Who would use chemical weapons?

Laura H. Kahn

The combatants in Syria are pointing fingers at each other. Syrian officials claim that the rebels used chemical weapons in a March 19th attack against Khan al-Assal, a town near Aleppo; the rebels say the Syrian government was the culprit. Whichever is the case, at least 25 people died and many others were wounded in the assault. The UN has decided to investigate: Secretary-General Ban Ki-moon appointed Swedish scientist Ake Sellstrom, a former weapons monitor for the UN Special Commission on Iraq (UNSCOM), to lead the investigation.

Why humans should go to Mars

Laura H. Kahn

Humans first emerged from Africa around 60,000 years ago in search of new lands to explore and colonize. Since then, we've spread out across much of the planet and even gone into low Earth orbit in the International Space Station. The need to explore new frontiers appears to be embedded in our DNA.

Undermining Obamacare

Laura H. Kahn

Now that President Barack Obama has been reelected, his Affordable Care Act, "Obamacare," will move forward, which is good news for the health, safety, and security of the United States. But setting up Obamacare and actually providing it are two different challenges. Both will be hard.

It's the season for blood-sucking bats and flesh-eating zombies, but even the most ghoulish Halloween character can't hold a candle to one of the scariest life forms around: fungi.

The One Health solution

Laura H. Kahn

The popular press is finally recognizing the important connections among human, animal, and environmental health. Environmental destruction, global trade and travel, intensive agriculture, and other human activities all lead to the emergence of previously unknown microbes that can infect across species, causing zoonotic disease outbreaks like West Nile virus, avian influenza, hantavirus, HIV/AIDS, and others. No wonder the media is paying attention.

Keeping the life sciences honest

Laura H. Kahn

When scientist Ron Fouchier, from Erasmus Medical Center in the Netherlands, presented his research at a conference in Malta last year, he described how he and his colleagues induced mutations into the H5N1 virus, ultimately giving the deadly virus the ability to become airborne and transmit infection as efficiently as the seasonal flu. Fouchier was ostensibly trying to learn more about the virus in order to protect humanity from its dangers, but his work also meant risking that the virus he created would escape the lab or be mimicked by a rogue scientist with terrorist ties.

DIY biology

Laura H. Kahn

In the nineteenth century, research in the natural and life sciences was largely self-supported. Charles Darwin had the good fortune of being born into a wealthy family, enabling him to pursue his passions as a gentleman naturalist and to develop the trailblazing theory of evolution. Darwin's good fortune ended up being science's as well.

Plastic-wrapped planet

Laura H. Kahn

We can thank billiard balls for our modern-day, plastic-filled lives. For most of human history, everyday items such as combs were made from expensive animal parts, like tortoise shells. Then, in the 1860s, billiards became a popular pastime. Unfortunately, elephants had to be killed so that their ivory tusks could be made into billiard balls, and soon elephants were rapidly being hunted to extinction. One enterprising New York billiards supplier even offered $10,000 in gold to anyone who could come up with a good substitute for ivory.

The science fiction effect

Laura H. Kahn

It's alive! Neurophysiology. Huddled around a warm fireplace one cold summer's night in 1816, a small group of friends decided to hold a competition to see who could write the scariest horror story. While vacationing in a villa by Lake Geneva, Switzerland, the friends spent their time reading ghost stories and discussing the exciting experiment being performed by the scientists of the day: reanimating dead matter.
