Phys.org / Natural-language AI helps chemists design molecules step by step
Designing molecules is one of chemistry's most complex challenges. From life-saving drugs to advanced materials, each compound requires a precise sequence of reactions. Planning these steps demands both technical knowledge ...
Phys.org / Self-regulating process governs cosmic order inside star clusters
A team of astrophysicists from Nanjing University and University of Bonn have demonstrated that, rather than being random, the mass of new stars born inside a star cluster is actually governed by a defined process of self-regulation. ...
Phys.org / Orbital dances unlock true masses of Orion's young stars
A star's mass determines its entire life story, from how it shines to how it dies. For young stars shrouded in dust, getting an accurate mass has long been difficult, but new radio measurements are beginning to change that. ...
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 / Gravity's subtle effect on light could improve groundwater, volcano and carbon storage monitoring
A study by University of Wollongong (UOW) physicist Dr. Enbang Li has demonstrated that gravity can subtly influence the behavior of light, a breakthrough that could underpin future technologies for monitoring groundwater, ...
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 / 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 / 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 / How electron structure affects light responses in moiré materials
In materials science, if you can understand the "texture" of a material—how its internal patterns form and shift—you can begin to design how it behaves. That's the focus of the work of Zhenglu Li, assistant professor in the ...
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 / 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 / Some rays flash decoy eyes while others never do, as evolution's hidden trade-off comes into focus
From butterflies to peacocks, bold circular "eyespots" are among nature's most eye-catching patterns. But why do they appear in some animals and not others? A new study of skates and rays finally provides an answer—and it ...
