Read moreSpace observatory’s detector technology goes into single-molecule imaging
Since 1999, Yoshiyuki Takizawa has been working on the Extreme Universe Space Observatory (EUSO), an international project to develop a super wide-field telescope capable of observing large volumes of...
Physics and Astronomy | Read moreRing Closure as Warning
Soman, Tabun, and Sarin (which has already been used in terrorist attacks) are chemical weapons that attack the nervous system. When inhaled, these extremely toxic organophosphates can lead to death w...
Life Sciences | Read morePitt researchers harness carbon nanomaterials for drug delivery systems, oxygen sensors
Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent...
Materials Sciences | Read moreUltrasensitive detector promises improved treatment of viral respiratory infections
Writing in The Analyst – a journal published by the Royal Society of Chemistry – the developers report that their technique, which uses DNA hairpins attached to gold filaments, can detect the presence...
Health and Medicine | Read moreExpression of Infrared Fluorescence Engineered in Mammals
Researchers at the University of California, San Diego – led by 2008 Nobel-Prize winner Roger Tsien, PhD – have shown that bacterial proteins called phytochromes can be engineered into infrared-fluore...
Life Sciences | Read moreNew light shed on marine luminescence
The phenomenon of light emission by living organisms, bioluminescence, is quite common, especially in marine species. It is known that light is generated by chemical reactions in which oxygen molecule...
Life Sciences | Read moreA Better Mesh: Researchers ‘Tighten’ Body's Protective Coating
A net with large holes won’t catch small fish. Likewise, the microscopic fibers in the protective mucus coatings of the eyes, lungs, stomach or reproductive system naturally bundle together and allow ...
Life Sciences | Read moreBeaming New Light on Life: Silver Nanoparticle Microscopy
The method also might be used for detecting fatigue in materials such as carbon-fiber plastics used to build the latest generation of aircraft fuselages, tails and wings, says John Lupton, an associat...
Physics and Astronomy | Read moreTiny capsules deliver
"People probably fear the effects of some treatments more than they fear the disease they treat," says Huda A. Jerri, graduate student, chemical engineering. "The drugs are poison. Trea...
Life Sciences | Read moreBetween dormancy and self-renewal: Mainz mouse model shows blood stem cells in action
"This mouse was created from a single embryonic stem cell. We are able to observe its blood stem cells in detail and see when they divide, i.e., become active, and when they are dormant," sa...
Life Sciences | Read moreFluorescent Grooves
In order to arrest a culprit, police look for fingerprints at the scene of the crime. Magnetic powder is applied to the surfaces of objects with a magnetic brush to make these latent fingerpri...
Life Sciences | Read moreNovel technique for fluorescence tomography of tumors in living animals
Fluorescence can be used for instance to analyze the regulation and expression of genes, to locate proteins in cells and tissues, to follow metabolic pathways and to study the location and migration o...
Medical Engineering | Read moreChemical genetics enables an approach to life phenomena and developments in drug discovery
This article reports on what is happening at the forefront of chemical genetics and chemical genomics, which are currently hot topics for both basic and applied research. Minoru YoshidaGro...
Life Sciences | Read moreUsing live fish, new tool a sentinel for environmental contamination
By measuring rates of oxygen use in developing fish, which are sensitive to contaminants and stressful conditions, the technology could reveal the presence of minute levels of toxic substances before ...
