Altered sugar composition impacts cell-to-surface adhesion

Biotechnologists measure the forces with which algae cells adhere to surfaces and move on them. How can cells adhere to surfaces and move on them? This is a question that was investigated by an international team of researchers headed by Prof. Michael Hippler from the University of Münster and Prof. Kaiyao Huang from the Institute of Hydrobiology (Chinese Academy of Sciences, Wuhan, China).

Scientists develop novel approach to acquire fluorescence lifetime images

Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light within a specific wavelength range and then re-emit it at the longer wavelength range.

High-speed atomic force microscopy sheds light on structure, dynamics of intrinsically disordered proteins

Kanazawa University’s pioneering high-speed atomic force microscope technology has now shed light on the structure and dynamics of some of life’s most ubiquitous and inscrutable molecules – intrinsically disordered proteins.

Highly developed microscopy methods can help detect antigens

Highly complicated processes constantly take place in our body to keep pathogens in check: The T-cells of our immune system are busy searching for antigens - suspicious molecules that fit exactly into certain receptors of the T-cells like a key into a lock. This activates the T-cell and the defense mechanisms of the immune system are set in motion.

Novel microscope could allow surgeons to inspect cancer margins in minutes

When surgeons remove cancer, one of the first questions is, "Did they get it all?" Researchers from Rice University and the University of Texas MD Anderson Cancer Center have created a new microscope that can quickly and inexpensively image large tissue sections, potentially during surgery, to find the answer.

Research clarifies regulatory impacts of ubiquitin-proteasome system on DNA damage repair

An international research team has clarified the regulatory mechanism of the ubiquitin-proteasome system (*1) in recognizing and repairing DNA that has been damaged by ultraviolet (UV) light.

Researchers discover molecular mechanism of plant immune receptors

In a recent study, Alexander von Humboldt Professor Jijie Chai at the University of Cologne and his team together with MPIPZ researchers have succeeded for the first time in reconstructing the sequence of molecular events that activate an inactive plant immune receptor and thus mediate the death of the host cell.
