Phys.org / Hidden small RNA in cholera bacterium helps determine whether it can infect humans
Scientists from St. Jude Children's Research Hospital have uncovered what gives Vibrio cholerae, the bacterium that causes cholera, the ability to colonize the human gut. The researchers found that a small RNA embedded within ...
Phys.org / Lobster embryo microbiomes remain resilient in future ocean conditions, sequencing reveals
As ocean temperatures rise and marine ecosystems change, scientists are working to understand how valuable species like the American lobster will respond. New research from William & Mary's Batten School of Coastal & Marine ...
Phys.org / Why is almost everyone right-handed? The answer may lie in how we learned to walk
It is one of the strangest puzzles in human evolution. About 90% of people across every human culture favor their right hand—with no other primate species showing a population-level preference on this scale. Despite decades ...
Phys.org / Physicists create hybrid light-matter particles that interact strongly enough to compute
Eighty years ago, Penn researchers J. Presper Eckert and John Mauchly launched the age of electronic computing by harnessing electrons to solve complex numerical problems with ENIAC, the world's first general-purpose electronic ...
Phys.org / Colonial roots may explain why North and Latin America treat wildlife differently
How people view and treat wild animals can vary dramatically from one part of the world to another. In the first international study of wildlife values, research led by Colorado State University found a distinct difference ...
Phys.org / Neuron imaging captures unconventional receptor route that supports synaptic communication
All cells, whether big or small, short or long, rely on proteins to function properly. In most cells, transporting these proteins is relatively simple. Neurons in the brain, however, face a significant logistical challenge ...
Phys.org / Implantable bacteria can now be safely contained, clearing a major hurdle for fighting infection and cancer
Researchers have long known that bacteria could potentially be used to deliver therapeutic drugs inside the human body. However, safely and successfully carrying out such a feat in humans has been a challenge. But now, researchers ...
Phys.org / Scientists identify hidden accelerant in Antarctic ice loss
For years, scientists have warned that melting Antarctic ice could push sea levels dangerously higher by the end of this century. But a new study led by University of Maryland scientist Madeleine Youngs suggests those warnings ...
Phys.org / Coal pollution is cutting solar power output worldwide, study finds
New research led by the University of Oxford and University College London (UCL) has revealed that pollution from coal-fired power plants is significantly reducing the energy output of solar photovoltaic (solar PV) installations, ...
Phys.org / Mathematical method calculates most efficient Earth-moon route yet
Researchers have developed a mathematical method that enables more precise calculations of the most economical travel routes between the orbits of celestial bodies. To demonstrate this method, they calculated a more efficient ...
Phys.org / New species of venomous box jellyfish discovered in Singapore
Finding highly venomous box jellyfish that are almost invisible in water is not an easy task—but researching them is crucial so that we can learn how to safely avoid them. Stings from these "sea-wasps" are extremely painful ...
Phys.org / Sustainable chemistry: Iron substitutes noble metals in catalytic reactions
The production of many products used in everyday life and in industry, such as pharmaceuticals, plastics, and coatings, requires chemical catalysts, often expensive noble metals with limited availability. Researchers at the ...
