New guidelines recommend limited sugar intake to prevent impaired memory function in children Sugar practically screams from the shelves of your grocery store, especially those products marketed to kids. Children are the highest consumers of added sugar, even as high-sugar diets have been linked to health effects like obesity and heart disease and even impaired memory function. However, less is known about how high sugar consumption during childhood affects the development of the brain, specifi...

Study shows how collective behavior of bacterial colonies may contribute to antibiotic resistance The bacterial equivalent of a traffic jam causes multilayered biofilms to form in the presence of antibiotics, shows a study published today in eLife. The study reveals how the collective behavior of bacterial colonies may contribute to the emergence of antibiotic resistance. These insights could pave the way to new approaches for treating bacterial infections that help thwart the emergence of res...

Study reveals new mechanism by which hair follicles lose their regenerative capabilities Hair grows from stem cells residing in hair follicles. During aging, the capability of hair follicles to grow hair is successively lost, leading to hair thinning and ultimately hair loss. In a new study, researchers from Tokyo Medical and Dental University (TMDU) and the University of Tokyo identified a novel mechanism by which hair follicles lose their regenerative capabilities. Hair follicles are mini-org...

Study Seeks to Determine the Best Materials for Future Electronics Written by AZoMMar 17 2021 At the Institut national de la recherche scientifique (INRS), the aim of Professor Emanuele Orgiu is to determine the best materials for future electronics. Some of the materials in which Professor Orgiu shows interest are made of molecules with the ability to conduct electricity. Image Credit: Adobe Stock Photo. Emanuele has illustrated the role of molecular vibrations on electron conductivity on crys...

New Voltage-Controlled Nanopores Could Help Create Single-Molecule Sensors Written by AZoNanoMar 15 2021 At the Institute of Scientific and Industrial Research of Osaka University, researchers have fabricated nanopores in silicon dioxide with a diameter of just 300 nm and encapsulated by electrodes.

Black women have 80% higher risk of preterm birth between 32 and 33 weeks of pregnancy if a Black person who lives in their neighborhood is killed by police during the pregnancy, according to a study by researchers at UC San Francisco and UC Berkeley.

Novel tool can add or remove sugar from proteins Sugar has been called "evil," "toxic," and "poison." But the body needs sugars, too. Sugar molecules help cells recognize and fight viruses and bacteria, shuttle proteins from cell to cell, and make sure those proteins function. Too much or too little can contribute to a range of maladies, including neurodegenerative diseases like Alzheimers, inflammation, diabetes, and even cancer. About 85 percent of proteins, including those associated with Al...

New Crush-Resistant Metamaterials can Prevent Failure of Structures Written by AZoMMar 12 2021 A chain reaction of locally restricted damage can inevitably lead to a catastrophic breakdown of structures and materials. Such a failure can be seen in many structures, from metal space trusses that collapse after the warping of a solo strut to solid ceramics that breakdown after the development of a tiny crack. Novel tensegrity metamaterials by UCI and Georgia Institute of Technology researchers emp...

Study: Graphene nanoparticles interfere with the development of anxiety-related behaviors in vertebrates New research shows that the nanomaterial acts on the excitatory synapses, interfering with the development of anxiety related behaviors in vertebrates. Effective, specific, with a reversible and non-harmful action: the identikit of the perfect biomaterial seems to correspond to graphene flakes, the subject of a new study carried out by SISSA - International School for Advanced Studies of Tri...
