A Stanford study estimates that fewer than half of people with osteoporosis have been diagnosed, highlighting the need for better screening and treatment. The study found that new prescription medications have improved diagnosis and treatment rates, but more work is needed to catch cases early.
Researchers monitored PAHs in smoke and soot after 9/11, finding high levels initially but diminishing rapidly. The study suggests little lifetime cancer risk for people living near Ground Zero, but possible effects on unborn babies.
Research reveals that mosquitoes like Aedes aegypti are less likely to develop high levels of insecticide resistance due to a silent genetic mutation. The study found that only one base mutation is needed for some mosquito species, like Anopheles gambiae, but two adjacent mutations are required in others, including Aedes aegypti.
Pigeons with homing experience were significantly attracted to highways and a railway track, especially during early and middle sections of their homeward journeys. The researchers found that the birds may use cognitive strategies to locate their loft by relying on topographical points and road features.
Researchers have identified a gene essential for the synthesis of a novel plant hormone that regulates shoot branching. The hormone is believed to be a carotenoid derivative, with a protein that can cleave carotenoids such as carrots' orange pigment.
Fetal stem cells have shown promise in treating stroke damage, outperforming adult cells and overcoming embryonic cell limitations. Researchers are now exploring the potential of these cells to aid recovery after a stroke.
Researchers studied beaked whale responses to sound frequencies and decibel levels, revealing overestimated deep water impacts and new insights into shallow water reverberations. The study aims to improve safety guidelines for seismic operations in U.S. waters.
A study found significant socioeconomic disparities in cervical cancer among American women, with higher poverty levels and lower education associated with increased incidence and mortality rates. Women from low-income census tracts were 20% more likely to be diagnosed with late-stage disease than those from high-poverty areas.
A Queen's biologist calls for immediate protection for two distinct rock ptarmigan populations in Newfoundland and Alaska, citing genetic differences and threats from human activities. The study's findings suggest that these populations should be considered separate species, deserving special preservation under the Species at Risk Act.
Immune cells that get trapped in atherosclerotic plaques attract more immune cells, setting up a cycle that leads to continued progression of the disease. Monocytes take up permanent residence in plaques due to altered differentiation factors.
A study found that physical symptoms, such as shortness of breath and weakness, predict cancer prognosis. Physical health-related quality of life (hrQoL) factors were stronger predictors of survival than psychosocial factors.
Osteoporosis patients in US saw a four-fold rise in doctor visits from 1994 to 2003, driven by new medication availability. This trend shows improved treatment options for osteoporosis, but highlights the need for prevention strategies such as calcium use and physical activity.
A new grant will investigate how electron-beam irradiation can sterilize spacecraft components, focusing on heat-sensitive materials. The goal is to develop a more effective and reliable sterilization technique for deep space missions.
A new study provides detailed insights into the genetic diversity of Group A Streptococcus (GAS) strains, revealing why some rapidly expand to cause epidemics. The research reveals previously unknown genetic distinctions in M3 strains of GAS.
A K-State researcher found a link between smoking, vitamin A deficiency and emphysema in rats. The study shows that benzopyrene, a common carcinogen in cigarettes, induces vitamin A deficiency, which can lead to increased emphysema scores.
A new study published in the Proceedings of the National Academy of Sciences found that leptin triggers production of áMSH, a powerful peptide signal that boosts metabolism. This discovery could lead to the development of obesity treatments that increase energy production and promote weight loss.
A study of 154 hospitalized stroke patients found that antihypertensive therapy was used more frequently than recommended by clinical guidelines. The majority of patients experienced relative hypotension, and one in 20 developed frank hypotension.
Researchers discover new method for growing tiny tubes, similar to those found in caves and at hydrothermal vents. The discovery uses a controlled laboratory setup to replicate the formation process, allowing scientists to study it on human time scales.
Researchers link warmer temperatures to earlier flowering times in plants, with a significant trend observed over the past century. The study suggests that existing collections of herbarium records can be used to measure regional effects of climate change on phenological events.
The three-year funding supports a joint effort to apply Multiple Dirichlet Series to analytic number theory, a central area of modern mathematics. This could lead to new insights into long-standing problems in number theory.
Research reveals that women are 25% more likely to experience migraines before menstruation and that severe attacks often occur during pre- and post-menstruation intervals. Medication frovatriptan shows promise in preventing menstrually-related migraines, with over half of patients experiencing no migraine attacks.
Researchers found a series of genes defining a two-segment periodicity in centipede embryos, resulting in single segments that later develop legs. This mechanism limits the number of leg-bearing segments to odd numbers, with additional non-leg bearing segments also formed.
A study by the Genetic Epidemiology of Lung Cancer Consortium (GELCC) found strong evidence for a lung cancer susceptibility gene co-inherited with a genetic marker on chromosome 6. The researchers identified a region of interest on chromosome 6q23-25, which contains multiple genes that may contribute to lung cancer risk.
A study found that 65% of physicians made treatment decisions inconsistent with their patients' advance directives. Despite the presence of these documents, physicians prioritized other factors in difficult clinical situations. The authors emphasize the need for improved conflict resolution in end-of-life decision making.
Rice University's 'Nanotechnology: Content and Context' course combines technical content with social context to prepare students for a future where nanotech is integral. The course, led by CBEN faculty, explores four theme areas: scale, life, risk, and environment.
A yearlong study found that negative self-image in adolescents fosters increasingly damaging behaviors, including social isolation, peer conflict, and victimization. The study suggests that early intervention is needed to improve peer interactions in schools.
The aloe vera-derived fluid improved survival rates in rats with hemorrhagic shock, even without resuscitation, suggesting its potential to increase survival in trauma patients. The researchers believe the fluid could be administered before evacuation to medical units, reducing the need for blood transfusions.
The new magnet features a uniform field of 21.1 Tesla in a volume 64 times larger than typical NMR systems, allowing for a wider range of scientific experiments. Scientists can now explore new avenues in chemical and biomedical science using this unique national resource.
Early visual experience is crucial for normal development of color constancy in humans and monkeys. The study shows that baby monkeys raised in monochromatic environments had severe deficits in color constancy, highlighting the importance of early exposure to a diverse range of colors.
A new neurostimulation system uses continuous electric field adjustments to provide real-time, dynamic paresthesia steering for improved pain relief. This innovative technology enables up to 71 combinations of stimulation settings, leading to enhanced therapeutic possibilities.
