By analyzing a global sample of 4 million authors and 26 million scientific papers

...this study finds that the top 1% most-cited scientists have increased their cumulative citation shares from 14 to 21% between 2000 and 2015 and that the Gini coefficient for citation imbalance has risen from 0.65 to 0.70.

Commission and parliament in secret talks on EU copyright directive

High-ranking representatives of the European Commission’s DG Connect will brief EU lawmakers as part of an ‘in camera’ meeting on Friday (12 February), after a contingent of parliament members wrote to the EU executive to voice their concerns on guidance issued for the EU’s copyright directive. ... The EU executive then issued draft guidance as a result of the consultations last year, but there has been criticism that the guidance does not offer the clarity required for rightsholders. The guidance came in for a backlash from some member states, including Croatia, Denmark, France, Greece, Italy, Portugal, and Spain, who penned a non-paper highlighting their worries that the guidance would not achieve the objectives originally set out by the Commission in supporting Europe’s rightsholders. ...
