A major risk of breast cancer screening may have been overestimated for decades

A comprehensive reanalysis of eight major randomized screening trials suggests that breast cancer overdiagnosis rates from mammography may be below 5%, significantly lower than previous estimates of 30% to 50% that have fueled debate over screening guidelines.

A black hole jet is aimed at us … and it's in our galaxy

Astronomers have identified the first microblazar within our own galaxy, located roughly 12,000 light-years away—a black hole system whose relativistic jet happens to be pointed directly toward Earth. Read more: A black hole jet is aimed at us … and it's in our galaxy

That fresh cleaning smell could be filling your home with nanoparticles

Research has found that common scented cleaning products can react with indoor ozone to produce billions or trillions of nanoparticles within minutes, potentially delivering an inhaled dose comparable to or exceeding that from heavy traffic exposure.

OSIRIS-REx Sample Analysis Reveals Asteroid Bennu's Fiery and Icy Origins

NASA's OSIRIS-REx mission, which successfully returned samples from asteroid Bennu in 2023, continues to yield insights into the early solar system. Scientists analyzing the collected material have discovered that Bennu's composition reflects a complex formation history involving both fiery and icy conditions. The samples contain minerals

Direct Oral Anticoagulants Show Significant Stroke Prevention Benefit in Atrial Fibrillation Patients

Study Highlights Potential for Wider Anticoagulant Use Patients with atrial fibrillation face an elevated risk of stroke, and managing this risk often involves anticoagulant medications. A new randomized clinical trial called SINGLE-AF has now provided robust evidence supporting the use of direct oral anticoagulants (DOACs) in a patient population that

CRISPR Gene Therapy Shows Durable Cholesterol Reduction in Phase 2 Trial

Experimental CRISPR Therapy Achieves Year-Long Cholesterol Reduction A single injection of an experimental CRISPR gene-editing therapy has produced substantial and lasting reductions in "bad" cholesterol (LDL) and triglycerides in patients with challenging-to-treat lipid disorders. The findings come from a Phase 2 clinical trial, where researchers observed that a
