Watch white blood cells as they scurry along blood vessels and descend upon an injury site.

Visualizing proteins is crucial for understanding normal cell function.

Microbes share and preserve their genetic material by releasing bodies that resemble viruses into the environment

A former postdoctoral fellow at Washington State University has reportedly falsified data presented in two figures of an epigenetics paper, according to the Office of Research Integrity (ORI) linkurl:report;http://ori.hhs.gov/misconduct/cases/Chang_Hung-Shu.shtml released late last month.

Parasite's unusual metabolism __Plasmodium falciparum__ may have evolved a unique, non-cyclic version of the textbook energy-producing process in cells known as the Krebs cycle -- presumably as an adaptation to living inside human blood cells -- a finding that could lead to new Malaria drug targets.

An international group of researchers have developed a novel method for identifying entire networks of genes and their association to disease, providing a more accurate picture of the genetic risks associated with specific diseases than single genes can provide.Photo: linkurl:Joanna Servaes;http://joanna-servaes.magix.net via Wikimedia Commons In the proof-of-concept paper published today (8th September) in __Nature__, the researchers used an integrated genomics approach to identify a network o

From the automata of the ancient Greeks, to the curious mechanical inventions of the Age of Enlightenment, people have been creating robotic renderings of animals for centuries. It was only recently, however, that technology advanced enough to produce sophisticated robots that biologists can use for studying animal behavior. By mimicking specific behaviors with striking realism, these robots can stand in for (and fool) their living counterparts -- thus offering researchers the one thing that's o
