Ants show us how to make super-highways

...ed with different sizes of hole into the army ants trails to see how well different sizes of ant matched different sizes of pot hole. Indeed, they fit beautifully", explained Franks. Overall, this behaviour results in an increase in the average speed of prey-laden traffic. Moreover, calculations suggest ...

Uganda's mountain gorillas increase in number

... addition to census methodologies such as counting trails and nests (gorillas construct a nest each night), researchers used genetic analyses as well, specifically because many of the groups were clustered in the same area of the park, which presented survey teams with the risk of double-counting the same i...

Syphard collaborated with the U.S. Forest Service's Northern Research Station in Evanston, Ill., to create the computer models. "We found that, in terms of fir...

Plant-derived molecules, genetic manipulation point to future chemoprevention methods

...hat the triterpenoid CDDO-MA, currently undergoing trails for leukemia and solid tumors (sponsored by Reata Pharmaceuticals), significantly reduced the number and sizes of tumors in mice. In addition, a chemically related drug developed by Ligand Pharmaceuticals called LG100268 was effective at preventing t...

Gene-regulating enzyme is also a target for anti-depressive drugs

...rs of that second enzyme are currently in clinical trails as cancer therapies. "Might particular monoamine oxidase inhibitors, currently used primarily to treat depression, have anti-cancer activity too?" Shiekhattar says. "Our findings indicate this could be the case, and we are currently screening these d...

In looking for this structure, the researchers used a new electron microscopic method which was developed in the Department of Molecular Structural Biology at the Max Planck Institute of Biochemistry, and which ...

Underneath it all

Beetles, which could be a mighty hard catch for some spiders, avoid the presence of fresh silk, according to Ann Rypstra (Miami University, Ohio, US) and Christopher Buddle (McGill University, Quebec, Canada). In their study, Rypstr...
