A research chemist applied his analytical smarts to his son's eye cancer. By analyzing family photos starting with some taken just a few days after birth, the dad found that signs of retinoblastoma, a rare eye cancer, could be detected quite early.

Cut a tumor from a child's brain and you may save a life. But surgery can hurt the child if healthy brain cells are removed. A Seattle doctor is working on a substance that might help. It binds tightly to cancer cells and makes them glow, so they're easier to distinguish from healthy tissue.

NASA's Lunar Atmosphere and Dust Environment Explorer is on its way to the Moon. It lifted off on time Friday night from NASA's Wallops Flight Facility in Virginia. Some early software problems have been successfully resolved.

A satellite is scheduled to take off for the Moon Friday — carrying an instrument that could represent the future of deep space communication. Instead of sending data back to earth using radio waves, the Lunar Laser Communications Demonstration will use pulsed light waves.

Scientists aren't sure exactly why holes form in the hot and glowing outermost layer of gas surrounding the sun. But one theory is that the dark blotches we see on images of the sun could be the remnants of the (relatively) cool splotches called sunspots.

Images that evoke a phobic reaction to holes have unique characteristics in terms of contrast and fine detail. Researchers found they were similar in some respects to features of venomous animals.

Late summer tends to be a slow month for news. But at All Things Considered, we put on a two hour program, no matter what. So — without a trace of irony — one of our science correspondents offered to help fill some holes in the show with a series of stories about holes. Today he looks at how the brain copes with the ambiguity of "the hole idea," and "the whole idea."

Late summer tends to be a slow month for news. But at All Things Considered, we put on a two hour program, no matter what. So — without a trace of irony — one of our science correspondents offered to help fill some holes in the show with a series of stories about holes. Today, he explores the complex philosophical question, what is a hole? And when is a hole not a hole?

Smart windows change how much sunlight they let through on a hot day. Such windows could reduce the demand for energy by reducing the need for air conditioning. This quest has been going on for years but it's got years to go before the project becomes a reality.

What happens when you drop a ball down a hole drilled through the center of the Earth? The answer might surprise you.

Late summer tends to be a slow month for news. But at All Things Considered, we put on a two hour program, no matter what. So — without a trace of irony — one of our science correspondents offered to help fill some holes in the show with a series of stories about holes. In this edition: Black holes.

One year ago, NASA's Curiosity rover landed on Mars. We look at the science the mission has accomplished and the strange gravity anomaly engineers stumbled onto at the bottom of Gale Crater, where the rover landed.

In its first year on the red planet, the six-wheeled rover has driven a little bit more than a mile, drilled into rocks and performed chemical and mineral analysis. Its next journey is a 5-mile trek to the foothills of Mount Sharp to help study Mars' watery past.

For bakers, turning a donut into a donut hole is simple. For a mathematician, it's impossible.

On July 19, a spacecraft nearly 900 million miles from Earth took a color picture of our planet. NASA's Cassini spacecraft snapped the picture from orbit around Saturn. Now scientists have finished processing the picture. It shows a small blue dot next to the giant ringer planet.

This doesn't look like your trusty potato battery: a prototype device made by scientists at the University of Maryland uses wood fibers coated with carbon nanotubes to create an electric current.

A technology called adaptive optics is enabling astronomers to peer into space as never before. The specialized telescopes, which have mirrors that can adjust their shapes up to 1,000 times per second, compensate for the blurring that happens when light passes through Earth's atmosphere.

After 10 weeks, hypertensive rats fed a diet consisting of 5 percent asparagus had lower blood pressure than their counterparts fed a standard rat diet.

Nothing lives forever, but bryophytes come close. Scientists have found a kind of plant in the Canadian Arctic that started growing again after being buried under a glacier for 400 years.
Monday, May 27, 2013
Underneath a receding glacier in the Canadian Arctic, researchers found something surprising: a kind of plant related to moss that was not only still green, but also growing.
