Illicit crops, particularly opium poppies, are expanding into critical bird habitats in the Andes region of Colombia. This could lead to devastating effects on forest-dependent bird species if the expansion continues.
Researchers engineered a virus to target prostate-specific antigen, appearing as 'hot spots' in primary tumors and distant metastases. This method could deliver toxic treatments directly to prostate cancer cells, killing them while sparing surrounding healthy tissue.
A study found that over half of children's Medicaid expenses are for injuries, with an average cost of $396 per child per year. The most common injury types were blunt force and penetrating trauma, often caused by falls.
Astronomers found that most comets disappear after their first pass through the solar system, but recent modelling suggests the number of dormant comets is far too low to accommodate predicted numbers. Dr Foot proposes mirror matter as a possible explanation for the missing comets.
Researchers have developed a new genetic shark-identification test that is quick, accurate and relatively cheap. The test has been evaluated on 33 closely-related known species and found to be nearly 100% accurate, with an average accuracy of over 99%, according to Shivji and his colleagues.
Researchers developed a new technique to analyze RNA splicing in yeast, revealing the complex process of gene expression. By studying yeast genes with DNA microarrays, they gained insights into alternative splicing and its role in human diseases.
Researchers tested the effectiveness of an electric barrier in preventing Asian carp from passing through a simulated barrier near Romeoville, Illinois. The study found that only one fish out of 381 attempts successfully passed through the barrier, and smaller fish were less susceptible to the electric current.
Researchers found that whitebark pines, large ranges, and low human density are key factors in the survival of grizzly bears. The ESA has helped protect these areas, leading to increased bear populations in places like Yellowstone.
Researchers Katharina Lodders and her team found evidence of complex chemistry in brown dwarf atmospheres, including the formation of liquid iron clouds. The study revealed that as brown dwarfs cool, certain compounds reappear in their atmospheres.
Chicago researchers awarded $9 million NIH grant to investigate the impact of lifestyle experiences on cognitive function and Alzheimer's disease. The study aims to understand how cognitively stimulating activities can increase neural reserve and reduce the likelihood of memory loss and other clinical signs of Alzheimer's.
A team of researchers, government agencies, and private companies test a sustainable, environmentally friendly open ocean aquaculture industry in the Gulf of Mexico. The project utilizes innovative technologies, such as a single-point mooring system and automated innovations like a remote camera and satellite tracking system.
Researchers believe that lunar debris may hold fossils from Earth's early microbial life, with potential insights into the evolution of life on our planet. By studying this ancient material, scientists can gain a better understanding of the moon's role as a window into Earth's history.
Autistic children exhibit significantly increased cerebral volumes compared to typically developing children, suggesting abnormal brain development processes occur very early. Brain volume levels out to normal size by adolescence and adulthood.
Biomedical engineer Shelly Sakiyama-Elbert has designed a novel nerve repair system that uses a gel-filled tube to deliver growth factor proteins stimulating nerve regeneration. The system promotes peripheral nerve regeneration in preliminary rat studies and shows promise for spinal cord repair.
A team of scholars discovered that early Maya centers were abandoned due to a drastic change in local environments, transforming swamp-like bajos into seasonal swamps. The study found evidence of human-induced environmental change and climatic shift, leading the Maya to adapt and thrive in the altered environment.
A review of medical savings accounts (MSAs) suggests they are unlikely to reduce healthcare spending while maintaining access to services for all Canadians. MSAs were assessed using data from Manitoba residents, and the results showed an increase in government spending on healthcare if the threshold was used as MSA entitlement.
Researchers used bat hibernation physiology to predict climate change effects, finding that warmer winters will allow little brown bats to expand their northern ranges. The study's findings highlight the importance of basic physiological processes in understanding ecosystem changes.
Research by James P. Smith and Dana P. Goldman found that education level is a significant factor in adherence to treatment regimens, particularly for complex diseases like HIV and diabetes. The study suggests that education can help improve health outcomes by promoting better adherence to treatment plans.
A new system is being developed to aid plastic surgeons in reconstructive surgery by analyzing faces using wavelet analysis, recommending procedures and assessing outcomes. This technology has potential applications outside of plastic surgery, including facial recognition and security, as well as quantifying beauty.
A study by Andrew Hansen and Jay Rotella found that development near nature reserves can harm bird populations, as many species rely on productive habitats outside the reserve. The researchers suggest that conserving population source areas outside reserves is necessary to protect biodiversity in nature reserves.
