Phys.org / Scientists uncover a hidden mechanism that drives RNA synthesis
Scientists have long been fascinated by two promising classes of antibiotics that disable RNA polymerase (RNAP). They knew that these drugs could grind gene expression to a halt in several pathogens, including the bacterium ...
Phys.org / New contactless method reveals how mirror-image materials respond differently to light
New research introduces a contactless way to see how mirror-image materials respond differently to circularly polarized light, without first building them into a complete electronic device. The researchers developed a novel ...
Phys.org / More than a decade of observation in Seattle suburbs shows where sensitive bird species won't go
Nearly 30 years ago, a simple question sent University of Washington researchers into the Puget Sound lowlands to look for birds. With Seattle's population swelling and housing developments pushing into once-forested suburbs, ...
Phys.org / Early farmers' larger grains may reflect rainfall, not genetic selection
A new archaeobotanical study by researchers from the University of Oxford and Kiel University (CAU) has revealed that increases in cereal grain size at the dawn of agriculture, more than 11,000 years ago, were initially driven ...
Phys.org / Can better civics education restore voter dissatisfaction over political corruption?
This summer, America celebrated the 250th anniversary of the signing of the Declaration of Independence, widely recognized as the formal founding of our nation and one of the early stages of establishing a democratic government.
Phys.org / Fungal chitin offers new route to tougher hydrogels for medical devices and soft robots
Researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) and the University of Tennessee (UT), Knoxville, have made an advance by using a natural substance from fungi called chitin to create hydrogels ...
Phys.org / X-ray analysis reveals the inner life of leaves while advancing engineering efforts to reduce 'crop sweat'
In the Midwestern summer, humans and plants have to breathe through the heat and humidity. Researchers hope that a retooled crop plant—one with an improved ventilation system within its leaves—could thrive while avoiding ...
Phys.org / Reading daily ocean temperatures from red algae
Understanding how marine ecosystems respond to a warming ocean requires detailed records of past temperatures. An international research team led by Johannes Gutenberg University Mainz (JGU) and the Max Planck Institute for ...
Phys.org / Decoding smell: Study reveals how wind transforms odor signals
Humans trust dogs to help find missing people, and bees to pollinate their crops. But scientists still don't fully understand how these animals use their extraordinary sense of smell to locate the source of an odor.
Phys.org / Beyond color: Fluorescence lifetime imaging distinguishes multiple proteins in living plant cells
Fluorescent protein imaging is an indispensable tool in life science research, enabling visualization of protein movement and localization, gene expression, signaling pathways, protein-protein interactions and more. For simultaneous ...
Phys.org / Color-sensing yeast could make biofactories more programmable and precise
Baker's yeast is one of biotechnology's most important microorganisms. It has long been used to leaven bread and ferment beer. More recently, advances in synthetic biology have enabled engineered yeast to convert sugar into ...
Phys.org / DNA origami nanosyringe actively transports molecules into synthetic cells
Transporting molecules across biological membranes is essential for life. In nature, this can occur through passive transport, known as diffusion. "Biological systems often use mechanical motion to accomplish tasks that cannot ...
