The National Institute of Standards and Technology (NIST) has developed a new reference material for peptide analysis, which will improve the performance and reliability of experiments to measure peptides in biomolecular samples. The peptide standards project committee designed three synthetic peptides with varying lengths and net char...
A large-scale study found that coffee consumption is associated with lower uric acid levels, which appears to be due to components other than caffeine. The researchers suggest that decreased insulin levels and improved insulin sensitivity may contribute to the observed effect.
The technology uses magnetic fields to enable one-way communication from the surface to miners, but a new bi-directional PED will allow two-way communication, improving rescue operations. CSIRO's research has the potential to set an industry benchmark for safe mine operations.
A study found that men with a high rate of increase in prostate-specific antigen (PSA) levels before treatment have a higher risk of death from prostate cancer. Elevated PSA velocity was a stronger predictor of poor prognosis than other single indicators, such as biopsy Gleason scores or advanced disease categories.
Physicists at NIST recreate the historic double-slit experiment with atoms, demonstrating wave-particle duality and a novel technique for quantum computing. The researchers trap ultracold rubidium atoms in two overlapping lattices, creating a strobe-like effect that can be controlled.
Researchers have successfully engineered adult stem cells from human cord blood to produce insulin, a potential breakthrough in treating type 1 diabetes. The discovery uses complex signals produced by embryonic mouse pancreas to direct adult stem cells into islet-like cells, producing C-peptide and insulin.
Researchers at NIST developed a batch fabrication technique to create nanowire LEDs emitting ultraviolet light, which is crucial for data storage and biological sensing devices. The new method yields reliable, stable devices with excellent thermal stability and operational stability.
A study by Juan Alcacer and Wilbur Chung found that more advanced technology companies locate near universities to partner in research. These firms are attracted to regions rich with academic activity, rather than competitor-rich areas.
A Phase II clinical trial suggests that extracorporeal photopheresis (ECP) is effective in treating clinically active Crohn's disease, with a 50% response rate after 3 months of treatment. Patients who responded to ECP therapy experienced notable improvements in disease symptoms and signs within six weeks.
Dental patients can benefit from referring to tobacco-use telephone 'quitlines' for support in quitting smoking. A pilot study found that 25% of patients who used quitlines stopped using tobacco at six months, compared to 27.3% in the brief-counseling group.
A comprehensive study found that 85% of pediatric chemotherapy errors reached patients, with most common mistakes involving improper dosing and timing. The antimetabolite class of chemotherapeutic agents was most frequently associated with errors, highlighting the need for targeted medication administration safeguards.
A new study examines patterns of care for whiplash patients and finds that increasing the intensity of care is associated with slower recovery. The researchers suggest that early aggressive treatment may delay recovery by encouraging passive coping strategies, rather than improving outcomes.
Researchers have discovered a tool for rapid drug discovery by combining molecular fragments, allowing for more specific targeting of cancer cells. Additionally, two new peptides enable the labeling of proteins, enabling further study and modification.
A new gene therapy has been shown to completely eliminate osteoarthritic pain and significantly reduce long-term joint damage in genetically engineered mice. The therapy works by increasing opioid receptors on nerve cells, making them more responsive to naturally occurring painkillers.
A new research center at the University of Cincinnati is uniting biomedical competitors to fund medical technology development. The Minimally Invasive Medical Technologies Center (MIMTeC) will focus on translational research that enables U.S. companies to bring next-generation minimally invasive technologies to market.
A long-term study found that drinking 4 or more cups of coffee per day dramatically reduces the risk of gout in men. The study, which followed 45,869 men for 12 years, showed a 59% lower risk of gout among those who drank 6 or more cups of coffee daily.
Researchers at the University of Warwick have found fractal patterns in the solar wind that correspond to the Sun's 'storm season', indicating complex magnetic field activity. This discovery could improve our understanding of space weather and its impact on cosmic ray flux, as well as inform the development of fusion power.
A study of coronary artery surgery survivors found that patients with inflammatory rheumatic diseases like rheumatoid arthritis and lupus had more chronic inflammatory cell infiltration in their aortic walls. Smoking was also independently associated with increased inflammation, particularly in the inner adventitia.
A team led by Sally Johnson and Clive Upton assesses the BBC Voices project's 700 hours of sound recordings, showcasing diverse regional accents and vocabularies. The study explores how language relates to issues like gender, ethnicity, and media representation.
