Researchers developed a way to control polymer molecule shape, leading to non-spherical nanoparticles that can encapsulate drugs. These natural-shaped plastic nanoparticles have shown preliminary evidence of entering tumor cells more easily than spherical ones.
A new law in Rhode Island requires coverage for fertility preservation prior to gonadotoxic medical therapy. The authors of the perspective published in NEJM recommend revising existing non-infertility-related mandates or establishing a separate definition for fertility preservation, which could encourage other states to follow suit.
Scientists used gold nanoparticles with molybdenum disulfide to study strain occurring when a semiconductor contacts a conductor at the nanoscale. They demonstrated localized strain of 1.4% using Tip-Enhanced Raman Spectroscopy, a unique technology that combines optical and atomic force microscopy.
Researcher suggests a wide range of animal species exhibit executive control when making decisions, consciously considering their goals and ways to satisfy them. Studies have shown that elephants, chimpanzees, ravens, and lions engage in rational decision-making, remembering specific events, using tools, and solving problems.
A recent Vanderbilt University Medical Center study found that combination therapy with azithromycin is unnecessary in most cases of pediatric pneumonia. The study of 1418 children showed no significant differences in outcomes between patients treated with a single antibiotic versus a combination of antibiotics. The researchers argue t...
Patients with advanced breast cancer who experience delayed disease progression have better quality of life outcomes compared to those whose disease progresses earlier. Delaying progression could be critical in improving health-related quality of life for patients with oestrogen receptor positive, HER2 negative advanced breast cancer.
A team of researchers, led by Luke Premo, question the widely accepted timeline of human cultural transmission, suggesting that it may be much more recent. They propose that the Oldowan tool, believed to be one of the first stone tools made by humans, could have been learned through innate skill rather than cultural transmission.
The study found that Laos' elephant population, which has dropped by half in the last 30 years, depends heavily on socio-economic practices. Implementing a 'maternity-leave' system for owners could help offset losses and promote breeding, potentially saving the species.
A recent study published in Frontiers in Psychology found that empowered employees are more proactive even when they don't trust their leader. This is because empowering leadership increases role breadth self-efficacy, allowing subordinates to take on new tasks and exhibit proactivity.
A national study by CU & Duke finds that transferring one embryo during IVF doubles the chance of a healthy baby. Fresh donor eggs provide a higher chance of implantation compared to frozen eggs.
A recent proposal to reorganize the traditional dinosaur family tree has sparked debate among experts. However, a new analysis by an international consortium found that the current model of an Ornithischia-Saurischia split remains supported, albeit with weak evidence for an alternative arrangement.
A large survey of breast cancer patients found that nearly one-third went against their doctor's advice and chose not to complete recommended adjuvant anti-cancer therapy. Patients with higher distrust in the healthcare system were more likely to report noncompliance, highlighting the need for strategies beyond boosting physician trust.
A new study found that most antibiotics decrease bacterial motility in multidrug-resistant Salmonella, but kanamycin increased swarming in one strain. Researchers hope to identify the accessory genes responsible for this effect to inform antibiotic choice.
Climate change poses a major threat to desert wildlife in central Australia, with feral animals such as cats and foxes exacerbating the issue. Removing introduced predators could boost rodent populations by nearly one in 10, according to new research from the University of Sydney.
A new study by Oregon State University shows that Brazil's environmental land registration program has slowed down deforestation on private land, particularly in the Amazon region. The CAR (Cadastro Ambiental Rural) system allows landowners to demonstrate compliance with regulations and provides a mechanism for government monitoring.
Researchers at George Washington University will follow children with autism through adolescence and into adulthood to understand differences in ASD risk between boys and girls. The study aims to identify biomarkers of developmental pathways that might differ for boys and girls, and generate insights on how to further explore the data.
Researchers developed a single-step, laser-based method to produce hybrid microstructures of silver and silicone. These structures exhibit both electrical conductivity and flexibility, making them suitable for sensing mechanical forces and enabling new types of optical and electrical devices.
Research finds that late preterm babies, born at 35 weeks, are more likely to develop altered heart control and increased cardiovascular disease risk. Adult premature males also show decreased blood pressure regulation.
A study found that people who can easily taste salt have differing amounts of salivary proteins than those who are less sensitive. This could lead to the development of more palatable low-sodium foods.
