Methane-based greenhouse and anti-greenhouse events contributed to the Archean climate's stability. The presence of methanogenic bacteria played a crucial role in these processes.
The KamLAND experiment has confirmed the existence of neutrino oscillation and mass, supporting a long-held case. By studying anti-neutrinos from nuclear reactors, researchers found evidence of the same neutrino deficit as solar neutrino experiments, suggesting that neutrino masses are nonzero.
A study of Puerto Rican men found that small amounts of physical activity significantly protected against mortality, while moderate or intense exercise provided little additional benefit. Physical inactivity was a stronger predictor of death than being overweight or obese.
Researchers at NYU's Courant Institute found that flexible structures exhibit a unique drag reduction phenomenon, where the drag force decreases with the velocity of the flow. The team discovered that this occurs due to the shape of the fiber's 'nose' and its self-similarity under different velocities.
Researchers have solved the three-dimensional structure of a low-density lipoprotein (LDL) receptor's extracellular domain, which may help develop treatments for familial hypercholesterolemia. The LDL receptor plays a crucial role in clearing LDL from the blood and maintaining healthy cholesterol levels.
Phytoplankton, especially diatoms with silicon, play a crucial role in removing carbon dioxide from the atmosphere. However, warmer ocean temperatures hinder this process, creating a global warming Catch-22.
A URI biologist will monitor salt marshes in national parks for long-term ecosystem changes, enabling resource managers to anticipate detrimental changes and design management strategies. The study sites were selected based on aerial photography, field visits, and interviews with park staff.
Research reveals that women caregivers face significant pension disadvantages, with fewer years of contributions compared to men. The study advocates for policy changes, including extended parental leave and improved pensions, to address these disparities.
