A large international study found that passive smoking significantly increases the risk of respiratory symptoms, including nocturnal chest tightness and breathlessness. The prevalence of passive smoking in workplaces varied widely across countries, with some areas experiencing as much as 53.8% exposure.
Researchers found that increased concentrations of asymmetrical dimethylarginine (ADMA) are a strong predictor of death and cardiovascular disease in haemodialysis patients. Middle-aged men with normal kidney function also showed a higher risk of acute coronary events with high ADMA levels.
Scientists discover rare squid with thin tentacles, stretching up to ten times its body length. The finding suggests the creature is widespread and highlights scientists' depth of ignorance about deep oceans.
Researchers at the University of Washington have made significant progress in understanding how hydrogen atoms are transferred between molecules, a key step in creating new compounds. This breakthrough could lead to more efficient manufacturing methods, cleaner product development, and improved chemical reactions.
A study of 73 postmenopausal women found no significant changes in serum estrogen, cortisol, or follicle stimulating hormone levels after consuming soy protein for up to 6 months. Circulating thyroid hormone levels were modestly increased in those taking the highest dose of soy isoflavones.
The Kavli gift will enhance program flexibility and accommodate more scientists due to the institute's growing popularity. UCSB Chancellor Henry Yang praises the gift, calling it a 'lasting impact' on the scientific community.
The largest clinical trial ever of Parkinson's disease will be conducted by Professor Karl Kieburtz, with over 3,000 patients participating from 42 sites across North America. The five-year study aims to test the effectiveness of various substances in slowing disease progression.
Researchers found a significant link between sarcoidosis and family history, with affected individuals more likely to have siblings or parents with the disease. Air pollution during adolescence also affects lung function growth and performance, while improved HIV treatment reduces the risk of pulmonary complications.
Researchers have successfully created a novel chemical sensor based on an experimental physics phenomenon, allowing for the direct detection of molecules. This innovation has significant implications for various industrial applications, including manufacturing processes and environmental monitoring.
Researchers have identified a critical protein, SET7, that regulates gene expression by modifying histone H3. This discovery may lead to new treatments for diseases and provide insights into using stem cells to generate organs. The study reveals that SET7 makes chromatin structure more open, allowing other proteins to access genes.
Researchers created molecular-scale computing circuits that can carry out basic computing operations, paving the way for tiny but powerful machines. These circuits have the potential to translate conversations on the fly or diagnose illnesses quickly, and could provide computing power for decades to come.
A recent study published in The Lancet found that mentally ill patients are at a significantly higher risk of dying from homicide compared to the general population. The study analyzed data from over 72,000 individuals and revealed that those with mental illness were six times more likely to die by homicide.
A recent yellow fever outbreak in Guinea highlights insufficient international stocks of the 17D yellow fever vaccine, which can protect for at least 10 years. WHO recommends an emergency stockpile of 1 million doses to provide a rapid response to large outbreaks.
Researchers at Virginia Tech are exploring the development of new sensor approaches using nanotechnology, aiming to detect DNA and other biological compounds. They also aim to improve computational capacity by understanding electronic transport properties in molecular wires.
Harvard Medical School researchers have identified a key pathway controlling circadian rhythms in hamsters, revealing the signals sent by the body's internal clock and its connection to light exposure. The discovery opens new avenues for research into sleep disorders and could lead to improved treatments.
A protective protein called a chaperone suppresses the toxicity of alpha-synuclein, a protein associated with Parkinson's disease. The study found that augmenting levels of Hsp70 corrected the deficit and overcame the toxic effect of loss of chaperone function.
Researchers at Stanford Medicine developed a system to study genetics and evolution in natural populations using the three-spine stickleback fish. They found parallels between laboratory genetics and evolutionary changes in the fish, suggesting that evolution can occur through large-effect gene changes.
A recent study revealed that screening high-risk patients for diabetes may not be cost-effective, with a low yield and high cost. Additionally, a quality intervention to improve depression care was ineffective in real-world settings, highlighting the need for system changes to close care gaps.
A study published in the American Journal of Clinical Nutrition found that diets high in red meat, such as high meat or high milk diets, are associated with a higher risk of stomach and esophageal cancers. Diets rich in fruits, vegetables, and whole grains may help reduce this risk.
A study published in the European Journal of Clinical Investigation found an association between nitrate levels in groundwater and the incidence of SIDS. The researchers analyzed over 600 cases and discovered that deaths occurred more frequently during periods of high nitrate concentrations, particularly in areas with rapidly increasin...
A $46,000 grant will aid in identifying and addressing environmental issues facing ten National Park units. Mary-Jane James-Pirri will conduct field assessments and compile literature to create a comprehensive document on wetland health and management.
A team of Penn researchers found that molecular chaperones can block the progression of neurodegenerative diseases like Parkinson's by preventing neuronal decay in Drosophila melanogaster. The study suggests that activating these molecules may be an effective approach to treating several human neurodegenerative diseases.
Linoleic acid significantly induced mRNA transcripts of inflammatory genes, while oleic acid showed protective effects on arterial endothelial cells. This study highlights the importance of plasma fatty acid concentrations in vascular disease research.
Researchers at The Wistar Institute have identified a carefully orchestrated series of molecular modifications to p53 that must occur for it to perform its normal function. This discovery may suggest new ways to combat cancers where p53 is dysfunctional, and could also provide insights into the regulation of other DNA-binding proteins.
Researchers from Uppsala University developed new computer-based methods for Bayesian inference in evolutionary biology, enabling analysis of complex problems on ordinary desktop computers. The new methods can be applied to various fields, including species relationship reconstruction and molecular evolution studies.
