Beneath the surface of Nebelivka’s surrounding landscape and at nearby archaeological sites, 6 ka remnants of what were possibly some of the world’s first cities are emerging from obscurity. These low-density, spread-out archaeological sites are known as megasites, a term that underscores both their immense size and mysterious origins. Now, some scientists are arguing the settlements represent a distinct form of ancient urban life that has gone largely unrecognized. Megasites were cities like no others that have ever existed.
The plan is to have these pods in the Economy cabin, and “an economy-class customer on long-haul flights would be able to book the Economy Skynest in addition to their Economy seat. They would get some quality rest and arrive at their destination ready to go. This is a game changer on so many levels.”
One unlikely but possible scenario is that this “novel” virus is not really novel. Because its symptoms are generally mild and very similar to other symptoms from flu and other viruses, it may have been circulating around the globe for a while, without a name. It can be transmitted by people who have no symptoms at the time or even while they have the virus. If the majority of people infected don’t ever get sick, but easily pass it on, then it can spread widely unseen. But a few are susceptible to it and die. Because the symptoms are not unique to it, this illness is assumed to be flu or something else. Then something happened in China to produce notice — maybe someone created a test for it — and then as people died, the new test found many people positive.
MVRDV is developing a plan for the future of Urban Air Mobility (UAM). The investigation tackles the integration of “flying vehicles” into our urban environments and envisions a comprehensive mobility concept. Addressing major questions like “How will these flying vehicles impact our urban environments? And how could they be leveraged to improve our cities?” MVRDV and Airbus are exploring the possibility of reconnecting territories through an accessible-for-all system. Avoiding the negative impact that comes with the introduction of new transportation modes into cities, the study imagines both short-term and long-term scenarios, in order to dodge any detrimental impacts from this disruptive technology.
Cole was born in 1826 during the administration of John Quincy Adams, was alive at the same time as Ludwig van Beethoven, and lived just long enough to be captured in voice and picture on film.
A patient at a British hospital played Mahler and Gershwin on the violin while a tumour was removed from her brain so that surgeons could preserve her ability to play music and honor her 40-year passion for the instrument. This takes “I’m fully awake during my surgery” to a new level.
Occasionally, sections of a genome will have overlapping sequences that code for different proteins. But in narnaviruses, the entire genome is an overlapping sequence: It can be read in its “reverse complementary” orientation. That is, the RNA is like an ambigram, a stylized script that still says something when flipped upside down.
Antihydrogen does not naturally occur on Earth; physicists first synthesized it in 1995 at CERN. But these particles moved at nearly the speed of light and disappeared in 40 billionths of a second. It would take another 7 years before physicists could produce near-motionless antihydrogen that would not immediately knock into regular matter and annihilate. And it wasn’t until 2010 that they could successfully trap and store antihydrogen. Hangst’s team can now perform experiments for up to 24 hours at a time on the antihydrogen, 12 orders of magnitude in 25 years
