To improve existing antibiotics and develop new antimicrobial treatments
To improve existing antibiotics and develop new antimicrobial treatments
Recerca The lack of effective antibiotics is an increasingly serious threat to global health. In recent decades, only a few new antimicrobial agents have been able to reach the market. Designing new functionalities for already known antibiotics —or those that have fallen out of use due to toxicity— is one of the strategies to make up for this drug shortage.

Mechanical forces in the nervous system play a corrective role
Mechanical forces in the nervous system play a corrective role
Team of researchers at Münster University show in the fruit fly how mechanical tearing cut neural connections Nerve cells communicate with one another via long processes known as axons and dendrites, or, more generally, neurites. During development, these processes first grow and form connections with other cells, for example synapses with other nerve cells.

Dengue and Zika Viruses: Towards a Better Understanding of the Mechanisms of Transmission
Aedes mosquitoes are the principal vectors of dengue and other arboviruses, including Zika, for which no vaccines or antiviral treatments currently exist. Understanding the factors that influence the transmission of arboviruses from mosquitoes to humans is therefore a priority because it could guide the implementation of public health measures that could limit or even prevent epidemics.

What crocodile DNA reveals about the Ice Age
What crocodile DNA reveals about the Ice Age
Environmental drivers such as sea level affect genetic evolution and point to where conservation efforts may be focused What drives crocodile evolution? Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers from McGill University discovered that while changing temperatures and rainfall had little impact on the crocodiles- gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.

Thermal motions and oscillation modes determine the uptake of bacteria in cells
Thermal motions and oscillation modes determine the uptake of bacteria in cells
Team at the University of Freiburg analyzes how model bacteria dock to and penetrate membrane bubbles. How and with what effort does a bacterium - or a virus - enter a cell and cause an infection? Researchers from Freiburg have now made an important contribution to answering this question: A team led by physicist Alexander Rohrbach and his collaborator Dr. Yareni Ayala was able to show how thermal fluctuations of a model bacterium and membrane oscillation modes of a model cell influence the energy with which the model bacteria dock and enter the membrane.

Stem cells help immature lungs on their way
Children born prematurely often have problems with their lungs. Can stem cells help repair their damaged lungs? Biologist Tim Wolfs is researching it with support from Longfonds (Lung Fund). The lungs of premature children are unfinished. In addition, the lungs often suffer additional damage. This can already happen during pregnancy, for example due to an infection in the amniotic fluid.

Attitude towards science depends on what you think you know, rather than what you actually know
Attitude towards science depends on what you think you know, rather than what you actually know
Survey of over 2,000 adults in the UK identifies potential pitfalls of science communication. Why do people hold highly variable attitudes towards well-evidenced science? For many years researchers focused on what people know about science, thinking that -to know science is to love it-. But do people who think they know science actually know science?
