Janaki Ammal (1897- 1984) was an Indian botanist known for her studies on plant breeding, genetics and cytogenetics. Her research on chromosome numbers in plants was crucial in selecting plants for cross-breeding and developing high-yielding varieties of sugarcane, eggplant, and magnolias.

Philipp Khaitovich works in Shanghai, a city that is developing at a pace as dramatic as his research field. This makes for an inspirational environment. At the CAS-MPG Partner Institute for Computational Biology, the molecular biologist is investigating how the different brain development of primates is linked to their age.
Research in China is no different than anywhere else in the world.
In her essay, Max Planck Director Ayelet Shachar describes how governments in western countries are increasingly attempting to control access to their territories far beyond the actual national borders and monitor the mobility of their own citizens. These efforts have been massively intensified with the spread of the corona pandemic. The legal expert warns that this must change as soon as the virus is defeated.

Astronomers led by Maria Bergemann (Max-Planck-Institute for Astronomy) have performed chemical measurements on stars that could markedly change the way cosmologists measure the Hubble constant and determine the amount of so-called dark energy in our universe. Using improved models of how the presence of chemical elements affects a star’s spectrum, the researchers found that so-called supernovae Type Ia have different properties than previously thought. Based on assumption about their brightness, cosmologists have used those supernovae to measure the expansion history of the universe. In light of the new results, it is now likely those assumptions will need to be revised.
Chemistry-wise, the universe started very simple, with almost nothing else but hydrogen
Although Gabriele Alex and Vibha Joshi belong to different departments at the Max Planck Institute for the Study of Religious and Ethnic Diversity in Göttingen, both scientists are studying the wide range of healing methods used and traditions followed in Indian society. Here they show from different perspectives how the supposed contradictions aren’t really all that incompatible in practice.

Parasites exist not only in the plant and animal kingdoms, they are also a part of us. Our genome contains myriad short stretches of DNA that propagate at the genome’s expense. For this reason, these transposons, as they are called, are also referred to as parasitic DNA. Oliver Weichenrieder from the Max Planck Institute for Developmental Biology in Tübingen wants to shed light on the processes by which transposons are copied – not only because they can cause disease, but also because they may be an important engine of evolution.

The violent conflict in Afghanistan has been escalating since 2005, making the process of reconstruction that much harder. To bring stability to the country, the focus must be on strengthening the state and facilitating the rule of law.

When different varieties of one plant species are crossed with each other, their hybrid offspring are often more robust and grow more quickly than their parents. However, in the next generation this effect disappears again. New methods make it possible to preserve the advantageous qualities of these kinds of hybrid plants for the long term and to deliberately design plants with four sets of chromosomes rather than two. The techniques should make it easier to breed particularly high-yielding and resistant crops that could feed a growing global population even in times of climate crisis.
But the botanist noticed something else too: the offspring thrived more than their
