Medical Xpress / Rising temperatures linked to higher risk of homicide and suicide in Mexico and Brazil
As temperatures on Earth continue to rise, some researchers have been trying to understand how climate change influences people's physical and mental health. Some past studies have found an association between warmer weather ...
Medical Xpress / Ketamine triggers morning cortisol surge tied to fewer suicidal thoughts—but the link remains uncertain
In 1970, ketamine was approved as an anesthetic. It works by blocking receptors in the brain. Suicidal tendencies are among the dangers that accompany severe depression. Doctors have found that a low dose of ketamine, much ...
Phys.org / A $10 soil test goes global with virtual reality training for farmers
Last year, we described Agrilo, an affordable "colorimetric" soil-testing system developed through research at MacEwan University. Using a smartphone camera to interpret color changes, Agrilo measures soil nutrients and can ...
Phys.org / Engineered enzymes forge carbon-carbon and carbon-nitrogen bonds with high selectivity
Researchers from the Manchester Institute of Biotechnology, including Dr. Zachary Birch-Price and professor Anthony Green, have developed a new family of engineered enzymes that can create several different types of chemical ...
Phys.org / Decoding smell: Study reveals how wind transforms odor signals
Humans trust dogs to help find missing people, and bees to pollinate their crops. But scientists still don't fully understand how these animals use their extraordinary sense of smell to locate the source of an odor.
Medical Xpress / Cells' own abnormal RNA may trigger inflammation during viral infection, challenging 20 years of assumptions
New research led by the Hudson Institute of Medical Research has shown how a cell recognizes that it is infected with a virus to protect itself and surrounding cells or induce inflammation. The discovery, published in Nature ...
Medical Xpress / MRI model reveals microstructural brain changes linked to Huntington's disease
Researchers have shown that an imaging model can detect microstructural abnormalities in the brain associated with Huntington's disease, potentially offering a new method for monitoring disease progression and evaluating ...
Phys.org / Skies darken as solar eclipse heads south from Arctic to Spain
One of nature's greatest spectacles—a rare total solar eclipse—cast its shadow on Wednesday, briefly turning day into night in Russia's remote Arctic north and western Iceland before heading toward mainland Europe.
Phys.org / Songbirds may have developed sharper senses to de-husk seeds
Songbirds, birds belonging to the Passeriformes order, are best known for their ability to produce complex musical sounds. Yet some songbird species also have another remarkable skill: They can easily remove the tough layer ...
Medical Xpress / Scientists uncover drivers of recurrent arthritis after immunotherapy, suggesting potential biomarkers
A new study led by researchers at The University of Texas MD Anderson Cancer Center has shown that inflammatory arthritis occurring as a side effect of immune checkpoint inhibitors behaves like an immune-memory disease, suggesting ...
Medical Xpress / Simple blood test on a chip could help diagnose lung cancer
Researchers at Tel Aviv University have developed a new method for diagnosing lung cancer: a simple, fast, low-cost blood test that does not require DNA sequencing. The method identifies a chemical fingerprint of cancer cells ...
Phys.org / Review of studies on single-use plastics reveals broader circular economy approach is needed
A review of research published in the Interdisciplinary Environmental Review on single-use plastics argues that tackling the waste problem will require a shift from recycling alone to a broader circular economy approach, ...
