A team of scientists, led by the University of Bristol, has developed a new photosynthetic protein system enabling an enhanced and more sustainable approach to solar-powered technological devices.
The initiative is part of a broader effort in the field of synthetic biology to use proteins in place of man-made materials which are often scarce, expensive and can be harmful to the environment when the device becomes obsolete.
Osaka, Japan - Despite its small size relative to the rest of the body, the eye is one of the most complex organs of the human body and has been difficult to study in a lab. Now, researchers from Osaka University have developed a novel method to model eye development and disease using human induced pluripotent stem cells (hiPSCs).
Researchers from Curtin University have used next generation DNA sequencing to learn more about the different species of plants, insects and animals present in the Pilbara and Perth regions of Western Australia.
Lead researcher Curtin PhD candidate Mieke van der Heyde, from the ARC Centre for Mine Site Restoration said that DNA metabarcoding is a growing field in the biological monitoring space, with the potential to provide fast, accurate, and cost effective assessments of biodiversity.
In the production of compounds, chemists have the fundamental goal of finding strategies that are most selective and avoid waste products. Breakthroughs in this area serve, among other things, to drive industrial innovation and drug development. In this context, allylic substitution reactions using catalysts made of so-called transition metals have already led to significant advances in science. The catalysts cause that in a molecule a functional group is replaced by another group in allylic position, i.e. in direct proximity to a carbon-carbon double bond.
A team of neuroscientists at Max Delbrueck Center for Molecular Medicine in the Helmholtz Association (MDC) have made an unexpected discovery about the way mice perceive warming sensations. It's counterintuitive: cooling receptors in the skin are critical for the perception of warmth.
The finding, recently published in the journal Neuron, challenges the predominant model of non-painful temperature perception, and provides clues about the way not just mice, but also humans, consciously detect warmth.
Scientists have revealed an important mechanism in the repair of DNA double-strand breaks, according to new research published today in eLife.
The discovery will help our understanding of why DNA repair processes do not work properly in some people, causing inherited diseases and cancer.
One of the main DNA repair processes is called homologous recombination (HR). This repairs a severe form of DNA damage where both strands of DNA are broken. A protein called Rad51 orchestrates HR, and Rad51 itself is supported by several 'helper' proteins.
The former coalfield of Geiseltal in Saxony-Anhalt has yielded large numbers of exceptionally preserved fossil animals, giving palaeontologists a unique window into the evolution of mammals 47 million years ago. A team led by the University of Tübingen and the Martin Luther University Halle-Wittenberg (MLU) has shown that the body size of two species of mammals developed in opposite directions. The study was published in "Scientific Reports".
With 3,000 known species and thousands more left to describe, the wasps of the subfamily Microgastrinae are the single most important group of parasitoids attacking the larvae of butterflies and moths, many of which are economically important pests. Consequently, these wasps have a significant impact on both the world's economy and biodiversity.
DURHAM, N.C. -- A professor at Duke University says that the way spilled milk spreads across the floor can explain why economic downturns regularly occur.
In a paper published online on March 5 in the International Journal of Energy Research, Adrian Bejan, the J.A. Jones Distinguished Professor of Mechanical Engineering at Duke, posits that recessions emerge as a natural feature of physics, rooted in the time-dependent movement of spreading over an area.
Since the discovery of penicillin in 1928 by Sir Alexander Fleming, antibiotics have saved millions of lives from fatal infections world-wide. However, with time bacteria have developed mechanisms to escape the effects of antibiotics - they have become resistant.
With fewer antibiotics available to treat resistant bacterial infections, the possibility of entering a pre-antibiotic era is looming ahead.
An international team of scientists studying lifespans of wild mammals have found that, just like humans, females tend to live significantly longer than their male counterparts.
The researchers looked at the lifespans of 101 different species, from sheep to elephants, and found that females lived an average of 18% longer than males for more than 60% of the species studies. In humans, females tend to live around 7.8% longer.
Nearly all older Americans support adding a dental benefit to the Medicare program that covers most people over age 65, according to a new national poll that also reveals how often costs get in the way of oral health for older adults.
In recent years, the development of CRISPR technologies and gene-editing scissors in particular have taken the world by storm. Indeed, scientists have learned how to harness these clever natural systems in the biotech and pharmaceutical industries, among other areas.
New research from the University of Copenhagen shows that we are not the first to find a way to exploit the benefits of the CRISPR technique. Apparently, primitive bacterial parasites have been doing so for millions of years.
Researchers from the University of Nebraska, University of Missouri, and Case Western Reserve University published a new paper in the Journal of Marketing that analyzes B2B e-negotiation communications in order to provide sellers with insights into buyers' behavioral responses to salespersons' communications.
The study, forthcoming in the March issue of the Journal of Marketing, is titled "B2B E-Negotiations and Influence Tactics" and is authored by Sunil Singh, Detelina Marinova, and Jagdip Singh.
A multi-university team of researchers found that expressive language sampling (ELS) can be useful in measuring outcomes in clinical trials targeting fragile X syndrome (FXS).
