Scientists computed a zoo of millions of alternate genetic polymer molecular structures, giving context for why biology encodes information how it does, and providing potential leads for new drugs and a guide to searches for extraterrestrial biology.
All cells in the body contain the same genetic material. The difference between cells therefore depends solely on which genes are expressed or ‘turned on’. Now, researchers from the University of Copenhagen have gained new insights into how genes are turned on and off and how the cells “forget their past” while developing into a specific cell in the body.
While Intermittent fasting may sound like another dieting craze, the practice of routinely not eating and drinking for short periods of time has shown again to lead to potentially better health outcomes.
Killer cells of the immune system detect and kill infected cells or cancer cells. Researchers at the Institute of Pathology at the University of Bern have now discovered that the mechanism by which certain immune cells kill their target cells can also be used to control the killer cells themselves. This finding may be relevant to cancer immunotherapy.
In a surprising finding using the standard animal model of Down syndrome (DS), scientists were able to correct the learning and memory deficits associated with the condition – the leading genetic cause of cognitive disability and the most frequently diagnosed chromosomal disorder in the U.S. – with drugs that target the body’s response to cellular stresses.
A bionic hand can be made to measure in 10 hours and can grip using a moveable thumb. Designers and engineers from WMG, University of Warwick and UK industry, have been able to entirely 3D Print the device with embedded electrical circuitry to seamlessly connect sensors and actuators.
