Phys.org / Trouble swallowing? A nanogel tweak may keep therapeutic stem cells alive longer
Swallowing is a fundamental human function that supports nutrition and communication. Damage to swallowing muscles can reduce quality of life and even lead to aspiration pneumonia or malnutrition. Many patients suffer from ...
Phys.org / 3D-printed rattlesnake reveals how the rattle is a warning signal
A team of researchers from The University of Texas at El Paso has uncovered new evidence explaining why the rattlesnake's rattle—one of nature's most iconic warning signals—has persisted and proven so effective across ...
Phys.org / Simple 'cocktail' of amino acids dramatically boosts power of mRNA therapies and CRISPR gene editing
Lipid nanoparticles, or LNPs, best known as the delivery vehicle for the COVID-19 mRNA vaccines received by billions of people, are now at the center of a much larger medical revolution. Researchers are racing to use them ...
Phys.org / Biodegradable nanoparticles can seek and destroy diseased immune cells
Johns Hopkins Medicine scientists say they have developed a simplified version of biodegradable nanoparticles that can "educate" the immune system to find and destroy disease-causing cells throughout the body. The study, ...
Phys.org / What primate faces reveal about empathy: Humans mirror emotions across species
Humans perceive emotional expressions displayed by non-human primates and spontaneously mimic these expressions, according to a study published in the open-access journal PLOS One by Ursula Hess from Humboldt University of ...
Phys.org / Flash heating upcycles waste glass into SiC nanowires in seconds
Engineering silicon carbide (SiC) with tailored morphologies for electronics and structural reinforcement materials has always been a costly and time-consuming affair, but scientists can now do it in a flash. A new study ...
Phys.org / Scalable quantum batteries can charge faster than their classical counterparts
Over the past decades, energy engineers have developed increasingly advanced battery technologies that can store more energy, charge faster and maintain their performance for longer. In recent years, some researchers have ...
Phys.org / Still standing but mostly dead: Recovery of dying coral reef in Moorea stalls
In April 2019, a marine heat wave struck a coral reef on the island of Moorea in French Polynesia, killing much of the coral and the beneficial algae that colonized it. This "bleaching" event reduced live coral populations ...
Phys.org / Racial/ethnic disparities among people fatally shot by U.S. police vary across state lines
In a new analysis, racial and ethnic disparities in fatal shootings of U.S. residents by police varied widely between states. Roland Neil of the RAND Corporation in California, U.S., and colleagues present these findings ...
Phys.org / Childcare burden may explain US gender gap in poverty rates
Gender differences in poverty rates in the United States may be associated with women's differing circumstances—particularly the burden of dependent children—rather than inherent to gender itself, according to a study ...
Phys.org / News media representations contribute to stigma around childlessness, study finds
The news media is shaping reproductive narratives and stigma around childlessness, presenting it as a threat to national interests, a deviation from moral or cultural norms, as a risk and, sometimes, as a legitimate life ...
Phys.org / Hydrogen atmosphere could keep exomoons habitable for billions of years
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck ...
