A concentrated extract of maple syrup makes disease-causing bacteria more susceptible to antibiotics, according to laboratory experiments by researchers at McGill Univ. The findings suggest that combining maple syrup extract with common antibiotics could increase the microbes’ susceptibility, leading to lower antibiotic usage.
China has become the world’s largest exporter, leading to the country’s rapid economic development, and notorious pollution that’s harmful to human health. For the first time, scientists have estimated this trend’s health cost. They report in Environmental Science & Technology that in 2007, export-related emissions in China led to almost 160,000 deaths.
How does climate change affect the occurrence and distribution of species? This is a key question in the climate debate, and one that is hard to answer without information about natural variation in species abundance. Now researchers from Uppsala Univ. can, for the first time, give us a detailed picture of natural variation through study published in Current Biology.
Scientists at The Univ. of Manchester have discovered a way to make trees grow bigger and faster, which could increase supplies of renewable resources and help trees cope with the effects of climate change. In the study, published in Current Biology, the team successfully manipulated two genes in poplar trees in order to make them grow larger and more quickly than usual.
Zinc deficiency, long associated with numerous diseases like certain cancers, can lead to activation of the Hedgehog signaling pathway, a biomolecular pathway that plays essential roles in developing organisms and in diseases, according to new research at Rensselaer Polytechnic Institute.
A versatile instrument developed by Lawrence Livermore National Laboratory scientists and riding on the first spacecraft to ever orbit Mercury is causing researchers to rethink their theories on the planet’s formation. Known as the Gamma-Ray Spectrometer, or GRS, the instrument is part of a suite of seven instruments onboard NASA’s Mercury MESSENGER spacecraft.
Compared to industrial and residential construction, labs are expensive as they are highly complex in nature. The end goal to constructing a functional lab is to provide valuable research results. At the heart of a lab is the research conducted and, as a result, lab owners can’t compromise research efforts by overlooking key aspects of the workspace—such as safety, comfort and sustainability.
Much equipment used in nanotech, physical and biological sciences can’t function properly if subjected to vibrations that exceed small threshold values. As a result, lab designers are faced with the challenge of developing designs where vibration disturbances are within acceptable limits to further science.
Image analysis is of growing importance in science, and trends are observed for different layers of image acquisition. Quantifiable and reproducible data is a prerequisite for scientific publications. And, today, it isn’t sufficient to just acquire aesthetically pleasing images with a microscope. To get powerful scientific results, scientists must get as much information as they can from an image.
At my home workstation, I have an old Fluke handheld digital multimeter (DMM) in its classic orange case, along with a very old analog voltage ohm-meter (VOM) in its similarly classic boxy black plastic case. Both of these instruments sit on a shelf below my laser printer and see constant temperatures and environments all year long.
Just a few years ago, many researchers working in alternative manufacturing methods believed the basic layering technologies integral to 3D printing limited the capability of this technique to build quality optical devices and lenses. But, as rapidly evolving as these techniques are, and as broad ranging as the applications it’s infiltrating, this limitation has been surmounted by a number of research groups around the world.
Gel permeation/size exclusion chromatography (GPC/SEC) is a vital analytical technique used to characterize synthetic and natural polymers, including biologically important macromolecules such as proteins and DNA. Evolving challenges tax the capabilities of traditional GPC/SEC and invite advances in the technology.
At the 66th annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy (Pittcon) this past March 7 – 13 in New Orleans, the spectroscopy- based new product introductions covered, quite literally, the entire analytical spectrum from the far-infrared to x-rays, along with Raman and mass spectrometry (MS) and nuclear magnetic resonance (NMR) products.
A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels.
Researchers from North Carolina State Univ. and the Univ. of Colorado, Boulder, have developed a statistical model that allows them to tell where a dust sample came from within the continental U.S. based on the DNA of fungi found in the sample.
