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 / 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 / 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 ...
Medical Xpress / License to deliver: Some midwives break the law to assist with home births
In a midwife's suburban Atlanta home with a playground and chicken coop outside, Madie Collins lay on an examination table while the midwife measured her pregnant belly. Unlike at many a doctor's office, no crinkly paper ...
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 ...
Medical Xpress / Hippocampal ripples and replay reveal how brain recombines past knowledge for flexible planning
When facing new situations or problems, humans typically rely on knowledge they acquired in the past. Specifically, neuroscience studies suggest that the brain reorganizes past experiences and previously acquired knowledge, ...
Phys.org / RNA's first letter may shape antiviral alarms, with A outpacing G
Researchers at the International Institute of Molecular and Cell Biology in Warsaw (IIMCB), led by Prof. Gracjan Michlewski, have shown that a subtle difference at the very beginning of an RNA molecule can influence how strongly ...
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 / 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 ...
Medical Xpress / Analysis shows how using obesity drugs for weight loss is associated with a clinically relevant drop in blood pressure
A meta-analysis of 32 studies and 43,618 adults presented at the European Congress on Obesity in Istanbul, Turkey (May 12–15) shows that use of new classes of obesity drugs for weight loss is associated with a clinically ...
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 ...
Medical Xpress / New obesity guidance urges dietitian-led care as GLP-1 drugs reshape treatment
Obesity and dietitian societies have joined forces to issue a new consensus statement on recommendations surrounding the use of obesity drugs for weight loss treatment. The consensus statement was presented at the European ...
