Why pollution affects some asthma patients more than others
For many people with asthma, air-quality advisories are harbingers of worsening symptoms. But for reasons science has struggled to explain, the extent to which pollution exacerbates asthma varies widely from person to person.
Robust colorectal cancer signature identified in large-scale microbiome study
Researchers have long suspected that the gut microbiome—the community of bacteria and other microorganisms living in the intestine—is closely linked to colorectal cancer. In a new study published in Cell Host & Microbe, an international group of researchers from the Mi-EOCRC cons
Animal vs. plant protein: How beef and pea diets reshaped IBD severity in mice
New research sheds light on why red meat may worsen inflammatory bowel disease (IBD)—and how other protein sources could help protect the gut.
Bandage-like device delivers hydrogen sulfide to wounds, boosting blood flow where healing
For most people, a blister or small cut is an inconvenience. For others, it can become something much more serious. O recorte ajuda a contextualizar a pauta dentro de Fitness.
Remaking the past: How memory works
Imagine you're 6 years old and in the back seat of your parents' car on a road trip. Your mum decides to stop for breakfast food at lunchtime and pulls into a quiet roadhouse where other travelers eat apple pie and drink cola with a scoop of vanilla ice cream on top.
Vulnerable ALS neurons reveal molecular warning signs before cell death begins
A new study from the Knight Initiative for Brain Resilience researchers may help explain an enduring mystery about amyotrophic lateral sclerosis (ALS): why the disease kills off some of the brain and spinal cord's movement-controlling neurons while others show greater resilience.
Medicaid expansion boosted coverage for indigenous communities, research finds
American Indian and Alaska Native populations continue to experience higher rates of uninsurance and chronic disease than many other groups in the United States. Now, new research led by the University at Albany examines how different provisions of the Affordable Care Act affecte
Can we engineer being on the same wavelength with others? Research offers a cautious 'yes'
We often feel that we are "on the same wavelength" with one another, but can science identify and engineer this phenomenon? Studies by a team of neuroscience researchers suggest that it's possible—a connectivity that is both beneficial and can be enhanced for therapeutic and othe
New tool helps uncover rare genetic mutations in common diseases, including Parkinson's
Studies of genetics conducted in yeast cells, human neurons, mice or other model systems often reveal networks of genes that could contribute to complex diseases, such as breast cancer, type 2 diabetes and Parkinson's disease. But those findings don't always translate to human bi
Blood vessel cells keep fixed signaling roles for weeks, reshaping view of capillary commu
The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood flow, sense physical forces and keep vessel walls intact. Scientists have known about this signaling for decades. What they didn't know, until now, is that
Hospital discharge sedatives linked to more falls, readmissions and deaths in older adults
Older adults discharged from hospital with a new prescription for a sedative, especially a benzodiazepine or antipsychotic, are at increased risk of falls and other negative consequences, according to new research published in the Canadian Medical Association Journal.
