Phys.org / Simplifying clean hydrogen production with a new all-in-one photocatalytic cocatalyst
Researchers have demonstrated the first "all-in-one" cocatalyst for photocatalytic overall water splitting, a breakthrough that could simplify the production of clean hydrogen fuel. The discovery marks an important step toward ...
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 / 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 / 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 / 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 / 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 / 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 / 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 ...
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 / One blue whale song unlocks oceans of data
Trying to find a whale song in the ocean is like trying to find a needle in a haystack. But now, UNSW Sydney researchers say they've trained a model, with just a single case study, to find blue whale songs in recordings that ...
Phys.org / Genomic tool untangles how microbes spread—even when they look almost identical
Researchers have developed a powerful new tool that can track how microbes spread between people with unprecedented precision, offering new ways to prevent infections and improve treatments in the future. The research, published ...
Phys.org / Extra sets of chromosomes may help aggressive tumor cells spread, study finds
One of the biggest challenges in cancer research is understanding why some tumor cells become especially aggressive, invasive and resistant to treatment. Scientists have increasingly linked these dangerous traits to polyploid ...
