A study by Dr. Elizabeth Goodman found a significant association between socioeconomic status and depressive symptoms, obesity, and poorer ratings of overall health among teenagers. The research examined data from over 15,000 surveys and found that lower socioeconomic status was linked to higher rates of these chronic illnesses.
A recent study found that nearly half of people with type 2 diabetes stop taking their oral anti-diabetic drugs (OADs), leading to a higher risk of complications such as blindness, amputation, and cardiovascular problems. The study revealed that individuals who discontinued treatment were almost three times more likely to die than thos...
Researchers at University College London have developed a novel approach to determine the melting temperature of iron at high pressures, allowing them to estimate the Earth's core temperature. This breakthrough has significant implications for understanding earthquakes, volcanoes, and the Earth's magnetic field.
The American Association of Pharmaceutical Scientists has premiered an online database of the abstracts to be presented at the upcoming annual meeting. The database includes all invited and contributed paper abstracts, with a unique personal itinerary feature allowing attendees to plan their meetings.
A new watershed model, GISWA, can help predict the effects of forest practices on watersheds and wildlife habitat. The model simulates hydrologic conditions at thousands of locations within a single watershed to provide a detailed representation of water movement.
Researchers found that transmyocardial laser revascularization (TMR) improves angina by at least 2 classes in 72% of patients, while also increasing myocardial perfusion by 20%. TMR safely and effectively improved heart function over a 12-month period, driving its use with difficult bypass and angioplasty procedures.
A common intestinal parasite has rewritten the understanding of hemoglobin's evolution and role in nature. The parasite reveals that hemoglobin evolved primarily to handle nitric oxide rather than oxygen.
A robotic caterpillar, Moccasin II, has been developed to navigate through gas, water, and sewerage pipes in buildings damaged by earthquakes or explosions. The robot can successfully navigate multiple 90-degree bends and is equipped with lights, a video camera, and microphones to detect survivors.
New research in Conservation Biology found that fragmented rainforests can lose biodiversity for a century. The study, led by Thomas Brooks, suggests that conserving the most-recently isolated fragments will save the greatest number of species from extinction.
Biologists at Cornell University and Max Planck Institute found that Daphnia crustaceans can evolve quickly to cope with polluted water. The study showed that these tiny crustaceans adapted to handle less nutritious food, becoming a natural control for toxic cyanobacteria in Lake Constance.
Researchers found that women with BRCA1 or BRCA2 mutations have a 40% risk of local recurrence and developing new tumors, making breast-conserving therapy less optimal. The study suggests that mastectomy may be a more suitable treatment option for these women to reduce the risk of recurrent disease.
Researchers propose hormonal function change led to unique larval stage innovation, allowing population explosion among insect groups. Insects with complete metamorphosis have diverse habitats and food sources due to the lack of competition between juveniles and adults.
Researchers will collect snow samples from Illimani and Sajama mountains to understand the impact of El Nino and La Nina on precipitation patterns. The team's goal is to analyze climate conditions over the past two years using sophisticated chemical analyses of snow samples.
The study found elevated levels of DDE and mercury in bald eagle eggs on Kiska Island, but not on other islands. Seabirds are thought to be the major source of contamination due to their diet rich in fish from contaminated water.
A study by Anthony Ricciardi and Joseph Rasmussen reveals freshwater species are dying out five times faster than terrestrial species. At this rate, many at-risk species will disappear within the next century, with non-native species and dams identified as major threats.
A new device called the chaos mirror is invented to improve infrared networking technology in crowded offices. It uses a box enclosing seven highly reflective surfaces to split narrow incoming beams into a widely spread array of reflected beams, vastly increasing the chances of beam finding its target.
A new device measures macular pigment to study its correlation with macular degeneration, the leading cause of blindness. The portable device uses LEDs and takes about 10 minutes to measure a patient's macular pigment levels.
Researchers found moose pregnancy rates fell from 90% in 1966 to 75% today, indicating limited food availability. The abundance of willows limits the number of moose, not wolves and grizzly bears, according to the study.
New research predicts that up to half of African primate species could go extinct within decades due to habitat loss. The study suggests an 'extinction debt' has been incurred as a result of widespread deforestation in Africa.
Researchers found that patients who previously received hormone therapy with tamoxifen, had no prior chemotherapy, and had limited metastases were more likely to live longer after high-dose chemotherapy with transplant. This study suggests that closely monitoring high-risk patients can improve treatment outcomes.
Ernie Croot, a graduate of Centre College, solved the problem, showing there will always be some way to find one of these special sets. The solution has connections with deep questions in theoretical computer science.
A Wake Forest University study found that soy high in isoflavones can dramatically lower LDL cholesterol levels by up to 10% and total cholesterol by up to 9%. The study also showed a dose-response relationship between isoflavone content and cholesterol-lowering effects.
