Researchers have incorporated molecules of porphyrin CO2 catalysts into the sponge-like crystals of covalent organic frameworks (COFs) to create a molecular system that not only absorbs carbon dioxide, but also selectively reduces it to CO, a primary building block for a wide range of chemical products.
Researchers have identified in an animal model the molecular mechanisms behind resilience to noise-induced tinnitus and a possible drug therapy that could reduce susceptibility to this chronic and sometimes debilitating condition.
Stimulated Radiative Molecular Association in the Early Solar System. II. Orbital Radii of the Planets and Other Satellites of the SunAuthor:LombardiAbstract:In a previous investigation, the orbital radii of regular satellites of Uranus,...Show More Summary
To help molecular pathologists, laboratory directors, bioinformaticians and oncologists identify key mutations that drive tumor growth in tissues obtained during cancer clinical studies, researchers have designed an online database called the Cancer Driver Log, or CanDL.
Depression and anxiety disorders are the most common psychiatric disorders. Over the last few years, molecular brain imaging using Positron Emission Tomography (PET) has helped us to identify important mechanisms involved in the development and treatment of these disorders, particularly those associated with the serotonin neurotransmitter system.
Lecithin plays a vital role in the production of chocolate and many other foods. It's never been clear how this ingredient works on a molecular level, and confectioners have relied on observational methods -- essentially trial and error -- to perfect their recipes. Show More Summary
Lecithin is an ingredient that you've probably never heard of, but one that plays a vital role in the production of chocolate and many other foods. It's never been clear how this ingredient works on a molecular level, and confectioners have relied on observational methods - essentially trial and error - to perfect their recipes. read more
For a long time, one of the key defining factors of glasses has been their molecular randomness; but when a team at the University of Chicago, led by Professor Juan de Pablo, were analyzing a glass that they had grown in their lab they saw unusual peaks
Researchers using a bioinorganic hybrid approach to artificial photosynthesis have combined semiconducting nanowires with select microbes to create a system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane, the primary constituent of natural gas.
Thanks in part to screening technologies like colonoscopy; colon cancer is often detected in its earliest stages. Researchers have now found a way to screen blood samples for molecular traces that indicate the presence of precancerous polyps in the colon, a key warning sign for colon cancer.
The molecular switches regulating human cell growth do a great job of replacing cells that die during the course of a lifetime. But when they misfire, life-threatening cancers can occur. Research has now revealed a new electrical mechanism that can control these switches.
Toronto researchers have discovered that a single molecular event in our cells could hold the key to how we evolved to become the smartest animal on the planet. Benjamin Blencowe, a professor in the University of Toronto's Donnelly Centre...Show More Summary
A molecular approach has been used to identify the protein responsible for germination of Striga seeds through visualization by green fluorescence. Striga, a parasitic plant known as witchweed has seriously affected millions of hectares of crop fields in Africa that poses a major threat to food security. Show More Summary
University of Chicago scientists accidentally created an entirely new type of glass – one with unusual peaks that indicate a molecular order in a material previously thought to be entirely amorphous and random.
New light has been shed on how the variations in our molecular make-up, such as gene expression, are controlled within our DNA. The research leads to a greater understanding of how certain genetic variants can ‘switch’ on or off theShow More Summary
When they think about how cells put together the molecules that make life work, biologists have tended to think of assembly lines: Add A to B, tack on C, and so on. But the reality might be more like a molecular version of a 3-D printer, where a single mechanism assembles the molecule in one go.
An Atlanta-based biotech plans to raise $10.5 million, according to a Securities & Exchange Commission filing. Phigenix Inc. uses molecular therapeutics that target the immune system to prevent and fight prostate cancer. The companyShow More Summary
Bacteria exhibit extreme adaptability, which makes them capable of surviving in the most inhospitable conditions. New research results produced by Danish and British researchers now reveal the molecular details behind one of the secret weapons used by bacteria in their battle to survive under very nutrient-poor and even toxic conditions.
Researchers have identified within neurons a series of molecular interactions -- known as a pathway -- that can dampen the production of the Alzheimer's protein amyloid-?. These results suggest a new route in the search for therapies for this degenerative disease.
There's going to be a point where Moore's law stops -- because the things we build can only get so small before quantum physics starts to really mess with how circuits behave. Still, researchers keep pushing technology to make smaller and smaller devices. Show More Summary
