Researchers discovered that Streptococcal bacteria use an enzyme called streptokinase to block the human blood clotting response and spread within the body. The study found that subtle variations in plasminogen genes may explain why some people are more susceptible to strep infections.
Researchers at Medical College of Georgia have discovered a new category of multi-potent cells called VENT cells, which play a critical role in development and contribute to the formation of various human tissues. The discovery challenges long-held notions about what type of cells form specific types of tissue.
A large-scale study validates the benefits of low-GI diets in rats, showing significant reductions in body fat, blood glucose and insulin levels. The study suggests that glycemic index is an independent factor contributing to major chronic diseases.
A new modeling approach predicts how long pollutants will stay in soil by using a method developed by medicinal chemists to understand chemical interactions with natural organic matter. This tool could help environmental regulators and cleanup consultants make informed decisions about hazardous contaminant persistence and migration.
Researchers discovered that streptokinase, an enzyme produced by Streptococcus, enables its infection in humans while showing minimal activity against other mammals. The study creates a transgenic mouse model for studying human-specific microbes.
A team of scientists at PNNL has observed real-time interactions between single proteins, supporting the 'fly-fishing mechanism' theory. The technique used, single-molecule photon stamping spectroscopy, allows for dynamic measurements of protein dynamics.
Researchers fitted six-week-old tiger cubs with radio collars to study mortality rates and potential improvements. The third generation of radio-collared tigers for the project will enable scientists to track the cubs until they die or their collars fall off.
A Nordic study found statins decrease mortality rate and incidence of cancer over 10-year follow-up. Statin therapy with simvastatin reduced cardiovascular and coronary mortality, with a 17% reduction in cardiovascular mortality.
A Japanese study found that neuraminidase inhibitor oseltamivir-resistant viruses emerged more frequently in children treated for influenza, posing a potential risk of transmission. The research also highlights the need for further investigation into the mechanisms of resistance to prevent and treat future pandemics.
The Clemson University program aims to help undergraduates develop team-building skills, adapt to the industry pace, and understand marketability of their research. With $85,000 grant from NSF, students will collaborate with industry leaders and faculty to gain insights into the school-to-work transition.
Emselex(R) has been proven to improve overactive bladder (OAB) symptoms without causing significant adverse events. The treatment has shown efficacy in reducing urinary urgency and urge incontinence, making it a promising new option for patients.
Researchers at OHSU-VAMC found that estrogen increases regulatory cells and FoxP3 protein, key for fighting autoimmune diseases like MS. The study provides a new mechanism for understanding how pregnancy reduces MS symptoms.
Paediatric research is crucial for disease prevention and treatment, yet data are lacking due to a lack of legislation requiring companies to conduct trials on children. The UK Government's new initiative aims to invest £100 million in research networks but falls short of centre stage for acquiring research-based evidence.
Researchers at McGill University have made a groundbreaking discovery that patients can be infected with more than one type of HIV, which poses significant challenges for treatment and management. The study's findings, published in the August issue of AIDS, suggest that existing drug cocktails may need to be tailored accordingly.
The study identifies special bonding states at silicon / silicon dioxide interfaces, which can be observed due to the structure of a (111)-terminated silicon crystal. Nonlinear-optical spectroscopy provides high interfacial sensitivity, allowing for detailed analysis of oxidation processes.
The Donald W. Reynolds Foundation has awarded UT Southwestern a $12 million grant to continue the Dallas Heart Study, which aims to develop new biotechnology and treatments for heart disease. The study has already made significant discoveries, including identifying key chemical signals that change stem cells into heart cells.
A study of Japanese children with influenza treated with oseltamivir found nearly 20% produced mutant drug-resistant viruses within four days. The study highlights the risk of rapid emergence of resistant flu viruses, threatening a line of defense against deadly diseases.
A new study by Dr Bridgette Sullivan-Taylor of the University of Warwick explores the strategic management implications of global terrorism on international service organizations. The research highlights the impact of terrorism on organizational learning, planning, and decision-making for both business and leisure travelers.
The University of Pittsburgh has received a $10 million federal grant to enhance the quality of life for head and neck cancer patients. Researchers will investigate genetic changes, intracellular signaling proteins, and new treatment strategies to reduce morbidity and mortality from head and neck cancer.
Researchers at Los Alamos National Laboratory have developed a process to modify silica aerogels with silicon and transition metal compounds using chemical vapor techniques. This enhancement increases the aerogel's strength by four-fold while retaining its valuable porosity and density characteristics.
The fellowship program, supported by the Burroughs Wellcome Fund, provides a unique opportunity for science writers to gain in-depth knowledge and network with top scientists. The program includes transportation, accommodation, and meal costs, as well as a personal mentor.
Researchers have explained puzzling behavior in a high-temperature superconductor by discovering an electronic crystal, where electrons arrange themselves into a neat pattern. This phenomenon occurs in a phase called pseudogap and was observed using a highly sensitive scanning tunneling microscope.
A 56-year-old man with a cancer-induced jawbone removal underwent a new bone grafting procedure, resulting in successful bone remodelling and mineralisation. He regained the ability to chew and enjoyed his first solid meal in 9 years after transplantation.
A new theory explains how drizzle forms within typical cloud lifetimes, providing insights into local weather and global climate. The research suggests that a statistical barrier speeds up drizzle formation, allowing fewer large drops to dominate the process.
Researchers at Columbia University Irving Medical Center discovered that mutant alpha-synuclein protein causes blockage in dopamine neurons, leading to their death and eventually Parkinson's disease. This finding may aid in the development of new treatments to slow or stop disease progression.
A new study reveals that recreational fishing accounts for nearly a quarter of the total take of overfished populations, including many economically valuable species. Recreational catches outstrip commercial landings in specific depleted populations, such as red snapper and gag in the Gulf of Mexico.
