How Human Derived RNA Fragments Help the Hepatitis E Virus
How Human Derived RNA Fragments Help the Hepatitis E Virus
If the virus incorporates host genetic segments into its genome, the infection may become chronic. Why does Hepatitis E become chronic in some patients, and why do medications not work? To find out, an international research team led by scientists from Bochum observed a patient with chronic Hepatitis E infection over a year.

Rodents inspire dentistry
Rodents inspire dentistry
Researchers discover an iron-containing material in the outer enamel of rodent teeth that could also make human teeth more resistant   Rodents such as beavers, nutrias (coypu) , squirrels and rats have particularly strong, elongated front teeth that grow continuously over the course of their lives. Using state-of-the-art imaging techniques, researchers at the Max Planck Institute for Solid State Research in Stuttgart have now elucidated the tooth structure of various rodent species at the nanometre scale.

Perturbations simplify the study of 'super photons'
Perturbations simplify the study of ’super photons’
A study by the University of Bonn gives novel insight into properties which are often difficult to observe Thousands of particles of light can merge into a type of "super photon" under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers at the University of Bonn have now shown that this exotic quantum state obeys a fundamental theorem of physics.

Second great ape species discovered at Hammerschmiede fossil site
Second great ape species discovered at Hammerschmiede fossil site
An international team of researchers has discovered a previously unknown ape species in the Hammerschmiede clay pit in southern Germany. Buronius manfredschmidi was found close to the great ape Danuvius guggenmosi , known as "Udo". This was about 12 million years ago the first ape with adaptations for walking upright and made the Hammerschmiede excavation site famous.

How nature repurposes ammonium transporters as receptors
How nature repurposes ammonium transporters as receptors
Research team at the University of Freiburg identifies new membrane protein Sd-Amt1 A team led by Freiburg biochemist Susana Andrade has characterised a new membrane protein that allows microorganisms to repurpose ammonium transporters (Amts) as receptors. Ammonium transporters clearly distinguish between ammonium, potassium and water.

Key to Improving Cancer Treatments Discovered
Key to Improving Cancer Treatments Discovered
Some cancer drugs cause severe side effects because they are not working accurately enough. A team at the University of Würzburg led by biochemist Caroline Kisker has now discovered why. The small protein ubiquitin is involved in almost every cellular process in our body: it orchestrates the stability and function of the vast majority of proteins.

Tracking the Climate With the Help of Blue-Green Algae
Led by the University of Bremen, RWTH paleoclimate researcher Professor Thorsten Bauersachs and colleagues have now published their results on the glaciation of West Antarctica in the journal Science Advances. It has been more than 30 million years since West Antarctica was last largely ice-free. In the last 30 million years, however, it has been extensively glaciated.

Restless legs syndrome: new approaches for treatment
Restless legs syndrome: new approaches for treatment
Largest genetic study on RLS to date An international team of researchers from the Technical University of Munich (TUM) and Helmholtz Munich has conducted the largest genetic investigation of restless legs syndrome (RLS) to date. The study represents a significant advancement in deciphering the genetic basis of this disorder and opens novel pathways for patient care.

Blood vessels are the pioneers of bone formation in the skull
Blood vessels are the pioneers of bone formation in the skull
Living bone is fascinating because of its unique ability to adapt to mechanical stress and regenerate without scarring. During fracture healing, blood vessels and bone cells work closely together to gradually replace the initial cartilaginous wound tissue with ingrowing blood vessels and new bone tissue.

Earliest manuscript of Gospel about Jesus's childhood discovered
Earliest manuscript of Gospel about Jesus’s childhood discovered
Papyrologists decipher manuscript fragment and date it to the 4th to 5th century. For decades, a papyrus fragment with the inventory number P.Hamb.Graec. 1011 remained unnoticed at the Hamburg Carl von Ossietzky State and University Library. Now papyrologists Dr Lajos Berkes from the Institute for Christianity and Antiquity at Humboldt-Universität zu Berlin (HU), and Prof Gabriel Nocchi Macedo from the University of Liège, Belgium, have identified the fragment as the earliest surviving copy of the Infancy Gospel of Thomas .

Medieval game collection unearthed
Medieval game collection unearthed
A team of archaeologists discovers an almost 1.000-year-old games collection including a well-preserved chessman, gaming pieces and dice. Laboratory analyses show that one party played with red. The laboratory results also allow conclusions to be drawn about the astonishing continuity of the rules of the game.

Paving the Way for Hydrogen from Algae Enzymes
Paving the Way for Hydrogen from Algae Enzymes
A research team from Bochum has identified a crucial detail that's essential for the production of hydrogen using biocatalysts. Under certain conditions, some algae are able to produce hydrogen - a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present.

The Route Into the Cell Influences the Outcome of Sars-Cov-2 Infection
The Route Into the Cell Influences the Outcome of Sars-Cov-2 Infection
A surface protein helps viruses to enter cells. This has far-reaching consequences for the infection. How exactly do Sars-Cov-2 particles enter host cells? An international team led by Dr Richard Brown from Dr Daniel Todt's Computational Virology group at the Department of Molecular and Medical Virology at Ruhr University Bochum, Germany, together with researchers from the Paul-Ehrlich-Institut, investigated this question.

Visiting flowers and transporting pollen in fragmented landscapes
Research team compares wild bee networks at a small scale and at landscape level   Traditionally, interactions between plants and their pollinators are analysed on the basis of visits to flowers. A research team led by the University of Göttingen studied wild bees on chalk grassland. The researchers analysed both the networks showing visits to flowers and the networks where pollen was transported.
