Traditional medicine plant could combat drug-resistant malaria      (via sciencedaily.com)     Original source 

Much of what is now considered modern medicine originated as folk remedies or traditional, Indigenous practices. These customs are still alive today, and they could help address a variety of conditions. Now, researchers have identified compounds in the leaves of a particular medicinal Labrador tea plant used throughout the First Nations of Nunavik, Canada, and demonstrated that one of them has activity against the parasite responsible for malaria.

How bacteria evolve resistance to antibiotics      (via sciencedaily.com)     Original source 

Bacteria can rapidly evolve resistance to antibiotics by adapting special pumps to flush them out of their cells, according to new research. Antimicrobial resistance is a growing problem of global significance. The rise of resistant 'superbugs' threatens our ability to use antimicrobials like antibiotics to treat and prevent the spread of infections caused by microorganisms. It is hoped that the findings will improve how antibiotics are used to help prevent further spread of antimicrobial resistance.

Like ancient mariners, ancestors of Prochlorococcus microbes rode out to sea on exoskeleton particles      (via sciencedaily.com)     Original source 

Throughout the ocean, billions upon billions of plant-like microbes make up an invisible floating forest. As they drift, the tiny organisms use sunlight to suck up carbon dioxide from the atmosphere. Collectively, these photosynthesizing plankton, or phytoplankton, absorb almost as much CO2 as the world’s terrestrial forests. A measurable fraction of their carbon-capturing muscle comes from Prochlorococcus — an emerald-tinged free-floater that is the most abundant phytoplankton in the oceans today. New research suggests the microbe's ancient coastal ancestors colonized the ocean by rafting out on chitin particles.

How life and geology worked together to forge Earth's nutrient rich crust      (via sciencedaily.com)     Original source 

Around 500 million years ago life in the oceans rapidly diversified. In the blink of an eye -- at least in geological terms -- life transformed from simple, soft-bodied creatures to complex multicellular organisms with shells and skeletons. Now, research has shown that the diversification of life at this time also led to a drastic change in the chemistry of Earth's crust -- the uppermost layer we walk on and, crucially, the layer which provides many of the nutrients essential to life.

Unlocking the power of photosynthesis for clean energy production      (via sciencedaily.com)     Original source 

Researchers are embarking on a groundbreaking project to mimic the natural process of photosynthesis using bacteria to deliver electrons to a nanocrystal semiconductor photocatalyst. By leveraging the unique properties of microorganisms and nanomaterials, the system has the potential to replace current approaches that derive hydrogen from fossil fuels, revolutionizing the way hydrogen fuel is produced and unlocking a powerful source of renewable energy.

A journey to the origins of multicellular life: Long-term experimental evolution in the lab      (via sciencedaily.com)     Original source 

Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how snowflake yeast evolved to be physically stronger and more than 20,000 times larger than their ancestor. Their study is the first major report on the ongoing Multicellularity Long-Term Evolution Experiment (MuLTEE), which the team hopes to run for decades.

Fecal microbiota transplants: Two reviews explore what's worked, what hasn't, and where do we go from here      (via sciencedaily.com)     Original source 

Fecal microbiota transplants are the most effective and affordable treatment for recurrent infections with Clostridioides difficile, an opportunistic bacterium and the most common cause of hospital-acquired intestinal infections. However, attempts to treat chronic noncommunicable diseases such as ulcerative colitis and metabolic syndrome via fecal microbiota transplantation (FMT) have yielded mixed results.

Crops evolved by swapping genetic modules between cells      (via sciencedaily.com)     Original source 

Comparing individual cells across corn, sorghum, and millet reveals evolutionary differences among these important cereal crops, according to a new study. The findings bring researchers closer to pinpointing which genes control important agricultural traits such as drought tolerance, which will help scientists faced with a changing climate adapt crops to drier environments.

African rhinos share retroviruses not found in Asian rhinos or other related species      (via sciencedaily.com)     Original source 

Rhinoceros belong to a mammalian order called odd-toed ungulates that also include horses and tapirs. They are found in Africa and Asia. Until recently, evidence suggested that throughout their evolutionary history, gamma-retroviruses such as Murine leukemia virus had not colonized their genomes, unlike most other mammalian orders. The colonization process is called retroviral endogenization and has resulted in most mammalian genomes being comprised of up to ten percent retroviral like sequences.

Extending the life of a lithium metal anode using a protective layer made of an extremely tough gel electrolyte      (via sciencedaily.com)     Original source 

A research team has succeeded in substantially improving the cycling performance of a lithium metal battery by developing a mechanically very strong polymeric gel electrolyte and integrating it into the battery as a layer to protect the lithium metal anode. This achievement may greatly facilitate efforts to put lithium metal anodes -- a potentially very high performance anode material -- into practical use.

Basic 'toolkit' for organ development is illuminated by sea star      (via sciencedaily.com)     Original source 

One of the basic and crucial embryonic processes to unfold in virtually every living organism is the formation of hollow, tubular structures that go on to form blood vessels or a digestive tract, and through branching and differentiation, complex organs including the heart and kidneys. This study illuminates fundamental design principles of tubulogenesis for all chordates, including mammals.
