Brightness changes in coronal loops may predict solar flares Study improves forecasting with 60–80% accuracy 2–6 hours before events Findings could protect space missions and terrestrial technologies ...

Cataract surgery is one of the oldest surgical procedures known, first documented in the fifth century BC. [12] In ancient times, cataracts were treated with a technique called couching, which ...

Two coronal mass ejections (CMEs) struck Earth’s magnetic field, causing geomagnetic storms that reached G3 levels on January 1. An X1.1-class solar flare on December 29, 2024, caused strong ...

Two giant holes in the Sun could create impactful space weather for Earth in early February. Recent NOAA satellite images show two coronal holes, areas on the surface of the Sun devoid of plasma.

Cataracts can develop in children due to congenital factors, trauma, infections, or steroid use, leading to blurry vision. Early identification of symptoms such as white pupil discoloration ...

A YAG laser posterior capsulotomy is a procedure performed to treat cloudy vision that may remain after undergoing cataract eye surgery. A cataract is a clouding or opacification of the human lens of ...

Appearing as cooler, dark patches when viewed in extreme ultraviolet and soft X-ray images of the sun, coronal holes are caused when the local magnetic field opens up, allowing the solar wind to ...

Joan and Irwin Jacobs Retina Center at Department of Ophthalmology, Shiley Eye Center, University of California San Diego, La Jolla, California, USA Aim: To describe vitreoretinal imaging of eyes with ...

focused on coronal loops. These loops are arch-like structures in the Sun’s corona. The team studied loops near strong solar flares. They observed how the brightness of these loops fluctuated ...

The ranking features a focused list for each of five select procedures: knee surgery & knee replacement, hip surgery & hip replacement, shoulder surgery, refractive eye surgery, and cataract surgery.
