Scientists of Far Eastern Federal University (FEFU) in partnership with colleagues from ITMO University, and universities in Germany, Japan, and Australia, have developed a method for precise, fast and high-quality laser processing of halide perovskites (CH3NH3PbI3), promising light-emitting materials for solar energy, optical electronics, and metamaterials. Structured by very short laser pulses (femtosecond laser) perovskites turned out to be functional nanoelements marked by unprecedented quality. A related article is published in Small.
Current marine protected areas in the Southern Ocean need to be at least doubled to adequately safeguard the biodiversity of the Antarctic, according to a new CU Boulder study published today, Earth Day, in the journal PLOS ONE.
Proposals under consideration by an international council this year would significantly improve the variety of habitats protected, sustain fish populations and enhance the region's resilience to the effects of climate change, the authors say.
New research demonstrates unsustainable levels of soil erosion in the UK.
The study examined more than 1,500 existing records and found 16% relating to arable (crop-growing) land showed erosion above "tolerable" levels - meaning rates of soil loss are significantly greater than new soil formation.
This may not reflect the national picture, as the study has highlighted that existing studies are frequently biased towards places which have eroded in the past.
22 April 2020 is National Stephen Lawrence Day which celebrates the life and legacy of the teenager who was killed in a racist attack at just 18 years old. A new report led by Sarah Page, Senior Lecturer in Sociology and Criminology, reveals concerns that racism experiences are still prevalent 27 years on.
From two seeds grew a thousand plants.
University of Guelph researchers used advanced cloning techniques to give the threatened Hill's thistle a fighting chance.
This cutting-edge propagation method could rejuvenate the population of other threatened and endangered plant species, said lead researcher Prof. Praveen Saxena, Department of Plant Agriculture.
High-calorie, energy-dense foods are constantly available in our modern society. Researchers at the Max Planck Institute for Metabolism Research in Cologne have discovered that a group of nerve cells in the brains of mice promotes the consumption of high-fat food. If these so-called nociceptin neurons in the hypothalamus are activated, the animals start to eat more.
Galaxies grow large by eating their smaller neighbours, new research reveals.
Exactly how massive galaxies attain their size is poorly understood, not least because they swell over billions of years. But now a combination of observation and modelling from researchers led by Dr Anshu Gupta from Australia's ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) has provided a vital clue.
In humans (as well as all other organisms) genes encode proteins, which in turn regulate all the different specific cellular functions of the body. The genetic information found in our DNA is first converted into messenger RNA (mRNA) by a process called transcription. The mRNA acts as a template as it is read by intracellular organelles called ribosomes, which then create (or translate) the appropriate protein from the correct amino acid components. miRNAs are short noncoding RNAs that do not make any protein.
ABERDEEN PROVING GROUND, Md. -- The Army has a new type of multi-polymer filament for commonly-used desktop 3-D printers. This advance may save money and facilitate fast printing of critical parts at the point of need.
The research is also the cover story of the April edition of Advanced Engineering Materials, a monthly peer-reviewed scientific journal.
In everyday life, our tissues, for example skin and muscle, are stretched, pulled and compressed without causing damage to the cells or the DNA. A team of researchers led by Sara Wickström from the Max Planck Institute for the Biology of Ageing and the CECAD Cluster of Excellence at the University of Cologne and the Helsinki Institute for Life Sciences at the University of Helsinki has now discovered that cells protect themselves from such stress by not only deforming the cell nuclei, but also softening the genetic material itself.
