Tissue engineering: The big picture on growing small intestines

Babies born prematurely often face intense medical challenges, including intestines that are underdeveloped or diseased. While an intestine transplant can benefit some patients, many babies are simply too small to endure this procedure. Children's Hospital Los Angeles surgeon Tracy Grikscheit, MD, is a leader in the field of tissue engineering—growing intestines from stem cells. In an article published in the journal Cell Stem Cell, Dr. Grikscheit and co-authors highlight how stem cell therapy is poised to become a game-changer for these babies.

How much would you pay to eliminate child labor from your cocoa?

An increase in cocoa price by 2.8 percent could potentially eliminate the very worst forms of child labor from cocoa production in Ghana, according to a new economic model described in a study published June 5, 2019 in the open-access journal PLOS ONE by Jeff Luckstead and Lawton L. Nalley from the University of Arkansas, USA, and Francis Tsiboe from Kansas State University, USA.

Cracking open the black box of automated machine learning

Researchers from MIT and elsewhere have developed an interactive tool that, for the first time, lets users see and control how automated machine-learning systems work. The aim is to build confidence in these systems and find ways to improve them.

How brassinosteroid signaling makes roots grow longer under nitrogen deficiency

As sessile organisms, plants rely on their ability to adapt the development and growth of their roots in response to changing nutrient conditions. One such response, known to be displayed by plants grown in low nitrogen conditions, is the elongation of primary and lateral roots to explore the surrounding soil. This adaption to the lack of the essential element nitrogen is of particular interest, as it reflects a "foraging strategy," by which the root system can exploit nutrients from a larger soil volume. Until recently, this was the least understood nitrogen-dependent root response. Scientists from the IPK in Gatersleben have now identified the hormone pathway regulating root foraging under low nitrogen conditions and a signalling component that modulates the intensity of this response. These findings open up the possibility of breeding crops with root systems enabling more efficient nitrogen uptake.

Researchers find ways to hackproof smart meters

Smart electricity meters are useful because they allow energy utilities to efficiently track energy use and allocate energy production. But because they're connected to a grid, they can also serve as back doors for malicious hackers.

Somebody's watching you: The surveillance of self-driving cars

Picture the future, where driving is a thing of the past. You can hop in your car or one from a ride-share, buckle up and tell the car where you want to go. During your ride, you can check your email and look up a few things online through your dashboard. Meanwhile, your whereabouts and other details are being tracked remotely by companies. As self-driving cars develop further, autonomous vehicles will play a much larger role in the digital economy as car companies and others harness personalized customer information through geospatial and navigation technologies, combining it with existing financial consumer profiles, according to a study in Surveillance and Society.
