A new study provides evidence to support a simple measurement for diagnosing clinically significant airflow obstruction, the key characteristic of chronic obstructive pulmonary disease (COPD), the fourth leading cause of death in the United States. The study found that a 70% ratio of two indicators of lung function proved as or more accurate than other thresholds for predicting COPD-related hospitalizations and deaths.
A biological pathway previously found to contribute to the impact of stress on the risk of cardiovascular disease also may underlie the increased incidence of such disease experienced by individuals with lower socioeconomic status.
North Carolina State University researchers have developed the first portable technology that can test for cyanotoxins in water. The device can be used to detect four common types of cyanotoxins, including two for which the U.S. Environmental Protection Agency (EPA) recently finalized recreational water quality criteria.
Cyanotoxins are toxic substances produced by cyanobacteria. At high enough levels, cyanotoxins can cause health effects ranging from headache and vomiting to respiratory paralysis and death.
Condensation might ruin a wood coffee table or fog up glasses when entering a warm building on a winter day, but it's not all inconveniences; the condensation and evaporation cycle has important applications.
BLOOMINGTON, Ind. -- Psychologists at Indiana University who study how people pick their spouses have turned their attention to another important relationship: choosing a canine companion.
Their work, published in the journal Behavior Research Methods, recently found that, when it comes to puppy love, the heart doesn't always know what it wants.
The results are based upon data from a working animal shelter and could help improve the pet adoption process.
WASHINGTON, D.C., June 25, 2019 -- Biochips are essentially tiny laboratories designed to function inside living organisms, and they are driving next-generation DNA sequencing technologies. This powerful combination is capable of solving unique and important biological problems, such as single-cell, rare-cell or rare-molecule analysis, which next-generation sequencing can't do on its own.
Scientists using NASA's Hubble Space Telescope have confirmed the presence of electrically-charged molecules in space shaped like soccer balls, shedding light on the mysterious contents of the interstellar medium (ISM) - the gas and dust that fills interstellar space.
New Rochelle, NY, June 25, 2019--Researchers have shown that higher intelligence and younger age are predictors of greater cognitive recovery 2-5 years post-mild to severe traumatic brain injury (TBI). In contrast, injury severity, as measured by the duration of post-traumatic amnesia, was not associated with greater or worse long-term cognitive recovery, as supported by a study published in Journal of Neurotrauma, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
Columbia researchers have created a way to grow human hair in a dish, which could open up hair restoration surgery to more people, including women, and improve the way pharmaceutical companies search for new hair growth drugs.
It is the first time that human hair follicles have been entirely generated in a dish, without the need for implantation into skin.
Using 3D-Printing to Stop Hair Loss
For years it's been possible to grow mouse or rat hairs in the lab by culturing cells taken from the base of existing follicles.
Research into the hearts of zebrafish, a pet shop staple marked by their eponymous stripes, has shed light on ways the human heart muscle could be healed following damage.
A team of researchers led by Neil Chi, MD, PhD, professor of medicine at University of California San Diego School of Medicine, and Manuel Galvez-Santisteban, PhD, a postdoctoral scientist working alongside him, have pinpointed a signaling pathway in zebrafish heart cells that leads to the regeneration of damaged tissue. The findings are published in the June 25, 2019 issue of eLife.
Like a symphony, multiple brain regions work in concert to regulate the need to eat. University of Arizona researchers believe they have identified a symphony conductor - a brain region that regulates appetite suppression and activation - tucked within the amygdala, the brain's emotional hub.
The UA Department of Neuroscience team found the neurocircuitry controlling appetite loss, called anorexia, said assistant professor Haijiang Cai, who is a member of the BIO5 Institute and heads up the neuroscience lab that ran the study.
COLUMBUS, Ohio--A shortage of high school physics teachers has led to teachers with little-to-no physics training taking over physics classrooms, causing additional stress and job dissatisfaction for those teachers--and a difficult learning experience for their students.
But new research indicates that focused physics professional development for teachers--even those who have no prior physics training--can lead to better experiences for both students and teachers, and can improve students' understanding of physics concepts.
New Stanford linguistics research has analyzed how Republicans and Democrats use different language when discussing mass shootings on social media and found that Republicans talk more about the shooter and Democrats focus more on the victims.
If a man is handy with the vacuum cleaner, isn't averse to rustling up a lush family meal most nights after he's put on the washing machine having popped into the supermarket on his way home then it's more than likely his partner will have her own bank account.
A new study by Lancaster University reveals the way in which couples manage their money tells 'a tale of two marriages' in the UK today.
WASHINGTON--Women exposed to triclosan are more likely to develop osteoporosis, according to a study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
