His research aims to reduce errors in assessments and provide more accurate representations of factors such as response and travel time.
A recent study conducted by Dr. Scott Sheridan at Kent State University found that almost 90% of residents aware of heat warnings took no action to avoid health issues. The study suggests that heat warning systems may need to be revised to better target vulnerable populations.
A Dartmouth researcher studied immigrant households to find that generational status, not income, has the most effect on immigrant dispersion. The study challenges current ideas about where immigrants live and suggests that states with multi-generational households may have easier socio-cultural and economic adjustments.
A massive Christmas week snowstorm broke records for snow intensity, size, and damages across the Ohio River valley. The storm dumped record snowfall, causing over $900 million in losses, including thousands of injuries and 17 deaths.
A study on the geography of education found that homeschoolers represent a significant segment of the education universe, estimated at 20% of privately-schooled population in the US. The number of homeschoolers has grown in states with low to moderate regulation, but data is still limited due to varying reporting requirements.
Forecasts project Illinois water use to grow faster than population, with increased demand for energy production. The Midwest region will need almost 17 billion gallons of water per day by 2025, mostly for electricity generation.
Researchers estimate that the most recent common ancestor of humanity lived around 3,000 years ago, sharing ancestors who domesticated horses and built ancient structures. The study used realistic computer models to simulate human history over the last 20,000 years.
A Dartmouth College study found that groups are less segregated at work than at home in greater Los Angeles, with interracial contact increasing during the workday. Notably, African Americans remain highly segregated both at work and home, while immigrants from Mexico and whites disperse more during the day.
Researchers found that racial segregation patterns diverge between home and work life, with blacks being the most segregated, while whites and Mexican immigrants work over wider areas. Workplace diversity is increasing due to immigration, potentially leading to reduced residential segregation in the future.
The Lewis and Clark expedition successfully traversed the new frontier due to a favorable climatic window that allowed for abundant food sources. If they had traveled during an intense drought, their journey might have been significantly impacted, potentially altering the course of U.S. expansion into the West.
Researchers at Johns Hopkins University have found that riverbank filtration can significantly decrease bacteria and viruses in drinking water, as well as reduce the presence of Giardia and Cryptosporidium. This technique involves passing river water through nearby sediment, which removes impurities and reduces treatment costs.
Scientists verify King Hezekiah's role in constructing the Siloam Tunnel by dating organic material and stalactites within the tunnel. The findings refute a recent claim suggesting a much later date for the tunnel.
The study found that household damages were not always proportional to levels of ground motion, with average damages being almost identical in high and medium ground motion zones. The majority of damage ($913 million) occurred in the medium ground motion zone, which is where nearly 60% of Puget Sound households are located.
A UC researcher used geological features and satellite imagery to identify a possible bin Laden stronghold in Afghanistan, which was later confirmed by US forces. He also warned the US government about the potential for Al Queda to return to the region.
A recent survey of homebuyers in Raleigh and Wake County found that the Internet has had a limited impact on housing search patterns, with half of respondents using it. However, those who used the Internet visited more houses in person than non-users, possibly due to younger age or higher energy levels.
Researcher Michele L. Aldrich found that Dickinson's poetry incorporated geological terms, indicating an influence from her education at Amherst Academy and Mount Holyoke College. This study aims to encourage students interested in geology to explore the subject through literary examples like Dickinson's poems.
ColorBrewer is a free web-based tool that enables users to select from various color schemes for their maps. The tool offers sequential, diverging, and qualitative schemes, allowing users to test and refine their choices. Additionally, ColorBrewer provides detailed color specifications for printing, projection, or web display.

The center's initiatives focus on urban livability and brownfield redevelopment, aiming to create jobs and improve tax bases while addressing environmental concerns.
A University of Cincinnati geologist has found that genera appearing after mass extinctions survived for longer periods than those that emerged at other times. The trend is attributed to their generalist characteristics, which allowed them to adapt to new geographic and environmental distributions.
The American Geophysical Union is hosting its Fall Meeting, featuring a range of scientific sessions and press conferences. Press registrants include over 60 journalists from major publications, covering topics such as climate change, natural hazards, and space exploration.
A Vanderbilt University-led excavation has uncovered a remarkably preserved 8th century Maya royal palace at Cancuén, Guatemala, featuring over 170 rooms and 11 courtyards. The site's unique design and fine limestone construction have allowed it to remain largely intact for over 1,000 years.
A Penn State biologist has identified 13 sunfish and sucker species as being at high risk of extinction, primarily due to their isolated distributions and limited geographical range sizes. The study found that larger body size is associated with a higher risk of extinction in sunfish, but not in suckers.
Scientists are using harmonic analysis on satellite images to study changes in vegetation during growing seasons and land use patterns. They can detect desertification, forest regeneration, and climate change by analyzing wave patterns and amplitude measurements.
Researchers studied Atlanta, Salt Lake City, and other cities using Landsat data, finding that adding trees and light-colored roofs can cool city temperatures. Computer models also simulated land use changes to predict stormwater runoff patterns and urban growth in abandoned strip mines.

A recent Penn State study found that new welfare reform legislation and abortion restrictions may have created a paradoxical outcome. The increase in single mothers, who are often on welfare, may be due to the decreased access to abortion services, leading more women to choose childbearing over termination.
The survey, a collaboration between National Geographic and distinguished sociologists, aims to map communities and change around the world. It will collect data from 18,000 participants and address how often people have moved, their role in communities, and the impact of geography on tastes.
A study by University of Idaho researchers reveals that trace elements in produce can determine its geographic origin through chemical analysis. The accuracy of this classification has been excellent with a model based on nearly l,000 potatoes, helping to combat mislabeling practices that harm consumers and growers.
Dr. Mather's research and teaching in climatology have made a lasting impact on the profession. He is recognized for his exemplary service to the Association of American Geographers (AAG) and his faculty colleagues.
Historically, colleges were established near trade centers, but today, more than half of four-year universities and two-year colleges are metropolitan institutions. This shift has significant implications for urban economies. The majority of institutions are now located near where people live, reflecting a change in the public's percep...
John R. Mather, a renowned University of Delaware geographer, has been awarded the Association of American Geographers' Lifetime Career Honor for his exemplary service to the profession and association over his entire career.
