How much energy does a dolphin use to swim?
From foraging for prey to evading predators, ship strikes or other dangers, a dolphin's survival often hinges on being able to crank up the speed and shift its swimming into high gear......»»
Examining how stellar threats impact the habitable zone of exoplanets
When we think of exoplanets that may be able to support life, we home in on the habitable zone. A habitable zone is a region around a star where planets receive enough stellar energy to have liquid surface water. It's a somewhat crude but helpful fir.....»»
Scientists calculate predictions for meson measurements
Nuclear physics theorists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have demonstrated that complex calculations run on supercomputers can accurately predict the distribution of electric charges in mesons, particles made.....»»
The high cost of complexity: New study explores energy needs of multicellular life
Between 1.8 billion and 800 million years ago, earthly life was in the doldrums. During this period, called the "boring billion," the complexity of life remained minimal, dominated by single-celled organisms with only sporadic ventures into multicell.....»»
Direct synthesis method uses recovered carbon dioxide and hydrogen to produce formic acid
With the goal of achieving a carbon-neutral society and eliminating greenhouse gas emissions by 2050, efforts are accelerating to utilize hydrogen as a key energy source. To achieve this goal, the technologies for hydrogen storage, transportation, an.....»»
Scientists use high-energy heavy ion collisions as a new tool to reveal subtleties of nuclear structure
Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at DOE's Brookhaven National La.....»»
Bioinspired hydrogels harness sunlight: A step closer to artificial photosynthesis
Mimicking how plants convert sunlight into energy has long been a dream for scientists aiming to create renewable energy solutions. Artificial photosynthesis is a process that seeks to replicate nature's method, using sunlight to drive chemical react.....»»
Study identifies promising materials for fusion reactors
Nuclear fusion could be an ideal solution to mankind's energy problem, guaranteeing a virtually limitless source of power without greenhouse gas emissions. But there are still huge technological challenges to overcome before getting there, and some o.....»»
Cells have more mini "organs" than once thought—these rogue organelles challenge biology"s fundamentals
Think back to that basic biology class you took in high school. You probably learned about organelles, those little "organs" inside cells that form compartments with individual functions. For example, mitochondria produce energy, lysosomes recycle wa.....»»
Another way to extract energy from black holes?
The gravitational field of a rotating black hole is powerful and strange. It is so powerful that it warps space and time back upon itself, and it is so strange that even simple concepts such as motion and rotation are turned on their heads. Understan.....»»
Archaic dolphin could hear high frequency sounds
A team of researchers led by SNSB paleontologist Gertrud Rößner has discovered a new prehistoric dolphin species. Analyses of its inner ear confirm that this dolphin had excellent hearing abilities in the high-frequency range, which is very similar.....»»
Artificial intelligence: A double-edged sword for the environment?
As AI technology progresses, the energy demands of training complex AI models have surged, raising widespread concerns about associated carbon emissions. This rapid growth is fueled by global demand across industries and academia, leading to exponent.....»»
Study reveals effect of slope position on nonstructural carbohydrates in biological soil crusts
Nonstructural carbohydrates (NSCs) provide energy for metabolic processes in plants and play a key role in plant growth, defense and osmoregulation. However, the regulation of NSC in biological soil crusts across different slope positions remains unc.....»»
Saturday Citations: On chimpanzee playwrights; the nature of dark energy; deep-diving Antarctic seals
This week, researchers reported the world's second-tiniest toad, winning the silver in the Brachycephalus contest. Chemists at UCLA disproved a 100-year-old organic chemistry rule. And researchers in Kenya report that elephants don't like bees, which.....»»
The reasons flowers wilt could explain how plants spend (and save) their energy
Wilting flowers might not signal poor flower or plant health, but rather the effects of a sophisticated resource management strategy in plants, millions of years in the making......»»

New method successfully recycles carbon fiber composite into reusable materials
USC researchers have developed a new process to upcycle the composite materials appearing in automobile panels and light rail vehicles, addressing a current environmental challenge in the transportation and energy sectors. The study recently appeared.....»»
Solar-powered animal cells: Combining chloroplasts from algae with hamster cells
Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining chloroplasts (chlorophyll containing structures in.....»»
Stochastic thermodynamics may be key to understanding energy costs of computation
Two systems exist in thermal equilibrium if no heat passes between them. Computers, which consume energy and give off heat as they process information, operate far from thermal equilibrium. Were they to stop consuming energy—say you let your laptop.....»»
Advanced graphics processing units lead to unprecedented speed for electronic structure calculations
A recent collaboration among researchers from HUN-REN Wigner Research Center for Physics in Hungary and the Department of Energy's Pacific Northwest National Laboratory, along with industry collaborators SandboxAQ and NVIDIA, has achieved unprecedent.....»»
