Volcanic eruptions trigger ice formation in clouds

Volcanic eruptions trigger ice formation in clouds

When a volcano erupts, it can spew ash high into the atmosphere—inserting aerosols right where clouds typically form. How exactly these aerosols impact cloud formation has long been a mystery to atmospheric scientists.

How Hibiscus flowers lost their bullseyes

How Hibiscus flowers lost their bullseyes

New research reveals how repeated genetic changes in Hibiscus flowers have led to the loss of visually striking bullseye patterns despite their advantage in attracting pollinators like bumblebees.

Structure of liquid carbon measured for the first time

Structure of liquid carbon measured for the first time

With the declared aim of measuring matter under extreme pressure, an international research collaboration headed by the University of Rostock and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) used the high-performance laser DIPOLE 100-X at the European XFEL for the first time in 2023. With spectacular results: In this initial experiment they managed to study liquid carbon—an unprecedented achievement as the researchers report in the journal Nature.

Molecular dynamics simulations show how potassium passes through an ion channel at atomic resolution

Molecular dynamics simulations show how potassium passes through an ion channel at atomic resolution

They are literally channels for communication: Pore-forming proteins in living cells, termed ion channels, are embedded in the outer membrane of almost all cell types and play a crucial role in the body's various communication systems. Blood, immune, and liver cells communicate via these channels. Nerve cells use them to transmit electrical signals to other cells.

Inorganic polycations induce widening of infrared transparency spectrum

Inorganic polycations induce widening of infrared transparency spectrum

As core components for generating coherent tunable radiation sources in all-solid-state lasers, second-order nonlinear optical (NLO) crystals have demonstrated significant technical advantages in many fields. Metal chalcogenides with tetrahedral cluster (Tn) as the structural unit are regarded as candidate systems for NLO materials of the mid- and far-infrared bands due to their potential strong second-harmonic-generation (SHG) response and wide infrared transmission range.

Stress-induced changes in generations of cancer cells tracked live under the microscope

Stress-induced changes in generations of cancer cells tracked live under the microscope

Cells are the smallest units of life. But even within the same tissue or organ, they are not all identical. New variations arise continuously during cell proliferation. While genetic mutations alter the DNA sequence, epigenetic changes influence gene activity.

Nanomaterial achieves dual functionality—high-performance energy storage and efficient pollutant degradation

Nanomaterial achieves dual functionality—high-performance energy storage and efficient pollutant degradation

Researchers from Shinshu University developed a low-cost nanocomposite by embedding bimetallic and trimetallic molybdates into nitrogen-, boron-, and fluorine-doped hollow carbon nanofibers. This material demonstrated excellent electrochemical performance for supercapacitors, with high capacitance and long-term stability, as well as strong catalytic efficiency in degrading 4-nitrophenol, a common industrial pollutant.

Computational tool predicts stable metal-organic frameworks for new energy economy

Computational tool predicts stable metal-organic frameworks for new energy economy

The clean energy transition requires new means to transport energy that are less reliant on burning fossil fuels. This requires new materials to catalyze reactions to store and extract energy from chemical energy carriers without combustion.
