Hookworms exploit a live fast/die young strategy in their South American fur seal pup hosts, report Morris Animal Foundation-funded researchers at the University of Georgia. As a result, they often kill their host, rather than finding a happy equilibrium. Scientists are concerned that this type of hookworm infection could eventually pose a risk to critically endangered populations of fur seals.
Scientists from The Graduate Center of The City University of New York (GC/CUNY) have made a major breakthrough in chemical synthesis that now makes it possible to quickly and reliably modify the 3D structure of molecules used in drug discovery, according to a paper appearing in the current issue of the journal Science. The new method allows scientists to employ cross-coupling reactions to generate new compounds while controlling their 3D architecture.
A global study addresses a major uncertainty in how saltmarshes and mangroves will respond to sea-level rise; stresses importance of preserving 'accommodation space' for landward migration.
Sample size (the number of individuals examined for a study) is the most important factor determining the accuracy of the study results.
A novel gut-to-brain neural circuit establishes the vagus nerve as an essential component of the brain system that regulates reward and motivation, according to research conducted at the Icahn School of Medicine at Mount Sinai and published Sept. 20 in the journal Cell.
A novel mathematical approach has uncovered that some animal cells have robust 12-hour cycles of genetic activity, in addition to circadian or 24-hour cycles.
In search of an option for the drug known for causing several side effects, scientists describe the anti-inflammatory properties of protein galectin-1 in tests with rats involving ischemia-reperfusion scenarios.
The University of Texas at Arlington has patented a smart seat cushion that uses changes in air pressure to redistribute body weight and help prevent the painful ulcers caused by sitting for long periods of time in a wheelchair. The same technology can be used to create prosthetic liners that adapt their shape to accommodate changes in body volume.
There's quite a story behind calaverite. Apart from its marked impact on the Gold Rush, the mineral has been a headache and a great paradox for crystallographers for decades. The deeper researchers dug into it, the more new questions came up. Scientists from Russia and Germany have succeeded in interlacing all the oddities of calaverite within a simple model, so experimenters can now hunt for the new compound they predicted, AuTe, unknown until now.
The United States Department of Agriculture-National Animal Health Monitoring System (USDA-NAHMS) conducted a survey of 2,545 preweaned heifer calves across 104 dairy operations in 2014. The study, which took place in 13 states over 18 months, covered a large cross-section of management of preweaned heifer calves in the United States, and the results have been published in six new articles in the October issue of the Journal of Dairy Science.
