In the 1960s and '70s, population bomb reality was said to be as settled as climate change is today. No less than Dr. John Holdren, current Obama administration Science Czar, co-authored a book called Ecoscience, which argued that forced sterilization and mass abortions might  be necessary, and even viable under the equal protection clause of the Constitution.

This morning, a large active region on the sun erupted with another X-class flare, its fourth since Oct. 24th. 

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

The first images of a nova during its early fireball stage - when it ejects material and gases expand and cool - have been delivered from a nova that erupted last year in the constellation Delphinus.  

A nova occurs after a thin layer of hydrogen builds up on the surface of a white dwarf--a highly evolved star with the mass of the sun packed into the volume of the Earth. A normal star accompanies the white dwarf in a binary star system, providing that hydrogen as the two stars orbit each other.

We never miss pharmaceutical companies until they are gone.

Lawsuits, terrifically expensive drug development cycles and trials coupled with a short window for sales before a drug is declared out of patent and therefore generic has meant companies are abandoning markets that are not lucrative, like antibiotics. Critics who believed drug companies were evil and greedy have found that government is incapable of doing applied research - and that is leaving a huge void.

If you take an online practice test, which answer is most likely to stick with you, the ones you got correct or that one you got wrong?

A new paper finds that making mistakes while learning can benefit memory and lead to the correct answer, but only if the guesses are close.

"Making random guesses does not appear to benefit later memory for the right answer , but near-miss guesses act as stepping stones for retrieval of the correct information – and this benefit is seen in younger and older adults," says Andrée-Ann Cyr, a graduate student with Baycrest's Rotman Research Institute and the Department of Psychology at the University of Toronto. 

Not everyone who contracts the Ebola virus dies, the survival rate is actually around 30%, which means some kind of immunity to the disease is possible.

Experimental treatments and vaccines against Ebola exist but there was little interest from governments in streamlining the bureaucracy before the recent outbreak, so they have not undergone phase 2 trials - the U.S. Congress did add $90 million to the $29 billion budget of the National Institutes of Health after Director Francis Collins said money was the thing that had prevented a vaccine in the past.
