From precision GPS to batteries for one of the world’s first commercial all-electric airplanes, NASA technology turns up in nearly every corner of modern life. The latest edition of NASA’s Spinoff publication features dozens of commercial technologies that were developed or improved by the agency’s space program and benefit people everywhere.

“NASA works hard, not only to develop technology that pushes the boundaries of aeronautics and space exploration, but also to put those innovations into the hands of businesses and entrepreneurs who can turn them into solutions for challenges we all face here on Earth,” said Jim Reuter, acting associate administrator of the agency’s Space Technology Mission Directorate. “These are sometimes predictable, like the many NASA technologies now adopted by the burgeoning commercial space industry, but more often they appear in places that may seem unrelated, like hospitals, farms, factories and family rooms.”

Oops, duh, Eureka… shouted Archimedes… Or something.

Corn leaves are teaming with bacteria communities (the leaf “microbiome”) that influence plant health and performance, and scientists are still figuring out how. A team of scientists led by Dr. Jason Wallace recently published a study in the open access Phytobiomes Journal that advances what we know about these bacterial communities by investigating their relationships with corn genetics. According to Dr. Wallace, “the end-goal of all this research is to understand how crops interact with their microbial communities so we can harness them to make agriculture more productive and sustainable.”

In one of the largest and most diverse leaf microbe studies to date, the team monitored the active bacteria on the leaves of 300 diverse lines of corn growing in a common environment. They were especially interested to see how corn genes affected bacteria and found there was little relationship between the two — in fact, the bacteria were much more affected by the environment, although genetics still had a small role.

This is an interesting discovery that “breeding probably isn’t the best way to address this,” Dr. Wallace says. Instead, “the leaf community is probably better changed through farmer management.” That is, farmers should be able to change growing practices to enhance their current crops rather than seek out new plant varieties.

Robotics are going to become common in farming, reducing the need for back-breaking labor.

NUI Galway will lead a new €13 million SFI Centre for Research Training in Genomics Data Science. The new Centre will train a generation of 100 highly skilled PhD graduates to harness the collective potential of genomics and data science to have transformative scientific, economic and societal impacts.

Announced recently by Minister Heather Humphreys TD Minister for Business, Enterprise, and Innovation, and Minister of State for Training, Skills, Innovation, Research and Development, John Halligan TD and Science Foundation Ireland, the Centre will be led by NUI Galway and will involve partners from UCD, TCD, RCSI and UCC.

A genome is an organisms complete set of DNA or genetic material and it contains all of the information needed to build and maintain that organism. Genomics is the branch of science that studies genomes to see how they direct the growth and function of cells and organisms and it is a key area of fundamental science with real-world impacts in areas from human health to agriculture and food production. In recent years the field of genomics has undergone a revolution, driven by new technologies that generate data on an enormous scale. In order to make sense of the large and complex datasets arising from analysis of genomes, we require highly trained data scientists, who can turn this data into useful information that can increase scientific understanding and enable us to harness the power of genomics to drive innovation and create real-world solutions.

The Urban Farmer is a comprehensive, hands-on, practical manual to help you learn the techniques and business strategies you need to make a good living growing high-yield, high-value crops right in your own backyard (or someone else’s).

Bio-PDO — Susterra propanediol produced by DuPont Tate & Lyle Bio Products — are among the many smart applications of corn, and constitute the building blocks of a number of environmentally friendly materials, increasingly used in the footwear manufacture.

We are all familiar with sweetcorn or corn on the cob and many of us enjoy eating it boiled and coated in butter. Americans in particular are especially fond of it although less than 1% of all the corn grown annually in the USA is for human consumption. The remaining 99% is industrial corn or maize which is used for animal feed and for processing into a variety of other products. Among these is Bio-PDO or, to give it its commercial name, Susterra propanediol produced by DuPont Tate & Lyle Bio Products, which is used as a basis for a number of environmentally friendly materials, increasingly used in footwear manufacture.

The variety of corn involved is known as yellow dent and has a high starch content. After harvesting and drying, it is transported to Tate & Lyle’s wet mill at Loudon, Tennessee. Using a wet milling process, the corn is separated into its four basic components: starch, germ, fibre and protein. The nutrient rich components are used for animal feed while glucose is derived from the remaining starch fraction and is the raw material used for making 1.3- propanediol. The process starts off with a culture of a special microorganism in a small flask with the glucose. As it grows, it is transferred to a seed fermenter, followed by a ten-story high production fermenter. Fermentation takes place under exact temperature conditions and involves a patented process where the microorganism functions as a biocatalyst, converting glucose into biobased 1.3-propaneidol.

NEW ORLEANS—Exposure to the widely used chemical bisphenol A (BPA) during pregnancy, even at levels lower than the regulated “safe” human exposure level, can lead to changes in circadian rhythms, according to a mice study to be presented Monday at ENDO 2019, the Endocrine Society’s annual meeting in New Orleans, La. The researchers report these changes may be a contributing factor in hyperactivity seen in BPA-exposed mice.

“The hypothalamus, which we have identified as a brain region that is particularly susceptible to developmental disruption by BPA, contains the site of the clock cells that govern daily rhythms throughout the body,” said researcher Deborah Kurrasch, Ph.D., Associate Professor at the University of Calgary in Calgary, Canada. “We have shown in previous research that BPA exposure in utero can cause defects to the development of hypothalamic nuclei and hyperactivity, and here we explored whether a shift in circadian biology might explain why the animals moved more.”

BPA is a chemical that is added to many commercial products, including water bottles, paper receipts, can liners and food storage containers. It is known as an endocrine-disrupting chemical—a chemical that interferes with the body’s hormones.

New research from Washington University in St. Louis explains the cellular processes that allow a sun-loving microbe to “eat” electricity—transferring electrons to fix carbon dioxide to fuel its growth.

Led by Arpita Bose, assistant professor of biology in Arts & Sciences, and Michael Guzman, a Ph.D. candidate in her laboratory, a Washington University team showed how a naturally occurring strain of Rhodopseudomonas palustris takes up electrons from conductive substances like metal oxides or rust. The work is described in a March 22 paper in the journal Nature Communications.

Unmanned systems’ global inroads are including European agriculture. GNSS for precision guidance of tractors and harvesters is already in place. More recent innovations include fully driverless and smart systems, while drones remain poised to fly.

The experience of one Dutch company is instructive. Precision Makers is an up-and- coming manufacturer of automated farm systems. The company delivers two main products. One, a conversion kit called X-Pert, turns existing mowers and tractors into driverless machines. The other is a fully robotized, unmanned vehicle called Greenbot. Both systems enable automated precision operations, but while one has been successful in terms of sales, the other has not.

Precision Makers Business Development Director, Allard Martinet, told Inside Unmanned Systems, “Sales of our X-Pert conversion system have been very good. We started in 2008, first converting the Toro golf course mower, and then we expanded that into solutions for other vehicles. Today, there are more than 150 X-Pert converted vehicles running.”
