Did Albert Einstein achieve his full potential? I’ve been pondering this question since his 100-year-old prediction of the existence of gravitational waves was confirmed this past February. After a decades-long search, astrophysicists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) triumphantly detected ripples in the curvature of spacetime.

Like many scientists, Virginia Tech civil engineer Marc Edwards chose his career to serve the public good. But his experience uncovering the Flint, Michigan, water crisis, where citizens were exposed to high levels of lead because of government and scientific negligence, has been a stark reminder of what can happen when science is misused or ignored. American Scientist’s digital features editor Katie L. Burke interviewed Edwards about his experiences and how he is working to prevent another incident like the one in Flint.

As planets are being discovered around other stars by the thousands, several scientific disciplines, including astronomy, planetary science, and biochemistry, are converging, with the goal of locating and identifying life elsewhere in the Universe. We are engaged in a search for habitability—conditions suitable for life—even though we lack a clear definition of what life is.

Climate change isn't just an environmental issue. At least not in the traditional sense.
Global warming bears all the hallmarks of environmental catastrophe: dwindling rivers, raging wildfires, dying animals and more. But those consequences aren't even half the story. Experts say climate change could devastate human health, the economy and national security, making the world a more dangerous place to live and widening the gap between the rich and the poor.

More and more women are finding it difficult to get pregnant, with mounting evidence suggesting chemicals used in plasticisers and pesticides are responsible. The consequences are estimated to cost the EU €1.4 billion per year, EurActiv Germany reports.
Avoiding chemicals completely in everyday life is impossible, despite endocrine-disrupting substances being considered a health hazard.

In a world-first, scientists in the U.K. have imaged the effects of LSD on the human brain, and we now have an unprecedented view into the effects of one of the most powerful drugs ever created.
These images not only reveal that the potent hallucinogen activates regions all over the brain — and not just the visual cortex, as previously suspected — but it shows how regions that are usually separated start signaling to each other in response to the drug, to produce some intense effects.
