A new type of methane-based, oxygen-free life form that can metabolize and reproduce similar to life on Earth has been modeled by a team of Cornell University researchers. Their theorized cell membrane, composed of small organic nitrogen compounds and capable of functioning in liquid methane temperatures of 292 degrees below zero, is published in Science Advances, Feb. 27.
Emory scientists have found NMDA receptor antagonists that can limit damage to the brain in animal models of stroke, apparently without the pronounced side effects seen with similar drugs.
Counter-intuitively, in vertebrates photoreceptors are located behind the neurons in the back of the eye. Now physicists explain why the neural wiring seems to be backwards.
A general law of how pedestrians interact in a crowd can be used to create realistic crowds in virtual reality games and to make public spaces safer.
Researchers have for the first time successfully converted adult human skin cells into neurons of the type that regulate appetite, providing a patient-specific model for studying the neurophysiology of weight control and testing new therapies for obesity.
Despite ever increasing regulation in drug approval and the rising costs of research, drug research and development remains unexpectedly efficient. This shows a study conducted by the European Center of Pharmaceutical Medicine at the University of Basel. The results have been published in the journal Nature Reviews/Drug Discovery.
Researchers have found one one possible explanation for some birds' ability to sense the earth's magnetic field and use it to orient themselves: a magnetically sensitive protein called cryptochrome that mediates circadian rhythms in plants and animals.
A team of Cornell University researchers focusing on a fictional zombie outbreak as an approach to disease modeling suggests heading for the hills, in the Rockies, to save your brains from the undead.
A strong electric field applied to a section of the Keystone pipeline can smooth oil flow and yield significant pump energy savings. Once aligned with an electric field, oil retained its low viscosity and turbulence for more than 11 hours before returning to its original viscosity. The process is repeatable and the researchers envision placing aligning stations spaced along a pipeline, significantly reducing the energy necessary to transport oil.
Researchers have long sought an efficient way to untangle DNA to study its structure -- neatly unraveled and straightened out -- under a microscope. Now, researchers at KU Leuven have devised a simple and effective solution: they inject genetic material into a droplet of water and use a pipet tip to drag it over a glass plate covered with a sticky polymer.
