A surgical procedure meant to counter ulcerative colitis, an immune disease affecting the colon, may trigger a second immune system attack, a new study shows.
People who start adulthood with a body mass index (BMI) in the normal range and move later in life to being overweight - but never obese - tend to live the longest, a new study suggests. Adults in this category lived longer than even those whose BMI stayed in the normal range throughout their life. Those who started adulthood as obese and continued to add weight had the highest mortality rate.
New drivers ages 15-25 cause nearly 1/2 of the 1 million+ road deaths worldwide. A new study in Risk Analysis suggests that driver ed programs use of fear-based messaging doesn't reduce risky driving and may even lead young drivers to take more chances.
The "second wave" of the coronavirus pandemic has placed much blame on a lack of appropriate safety measures. However, due to the impacts of weather, research suggests two outbreaks per year are inevitable. Though face masks, travel restrictions, and social distancing guidelines help slow the number of new infections in the short term, the lack of climate effects incorporated into epidemiological...
Results of a multi-centre, international, clinical trial co-led by Peter Munk Cardiac Centre (PMCC) cardiologist Dr. Dinesh Thavendiranathan point to the benefit of using a more sensitive test to detect heart function issues early, so cancer patients don't have to fight heart failure too.
A soft, flexible sensor system created with electrically conductive yarns could help map problematic pressure points in the socket of an amputee's prosthetic limb, researchers from North Carolina State University report in a new study.
Investigators demonstrate that image luminance has opposite effects on the contrast sensitivity of cortical pathways signaling lights than darks. It impairs luminance discrimination for the brightest stimuli of the scene while improving it for the darkest stimuli, a mechanism that is needed toefficiently sample natural scenes.
Despite an overall reduction in cigarette use over the last 20 years, nearly 1 in 5 boys (17.9%) and more than 1 in 10 girls (11.5%) around the world used tobacco at least once in the past month between 2010-2018, according to a new study published today in The Lancet Child & Adolescent Health journal.
An interim analysis of data from the phase 3 trial of the COVID-19 vaccine from Russia (Gam-COVID-Vac) suggests that a two-dose regimen of the adenovirus-based vaccine offers 91.6% efficacy against symptomatic COVID-19. The preliminary findings, published in The Lancet, are based on analysis of data from nearly 20,000 participants, three-quarters of whom received the vaccine and one quarter...
Researchers from USTC studied the morphological characteristics of precipitation areas over Tibetan Plateau and found that morphological characteristics of precipitation areas affects precipitation intensity.
The effect of the Covid-19 pandemic can be clearly felt in the marketplace. This has been an unprecedented existential crisis for individuals and organizations alike across the globe. To ensure communities and corporations emerge unscathed, leaders need to effectively respond to these trying times. The latest edition of the Frontiers of Business Research in China offers six practical perspectives...
The complex mechanics determining how galaxies spin, grow, cluster and die have been revealed following the release of all the data gathered during a massive seven-year Australian-led astronomy research project.
mRNA molecules from retrogenes are reverse transcribed to DNA and incorporated into the genome.
A new method for constructing special solar cells could significantly increase their efficiency. Not only are the cells made up of thin layers, they also consist of specifically arranged nanoblocks. This has been shown in a new study by an international research team led by the Martin Luther University Halle-Wittenberg (MLU), which was published in the scientific journal "Nano Letters".
Scripps Research scientists bring together multiple technologies to engineer potentially safer glucocorticoids, drugs used to treat COVID-19 and other conditions.
Microlaser particles have emerged as unique optical probes for single-cell tacking. However, due to inherent directionality of laser emission, cell tracking with laser particles suffers from frequent loss of cell traces. Recently, scientists in Harvard Medical School and Peking University placed omnidirectional visible laser particles into live cells, and demonstrated continuous spatial tracking...
Mark Schleiss, MD, pediatric infectious disease physician with the University of Minnesota Medical School and M Health Fairview, led a study that used improved techniques to show that the dried blood spot taken at birth can, in fact, find CMV infection in the newborn with almost 90% accuracy. The study was recently published in JAMA Pediatrics.
In the race to stop the spread of COVID-19, a three-layer cloth mask that fits well can effectively filter COVID particles, says a group of UBC researchers.After testing several different mask styles and 41 types of fabrics, they found that a mask consisting of two layers of low-thread-count quilting cotton plus a three-ply dried baby wipe filter was as effective as a commercial non-surgical mask...
A technique that delivers high-intensity focused ultrasound to targeted tissue under MRI guidance effectively treats intermediate-risk prostate cancer with minimal side effects, according to a new study.
Scientists at Scripps Research have clarified the workings of a mysterious protein called Gao, which is one of the most abundant proteins in the brain and, when mutated, causes severe movement disorders.
As the US confronts a bitter election season, political unrest and violence, a shaky economy, and a soaring death toll due to COVID-19, 84% of US adults say the country has serious societal issues that we need to address, according to a new poll.
The U.S. Preventive Services Task Force (USPSTF) recommends against screening for asymptomatic carotid artery stenosis in the general adult population. Carotid artery stenosis is the narrowing of arteries that supply blood to the brain. This recommendation applies to adults without a history of transient ischemic attack, stroke or other neurologic signs or symptoms related to the carotid...
An effort led by Lin Li, Ph.D., assistant professor of physics at The University of Texas at El Paso, in collaboration with students and faculty from Howard University, has identified key variants that help explain the differences between the viruses that cause COVID-19 and Severe Acute Respiratory Syndrome (SARS).
The Venus flytrap (Dionaea muscipula) is a carnivorous plant that encloses its prey using modified leaves as a trap. During this process, electrical signals known as action potentials trigger the closure of the leaf lobes. An interdisciplinary team of scientists has now shown that these electrical signals generate measurable magnetic fields.
A warmer global climate can cause mutations to have more severe consequences for the health of organisms through their detrimental effect on protein function. This may have major repercussions on organisms' ability to adapt to, and survive in, the altered habitats of the future. This is shown in a new Uppsala University research study now published in the scientific journal Proceedings of the...
