In new experiment, scientists record Earth's radio waves from the moon      (via sciencedaily.com)     Original source 

Odysseus, a tenacious lander built by the company Intuitive Machines, almost didn't make it to the moon. But an experiment aboard the spacecraft managed to capture an image of Earth as it might look to observers on a planet far from our own.

Changes Upstream: RIPE team uses CRISPR/Cas9 to alter photosynthesis for the first time      (via sciencedaily.com)     Original source 

Scientists used CRISPR/Cas9 to increase gene expression in rice by changing its upstream regulatory DNA. While other studies have used the technology to knock out or decrease the expression of genes, this study, is an unbiased gene-editing approach to increase gene expression and downstream photosynthetic activity. The approach is more difficult than transgenic breeding, but could potentially preempt regulatory issues by changing DNA already within the plant, allowing the plants to get in the hands of farmers sooner.

Fat molecule's inability to bond with shape-shifting protein in cell's powerhouse linked to an inherited metabolic disease      (via sciencedaily.com)     Original source 

By studying mutations in yeast and human cells, scientists say they have found that biochemical bonds between fats and proteins in the mitochondrion, the cell's powerhouse, play a crucial role in how our cells produce energy.

Mushroom stump waste could be inexpensive, healthy chicken feed supplement      (via sciencedaily.com)     Original source 

Feed costs for producing broiler chickens accounts for 60% to 70% of total production costs, and stump waste from the production of button mushrooms comprises nearly 30% of total mushroom weight. Marrying the two has the potential to reduce both cost and waste, especially in Pennsylvania, which is a national leader in the production of broiler chickens and button mushrooms.

Earth and space share the same turbulence      (via sciencedaily.com)     Original source 

Researchers have discovered that the turbulence found in the thermosphere -- known as the gateway to space -- and turbulence in the troposphere, here closer to sea level, follow the same physical laws despite having drastically different atmospheric compositions and dynamics.

Silkworms help grow better organ-like tissues in labs      (via sciencedaily.com)     Original source 

Biomedical engineers have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used in a kidney organ-on-a-chip platform, the membrane helped tissues grow to recreate the functionality of both healthy and diseased kidneys.

A new study reveals that marine cyanobacteria communicate      (via sciencedaily.com)     Original source 

A breakthrough study changes the way we understand cyanobacteria, which are essential for the sustenance of life. The study shows that these organisms do not operate in isolation, but rather physically interact through membrane-nanotubes, which function as exchange bridges between cells.

Determining sex in ants      (via sciencedaily.com)     Original source 

Researchers have been investigating the molecular mechanisms responsible for determining sex in ants. Although the vast majority of an ant colony consists of female workers, males are essential to the continuing survival of the species. In order to uncover the mechanisms involved, the researchers decided to focus on diploid males, which occasionally occur in the Argentine ant.

Novel lipopeptide proves lethal against Staphylococcus areus      (via sciencedaily.com)     Original source 

Researchers provide the first insight into the mode of action of the lipopeptide serrawettin W2-FL10, derived from Serratia marcescens. This lipopeptide targets the cell membrane of S. aureus, causing lesions which result in the leakage of intracellular components and ultimately cell death.

Exotic black holes could be a byproduct of dark matter      (via sciencedaily.com)     Original source 

In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose. The gravitational pull from these tiny, invisible objects could potentially explain all the dark matter that we can't see today.

Tropical forests adjust strategies to thrive even when soils are nutrient poor      (via sciencedaily.com)     Original source 

Tropical forests store a third of the world's carbon in their wood and soils. However, their future as a carbon sink has been uncertain. Scientists have long wondered whether nutrient-poor tropical soils would limit the ability of mature and recovering forests to thrive. A study offers a hopeful response, suggesting that forests have flexible strategies that help them overcome the challenge of scarce nutrients.

Planet-forming disks around very low-mass stars are different      (via sciencedaily.com)     Original source 

Using the James Webb Space Telescope, a team of astronomers studied the properties of a planet-forming disk around a young and very low-mass star. The results reveal the richest hydrocarbon composition seen to date in a protoplanetary disk, including the first extrasolar detection of ethane and a relatively low abundance of oxygen-bearing species. By including previous similar detections, this finding confirms a trend of disks around very low-mass stars to be chemically distinct from those around more massive stars like the Sun, influencing the atmospheres of planets forming there.

Researchers solve 2,000-year-old mystery of the shipworm      (via sciencedaily.com)     Original source 

They bedeviled ancient Greek navies, helped shipwreck Christopher Columbus, aided in the sinking of the Spanish Armada and caused the wharves in San Francisco Bay to collapse into the sea, but until now, scientists have been unable to pinpoint exactly how shipworms -- a family of mollusks -- are able to cause such damage. A team of researchers has discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the gut called the 'typhlosole,' have the ability to secrete the enzymes needed to digest lignin -- the toughest part of wood.
