The World Health Organization is holding a special meeting in Geneva, Switzerland, to discuss how to fast-track the development of experimental therapies and vaccines to combat the Ebola outbreak.


The Latest Word From WHO On Experimental Ebola Therapies

Friday, September 05, 2014

Vaccinations and therapeutics are being tested. Some could be available for use as early as November, if they prove to be safe.


How Much Bigger Is The Ebola Outbreak Than Official Reports Show?

Thursday, August 21, 2014

A Virtual Outbreak Offers Hints Of Ebola's Future

Thursday, August 14, 2014

As the Ebola outbreak rages in West Africa, it is also unfolding — in a virtual sense — inside the computers of scientists trying to predict how far the outbreak will spread and when it will end.


Biologists Choose Sides In Safety Debate Over Lab-Made Pathogens

Wednesday, August 13, 2014

The debate about whether it's OK to engineer and study microbes that could prompt a human pandemic has reignited. Each side now has a website and its own list of Nobelists and superstar supporters.


Ethics Panel Endorses The Use Of Experimental Drugs To Slow Ebola

Tuesday, August 12, 2014

A panel convened by the World Health Organization has approved the use of experimental drugs and vaccines to combat the Ebola outbreak, so long as certain conditions are met.

Big Data Peeps At Your Medical Records To Find Drug Problems

Monday, July 21, 2014

It's been tough to identify the problems that only turn up after medicines are on the market. An experimental project is now combing through data to get earlier, more accurate warnings.


The Little Spacecraft That Couldn't

Thursday, July 10, 2014

A team of volunteer space cowboys may have to say goodbye to ISEE-3 and to their dream of reviving for a final mission the creaky, 36-year-old hardware. Failed tests Wednesday suggest a fuel problem.


As Engines Sputter To Life, Vintage Spacecraft Turns Toward Moon

Tuesday, July 08, 2014

So far, so good. ISEE-3, the versatile 1978 space probe that took a detour to greet a comet in the 1980s, is now on track to get close to the moon, scientists say, though course fixes can be tricky.


A Shocking Fish Tale Surprises Evolutionary Biologists

Thursday, June 26, 2014

Who's Protecting Whom From Deadly Toxin?

Monday, April 21, 2014

Last year a scientist said he'd found a new form of botulinum toxin, and was keeping details secret to keep the recipe from terrorists. But other science and public health labs were shut out, too.


Scientists Spot A Planet That Looks Like 'Earth's Cousin'

Thursday, April 17, 2014

Kepler-186f is almost the same size as Earth, and it orbits in its star's "Goldilocks zone"-- where temperatures may be just right for life. But much is unknown because it's also 500 light-years away.
