Study analyzes technologies’ climate efficiency in removing carbon dioxide from the atmosphere

One process has similar CO2 footprint to e-mobility

02-Nov-2021

Technologies for the removal of carbon dioxide (CO2) from the atmosphere (direct air capture, or DAC for short) are already in use, but neither their actual benefits for climate protection nor their other environmental impact have yet to be investigated. A research team led by Kavya Madhu and ...

Crucial step identified in the conversion of biomass to methane

Researchers find the enzymatic link in the formation of methane from fatty acids by cooperating microorganisms

05-Oct-2021

Microbial production of methane from organic material is an essential process in the global carbon cycle and an important source of renewable energy. This natural process is based on a cooperative interaction between different types of microorganisms: the fermenting bacteria and the ...

Bacteria can boost the fitness of their host

01-Oct-2021

Microorganisms can increase their host’s ability to adapt to the environment and reproduce – evolutionary biologists are now studying the underlying molecular mechanisms. A research team headed by Dr. Fabian Staubach and Yun Wang from the Institute of Biology I at the University of Freiburg has ...

Novel strategy for natural product biosynthesis

Researchers discover enzyme prototype for formation of ecologically and pharmaceutically important tropone compounds

06-Jul-2021

Microorganisms produce natural products, for example, as disease-causing virulence factors or as defense substances against predators and competitors. A team led by Dr. Robin Teufel and first author Ying Duan from the Institute of Biology II at the Faculty of Biology of the University of ...

A remote control for gene transfer

Researchers develop technology to introduce genes into single cells in a targeted manner

18-Jun-2021

The ability to insert desirable genes into animal or human cells is the basis of modern life science research and of widespread biomedical applications. The methods used to date for this purpose are mostly non-specific, making it difficult for scientists to control which cell will or will not ...

A gene provides both protection and destruction

Researchers discover new function of the widely disseminated, yet little understood ENDOU enzyme

01-Mar-2021

The family of ENDOU enzymes is found in most organisms, yet its functions are only poorly understood. In humans, it has been connected with cancer. RNA viruses, such as SARS-CoV2, contain a gene corresponding to ENDOU, and this is important for virus replication and the suppression of the immune ...

Hierarchical dynamics

Researchers investigate signal transduction in proteins on many time scales

05-Feb-2021

A tree moving in the wind: How long does it take for the movement of a branch to reach the tree trunk? And via which pathway is this movement transmitted? Researchers at Albert Ludwig University are applying these questions to proteins, the molecular machinery of the cell. A team led by Prof. Dr. ...

A Small Protein in Bacteria Overlooked Up to Now

Researchers identify an essential factor involved in the ordered recycling of phycobilisome light-harvesting structures

02-Feb-2021

The biological process of photosynthesis is found at the beginning of nearly all food chains. It produces oxygen to breathe and provides the energetic foundation for using biotechnological processes to synthesize biofuels and chemical feedstock. Therefore, researchers are particularly interested ...

Common Vulnerabilities of Coronaviruses

International study maps molecular targets for possible therapy for MERS, SARS-CoV1, and SARS-CoV2

19-Oct-2020

In search of new drugs against COVID-19, a group of around 200 scientists is uncovering the molecular processes with which the coronaviruses MERS, SARS-CoV1, and SARS-CoV2 manipulate the host cell. The researchers from six countries have found 73 human proteins with which components of all three ...

Mechanism that causes cell nuclei to grow discovered

24-Sep-2020

By far the most important process in cell development is how cells divide and then enlarge in order to multiply. A research team headed by Freiburg medical scientist Prof. Dr. Robert Grosse has now discovered that bundled fibers of actin within a cell nucleus play an important part in how they ...
