The smells that newborn mice are exposed to (or "imprint" on to use the academic term) affect many social behaviors later in life, but how this happens is still a mystery. Scientists from Japan have now discovered the molecules necessary for imprinting. Their new study sheds light on the decision-making process and neurodevelopmental disorders such as autism spectrum disorders. It also proposes more effective use of oxytocin therapy for such disorders at an early age.
Artificial intelligence could be one of the keys for limiting the spread of infection in future pandemics. In a new study, researchers at the University of Gothenburg have investigated how machine learning can be used to find effective testing methods during epidemic outbreaks, thereby helping to better control the outbreaks.
Scientists from the Skoltech Space Center (SSC) have developed nanosatellite interaction algorithms for scientific measurements using a tetrahedral orbital formation of CubeSats that exchange data and apply interpolation algorithms to create local maps of physical measurements in real time. The study presents an example of geomagnetic field measurement, which shows that these data can be used by other satellites for attitude control and, therefore, provided on a data-as-a-service basis.
Light can be used to operate quantum information processing systems, e.g. quantum computers, quickly and efficiently. Researchers at Karlsruhe Institute of Technology (KIT) and Chimie ParisTech/CNRS have now significantly advanced the development of molecule-based materials suitable for use as light-addressable fundamental quantum units. As they report in the journal Nature Communications, they have demonstrated for the first time the possibility of addressing nuclear spin levels of a molecular complex of europium(III) rare-earth ions with light.
Researchers discovered a new fluorescent probe that can discriminate B lymphocytes over T lymphocytes without the cell receptor targetting antibodies.
Gallium nitride (GaN) semiconductors are considered to be a future alternative to silicon, not least due to their superior performance in fast switching applications. However, unwanted impurities in GaN crystals can degrade their switching performance. In a new study, scientists from Nagoya Institute of Technology, Japan explore the mechanism behind the impact of carbon impurities on the charge carriers of GaN, paving the way for impurity control strategies in GaN crystal growth.
Researchers have answered key questions to help prevent damage and improve the safety of hydraulic systems used for pipelines, water turbines and other applications.
A Korean research team succeeded in developing a technology generating various vibration using LED light signals. The technology allows various tactile sensations by area and reduction in size by considerably lowering the cost of light source, and these are expected to be applied to many industries including automobile and electronics.
Recent advances in tissue-clearing-based 3D imaging have permitted researchers to establish a new baseline 3D structure of the endometrial glands, including the formation of a rhizome network in the stratum basalis that expands horizontally along the muscular layer. These findings have implications in understanding the mechanisms underlying normal endometrial tissue processes such as menstruation and fertilized egg implantation, and in clarifying the pathogenesis of endometrium-related diseases, notably adenomyosis, endometriosis, and endometrial cancer.
What can vaccine proponents, clinicians and public health communicators learn from "anti-vaxxers?" A lot, according to new guidance for pro-vaccination social media events written by University of Pittsburgh health scientists. The five-part guidelines, published today in the journal Vaccine, arose from an analysis of a grassroots pro-vaccination campaign, #DoctorsSpeakUp, organized last year. Unexpectedly, more than three-quarters of the tweets associated with the event were opposing vaccination, researchers found.
