This paper proposes simple equations to predict the minimum oil film thickness and its position in reciprocating contacts, in good agreement with experimental data. The equations enable easy estimation of oil film thickness variation throughout the contact using operating conditions.
Researchers identify seven-gene signature in eccDNA that predicts LUAD recurrence risk. eccDNA features provide new prognostic insights into lung adenocarcinoma.
A new study found that certain carp species, such as goldfish and silver carp, are resistant to the devastating Koi herpesvirus (CyHV-3) and do not easily transmit it to common carp. This discovery offers a hopeful perspective on managing the disease in fish farms and freshwater ecosystems.
Researchers found that triploid loquats accumulate highly unsaturated phosphatidylcholine to stabilize cellular membranes during freezing. The EjFAD2 gene and its regulator EjMYBS3 transcription factor play a crucial role in this process, enabling the plants to maintain photosynthesis and survive cold more effectively.
A study in Horticulture Research reveals a coordinated scent-making network in herbaceous peony, involving terpene synthase, Nudix hydrolase, and prenyltransferase pathways. The research identifies dominant scent compounds and candidate enzymes, providing practical genetic targets for improving fragrance in ornamental breeding.
Recent research found that D-serine accelerates gastric cancer growth by suppressing cytotoxic T-cell activity and promoting immunosuppressive macrophages. High serum D-serine concentrations were linked to ICI therapy resistance in patients, suggesting its potential as a biomarker for disease progression.
A study found a significant decrease in postoperative endophthalmitis rates after implementing a multifaceted surgical safety culture intervention, from 0.038% to 0.013%. The rate dropped by 64.4% among patients undergoing inpatient ophthalmic surgery.
A study published in Advances in Atmospheric Sciences reveals that persistent ocean warming in the South Pacific during 2023-2024 was driven by two consecutive anomalous anticyclones over the region. The warming signal extended to depths of about 1000 m, leading to record-high sea surface temperatures and upper-2000-m ocean heat content.
A genetic switch LpCbDR1 in perennial ryegrass coordinates leaf yellowing, senescence timing, and drought tolerance by activating genes promoting chlorophyll breakdown and stress tolerance. This discovery offers a precise route for breeding more resilient grasses.
New research highlights the importance of preserving traditional cattle breeds' unique genetic profiles for resilience against disease and environmental challenges. These populations carry irreplaceable traits that could help future generations of farmers respond to global challenges such as climate change.
Research reveals how dogs developed specialized forms in response to human needs, such as compact sled dogs for Arctic regions and lean hunting dogs for tropical forests. Genetic adaptations also emerged to cope with oxygen-poor air at high altitudes, mirroring human populations' genetic traits.
