Exploring molecular boundaries in DNA
It's important to be well organized. And this is especially true for the genome—the entirety of an organism's genetic information, also known as DNA. The genomic DNA is several meters long but has to fit inside the cell's nucleus, which has a diame.....»»
Exploring light neutron-rich nuclei: First observation of oxygen-28
The study of physical systems under extreme conditions offers valuable insights into their organization and structure. In nuclear physics, neutron-rich isotopes, especially the light ones with neutron-to-proton ratio significantly different from that.....»»

Research explores first defense against devastating ToCSV tomato virus at a molecular genetics level
How tomato plants defend themselves against a devastating 'young' Southern African virus has now been investigated at a molecular genetics level for the first time by researchers at the University of Johannesburg (UJ)......»»
New experimental research measures the speed of molecular charge migration for the first time
To discover how light interacts with molecules, the first step is to follow electron dynamics, which evolve at the attosecond timescale. The dynamics of this first step have been called charge migration (CM). CM plays a fundamental role in chemical r.....»»
Indian rover begins exploring Moon"s south pole
India began exploring the Moon's surface with a rover on Thursday, a day after it became the first nation to land a craft near the largely unexplored lunar south pole......»»
Learning from viruses: Molecular fibers can help to introduce genetic material into cells
Pathogenic viruses that enter the human body can dock onto cells with their tentacle-like extensions, whereupon the cell takes up the viruses. This process, which is already known and occurs in diseases such as HIV, can also be used for therapeutic a.....»»
Deciphering the molecular dynamics of complex proteins
Which structures do complex proteins adopt in solution? Konstanz biophysicists answer this question using the example of ubiquitin dimers as well as a new combination of high-resolution NMR spectroscopy and sophisticated computer simulations......»»
Serum amyloid A: Exploring links between the beneficial and pathologic actions of an enigmatic protein
Serum amyloid A (SAA) is a family of ancient proteins that can be traced from present-day humans back half a billion years to sea cucumbers and oysters. A new study by researchers from the Boston University Chobanian & Avedisian School of Medicine ex.....»»
Advancements in sustainable chitosan-based nanocomposites for wound dressings
Deepak Verma from Chulalongkorn University and his international team of researchers are exploring ways to enhance chitosan using techniques like adding photosensitizers, dendrimers, and chemical modifications. They also surveyed the use of chitosan.....»»
Stabilizing precipitate growth at grain boundaries in alloys
Materials are often considered to be one phase, but many engineering materials contain two or more phases, improving their properties and performance. These two-phase materials have inclusions, called precipitates, embedded in the microstructure......»»
Researchers discover mechanism by which cancer cells survive replication stress
Researchers from Karolinska Institutet have discovered a new molecular mechanism by which cancer cells safeguard themselves from oncogene-induced replication stress and propose a strategy to deactivate this protective mechanism. The study is publishe.....»»
Sugars affect brain "plasticity," helping with learning, memory, recovery
Can you recognize someone you haven't seen in years, but forget what you had for breakfast yesterday? Our brains constantly rearrange their circuitry to remember familiar faces or learn new skills, but the molecular basis of this process isn't well u.....»»
Decoding how molecules "talk" to each other to develop new nanotechnologies
Two molecular languages at the origin of life have been successfully recreated and mathematically validated, thanks to pioneering work by Canadian scientists at Université de Montréal......»»
Exploring advanced magnesium-based hydrogen storage materials and their applications
As an energy carrier, hydrogen holds the prominent advantages of high gravimetric energy density, high abundance, and zero emissions, yet its effective storage and transportation remain a bottleneck problem for the widespread applications of hydrogen.....»»
Uncovering the local atomic structure of zeolite using optimum bright-field scanning transmission electron microscopy
Zeolites have unique porous atomic structures and are useful as catalysts, ion exchangers and molecular sieves. It is difficult to directly observe the local atomic structures of the material via electron microscopy due to low electron irradiation re.....»»
Off Alaska coast, research crew peers down, down, down to map deep and remote ocean
For the team aboard the Okeanos Explorer off the coast of Alaska, exploring the mounds and craters of the sea floor along the Aleutian Islands is a chance to surface new knowledge about life in some of the world's deepest and most remote waters......»»
Study identifies characteristics specific to human brains
Researchers led by a team at UT Southwestern Medical Center have identified cellular and molecular features of the brain that set modern humans apart from their closest primate relatives and ancient human ancestors. The findings, published in Nature,.....»»
Bringing ultrafast physics to structural biology reveals the dance of molecular "coherence" in unprecedented clarity
