Understanding bacteria's slimy fortresses
For the first time, scientists have revealed the mechanics of how bacteria build up slimy masses, called biofilms, cell by cell. When encased in biofilms in the human body, bacteria are a thousand times less susceptible to antibiotics, making certain infections, such as pneumonia, difficult to treat and potentially lethal. In a new study, engineers and biologists tracked a single bacterial cell as it grew into a mature biofilm of 10,000 cells with an ordered architecture. The findings should help scientists learn more about bacterial behavior and open up new ways of attacking biofilms with drugs.

Paving the road to drug discovery
There are many disadvantages to using human cells in the initial stages of creating a new therapy. Scientists often have to test a large number of compounds in order to find one that is effective against a particular target. Human cells are costly to take care of and require a lot of time and specific conditions in order to grow. Now researchers say that fission yeast may be used to find the next cancer cure.

Scientists show how plants turn a 'light switch' on and off
Scientists have uncovered the mechanisms through which cryptochrome 2 -- a key photoreceptor that allows plants to respond to blue light -- is switched on and off, allowing plants to remain responsive to light.

First atomic-level image of the human 'marijuana receptor' unveiled
In a discovery that advances the understanding of how marijuana works in the human body, an international group of scientists has, for the first time, created a three-dimensional atomic-level image of the molecular structure activated by tetrahydrocannabinol (THC), the active chemical in marijuana.

New evolutionary finding: Species take different genetic paths to reach same trait
Biologists have been contemplating evolutionary change since Charles Darwin first explained it. Using modern molecular tools and fieldwork, biologists have demonstrated for the first time that different species can take different genetic paths to develop the same trait.

Temperature, not predatory pressures, drives plankton abundance
Plankton blooms in spring are largely driven by temperature-induced increases in cell division, a new study reveals.
