Οι φόβοι ότι οι προσπάθειες μείωσης των ρύπων στην ατμόσφαιρα θα μπορούσαν να επιταχύνουν δραματικά την διαδικασία της υπερθέρμανσης του πλανήτη μετριάστηκαν μετά τη δημοσίευση μιας νέας μελέτης-ορόσημο.

Η Ιαπωνία εγκρίνει τα πρώτα πειράματα σε έμβρυα ανθρώπου-ζώου
Η έρευνα θα μπορούσε να οδηγήσει τελικά σε νέες πηγές οργάνων για μεταμόσχευση, όμως πρέπει να ξεπεραστούν ηθικές και τεχνικές εμπλοκές.
LHC physicists finally uncover Higgs ‘bottom’ decay
The two largest experiments at the Large Hadron Collider (LHC), ATLAS and CMS, have observed a previously undetected way that the Higgs boson can decay — into an elementary particle called the bottom quark, and its antiparticle._Nature
A surprising chill before the cosmic dawn
An experiment to estimate when stars began to form in the Universe suggests that gas temperatures just before stars appeared had fallen well below predicted limits, and that dark matter is not as shadowy as was thought._ Nature 555, 38-39 (2018)
Γκαίτε … ραψωδία για την Φύση
Ενδεχομένως το πλέον ενδεδειγμένο προοίμιο για την επίσημη πρώτη έκδοση της έντυπης επιθεώρησης Nature [4 Νοεμβρίου, 1869] στόχος της οποίας ήταν να αντικατοπτρίσει στον ανθρώπινο νου το είδωλο της μορφής που η ίδια η Φύση επιλέγει για εικόνα της —αυτό που όλοι μας αποκαλούμε πρόοδο της επιστήμης.
Cosmic-ray particles reveal secret chamber in Egypt’s Great Pyramid
Physicists have used the by-products of cosmic rays to reveal a large, previously unidentified chamber inside the 4,500-year-old Great Pyramid in Giza, Egypt. The find is the first discovery since the nineteenth century of a major new space inside the pyramid. _Nature
Antikythera shipwreck yields statue pieces and mystery bronze disc
Marine archaeologists investigating the ancient shipwreck that yielded the Antikythera mechanism — a complex, bronze, geared device that predicted eclipses and showed the movements of the Sun, Moon and planets in the sky — have recovered a wealth of treasures, including bronze and marble statue pieces, a sarcophagus lid and a mysterious bronze disc decorated with a bull. The artefacts were trapped under boulders in a previously unexplored part of the site near the island of Antikythera, Greece, and the researchers think that large parts of at least seven statues are still buried nearby. _Nature News & Comment
Research sheds new light on how Earth and Mars were created
Analysing a mixture of earth samples and meteorites, scientists from the University of Bristol have shed new light on the sequence of events that led to the creation of the planets Earth and Mars.
Oldest traces of life on Earth may lurk in Canadian rocks
Ancient rocks in northeastern Canada could contain chemical traces of life from more than 3.95 billion years ago, a new study suggests. If confirmed, the finding would be among the earliest known signs of life on Earth._Nature News & Comment
