For the first time, scientists have created pigs, goats and cattle that can serve as viable “surrogate sires,” male animals that produce sperm carrying only the genetic traits of donor animals.

The advance, published in the Proceedings of the National Academy of Sciences on Sept. 14, could speed the spread of desirable characteristics in livestock and improve food production for a growing global population. It also would enable breeders in remote regions better access to genetic material of elite animals from other parts of the world and allow more precision breeding in animals such as goats where using is difficult.

“With this technology, we can get better dissemination of desirable traits and improve the efficiency of food production. This can have a major impact on addressing food insecurity around the world,” said Jon Oatley, a reproductive biologist with WSU’s College of Veterinary Medicine. “If we can tackle this genetically, then that means less water, less feed and fewer antibiotics we have to put into the animals.”

ETH researchers are making chocolates shimmer in rainbow colors without the addition of colorants. They have found a way to imprint a special structure on the surface of the chocolate to create a targeted color effect.

Traditional methods for coloring have been around for a long time. But the ETH researchers are able to create the rainbow effect without artificial colorants. The effect is achieved simply through a surface imprint that produces what the scientists refer to as a structural color. The process is similar to a chameleon, whose skin surface modulates and disperses light to display specific colors.

The story begins in the shared corridor of a university building. The food scientist Patrick Rühs, the materials scientist Etienne Jeoffroy and the physicist Henning Galinski chat about chocolate during their coffee break. Although they work in different research groups, their offices are next to each other. They wonder how—and whether—it might be possible to make colored chocolate. Rühs is studying the material properties of foodstuffs, Jeoffroy specializes in complex materials and Galinski has already done in-depth research into optical materials.

The research, out today from the University of Colorado Anschutz Medical Campus and published in * Evolution and Human Behavior*, presents a hypothesis supporting a role for fructose, a component of sugar and high fructose corn syrup, and uric acid (a fructose metabolite), in increasing the risk for these behavioral disorders.

Johnson outlines research that shows a foraging response stimulates risk taking, impulsivity, novelty seeking, rapid decision making, and aggressiveness to aid the securing of food as a survival response. Overactivation of this process from excess sugar intake may cause impulsive behavior that could range from ADHD, to bipolar disorder or even aggression.” “Johnson notes, “We do not blame aggressive behavior on sugar, but rather note that it may be one contributor.”” “The identification of fructose as a risk factor does not negate the importance of genetic, familial, physical, emotional and environmental factors that shape mental health,” he adds.

Huh, want to know more.

“New research suggests that conditions such as attention deficit hyperactivity syndrome (ADHD), bipolar disorder, and even aggressive behaviors may be linked with sugar intake, and that it may have an evolutionary basis.

The research, out today from the University of Colorado Anschutz Medical Campus and published in Evolution and Human Behavior, presents a hypothesis supporting a role for fructose, a component of sugar and high fructose corn syrup, and uric acid (a fructose metabolite), in increasing the risk for these behavioral disorders.

“We present evidence that fructose, by lowering energy in cells, triggers a foraging response similar to what occurs in starvation,” said lead author Richard Johnson, MD, professor at the University of Colorado School of Medicine on the CU Anschutz Medical Campus.

In 2016, I proposed LEO HTS Mega Constellation a viable solution for Australia’s broadband national coverage. I have been doing research on these constellations right from the beginning and they are inevitable!

Introduction

Utilizing the announced Lower Earth Orbit (LEO) satellites constellations of OneWeb, SpaceX, LeoSat & Samsung to provide high speed connectivity to entire Australian continent with performance better than fiber networks. This project can eliminate high cost NBN roll out to scattered populations and will considerably improve disaster management. Providing high speed connectivity for mobile communication, internet, high resolution TV broadcast as well as utilizing technologies like IoT & Cloud for improvement in security, education, health, agriculture, livestock farming, mineral resources, wildlife, and environment without any coverage black-spots. This network will not require any infrastructure installations and will help the Government to generate revenues by issuing spectrum licenses to local as well as foreign investors for providing services directly to the end user.

Mineral’s plant buggy looks like a platform on wheels, topped with solar panels and stuffed with cameras, sensors, and software.

But maybe there’s a better way—and Mineral wants to find it.

Like many things nowadays, the key to building something better is data. Genetic data, weather pattern data, soil composition and erosion data, satellite data… The list goes on. As part of the massive data-gathering that will need to be done, X introduced what it’s calling a “plant buggy” (if the term makes you picture a sort of baby stroller for plants, you’re not alone…).

It is in fact not a stroller, though. It looks more like a platform on wheels, topped with solar panels and stuffed with cameras, sensors, and software. It comes in different sizes and shapes so that it can be used on multiple types of crops (inspecting tall, thin stalks of corn, for example, requires a different setup than short, bushy soybean plants). The buggy will collect info about plants’ height, leaf area, and fruit size, then consider it alongside soil, weather, and other data.
