Scientific American launched its e-Book program this summer, starting with The Science of Sports: Winning in the Olympics. Each month, we add new titles selected from the most relevant issues facing science today. For November, we turn our attention to our immediate environment. Hurricanes. Blizzards. Flooding. Drought. If extreme weather events like these seem to be [...]

Should a scientist who believes in extrasensory perception—the ability to read minds, intuit the future and so on—be taken seriously? This question comes to mind when I ponder the iconoclastic physicist Freeman Dyson, whom the journalist Kenneth Brower recently profiled in The Atlantic‘s December issue. "The Danger of Cosmic Genius" explores Dyson’s denial that global [...]

Last week the Garrison Institute, a retreat center just a few miles down the Hudson River from my home, hosted an impressive symposium on “Climate, Mind and Behavior.” An organizer made the mistake of inviting me to the meeting’s wrap-up session Friday. As a brochure put it, the symposium brought together 75 “thought leaders and [...]

Elephants, turtles, grizzly bears and some of the world’s rarest frogs are among the endangered species in the news this week. Worst News of the Week: Armed gunmen entered the Dzanga Bai World Heritage Site in the violence-plagued Central African Republic this week and slaughtered at least 26 elephants. The site is known as the [...]

Every year up to two million people visit Haleakalā National Park in Hawaii, the only habitat for the endangered Haleakalā silversword (Argyroxyphium sandwicense macrocephalum), a spectacular and unusual plant that is now threatened by climate change. According to research published January 7 in Global Change Biology, these silverswords have suffered a dramatic population decline in [...]

The Brazilian three-banded armadillo (Tolypeutes tricinctus) can roll itself into a ball so tight that only a puma’s claws can penetrate its protective shell. But this evolutionary advantage hasn’t done much to protect the species from humans, who have turned savannah habitats into inhospitable cattle ranches and soybean plantations. Once found throughout Brazil, the armadillos—one [...]

Last year we learned that climate change could soon make Australia too hot for the cold-loving, iconic platypus (Ornithorhynchus anatinus). Now we have word of a new threat to these unique, egg-laying mammals: inbreeding, which has put the platypuses living on two small Australian islands at enhanced risk of disease. According to research published March [...]

Biologists report in the Proceedings of the National Academy of Sciences this week that they were unable to find  a pair of previously common Guatemalan salamander species — Pseudoeurycea brunnata and Pseudoeurycea goebeli — and  say they are apparently extinct. Numerous other species in Guatemala and Mexico also failed to turn up during several surveys [...]

Watching videos of fish feeding frenzies is a very emotional experience for me. You know the videos I’m talking about (personal favorites here, 0:55 in, and here). They feature a swirling, glittering mass of fish that seems to dance and flit as a single entity while being torn apart by three or four types of [...]

From atmospheric changes, to timelapse imagery from Google Earth…our planetary presence is hard to miss. This past week has seen the concentration of carbon dioxide (CO2) in Earth’s atmosphere reach a level of 400 parts-per-million, a value the planet hasn’t seen since several million years ago. To put this into some kind of context let’s [...]

President Obama has restored science to its rightful place in the White House, says John Holdren, Obama’s senior science advisor. “Science is again where it should be,” he told an audience of 200 as part of a lecture series at the Stevens Institute of Technology in Hoboken, N.J. on Wednesday, although he warned that the [...]

400 PPM: What’s Next for a Warming Planet Concentrations of greenhouse gases in the atmosphere have reached this level for the first time in millions of years. What does this portend? » On May 2, after nightfall shut down photosynthesis for the day in Hawaii, carbon dioxide levels in the atmosphere touched 400 parts-per-million there [...]

Why did James Hansen retire on April 2 after 32 years as director of NASA’s Goddard Institute for Space Studies? As he told the enterprising students of Columbia University’s Sustainability Media Lab who captured him in the following video, “I want to devote full time to trying to help the public understand the urgency of [...]

The last time the Earth enjoyed greenhouse gas levels like those of today was roughly 4 million years ago, during an era known as the Pliocene. The extra heat of average temperatures as much as 4 degrees Celsius warmer turned the tropical oceans into a nice warm pool of bathwater, as noted by new research [...]

Normally, the news that Antarctica’s summer melt season is getting longer might just be added to an endless compilation of scientific evidence that confirms the reality of global climate change. A recent research report, though, seems to run counter to the conventional wisdom. It shows that if the ice pack at the bottom of the [...]

More people in India have access to cellphones than to basic sanitation. Meanwhile, more than 7,000 villages in the northwestern part of the country suffer drinking water shortages as the water table in this breadbasket region continues to drop. And the same story can be told all over the world, according to participants of a [...]

In Barack Obama’s State of the Union address, he intoned: ” For the sake of our children and our future, we must do more to combat climate change. … If Congress won’t act soon to protect future generations, I will.” Now the president’s science advisors, a group known as PCAST for President’s Council of Advisors [...]

Ernest J. Moniz, a nuclear physicist at the Massachusetts Institute of Technology who serves on Scientific American’s board of advisors, will be President Barack Obama’s pick to replace Nobel laureate Steven Chu as Secretary of Energy. While Moniz has yet to win a Nobel, he served on the President’s Blue Ribbon Commission on America’s Nuclear [...]

The future of energy will be on display at the fourth annual summit of the Advanced Research Projects Agency for Energy, or ARPA–e. But which future? Energy innovators from start-ups, the national laboratories, universities and even oil companies will gather for three days to hear from the nation’s best about the future of energy.  The [...]

The nuclear reactor near Crystal River north of Tampa Bay will never fission again. Duke Energy has decided to shutter the troubled nuclear power plant, which has been shut down since 2009 thanks to a crack in the dome that shields the reactor. Attempts to repair the initial crack had caused other cracks to form [...]

If you listen to global warming deniers, or even much of the public, it seems like there is some stack of scientific studies somewhere that refute anthropogenic—human-caused—climate change. If someone would just let them reach into that pile and pull out a paper, we’d all see that climate change is “a hoax,” or so it [...]

There’s been quite a bit of reaction to the article published by the Economist, dated March 30, suggesting that there may be evidence that climate change has been overestimated. The data that concern those cheering the Economist writers is an apparent lack of warming since 1998 or so. Here’s a video package the Economist put [...]

So you thought the nuttiest thing we did in North Carolina this week was appoint a director of child development and early education who was against … um, early education. What’s wrong with you: have you never heard of North Carolina before? This is the NEW North Carolina, with a new governor and bulletproof majorities [...]

Earlier this week we talked about how to use whale snot for science. I especially enjoyed blog bff Scicurious‘s take on the study: Budgetary requirement: $5000 for series of expensive remote control helicopters. Source: Toys R Us. Justification: Need something that can fly close to a whale and collect snot for measurement. Also, this is [...]
