Deep learning to analyze neurological problems
Nearly 200 years ago, Henry Wadsworth Longfellow asserted "Music is the universal language of mankind." Today, scientists at Harvard have published the most comprehensive scientific study to determine if the American poet's words were mere cliché, or cultural truism.
Nature's secret recipe for making leaves
Getting to the doctor's office for a check-up can be challenging for someone with a neurological disorder that impairs their movement, such as a stroke. But what if the patient could just take a video clip of their movements with a smart phone and forward the results to their doctor? Work by Dr. Hardeep Ryait and colleagues at CCBN-University of Lethbridge in Alberta, Canada, publishing November 21 in the open-access journal PLOS Biology, shows how this might one day be possible.
Magnesium deprivation stops pathogen growth
The secret recipe nature uses to make the diverse leaf shapes we see everywhere around us has been revealed in research.
Dung beetle discovery revises biologists' understanding of how nature innovates
When pathogens invade cells, our body combats them using various methods. Researchers at the University of Basel's Biozentrum have now been able to show how a cellular pump keeps such invading pathogens in check. As the researchers report in Science, this pump causes a magnesium shortage, which in turn restricts bacterial growth.
Red tide grew drastically along Florida's west coast in less than a month
When studying how organisms evolve, biologists consider most traits, or features, as derived from some earlier version already present in their ancestors. Few traits are regarded as truly "novel."
NASA found Atlantic's Sebastien was fighting wind shear
In a little less than three weeks, red tide bloom intensified greatly along Florida's west coast, according to the Florida Fish and Wildlife Conservation Commission's Wednesday report.
Building better bacteriophage to combat antibiotic-resistant bacteria
NASA's Terra satellite captured a visible image of Tropical Storm Sebastien that showed wind shear had pushed the bulk of its clouds and showers to the southeast of the center.
Mathematician develops model to control spread of aquatic invasive species
Researchers are pursuing engineered bacteriophage as alternatives to antibiotics to infect and kill multi-drug resistant bacteria. The potential for an innovative synthetic biology approach to enhance phage therapeutics and the role a biofoundry can play in making this approach feasible and effective is discussed in an article in PHAGE: Therapy, Applications, and Research.
Exposing office distractions and effects on worker productivity
Adjusting the water flow rate in a river can prevent invasive species from moving upstream and expanding their range. An applied mathematician at UT has developed a partial differential equation model to find the desired flow rate to reduce invasive populations.
Life under extreme conditions at hot springs in the ocean
With seemingly endless emails, phone calls and meetings, it's no secret that working in an office environment can be quite stressful. Understanding how stress manifests by exposing the effects of distractions can help unlock an office workers' full potential, according to new data collected by researchers from three university laboratories.
Using controlled environment food production to solve food shortages
The volcanic island of Kueishantao in northeastern Taiwan is an extreme habitat for marine organisms. With an active volcano, the coastal area has a unique hydrothermal field with a multitude of hot springs and volcanic gases. The acidity of the study area was among the highest in the world. The easily accessible shallow water around the volcanic island therefore represents an ideal research environment for investigating the adaptability of marine organisms, some of which are highly specialised, such as crabs, to highly acidified and toxic seawater.
'Dream team' to study ice loss on Greenland glacier to better forecast rising oceans
A review of the literature led by researchers from the University of Florida attempts to provide clarification and analysis on various aspects of what a controlled environment system entails and the extent to which differing food production approaches can be applied to the many current and hopeful endeavors of Urban Agriculture.
New twist in quest to develop understanding of time crystalline behavior
Last month a new projection of sea-level rise by the year 2050 spurred headlines showing more coastal cities around the world will be submerged than earlier models have predicted. Just how fast and how high sea levels rise globally will be determined by the melting of ice sheets in Greenland and Antarctica. However, the acceleration, retreat and thinning of glaciers where they meet ocean water are still understood poorly.
Back on all fours—Ronda the dog's pioneering prosthetic surgery
The quest to develop the understanding for time crystalline behaviour in quantum systems has taken a new, exciting twist.
NASA imagery indicates a dissipating Kalmaegi
Ronda seemed doomed. The six-year-old French mastiff had developed a tumour on her paw that required amputation and the fitting of a prosthetic leg—a rare and complex operation.
Researchers visualize bacteria motor in first step toward human-produced electrical energy
NASA's Aqua satellite captured an image of Tropical Depression Kalmaegi in the South China Sea as it was dissipating.
Illinois researcher's theory of pore-scale transport to enable improved flow batteries
Humans, one day, may be able to produce their own electrical energy in the same way electric eels do, according to a research team based in Japan. It's the ultimate goal that begins with understanding precisely how tiny "motors" inside bacteria maintain biological balance.
Growing length of manifestos casts new light on electioneering history
Redox flow batteries are an emerging technology for electrochemical energy storage that could help enhance the use of power produced by renewable energy resources. These power resources are inherently irregular in their supply, which doesn't typically align with demand on the power grid. In principle, redox flow batteries can be designed to have an energy-storage capacity that is independent of its power rating. However, in practice, the ease with which redox-active molecules are transported to electrode surfaces plays an important role in determining their efficiency, the power that is produced or charged and, in some instances, their length of life.
Escher's angels and demons woodcut predicts how matter deforms
From a modest 150 words to the length of a children's book—the number of words used by politicians in their election manifestos has grown substantially in the past century, new research shows.
Researchers uncover critical metabolic switch for inflammatory diseases
Dutch artist M.C. Escher's most famous drawing, "Circle Limit IV (Heaven and Hell)", shows angels and demons in a tessellation that fills a circle without empty spaces. This masterful woodcut inspired an international partnership of researchers including Politecnico di Milano Physics Department to author the cover-story article published in Physical Review Letters.
Self-restrained genes enable evolutionary novelty
A research team in Trinity College Dublin has uncovered a critical role for a protein called 'PKM2' in the regulation of immune cell types at the heart of multiple inflammatory diseases.
Unraveling gene expression
Changes in the genes that control development can potentially make large contributions to evolution by generating new morphologies in plants and animals. However, because developmental genes frequently influence many different processes, changes to their expression carry a risk of "collateral damage." Scientists at the Max Planck Institute for Plant Breeding Research in Cologne and collaborators have now shown how gene self-repression can reduce the potential side effects of novel gene expression so that new forms can evolve. This self-regulation occurs via a distinctive molecular mechanism employing small regions of genomic DNA called low-affinity transcription factor binding sites.
The simultaneous merging of giant galaxies
The DNA of a single cell is two to three meters long end-to-end. To fit in the nucleus and function correctly, DNA is packaged around specialized proteins. These DNA-protein complexes are called nucleosomes, and they are a small part of a larger structure called chromatin. Nucleosomes can be thought of as the cell's DNA storage and protection unit.
Magnetic wave flows under better control from now on
An international research team led by scientists from Göttingen and Potsdam proved for the first time that the galaxy NGC 6240 contains three supermassive black holes. The unique observations, published in the journal Astronomy & Astrophysics, show the black holes close to each other in the core of the galaxy. The study points to simultaneous merging processes during the formation of the largest galaxies in the universe.
Even faster processors with even smaller dimensions? Wherever neither electronics nor spintronics can cope with performance or miniaturization, magnonics comes to the rescue. But before that happens, scientists must learn how to accurately simulate the flow of magnetic waves through magnonic crystals. At the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow an important step in this direction has just been made.
