A new paper presents findings about the Kuiper Belt Object 486958 Arrokoth, shedding new light on the preservation of volatile substances like carbon monoxide in such distant celestial bodies. The research uses Arrokoth as a case study to propose that many Kuiper Belt Objects -- remnants from the dawn of our solar system -- could still retain their original volatile ices, challenging previous notions about the evolutionary path of these...

The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed by the action of evaporating CO2 ice, according to a new study. Read more ›

A new method of timber analysis can confidently identify the location in which the tree was harvested. The method has been developed with the aim of combating illegal timber imports from Russia and Belarus. Read more ›

Researchers uncovered the mechanistic details behind how several proteins interact to help cells recognize and remove damaged mitochondria. Optineurin (OPTN) and its interactions are needed to provide a contact site for another protein, Tank-binding kinase 1 (TBK1), during this process. The OPTN-TBK1 relationship is necessary for these mitochondria to be recognized and eliminated from the cell. This mechanism may have relevance for developing drugs to treat Parkinson's disease.

Dairy cows receive a huge amount of care during their lives on a farm, but procedures, especially restraining during procedures, can be stressful for some animals. Positive reinforcement training -- or training with a reward to achieve a desired behavior -- has shown promise to reduce this fear in other species. Read more ›

New research has found that there is a direct socioeconomic impact of loneliness in early adolescence. The research found that lonely young adults are more likely to be out of education, employment, or training (NEET) and consider themselves less employable and lower on the economic ladder than their less lonely peers.

Carbon dioxide emissions are not typically associated with water ways, like streams and rivers, but emerging research shows that water bodies play an important role in storing and releasing carbon dioxide. As many states look for cost-effective ways to mitigate climate change, scientists looked at a way to optimize CO2 sensors to better measure carbon dioxide emissions in lotic, or moving, bodies of water offering a new tool that can...

An effective treatment for chronic wounds that does not involve antibiotics, but an ionised gas to activate a wound dressing, has been developed by a team of international scientists. Read more ›

To combine two low-energy photons into one high-energy photon efficiently, the energy must be able to hop freely, but not too quickly, between randomly oriented molecules of a solid. The discovery provides a much-needed design guideline for developing materials for more efficient PV cells, displays, or even anti-cancer therapies. Read more ›

U.S. veterans of the wars in Afghanistan and Iraq who suffered mild traumatic brain injury from exposure to explosive blasts were found to have changes in cerebrospinal fluid proteins that are typically seen in people who develop Alzheimer's disease, according to researchers. Read more ›

The origin of heavy elements in our universe is theorized to be the result of neutron star collisions, which produce conditions hot and dense enough for free neutrons to merge with atomic nuclei and form new elements in a split-second window of time. Testing this theory and answering other astrophysical questions requires predictions for a vast range of masses of atomic nuclei. Scientists are using machine learning algorithms to successfully...

Seattle may have experienced its own Swift Quake last July, but at an August 2023 concert Taylor Swift's fans in Los Angeles gave scientists a lot of shaking to ponder. After some debate, a research team concluded that it was likely the dancing and jumping motions of the audience at SoFi Stadium -- not the musical beats or reverberations of the sound system -- that generated the concert's distinct harmonic...

Repeats of DNA sequences, often referred to as 'junk DNA' or 'dark matter,' that are found in chromosomes and could contribute to cancer or other diseases have been challenging to identify and characterize. Now, researchers have developed a novel approach that uses machine learning to identify these elements in cancerous tissue, as well as in cell-free DNA (cfDNA) -- fragments that are shed from tumors and float in the bloodstream....

A new study shines a spotlight on sulfur, a chemical element that, while all familiar, has proved surprisingly resistant to scientific efforts in probing its role in the origin of life. Read more ›
