Team discovers new plant gene reprogramming mechanism
Researchers Albert Cairó and Karel Riha of the Central European Institute of Technology (CEITEC) and their colleagues have discovered a previously unknown mechanism that is responsible for reprogramming gene expression in plants during the transitio.....»»
Early-life acquisition of antimicrobial resistance in newborn children from low- and middle-income countries
Every year, almost 7 million potentially serious bacterial infections are estimated to occur in newborns, resulting in more than 550,000 annual neonatal deaths. Most of these infections and deaths happen in LMICs, where often scarce resources can lim.....»»
New study says dogs can ‘see’ with their noses
Dogs have always been well known for their ability to identify and track scents. A new study suggests that extensive connections within the dog’s olfactory pathway are responsible for this. Further, the study posits that dogs can see with their nos.....»»
Scientists use copper nanowires to combat the spread of diseases
An ancient metal used for its microbial properties is the basis for a materials-based solution to disinfection. A team of scientists from Ames National Laboratory, Iowa State University, and University at Buffalo developed an antimicrobial spray that.....»»
New strategy for iron fortification in rice
Iron (Fe) deficiency has become one of the factors limiting plant quality and productivity around the world. IMA (IRONMAN), a family of small peptides, has been recently reported to play a positive role in the Fe deficiency response in Arabidopsis an.....»»

Peptide "fingerprint" enables earlier diagnosis of Alzheimer"s disease
Neurodegenerative diseases like Alzheimer's disease or Parkinson's disease are caused by folding errors (misfolding) in proteins or peptides, i.e. by changes in their spatial structure. This is the result of minute deviations in the chemical composit.....»»
International team of astronomers discovers two rare binary star systems
An international team of astronomers has identified only the second and third examples of a rare type of star system comprising two central stars orbiting each other, encompassed by a remarkable disk of gas and dust......»»
Citizen scientist discovers a raft of ultracool binary stars
It's not only professional astronomers who make amazing discoveries about space -- sometimes enthusiastic amateurs make impressive scientific discoveries too......»»
Scientists Create Programmable Nanoparticle Toothbrush
Not only can these particles be transformed into tooth-cleaning shapes, but their action can have antimicrobial effects that destroy plaque-causing bacteria. The post Scientists Create Programmable Nanoparticle Too.....»»
Case solved: Researchers show how the poison nut tree forms strychnine
A research team at the Max Planck Institute for Chemical Ecology in Jena disclosed the complete biosynthetic pathway for the formation of strychnine in the plant species Strychnos nux-vomica (poison nut). The researchers identified all genes involved.....»»
Research team validates new method for assessing antimicrobial efficacy of domestic cleaning products
Environmental awareness in society is changing household laundry habits, where the use of less bleach and lower temperatures during washing machine cycles is encouraged. In this context, disinfectants added to detergents have become an essential fact.....»»
Team discovers signaling molecule that potently stimulates hair growth
University of California, Irvine-led researchers have discovered that a signaling molecule called SCUBE3 potently stimulates hair growth and may offer a therapeutic treatment for androgenetic alopecia, a common form of hair loss in both women and men.....»»
Researchers discover new endoplasmic reticulum sorting mechanism in plants
Protein sorting in the secretory pathway is essential for cellular compartmentalization and homeostasis in eukaryotic cells. The endoplasmic reticulum (ER) is the biosynthetic and folding factory of secretory cargo proteins. The cargo transport from.....»»
Rutgers Scientist Develops Antimicrobial, Plant-Based Food Wrap Designed To Replace Plastic
Aiming to produce environmentally friendly alternatives to plastic food wrap and containers, a Rutgers scientist has developed a biodegradable, plant-based coating that can be sprayed on foods, guarding against pathogenic and spoilage microorganisms.....»»
Cut and stretch assay reveals resistance genes
Which antimicrobial resistance genes are present in bacteria, for example in a hospital ward? For laboratories with limited financial resources characterizing bacterial DNA is difficult, as this often requires expensive equipment. Researchers at Chal.....»»

Exploring soy sauce"s salt-enhancing peptides
Soy sauce deepens the flavor of soup stocks, gives stir-fried rice its sweet-salty glaze and makes a plate of dumplings absolutely enjoyable. But what exactly makes this complex, salty, umami sauce so tasty? Now, researchers reporting in the Journal.....»»
Bacterial intimacy insights could help tackle antimicrobial resistance
One of the primary ways harmful bacteria acquire resistance to antibiotics is by receiving DNA from other bacteria that are already resistant. This DNA exchange is made via a process called conjugation, akin to bacterial sex, whereby two bacteria for.....»»
