Researchers successfully treated 42 individual kidney tumors using minimally invasive RFA, with all surface tumors completely destroyed. Patients with limited kidney function maintained good kidney function and had no local recurrence of the treated tumor.
A comprehensive study of 2,881 gay men in major US cities found that domestic violence is an equal opportunity epidemic, with HIV-positive individuals and younger men disproportionately affected. The research highlights the need for improved support systems and training for medical professionals to address male-male domestic violence.
Research finds that forest fragmentation leads to increased blacklegged tick populations, particularly in areas with small forest fragments. This could lead to a higher risk of Lyme disease for people living nearby, as these ticks are the primary carriers of the bacteria.
Research found significant species diversity in riparian areas, with up to 40 times more exotic species per plot compared to uplands. Flood frequency also impacts species richness, with decreased numbers of exotic species as flood frequency decreases.
Researchers found that school-forming goat fish synchronize their activity patterns to increase food catch. This synchronization strategy is effective even in chaotic systems, where individual behavior can vary wildly.
A study found that California's marine reserves cannot protect the state's low red abalone population from being overhunted by sea otters. The researchers suggest that single-use reserves focus on either ecosystem restoration or fishery development instead.
A study by Ohio State University found that topical oxygen therapy significantly improved healing rates for difficult-to-treat wounds, including diabetic hand ulcers and bedsores. The therapy, which involves applying pure oxygen to the wound, showed a 75% healing rate for acute traumatic injuries.
Researchers at Penn GSE will collaborate with city government and the school district to create the Kids' Integrated Database System, merging databases for over 250,000 Philadelphia children. The KIDS system aims to examine high-priority issues in early childhood development, including school readiness, foster care, and special education.
The study found that despite huge habitat losses, up to 90% of original crustacean diversity may still survive in the few remaining seasonal wetlands in Illinois. The researchers sampled 33 crustacean species from 13 ponds and estimated there could have been as many as 85 species originally.
The new flat motor can be configured in various formats, including a thin version that can drive changes in airplane wing camber or serve as the drive element in compact laptop computers. The prototype has reached high speeds and maximum torque of 0.4 Nm, with cost estimates as low as $10 for mass production.
Researchers found that female Mexican Spotted Owls spent 60% less time on prey-handling activities with high hiking intensity. The study recommends protecting owl habitat during the nesting season by limiting hiking or establishing buffers around nest sites.
The introduction of non-native species has accelerated invasions, with many becoming economically beneficial but ecologically destructive. Biocontrol methods are often ineffective and can harm native species.
Research shows that population stability and size tend to increase with community diversity, likely due to variation in local productivity. This finding challenges ecological theory, which predicts a decline in population stability as community diversity increases.
