A new mathematical model explains changing patterns in epidemics by analyzing historical data on measles outbreaks. The research reveals that increases or decreases in birth rates or vaccination rates cause dramatic changes in epidemic patterns.
University of Colorado researchers found that the production of antibiotic actinomycin D was 75% higher in space than on Earth, with a 20-fold increase in fermentation efficiency. This breakthrough has implications for developing new anti-cancer therapies.
Researchers visualize radiation-induced breakage of specific chemical bonds in protein, revealing a highly specific phenomenon. The findings have direct implications for improving data collection using X-ray crystallography and developing pharmacological means to protect against radiation damage.
Researchers have made significant breakthroughs in functional MRI technology, enabling accurate mapping of cortical columns, the brain's microprocessors. This advancement will greatly improve our understanding of human perception and higher cognitive functions.
Researchers found that carbon dioxide from human activities primarily ends up in the subtropical ocean, rather than the cold Southern Ocean. This new understanding challenges previous models and highlights the complexity of global ocean carbon sequestration.
A study by Professor Robert L. Brown suggests that maintaining a larger labor force and increasing productivity can mitigate the impact of baby boomers' retirement on society. By keeping workers in the workforce longer and investing in education and capital, it is possible to produce enough goods and services for the economy.
A study by UCSF researcher Shelley Adler found that only a third of women with breast cancer disclose using alternative treatments to their medical doctors. The main reasons for remaining silent were attitudes toward physicians and the perception that disclosure was not relevant to the doctor-patient relationship. Women tend to discuss...
A University of California, San Francisco study found that screening mammography in elderly women aged 66-79 reduced their risk of developing metastatic breast cancer by 43% compared to those who were not screened. This is the first evidence that mammography is beneficial for these women.
A study using satellite instruments reveals that the atmosphere has gotten warmer and wetter over the past decade. Water vapor levels in the atmosphere have increased by 2%, indicating a significant change in climate dynamics.
A Colorado State University professor believes that groundhogs emerge from hibernation based on their linoleic and linolenic acid levels. He suggests that these fatty acids affect the animal's activity levels during hibernation, rather than traditional shadow tricks.
Carnegie Mellon's Big Signal allows users to explore Antarctica remotely through Nomad's sensors and cameras. The project aims to engage students in remote geology and provide them with access to scientific data.
A new model predicts that expanding potent HIV therapies will limit infections and AIDS deaths, even with increased risk behavior and drug resistance. The model shows that treating more HIV-infected men will reduce infection rates and deaths below what they would be without treatment.
A new study found that flu in children results in substantial use of outpatient medical resources, including 10 physician visits and over half resulting in antibiotic prescriptions. The study suggests that recommending an annual flu vaccine for all children could be a cost-effective national policy.
Researchers use oxygen isotope fingerprinting to uncover evidence of lost Asian emerald sources in antiquity, tracing gems from Pakistan, Afghanistan, and Colombia. The study reveals a significant role for the Spanish in introducing New World emeralds into Old World trade.
