We also know from the geological record that this ice sheet is capable of rapid collapses, and has sometimes thinned at rates in excess of 30 feet (10 meters) per year. Recent models show sea level could rise by 1 meter by 2100 and 15 meters by 2500 if greenhouse gas emissions continue to rise at current rates and the ice sheet experiences a rapid collapse, as it has in the past. … [Read more...] about Russian explorers discovered Antarctica 200 years ago.

"Unfortunately, it's one of those specimens that was discovered probably 50 years too late," Makovicky told Live Science.

But researchers didn't know any of these details at first; originally, they found only the dinosaur's skeleton but not the head.

None of this was necessary Kedrosky's speculation on the difficulty of discovery takes an extremely narrow view of what constitutes "progress," and it never bothers to define what's "difficult." It's hard to begrudge him this speculation, given that it ends in a paean to human creativity in the sciences and elsewhere. But by eliding almost all of the details, his conclusion—"things are getting harder, and they will continue to do so"—doesn't provide much in the way of perspective or understanding. Kedrosky dismisses a real factor in the rate of discovery as "too pat" and doesn't fully recognize the limits of his own supporting evidence; he writes with confidence about something he doesn't seem to fully understand. … [Read more...] about Is scientific progress slowing? Depends how you measure it
Who was Takabuti?Although Takabuti was from ancient Thebes (today's Luxor), her mummy got caught up in the intense Egyptian mummy trade that followed the Napoleonic Wars. When Thomas Greg, a wealthy Irish man, acquired her remains in 1834 and brought them from Egypt to Belfast, Takabuti was the first known Egyptian mummy to reach Ireland. … [Read more...] about Egyptian mummy cold case closed: ‘Takabuti’ was stabbed to death
