    There are added benefits to methotrexate and etanercept for rheumatoid arthritis patients, such as myself. After a recent major flare-up, my rheumatologist put me on that therapy. Many people don’t realize that along with inflammation and pain, arthritis also brings major fatigue and lack of sleep because of pain. I feel much better now, and […]

    I can think of a place other than the moon where NASA could develop a closed life-support system for staging rehearsals of manned Mars exploration. Why not Earth? Advantages would include a protective atmosphere, a day length closer to the Martian sol, bone-and-muscle-friendly gravity, and easy access to mechanical and medical resources. The cost would […]

    Your article quotes a pediatrician as saying, “we’re moving to selection on the basis of a trait that is of no benefit to the child to be born.” I disagree. The child to be born would have the benefit of a healthy older sibling. Even saving the parents from the trauma of a dying child […]

    I know some people who carefully shield their bodies from the sun with sunscreen and clothing, and their skin is extremely pale. But if tanning acts as a protector, is it actually safer to maintain a “healthy” tan? Chris EsseBeverly Hills, Calif. Scientists continue to debate this question vigorously.

    I would guess that a rock measuring 1 kilometer across, landing near New Zealand 500 years ago, would have done much more than create a tsunami 300 to 500 feet high. Was the object 1 km across before encountering Earth’s atmosphere? Don ArthurNorth Coventry, Pa. Yes. The object’s estimated size is before it hit the […]

    Perhaps Stefan Koelsch’s study should have been limited to trained musicians, rather than exclude them. Word and visual associations in music are vigorously reinforced in movie soundtracks, cartoons, and elsewhere. But classical composers and musicians typically take pains to isolate their musicianship from any and all nonmusical elements. This inquiry may shine light on the […]

    The observations in this article are of stars and galaxies billions of light-years away and billions of years old. Has anyone ever thought about what the universe out there looks like today? Earl RosenwinkelDuluth, Minn. People have thought about what the universe looks like now and what it will look like in the distant future, […]
