A study published in The Lancet found that UK armed forces personnel who took part in the 2003 Iraq War experienced slight rises in common symptoms, but not to the same extent as those who fought in the 1991 Gulf War. Fatigue was not increased after the 2003 Iraq War.
A new study offers a simpler approach to diagnosing urinary incontinence in women by asking patients three simple questions. Meanwhile, an update to the US hepatitis C profile reveals that infected individuals are entering their 40s and 50s, increasing the risk of disease consequences such as cirrhosis and liver cancer.
Researchers have created a massive 3-D map of the universe, mapping the distribution of galaxies and providing new insights into dark energy. The map uses luminous red galaxies as 'lighthouses' to measure distances, covering vast scales of up to a billion light-years across.
The Australian Diabetes, Obesity and Lifestyle Study found that approximately 100,000 adults develop diabetes annually, with nearly 600 people progressing to obesity every day. The study also revealed a significant increase in hypertension and chronic kidney disease among the Australian population.
A team of researchers at Penn State has discovered a mathematical description of a contracting universe that existed before the Big Bang, with space-time geometry and gravity exhibiting unique properties. The findings rely on loop quantum gravity theory, which proposes a discrete 'atomic' structure to space-time.
Researchers found that females who obtained the morning-after pill from pharmacies waited significantly less time than those from family planning clinics, with a median wait of 16 hours versus 41 hours. This timely access led to a 10% reduction in unwanted pregnancies.
The center will support development of new therapies for heart, cancer, and neurological disorders through early patient clinical trials. Non-embryonic stem cell research has been exceptionally strong in Ohio, bringing together academic investigators and industry partners to accelerate moving cutting-edge research into the clinic.
A study found that exposure to The Daily Show led participants to rate candidates more negatively and view the political system as more cynical. Researchers conclude that this may deter young Americans from voting. The study's implications for political participation should be explored further.
Physicists verify Chandra Varma's microscopic theory of high-temperature superconductivity using neutron scattering experiments. The results suggest ways to fabricate room temperature superconductors and shed light on a major mystery in physics.
A collaborative study successfully applied neutrons to locate hydrogen atoms in proteins, revealing how water molecules interact with proteins and influencing their function. The research demonstrates potential for understanding hydrogen-atom transfer processes in large biological systems.
A natural experiment found that open-access articles in PNAS gained a significant citation advantage over non-OA articles, being twice as likely to be cited within 4-10 months and almost three times more likely between 10-16 months after publication. The study suggests that open access accelerates the dissemination of scientific research.
Scientists mimic worm brains and fish jaws to develop brain-inspired sensors and gain insight into human memory formation. Researchers also explore biological inspiration for legged robots, prosthetics, and tissue engineering.
A year-long treatment improved neurologic outcomes for infants and children with toxoplasmosis. Seventy-two percent of those with moderate or severe disease had normal long-term cognitive outcomes. Comprehensive screening for pregnant women and newborns is recommended to prevent this acute parasitic infection.
A cell biology study has identified distinct signaling pathways between neurokinin-1 receptors and substance P, which could be used to block HIV entry into macrophages. The findings also highlight the potential of a drug called aprepitant as an HIV treatment.
Researchers argue for alternative approach to vaccine distribution, considering individual's degree of life investment and life expectancy. Healthy people from early adolescence to middle age are prioritized for vaccination, aiming to maximize years of life.
Researchers have discovered a new compound that specifically targets FKBP38 receptor, reducing programmed cell death in neuronal cells. The compound protects neurons and promotes neural stem cell proliferation, offering potential therapeutic application for stroke and other neurodegenerative diseases.
A new study from the University of Wisconsin-Madison found that a negative energy balance, induced by exercise and lower body weight, inhibits the growth of polyps in mice. The researchers also discovered that exercising mice had fewer polyps and less body fat compared to non-exercising mice.
A study of UK armed forces personnel deployed to the 2003 Iraq War found no specific health effects on regular service members. However, reserve personnel reported higher rates of physical and mental illness due to deployment-related stresses.
A new study suggests that body mass index (BMI) standards for younger adults may not be appropriate for people in their 80s and 90s. The analysis found that those who were overweight had the lowest mortality rates, while being underweight led to higher mortality rates.
Scientists discover a new compound, PI-103, that effectively inhibits the spread of brain cancer by targeting two separate steps in the signaling pathway. This dual blockade proves to be safe and effective in slowing down cancer cell proliferation in mice with human glioma cells.
A recent study found that coral reefs in the Seychelles have suffered severe damage from global warming, leading to a 90% decline in coral cover and a significant loss of biodiversity. The damaged reefs are unable to reseed and recover, resulting in profound impacts on other organisms in the ecosystem.
The Rwenzori Mountains' glaciers are receding at a rate of tens of meters per year, halving their area between 1987 and 2003. The researchers expect the remaining ice to disappear within twenty years due to increased air temperature without significant changes in precipitation.
Researchers found that caterpillars respond to variations in plant volatile production to reduce encounters with parasitic wasps. The study demonstrates that plant volatiles, rather than light, control the daily behavior of caterpillars.
Researchers have found metal fullerene clusters, also known as hollow golden cages, composed of gold atoms. These structures are stable at room temperature and can cage smaller atoms, opening up new possibilities for influencing physical and chemical properties.
Researchers have discovered that a specific neural stem cell gene, SOX2, is crucial for the normal development of the eye. The study found that disruption of this gene leads to abnormalities in eye formation and microphtalmia, a condition affecting 10% of human cases. The severity of the condition depends on the degree of SOX2 disruption.
Researchers have identified the specific step in the neurogenesis pathway that Prozac (fluoxetine) stimulates, increasing the number of neurons in the brain. The study's findings lay the foundation for future cell replacement therapies for neurodegenerative diseases.
Researchers discovered a novel compound, PI-103, that cooperatively inhibits both p110α subunit of PI3 kinase and downstream molecule mTOR. This dual inhibition shows high effectiveness against human gliomas in mice without toxicity.
