“The organic substances we have found occur in sufficiently large quantities to support bacterial growth. This turns the droplets into small dynamic universes, each of which supports certain forms of life,” says Tina Santl Temkiv, who conducted the new study as a PhD student together with her supervisor, senior researcher Ulrich Bay Gosewinkel, at Aarhus University’s Department of Environmental...

The 6.7)m channel water vapor (WV) images from GOES have been generally used as a tool for synoptic scale weather analysis since their availability in the early 1980's. However, WV images do have mesoscale applications as well. The availability of hourly WV images starting in late 1987 has permitted the monitoring of changes in mid and upper level moisture in the environment of convective storm...

H urricanes are strong tropical storms with maximum surface winds greater than 64 meters per second that originate from equatorial oceans. The eye of a hurricane is usually 30 to 50 kilometers wide, but the storm’s overall extent might exceed 600 km or more. The damaging winds, torrential rains, storm surges, and flooding caused by hurricanes make them one of the deadliest and costliest natural...

Serious challenges face American higher education and our nation’s continued economic competitiveness and security. Some of these challenges have been identified during the multiyear effort to reauthorize the Higher Education Act and in several recent reports, including A Test of Leadership: Charting the Future of U.S. Higher Education by the Secretary of Education's Commission on the Future of...

in order to recognize the wind erosion situation of a region, the survey of its windiness is not sufficient and the physical characteristics of earth are of importance too. in fact, the outbreak of dust storms in a region is due to the sensitivity of earth and domination of wind in that region. in this investigation we have tried to find a way for determining the regions in which a dust storm i...

This paper reviews the current state of observational, theoretical, and modeling knowledge of the midlatitude storm tracks of the Northern Hemisphere cool season. Observed storm track structures and variations form the first part of the review. The climatological storm track structure is described, and the seasonal, interannual, and interdecadal storm track variations are discussed. In particul...

Knowledge of coral recruitment patterns helps us understand how reefs react following major disturbances and provides us with an early warning system for predicting future reef health problems. We have reconstructed and interpreted historical and modern-day recruitment patterns, using a combination of growth modelling and in situ recruitment experiments, in order to understand how hurricanes, s...

G. S. Hall's (1904) view that adolescence is a period of heightened "storm and stress" is reconsidered in light of contemporary research. The author provides a brief history of the storm-and-stress view and examines 3 key aspects of this view: conflict with parents, mood disruptions, and risk behavior. In all 3 areas, evidence supports a modified storm-and-stress view that takes into account in...
