Sci-Fi Promised Us Home Robots. So Where Are They?
Science fiction has promised us a whole lot of technology that it’s rudely failed to deliver—jetpacks, flying cars, teleportation. The most useful one might be the robot companion, à la Rosie from The Jetsons, a machine that watches over the home.
It seemed like 2018 was going to be the year when robots made a big leap in that direction. Two machines in particular surfaced to much fanfare: Kuri, an adorable R2D2 analog that can follow you around and take pictures of your dinner parties, and Jibo, a desktop robot with a screen for a face that works a bit like Alexa, only it can dance.

Virgin Galactic’s Historic Space Trip Heralds a Coming Age of New US Human Spaceflight Leaps
Virgin Galactic just brought human spaceflight back to American soil after a seven-year hiatus, and other private companies are poised to make some giant leaps of their own.
Virgin’s VSS Unity suborbital spaceliner soared to a maximum altitude of 51.4 miles (82.7 kilometers) during a rocket-powered test flight over California’s Mojave Desert yesterday (Dec. 13).
The milestone marked the first U.S.-based crewed trip to the final frontier since NASA grounded its space shuttle fleet in July 2011. And it was the first spaceflight ever by a private vehicle designed to carry commercial passengers. (By one measure, anyway: Though many people place the boundary of outer space 62 miles, or 100 km, up at the “Karman Line,” the U.S. Air Force awards astronaut wings to personnel who reach an altitude of 50 miles, or 80 km.)

Branson’s Virgin reaches edge of space
The latest test flight by Sir Richard Branson’s Virgin Galactic successfully rocketed to the edge of space and back.
The firm’s SpaceShipTwo passenger rocket ship reached a height of 82.7km, beyond the altitude at which US agencies have awarded astronaut wings.
It marked the plane’s fourth test flight and followed earlier setbacks in the firm’s space programme.
Today, Virgin Galactic will fly their first mission for us — and join the growing list of commercial vehicles supporting our suborbital research
Payloads on the flight will collect valuable data to improve technologies for future exploration missions. This flight will be specifically be used to study how dust disperses in microgravity. Understanding dust dynamics can help abate the damage that is caused by particles contaminating hardware and habitats. Swoop in: https://go.nasa.gov/2Gr79YT
Indian academia is fighting a toxic mix of nationalism and pseudoscience
It’s a problem that has many academics here worried. As India becomes increasingly polarised, coordinated efforts to popularise pseudoscientific theories, and to aggrandise the nation’s own scientific past, have begun to gain ground, they say. It’s a worrying mash-up of nationalism, religion, and scientific bunkum that appears to be an increasingly easy sell—and one that leaves the population both misinformed and perennially at odds with itself. “That is why our leaders and scientists talk about how evolution is wrong,” said Aniket Sule, an astrophysicist and colleague of Karandikar at HBCSE, “or how Indians were first to invent plane or atomic theory, or how cow worship is scientific.”
A wave of superstitions is being promoted as legitimate science.
First look at a bulletproof Tesla Model X armored vehicle
Electric vehicles, especially Tesla’s vehicles, are not being left out when it comes to armored vehicles.
After a Model S earlier this year, we’ve now got a look at what could be the first Tesla Model X armored vehicle.
We heard a rumor that Tesla’s showroom in Mexico City was displaying a bulletproof Model X.
Antarctic Scientists Are About to Drill Into One of the Most Isolated Lakes on Earth
Buried beneath 4,000 feet of Antarctic ice lies Lake Mercer, a subglacial body of water that formed thousands of years ago and has been long separated from the rest of the world. A project to explore this lake—and its mysterious contents—is finally set to begin later this month.
Called Subglacial Antarctic Lakes Scientific Access, or SALSA for short, the project aims to uncover new knowledge about Antarctica’s subglacial lakes, of which over 400 are known to exist. Over the next two months, SALSA scientists will explore one of the largest subglacial lakes in West Antarctica, a body of water known as Lake Mercer. The team will bore through some 4,000 feet (1,200 meters) of ice using a 60-centimeter-wide drill capped with hot water. In addition to extracting water and mud samples, the researchers will deploy a remotely operated vehicle—a scientific first for a subglacial lake.
