New research enhances the current knowledge of how human immunodeficiency virus type-1 (HIV-1), which causes AIDS, controls the cell cycle of cells that it infects. The new findings may shed light on how the virus reactivates after entering a dorman…
Ensuring the sustainability of the products we use is a fundamental challenge for society, and is becoming ever more important for consumers and companies. A researcher from the University of Santiago de Compostela (USC) has come up with an ec…
A combination of rising costs, shrinking supplies, and concerns about global climate change are spurring the development of alternatives to the burning of fossil fuels to meet our transportation energy needs. Scientific studies have shown the mo…
Stanford, CA — Genghis Khan and his Mongol hordes had an impact on the global carbon cycle as big as today’s annual demand for gasoline. The Black Death, on the other hand, came and went too quickly for it to cause much of a blip in the global car…
SEATTLE — Try to schedule your screening mammogram during the first week of your menstrual cycle. It might make breast cancer screening more accurate for pre-menopausal women who choose to have regular mammograms. This recommendation comes from an …
Through an innovative use of cell phone records, researchers at UCLA, the University of Miami and Cal State, Fullerton, have found that women appear to avoid contact with their fathers during ovulation.
“Women call their dads less frequently on …
New University of Arizona research indicates that leaf vein patterns correlate with functions such as carbon intake and water use — knowledge that could help scientists better understand the complex carbon cycle that is at the heart of global …
Nine years after beginning its unprecedented look at the gateway between Earth’s environment and space, not to mention collecting more data on the upper atmosphere than any other satellite, NASA’s Thermosphere Ionosphere Mesosphere Energetics an…
In a bid to unlock long-standing mysteries of the sun, including the impacts on Earth of its 11-year cycle, an international team of scientists has successfully probed a distant star.
By monitoring the star’s sound waves, the team has observ…
Despite greatly increasing food production for humans, the growing use of nitrogen as a nutrient is affecting people’s health far beyond just the benefits of growing more crops, according to a new University of Colorado at Boulder-led study. Study leader Alan Townsend of CU-Boulder’s Institute for Arctic and Alpine Research said changes in the global nitrogen cycle, while beneficial in increasing crop growth, appear to pose a growing health risk. Roughly half of the inorganic nitrogen ever used on the planet has occurred in the past 15 years.
For the first time, scientists have incorporated multiple human and natural factors into a climate projection model. They predict that increased carbon dioxide in the atmosphere, due to changes in the carbon cycle, combined with a decrease in human-produced sulphates, may cause accelerated global warming during the 21st century, as compared with simulations without these feedback effects.
