Researchers hope a 'robo-nose' could give K-9 officers a break

Every day, thousands of trained K9 dogs sniff out narcotics, explosives and missing people across the United States. These dogs are invaluable for security, but they're also very expensive and they can get tired.

Mycoplasma genitalium's cell adhesion mechanism revealed

Researchers from the Molecular Biology Institute of Barcelona (IBMB-CSIC) and the Institute of Biotechnology and Biomedicine (IBB-UAB) have discovered the mechanism by which the bacterium Mycoplasma genitalium (Mgen) adheres ...

How microvilli form

The gut is lined by cells containing brush borders, which are composed of arrays of microvillar protrusions that help in nutrient absorption and provide a barrier against pathogens and toxins. Microbes such as E. coli can ...

Study uncovers new hurdle for developing immunotherapies

The body's immune system is a valiant weapon against disease, and harnessing its power through a technique called immunotherapy is at the forefront of current research to treat cancer and other diseases.

Newly discovered enzyme is 'firing pin' for plant immunity

Just like humans, plants have an immune system that helps them fight off infections. Plant immunity has some important differences: they don't make antibodies and can't fight off the same bug more quickly months or years ...

Computer simulation of receptors reveals a new ligand-binding site

Using a computer simulation of an important receptor, EPFL scientists have discovered a novel binding site for natural ligands and drugs. The new site might be present on other receptors and can be exploited in novel treatments ...

Artificial enzymes perform reactions on living cells

Nature has evolved thousands of enzymes to facilitate the many chemical reactions that take place inside organisms to sustain life. Now, researchers have designed artificial enzymes that sit on the surfaces of living cells ...
