Smoking ban dramatically reduces air pollution in Irish pubs

...trated an 83 percent reduction in tiny particulate matter in bar air. "These results confirm that the approach of a total ban on smoking in the workplace is successful in reducing the exposure of workers to particles," said Dr. Clancy. "We have previously shown that a reduction of particle levels in ambi...

Prehistoric mystery organism verified as giant fungus

... largest-known organism on land in its day. "No matter what argument you put forth, people say, well, that’s crazy. That doesn’t make any sense," said C. Kevin Boyce, an Assistant Professor in Geophysical Sciences at Chicago. "A 20-foot-tall fungus doesn’t make any sense. Neither does a 20-foot-tall alga...

Bacteria research offers hope for new vaccine against meningococci

Without treatment, mortality among those who contract the disease is 85-90 percent, with treatment some 10-15 percent. Patients also run a high risk of serious disability after recovery. Only humans are susceptible to i...

Biologists call for better choice of model organisms in 'evo-devo'

...oosing new models in this way leaves it entirely a matter of chance whether a new model will illuminate a particular evo-devo theme. "Instead, we urge workers to select new models specifically to illuminate hitherto neglected general themes within evo-devo.". In other cases, new model organisms are c...

Researchers to study why dead zone returned to Lake Erie

...bra mussels may shunt the oxygen-consuming organic matter from the near shore to the bottom waters. In the third scenario, global warming has caused the layer of bottom water to become thinner, with less oxygen. The dead zone materialized in Erie's central basin and can cover as much as three quarters of ...
