Astronomers have discovered powerful X-ray jets from two ancient supermassive black holes being illuminated by the afterglow of the Big Bang.

A researcher throws cold water on a recent effort that purported to eliminate black holes' greatest and most enduring mystery — the existence of their central singularity.

The following is a summary of “Performance of artificial intelligence-based models for epiretinal membrane diagnosis: A systematic review and meta-analysis,” published in the May 2025 issue of ...

In the world of black holes, there are generally three size categories: stellar-mass black holes (about five to 50 times the mass of the sun), supermassive black holes (millions to billions of ...

Besides particles like sterile neutrinos, axions and weakly interacting massive particles (WIMPs), a leading candidate for the cold dark matter of the universe are primordial black holes—black ...

Located in the stratosphere, the ozone layer blocks potentially harmful ultraviolet energy from reaching our planet's surface.

Background A consensus on an optical coherence tomography definition of lamellar macular hole (LMH) and similar conditions is needed. Methods The panel reviewed relevant peer-reviewed literature to ...

Lipid bilayers in mammalian membranes can have a more asymmetric composition than previously thought, new research shows. This lipid abundance asymmetry is enabled by the unique properties of ...

Trabeculectomy may contribute to the formation and progression of epiretinal membranes among glaucoma patients, a new study suggests.

Learn about epiretinal membranes. Discover the symptoms of these abnormal eye membranes and how they’re treated.

Pseudoholes are also caused by pulling, or traction, but the pull isn’t as strong as it is for a macular hole. Instead, pseudoholes happen when tissue called the epiretinal membrane pulls in ...

We see patients with epiretinal membranes every day, and the decision whether to operate or not is myriad. And I really congratulate the DRCR for taking the bulls by the horn.
