Bird communities threatened by urbanization
Bird communities threatened by urbanization
Research team led by Göttingen University investigates farmland birds in an Indian megacity Urbanization is one of the most drastic forms of land-use change, and its negative consequences on biodiversity have been studied extensively in temperate countries such as Germany. However, less research has been conducted in tropical regions from the Global South, where most of the ongoing and future urbanization hotspots are located, and little is known about its effects on agricultural biodiversity and associated ecosystems.

New approach identifies T cells in Covid-19 patients
New approach identifies T cells in Covid-19 patients
Immune cell profile reveals appearance, number and activity level against SARS-CoV-2 T cells play a decisive role in fighting the coronavirus and preventing infected individuals from becoming seriously ill. They identify and fight the virus directly within the infected cells. A team of researchers working in Munich have produced a precise profile of the T cells that respond to SARS-CoV-2 and described them at various stages of the illness.

History of the spread of pepper is an early example of global trade
History of the spread of pepper is an early example of global trade
International research team conducted a genomic scan of thousands of pepper samples from around the world Pepper has flexible features like easily preserved and transportable in dried form, needed in moderate quantity to enrich dishes, easy to produce and wide scale. Genetic data stored in genebanks confirm that pepper has been spread along with the very earliest intercontinental traders, being among the first examples of a globally traded, mass-market, consumer-discretionary good.

Bacterial toxin blinds algae
Bacterial toxin blinds algae
Jena research team discovers natural product from soil bacteria that kills algae University of Jena researchers have discovered a bacterial toxin that destroys the colour pigments in the eyespot of the single-cell green alga Chlamydomonas reinhardtii. Together with another toxic substance, the bacteria of the species Pseudomonas protegens not only disorientate and immobilise the green algae, but condemn them to a certain death.

Virtual experiments: Münster University geophysicists research the Earth’s origins on the computer
Although Dr. Christian Maas does his research only on the computer, it's sometimes as if he were standing in a laboratory. "I do experiments," he says. By means of his virtual experiments, geophysicist Maas is investigating a question that couldn't be answered in any lab in the world: the question of the how the Earth came into being.

Taking aim at skin bacteria
Taking aim at skin bacteria
Enzyme treatment of skin samples improves microbiome analysis Healthy skin has a bacterial shield to protect against germs: the microbiome. This complex assembly of microorganisms was previously believed to be difficult to decipher. A team of researchers has now succeeded in using the enzyme benzonase to identify the living bacteria in skin swabs through sequencing.

Qubits Under Pressure
Qubits Under Pressure
A new type of atomic sensor made of boron nitride is presented by researchers in "Nature Communications". The sensor is based on a qubit in the crystal lattice and is superior to comparable sensors. An artificially created spin defect (qubit) in a crystal lattice of boron nitride is suitable as a sensor enabling the measurement of different changes in its local environment.

Study tracks global death toll of COVID-19 pandemic
Comparing the impact of COVID-19 between countries or during a given period of time is challenging because reported numbers of cases and deaths can be affected by testing capacity and reporting policy. The current study provides a more accurate picture of the effects of COVID-19 than using these numbers, and may improve our understanding of this and future pandemics.

Combination vaccines against Covid-19 tested
Immune response stronger than after two doses of AstraZeneca vaccine People under the age of 60 who initially received a vaccine from AstraZeneca should be given an mRNA vaccine at their second appointment. This is recommended by the German Standing Committee on Vaccination. However, up until now, there were no data available to indicate to what extent the human organism would react to such a combined vaccination and start to form antibodies.
