It has long been known that brains create folds as they grow, but the physics of the process has remained elusive. Now Israeli scientists have found a way to witness brain cell growth using a 150-micrometer-thick, gel-lined chip topped with organoids and then covered -- creating a 2D environment that makes it easier to see the process in action.
Scaffolds can be used to grow tumor cells taken from cancer patients so clinicians can experiment with different treatments. Through a startup called Advanced Culture Systems, a researcher from the University of Oklahoma has developed an improved method of 3D printing scaffolds to allow for more rapid and useful cell growth.
A guitar-making class in a Pennsylvania high school is engaging students in a fun way to use science, technology, engineering and math concepts. Tech-ed teacher Matt Peitzman uses STEM Guitar curriculum in the class.

The Trump administration's proposed fiscal 2019 budget would set aside $18 million for the first eight over-the-horizon missiles for the Navy's littoral combat ships. In addition, the Navy plans to acquire 12 of the missiles annually from 2020 to 2022 and 20 in fiscal 2023.
An $11.9 million service contract is going to General Dynamics for the Navy's Surface Electronic Warfare Improvement program. The contract includes options for onboard electronic warfare countermeasures providing early detection and protection from anti-ship missiles.
The Navy's Zumwalt-class stealth destroyers will take on new missions as anti-surface, offensive strike platforms if funding for their conversion is approved by Congress. The changes would include integration of Raytheon's long-range anti-air and anti-surface SM-6 missile in addition to the Tomahawk missile's Maritime Strike variant.
DNV GL is addressing the problem of stern tube bearing failure with new class rules for single stern tube bearing installations and two class notations. The changes focus on bearing damages most commonly observed in the aft-most part of the aft bearing during starboard turns on right-handed propeller installations.
Five companies will be producing conceptual designs for the Navy's future FFG(X) frigate under $15 million in newly awarded contracts. The companies are Huntington Ingalls, Lockheed Martin, Austal USA, General Dynamics Bath Iron Works and Italy's Fincantieri.
