"ZIP" codes tell RNA molecules how to get to their designated locations
They say that life comes without an instruction manual, but that's not entirely true. Each cell in our bodies lives according to instructions issued by its DNA in the form of RNA molecules. RNA was recently thrust into the limelight as the basis of i.....»»
Researchers develop molecules for a new class of antibiotics that can overcome drug resistant bacteria
About a decade ago, researchers in UC Santa Barbara chemistry professor Guillermo Bazan's lab began to observe a recurring challenge in their research: Some of the compounds they were developing to harness energy from bacteria were instead killing th.....»»
Scientists track world"s largest turtles to previously unknown foraging locations
Leatherback sea turtles, the largest of all living turtles, undertake extensive migrations that can span multiple years. They travel from subtropical and tropical nesting locations to temperate foraging areas. Despite decade-long tracking efforts, th.....»»
New synthesis method uses light reaction on a water surface
By forming chemical bonds between atoms, complex molecules such as those needed for medicines, crop protection products, or high-performance materials are prepared using synthetic chemistry. Such synthesis reactions typically require organic solvents.....»»
Programming cells to organize their molecules may open the door to new treatments
Researchers can engineer cells to express new genes and produce specific proteins, giving the cells new parts to work with. But, it's much harder to provide cells with instructions on how to organize and use those new parts. Now, new tools from Unive.....»»
Important molecular pathway for control of aging discovered
One of the ways cells in different kinds of tissue communicate is by exchanging RNA molecules. In experiments with roundworms of the species Caenorhabditis elegans, researchers at the State University of Campinas (UNICAMP) in Brazil found that when t.....»»
Astronomers investigate the atmosphere of a nearby cold brown dwarf
Using the James Webb Space Telescope (JWST), astronomers have observed a nearby cold brown dwarf designated WISEPA J182831.08+265037.8 (or WISE 1828 for short). The observations delivered important insights into the composition of the object's atmosp.....»»
SPNS2 found to be directly exporting S1P for signaling, can be inhibited
When an enemy invades, defenders are ferried to the site to neutralize the marauders. In the human body, a protein carrier called SPNS2 transports S1P molecules from endothelial cells to rally immune cell response in infected organs and tissues......»»
Discovery of new plant protein fold may be seed for anti-cancer drugs
University of Michigan researchers are celebrating their discovery of a new plant biochemistry and its unusual ability to form cyclic peptides—molecules that hold promise in pharmaceuticals as they can bind to challenging drug targets......»»
Viewpoint: Wildlife selfies harm animals, even when scientists share images with warnings in the captions
One of the biggest privileges of being a primatologist is spending time in remote locations with monkeys and apes, living near these animals in their habitats and experiencing their daily lives. As a 21st-century human, I have an immediate impulse to.....»»
J0526+5934 is an ultra-short period double white dwarf, observations show
Using ground-based telescopes, an international team of astronomers has observed a binary system containing at least one white dwarf, designated J0526+5934. The observational campaign has revealed that the binary is composed of two white dwarfs on an.....»»
Microscopy method overcomes the traditional resolution limit for the fast co-tracking of molecules
Researchers at Ludwig Maximilian University (LMU) have developed an innovative method to simultaneously track rapid dynamic processes of multiple molecules at the molecular scale......»»
How NASA uses simple technology to track lunar missions
NASA is using a simple but effective technology called Laser Retroreflective Arrays (LRAs) to determine the locations of lunar landers more accurately. They will be attached to most of the landers from United States companies as part of NASA's Commer.....»»
Exploring the effect of ring closing on fluorescence of supramolecular polymers
In supramolecular chemistry, the self-assembly state of molecules plays a significant role in determining their tangible properties. Controlling the self-assembled state has garnered significant attention as it can be exploited to design materials wi.....»»
The San people of southern Africa: Where ethics codes for researching indigenous people could fail them
There is a long and often complicated history of researchers studying Indigenous people. In 1999, the education scholar Linda Tuhiwai-Smith, in her book "Decolonizing Methodologies: Research and Indigenous Peoples, "emphasized the colonial character.....»»
Scientists identify water molecules on asteroids for the first time
Using data from the retired Stratospheric Observatory for Infrared Astronomy (SOFIA)—a joint project of NASA and the German Space Agency at DLR—Southwest Research Institute scientists have discovered, for the first time, water molecules on the su.....»»
Helium droplets capture double water structure
An elusive structure involving two water molecules, which had been predicted but never observed, has been isolated by RIKEN chemists. This finding could have implications for a wide range of fields ranging from astrochemistry to corrosion of metals......»»
Understanding the chemical communication between cells
Like the people they make up, cells communicate by bumping into one another and exchanging handshakes. Unlike people, cells perform these handshakes using the diverse range of sugar molecules coating their surface like trees covering a landscape. Han.....»»
Researchers discover cosmic dust storms from Type 1a supernova
Cosmic dust—like dust on Earth—comprises groupings of molecules that have condensed and stuck together in a grain. But the exact nature of dust creation in the universe has long been a mystery. Now, however, an international team of astronomers f.....»»
Probing proton pumping: New findings on protein folding in bacteriorhodopsin
When it comes to drug development, membrane proteins play a crucial role, with about 50% of drugs targeting these molecules. Understanding the function of these membrane proteins, which connect to the membranes of cells, is important for designing th.....»»
