A ring-shaped molecule based on pillararene conjugated with benzoquinone has been developed, the powder of which selectively captures n-alkane gas molecule by host-guest complexation but not branched or cyclic alkane molecule. Upon forming such host-guest complex, its color changed from dark-brown to light-red, a chromophore-like behavior. The complex is highly-stable at room temperature and under atmospheric pressure. Thus, the new compound may serve as a sensor and/or a storage material for specific alkane molecules.
The Ben-Gurion U. researcher successfully redesigned a portion of MabThera, an FDA-approved drug used to treat certain autoimmune diseases and types of cancer, into a new molecule to treat ALS. 'Our experimental results on ALS transgenic mice showed a significant increase in life expectancy,' says Dr. Lichtenstein. 'Since the drug is already approved, we believe that we will only need limited preclinical testing to reach the clinical phase earlier than other initiatives.'
Every day 12 Australian diabetics have a limb amputated because of a non-healing wound. Globally, it's one every 30 seconds. A molecule produced by a Thai liver parasite could be the solution to those non-healing wounds -- and scientists from the Australian Institute of Tropical Health and Medicine are now able to produce a version of the molecule on a large enough scale to make it available for laboratory tests and eventually clinical trials.
A team of researchers from the University of Delaware have discovered how to label and light the sugar backbone of a bacterial cell wall. The findings will advance immune system research.
Geophysicist Zachary Eilon developed a new technique to investigate the underwater volcanoes that produce Earth's tectonic plates
Nanoengineers at the University of California San Diego have developed the first printed battery that is flexible, stretchable and rechargeable. The zinc batteries could be used to power everything from wearable sensors to solar cells and other kinds of electronics. The work appears in the April 19, 2017 issue of Advanced Energy Materials.
Researchers from the University of Missouri have found evidence of specific neurochemical changes associated with lower neuronal health in these brain regions. Further, they report that some of these changes in the brain may persist in individuals who receive hand transplants, despite their recovered hand function.
A new study looks at how three varieties of camelina perform when grown in two different regions within the Great Plains. The end goal is to find the camelina variety that performs best in each location or environment -- beyond the genetics involved.
Clostridium botulinum is the bacterium that causes the neurointoxication, which produces one of the most potent toxins on earth and is classified as a potential bioterrorism threat. While no cure exists -- and botulism treatment options are limited -- a serendipitous discovery by scientists at The Scripps Research Institute (TSRI) may provide a new therapy that can stop the neurotoxin even in its more severe, advanced stages of action.
Researchers at the University of Michigan, Stanford University and biotech company ConfometRx have captured the first cryo-electron microscopy snapshots of a key cellular receptor in action.
