Alien megastructure is ‘just dust — An analysis by more than 200 astronomers has been published that shows the mysterious dimming of star KIC 8462852 – nicknamed Tabby’s star – is not being produced by an alien megastructure. The evidence points most strongly to a giant cloud of dust occasionally obscuring the star, reports The Guardian.
~ Well to me, that’s a relief. But hey, surely a cloud of dust should have been their first call, not ‘alien megastructure’?!
The border of earth and space — A new NASA mission, the first to hitch a ride on a commercial communications satellite, will examine Earth’s upper atmosphere to see how the boundary between Earth and space changes over time. GOLD stands for Global-scale Observations of the Limb and Disk, and the mission will focus on the temperature and makeup of Earth’s highest atmospheric layers.
~ Another mission, another future iteration of space junk.
Smart bot could build homes on Mars — Built by the German space agency DLR, humanoid bots are being groomed to build the first Martian habitat for humans. Engineers have been refining Justin’s physical abilities for a decade; the mech can handle tools, shoot and upload photos, catch flying objects, and navigate obstacles.
Now, thanks to new AI upgrades, Justin can think for itself.
~ Here’s a better idea – the smart Alec can build a house for itself on Mars.
Soft robot may actually be useful — A burgeoning field called soft robotics promises to bring more “natural” movements to the machines. And today, a pair of papers in Science and Science Robotics detail a clever new variety of robotic “muscle,” a series of oil-fueled pouches activated with electricity. This actuator (aka the bit that moves a robot) is as strong and efficient as human muscle, but can pull off more contractions per second. Which could make for a prosthesis that moves more naturally, perhaps—or maybe farther down the road, soft yet strong robots that help you around the house without accidentally terminating you.
~ And I honestly do prefer not being accidentally terminated.
Ancient Americans we didn’t know about — She died 11,500 years ago at the tender age of six weeks in what is now the interior of Alaska. Dubbed ‘Sunrise Girl-child’by the local indigenous people, the remains of the Ice Age infant, uncovered at an archaeological dig in 2013, contained traces of DNA, allowing scientists to perform a full genomic analysis. Incredibly, this baby girl belonged to a previously unknown population of ancient Native Americans – a discovery that’s changing what we know about the continent’s first people.
All Native Americans can trace their ancestry back to a single migration event that happened at the tail-end of the last Ice Age. The evidence, gleaned from the full genomic profile of the six-week-old girl and the partial genomic remains of another infant, suggests the continent’s first settlers arrived in a single migratory wave around 20,900 years ago. But this population then split into two groups: one group that would go on to become the ancestors of all Native North Americans, and another would venture no further than Alaska. This is a previously unknown population of ancient North Americans now dubbed the Ancient Beringians.
~ Then they got ‘back-migrated’.
Ancient dinosaur eggs perfectly preserved — Chinese construction workers digging on Christmas day found a gift that was wrapped 130 million years ago in the form of 30 incredibly preserved dinosaur eggs. The discovery was made in the city of Ganzhou at the future site of a new middle school, but work on the new facility had to be put on hold after the ancient eggs were discovered.
~ Here’s the plan, then: grind them into snake oil medicine.
