A study found that 12% of recurrent ductal carcinoma in situ (DCIS) cases were new primary lesions unrelated to the original tumor. These findings suggest that genetic biomarkers for predicting recurrence may not be effective for all patients.
A new Raman spectroscopy system allows for real-time molecular imaging of near-surface tissue, providing detailed biochemical distributions for disease tissue differentiation. The technique offers high spatial resolution and can be used for clinical diagnostics and molecular boundary demarcation.
Researchers discovered that the CuO2 planes in superconducting Pr2Ba4Cu7O15-δ are both insulating and antiferromagnetic. The findings contradict previous theories and suggest that double chains may be responsible for the superconductivity.
A new study found that less than half of clinical trials reported race/ethnicity data, with minorities underrepresented despite efforts to increase diversity. Industry-funded studies had the greatest gaps in enrolling minority participants.
Scientists have discovered a novel protein NDB1 that inactivates MYB1, a key regulator of nitrogen assimilation in plants. This finding could lead to improved biomass production and crop yields by manipulating NDB1. Researchers are now exploring the potential to boost plant growth through NDB1 manipulation.
A study found that trainee teachers who received AI-generated feedback improved their diagnostic reasoning, identifying potential learning difficulties in pupils more accurately. The AI system analyzed the trainees' work and provided clear, adaptive feedback.
A new strain of algae has been identified that can produce green hydrogen gas via photosynthesis on an industrial scale. This breakthrough could accelerate the transition to environmentally friendly green hydrogen and reduce pollution. The researchers also plan to develop methods to increase production rates and reduce costs.
Researchers at Flinders University found that sharks can learn to avoid wasting time and energy on inaccessible food sources. The study, published in Animal Behaviour, reveals the decline of shark's natural response to prey when reward frequency is decreased or non-existent.
Researchers developed a new treatment option for relapsed or refractory CD30+ lymphoma using natural killer cells complexed with a CD30/CD16A bispecific antibody. The treatment showed an overall response rate of 89% in patients with advanced lymphoma.
Tel Aviv University researchers develop innovative model that explains wave formation, tested in complex experiments. The model takes into account all unstable harmonics and limitations of previous models, providing high reliability for describing physical situation.
A new study reveals funding for fertility preservation policies varies across the UK, with Scotland offering the most inclusive approach. The study highlights the need for standardization of policies to ensure equal access to care for patients.
Scientists create microstructures that control light to display colors with high contrast using a novel additive manufacturing process. The team prints blue, green, yellow, and orange pictures on flexible substrates, including water bottles.
The CodeBreaK 100 trial demonstrated prolonged tumor responses and favorable safety profiles in patients treated with sotorasib. Long-term treatment was well-tolerated, with a two-year overall survival rate of 32.5%.
Researchers developed innovative smart sensors to test new vaccines, revealing significant discrepancies between subjective self-reports and objective measurements. The study found that side effects escalate over the first 48 hours and then stabilize, with parameters returning to pre-vaccination levels.
A new CAR T-cell product targeting CLDN6 showed acceptable safety and early signs of efficacy in a phase I/II clinical trial. The therapy combined with an mRNA vaccine expanded transferred CAR T cells and improved tumor cell killing.
Researchers developed a MOF-based system for delivering DNA into target cells, overcoming challenges in gene therapy. The tiny structures protected genetic cargo and helped ferry it into the nucleus, where gene activity takes place.
Researchers identified a genetic variant associated with increased response to anti-PD-1 therapy and higher immune-related side effects in lung cancer patients. The variant, found in 15.7% of exceptional responders, may be used to identify patients who would benefit from treatment.
Researchers developed a novel approach combining interference lithography and grayscale-patterned secondary exposure to create high-throughput nanopatterning on a wafer-scale area. This method enables precise control of feature sizes, overcoming challenges in mainstream approaches.
