How much forest does biodiversity need in cultivated landscapes?
How much forest does biodiversity need in cultivated landscapes?
Research team with Göttingen participation develops concepts to promote biodiversity Forests, especially in the tropics, are home to the world's greatest biodiversity, but are threatened by increasing land use. An international research team with participation of the University of Göttingen has investigated how high the proportion of forest in cultivated landscapes must be in order to protect the greatest number of animal and plant species that depend on this habitat.

Hormone systems can still be adapted in adulthood
Hormone systems can still be adapted in adulthood
How do animals adapt their behaviour during life in order to assure survival and reproduction? This is a question of great interest for behavioural biologists worldwide. An essential step is to examine hormonal mechanisms which have a fundamental impact on the animal's behaviour and thus make adaptations to various social situations possible.

The psychology behind toilet paper hoarding
The psychology behind toilet paper hoarding
Following the rapid spread of COVID-19 in Europe and North America in March 2020, many people around the world began hoarding goods such as toilet paper. Some companies reported an increase in toilet paper sales of up to 700 percent, despite calls from governments to refrain from "panic buying". Which groups of people primarily hoarded all the toilet paper? Psychologists from the universities of St. Gallen and Münster and the Max Planck Institute for Evolutionary Anthropology in Leipzig investigated this question.

Coffee, cocoa and vanilla: an opportunity for more trees in tropical agricultural landscapes
Coffee, cocoa and vanilla: an opportunity for more trees in tropical agricultural landscapes
Research team from Göttingen University investigates the land-use history of agroforestry systems The cultivation of coffee, cocoa and vanilla secures the income of many small-holder farmers and is also a driver of land-use change in many tropical countries. In particular, cultivation in agroforestry systems, in which these crops are combined with trees that provide shade, is often considered to have great potential for ecologically sustainable cultivation.

Radioactive cloud over Europe had civilian background: Isotope measurements on air filters
Radioactive cloud over Europe had civilian background: Isotope measurements on air filters
A mysterious cloud containing radioactive ruthenium-106, which moved across Europe in autumn 2017, is still bothering Europe's radiation protection entities. Although the activity concentrations were innocuous, they reached up to 100 times the levels of what had been detected over Europe in the aftermath of the Fukushima accident.

Protecting scientific diversity
International researchers demand the active protection and support of diversity, equity and inclusion in science In the course of the COVID-19 pandemic, scientists are facing great challenges because they have to reorient, interrupt or even cancel research and teaching.

Forces in the Earth's crust determine the height of mountain ranges
Forces in the Earth’s crust determine the height of mountain ranges
Geoscientists show that it is not erosion but an equilibrium of forces in the Earth's crust that controls the "growth" of mountains / Study in "Nature" Which forces and mechanisms determine the height of mountains? Researchers at the University of Münster and the German Research Centre for Geoscience (GFZ) in Potsdam have now found a surprising answer: It is not erosion and weathering of rocks that determine the upper limit of mountain belts, but rather an equilibrium of forces in the Earth's crust.

New Strategies for Virus Inhibition
Highly flexible or spiky nanosystems by Berlin researchers open the door for new antiviral options against influenza viruses No 098/2020 from Jun 11, 2020 Berlin researchers have applied two new strategies based on multivalent nanosystems for making influenza A viruses (IAV) innocuous. The decisive factor in the development of these new strategies against influenza was the cooperation between scientists from different disciplines - chemistry, physics, virology, and imaging - the collaborative partners of Freie Universität Berlin, Humboldt University Berlin, and the Robert Koch Institute.

Researchers identify "hot spots" for developing lymphatic vessels: Experiments on zebrafish
Experiments on zebrafish: fibroblasts produce important enzyme-processing proteins triggering growth in vessels / Study in "Nature Communications" When an embryo develops, a wide variety of proteins and enzymes trigger a series of biochemical reactions. The development of the lymphatic vasculature is crucially dependent on one specific protein - the growth factor VEGF-C.

A newly discovered disease may lead to better treatment of cystic fibrosis
Cystic fibrosis is the most frequent severe inherited disorder worldwide. Every year, hundreds of families are confronted with this diagnosis - and to date, there is no cure for this disease that mainly affects the respiratory system. Besides supportive treatments, a lung transplant is often the only option to save a patient's live.

View into plant cells: A membrane protein is targeted to two locations
Metabolic processes are especially complex in plants due to their obligate sessile life style - which is why scientists discover more and more new and surprising connections that occur within their cells. An important metabolic route that has occupied plant scientists for decades is the so-called oxidative pentose-phosphate pathway by which carbohydrates are converted to reduction power.

Protecting the Neuronal Architecture
Protecting nerve cells from losing their characteristic extensions, the dendrites, can reduce brain damage after a stroke. Neurobiologists from Heidelberg University have demonstrated this by means of research on a mouse model. The team, led by Hilmar Bading in cooperation with Junior Professor Dr Daniela Mauceri, is investigating the protection of neuronal architecture to develop new approaches to treating neurodegenerative diseases.

’Whispering gallery’ effect controls electron beams with light
Research team led by the University of Göttingen succeeds in coupling free electrons to optical resonators When you speak softly in one of the galleries of St Paul's cathedral, the sound runs so easily around the dome that visitors anywhere on its circumference can hear it. This striking phenomenon has been termed the -whispering gallery- effect, and variants of it appear in many scenarios where a wave can travel nearly perfectly around a structure.

Remdesivir effective against Covid-19 even after short treatment periods
Comparable clinical results after five and ten days of treatment In an international study, scientists from eight countries have investigated the use of the medication Remdesivir in the treatment of Covid-19. One result of the study, which included the participation of the Technical University of Munich's university hospital TUM Klinikum rechts der Isar: The changes in the clinical condition of patients treated for five days were comparable to the changes in patients treated for a period of ten days.

The forest is changing
Globally, forests are increasingly under pressure. Climatic extremes such as heat and drought are major stress factors for them. A study in cooperation with the Technical University of Munich (TUM) and published in Science is examining, how global change may affect forests in the future. The researchers present potential scenarios of future forest development and thereby offer important information for forest policy and management.

Selectively Reactivating Nerve Cells to Retrieve a Memory
Selectively increasing the levels of a certain protein in nerve cells that play a key role in memory storage boosts memory performance, as demonstrated in experiments on mice by a group of scientists at Heidelberg University led by Dr Ana Oliveira. The responsible protein is Dnmt3a2 - a so-called epigenetic factor that chemically modifies the genome and thus influences memory processes.

Triggered by light, a novel way to switch on an enzyme: Biotechnology
Triggered by light, a novel way to switch on an enzyme: Biotechnology
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. A topic that is currently being widely discussed is photoinduced catalysis, in which researchers harness the ability of nature to start biochemical reactions with the aid of light.
