For the first time, researchers have shown that an optical fiber as thin as a human hair can be used to create microscopic structures with laser-based 3-D printing. The innovative approach might one day be used with an endoscope to fabricate tiny biocompatible structures directly into tissue inside the body.
The Far Eastern or Amur leopard (Panthera pardus orientalis) is already among the rarest of the world's big cats, but new research reveals that it faces yet another threat: infection with canine distemper virus (CDV).
Lobachevsky University researchers are working to explore the mechanisms of adaptation of the nervous system to ischemic damage. Scientists say that under certain conditions, the brain's protective forces can be activated, even in some severe cases. According to Maria Vedunova, Director of the Institute of Biology and Biomedicine at Lobachevsky University, a large number of stressors affect the body by depleting its internal reserves and, as a consequence, leading to a number of diseases.
For the first time, research has uncovered the origins of the earliest domestic turkeys in ancient Mexico. The study also suggests turkeys weren't only prized for their meat -- with demand for the birds soaring with the Mayans and Aztecs because of their cultural significance in rituals and sacrifices.
A group of scientists from the Siberian Federal University (SFU, Krasnoyarsk, Russia) and the Nikolaev Institute of Inorganic Chemistry (NIIC, Novosibirsk, Russia) combined the useful properties of metal phthalocyanines and palladium membranes in order to create active layers in hydrogen detectors. This operation significantly increases the sensitivity of the sensors. The study is reported in the journals Dyes and Pigments and International Journal of Hydrogen Energy.
Aerosol indirect effect (AIE) can significantly affect climate change and is one of the largest uncertainties in climate change studies. To date, only a few AIE studies using satellite measurements have been carried out in China, and no such study has been done using ground-based measurements. The AIE can only be assessed accurately from aircraft or ground-based measurements. The first comprehensive investigation into the AIE over this polluted region is presented.
Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan have demonstrated that that moss can be a green alternative for decontaminating polluted water and soil. Published in PLOS One, the study shows that in particular, the moss Funaria hygrometrica tolerates and absorbs an impressive amount of lead (Pb) from water.
In a study covering 300 million years of evolutionary history, researchers from North Carolina State University and the North Carolina Museum of Natural Sciences found four necessary components to tail weapon development: size, armor, herbivory and thoracic stiffness.
Six novel chromosomal regions identified by scientists leading a large, prospective study of children at risk for type 1 diabetes will enable the discovery of more genes that cause the disease and more targets for treating or even preventing it.
A new peer-reviewed clinical trial to be published in the February edition of Regulatory Toxicology and Pharmacology shows that regular use of e-cigarettes does not have any negative health impact on smokers.
