NIST researchers Bo Yang and Vinod Tewary used a mathematical concept to predict how self-assembling quantum dots align themselves. The theory, based on the elastic energy release rate, can aid in developing more reliable methods for fabricating quantum dot devices.
Dr. Halas' nanoshell technology has the potential to revolutionize breast cancer detection and treatment by providing earlier diagnosis, increased imaging resolution, and real-time information about tumor cells. This innovative approach uses near infrared light to target and destroy tumors without harming healthy tissue.
Researchers have developed a miniature biolab on a silicon chip that captures DNA from samples, purifies it, and performs polymerase chain reaction to rapidly replicate the selected segment of DNA. This breakthrough simplifies the process and enables real-time automated detection of biological agents.
NIST scientists have developed a new tool in chemical sensing called microboiling, which uses tiny vapor bubbles to detect specific substances. The technique can measure changes in boiling behavior in just 5 microseconds, making it faster than typical lab techniques.
U.Va. researchers have identified T-type calcium channels as a key regulator of low-voltage-activated calcium channels, a crucial process in various cell types. This breakthrough could lead to the development of more specific and effective drugs for cardiovascular diseases.
Researchers sequenced 99.4% of gene-containing regions on chromosome 7 with high accuracy, revealing duplicated segments that may contribute to genetic diseases. The analysis also identified approximately 1,150 protein-coding genes, shedding light on the genetic basis of human disease.
Two studies clarify that ADHD and BPD are distinct disorders that can occur in adults, and identify bupropion as a possible treatment for both conditions. The medications used to treat ADHD may exacerbate manic symptoms, but addressing both disorders is crucial for improved functioning and well-being.
Researchers have discovered a single gene mutation in flies that provides resistance to multiple, chemically unrelated pesticides. This mutation has spread globally and has been linked to devastating consequences if not addressed through reassessment of current pest management methods.
The McGill University Health Centre has received significant funding for health research, with approximately thirty-five percent of grant applications awarded. Researchers such as Dr. Sam David and Dr. William Muller will investigate regeneration in the spinal cord and study the molecular basis of breast cancer development.
Rutgers University has been awarded millions by the NIH for its genetic research efforts, expanding its capabilities to study disease genetics globally. The new funding will support researchers in studying common pools of subjects to identify genes predisposing individuals to diseases.
The NIST-designed optical detector and ILX Lightwave Corp.-designed optical multimeter enable reliable optical fiber power measurements. Independent tests confirm the system's accuracy, with excellent agreement between NIST and its German and British counterparts.
Kansas State University has received $4.2 million from the National Science Foundation to support new science initiatives, including a project in ecological genomics that aims to understand how organisms respond to environmental changes caused by human activities. The project will use the tools of molecular genetics with ecology to inv...
A new study by Stanford Medicine researchers found that B cells play a significant role in acute kidney rejection, and targeting them may lead to more effective treatment. The study identified three distinct subgroups of acute rejection based on gene-expression profiles, which could help physicians tailor their treatment approaches.
A Cornell University study found city-grown air pollution, particularly ozone, hinders rural tree growth. Contrary to expectations, city trees outperformed their country counterparts in terms of biomass.
A new UK study led by Dr Stephen Farrall found that only around 15% of people were 'very' or 'fairly' fearful in the past year. The study aimed to improve the accuracy of statistics about fear of crime by asking new survey questions, suggesting that surveys may exaggerate fears.
Melbourne scientist Mike Hubbard overturns long-held assumption on calcium transport, revealing a new class of protein linked to breast cancer and fertility. His research suggests an alternative calcium transport system based on the Endoplasmic Reticulum, potentially leading to new drug developments.
A new study suggests that horizontal gene transfer occurs in flowering plants for thousands of ordinary genes, contradicting the traditional view that eukaryotes acquire genes only through vertical transmission. The research found anomalous genetic material in mitochondrial DNA chromosomes across different species.
The survival rate of ICU patients with acute respiratory failure (ARF) is influenced by the presence or absence of organ failure in other vital organs. Patients with ARF alone have a lower mortality rate compared to those with multiple organ failure. The study emphasizes the importance of treating all organs simultaneously for optimal ...
A recent study found that a sepsis drug, DAA, can significantly reduce hospital care and mortality rates among older patients. The study, which followed 386 patients over two years, showed that the drug improved survival rates and reduced the need for intensive care.
The human genome has been fully sequenced, revealing important genes and their biological significance. The sequence data is expected to aid in the understanding of genetic disorders such as cystic fibrosis and Williams-Beuren syndrome.
