Phys.org / Machine learning helps detect roars from lion collars without recording actual audio
Roaring over long distances is a key behavior of lions. They communicate within prides as well as with other animals using distinct sequences of moans and grunts. Scientists from the GAIA Initiative have now published a machine ...
Phys.org / From air to tea: New sensor reveals invisible pollution in minutes
Fine particulate matter in the air or nanoparticles in water—a remarkable new technology developed at TU Wien makes it possible to detect tiny amounts of a wide range of substances in a very short time.
Phys.org / Why more gut and soil microbes could make ecosystems easier to predict
Much of the beauty—and challenge—of biology lies in its complexity. That's especially true in the microbial world, where hundreds or thousands of different bacterial species may co-exist in a patch of soil or in a section ...
Medical Xpress / Conversational AI uses trusted medical protocols to help people decide when to seek care
A new type of chatbot could reliably help people decide what to do about their symptoms—and do so based on guidance that is both medically sound and easy to understand. The chatbot could help reduce unnecessary hospital visits ...
Phys.org / Molecular chains unlock atomically precise nanoribbons for next-generation electronics
Scientists have developed a unique way to build electronic components so small they are made from chains of individual molecules—creating a toolbox to help build materials that could power the next generation of technology.
Phys.org / Turning vibrations into value—a new catalyst converts CO₂ into useful CO
Researchers at The University of Osaka have developed a catalyst that uses vibrational energy to convert carbon dioxide (CO2) into carbon monoxide (CO), an important industrial feedstock. The work, published in the Journal ...
Medical Xpress / Former tobacco executive takes CDC role
A new hire at the U.S. Centers for Disease Control and Prevention (CDC) is drawing backlash from public health experts who worry about his influence in the industry.
Medical Xpress / Tiny fiber probe monitors three key biomarkers at once, offering faster patient insight
A new fiber probe developed by researchers at The University of Texas at Austin delivers two major innovations in health monitoring to help both patients around the world and the clinicians who care for them. The probe can ...
Phys.org / Each protein in the epigenome produces a different pattern of gene expression, study finds
A new study finds the proteins responsible for controlling which genes are expressed in a genome do more than simply turn a gene on or off. Essentially, each type of protein that interacts with a gene produces different behaviors—a ...
Medical Xpress / Genetic test forecasts chemo response in breast cancer
A new study from Karolinska Institutet shows that gene analysis of breast cancer tumors can identify patients who do not benefit from chemotherapy given before surgery. The findings, published in the journal Nature Communications, ...
Medical Xpress / How does imagination really work in the brain? New explanation upends what we knew
Your brain is currently expending about a fifth of your body's energy, and almost none of that is being used for what you're doing right now. Reading these words, feeling the weight of your body in a chair—all of this together ...
Phys.org / Monkeys in Gibraltar self-medicate with soil to help them digest tourists' junk food
Monkeys in a tourism hotspot have learned that swallowing dirt can quell the upset stomachs caused by overconsumption of sweet and salty snacks fed to them by holidaymakers, a new University of Cambridge-led study suggests. ...
