Researchers used microscopy to study neuron growth in Caenorhabditis elegans and found that certain neurons work backward from their destination. The discovery suggests that the brain is wired based on connectivity rather than absolute distance, providing an explanation for how the brain grows in proportion to the organism.
New Brown University research suggests nicotine interferes with multiple cellular interactions, potentially developing new treatments for various diseases. The study identified 55 proteins interacting with the alpha-7 nicotinic receptor, which may have broader roles in the body than previously thought.
Researchers found that considering partner characteristics together is the strongest predictor for STDs. Adding simple questions about partner characteristics to STD screenings could help catch more patients who need testing and education.
A novel digital gene-expression profiling technique is gaining traction, offering a fully quantitative approach to gene-expression analysis. The method has been shown to provide robust and comparable expression profiling data, making it an attractive alternative to traditional microarray-based platforms.
The University of Bath will use the funding to launch spin-off companies and influence government policy through its research, aiming to enhance business-academia partnerships. The £44 million Knowledge Transfer programme aims to reduce barriers between businesses and academia.
A team of researchers from Massachusetts General Hospital has found evidence of cell-to-cell communication by amino acids, leading to faster recovery of hepatocyte activity. The study reveals that proline, a building block of collagen, plays a key role in this process.
A study found that periodontal disease caused by Porphyromonas gingivalis can reactivate latent HIV-1 in infected individuals. The bacteria induce histone acetylation, leading to HIV-1 reactivation. Maintaining oral hygiene is crucial for preventing AIDS progression.
A study found that parents with low income, limited education, and single status experience higher levels of stress, which increases the likelihood of their children developing tooth decay. Conversely, receiving treatment for a child's dental decay can decrease parental stress levels.
Research by Yale University reveals that bird feathers create bright colors through nanostructures resembling a sponge with air bubbles. The structures self-assemble as the feather grows, replacing water bubbles with air, and have significant implications for the role of color in birds' plumage.
Physicians can reduce radiation exposure by using tube current modulation in 'triple rule-out' coronary CT angiography. This technique reduces effective radiation doses from 9.9-31.3 mSv to 5.4-16.6 mSv, comparable image quality and less than nuclear stress test radiation.
A Norwegian Institute of Public Health study analyzed children's diets combined with psychological and sociodemographic variables in mothers. The results show that mothers with high negative affectivity are more likely to give their children unhealthy food, but not the opposite for healthy food.
Researchers found that allergens can bind to and travel through the epithelium of allergic patients but not healthy subjects. This transport mechanism is crucial for the development of allergic reactions.
Researchers found that dopamine neuron bursting activity is crucial for learning rewarding outcomes. The study suggests that the NMDA receptor plays a key role in regulating burst firing in dopamine neurons.
The project aims to create a Medicago HapMap, mapping the genetic variations in the legume to reveal which genome regions control symbiosis and other legume-specific traits. Legumes are a crucial source of dietary protein and environmentally-friendly fertilizer, providing millions of tons of nitrogen to plants.
Researchers at Penn have identified a fluorescent anesthetic compound, 1-aminoanthracene (1-AMA), that allows for precise imaging of anesthetics in the body. This new tool enables high-throughput screening of novel anesthetic compounds, which could lead to safer and more effective drugs.
Researchers at the University of Pennsylvania have found a new way to combat malaria by trapping parasites inside host cells. They identified an enzyme called calpain-1, which parasites use to break out of infected cells, and developed a method to block it, leaving parasites trapped.
A new study from the Sahlgrenska Academy reveals that big men are more susceptible to atrial fibrillation, a disturbance in the heart's rhythm. The risk of atrial fibrillation increases linearly with both body size and weight gain, putting larger men at higher risk.
A recent study by NYU researchers found that sports drinks can cause tooth erosion and hypersensitivity due to high levels of citric acid. The condition affects one in 15 Americans and can lead to severe tooth damage if left untreated.
New research suggests Titan, Saturn's largest moon, has a subterranean ocean of hydrocarbons and unusual topography, including mountains with lower elevations than surrounding plains. The findings may help explain the presence of large lakes of hydrocarbons at both poles.
The analysis reveals highly polarised gamma rays, providing insight into the central engine's magnetic field structure. The team favours a synchrotron model, suggesting that the jet lifted the magnetic field into space.
Researchers at Duke University have identified a receptor on human glioblastoma cells that may be an appropriate target for therapies. Activation of the neurokinin 1 receptor leads to increased cell growth, but blocking this activity can reduce cell death and potentially stall cancer growth.
Physicists at the University of Leeds and IBM Research have made advances in racetrack memory, a new kind of computer memory that could replace hard disks. The technology is estimated to be 100 times cheaper per bit than flash memory and promises faster speeds.
Scientists have re-examined Hawaii's formation, finding the Pacific oceanic plate moved under a drifting hotspot, creating a 50 million-year-old bend in the seamount chain. Mantel circulation models aid understanding of forces on tectonic plates and stress estimation for major earthquakes.
Researchers from Regenstrief Institute have developed a technology that allows public health officials to send instant alerts to doctors and hospitals using an existing clinical messaging service. This approach minimizes delays in notification, which can be critical in disease outbreak response.
A novel compound called azelaic acid has been identified as a primer for the plant's immune system, leading to increased systemic plant immunity and disease resistance. The discovery was made by researchers at Oak Ridge National Laboratory and the University of Chicago.
Researchers create 'composite doublers' that take stress from joints and allow it to pass through without stressing the structure, extending its lifespan. The technology also serves as a warning system for inspectors and road workers when it begins to wear out.
A study at the University of Erlangen found that reducing tube voltage from 120 kV to 100 kV lowered cardiac CT radiation doses in adult patients weighing 185 pounds or less by 39% without compromising image quality. The lower dose resulted in effective radiation doses ranging from 4.9 to 11.9 mSv, compared to 8.8 to 16.9 mSv at 120 kV.
A computer-based model has been developed to aid radiologists in diagnosing breast cancer by analyzing mammogram images. The model was trained on 48,744 mammograms and found that it could detect 41 more cancers than routine practice, with potential benefits including reduced unnecessary biopsies.
