The study used a YBCO bicrystal and transmission electron microscope to visualize the effects of calcium doping on grain boundaries, revealing a 35% increase in current flow.
Researchers found that a caterpillar's adaptation to a specific fruit's chemical composition allows it to survive without triggering the plant's defense mechanism, providing a stable food supply. This unique dietary preference also shields the caterpillar from parasites, enabling it to thrive in an otherwise hostile environment.
Researchers found that visual perception can stabilize in ambiguous conditions, independent of the memory of object identity. The mechanism underlying this stabilization is linked to the removal of local adaptation and depends on the stimulus location.
Two landmark studies show that Taxotere-based regimens improve patients' PSA responses by 43% and pain responses by 59%, leading to a 27% increase in disease-progression-free survival. The treatment also provides hope to thousands of men worldwide, offering an important new option for living longer.

The study also revealed younger African American women have fewer pregnancies and breastfed less often, which could lead to a rapid increase in breast cancer rates.
Researchers found that clinicians missed about half of symptoms reported by patients, and patients also missed about half of the symptoms recorded by physicians. The study suggests that new patient reporting tools should be developed for use in chemotherapy clinical trials to improve accuracy.
A retrospective study of 110 elderly leukemia patients found similar complete remission and two-year survival rates as younger patients when treated with anthracyclin-based induction chemotherapy. The study's findings suggest that age is not a predictor of survival, but rather the treatment protocol received.
