Saturday, January 04, 2014

Students at Rice University in Houston are finding low-cost solutions to big global health problems. The women running the program are hoping to get these young engineers hooked on helping. One particularly successful device that helps infants breathe has already been tested in Malawi and will be distributed to hospitals around the country.


How Pictures Of Infant Boy's Eyes Helped Diagnose Cancer

Wednesday, November 06, 2013

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.


Why Painting Tumors Could Make Brain Surgeons Better

Thursday, September 12, 2013

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.

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.


Coronal Holes: The (Rarely Round) Gaps In The Sun's Atmosphere

Thursday, September 05, 2013

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.


The Inside Story On The Fear Of Holes

Hole Or Whole, Why Can Our Brains Hear The Difference?

Tuesday, August 27, 2013

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."


Defining A Hole Presents A Philosophical Quandry

Wednesday, August 21, 2013

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?


Scientists Reach Milestone In Quest For Smart Windows

Thursday, August 15, 2013
