Reconstructing ancient bacterial genomes can revive previously unknown molecules, a potential source for new antibiotics
Microorganisms—in particular bacteria—are skillful chemists that can produce an impressive diversity of chemical compounds known as natural products. These metabolites provide the microbes major evolutionary advantages, such as allowing them to i.....»»
Scientists capture elusive chemical reaction using enhanced X-ray method
Researchers at SLAC National Accelerator Laboratory captured one of the fastest movements of a molecule called ferricyanide for the first time by combining two ultrafast X-ray spectroscopy techniques. They think their approach could help map more com.....»»
New imaging approach visualizes how applying force to proteins alters complex formations
Most researchers today understand biology through the principles of biochemistry. Cells communicate and activate processes via chemical signals, and traditional medicine has long focused on how to treat disease by modifying those signals......»»
Researchers discover an alternative to ATP for string-shaped motors in cells
Cells have a fascinating feature to neatly organize their interior by using tiny protein machines called molecular motors that generate directed movements. Most of them use a common type of fuel, a kind of chemical energy, called ATP to operate......»»
Scientists detect gases from fractured rock
Geoscientists have detected specific gases being released from fractured rocks in real time after a series of small chemical explosions set underground......»»
Chemical signal protects migratory locusts from cannibalism
Huge swarms of migratory locusts take on the proportions of natural disasters and threaten the food supply of millions of people, especially in Africa and Asia. As the eighth of the ten biblical plagues, the Book of Moses in the Old Testament already.....»»
Chemists find that metal atoms play key role in fine organic synthesis
A small team of chemists at the Russian Academy of Sciences, has found that metal atoms, not nanoparticles, play the key role in catalysts used in fine organic synthesis. In the study, reported in the Journal of the American Chemical Society, the gro.....»»

In a result decades in the making, Los Alamos scientists have achieved light amplification with electrically driven devices based on solution-cast semiconductor nanocrystals—tiny specs of semiconductor matter made via chemical synthesis and often c.....»»
Astronomers find distant gas clouds with leftovers of the first stars
Using ESO's Very Large Telescope (VLT), researchers have found, for the first time, the fingerprints left by the explosion of the first stars in the universe. They detected three distant gas clouds whose chemical composition matches what we expect fr.....»»
Solving the mystery of protein surface interactions with geometric fingerprints
Researchers from the Swiss Institute of Bioinformatics, Lausanne in Switzerland, used a geometric deep-learning tool that generates "fingerprints" of protein surfaces to describe geometric and chemical features critical to protein–protein interacti.....»»
How a single enzyme unleashes a complex DNA repair process
Our DNA is constantly exposed to damaging factors that can lead to aging and age-related diseases such as cancer. PARP1 is an important enzyme that facilitates the response to DNA damage by attaching chemical groups called ADP-ribose to proteins. Pub.....»»
Discovering hidden order in disordered crystals
Researchers at Tokyo Tech have discovered hidden chemical order of the Mo and Nb atoms in disordered Ba7Nb4MoO20, by combining state-of-the-art techniques, including resonant X-ray diffraction and solid-state nuclear magnetic resonance. This study pr.....»»
Advanced X-ray technique unveils fast solid-gas chemical reaction pathways
For the rational design of new material compounds, it is important to understand the mechanisms underlying their synthesis. Analytical techniques such as nuclear magnetic resonance and spectroscopy are usually employed to study such mechanisms in mol.....»»
Microbial necromass carbon causes dramatic carbon loss in permafrost thaw slump of Tibetan Plateau
Permafrost in the Tibetan Plateau contains a large amount of soil organic carbon (SOC). Climate change leads to rapid permafrost degradation and thermal collapse, which can change the microgeomorphology and soil physical and chemical properties......»»
Earliest animal likely used chemical signaling to evolve into multicellular organism
The earliest animal likely used chemical signaling to evolve from a single cell to a multicellular organism, according to a study led by an Indiana University Bloomington scientist. The findings provide new information about how one of the biggest tr.....»»
