Progress toward an antitumor vaccine

...une system, to battle cancer" In principle, by the same means used against infectious diseases: immunization. The production of a selective vaccine is not a trivial task, however. A team led by Horst Kunst at the University of Mainz has now found a way to bind a molecule that is typical for tumors to a ca...

CT scan reveals ancient long-necked gliding reptile

The specimens, which were found by Nick Fraser of the Virginia Museum of Natural History, came to Penn State to be scanned on the specialized CT scanner. "In some cases,...

Small, self-controlled planes combine plant pathology and engineering

...we can have two aircraft sampling pathogens at the same time but at different altitudes.” Schmale has used the small, self-controlled planes to collect samples of the fungal genus Fusarium tens to hundreds of meters above the surface of the earth. This genus contains some of the world’s most devastatin...

Each rake head had a rigid side made of wood (functional) and another side made of flimsy cloth (non-functional). The reward was placed in front of the rigid side of one rake, and in front of the flimsy...
