Generating power from the sun isn’t the problem. The technology has been there for decades. Storing that power efficiently, however, has been a challenge.

That’s why the Department of Energy has awarded $3 million to engineering researchers at The University of Texas at Austin to overcome the Achilles’ heel of the solar power story since Day One: how to store its energy.

To date, most major solar energy systems are bulky and expensive, with inefficient storage capacity. Energy coming from existing solar power systems must be housed in storage systems outside of the generators that create the power. In other words, two separate systems are required to ensure successful operation.

The Robots are Coming!

European consumers expect a clean supply chain and biodiversity to be conserved. Therefore, reducing the inputs of pesticides and chemical fertilisers to a minimum and/or replacing them by agro-ecological or robot solutions is required. Furthermore, the average age of European farmers is among the highest of all sectors, thus farming needs to attract young people with attractive working opportunities.

This is where the new agricultural robot solution for precision farming developed within the context of the EU Flourish (Aerial Data Collection and Analysis, and Automated Ground Intervention for Precision Farming) project can play a part. Use of robots in precision farming has the potential not only to increase yield, but also to reduce the reliance on fertilisers, herbicides and pesticides through selectively spraying individual plants or through weed removal.

Wind and solar energy are growing rapidly in the U.S. As these energy sources become a bigger part of the electricity mix, their growth raises new questions: How do solar and wind influence energy prices? And since power plants last for decades, what should policymakers and investors think about to ensure that investments in power infrastructure pay off in the future?

Our research team at the Lawrence Berkeley National Laboratory decided to look at what effect a higher share of wind and solar will have on these questions. In our latest study, we found that high shares of these energy resources lead to several profound changes in electric power systems.

In particular, our study shows how solar and wind tend to lower energy prices, but they add new complexity for operating the grid, which has big implications for regulators. For consumers, this research is a reminder that making the electricity grid cleaner with wind and solar is an evolving process that requires significant changes to how the power grid is currently run—but one that offers large opportunities, if we as a country can become more flexible when we use electricity.

Imec, the world-leading research and innovation hub in nano-electronics and digital technologies, presents this week at its technology forum ITF 2018 (Antwerp, May 23–24), a novel organ-on-chip platform for pharmacological studies with unprecedented signal quality. It fuses imec’s high-density multi-electrode array (MEA)-chip with a microfluidic well plate, developed in collaboration with Micronit Microtechnologies, in which cells can be cultured, providing an environment that mimics human physiology. Capable of performing multiple tests in parallel, the new device aims to be a game-changer for the pharmaceutical industry, offering high quality data in the drug development process.

Every year a handful of new drugs make it to the market, but in their wake tens of thousands of candidate drugs didn’t make the cut. Nevertheless, this journey will have taken a decade and costs billions. The fact that drug development is so time-consuming and costly, is because of the insufficiency of the existing methodologies for drug screening assays. These current assays are based on poor cell models that limit the quality of the resulting data, and result in inadequate biological relevance. Additionally, there is a lack of spatial resolution of the assays, resulting in the inability to screen single cells in a cell culture. Imec’s novel organ-on-chip platform aims to address these shortcomings and challenges.

Imec’s solution packs 16,384 electrodes, distributed over 16 wells, and offers multiparametric analysis. Each of the 1,024 electrodes in a well can detect intracellular action potentials, aside from the traditional extracellular signals. Further, imec’s chip is patterned with microstructures to allow for a structured cell growth mimicking a specific organ.

Although Hurricane Patricia was one of the most powerful storms ever recorded, that didn’t stop the National Oceanic and Atmospheric Administration (NOAA) from flying a scientific aircraft right through it. Now, the researchers have reported their findings, including the detection of a beam of antimatter being blasted towards the ground, accompanied by flashes of x-rays and gamma rays.

Scientists discovered terrestrial gamma-ray flashes (TGFs) in 1994, when orbiting instruments designed to detect deep space gamma ray bursts noticed signals coming from Earth. These were later linked to storms, and after thousands of subsequent observations have come to be seen as normal parts of lightning strikes.

The mechanisms behind these emissions are still shrouded in mystery, but the basic story goes that, first, the strong electric fields in thunderstorms cause electrons to accelerate to almost the speed of light. As these high-energy electrons scatter off other atoms in the air, they accelerate other electrons, quickly creating an avalanche of what are known as “relativistic” electrons.

Researchers at Brown University have discovered a way to stimulate cellular autophagy, which is a natural recycling system built into every cell in the body. This has the potential to combat many age-related neurodegenerative diseases.

What is autophagy?

Autophagy means “eating of self” (from Ancient Greek “auto” = self, “phagein” = to devour). Autophagy is how cells break down broken or dysfunctional organelles and proteins in the cell [1,2]. This essentially means that autophagy can consume organelles, such as mitochondria, peroxisomes, and the endoplasmic reticulum, as part of this process. There is also evidence to support that high levels of autophagy are linked to longevity.
