Discovery of the first fractal molecule in nature

‘We stumbled on this structure completely by accident and almost couldn’t believe what we saw when we first took images of it using an electron microscope’

12-Apr-2024 - Snowflakes, fern leaves, romanesco cauliflower heads: many structures in nature have a certain regularity. Their individual parts resemble the shape of the whole structure. Such shapes, which repeat from the largest to the smallest, are called fractals. But regular fractals that match almost ...

Microscopy: Overcoming the traditional resolution limit for the fast co-tracking of molecules

Researchers have developed an innovative method to simultaneously track rapid dynamic processes of multiple molecules at the molecular scale

16-Feb-2024 - Processes within our bodies are characterized by the interplay of various biomolecules such as proteins and DNA. These processes occur on a scale often within a range of just a few nanometers. Consequently, they cannot be observed with fluorescence microscopy, which has a resolution limit of ...

New experiment reveals how ultrafast conversion of urea progresses

Key to the origin of life found

03-Jul-2023 - How did life begin on Earth? Experts have long been fascinated by this question and over the years have come up with a variety of theories. One hypothesis is that the origin of life can be traced back to warm little ponds which are thought to have existed on Earth four billion years ago. The ...

New findings could pave the way to detecting the building blocks of life in our solar system

Detecting biomolecules on ocean moons

07-Dec-2022 - It would be technically possible for future space missions to detect DNA, lipids, and other bacterial components on ocean moons in our solar system – provided that these building blocks of life do exist beyond Earth. This is the conclusion that has now been reached by an international team of ...

A New Tool for Cryo-Electron Microscopy

New method that combines cryo-EM with a method otherwise used in materials research

12-Sep-2022 - Researchers at Forschungszentrum Jülich and Heinrich Heine University Düsseldorf led by Prof. Dr. Carsten Sachse are using cryo-electron microscopy, or cryo-EM for short, to make biomolecules visible at the atomic level. In a paper now published in the journal Nature Methods, they present a new ...
