A nanoemulsion containing particles of curcumin, which is known to have anti-inflammatory and antioxidant properties, has been found capable of modulating the gut microbiota of mice with intestinal inflammation in experiments conducted by researchers.....»»
Ultraviolet spectroscopy: A leap in precision and accuracy at extremely low light levels
Ultraviolet spectroscopy plays a critical role in the study of electronic transitions in atoms and rovibronic transitions in molecules. These studies are essential for tests of fundamental physics, quantum-electrodynamics theory, determination of fun.....»»
Scientists use a new type of nanoparticle that can both deliver vaccines and act as an adjuvant
Many vaccines, including vaccines for hepatitis B and whooping cough, consist of fragments of viral or bacterial proteins. These vaccines often include other molecules called adjuvants, which help to boost the immune system's response to the protein......»»
Chemists break barriers and open up super-resolution molecule mass analysis
A team of chemists led by Prof. Albert Heck puts a new spin on analyzing and understanding molecules. By ingeniously improving current measuring equipment, the team was able to trap and observe individual molecules for a much longer period—up to 25.....»»

Research team develops protein-based microcapsule for point-of-care diagnostics
Aptamers, the nucleic acid-based biosensors with the ability to bind specific proteins or small molecules, offer a way to identify target molecules without the complexity of analytical apparatuses. While being increasingly used in diagnostic applicat.....»»
Novel RNA- or DNA-based substances can protect plants from viruses, scientists show
Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study by the Martin Luther University Halle-Wittenberg (MLU) published in the International Journal of Molecular Sciences......»»
Microbial viruses act as secret drivers of climate change, new study finds
In a new study, scientists have discovered that viruses that infect microbes contribute to climate change by playing a key role in cycling methane, a potent greenhouse gas, through the environment......»»
How molecular "handedness" emerged in early biology
Molecules often have a structural asymmetry called chirality, which means they can appear in alternative, mirror-image versions akin to the left and right versions of human hands. One of the great mysteries about the origins of life on Earth is that.....»»
Light stimulates a new twist for synthetic chemistry
Molecules that are induced by light to rotate bulky groups around central bonds could be developed into photo-activated bioactive systems, molecular switches, and more......»»
Trapping and excitation of the simplest molecule: Precise measurement matches theoretical predictions
The simplest possible molecule H2+ was one of the very first molecules to form in the cosmos. This makes it significant for astrophysics, but also an important object of research for fundamental physics. However, it is difficult to study in experimen.....»»
New molecules, inspired by space shuttles, advance lipid nanoparticle delivery for weight control
Inspired by the design of space shuttles, Penn Engineering researchers have invented a new way to synthesize a key component of lipid nanoparticles (LNPs), the revolutionary delivery vehicle for mRNA treatments including the Pfizer-BioNTech and Moder.....»»
Researchers discover cause of initial spike in immune response when pathogens attack plants
When pathogens attack plants, the plant cells almost immediately react. The plant's cells begin to produce different kinds of small molecules called secondary messengers. These messengers travel throughout the cell membrane to begin the process of ac.....»»
