The new T models take Porsche's lowest-spec, 2.0-liter, 296-hp sportscars and trick them out with the kinds of options you'd want on a hard driving car. The cars serve as a kind of rolling proof that it can be more fun to drive a slow car fast than a fast one.

BAE Systems and General Dynamics have been tapped by the US Army to each build 12 prototype medium-armor vehicles. Part of the development phase of the Mobile Protected Firepower program, the US$376-million contracts aim to develop an agile, multi-terrain platform for Infantry Brigade Combat Teams.

​It was just this July that Japan's Yanmar Agri Corporation unveiled a line of driverless agricultural tractors. Now, as part of the same Smartpilot system, the company has announced an autonomous rice seedling-transplanter.

​Back in August, Nuro partnered with supermarket retailer Kroger to make autonomous grocery deliveries in Scottsdale, Arizona. Initially, the pilot program made use of a fleet of self-driving Prius hybrids, but now the first unmanned deliveries have been made with Nuro's R1 pod.​

An advanced "sound tweezer" can manipulate dozens of objects independently using hundreds of tiny speakers, allowing for noninvasive surgery and a new, highly interactive type of 3D display.

​When McGill University's Dr. Sheila Wang was in medical school, she noticed that doctors simply used rulers to measure patients' diabetic skin ulcers. Figuring that there had to be a more precise, objective method of doing so, she went on to create the new Swift Skin and Wound app.

The camera world didn't offer up a whole lot of big surprises in 2018. The trends that became clear in 2017 were taken to new heights, with big sensor mirrorless rigs taking center stage, putting medium format and full frame horsepower into ever smaller and lighter bodies.

A Harvard team has developed small, insect-like robots that can climb inside machines to inspect them, saving the trouble of pulling them apart if there’s nothing that needs fixing.

​While plants do help clean the air within a home, it is estimated that over 20 per room would be required to make a difference. That likely wouldn't be the case with a new genetically-modified ivy, however, which has proven to be highly effective at removing chloroform and benzene from the air.

The New Horizons spacecraft is just a few weeks out from a historic flyby of the Kuiper Belt object, 2014 MU69 (Ultima Thule). After weeks of scans for any potential hazards, NASA has now given the all-clear to buzz the object on an optimal path, which will bring it in closer for a much better look.

DNA is the building material of life, but recent work shows it can also be used to make art or even store data. Now, a team at Caltech has used DNA to make the world’s smallest game of tic-tac-toe, and the technique could have applications in designing reconfigurable nanomachines.

​Ordinarily, city officials only know about leaks in municipal water pipes once those leaks have become quite large and troublesome. A new artificial intelligence-based system, however, could catch such leaks much earlier – by listening for them.
