Phys.org / Re-engineered human cells boost gene-editing particle potency across multiple delivery systems
Gene editing has emerged as a powerful approach for targeting the genetic causes of disease, but getting the editing machinery into the right cells efficiently, safely, and at the scale needed for therapies remains one of ...
Phys.org / Sombrero Galaxy's vast halo emerges in rare detail 30 million light-years away
Messier 104, nicknamed the Sombrero Galaxy, is a popular target for amateur observing and astronomical research. Its recognizable extended halo, as well as a faint stellar stream, are captured in exquisite detail in this ...
Phys.org / Light near surface of ultra-thin optical fibers can sort twisted nanoparticles
Many important objects in the world can be divided into two categories based on their chirality or handedness, including molecules important for life such as amino acids. Such chiral objects (formally defined as objects which ...
Phys.org / Bipartisan-cited science is rarely used by policymakers, study finds
Past research has shown that even though science is commonly viewed as essential for effective policymaking, Democrats and Republicans cite different scientific research when creating policy—even when addressing the same ...
Phys.org / This battered Jurassic sea giant held on against the odds, and its fossil hints at an unexpected survival strategy
A fossil discovery in Mistelgau, Northern Bavaria, Germany, reveals that the last representatives of the giant ichthyosaurs of the genus Temnodontosaurus survived longer in the Southwest German Basin than previously thought. ...
Phys.org / Chromosomes condense in three timed chemical waves during cell division, study shows
DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes. These histones carry numerous chemical modifications that act as molecular signals, controlling ...
Phys.org / A mother's gift: Plastid-derived structures help sea urchin development and dispersal
During the development of marine organisms—from fertilization through to juvenile stages—it is often observed that the eggs released into the water column are initially supplied with only a small fraction of the energy they ...
Phys.org / Human-altered estuaries now drive stronger tides farther inland
A study led by Wageningen University & Research shows that human interventions have significantly changed tides in river estuaries over the past centuries. In many regions around the world, the difference between high and ...
Phys.org / Machine learning identifies catalyst 'sweet spot' for greener urea from waste gases
Urea is an extremely important chemical, especially for fertilizers. But, making urea is energy intensive and relies heavily on fossil fuels. However, new findings from Griffith University and the Queensland University of ...
Phys.org / Why delaying climate action now means higher seas by 2100
Imagine your favorite sunny beach. Anywhere will do. You look out and see the ocean stretching to the horizon. To a glaciologist, that view is not just water; it's melted ice. Our new study shows that the best case sea-level ...
Phys.org / One-way phonon synchronization could survive noise and defects, theoretical physicists suggest
A novel approach for realizing the one-way quantum synchronization of phonons has been proposed by three theoretical physicists at RIKEN. Importantly, this method is remarkably resilient against practical challenges such ...
Phys.org / Promising H5N1 vaccine protects dairy calves and mice against severe disease
Researchers at the University of Nebraska–Lincoln have developed a vaccine approach that shows promise in protecting against highly pathogenic bird flu, demonstrating strong efficacy in both mice and cattle. Avian influenza ...
