What was behind the 2021-2022 energy crisis within Europe?      (via sciencedaily.com)     Original source 

A team of researchers had already been working with electricity price data for years before Russia's invasion of Ukraine, exploring statistics and developing forecasting methods. Now they zero in on how prices in different countries relate and how countries were affected by the energy crisis and address the interdependencies of different markets. Their approach combines statistical physics and network science, identifying communities and the fundamental spatiotemporal patterns within the electricity price/time data from all countries. The researchers hope their work will strengthen the European perspective in the political debate about electricity markets and prices, because problems like this are best tackled via international cooperation.

A new breakthrough in understanding regeneration in a marine worm      (via sciencedaily.com)     Original source 

The sea worm Platynereis dumerilii is only a few centimeters long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation. By focusing more specifically on the mechanisms at play in the regeneration of this worm's tail, a research team has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis.

Research shows how RNA 'junk' controls our genes      (via sciencedaily.com)     Original source 

Researchers have made a significant advance in understanding how genes are controlled in living organisms. The new study focuses on critical snippets of RNA in the tiny, transparent roundworm Caenorhabditis elegans (C. elegans). The study provides a detailed map of the 3'UTR regions of RNA in C. elegans. 3'UTRs (untranslated regions) are segments of RNA involved in gene regulation.

Researchers thwart resistant bacteria's strategy      (via sciencedaily.com)     Original source 

Bacteria are experts at evolving resistance to antibiotics. One resistance strategy is to cover their cell walls in sticky and gooey biofilm that antibiotics cannot penetrate. A new discovery could put a stop to this strategy.

Characterization of the extraordinary thermoelectric properties of cadmium arsenide thin films      (via sciencedaily.com)     Original source 

If there's one thing we humans are good at, it's producing heat. Significant amounts, and in many cases most of the energy we generate and put into our systems we lose as heat, whether it be our appliances, our transportation, our factories, even our electrical grid.

From takeoff to flight, the wiring of a fly's nervous system is mapped      (via sciencedaily.com)     Original source 

Although a fly's motor neurons are few, it performs remarkable aerial and terrestrial feats. A wiring diagram recently created of the motor circuits in the central nervous system of the fruit fly is providing detailed information on how the nerve coordination of leg movements differs from that controlling the wings. Such studies reveal the unexpected complexity of the fly's tiny motor system. They also advance the understanding of how the central nervous system in animals coordinates individual muscles to carry out a variety of behaviors.

Cell division: Before commitment, a very long engagement      (via sciencedaily.com)     Original source 

Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours -- sometimes more than a day -- in a reversible intermediate state, according to a new discovery. Their revelation of this fundamental feature of biology includes details of its mechanisms and dynamics, which may inform the development of future therapies targeting cancers and other diseases.

The on-and-off affair in DNA      (via sciencedaily.com)     Original source 

Researchers have discovered that in thale cresses histone H3 lysine-9 (H3K9) methylation, conventionally thought to be a mark of turning off gene transcription, can also turn on gene expression via the interactions of two other proteins and histone marks. The molecular mechanisms demonstrate that rather than functioning as a simple 'off switch,' H3K9 methylation is more like a 'dimmer switch' that fine-tunes DNA transcription. The discovery suggests there might be similar mechanisms in other organisms, too.

Zebrafish reveal how bioelectricity shapes muscle development      (via sciencedaily.com)     Original source 

New research describes how nerve cells and muscle cells communicate through electrical signals during development -- a phenomenon known as bioelectricity. The communication, which takes place via specialized channels between cells, is vital for proper development and behavior. The study identifies specific genes that control the process, and pins down what happens when it goes wrong. The finding offers clues to the genetic origins of muscle disorders in humans.

Discovery of vast sex differences in cellular activity has major implications for disease treatment      (via sciencedaily.com)     Original source 

The study reveals vast differences in gene activity within the mitochondria of males compared to females. This is the first study to test effects of all 37 genes in the mitochondrial genome -- genes that copepods and humans share. The study found that males demonstrate more activity across all protein-coding mitochondrial genes than females. Although the study looks at tiny marine organisms called copepods, the findings have weighty implications for human medicine.

Researchers engineer AI path to prevent power outages      (via sciencedaily.com)     Original source 

Researchers developed an artificial intelligence (AI) model that could help electrical grids prevent power outages by automatically rerouting electricity in milliseconds. The approach is an early example of 'self-healing grid' technology, which uses AI to detect and repair problems such as outages autonomously and without human intervention when issues occur, such as storm-damaged power lines.

How cells boost gene expression      (via sciencedaily.com)     Original source 

The function of non-coding RNA in the cell has long been a mystery to researchers. Unlike coding RNA, non-coding RNA does not produce proteins -- yet it exists in large quantities. A research team has now discovered an important function of antisense RNA (asRNA): the researchers found that asRNA acts as a 'superhighway' in cell transport and thus accelerates gene expression.
