞI TEHNOLOGIE:

1. Hubble uncovers the brightest quasar in the early Universe
[Less than a billion years after the big bang, a monster black hole began devouring anything within its gravitational grasp. This triggered a firestorm of star formation around the black hole. A galaxy was being born. A blowtorch of energy, equivalent to the light from 600 trillion Suns, blazed across the universe. Now, 12.8 billion years later, the Hubble Space Telescope captured the beacon from this event.]

2. Internauţii vârstnici, mai înclinaţi să distribuie informaţii false pe Facebook
[Utilizatorii de internet trecuţi de 65 de ani au o tendinţă mai mare de a distribui informaţii false pe Facebook în comparaţie cu internauţii mai tineri.]

3. The race to develop the World’s best Quantum tehnology is on
[China has launched an extremely ambitious program, and so has Europe, the US, the UK, Australia, and Canada.]

4. New system uses a supercomputer and crowd-sourced observations to improve short-term WEATHER predictions
[A team from IBM and The Weather Company introduced a new global weather forecasting system that promises to improve forecasting ability in many parts of the world. The system, called the Global High-Resolution Atmospheric Forecasting System, or GRAF, will work at resolutions of about 3 km (1.8 miles) over land, providing a new daily forecast every hour. For more than about 60 percent of the world — mostly over water, he said — the system will analyze blocks with sides that are about 15 km (9.3 miles) long.]

5. România, pe ultimul loc  în Europa în ce priveşte procentul din PIB alocat cercetării
[România a alocat în 2017 doar 0,5% din Produsul Intern Brut pentru cercetare (R&D), cu mult sub media de 2,07% din PIB cheltuită la nivelul Uniunii Europene]

6. Magnets: How do they stop working?
[Iron becomes magnetic because lots of electrons agree to align their individual magnetic moments. If you hit a thin layer of iron with a strong, very short pulse of light, however, the strength of its magnetic field will drop almost immediately. How does this happen? Well, until now, we weren’t really sure. Thanks to the magic of X-ray lasers we now know why: sound waves carry angular momentum of electrons away.]
