Boulder, CO, USA. A new prototype bioreactor — a device for culturing cells to create engineered tissues — evaluates the engineered tissue during its creation.

The bioreactor both stimulates and evaluates tissue as it grows, mimicking natural processes while eliminating the need to stop periodically to cut up samples for analysis.

Leicester, UK. Scientists observing the architecture within a cell have seen for the first time how it changes during gamete (sex cell) formation to complete the process.

The investigators expect that the information obtained researching yeast cells will bring novel insights into the basic mechanisms of cellular regulation, which may be applicable to higher organisms including humans.

Sheffield, England. Evidence shows humans continue to evolve and that significant natural and sexual selection is still taking place in our species throughout the world.

Despite advancements in medicine and technology that many people believe can alter the human trajectory, as well as an increased prevalence of monogamy, research reveals humans are continuing their evolution just like other species.

Atlanta, GA, USA. Compressed sensing has provided super-resolution plus faster temporal resolution, resulting in a clear picture of a single cellular structure in motion.

Despite many achievements in the field of super-resolution microscopy in the past few years with spatial resolution advances, live-cell imaging has been challenging because of the need for high temporal resolution.

Oslo, Norway. Our most remote relative lives down in the sludge bottom of a little lake south of Oslo in Norway and represents a previously unknown branch of the tree of life.

Biologists worldwide have eagerly awaited the results of the genetic analysis of a very rare micro-organism, one of the world's smallest known species (hereafter called the protozoan) that may provide insights into what life looked like on earth almost one thousand million years ago.
