Researchers extend the life of a dipolar molecule
In 2018, Kang-Kuen Ni and her lab earned the cover of Science with an impressive feat: They took two individual atoms, a sodium and a cesium, and forged them into a single dipolar molecule, sodium cesium......»»
Small-molecule therapeutics: Big data dreams for tiny technologies
Small-molecule therapeutics treat a wide variety of diseases, but their effectiveness is often diminished because of their pharmacokinetics—what the body does to a drug. After administration, the body dictates how much of the drug is absorbed, whic.....»»
Kirigami-style fabrication may enable new 3D nanostructures
A new technique that mimics the ancient Japanese art of kirigami may offer an easier way to fabricate complex 3D nanostructures for use in electronics, manufacturing and health care......»»
Molecule attacks coronavirus in a novel way
Scientists at the University of Bonn and the caesar research center have isolated a molecule that might open new avenues in the fight against SARS coronavirus 2. The active ingredient binds to the spike protein that the virus uses to dock to the cell.....»»
Scientist discovers a new type of "bi-molecule" with applications for quantum sensors
Dr. Rosario González-Férez, a researcher at the Department of Atomic, Molecular and Nuclear Physics and the Carlos I Institute of Theoretical and Computational Physics of the University of Granada, has published an article titled "Ultralong-Range R.....»»
First 3D images of a giant molecule
Capturing the structure of large molecular complexes with variable shape is an extremely difficult task. Scientists from Würzburg and Montpellier now have been able to do it—thanks to a new approach regarding an important protein machine......»»
Cold molecular clouds as cosmic ray detectors
The ionization of the neutral gas in an interstellar molecular cloud plays a key role in the cloud's evolution, helping to regulate the heating and cooling processes, the chemistry and molecule formation, and coupling the gas to magnetic fields. Usua.....»»
A single-molecule electrical approach for amino acid detection and chirality recognition
Analytical chemistry aims to efficiently discriminate between two amino acids. In a new report in Science Advances, Zihao Liu and a research team in Chemistry, Physics, and Materials Science in China and Japan, used a single-molecule electrical metho.....»»
Researchers identify non-coding RNA molecule in trypanosome parasites
Trypanosomatids are single-cell parasites that cause major diseases, such as sleeping sickness and Rose of Jericho, which affect millions of people. Trypanosoma parasites are transmitted to mammals by the blood-sucking tsetse fly. The parasite's stop.....»»
Determining the structure of a molecule with laser-induced electron diffraction
Light microscopes have revolutionized our understanding of the microcosmos, but their resolution is limited to about 100 nanometers. To see how molecules bond, break, or change their structure, we need at least 1000 times better resolution......»»
Study reveals details of immune defense guidance system
At the beginning of an immune response, a molecule known to mobilize immune cells into the bloodstream, where they home in on infection sites, rapidly shifts position, a new study shows. Researchers say this indirectly amplifies the attack on foreign.....»»
Researchers can store the Declaration of Independence in a single molecule
Just how much space would you need to store all of the world's data? A building? A block? A city?.....»»
Common bacteria modified to make designer sugar-based drug
Envisioning an animal-free drug supply, scientists have reprogrammed a common bacterium to make a designer polysaccharide molecule used in pharmaceuticals and nutraceuticals......»»
Detective work inside plant cells finds a key piece of the C4 photosynthesis puzzle
An impressive body of evidence published this week reveals the answer to a mystery that has puzzled plant scientists for more than 30 years: the role of the molecule suberin in the leaves of some of our most productive crops. This discovery could be.....»»
Common bacteria modified to make designer sugar-based drug
Envisioning an animal-free drug supply, scientists have—for the first time—reprogrammed a common bacterium to make a designer polysaccharide molecule used in pharmaceuticals and nutraceuticals. Published today in Nature Communications, the resear.....»»
Biobattery-powered microneedle patch can deliver drugs and procure testing samples
A pain-free, organic and biodegradable drug delivery patch may be on the horizon for home health care patients soon. Researchers have developed a biobattery-powered device capable of both delivering large molecule pharmaceuticals across the skin barr.....»»
Researchers probe the "full" thermoelectric properties of a single molecule
One of the dreams of physicists today is being able to harvest electricity back from dissipated heat. The key to this probably resides in circuits that contain single molecules. Instead of being limited to classical conductance, the thermopower can b.....»»
"Walking" molecule superstructures could help create neurons for regenerative medicine
By discovering a new printable biomaterial that can mimic properties of brain tissue, researchers are now closer to developing a platform capable of conditions using regenerative medicine......»»
New insights on how inflammatory molecule contributes to skin and pancreatic cancers
An immune molecule called interleukin-33 can act within a cell's nucleus to stimulate abnormal growth and division, ultimately resulting in cancer. Targeting interleukin-33 in the nucleus may help prevent certain cancers......»»
Mitochondrial function can play significant part in serious disease
Disorders of the cells' energy supply can cause a number of serious diseases, but also seem to be connected to ageing. More research is needed on mitochondrial function to find future treatments. A new study shows how an important molecule inside the.....»»
