Unlocking RNA functionality: A redox-responsive approach
Chemists have developed a strategy using disulfide-containing small molecules to facilitate the reversible control and delivery of ribonucleic acid (RNA). A research team has developed a method that takes advantage of a chemical process called post-syn…
A new study reveals that marine cyanobacteria communicate
A breakthrough study changes the way we understand cyanobacteria, which are essential for the sustenance of life. The study shows that these organisms do not operate in isolation, but rather physically interact through membrane-nanotubes, which functio…
Newly developed material logs and stores stress information of infrastructure
A new material may be the key to quickly flag damaged infrastructure. This material offers a way to reduce the manpower required to regularly monitor structures that undergo daily use such as bridges. Compared to previous methods, this environmentally …
Liquid metal-based electronic logic device that mimics intelligent prey-capture mechanism of Venus flytrap
A research team has developed a liquid metal-based electronic logic device that mimics the intelligent prey-capture mechanism of Venus flytraps. Exhibiting memory and counting properties, the device can intelligently respond to various stimulus sequenc…
Nanoparticles: Risk for babies in the womb
Little is yet known about the health effects of nanoparticles on pregnancy. An interdisciplinary team is currently analyzing the risks for babies in the womb. Using a lab model, the researchers were able to determine that certain nanoparticles impair t…
Women with excess weight as a teen or young adult may have higher stroke risk by age 55
Women with excess weight at age 14 or 31 may have increased ischemic (clot caused) stroke risk before age 55. The same ischemic stroke risk was not found in men. Losing excess weight after adolescence may not eliminate the stroke risk.
New glioblastoma treatment reaches human brain tumor and helps immune cells recognize cancer cells
In a major advance for the treatment of the deadly brain cancer glioblastoma, scientists used ultrasound technology to penetrate the blood-brain barrier and provide a small dose of a chemotherapy and immunotherapy drug cocktail. The study found that th…
Searchable database for Alzheimer’s research
A searchable database is now ready to help study Alzheimer’s disease. Neuroscience and biomedical informatics researchers have created the comprehensive, user-friendly repository.
Using oceanography to understand fronts and cyclones on Jupiter
New research led by Lia Siegelman, a physical oceanographer at UC San Diego’s Scripps Institution of Oceanography, shows that the roiling storms at the planet Jupiter’s polar regions are powered by processes known to physicists studying Earth’s oceans …
Lifesaving childbirth blood loss intervention is highly cost-effective
A lifesaving package including early detection and bundled treatment for women who have heavy bleeding during childbirth has been found to incur minimal additional cost according to new analysis from 78 hospitals around the world.
Hidden challenges of tooth loss and dentures revealed in new study
A new study has revealed the hidden emotional challenges patients go through following tooth loss. Patients highlight feelings of self-consciousness, shame or fear as well as physical sensations such as pain and sensitivity and worries about how tooth …
How medical models can transform agriculture
Researchers use lessons from nanomedicine and digital twin technologies to address food insecurity and climate change.
Better farming through nanotechnology
Advanced technologies enable the controlled release of medicine to specific cells in the body. Scientists argue these same technologies must be applied to agriculture if growers are to meet increasing global food demands.
Macrophages behave like mural cells to promote healing of ischemic muscle injury
Innate immune cells including macrophages and neutrophils have unique properties that allows them to quickly accumulate in large numbers at the site of infection or injury. A new study establishes that macrophage in the adult ischemic muscle induce a p…
First-of-its-kind test can predict dementia up to nine years before diagnosis
Researchers have developed a new method for predicting dementia with over 80% accuracy and up to nine years before a diagnosis. The new method provides a more accurate way to predict dementia than memory tests or measurements of brain shrinkage, two co…
Climate policy: competing crises
Current crises are distracting from the climate crisis and weakening support for climate action, a Europe-wide survey reveals.
Vigorous exercise may preserve cognition in high-risk patients with hypertension
People with high blood pressure have a higher risk of cognitive impairment, including dementia, but a new study suggests that engaging in vigorous physical activity more than once a week can lower that risk.
Younger children in school year are more commonly diagnosed with ADHD than their older classmates, says new study
New research has found that teachers may be attributing signs of age-related immaturity in children, to conditions such as Attention-Deficit/Hyperactivity Disorder (ADHD) or Autism Spectrum Disorder (ASD). The results of the study showed that the young…
Severity of calls to US poison centers increases sharply for both adults, kids
The number of calls about intentional exposures, such as illegal drug overdoses, that resulted in death among adults increased a whopping 233.9% between the beginning of 2007 and the end of 2021. And that’s just one of several troubling poisoning trends.
