The review highlights how macrophages, Th17 cells, and regulatory T cells shift across disease phases, and how metabolic reprogramming intervenes. Persistent injury disrupts this balance, leading to chronic pancreatitis.
Researchers investigate how warming oceans affect marine food webs by analyzing copepod diet differences. The study reveals geographical variations in basal diets, with tropical and subtropical regions favoring bacterial and heterotrophic bacteria, while colder regions prefer eukaryotic microalgae.
Researchers at Linköping University developed an organ-on-chip model of head and neck cancer, demonstrating how tumours interact with surrounding structures and tissues. The model showed that cancer cells respond differently to the ECM material and blood vessels, and that nerves can influence tumour behaviour and pain.
A 75-year dataset reveals a stark continental divide in El Niño impacts, with Southern Brazil facing torrential rainfall and the North experiencing severe drought. Month-by-month planning can help target preparedness efforts and reduce vulnerability.
A systematic review emphasizes the need for emotional security, family relationships, and culturally sensitive support for children approaching the end of life. The review found that children's spiritual concerns and needs for connection with others are often overlooked.
A study published in Advanced Science reveals that TREM2+ macrophages contribute to immune dysfunction in endometriosis, compromising CD8+ T cell and NK cell cytotoxic behavior. Researchers identified TREM2 as a potential therapeutic target, suggesting new avenues for developing non-hormonal therapies for endometriosis.
Research from Osaka Metropolitan University reveals that climate change is affecting Japan's forests, leading to changes in tree composition and structure. The study found that warmer temperatures and increased precipitation are driving the decline of cold-adapted tree species and the rise of warmer-adapted species.
Dr. Egan shares crucial steps to prevent foodborne illnesses, including handwashing, proper cooking techniques, and handling raw poultry. He emphasizes the importance of vigilance and taking responsibility for protecting loved ones during the holiday season.
A new study identifies a mechanism in the environment surrounding tumors that drives the growth of triple-negative breast cancer, a particularly challenging cancer to treat. Researchers found that a type of microRNA transferred from fibroblasts surrounding tumors, miR-1290, promotes cancer cell proliferation by suppressing tumor growth.
A study finds a direct link between reduced winter sea ice in the Barents and Kara Seas and summer droughts in eastern Europe and central Asia. The researchers used historical records of sea ice and atmospheric conditions to find a mechanistic link between winter sea ice cover and summer drought risk.
Researchers discovered a unique symbiotic bacterium, Candidatus Abyssoplasma scotoplanesicola, in deep-sea sea pigs. The bacterium has a minimized genome but produces 'giant' proteins, which likely play a role in interactions with host tissues or bacterial aggregation.
A study found that metformin kills cancer cells by blocking a mitochondrial-cytosolic circuit that drains surplus NADH, reducing reductive stress. The circuit, involving pyruvate carboxylase, mitochondrial malate dehydrogenase, and malic enzyme 1, is a key player in cancer cells' ability to survive under metabolic stress.
Researchers demonstrate that sound alone can recreate the experience of hand movement in flowing water, with increased pitch enhancing resistance. The study's findings may inform the development of sound-based technologies for visually impaired individuals, providing an alternative to visual cues.
Researchers review post-translational modifications of p53, revealing a dynamic signaling hub that coordinates cell-cycle arrest, apoptosis, and DNA repair. Targeting p53 PTM regulatory networks may offer anti-tumor strategies, but multiple obstacles limit clinical implementation.
Researchers at NUS developed a catalyst-regeneration strategy to improve hydrogen production from ammonia. The new catalyst, Pt/Fe-NC, resisted oxidation and poisoning, sustaining production for over 2,000 hours. This breakthrough brings ammonia-based hydrogen production closer to practical applications.
A systematic review and meta-analysis of 40 studies found that people with type 2 diabetes are 53% more likely to develop Alzheimer's disease. The review estimated that 4.7 out of 1000 people with type 2 diabetes will develop Alzheimer's in a year.
Professor Hanjung Lee's new monograph introduces an innovative approach to linguistic meaning study, integrating AI with linguistic theory. The book reveals AI language models' systematic tendencies to favor more frequent meanings, potentially distorting semantic variation found in actual language use.
A new study reveals that the decline in thermogenic fat activity with age may explain why older people feel the cold more. The research suggests that restoring thermogenic fat activity could help understand and treat age-related metabolic problems, including obesity and type 2 diabetes.
A study from the University of Birmingham found that nearly 30% of ingested carbohydrates remain unavailable to fuel exercise in hot conditions. Despite heat acclimation, the mechanism stopping carbohydrate transfer into muscles was not alleviated.
The study found that a salt-triggered gel containing engineered Salmonella reduced tumour growth by shrinking tumours as well as free bacteria, cutting weight loss by 82% and reversing liver and spleen damage. The gel also delivered the bacteria to the tumours, avoiding poisoning, and showed promise in treating melanoma and other cancers.
Researchers develop flexible coating with microscopic cracks that amplify antibacterial power, killing 80% of bacteria within three hours. The coating, combined with electrical stimulation, creates an antimicrobial response that can be switched on when needed.
Pseudogenes contribute to the adaptation of vertebrates to new environments by inactivating genes that are no longer necessary. This process, known as pseudogenization, has been observed in whales, naked mole-rats, and hummingbirds, where it has helped these species thrive in different ecological niches. For example, the loss of the TL...
Urban green-up dates advance faster than rural green-up in 80.4% of Chinese cities, with cities pulling ahead by 0.37 days a year. Heat requirement, not warming, governs the urban-rural disparity in spring phenology advancement.
