Researchers track ammonium source in open ocean

: At different times of the year, prevailing winds blow into Bermuda from open ocean to the south or from the continental United States — an ideal laboratory for studying pollution generated by human activity. One surprise: Rain samples show that humans are adding far less ammonium to the oceans than researchers had thought.

Can the wave function of an electron be divided and trapped?

Electrons are elementary particles — indivisible, unbreakable. But new research suggests the electron's quantum state — the electron wave function — can be separated into many parts. That has some strange implications for the theory of quantum mechanics.

All aboard the Urban Studies bus tours

Faculty members from the Urban Studies Program will lead bus tours of Providence, focusing on different themes: schools, street art, waterfront, urban agriculture and others. The tours, free and open to the public, begin and end on the Brown campus.

Taubman Center’s new poll on AG, governor races

Brown University’s A. Alfred Taubman Center for Public Policy and American Institutions has conducted a new public opinion survey of 500 registered Rhode Island voters on the current gubernatorial and attorney general races.

Infection outbreaks, unique diseases rising since 1980

Ebola has a lot of company. In a novel database now made publicly available, Brown University researchers found that since 1980 the world has seen an increasing number of infectious disease outbreaks from an increasing number of sources. The good news, however, is that they are affecting a shrinking proportion of the world population.

Naloxone toolkit debuts with input from Rich, Green

Jody Rich and Traci Green, both medical faculty members at Brown and Lifespan experts in overdose, contributed to a new U.S. Department of Justice toolkit aimed at helping law enforcement agencies use the overdose death-preventing drug naloxone.

If CD8 T cells take on one virus, they’ll fight others too

CD8 T cells are known for becoming attuned to fight a specific pathogen (“adaptive immunity”), but a new study shows that in that process they also become first-responders that can fend off a variety of other invaders (“innate immunity”). The findings suggest that innate immunity changes with the body’s experience and that the T cells are more versatile than thought.

New evidence for exotic, predicted superconducting state

A research team led by a Brown University physicist has produced new evidence for an exotic superconducting state, first predicted a half-century ago, that can arise when a superconductor is exposed to a strong magnetic field.

The Bell Gallery presents SHE

Brown–Vernadsky collaboration

Head honored for international space science collaboration

The planetary science collaboration between Brown University and Russia’s V.I. Vernadsky Institute has grown over more than four decades, surmounting Cold War hostilities and geographic distance to build an astonishing record of scientific discoveries about the solar system. Participants gathered recently in Moscow to celebrate those contributions and Brown University’s 250th anniversary celebration.
