Researchers at Carnegie Mellon University have developed an automated, robotic training device that allows mice to learn at their leisure. The technology stands to further neuroscience research by allowing researchers to train animals under more natural conditions and identify mechanisms of circuit rewiring that occur during learning.
The widespread adoption of thermoelectric devices that can directly convert electricity into thermal energy for cooling and heating has been hindered, in part, by the lack of materials that are both inexpensive and highly efficient at room temperature. Now researchers from the University of Houston and the Massachusetts Institute of Technology have reported the discovery of a new material that works efficiently at room temperature while requiring almost no costly tellurium, a major component of the current state-of-the-art material.
Porous metal-organic frameworks (MOFs) have many applications like carbon capture and water-cleaning. However, MOFs with large pores tend to collapse. Chemists and chemical engineers at EPFL have now solved the problem by adding small amounts of a polymer into the MOF pores, an act that impedes pore collapse.
Researchers in the group of Jan Michiels (VIB-KU Leuven Center for Microbiology) identified a mechanism of how sleepy bacteria wake up. This finding is important, as sleepy cells are often responsible for the stubbornness of chronic infections. Findings published in Molecular Cell reveal new perspectives on how to treat chronic infections, for example by forcing bacteria to wake up.
NUS researchers have developed an ultra responsive and robust artificial nervous system for e-skins.
Software that purportedly reads emotions in faces is being deployed or tested for a variety of purposes, including surveillance, hiring, clinical diagnosis, and market research. But a new scientific report finds that facial movements are an inexact gauge of a person's feelings, behaviors or intentions.
Researchers at the Georgia Institute of Technology are working on membranes that could separate chemicals without using energy-intensive distillation processes.
Many of the deadliest or most common cancers get the least amount of nonprofit research funding, reports a new Northwestern Medicine study. 'Embarrassing' or stigmatized cancers, like lung and liver, are underfunded. Colon, endometrial, liver and bile duct, cervical, ovarian, pancreatic and lung cancers were all poorly funded compared to how common they are and how many deaths they cause, the study found. In contrast, breast cancer, leukemia, lymphoma and pediatric cancers were all well-funded, respective to their impact on society.
Most magnets are rigid but have made great contributions to society and to modern industry, says Thomas Russell of UMass Amherst. But this award-winning innovator dreamed of more -- what if magnets could be soft and flowable as liquid to conform to a limited space? In Science this week, he and Xubo Liu from Beijing University of Chemical Technology, others at Berkeley National Lab and UC Berkeley, report on a simple way to transform paramagnetic ferrofluids -- plain metal particles in suspension -- into a magnetic state.
Under physiological conditions, only certain sequences within the genome, called flipons, are capable of dynamically forming either right- or left-handed DNA. When a flipon is left-handed, genes change the transcripts they produce, affecting how cells respond to their environment. The outcomes depend on both the shape and sequence of a gene's DNA, each feature encoding a different subset of genetic information: one dynamic, the other static. Both flipons and codons are subject to natural selection.
