Evolution of walking leaves
Evolution of walking leaves
Göttingen research team creates phylogenetic tree of leaf insects An international research team led by the University of Göttingen has studied the evolution of the walking leaves. Walking leaves belong to the stick insects and ghost insects that, unlike their approximately 3,000 branch-like relatives, do not imitate twigs.

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.

Solar-powered microbes to feed the world?
International research team shows that protein from microbes uses a fraction of the resources of conventional farming Microbes have played a key role in our food and drinks - from cheese to beer - for millennia but their impact on our nutrition may soon become even more important. The world is facing growing food challenges as the human population continues to increase alongside its demand for resource intensive animal products.

New strategy against sepsis
New strategy against sepsis
Some cases of bloodstream infections are mild, but many have a fatal outcome - the reasons for these differences have remained in the dark despite decades of research. Researchers from the Cluster of Excellence "Controlling Microbes to Fight Infections" (CMFI), the Interfaculty Institute of Microbiology and Infection Medicine Tübingen (IMIT) at the University of Tübingen and the German Center for Infection Research (DZIF) have now discovered a possible cause and on this basis developed a new experimental strategy to combat bacterial sepsis.

Spin-sonics: Acoustic wave gets the electrons spinning: Team of researchers first to demonstrate spin of a nano-sonic wave
Spin-sonics: Acoustic wave gets the electrons spinning: Team of researchers first to demonstrate spin of a nano-sonic wave
A team of German and American researchers from Augsburg, Münster, Edmonton, West Lafayette and Munich have detected the rolling movement of a nano-acoustic wave predicted by the famous physicist and Nobel prize-winner Lord Rayleigh in 1885. In a study published in the journal "Science Advances", the researchers use a nanowire inside which electrons are forced onto circular paths by the spin of the acoustic wave.

Energy for undisturbed rest
Energy for undisturbed rest
07/29/2021 In the fruit fly Drosophila, a hormone helps to balance rest and activity. This is shown by a new study of a research team led by the University of Würzburg. Might humans have a hormone with comparable function? Searching for food, eating, resting: in rough terms, this is the rhythm of life that many animals follow.

New regulators of the aging process
New regulators of the aging process
The attachment of the small protein ubiquitin to other proteins (ubiquitination) regulates numerous biological processes, including signal transduction and metabolism / Scientists at the University of Cologne discover the link to aging and longevity / Publication in 'Nature'. Scientists have discovered that the protein ubiquitin plays an important role in the regulation of the aging process.

First synthetic tissue model developed in which blood vessels can grow
First synthetic tissue model developed in which blood vessels can grow
Researchers investigate which material properties support vessel formation / Study published in the journal "Nature Communications" Using lab-created tissue to heal or replace damaged organs is one of the great visions for the future of medicine. Synthetic materials could be suitable as scaffolding for tissue because, unlike natural tissues, they remain stable in the organism long enough for the body to form new natural structures.

Model developed to predict the effect of antibody treatment in HIV infection
The dosage of broadly neutralizing antibodies determines the ability for virus replication / findings can contribute to design HIV therapy that can durably suppress the virus A Cologne-based research collaboration has found a way to predict the effect of broadly neutralizing antibodies (bnAbs) on the growth rate of HIV-1.

Animals are better sprinters
An interdisciplinary group of scientists from the universities of Cologne, Koblenz, Tübingen, and Stuttgart has studied the characteristics determining the maximum running speed in animals. The model they developed explains why humans cannot keep up with the fastest sprinters in the animal kingdom. Based on these calculations, the giant spider Shelob from 'The Lord of the Rings' would have reached a maximum speed of 60 km/h.

Stone tool tells the story of Neanderthal hunting
Stone tool tells the story of Neanderthal hunting
65,000 years ago Neanderthal from the Swabian Jura hunted horses and reindeer with hafted leaf-shaped stone points. A newly discovered leaf point from the UNESCO World Heritage site of Hohle Fels Cave documents the evolution of hunting. A team under the direction of Professor Nicholas Conard for the University of Tübingen and the Senckenberg Centre for Human Evolution and Palaeoenvironment in southern Germany recovered the artifact underlying a layer dating to 65,000 years ago, which represents a minimum age for the find.

Silicon with a Two-Dimensional Structure
Silicon with a Two-Dimensional Structure
Heidelberg chemists succeed in producing synthesis and complete characterisation for the first time Silicon, a semi-metal, bonds in its natural form with four other elements and its three-dimensional structure takes the form of a tetrahedron. For a long time, it seemed impossible to achieve the synthesis and characterisation of a two-dimensional equivalent - geometrically speaking, a square.

Eco-friendly plastic from cellulose and water
Göttingen researchers create new kind of environmentally friendly bioplastic with hydroplastic polymers Plastics offer many benefits to society and are widely used in our daily life: they are lightweight, cheap and adaptable. However, the production, processing and disposal of plastics are simply not sustainable, and pose a major global threat to the environment and human health.

Long-period oscillations of the Sun discovered
Ten years of data from NASA's Solar Dynamics Observatory combined with numerical models reveal the deep low musical notes of the Sun   (mps) A team of solar physicists led by Professor Laurent Gizon of the Max Planck Institute for Solar System Research (MPS) and the University of Göttingen in Germany has reported the discovery of global oscillations of the Sun with very long periods, comparable to the 27-day solar rotation period.

Cancer development is influenced by tissue type
Cancer development is influenced by tissue type
Why identical mutations cause different types of cancer Why do alterations of certain genes cause cancer only in specific organs of the human body? Scientists have now demonstrated that cells originating from different organs are differentially susceptible to activating mutations in cancer drivers: The same mutation in precursor cells of the pancreas or the bile duct leads to fundamental different outcomes.

Simplified method for calibrating optical tweezers: Broadband measurement of viscoelasticity with reduced measurement time
Measurements of biomechanical properties inside living cells require minimally invasive methods. Optical tweezers are particularly attractive as a tool. It uses the momentum of light to trap and manipulate microor nanoscale particles. A team of researchers led by Cornelia Denz from the University of Münster has now developed a simplified method to perform the necessary calibration of the optical tweezers in the system under investigation.
