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 / 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 / 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 / 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 / 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 / Consistency-based rewards could build lasting cooperation better than punishing free-riders
A vaccine only protects a whole community if enough people get it, including those who would stay safe anyway once their neighbors are covered. The same tension runs through climate action and social movements: The shared ...
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 ...
Phys.org / Who are the secret gardeners of a parasitic plant?
In the coastal forests of a tropical Japanese island near Okinawa grows an inconspicuous plant that is easy to mistake for a mushroom. It is a non-green parasite that feeds on the roots of other plants and produces up to ...
Phys.org / Under-the-radar creeks could be sweeping carbon out of salt marshes
Salt marshes are coastal wetlands that are alternately inundated and exposed by tides. These marshes, like other coastal ecosystems, are hotspots of carbon cycling.
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 / 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 / Mars could have carried liquid water more recently than we thought
For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really the case, any liquid water would have long since either been locked ...
