Hunger encourages risk-taking
Hunger encourages risk-taking
Meta-analysis shows that in animals, difficult living conditions increase risk-taking behaviour in later life The lives of animals in the wild are full of risky situations with uncertain outcomes. Whether they are exploring new habitats in unfamiliar terrain or searching for new food sources, they run the risk of being caught and killed by a predator.

Can organic plant protection products damage crops?
Researchers at Göttingen University discover new disease affecting maize Protecting crops against pests and diseases is essential to ensure a secure food supply. Around 95 percent of food comes from conventional agriculture, which uses chemical pesticides to keep crops healthy. Increasingly, however, organic pesticides are also being sought as an alternative.

Stellar explosion in Earth's proximity
Stellar explosion in Earth’s proximity
Discovery of iron-60 and manganese-53 substantiates supernova 2.5 million years ago When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova - a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned to normal, physicists from the Technical University of Munich (TUM) have found evidence of a supernova that exploded near the Earth around 2.5 million years ago.

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.

Hand pollination, not agrochemicals, increases cocoa yield and farmer income
Hand pollination, not agrochemicals, increases cocoa yield and farmer income
Agroecologists from Göttingen University compare pesticides, fertilisers, manual pollination and farming costs in Indonesia Cocoa is in great demand on the world market, but there are many different ways to increase production. A research team from the University of Göttingen has now investigated the relative importance of the use of pesticides, fertilisers and manual pollination in a well replicated field trial in Indonesian agroforestry systems.

Looking at evolution’s genealogy from home
As the developers of 2-n-way, Dr. Jürgen Schmitz, Dr. Liliya Doronina, Norbert Grundmann, Fengjun Zhang and Dr. Gennady Churakov (from left) are delighted at the publication of their project in the specialist press. Evolution leaves its traces in particular in genomes. Pinpointing its influence is a laborious process - but one in which Dr. Jürgen Schmitz and his team at the University of Münster are at home.

Understanding What Holds Societies Together
Berlin University Alliance funds six groundbreaking projects in the Social Cohesion funding line of its Grand Challenge Initiatives No 170/2020 from Sep 28, 2020 Social cohesion is a global challenge. Understanding social transformations is a key to successful coexistence in a complex, heterogeneous world.

Secure nano-carrier delivers medications directly to cells
Secure nano-carrier delivers medications directly to cells
Nanoparticles with synthetic DNA can control release of drugs Medications often have unwanted side-effects. One reason is that they reach not only the unhealthy cells for which they are intended, but also reach and have an impact on healthy cells. Researchers at the Technical University of Munich (TUM), working together with the KTH Royal Institute of Technology in Stockholm, have developed a stable nano-carrier for medications.

New storage battery more efficient and heat-resistant
Chemists at the University of Jena develop new polymer electrolytes for redox flow batteries Light The share of energy from renewable sources is constantly on the rise in Germany. At the beginning of 2020, for the first time ever, renewable energy was able to cover more than half of the electricity consumed in Germany.

The Return of the Spin Echo
The Return of the Spin Echo
If the spins of phosphorus atoms in silicon are cleverly excited with microwave pulses, a so-called spin echo signal can be detected after a certain time. Surprisingly, this spin echo does not occur only once, but a whole series of echoes can be detected.

Broad beans versus soybeans as feedstuff for dual-purpose chickens
University of Göttingen research team investigates influence on meat quality Current practices of the poultry industry have raised ethical and ecological concerns: ethical concerns include the culling of day-old male chicks of egg-laying breeds; ecological concerns include the import of large quantities of soybeans for feedstuff.

Genome Duplications as Evolutionary Adaptation Strategy
Genome duplications play a major role in the development of forms and structures of plant organisms and their changes across long periods of evolution. Heidelberg University biologists under the direction of Marcus Koch made this discovery in their research of the Brassicaceae family. To determine the scope of the different variations over 30 million years, they analysed all 4,000 species of this plant family and investigated at the genus level their morphological diversity with respect to all their characteristic traits.

Ecologists confirm Alan Turing’s theory for Australian fairy circles
International research team led by Göttingen University shows patterned vegetation regenerates by -ecosystem engineering- of the grasses Fairy circles are one of nature's greatest enigmas and most visually stunning phenomena. An international research team led by the University of Göttingen has now, for the first time, collected detailed data to show that Alan Turing's model explains the striking vegetation patterns of the Australian fairy circles.
