A new research brief from the US2010 Project shows that the average black or Hispanic household earning over $75,000 lives in a poorer neighborhood than the average white resident earning under $40,000. The US2010 Project's data show in most metro areas there are similar neighborhood gaps in median and per capita income; percent of residents with a college education or professional occupation; home ownership; and housing vacancy...

In a paper published recently in the journal Science, researchers at Brown University and from the Republic of Georgia have learned how bats can home in on a target, virtually dismissing other objects in their midst. The trick lies in their neurons: Bats can separate a cavalcade of echoes returning from their sonar blasts by distinguishing changes in amplitude "” the intensity of the sound "” between different parts of each echo within 1.5 decibels, to decide whether the object is...

Nursing homes in the United States are shrinking and their residents are becoming proportionately more black, more Hispanic, more Asian, and less white, according to a new study by Brown University researchers. The nationwide trend, reflected in metropolitan areas from New York to Los Angeles, results from changing demographics and disparities in what people can afford. The study is published in the July edition of Health Affairs. In the last decade, minorities have poured into nursing homes...

Dentists may unknowingly be playing a major role in the abuse of opioids, a type of prescription analgesic used to treat acute pain, according to a cover article published in this month's edition of the Journal of the American Dental Association (JADA). For the paper, which is entitled "Prevention of prescription opioid abuse: The role of the dentist," the nine authors--all dentists--participated in a two-day workshop, co-hosted by the Tufts Health Care Institute Program on Opioid Risk...

New research from Brown University shows that fish and mammals chew differently. Fish use tongue muscles to thrust food backward, while mammals use tongue muscles to position food for grinding. The evolutionary divergence is believed to have occurred with amphibians, though further research is needed to identify which species and when. Results are published in Integrative and Comparative Biology. Evolution has made its marks "” large and small "” in innumerable patterns of life....

Hepatocellular carcinoma is the most common cancer to strike the liver. More than 500,000 people worldwide, concentrated in sub-Saharan Africa and Southeast Asia, are diagnosed with it yearly. Most of those afflicted die within six months. A big obstacle to treatment of liver cancer is the lack of early diagnosis. Current techniques, including ultrasound, CT and MRI scans, spot tumors only when they have grown to about 5 centimeters in diameter. By that time, the cancer is especially...

Creatures are not born hardwired to see. Instead, they depend on electrical activity in the retina to refine the complex circuits that process visual information. Two new studies from Brown University in different species using different techniques show how nascent animal brains use light to wire up or construct their central vision system. Any parent knows that newborns still have a lot of neurological work to do to attain fully acute vision. In a wide variety of nascent animals, genes...

Computer scientists at Brown University have created software to examine neural circuitry in the human brain. The 2-D neural maps combine visual clarity with a Web-based digital map interface, and users can view 2-D maps together with 3-D images. The program aims to better understand myelinated axons, which have been linked to pathologies such as autism. Results are published in IEEE Transactions on Visualization and Computer Graphics. Medical imaging systems allow neurologists to summon 3-D...

The end of the Norse colonies on Greenland have long been shrouded in mystery, and while archaeologists have been able to fill in some blanks, there is limited written evidence of the colony's demise in the 14th and early 15th century. But now, new research from Brown University suggests that Greenland's early Viking settlers lived in a region with a rapidly changing climate with temperatures plunging several degrees on average in a span of decades. Climate scientists have been able to...
