Nowadays it has become exceedingly hard to distinguish legitimate academic endeavours from scam in my mailbox. Not even AI filters can sort stuff out properly: my inbox often contains invitations to fake conferences, or to publish with non-existing journals, while my spam folder at times contains honest invitations>

First came GRACE (Gravity Recovery and Climate Experiment) and then we'll have GOCE (Gravity field and steady-state Ocean Circulation Explorer). I'll reveal>
The first published results from the Alpha Magnetic Spectrometer (AMS) physics experiment on the International Space Station were announced today and though the result is the most precise measurement to date of the ratio of positrons to electrons in cosmic rays, we still have not caught our first glimpse into dark>
'Cloaking' devices bend electromagnetic waves, such as light, in such a way that it appears as if the cloaked object is not there. In the latest laboratory experiments by Duke researchers, a beam of microwaves aimed through the cloaking device at a "bump" on a flat mirror surface bounced off the surface at the same>
