Rabi oscillations in a stretching molecule
Over eighty years ago, Rabi oscillations were proposed to describe the strong coupling and population transfer in a two-level quantum system exposed to an oscillatory driving field. As compared to atoms, molecules have an extra degree of vibration, w.....»»
China IC designers score points in developing homegrown CPUs
China has witnessed rapid development of homegrown CPU chips in recent years, gradually stretching from single product development to ecosystem deployments looking to break the dominance by Intel and AMD. Apart from the veteran CPU developer Loongson.....»»
Bacteria could help to capture greenhouse gases
Carbon dioxide is an important molecule necessary for life on Earth. Trees need CO2 for photosynthesis, crops produce higher yields in its presence, and some bacteria can transform it into food. The molecule is even an important part of human health,.....»»
Molecule from ancient bacteria-like cells may shed new light on sexual reproduction
A study presents the theory that egg-sperm fusion, a crucial feature of sexual reproduction in plants and animals, may have originated from an ancient form of genetic exchange that involved the fusion of bacteria-like microorganisms called archaea. T.....»»
MIT Scientists Propose "Space Bubbles" to Deflect Solar Radiation, Ease Climate Change
Popular Science reports: A raft of thin-film silicon bubbles deployed from Earth into outer space and stretching to the size of Brazil could potentially block the Sun's solar radiation from further warming Earth, possibly helping to not only stave o.....»»
Cell protection, immunomodulation and virus inhibition by an endogenous substance
The endogenous molecule itaconic acid has antiviral and anti-inflammatory effects, as researchers from TWINCORE have recently shown. In cooperation with scientists from the Helmholtz Centre for Infection Research in Braunschweig and the Helmholtz Ins.....»»
Team discovers signaling molecule that potently stimulates hair growth
University of California, Irvine-led researchers have discovered that a signaling molecule called SCUBE3 potently stimulates hair growth and may offer a therapeutic treatment for androgenetic alopecia, a common form of hair loss in both women and men.....»»
Small molecule transports iron in mice, human cells to treat some forms of anemia
A natural small molecule derived from a cypress tree can transport iron in live mice and human cells lacking the protein that normally does the job, easing a buildup of iron in the liver and restoring hemoglobin and red blood cell production, a new s.....»»
Stretching of the continents drove ancient global warming event, say scientists
Scientists at the University of Southampton have discovered that stretching of the continents is likely to have caused one of the most extreme and abrupt episodes of global warming in Earth history......»»
Scientists engineer quantum processor to emulate a small organic molecule
A team of quantum computer physicists at UNSW Sydney has engineered a quantum processor at the atomic scale to simulate the behavior of a small organic molecule, solving a challenge set some 60 years ago by theoretical physicist Richard Feynman......»»
Researchers uncover molecular basis of antigen processing for cancer target MR1
In a new study published in Nature Chemical Biology, researchers at Children's Hospital of Philadelphia (CHOP) have revealed the molecular mechanics of a cell-surface molecule that is a potential immunotherapy target. Using sophisticated techniques,.....»»
Over 100 Million Americans Urged To Stay Indoors Over Extreme Heat and Humidity
More than 100 million Americans are being warned to stay indoors if possible as high temperatures and humidity settle in over states stretching through parts of the Gulf coast to the Great Lakes and east to the Carolinas. From a report: The National.....»»
Stretching sands as desertification spreads to Europe
Drought and desertification threatens to degrade land in Europe and around the world......»»
Study describes new way of generating insulin-producing cells
Researchers at Karolinska Institutet in Sweden show how a molecule that they have identified stimulates the formation of new insulin-producing cells in zebrafish and mammalian tissue, through a newly described mechanism for regulating protein synthes.....»»
Promising anticancer molecule identified
Researchers at Kanazawa University in collaboration with teams from Toyama Prefectural University and BioSeeds Corporation report in ACS Applied Materials & Interfaces the identification of a molecule with enhanced antiproliferative activity in cance.....»»
Direct transformation of CH3Cl to acetic acid through a carbonylation reaction
Methane, the main component of natural gas, shale gas and flammable ice, is a clean and inexpensive chemical feedstock with abundant reserves. Nevertheless, the high C-H band energy and low polarizability of a methane molecule inhibit the utilization.....»»
The non-coding 7S RNA regulates gene expression in human mitochondria
A new study published in the journal Cell shows that a non-coding RNA molecule regulates mitochondrial gene expression in human cells. The work results from a collaboration between the University of Gothenburg and Karolinska Institutet, both Sweden,.....»»
Metallic five-membered ring pushes the boundaries of aromaticity
Researchers at Chemnitz University of Technology, Humboldt Universität Berlin and Philipps-Universität Marburg succeed in synthesizing a molecule that should not actually exist.....»»
Iron catalyst could make important chemical reactions cheaper and more eco-friendly
A catalyst is a key ingredient for many chemical reactions. It facilitates a molecule to change into another molecule, without being changed itself, meaning it can be used multiple times. However, many catalysts are made of precious metals, making th.....»»
Researchers detect a novel binding mechanism between small and gigantic particles
Researchers at the 5th Physical Institute of the University of Stuttgart have verified a novel binding mechanism forming a molecule between a tiny charged particle and a gigantic (in molecular terms) Rydberg atom. The scientists observed the molecule.....»»
Unlocking the secrets of maple syrup, one molecule at a time
Nature conceals a phenomenal number of molecules as varied as they are imperceptible. The plant kingdom is particularly chemically complex......»»
