Medical Xpress / The nocebo effect: How prior experience and verbal suggestion rewire the brain to make pain worse
Researchers have a better understanding of the nocebo effect and the neuroscience behind it all. Opposite of the better-known placebo effect, where positive expectations trigger genuine pain relief, the nocebo effect is the ...
Medical Xpress / Three medical routines that older people may not need
Enough time had passed since the patient's previous colonoscopy that she met the criteria to undergo another, said Dr. Steven Itzkowitz, a gastroenterologist at the Icahn School of Medicine at Mount Sinai in New York.
Medical Xpress / Parkinson's symptoms trace to distinct brain circuits
Parkinson's disease is often treated as a single disorder. But for the more than 1.1 million people living with it in the United States, the disease can look different from one person to the next. Research from Carnegie Mellon ...
Phys.org / Canadian Rockies study shows that spruce trees adapt to rugged peaks and boreal flatlands in a similar way
If you look at the trees as you're driving on the Trans-Canada Highway toward Banff National Park, you will see Englemann spruce on the cooler, wetter northeast-facing slopes of the Three Sisters. Across the valley—on the ...
Phys.org / Imaginary-time technique speeds X-ray scattering simulations by 50-fold for extreme matter
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed a new procedure, enabling them to speed up elaborate computer simulations that analyze matter under extreme conditions. In particular, this work ...
Phys.org / Low pH outside cells rewires transport network and displaces Golgi apparatus, study finds
A new study led by the Universidad Carlos III de Madrid (UC3M) describes the mechano-chemical mechanism by which the acidity of the cellular environment destabilizes microtubules, the "avenues" that organize internal cellular ...
Medical Xpress / Immune memory cells in ovarian cancer produce tumor-targeting antibodies, opening a vaccine path
While we tend to quickly forget having been ill or having received a vaccine, the immune system remembers remarkably well. It has memory B cells—"trained" immune cells that circulate throughout the body in search of harmful ...
Phys.org / Ice may release more iron than climate models predict
Most people think of ice as frozen and lifeless, but research at Umeå University shows the opposite. A new study published in the Proceedings of the National Academy of Sciences demonstrates that ice actively speeds up the ...
Phys.org / ATLAS observes new Bc meson excited state
Protons and neutrons—the building blocks of matter—belong to a huge class of particles called hadrons. Hadrons are composite particles made of quarks that are bound together by the strong force. They are classified into two ...
Phys.org / Entanglement injuries cause prolonged suffering for whales and dolphins—early intervention is crucial
When a humpback whale became entangled in a craypot line off Kaikōura last week, witnesses described it thrashing in distress for ten minutes before eventually freeing itself.
Phys.org / Metal-free method unlocks selective carborane editing for cancer therapy and sensors
Carboranes are molecules composed of carbon, boron and hydrogen atoms that are proving to have applications of great interest in chemistry, materials science and biomedicine. They are being used, for example, in the fight ...
Phys.org / 190,000 baby trees in 25 years: Seedling census offers clues to what the future might hold for Michigan forests
The history of a forest might be measured by the trunks and branches looming overhead. But for some researchers at Michigan State University, a forest's future lies in what's growing under their feet. Every summer for nearly ...
