San Jose, Calif., May 10, 2016 -- A team of more than 80 mathematicians from 12 countries has begun charting the terrain of rich, new mathematical worlds, and sharing their discoveries on the Web. The mathematical universe is filled with both familiar and exotic items, many of which are being made available for the first time. The "L-functions and Modular Forms Database," abbreviated LMFDB, is an intricate catalog of mathematical objects and the connections between them. Making those relationships visible has been made possible largely by the coordinated efforts of a group of researchers developing new algorithms and performing calculations on an extensive network of computers.

COLUMBIA, Mo. - According to the Centers for Disease Control and Prevention, Native American adolescents have higher rates of cigarette smoking than other racial or ethnic groups. New research from the University of Missouri on the smoking habits of Native American adolescents finds that family warmth and support, as well as participation in school activities, can play a role in tobacco prevention.

Acoustic warning signals emitted by tiger moths to deter bats - a behavior previously proven only in the laboratory - actually occur in nature and are used as a defense mechanism, according to new research from Wake Forest University.

Field research of free-flying bats conducted in their natural habitats by biology graduate student Nick Dowdy and colleagues shows that tiger moths produce ultrasonic signals to warn bats they don't taste good. This behavior - called acoustic aposematism - was previously proven in the laboratory by biology professor Bill Conner and Jesse Barber, who earned his doctorate at Wake Forest in 2007.

Researchers have compiled the first global set of observations of the movement of the Earth's mantle, the 3000-kilometre-thick layer of hot silicate rocks between the crust and the core, and have found that it looks very different to predictions made by geologists over the past 30 years.

WASHINGTON -- Evidence is mounting that the current outbreak of yellow fever is becoming the latest global health emergency, say two Georgetown University professors who call on the World Health Organization to convene an emergency committee under the International Health Regulations. In addition, with frequent emerging epidemics, they call for the creation of a "standing emergency committee" to be prepared for future health emergencies.

Microbiologists at The University of Texas at Austin and their colleagues have cracked the genetic code of how bacteria broke down oil to help clean up the Deepwater Horizon oil spill, revealing that some bacteria have far greater potential for consuming oil than was previously known. The findings, published in the journal Nature Microbiology, have applications for responding to future oil spills and other ecological disasters, while shedding light on the ways in which tiny microbes played an outsized role in limiting damage from the 2010 spill caused by the explosion of a BP oil rig.
