How inflammatory signalling molecules contribute to carcinogenesis
Researchers have managed to identify a previously unknown molecular connection between an inflammatory signalling molecule and one of the main oncogenes......»»
Researchers use supercomputer to determine whether "molecules of life" can be formed naturally in right conditions
Basic biology textbooks will tell you that all life on Earth is built from four types of molecules: proteins, carbohydrates, lipids, and nucleic acids. And each group is vital for every living organism......»»
Transcription factor"s key role in grafted cucumbers reveals salt tolerance in crops
Soil salinity, impacting about 1 billion square hectometers worldwide, significantly hinders crop growth. Plants counteract this through signaling pathways involving molecules such as H2O2 and ABA. NAC transcription factors, which are unique to plant.....»»
New research brings order to disordered proteins
Protein molecules lie at the heart of biology. Our typical understanding of proteins states that each type of protein has a specific three-dimensional shape that enables it to perform its function. This dogma is challenged by intrinsically disordered.....»»
A new wavelength of scientific exploration with single-photon detectors
From the minuscule bindings of molecules to the far reaches of space, we're exploring the universe around us by catching sight of the smallest particles of light......»»
Physicists develop novel concept for detecting chiral molecules
In contrast to conventional mirrors, light can be reflected on surfaces known as metasurfaces without changing its polarization. This phenomenon has now been proven by physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the Ma.....»»
New study reports that Greenland is a methane sink rather than a source
Researchers at the University of Copenhagen have concluded that the methane uptake in dry landscapes exceeds methane emissions from wet areas across the ice-free part of Greenland. The results of the new study contribute important knowledge to climat.....»»
Chemical biology: A novel approach to synthesize dibenzothiophene s-oxides
Organic compounds in the field of chemistry range from simple hydrocarbons to complex molecules, with diverse functional groups added to the main carbon backbone. These functional groups impart distinct chemical properties to the compounds and partic.....»»
Understanding nutrient cycling between algae and bacteria could lead to increased biofuel production
The interactions between algae and bacteria are essential to the primary productivity of Earth's oceans and surface waters. Bacteria can increase the productivity of algae by producing key factors, such as vitamins, iron-chelating molecules, and grow.....»»
Enzyme for biocatalysis uses solvent as a substrate
A large number of applications in the chemical industry rely on the molecules NADH or NADPH as fuel. A team led by Professor Dirk Tischler, head of the Microbial Biotechnology working group at Ruhr University Bochum, used a biocatalyst to study their.....»»
Ancient "relaxant-inflammatory" mechanism gets sponges moving
Did you know that sponges can move? While not exactly the champions of underwater acrobatics, sponges exhibit coordinated movements—despite not having muscles or neurons......»»
New design improves water decontamination via plasma jet
Plasma is an ionized gas—that is, a gas containing electrons, ions, atoms, molecules, radicals, and photons. It is often called the fourth state of matter, and surprisingly, it permeates everything. Plasmas, which are artificially generated by tran.....»»
Research unveils how plants control the production of reactive oxygen species
Reactive oxygen species (ROS) are highly reactive molecules containing oxygen. These compounds, which are normal byproducts of biological processes in all living organisms such as aerobic respiration as well as photosynthesis, are highly toxic. In mo.....»»
Study offers new insights into understanding and controlling tunneling dynamics in complex molecules
Tunneling is one of most fundamental processes in quantum mechanics, where the wave packet could traverse a classically insurmountable energy barrier with a certain probability......»»
Cells" electric fields keep nanoparticles at bay, scientists confirm
The humble membranes that enclose our cells have a surprising superpower: They can push away nano-sized molecules that happen to approach them. A team including scientists at the National Institute of Standards and Technology (NIST) has figured out w.....»»
Innovative membrane platform enables analysis "down to a handful of gas atoms"
Northwestern University researchers have developed a novel method to host gas molecules as they are being analyzed in real time, using honeycomb structures found in nature as inspiration for an ultra-thin ceramic membrane they incorporated to encase.....»»
"Magic trap" preserves quantum coherence in ultracold molecules longer than expected
Quantum technologies bring the promise of faster computing, enhanced drug development and new sensing applications. However, quantum behaviors are difficult to study experimentally since most systems can only sustain quantum effects for a short time......»»
Researchers develop a low-cost catalyst for green hydrogen production
Electrolysis is a process that uses electricity to create hydrogen and oxygen molecules from water. The use of proton exchange membrane (PEM) and renewable energy for water electrolysis is widely regarded as a sustainable method for hydrogen producti.....»»
Researchers address formulation, manufacturing challenges in obesity, diabetes drugs
Medications such as Ozempic and Mounjaro are composed of molecules called acylated peptides that are designed to circulate in the body and regulate insulin production. This enables adults with type 2 diabetes to take a weekly injection instead of mon.....»»
Elucidating the biosynthetic mechanism for protoberberine alkaloids from Coptis chinensis
Protoberberine alkaloids are a group of tetracyclic isoquinoline compounds known for their well-established antimicrobial and anti-inflammatory properties. Although protoberberine alkaloids are broadly found in various plant families such as Ranuncul.....»»
Shape-shifting protein study could advance new drug development
Proteins do the heavy lifting of performing biochemical functions in our bodies by binding to metabolites or other proteins to complete tasks. To do this successfully, protein molecules often shape-shift to allow specific binding interactions that ar.....»»
