  • New study raises questions about cell phone safety

    Does heavy use of cell phones pose a risk of cancer? This question has provoked controversy for many years. A new study in rats now adds to those concerns. Its data linked long-term, intense exposure of the animals to radiation from cell phones with an increased risk of cancer in the brain and heart.

    The results have yet to be confirmed, the authors note. Moreover, they add, it’s not yet...

  • Famous physics cat now alive, dead and in two boxes at once

    Physicist Erwin Schrödinger’s cat can’t seem to catch a break. The fictitious feline is famous for being alive and dead at the same time, as long as it remains hidden inside a box. Scientists think about Schrödinger’s cat in this way so that they can study quantum mechanics. This is the science of the very small — and the way that matter behaves and interacts with energy. Now, in a new study,...

  • Possibility of strange new particle surprises physicists

    Last winter physicists detected hints of a potential new subatomic particle. It appeared to exceed their wildest dreams. Soon they may learn for sure if it exists at all. “I’m not aware of anybody who’d predicted the existence of such a particle,” says John Ellis. He’s a theoretical physicist in England at King’s College London.

    He likens the new data, he says, to “a dish on the table...

  • Feeling objects that aren't there

    Imagine this. You wake up in the morning to the irritating buzz of your alarm. Instead of fumbling for a snooze button, you wave your hand in the air in the general direction of the clock. There, in mid-air, you find it: an invisible button. It’s an illusion you can feel, like a hologram for your fingers. One swipe at the button, and the alarm shuts off. You’re free to sleep for a few more...

  • Less brilliant flowers still keep bees coming back

    Spring brings with it the sweet fragrance of fresh flowers and the buzzing of bumblebees. Those pollinators may seem to fly aimlessly as they search for the sugary liquid called nectar. But their flight plans actually do have a pattern. Flowers act as the insects’ air-traffic controllers. And new research shows that bees prefer flowers that aren’t too flashy.

    Flowers give bees clues...

  • News Brief: Why rainbows can lose some hues

    SAN FRANCISCO, Calif. — Some rainbows are missing a few colors. When the sun is low in the sky, those colorful arcs may contain only a fraction of the traditional red-to-violet hues. Or that’s what researchers reported December 17. They shared their new findings here at the American Geophysical Union’s fall meeting.

    Rainbows emerge as sunlight bends while passing through water droplets...

  • Some fish wear an invisibility cloak

    Fish that swim in the open ocean have nowhere to hide from hungry predators. But some may have evolved a kind of natural invisibility cloak that helps them hide in plain sight. Understanding how it works may let scientists and engineers develop new forms of ocean camouflage.

    Some species of fish have microscopic structures called platelets in their skin and scales. These platelets look...

  • Explainer: Locating a gun with sound waves

    Suppose that the boom of a gun is recorded by three microphones: Let's call them A, B and C. Assume that the three microphones are spaced 386 meters (1,266 feet) apart. That is the distance sound travels through air in one second. The boom reaches microphone A first. One second later it reaches microphone B. One second after that it reaches C. Draw a circle with a radius equal to 386 meters...

  • Boom! Sounding out the enemy

    After two years of fighting, the British soldiers stationed in France during World War I thought they had seen everything. This was the “Great War.” And it was different than any in the past. For the first time, there were tanks that rolled across farms, through barbed wire and over trenches. Airplanes were providing a new way to spy on the enemy. Poison gas was killing soldiers by the...

  • Light can control waves in heart tissue

    Researchers have found a new way to take charge of an out-of-control heart. All it takes is a light touch — literally touching the heart with a pulse of visible light.

    Your heart beats tens of thousands of times each day. Its pace may speed up or slow down as your activities change. Yet its rate remains fairly regular, thanks to electrical signals that travel as waves from cell to cell...
