Here's a summary of today's top science stories.

Gut Bacterium and Colon Cancer Breakthrough

Scientists have identified how a bacterial toxin associated with colorectal cancer damages the colon by binding to a receptor called claudin-4, and designed a decoy protein that successfully blocked the toxin in mice, offering a potential new therapeutic approach.

Webb Telescope Uncovers Hidden Exoplanet

NASA's James Webb Space Telescope has discovered a previously hidden planet within a well-known star system, showcasing the telescope's advanced capabilities for detecting exoplanets beyond the reach of earlier observatories.

Meteorite Contains Amino Acids

A meteorite that struck a New Jersey home in 2024 has been found to contain amino acids, potentially offering insights into how the building blocks of life arrived on early Earth.

Artemis III Moon Landing Preparations

NASA is planning an Artemis III demonstration mission in 2027 to practice rendezvous and docking operations between commercial human landing systems and the Orion spacecraft, paving the way for the actual crewed Moon landing targeted for 2028.

Perseverance Rover Studies Martian Impact History

NASA's Perseverance rover has been analyzing geological data on Mars to read the record of ancient impacts that shaped the planet's surface, providing insights into the Red Planet's early history.

SpaceX Prepares Starship Flight 13 Test

SpaceX is preparing for the critical Flight 13 test of Starship, the world's largest rocket, with plans to deploy Starlink V3 satellites during the mission.

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
