However, reforms like scoop protection can help mitigate this issue. To further improve science, measures like preregistration and criticism of research plans can encourage ...
Researchers at Chalmers University of Technology have found that genetic motifs, patterns and combinations of DNA's molecular building blocks, determine the quantity of gene expression. This discovery, using supercomputers and AI, could shed new light on cancer and improve pharmaceutical development.
Scientists at US national laboratories develop a new state-of-the-art half-meter-long prototype magnet that meets requirements for use in existing and future light source facilities. The design offers nearly twice the current capacity with a higher magnetic field, enabling significant improvements in efficiency and cost savings.
The NRG Oncology trial shows improved in-field tumor control with adaptive radiotherapy, increasing local-regional tumor control by 11% and primary tumor control by 17%. The study's results suggest individualizing radiotherapy dose prescriptions according to patient's intrinsic sensitivity for better survival outcomes.
Research by Michigan State University finds that livestock workers are at high risk of acquiring antibiotic-resistant bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). The study highlights the importance of good hygiene practices and policies in minimizing the spread of livestock-associated MRSA.
A new study from the University of Colorado Boulder reveals that the ocean's surface layer is becoming shallower, making it easier to warm and increasing the likelihood of extreme marine heatwaves. This thinning can lead to drastic swings in ocean temperatures, threatening sensitive marine ecosystems.
