Simple Chemical Reaction may Help Early Disease Diagnosis
...easily identifiable isotope, in this case a carbon atom
that is heavier than the standard carbon atom. Because we can easily detect this isotope, it causes these tagged metabolites to effectively pop out against the background of all of the others, Raftery said. The findings of the study were published ...
Researchers Devise New Compound to Treat Fungal Infections
...aid. The mechanism crucially depended on a boron atom
that is part of AN2690, which is needed to link the compound to the tRNA. "We are now working towards finding related antibacterial compounds that could help counter the problem of antibiotic resistance," Cusack said. The findings of the study we...
Scientists in Britain Create Artificial Blood
... is made up of plastic molecules that have an iron atom
at their core, like haemoglobin, that can carry oxygen through the body. The researchers say they were looking for extra funding to develop a final prototype that would be suitable for biological testing, according to BBC News. "We are very excit...
Circadian Clocks Triggered Chemical Reactions may Be Behind Jet Lag
...ction on and off. When they substituted a single atom
(sulphur for oxygen) on the surface of the vivid protein, the chain of events shut down, preventing the structural changes on the protein's surface, as a result of which, the regulation of carotenoid production was disrupted. "We can now show that...
Elusive Step In DNA Mutation Uncovered By Researchers
...etely understood. A free radical, a stable neutral atom

of the guanine to bond with a water molecule. In a concerted motion, the oxygen atom
of the water mo...

Scientists Consider About New Technology Called Nanotechnology
...the matter in the universe is made up of atoms. An atom
so small than even what you can imagine, is arranged in different forms to account for the variability in the various forms of matter. For example, charcoal and diamond are made up of atoms of the same element carbon. It is the spatial arrangement of...
Human Diseases May Have Clue In Human-Chimp Genome Difference
... human brain diseases; the second, a single oxygen atom
difference that makes humans and chimpanzees resistant to each other’s malarial parasites. This research provides examples of how studying the evolution of humans and apes from a common ancestor may yield clues to explaining human and chimpanzee dis...
The Benefits of Strontium in the treatment for Osteoporosis Questioned
...ate, bone tissue will contain around one strontium atom
for every 100 calcium atoms. No human studies have yet reported how quickly bone strontium is washed out once treatment is stopped. An impressive increase in bone mineral density occurred in the spine (14.4%) and hip (8.3%).7. However, some caution ...
Stay young the Chinese way
....// Oxidation is a chemical reaction in which an atom
loses its electron, and this change, if it happens in the human body, results in aging of human cells and tissue. The world medical community found in the 1990s that a kind of oxygenic molecule, scientifically called free radicals left by metabolic p...
