New research from University at Buffalo biologists found that female butterflies are attracted to the sparkle created by ultraviolet reflectivity of pupils in male butterfly wings, not the size of the eyespots. Females prefer a set of narrowly defined features, such as eyespot pupils measuring approximately half a millimeter.
Researchers found that people constructing job criteria favor the strengths of dominant groups. However, committing to hiring criteria beforehand eliminates gender discrimination in hiring decisions.
The global survey found that 26% of respondents never disclose their bipolar disorder due to social stigma, while 71% believe the public does not understand their illness. The survey also revealed that successful treatment would lead to significant quality of life changes.
Researchers have identified 10,567 active promoters in the human genome using a set of DNA microarrays. This breakthrough may help investigate genetic causes of diseases and inform personalized therapies.
A study by University of Michigan researchers found that welfare reform led to increased rates of hypertension, obesity, and poor self-reported health among single mothers. The study's findings suggest that the impact of welfare reform on women's health was not fully considered in policy decisions.
A study by Michael Kitson of the Judge Institute of Management found that biotechnology firms believed economic changes had a negligible impact, but relied on large cash reserves for insulation. In contrast, aerospace firms developed portfolios of activities driven by different business cycles to reduce vulnerability.
Researchers found that Viagra can stimulate water permeability in kidney cells by increasing cyclic-GMP levels, potentially alleviating symptoms of nephrogenic diabetes insipidus. Long-term studies are needed to confirm the effectiveness and safety of this approach.
Researchers developed a tool that combines atomic force microscopy (AFM) with scanning electrochemical microscopy (SECM) to monitor both topography and biochemical activity simultaneously. The technology promises to be valuable for various biomedical and biotechnological applications, including studying cystic fibrosis.
A recent NCAR study found that Alaskan and Canadian wildfires emitted 30 teragrams of carbon monoxide, causing a 25% increase in ozone levels in parts of the northern continental US and a 10% increase in Europe.
A new promoter map has been created to understand how genes are controlled in fibroblasts, providing a framework for analysis of genetic control in other human cell types. The researchers discovered multiple promoters controlling single genes in parallel and found new DNA sequences not previously recognized as genes.
Researchers have discovered that nonlinguistic monkeys have an area comparable to Broca's area, which is responsible for controlling oral and facial actions. This finding suggests that Broca's area may have evolved to control certain aspects of the speech act in humans.
A multidisciplinary team at USC Viterbi School created a two-way voice translation system that turns doctor's English questions into Persian and vice versa. The Transonics Spoken Dialog Translator uses a combination of human observation, computer code, and machine learning to achieve fluent communication.
Researchers at Queen's University have discovered a 13-million-year cycle in the mountain-building process, which is significantly shorter than previously believed. This finding has implications for our understanding of geological processes that shape the Earth, including the formation of volcanoes and deep-seated continental earthquakes.
A new study shows that ACTOS significantly improved components of diabetic dyslipidemia compared to Avandia. The results indicate that treatment with ACTOS lowered triglycerides and increased HDL-C, while improving LDL-C particle concentration and size. This is important for reducing cardiovascular risk in patients with type 2 diabetes.
Researchers found that warmer air could increase Antarctic sea ice volume by suppressing ice below sea level and refreezing as thicker ice. This counterintuitive phenomenon is driven by thermohaline circulation, impacting global climate patterns.
A computerized water monitoring system is deployed on the historic schooner The Pioneer, measuring water temperature, salinity, and dissolved oxygen in New York Harbor. Students can access data from home to learn about forecasting and environmental monitoring.
An international team has launched the first detailed physical map of Drosophila buzzatii chromosomes, a species widely used in studies of genome evolution and ecological adaptation. The map was constructed using genomic library and physical mapping techniques, providing insights into the species' evolutionary history.
Researchers found that cobblestone walking improved balance, mobility, and reduced blood pressure in older adults. The activity, rooted in traditional Chinese medicine, has been shown to be therapeutic and can be done at home with manufactured mats.
The BioCassava Plus project aims to develop cassava plants with increased levels of zinc, iron, protein and vitamins A and E, while reducing cyanide content and improving shelf life. The five-year grant will be used to increase the root's nutritional value and resistance to devastating plant viruses.
Researchers have identified a molecular mechanism controlling lung dryness and fluid entry, potentially leading to better prognosis for those with acute respiratory distress syndrome. The discovery focuses on the SIP3 receptor, which, when activated, causes pulmonary edema, offering new avenues for treatment.
A study found that maximum avoidance inbreeding strategies can help reduce population crashes and extinction risk when released into the wild. This approach is more effective than limited inbreeding for certain species.
Researchers found that newborn dolphins and orcas remain active 24 hours a day in the first month, unlike all other mammals. This allows them to reduce danger from predators, maintain body temperature, and facilitate rapid growth.
Researchers at University of Colorado Boulder developed a new method to visualize forces beneath the Himalaya, allowing for a deeper understanding of earthquakes and mountain formation. The study uses seismic sensors and creates high-resolution images of the crust and upper mantle.
A new survey suggests that Seroquel provides significant quality of life improvements for bipolar patients, with 79% believing a successful treatment would lead to increased functionality and improved lifestyle. The medication has been shown to effectively manage symptoms of depression and anxiety in rapid-cycling patients.
Two scientists outline China's environmental impact on the world, including pollution, resource consumption, and human health dangers. They recommend education, environmental law enforcement, market tools, and lifestyle changes to address these issues.
Nanofluidic transistors, the basis of future chemical processors, have been successfully created by researchers. These devices can control fluid flow without moving parts, enabling applications such as cancer diagnosis and biomolecular sensing.
Research by Johns Hopkins physicists reveals that atomic-scale surfaces exhibit drastically different friction and adhesion forces due to their unique structures. The findings have significant implications for the development of nanotechnology, which could lead to improved device performance and functionality.
Astronomer Nicolas Dauphas has refined the accuracy of the cosmic clock by comparing the decay of uranium-238 and thorium-232, estimating the age of the Milky Way at approximately 14.5 billion years, plus or minus 2 billion years.
Researchers identify three reasons to be cautious about an autism epidemic, including a flawed California study and the lack of reporting category for autism in public schools. They propose that the increase in diagnoses may be due to broadened diagnostic criteria and increased public awareness.
