Scientists have discovered that there is ice deep inside planets like Neptune and Uranus and want to find out what form it takes and how it behaves. They cannot dig for it and transport it all the way back to Earth, so they do the next best thing: recreate those extreme conditions in the lab.
Scientists have identified the mechanisms that allow plants to change their root anatomy to maximize survival when nutrients are scarce. The findings could pave the way for developing new ways to improve beneficial plant-microbe interactions in agriculture.
While chemical bonds usually determine the structure and properties of a material, bonds between neighboring metal atoms can also change as temperature or other conditions change. These changes can lead to unusual electronic and magnetic behaviors.
Life is not always easy for a bee: Not all plants place their pollen outside. Some flowers have to be set to vibrating before the pollen can get out of their tube-like stamens. Certain bee species have developed a special technique for this: They bite on the flower and use their flight muscles to generate rapid vibrations. The stamen is shaken and the pollen is released. This phenomenon is known as "buzz pollination."
When will the glacier in your valley disappear? Will the glacier you visited as a child still exist in 2050? And how much difference would limiting global warming make?
Does the academic discipline of a scientist's doctorate accurately capture their disciplinary affiliation decades later? Consider a scientist who earned a doctorate in physics 25 years ago who now studies climate change, publishes primarily in interdisciplinary journals and considers herself a climate scientist. Does "physics" still accurately describe where she fits in science?
Research teams from INRAE, the University of Clermont Auvergne and the CNRS have reconstructed 10 ancient genomes (paleogenomes) that are the common ancestors of 84 botanical species of agronomic interest. Their work makes it possible to identify particular genes, shared across different species of plants and retained throughout their evolutionary history, that might play a key role in adapting to environmental constraints such as drought.
Researchers from Aarhus University and the Danish Technological Institute have taken a new approach in the search for enzymes capable of breaking down some of the most difficult types of plastic to recycle. They collected millions of bacteria from a landfill in Kenya, Randers Regnskov Tropical Zoo, the guts of larvae and a compost heap near Aarhus—and examined their enzymes. They found 12 that work.
Researchers from the Institute of Microbiology of the Chinese Academy of Sciences (IMCAS) have characterized the structural and functional properties of the emerging SARS-CoV-2 sublineage BA.3.2.2 by studying RE.2.2, the lineage designation for the BA.3.2.2 branch gaining prevalence after prolonged low detection in European surveillance datasets.
New research shows how artificial intelligence, combined with advanced experimental science, can help find "hidden" and unexplored proteins in the human body and reveal what they actually do, according to a new study published in Nature.
An international team of scientists, including Donald Danforth Plant Science Center member emerita Elizabeth "Toby" Kellogg, Ph.D., has produced a chromosome-level genome assembly that offers a new view of the earliest evolution of grasses, the plant family that includes many of the world's most important food crops.
Metallic nanostructures are exceptionally effective at concentrating light into tiny volumes, while dielectric nanostructures excel at storing light with minimal energy loss. Combining these complementary properties has traditionally required complicated hybrid structures in which the two optical modes become mixed, making them difficult to control independently.
RhoBAST is a tiny RNA molecule that activates fluorescent dyes, enabling researchers to track RNA molecules in living cells with super-resolution. An international collaboration, which includes Ronald Micura and his team from the Institute of Organic Chemistry, has now shown that a small, local "nucleotide flip" within the RNA controls this fluorescence activation.
A new study suggests that the young stars orbiting the Milky Way's central black hole may have a surprisingly ordinary origin. But the black hole's influence may be what makes their origin look more exotic than it really is. Along with shaping their orbits, it may also destroy their stellar companions. The paper outlining this work was published in Astronomy & Astrophysics on Aug. 11.
Quantum computers promise to tackle problems that are extraordinarily difficult for today's computers. But there is a major obstacle: quantum systems are notoriously fragile. Noise, loss and even tiny disturbances can destroy the delicate behavior that gives them their power. Building systems with many quantum particles is also extremely challenging.
