4.Drones Aim to Carry Human Lives
Delivery drones have yet to begin showing up at doorsteps with packages from Amazon. But a new breed of drones could eventually begin carrying the most precious package of all in the form of human lives.
One such passenger drone resembles a giant quadcopter that can carry a single passenger on 23-minute flights at speeds of about 62 miles per hour. The Chinese startup EHang unveiled the drone, called the Ehang 184, at the 2016 Consumer Electronics Show in Las Vegas in early January. Passengers use a tablet to set waypoints for the drone to follow and can click once for both takeoff and return, but the drone itself automatically handles the rest of the flying decisions. EHang representatives told Tech Insider and other news publications that they hope the passenger drone can hit the market starting sometime in 2016.

6.Levitating Rocket Sled Breaks World Speed Record
A levitating rocket sled at Holloman Air Force Base in New Mexico recently broke the world speed record for maglev tracks, clocking in at 633 mph.
The rocket sled, which is basically a rocket bolted to a small platform, achieved such high speeds thanks to supercooled magnets that hold the sled about an inch off of the rails, allowing it to hover in midair. With only wind resistance holding it back, the sled and its rocket booster surpassed the previous record — set earlier this year by the same sled — with ease.

7.Artificial Pancreas Makers Race to Market
The technology, a potential life-saver for those with Type 1 diabetes, is almost here. Which team will be the first to bring it to patients?
Ed Damiano has pushed to develop what he describes as a bionic pancreas for his teenage son, David. The device would control his son’s blood sugar with computer precision, pumping not only the hormone insulin, but also the glucose-raising hormone glucagon. Damiano and research partner Steven Russell have been developing the bionic pancreas for 12 years

Strolling through a nature preserve near the Old North Bridge in Concord, Mass., where “the shot heard ’round the world” began the American Revolutionary War, Ed Damiano is talking about another revolution, this one in the care of his son’s Type 1 diabetes. Call it the insulin shot heard ’round the world, delivered not with a handheld syringe, but automatically, from a computer-guided pump: the diabetic answer to the driverless car.

In this time-lapse series of photos, progressing from top to bottom, a coating of sucrose (ordinary sugar) over a wire made of carbon nanotubes is lit at the left end, and burns from one end to the other. As it heats the wire, it drives a wave of electrons along with it, thus converting the heat into electricity.
Engineers from MIT have developed an alternative system for generating electricity, which harnesses heat and uses no metals or toxic materials.
The batteries that power the ubiquitous devices of modern life, from smartphones and computers to electric cars, are mostly made of toxic materials such as lithium that can be difficult to dispose of and have limited global supplies. Now, researchers at MIT have come up with an alternative system for generating electricity, which harnesses heat and uses no metals or toxic materials.

An artist’s rendering of a calcium liquid battery.
In a newly published study, MIT researchers show that calcium can form the basis for both the negative electrode layer and the molten salt that forms the middle layer of the three-layer battery.
Liquid metal batteries, invented by MIT professor Donald Sadoway and his students a decade ago, are a promising candidate for making renewable energy more practical. The batteries, which can store large amounts of energy and thus even out the ups and downs of power production and power use, are in the process of being commercialized by a Cambridge-based startup company, Ambri.

13.MIT Researchers Create Perfect Nanoscrolls from Graphene Oxide
An electron microscopy image shows many examples of nanoscrolls. The insert zooms in on a single nanoscroll and reveals its conical nature.
Using both low- and high-frequency ultrasonic techniques, scientists have fabricated nanoscrolls made from graphene oxide flakes.
Water filters of the future may be made from billions of tiny, graphene-based nanoscrolls. Each scroll, made by rolling up a single, atom-thick layer of graphene, could be tailored to trap specific molecules and pollutants in its tightly wound folds. Billions of these scrolls, stacked layer by layer, may produce a lightweight, durable, and highly selective water purification membrane.

In search of the ideal bacteria for use in a microbial fuel cell, researchers from MIT have developed a new microfluid device to quickly sort and identify the various strains. This technology, which could lead to a carbon-neutral method of harvesting energy for the grid from wastewater, may also be useful to doctors in identifying deadly infections more quickly.
Genetically engineering any organism requires first getting its cells to take in foreign DNA. To do this, scientists often perform a process called electroporation, in which they expose cells to an electric field.
