    When a nearby star goes supernova, scientists will be ready

    Almost every night that the constellation Orion is visible, physicist Mark Vagins steps outside to peer at a reddish star at the right shoulder of the mythical figure. “You can see the color of Betelgeuse with the naked eye. It’s very striking, this red, red star,” he says. “It may not be in my lifetime, but one of these days, that star is going to explode.”

    With a radius about 900 times...

    Long-lasting mental health isn’t normal

    Abnormal is the new normal in mental health.

    A small, poorly understood segment of the population stays mentally healthy from age 11 to 38, a new study of New Zealanders finds. Everyone else encounters either temporary or long-lasting mental disorders.

    Only 171 of 988 participants, or 17 percent, experienced no anxiety disorders, depression or other mental ailments from late...

    See where Clinton and Trump stand on science

    Hillary Clinton’s “I believe in science” declaration aside, science has not played a starring role in the 2016 presidential election. Far from it. For the most part, the candidates’ science policies have trickled out in dribs and drabs, and in varying degrees of detail — talking points on a website here, a passing comment in response to a spur-of-the-moment question there.

    Yet science...

    The pressure is on to make metallic hydrogen

    In a few highly specialized laboratories, scientists bombard matter with the world’s most powerful electrical pulses or zap it with sophisticated lasers. Other labs squeeze heavy-duty diamonds together hard enough to crack them.

    All this is in pursuit of a priceless metal. It’s not gold, silver or platinum. The scientists’ quarry is hydrogen in its most elusive of forms.

    Several...

    The long road to detecting gravity waves

    The January e-mail from Syracuse University physicist Peter Saulson caught me off guard. It probably shouldn’t have, since I had been anticipating the news for 16 years, ever since I wrote Einstein’s Unfinished Symphony. The book chronicled the astrophysical community’s most cutting-edge start-up: gravity wave astronomy.

    Saulson’s message meant that Einstein’s symphony is no longer “...

    Analysis gives a glimpse of the extraordinary language of lying

    Dutch social psychologist Diederik Stapel was known for his meteoric rise, until he was known for his fall. His research on social interactions, which spanned topics from infidelity to selfishness to discrimination, frequently appeared in top-tier journals. But then in 2011, three junior researchers raised concerns that Stapel was fabricating data. Stapel’s institution, Tilburg University,...

    Discovery of neutrino mass earns 2015 physics Nobel

    The discovery that subatomic particles called neutrinos have mass has won Takaaki Kajita of the University of Tokyo and Arthur McDonald of Queen’s University in Kingston, Canada, the 2015 Nobel Prize in physics. The scientists led two sophisticated experiments that found that the elusive particles can morph from one variety into another — a phenomenon that can occur only if neutrinos have mass...

    Einstein's genius changed science's perception of gravity

    Albert Einstein opened humankind’s eyes to the universe.

    Before Einstein, space seemed featureless and changeless, as Isaac Newton had defined it two centuries earlier. And time, Newton declared, flowed at its own pace, oblivious to the clocks that measured it. But Einstein looked at space and time and saw a single dynamic stage — spacetime — on which matter and energy strutted,...

    Coffee reveals itself as an unlikely elixir

    For a historically mistrusted drink, coffee is proving to be a healthy addiction. Scientific findings in support of coffee’s nutritional attributes have been arriving at a steady drip since the 1980s, when Norwegian researchers reported that coffee seemed to fend off liver disease. Since then, the dark brown beverage has shown value against liver cancer, too, as well as type 2 diabetes, heart...

    How dollhouse crime scenes schooled 1940s cops

    View slideshow

    In November 1896, Lizzie Miller stumbled upon a shocking sight: The discolored body of her neighbor Maggie Wilson half-submerged in a bathtub, legs precariously dangling over the side. How did she die and who killed her?

    Wilson’s murder is fiction, though inspired by the work of an early 20th century British serial killer. The scene comes from the mind of self-taught...
