Researchers decipher how an enzyme modifies the genetic material in the cell nucleus
Inside the cell nucleus, the DNA molecule is found in a densely packed DNA-protein complex known as chromatin. Here the DNA is wrapped around a core of histone proteins and densely packed to form nucleosomes. The structure of the nucleosomes determin.....»»
Researchers detect a new molecule in space
New research from the group of MIT Professor Brett McGuire has revealed the presence of a previously unknown molecule in space. The team's open-access paper, "Rotational Spectrum and First Interstellar Detection of 2-Methoxyethanol Using ALMA Observa.....»»
New small molecule helps scientists study regeneration
Regenerating damaged tissues or organs has been a dream of scientists for decades. Now, researchers at the FMI and Novartis Biomedical Research have discovered a new molecule that activates a protein involved in regeneration. The tool holds promise f.....»»
Springing simulations forward with quantum computing
Though "coupled oscillations" may not sound familiar, they are everywhere in nature. The term "coupled harmonic oscillators" describes interacting systems of masses and springs, but their utility in science and engineering does not end there. They de.....»»
Mangrove blue carbon at higher risk of microplastic pollution
Earth's oceans and coastal ecosystems are a major sink for carbon storage, known as blue carbon. Sequestration of carbon is vitally important in the fight against climate change as it 'locks away' this molecule, alleviating pressure on greenhouse gas.....»»
A hydrocarbon molecule as supplier and energy storage solution for solar energy
Until now, the generation and storage of electricity from solar energy has been dependent on various devices, leading to conversion losses. That may change soon, as chemists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and other resea.....»»

In the field of organic chemistry, scientists are always looking out for new types of reactions to unlock synthesis routes for challenging compounds. Most of the progress that we have witnessed in pharmaceutics and agrochemicals over the past few dec.....»»
Discovery of the first fractal molecule in nature
An international team of researchers led by groups from the Max Planck Institute in Marburg and the Philipps University in Marburg has stumbled upon the first regular molecular fractal in nature. They discovered a microbial enzyme—citrate synthase.....»»
A simple, inexpensive way to make carbon atoms bind together
The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon—a carbon atom bond.....»»
AI improves monsoon rainfall predictions
Every year, the South Asian monsoon season brings heavy rain to over a billion people in the Indian subcontinent between June and September. The rain falls in oscillations: Some weeks see 1 to 4 inches of water, while other weeks are mostly dry. Pred.....»»
How to safely watch a solar eclipse with children
The next solar eclipse will be visible across North America on April 8. Solar eclipses occur when the moon passes between the sun and the Earth, blocking sunlight and casting a shadow on our planet. There will be a 115-mile-wide path stretching from.....»»
Tips to safely watch the total solar eclipse
On April 8, North America will experience a total solar eclipse, stretching across parts of Mexico, the U.S. and Canada, with approximately 31.6 million people living in the path of totality. According to NASA, every contiguous state in the U.S., alo.....»»
