Towards non-toxic antifouling agents: A novel method for total synthesis of scabrolide F      (via sciencedaily.com)     Original source 

Norcembranolide diterpenes, isolated from the soft corals of the genus Sinularia, are important compounds for the development of new drugs, owing to their diverse biological activities. However, total synthesis methods for these compounds are scarce. Now, a team of researchers has achieved the total synthesis of scabrolide F, a norcembranolide diterpene. They also revealed its non-toxic antifouling properties. This novel method can lead to the development of new drugs and antifouling agents.

Revealing the dynamic choreography inside multilayer vesicles      (via sciencedaily.com)     Original source 

Our cells and the machinery inside them are engaged in a constant dance. This dance involves some surprisingly complicated choreography within the lipid bilayers that comprise cell membranes and vesicles -- structures that transport waste or food within cells. In a recent paper, researchers shed some light on how these vesicles self-assemble, knowledge that could help scientists design bio-inspired vesicles for drug-delivery or inspire them to create life-like synthetic materials.

Rewriting the armadillo family tree: A new species, plus a name change for the state mammal of Texas      (via sciencedaily.com)     Original source 

The nine-banded armadillo, which ranges all the way from Argentina to Nebraska, is actually four separate species. One of the species, the Guianan long-nosed armadillo, is new to science. Meanwhile, the species that has migrated from Mexico to the United States (and is the official small mammal of Texas) is now called the Mexican long-nosed armadillo.

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.

'A hearty debate' concludes plant-based meat alternatives are healthier for your heart than meat      (via sciencedaily.com)     Original source 

Even though there is substantial variability in the contents and nutritional profiles of plant-based meat alternatives (PBMAs), the nutritional profiles tend to reflect a heart-healthy dietary pattern. A review article of the available studies directly comparing the impact of plant-based and animal-based meats consistently suggests that the plant-based alternatives improve cardiovascular risk factors.

Wildfires increasingly threaten oil and gas drill sites, compounding potential health risks      (via sciencedaily.com)     Original source 

More than 100,000 oil and gas wells across the western U.S. are in areas burned by wildfires in recent decades, a new study has found, and some 3 million people live next to wells that in the future could be in the path of fires worsened by climate change.

Robots face the future      (via sciencedaily.com)     Original source 

Researchers have found a way to bind engineered skin tissue to the complex forms of humanoid robots. This brings with it potential benefits to robotic platforms such as increased mobility, self-healing abilities, embedded sensing capabilities and an increasingly lifelike appearance. Taking inspiration from human skin ligaments, the team included special perforations in a robot face, which helped a layer of skin take hold.

3D-printed chip sensor detects foodborne pathogens for safer products      (via sciencedaily.com)     Original source 

Researchers have developed a new method for detecting foodborne pathogens that is faster, cheaper, and more effective than existing methods. Their microfluidic chip uses light to detect multiple types of pathogens simultaneously and is created using 3D printing, making it easy to fabricate in large amounts and modify to target specific pathogens. The researchers hope their technique can improve screening processes and keep contaminated food out of the hands of consumers.

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.
