New finds at temple city of Heliopolis
New finds at temple city of Heliopolis
During recently completed excavations in northeastern Cairo, an Egyptian-German excavation team of archaeologists has found important evidence from the history of the temple city of Heliopolis. It includes the foundation of a limestone wall, which was discovered running from north to south about 55 metres west of the still-standing obelisk of Heliopolis.

Safe singing in choirs during pandemics
Safe singing in choirs during pandemics
In order to investigate how aerosols, as possible carriers of viruses, are distributed in the room during a choir rehearsal, research teams from the University of Leipzig and the TU Bergakademie Freiberg carried out measurements during choir rehearsals in recent months. The researchers now report on their findings in the Journal of Voice.

Identifying 'lazy' and 'industrious' Cells in Biocatalysis
Identifying ’lazy’ and ’industrious’ Cells in Biocatalysis
Breakthrough in tracking biocatalysis by single cells opens up new possibilities in "green chemistry" The transformation of chemical compounds by living cells - so-called whole-cell biocatalysts - is a process that has been known for some time and has led to a wealth of interesting products. This is evident, for example, in traditional processes such as bread baking or beer brewing, where molecules produced by yeast fungi contribute significantly to flavor.

The largest genomic catalogue of wild chimpanzees
New genomic tools shed light on the evolutionary history of chimpanzees and contribute to their conservation An international research team led by the Institute of Evolutionary Biology (IBE), the German Centre for Integrative Biodiversity Research (iDiv), the Max Planck Institute for Evolutionary Anthropology (MPI EVA) and Leipzig University has compiled the largest genomic catalogue of wild chimpanzee populations in Africa.

Biosynthesis of cyanobacterin opens up new class of natural compounds
Biosynthesis of cyanobacterin opens up new class of natural compounds
Researchers in the groups of Prof. Tobias Gulder from TU Dresden and Prof. Tanja Gulder from Leipzig University have succeeded in understanding the biosynthetic mechanisms for the production of the natural product cyanobacterin, which in Nature is produced in small quantities by the cyanobacteria Scytonema hofmanni.

Corals as climate archives
Unusually well-preserved reef corals from the Geological and Palaeontological Collection at Leip-zig University hold a great secret: they allow us to travel far into the past and reconstruct climatic conditions in our latitudes. Researchers from Leipzig University, the Universities of Bremen and Greifswald, and UniLaSalle in Beauvais have now succeeded in doing just this.

Newly discovered enzyme breaks down PET plastic in record time
Research finding from Leipzig could help make biological recycling more commercially viable Plastic bottles, punnets, wrap - such lightweight packaging made of PET plastic becomes a problem if it is not recycled. Scientists at Leipzig University have now discovered a highly efficient enzyme that degrades PET in record time.

Rare discovery: How a gene mutation causes higher intelligence
Rare discovery: How a gene mutation causes higher intelligence
When genes mutate, this can lead to severe diseases of the human nervous system. Researchers at Leipzig University and the University of Würzburg have now used fruit flies to demonstrate how, apart from the negative effect, the mutation of a neuronal gene can have a positive effect - namely higher IQ in humans.

Small changes - but essential! How peptides are recognised in receptors
Small changes - but essential! How peptides are recognised in receptors
Researchers discover molecular mechanisms of signal recognition of the neuropeptide system The human body consists of trillions of cells that constantly communicate with each other. A central role in this communication process is played by receptor proteins on the cell surface. Since they often serve as drug targets, they have been the subject of intensive research.

How mechanical stimuli trigger cellular signalling
International GPCR research collaboration deciphers structure of active receptors Breathing, seeing, hearing - the family of G protein-coupled receptors (GPCRs) is involved in a variety of physiological processes and is also the cause of diverse diseases. As has now been discovered by a team of scientists led by Professor Ines Liebscher from Leipzig University, some members of the GPCR family respond to mechanical stimuli.

European earthworms reduce insect populations in North American forests
European earthworms reduce insect populations in North American forests
Researchers recommend taking underappreciated factors for biodiversity loss into account Earthworms introduced into northern North America have a negative impact on the insect fauna above ground. Soil ecologists, led by the German Centre for Integrative Biodiversity Research (iDiv) and Leipzig University describe this observation in the journal Biology Letters.

Chemotherapy or not? Physicists study gene expression tests
Following surgery, patients with breast cancer are faced with the question of whether additional chemotherapy is necessary and really effective. It is important that these women do not receive too much treatment - but not too little treatment either. Physicists from Leipzig University modelled the gene expression tests and examined their usefulness on the basis of these models.

New thermofluidic process for lab-on-a-chip applications
New thermofluidic process for lab-on-a-chip applications
Researchers at Leipzig University have succeeded in moving tiny amounts of liquid at will by remotely heating water over a metal film with a laser. The currents generated in this way can be used to manipulate and even capture tiny objects. This will unlock groundbreaking new solutions for nanotechnology, the manipulation of liquids in systems in tiny spaces, or in the field of diagnostics, by making it possible to detect the smallest concentrations of substances with new types of sensor systems.

Genome of Steller’s Sea Cow Decoded
During the Ice Age, giant mammals such as mammoths, sabre-toothed cats and woolly rhinoceroses once roamed Northern Europe and America. The cold oceans of the northern hemisphere were also home to giants like Steller's sea cow, which grew up to eight metres long and weighed up to ten tonnes, and has been extinct for around 250 years.

Intensive Land Management Impairing Ecosystem Interactions
Intensive Land Management Impairing Ecosystem Interactions
High land-use intensity reduces the beneficial effects of biodiversity on ecosystem services. This is the main result of a study conducted by an international team led by researchers from the Helmholtz Centre for Environmental Research (UFZ), the German Centre for Integrative Biodiversity Research (iDiv) and the University of Bern.

Shifts in Flowering Phases of Plants Due to Reduced Insect Density
Shifts in Flowering Phases of Plants Due to Reduced Insect Density
It still sounds unlikely today, but declines in insect numbers could well make it a frequent occurrence in the future: fields full of flowers, but not a bee in sight. A research group of the University of Jena and the German Centre for Integrative Biodiversity Research (iDiv) has discovered that insects have a decisive influence on the biodiversity and flowering phases of plants.

Artificial Intellegence Can Help Protect Orchids
Artificial Intellegence Can Help Protect Orchids
Orchids may be decorative, but many orchid species are also threatened by land conversion and illegal harvesting. However, only a fraction of those species are included in the IUCN Red List of Threatened Species, because assessments require a lot of time, resources and expertise. A new approach, an automated assessment developed under the lead of biodiversity researchers from Central Germany, now shows that almost 30 per cent of all orchid species are possibly threatened.

Downward Trend Is Reversible
Downward Trend Is Reversible
Ambitious, integrated action combining conservation and restoration efforts with a transformation of the food system. This is the recipe for turning the tide of biodiversity loss by 2050 or earlier, a new study led by the International Institute for Applied Systems Analysis (IIASA) with participation of researchers from the German Centre for Integrative Biodiversity Research (iDiv) suggests.
