Until now, the basis of day-to-day research work in cell-based laboratories involved the tending of cell cultures by hand. Scientists in Dresden have now created system that completely automates the process of cultivating cells, offering the potential for faster research.
Researchers at Lawrence Livermore National Laboratory recently received $3 million from the National Institutes of Health to acquire a new biomedical accelerator mass spectrometry (bioAMS) instrument. The instrument will provide faster analysis for medical and other biological research.
When a small bug landed on Dr. Igor Siwanowicz's hand and began "fiercely digging its mandibles" into his skin, he didn't swat it away. Instead, he captured and began taking photomicrographs. To his surprise, the image took first place in the 2011 Nikon Small World competition.
Imaging sensor chips that form the heart of built-in cameras helped engineers at the California Institute of Technology create a "smart" petri dish. The ePetri is a compact, lens-free microscopy imaging platform that does away with the need for bulky microscopes and significantly reduces labor for the researcher.
A team of researchers from the University of California, Davis has accomplished the MacGyver-esque task of using everyday iPhones to accomplish high-quality medical-quality imaging and chemical detection. The key is adding spectrometry to the smart phone’s optics.
A technique scientists at the Stanford Linear Accelerator Center invented for scanning ancient manuscripts is now being used to probe the human brain, in research that could lead to new medical imaging methods and better treatments for stroke and other brain conditions.
New drug delivery systems, solar cells, industrial catalysts, and video displays are among the potential applications of special particles that possess two chemically distinct sides. These particles are named after the two-faced Roman god Janus and their twin chemical faces allow them to form novel structures and new materials. However, as scientists reduced the size of Janus particles their efforts have been hampered because they lacked an accurate way to map the particles surfaces. Until now.
Using functional magnetic resonance imaging and computational models, University of California, Berkeley researchers have succeeded in decoding and reconstructing people’s dynamic visual experiences—in this case, watching Hollywood movie trailers.
Imagine a microscopic jet vacuum cleaner, the size of a pen nib that hovers over cell surfaces without ever touching them. Then picture the jet delivering various molecules selectively to the cells. A new device matching this description has been built by McGill University technologists to study a range of cellular processes.
Weighing about as much as a medium-sized banana and fitting easily in the palm of a hand a compact, lightweight dual-mode microscope made by researchers at the University of California, Los Angeles using mass-produced electronics can achieve a spatial resolution of 2 ?m.
Loss of bone mass is the well-established reason that bones become more brittle as we grow older. At microscopic dimensions, however, researchers at Lawrence Berkeley National Laboratory have found that age-related loss bone quality can be just as important as loss in quantity.
Over the past decade, federal research laboratories such as Lawrence Livermore National Laboratory have shifted from Cold War-era defense R&D to meeting the challenges of new terror threats, developing a nationwide system to sniff the air for germs such as anthrax and smallpox.
A team of scientists from The Scripps Research Institute have successfully reengineered an important antibiotic to kill the deadliest antibiotic-resistant bacteria. The researchers report the finding has clinical significance.
Research based at Princeton University has revealed that newly fertilized cells only narrowly avoid degenerating into fatal chaos. Embryos have also acquired a mechanism to contain this dangerous instability, a finding that could help biologists unravel other mysteries about the first hours of life.
How exactly the hippocampus manages to string together events that are part of the same experience but are separated by "empty" periods of time has been a complete mystery to science. New research, however, has found the neurons that encode sequential moments in a discrete experience.
Researchers from Duke University and The Scripps Research Institute have identified a molecular pathway that plays a key role in stress-related damage to the genome. Until this new study, exactly how chronic stress wreaks havoc on DNA was basically unknown.
For the first time, microbiologists have identified the structure of the bacterial enzyme that decomposes nitrous oxide, a potent greenhouse gas, and they have also decoded the decomposition mechanism.
Ultraviolet light from space was damaging to many prebiotic molecules in Earth’s early history, but some were photostable and survived the assault. Recent research shows that one of these building blocks of DNA and RNA, adenine, has an unexpectedly variable range of ionization energies along its reaction pathways.
With five times the tensile strength of steel, spider thread is a fascinating material. Yet, attempts to produce the material on an industrial scale have failed. Researchers in Germany have unlocked the protein structure of this thread, a finding that could open the door to artificial spider silk.
Both bone and wood are solid, living elements with an internal structure that is porous. By transforming red oakwood into a charcoal substance that emulates bone, scientists in Europe may have discovered a weight-bearing implant that will help regenerate bone.
A researcher at the University of the Basque Country has developed and validated a polymer support capable of inducing neuronal differentiation in vitro. Created with a photolithographic technique, the support structure is biocompatible and has been tested on animal models.
Coffee-based sunscreen may not be so crazy after all. Several years ago, researchers discovered that caffeine has a positive effect against certain types of skin cancers at the molecular level. A new study from Rutgers University strengthens this theory.
New findings, resulting from a decade of research, show striking recurring patterns of marine virioplankton dynamics in the open sea, which have implications regarding our understanding of cycling of nutrients in the world's oceans.
GE Healthcare and AB SCIEX announced a collaboration agreement to provide GE Healthcare's Smart Asset Management Services (SAMS) customers throughout North America with the option for full on-site service and maintenance support of AB SCIEX mass spectrometry systems.
To successfully fight infection, the right treatment must be started quickly. But sometimes physicians have difficulty differentiating between a viral or a bacterial affliction. A simple blood test has been developed that should quickly answer this question.
