A study funded by Cargill Crop Nutrition found that varying nitrogen application rates can increase corn yield with similar or higher nitrogen rates, but may not improve grain quality. Researchers also discovered that one hybrid performed better than the other under both uniform and varied nitrogen applications.
Research reveals that children's cortisol levels are already high several months before the start of school term, suggesting an early anticipation of stress. Children with more extroverted personalities tend to experience higher stress levels and may benefit from support for parents' anxiety about school transition.
UWM researchers have devised a method for creating hybrid structures by coating CNTs with aerosol nanoparticles, producing low-cost
Researchers developed a blood-flow detector software to track changes in brain blood flow in real-time, showing promise in preventing brain damage and death. The system is designed for children with head injuries, offering potential lifesaving benefits.
Computer scientists at UC San Diego create a new algorithm to generate annotated Internet router graphs, mimicking key features of the Internet. The technique allows researchers to experiment with different network topologies and test the sensitivity of various techniques.
A recent study documents significant increases in El Salvador's wooded areas since the 1990s, driven by population movements and remittances. The research found that households receiving foreign funds felt less need to maintain existing fields, resulting in reduced land clearing and forest regrowth.
Researchers identified a region on chromosome 5p associated with dense breast tissue, a known risk factor for breast cancer. Women with dense breasts are three to five times more likely to develop breast cancer than those with less dense breasts.
A University of Florida study found that teenage girls who start dieting are twice as likely to begin smoking. Researchers analyzed the dieting and smoking practices of 8,000 adolescents and discovered that consistent dieters were more likely to smoke.
SMART-1 has mapped the polar regions, surveyed lunar resources, and investigated potential landing sites. The mission has provided clues on the dynamics of ejecta after impact and laboratory experiments have modeled impacts.
Researchers found that indoor concentrations of particulate pollution frequently exceeded standards for outdoor air, with high levels recorded in homes of patients with COPD. The study highlights the need for further research into the impact of indoor air quality on adults with COPD.
The University of Utah has been awarded a five-year, $19.2 million NIH grant to establish an HIV research center focusing on the structural biology of the virus. This research aims to understand how HIV takes control of host cells and develop new treatments.
Researchers developed a new technique that can detect specific chromosomal damage associated with lung cancer, which may indicate an increased risk. The study found significant differences in chromosomal abnormalities between never-smokers and high-risk smokers and patients with lung cancer.
A report reveals a significant decline in US Veteran Affairs (VA) reporting of new cancer cases to California registries, starting from 2004. This omission could introduce 'uncorrectable bias' in epidemiological studies and hamper efforts to identify quality-of-care issues for VA patients with cancer.
A new UCLA study found that up to one-fourth of HIV-positive patients in Los Angeles reported feeling stigmatized by their healthcare providers, leading to low access to care and delayed treatment. The perception of stigma was linked to higher odds of reporting low access to care, with significant consequences for patient outcomes.
Recent symposium discussions highlighted the brain's role in initiating and regulating obesity, as well as its response to nutrient abundance. Research suggests impaired brain function may contribute to weight gain and insulin resistance, fueling obesity and type 2 diabetes development.
Researchers at UAB found that resveratrol, a compound in red wine, reduces prostate cancer risk by 87% in male mice. The study also showed that resveratrol slows tumor growth in less-serious forms of prostate cancer.
A new study by the Society for Prevention Research reveals that many children are starting to drink alcohol as early as 4th grade. The survey data shows a concerning trend among 4th, 5th, and 6th graders who have already begun drinking.
As infants grow, their visual and auditory systems fine-tune to relevant distinctions, but also lose the ability to discriminate irrelevant stimuli. Environmental input helps refine these neural connections, enabling infants to better perceive salient inputs.
Researchers found that tDNA genes and components of RNA pol III are required for establishing silent chromatin cohesion at the HMR locus. This discovery provides new insights into chromosome architecture and may have implications for understanding genetic regulation.
A study by Dutch researchers identified four cases of bronchiolitis obliterans syndrome (BOS) among workers at a chemical plant producing diacetyl, a key component of butter flavoring. The findings support the conclusion that an agent in the diacetyl production process has caused BOS.
A recent study by UWM paleoecologist Margaret Fraiser suggests that elevated CO2 levels contributed to the Permian-Triassic mass extinction, with bivalves emerging as the only survivors. The research provides valuable insights into the impact of CO2 on marine ecosystems and could help scientists predict future oceanic changes.
The Centers for Medicare and Medicaid Services (CMS) has rejected a petition calling for strengthened standards for genetic testing laboratories, citing cost concerns. The decision prioritizes affordability over patient safety, despite reports of laboratory errors and inadequate proficiency testing.
Stevens Institute of Technology has received $164,000 to accelerate the commercialization of two technologies: an intelligent multi-network router/radio and a surveillance camera capable of detecting chemical and biological agents. The funding supports job creation and establishment of New Jersey as a model for homeland security.
Researchers studied crayfish brain function, discovering integration of sensory inputs from antennae, legs, and antennules for environmental awareness and hunting success. Crayfish use distinct senses to detect food, predators, and mates in their aquatic environment.
Researchers developed an improved dosing formula for warfarin that takes into account genetic variations in VKORC1 and CYP2C9 genes. This approach enables faster and more accurate estimation of the optimal warfarin dose, cutting dosage changes and potentially increasing patient safety.
The Wistar Institute's novel HIV vaccine has received funding for human clinical trials after demonstrating a vigorous immune response in preclinical studies. The vaccine uses a chimpanzee virus backbone and aims to stimulate CD8+ T cells, which can reduce viral load but not prevent infection.
