Virtual laboratory predicts train vibrations

The construction of new rail lines, or the relocation of old ones underground, has increased society’s interest over recent years in the vibrations produced by trains, especially among people who live or work near the tracks. Now a study headed …

Advance could change modern electronics

CORVALLIS, Ore. — Researchers at Oregon State University have solved a quest in fundamental material science that has eluded scientists since the 1960s, and could form the basis of a new approach to electronics.

Berkeley Lab Physicist Challenges Speed of Gravity Claim

Albert Einstein may have been right that gravity travels at the same speed as light but, contrary to a claim made earlier this year, the theory has not yet been proven. A scientist at Lawrence Berkeley National Laboratory (Berkeley Lab) says the announcement by two scientists, widely reported this past January, about the speed of gravity was wrong.Stuart Samuel, a participating scientist with the Theory Group of Berkeley Lab’s Physics Division, in a paper published in Physical Review Letters, has demonstrated that an “ill-advised” assumption made in the earlier claim led to an unwarranted conclusion.
