The survey, which assessed knowledge of the prostate in 3,010 men over 50 years in the UK, Germany and France, found that just one in 4 men (26%) over the age of 50 are correctly able to identify the prostate's main function.
The pathogen Acinetobacter baumannii is one of three highest priority pathogens identified by WHO (World Health Organisation) for which new antibiotics are urgently needed
Understanding the enzymes that assemble antibiotics which can kill the pathogen is key to altering their structures to target the pathogen more effectively
It is generally accepted that planetary surfaces were covered with molten silicate, a "magma ocean", during the formation of terrestrial planets. In a deep magma ocean, iron would separate from silicate, sink, and eventually form a metallic core. In this stage, elemental partitioning between a metallic core and a magma ocean would have occurred and siderophile elements would be removed from the magma ocean. Such a chemically differentiated magma ocean formed the present-day Earth's mantle.
When the immune system fends off pathogens, this can happen in a very wide variety of ways. For example, the immune system's memory is able to distinguish a foreign protein with which the organism has already come into contact from another and to react with a corresponding antibody. Researchers have now investigated experimentally whether this ability of the immune system to specifically fend off pathogens can adapt in the course of evolution.
In January of this year, China's Chang'E-4 - the fourth version of a lunar spacecraft named for the Chinese goddess of the Moon - landed on the far side of the Moon. Due to the location of the landing, Chang'E-4 had to navigate autonomously, without the guidance of scientists on Earth.
Cooperation in mutual competition is a basic mechanism for the prosperity of human society. However, the simplest model of cooperation in game theory predicts that cooperation will not emerge among rational people because cooperative behaviors incur costs to cooperators, and free riding is a better option.
With the aid of highly advanced microscopes and synchrotron sources, researchers from the University of Copenhagen have gained seminal insight into how bacteria function as defence mechanisms against attacks from other bacteria and viruses.
The study, which has just been published in the renowned journal, Nature Communications, also describes how the defence systems can be activated on cue. This discovery can turn out to be an important cornerstone in fighting diseases in the future.
Aggregation-induced emission (AIE) was first reported by Tang`s group in 2001. Many research efforts have been devoted to the exploration structure-property-application of AIE. The focal points and hot spots of AIE are to design new structural systems and to illuminate the relationship of structural properties. Many new compounds with AIE characteristics have been designed and synthesized to enrich the members in AIE family. However, there are almost no reports thus far on the analog 1,1,2,4-tetraphenyl-1,3-butadiene (TPB) that was studied in AIE fields.
Highlights
The dorsal anterior cingulate cortex (dACC) causes motor performance deterioration due to anxiety
Transcranial magnetic stimulation of the dACC reduces the performance deterioration
This method could potentially be used to help athletes and musicians overcome anxiety
Abstract
Modern electronics is based on doped semiconductors. To synthesize electronic components, dopant atoms such as aluminum or phosphorus are embedded into crystals of ultrapure silicon. This allows for tailoring semiconductor conductivity according to the desired application. In modern electronic computer processors, miniaturized to just a few nanometers, only less than ten dopant atoms are relevant for the functionality.
