Medical Xpress / Congenital aniridia causes a progressive loss of corneal sensitivity, clinical study reveals

Congenital aniridia is a rare disease caused, in most cases, by mutations in the PAX6 gene, which is essential for the development of ocular structures. Although the most visible feature is the total or partial absence of ...

Phys.org / Energy loss triggers quantum thermal Hall-like effect at macroscopic scale

In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are essentially quantized energy ...

Phys.org / Russian astronomers observe the eruptive behavior of a young star

Russian astronomers from Moscow State University have performed photometric, polarimetric, and spectroscopic observations of a young star designated IRAS 21204+4913. Results of the new observations, which were published February ...

Phys.org / A cosmic explosion with the force of a billion suns went unseen—until we caught its echo

Some of the universe's most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front plows into its surrounding ...

Medical Xpress / A potential immunotherapy strategy for early-stage prostate cancer

Immunotherapy has been generally ineffective for prostate cancer because the tumors are considered immunologically "cold," meaning they do not attract enough immune cells to mount a strong attack. Hormone therapy commonly ...

Phys.org / Using high-energy sparks to degrade pollutants without generating waste

A study published in the Chemical Engineering Journal proposes a new approach to environmental remediation of pharmaceutical pollutants in water flows. This approach is based on a phenomenon known as "sparks," which refers ...

Phys.org / Exceptionally preserved 551-million-year-old site suggests Avalon biota lasted longer

Researchers studying the soft-bodied Ediacaran biotas of the world generally accept that there are three distinct assemblages. The 575–560-million-year-old (Ma) Avalon Assemblage is best known from the Ediacaran of Newfoundland, ...

Phys.org / Matching vibrations is all it takes to shut down superconductivity in a nearby crystal

The world is never really at rest. Even in a vacuum near ultracold temperatures where all classical motion should come to a halt, you'll find quantum fluctuations. In thin, two-dimensional materials, these include random ...

Phys.org / Green turtle nests may bury 'plastic rocks' and endanger the species

Even the most remote regions of the globe are not free from plastic pollution. In a study published in Marine Pollution Bulletin, researchers from São Paulo State University (UNESP) in Brazil have detected plastic rocks ...

Tech Xplore / 'Solar battery' stores sunlight for days, then releases hydrogen on demand

A new material can store energy from sunlight and convert it into hydrogen days later. The material, jointly developed by researchers from Ulm and Jena, can do this even in the dark. The process is reversible and can be reactivated ...

Phys.org / Carbon-based catalyst can use sunlight to degrade PFAS

An international team of scientists led by the University of Bath has developed a new catalyst—a substance that speeds up chemical reactions—that uses sunlight to break down so-called "forever chemicals" prevalent in ...
