Anthraquinones are a class of naturally occurring compounds prized for their medicinal properties, as well as for other applications, including ecologically friendly dyes. Despite wide interest, the mechanism by which plants produce them has remained shrouded in mystery until now. New work reveals a gene responsible for anthraquinone synthesis in plants. Their findings could help scientists cultivate a plant-based mechanism for harvesting these useful compounds in bulk quantities.
POSTECH-Stanford joint research team develops multimodal ion-electronic skin that distinguishes temperature from mechanical stimuli. This skin can detect various movements and is applicable in fields including humanoid skin and temperature sensors.
A team of scientists led by Berkeley Lab has designed a new material -- called ZIOS (zinc imidazole salicylaldoxime) -- that targets and traps copper ions from wastewater with unprecedented precision and speed. The technology offers the water industry and the research community the first blueprint for a water-remediation technology that scavenges heavy metal ions with a measure of control that far surpasses the current state of the art.
A team from the Institut national de la recherche scientifique (INRS) has demonstrated the effectiveness of an inexpensive molecule to fight antibiotic-resistant strains of the bacteria responsible for gonorrhea and meningococcal meningitis. These two infections affect millions of people worldwide. The results of this research, led by Professor Frédéric Veyrier and Professor Annie Castonguay, have just been published online in the Antimicrobial Agents and Chemotherapy journal.
A new therapy for influenza virus infections that may also prove effective against many other pathogenic virus infections, including HIV and COVID-19, has been developed by Purdue University scientists. The Purdue team's approach uses a targeted therapy approach against the virus infections.
A transmissible cancer in the Tasmanian devil has evolved over the past two decades, with some lineages spreading and replacing others, according to a new study in the open access journal PLOS Biology by Young Mi Kwon, Kevin Gori, and Elizabeth Murchison of the University of Cambridge (UK) and colleagues. The evolutionary dynamics of the cancer help explain how this Australian marsupial has become so quickly endangered, and may shed light on the evolution of other forms of cancer.
Mothers leave their mark on their children in many ways - and Melbourne researchers have discovered a protein called SMCHD1 is involved in this 'imprinting' process. SMCHD1 switches certain genes off, altering how a cell behaves. The new research has revealed that when an egg cell (or oocyte) is fertilised by a sperm, the egg cell's SMCHD1 lingers within the developing embryo, switching off at least 10 different genes and impacting the embryo's development - which could potentially have a lifelong impact on the offspring.
Understanding how the clear, watery substance flows through the brain could yield new insights into health and disease.
Rice University biochemists have proposed that degenerative diseases as varied as Alzheimer's, Parkinson's and muscle atrophy occur in two distinct phases marked by protein signaling changes that could result in patients responding differently to the same treatment.
Trace elements such as iron and zinc are essential micronutrients for all kinds of organisms. Below ice sheets, which cover around ten percent of the Earth's land surface, larger quantities of these substances are mobilised than previously assumed. This is shown by new data from Greenland and Antarctica, which were collected and analysed by an international research team led by Jon Hawkings from the GFZ German Research Centre for Geosciences and Florida State University (USA).
