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.
