The single-atom-kernelled nanocluster catalyst obtained in "anti-galvanic reaction" for carbon dioxide conversion

Scientists have developed a novel single-atom-kernelled nanocluster catalyst that enhances the efficiency of carbon dioxide conversion. The catalyst, obtained through an 'anti-galvanic reaction' method, shows improved catalytic activity and selectivity compared to traditional methods.

Scientists create a DNA test that identifies Lyme disease in horses

A Rutgers scientist has developed a highly sensitive DNA test that can detect Lyme disease in horses, a condition that can cause long-term complications. The test, called genomic hybrid capture assay, was tested on a sick horse and successfully identified the pathogen, allowing for early diagnosis and treatment.

Scientists relieved to discover ‘curious’ creature with no anus is not earliest human ancestor

Scientists have discovered that Saccorhytus, a microscopic creature thought to be an early human ancestor, is actually part of a different family tree. The analysis revealed complex spines around its mouth and a lack of anus, indicating it is an ecdysoszoan, a group containing arthropods and nematodes.

Misophonia is more than just hating the sound of chewing

Research identified distinct brain connections in individuals with misophonia, revealing that it may not be solely linked to oral sensory processing. The study found stronger connections between regions associated with finger movement and sensation, as well as the insula area linked to strong emotions like disgust.

How hepatitis E tricks the immune system

Researchers discovered a mutated form of the hepatitis E virus that produces non-infectious particles but can bind antibodies, potentially giving the virus an advantage. The study found that one mutation affects the capsid protein and leads to smaller, non-infectious particles that are correctly recognized by the immune system.

Smartphone video motion analysis detected narrowed neck arteries that may lead to stroke

A new study published in the Journal of the American Heart Association suggests that smartphone video motion analysis can accurately detect narrowed neck arteries, which are a significant risk factor for stroke. The algorithm achieved an impressive 87% accuracy rate in detecting stenosis in participants with carotid artery disease.

How young chickens play can indicate how they feel

Researchers mapped young chickens' play development from hatching, finding 14 types of play that increased in intensity around 6-7 weeks old. Domestication didn't change play behavior, but tame chickens played more than their ancestors. Early stress surprisingly increased playful behavior.

Burying short sections of power lines would drastically reduce hurricanes’ future impact on coastal residents

Researchers at Princeton University found that burying 5% of power lines near main distribution points could reduce the number of affected residents by half. The study used Harris County, Texas, as an example and estimated that the risk of hurricane-blackout-heat wave events would increase 23 times by the end of the century under a

Oncotarget | Kinase activity in renal cell carcinoma, benign renal tissue and in response to tyrosine kinase inhibitors

Researchers identified differences in PTK activity between normal and cancer kidney tissue, with Src family kinases and PI3K pathways exhibiting high activity. Ex vivo treatment of clear cell RCC with TKIs revealed that tivozanib and cabozantinib were more potent inhibitors than sunitinib or pazopanib.

Lungless salamanders develop lungs as embryos despite lung loss in adults for millions of years

A new study reveals that four living amphibian clades, including the dominant Plethodontidae family of lungless salamanders, develop lungs as embryos but lose them as adults. This finding sheds light on the evolution of lung loss over millions of years and suggests that losing lungs may have enabled their remarkable evolutionary success.

Sea secrets surface in the Great Australian Bight

Oceanographers have discovered substantial subsurface phytoplankton layers deep beneath the eastern part of the Great Australian Bight, supporting rich marine biodiversity. This finding explains how the region's productivity survives even when surface phytoplankton blooms disappear during certain upwelling seasons.
