An analysis of 35 popular phone-based sleep apps finds that while most help users set sleep-related goals and track and manage their sleep, few make use of other methods known to help the chronically sleep-deprived.
A new study evaluates conservation actions that could save the iconic Hawaiian Honeycreeper bird, also known as the “Iiwi,” providing land managers with guidance on how to save this important pollinator. The study demonstrates how the movement of Iiwi across the slopes of Hawaii’s volcanos in search of nectar from flowers can increase their risk of contracting disease and dying.
NASA's Aqua satellite observed how strong wind shear was literally pushing Tropical Cyclone Cook apart as it displaced the bulk of clouds to the southeast of the center.
NASA's Aqua satellite passed over Cook on April 11 at 0305 UTC (11:05 p.m. EST) and captured a visible and infrared image of the storm. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument took a visible image of the storm. The image showed that strong vertical wind shear had pushed the bulk of clouds and thunderstorms southeast of the center of circulation.
York biology Professor Sapna Sharma is interested in predicting the effects of environmental stressors – for example, climate change, invasive species, land use change and habitat alteration − on ecosystems, and improving the scientific approaches used to generate these predictions. Some of her latest research, funded by the Natural Sciences and Engineering Research Council (NSERC) and others, and published in Scientific Reports, suggests that environmental stressors are driving the long-term changes in ice seasonality.
Global warming will thaw about 20% more permafrost than previously thought, scientists have warned; potentially releasing significant amounts of greenhouse gases into the Earth’s atmosphere.
A new international research study, including climate change experts from the University of Leeds, University of Exeter and the Met Office, reveals that permafrost is more sensitive to the effects of global warming than previously thought.
Cholera cases in East Africa increase by roughly 50,000 during El Niño, the cyclical weather occurrence that profoundly changes global weather patterns, new Johns Hopkins Bloomberg School of Public Health research suggests.
The findings, researchers say, could help health ministries anticipate future cholera surges during El Niño years and save lives.
