A few days ago we woke up to the news that the New York Times is eliminating their environment desk. Predictably, the immediate reaction of many was “oh, noooo!”. After all, whenever we hear such news, about a science or health or environmental desk being eliminated at a media organization, this means the reporters and [...]

When, if ever, is lying justified? I talked about this conundrum this week in a freshmen humanities class, in which we were reading Immanuel Kant on morality. Kant proposed that we judge the rightness or wrongness of an act, such as breaking a promise, by considering what happens if everyone does it. If you don’t [...]

When the demand of my job and my family life allow, I try to take advantage of the fact that I live in California by maintaining a vegetable garden. One of the less pleasant aspects of vegetable gardening is that, every winter and spring, it requires me to embark on a program of snail and [...]

When we think about food, how often do we think about what it’s going to do for us (in terms of nutrition, taste, satiety), and how often do we focus on what was required to get it to our tables? Back when I was a wee chemistry student learning how to solve problems in thermodynamics, [...]

Like other scientific disciplines, chemistry is in the business of building knowledge. In addition to knowledge, chemistry sometimes also builds stuff — molecules which didn’t exist until people figured out ways to make them. Scientists (among others) tend to assume that knowledge is a good thing. There are instances where you might question this assumption [...]

I’ve already been nicknamed Jeffery. Now, Jeffery, I should mention, is the ship’s jack-of-all-trades. In 2009 I sailed with him and Algalita to the Pacific Garbage Patch and Captain Dale decided I just might be as helpful as Jeff. Well, I can tell you right now that I don’t know how to repair a broken [...]

Editor’s Note: A team of researchers led by John Kessler, Texas A&M College of Geosciences chief scientist and assistant oceanography professor, has traveled to the Deepwater Horizon disaster site to study the methane leaking into the Gulf of Mexico (along with tens thousands of barrels of crude oil) daily at the site of the damaged [...]

Editor’s note: Marine geophysicist Robin Bell is leading an expedition to Antarctica to explore a mysterious mountain range beneath the ice sheet. Following is the sixth of her updates on the effort as part of ScientificAmerican.com‘s In-Depth Report on the "Future of the Poles." McMURDO STATION, ANTARCTICA—For a geologist, Antarctica can be a very frustrating [...]

Newer homes are remarkably energy tight thanks to superior insulating materials that are in wide circulation today. The energy savings can be substantial – homeowners can use up to 60% less energy in the most efficient green homes. Now, a study published by a team of researchers in Building Research & Information makes it clear [...]

While reading about social science and environmental communication, I’ve noticed a gap between how environmentalists in the United States view personal space and how their audiences perceive it. If environmentalists tell audiences not to "say ‘eww’ to thrift stores," avoid public transit, or live in suburbs, they may encounter resistance—not because their audiences are opposed [...]

The Future of Water: A Startling Look Ahead, by Steve Maxwell, with Scott Yates, Published in 2011 by the American Water Works Association, Denver Colo., ISBN 978-1-58321-809-9 Full disclosure: I answered an open e-mail solicitation for reviewers of this new book and received a review copy for free in exchange for my promise of a [...]

In 2011, the world will emit more than 35 billion tons of carbon dioxide. Every day of the year, almost a hundred million tons will be released into the atmosphere. Every second more than a thousand tons – two million pounds – of carbon dioxide is emitted from power plants, cars, trucks, ships, planes, factories, [...]

On Friday, March 11, Japan was rocked by an earthquake. People were displaced, a nuclear reactor was in trouble, and the world watched as a tsunami flooded Japan, threatened the islands of the Pacific, and ultimately hit the western coasts of North and South America. Chris Rowan pointed out that “Very little of the devastation [...]

On Wednesday March 9, energy and film experts gathered at the original Austin City Limits studio on The University of Texas campus to discuss the role of energy and movies in our lives. The event was hosted by Dr. Michael E. Webber, and featured a panel of energy and film experts: author Sheril Kirshenbaum, producer [...]

It’s loud out there. All that banging and driving and dumping and flying and building we do is making the world noisier and noisier. While humans don’t seem to mind the sounds, and when we do we just put in our earplugs – animals are dealing with all the racket we make in interesting ways. [...]

Part 2: A Little Research Goes a Long Way (see Part 1: Epiphany from up high: Can a suburban family live sustainably?) Tracking down an energy auditor on the cusp of the 2010 deadline for energy efficiency rebates proved tricky. Yet on a frigid morning in early January, David Pocklington and Shane Matteson of Energy [...]

There we were, racing through the stratosphere on a short flight home from Baltimore to Atlanta (577 miles and approximately 230 pounds of carbon dioxide per person). My husband, Mike, was tuned to his iPod, and me to my book, How, Flat and Crowded 2.0 when a sentence in the section on oil and geopolitics [...]

I’ve been on holiday for the last few days, so haven’t had much time to read papers about bacteria. What I have been doing, however, is looking at butterflies. Since my sudden and unexpected discovery that I was obsessed with them I have since bought a butterfly field guide and now try to identify them [...]

In order to survive in complex and interesting environments in the wild, bacteria have a whole arsenal of chemical products that they make within the cell. These chemicals are used for signalling, defence and communication between bacterial cells. One particular group of these chemicals is called the polyketide group, which I have a particular fondness [...]

The soil is not just a single environment. To human eyes it may look like a brown layer of plant mush that fits into the rocks, but for a living environment it is highly complex. Not only must the bacteria that live within it share their space with small animals, protozoa, and fungi, but they [...]

Thursday 26th July saw the launch of SciLogs.com, a new English language science blog network. SciLogs.com, the brand-new home for Nature Network bloggers, forms part of the SciLogs international collection of blogs which already exist in German, Spanish and Dutch. To celebrate this addition to the NPG science blogging family, some of the NPG blogs are publishing posts focusing on “Beginnings”. Participating in this cross-network blogging festival is nature.com’s Soapbox Science blog, Scitable’s Student [...]

There’s been a lot of focus on the human microbiome recently, and while I’m obviously thrilled at anything which makes people think more about bacteria it’s easy to forget that it isn’t just humans who provide internal living space for bugs. Bacteria are everywhere, inside and among every living creature, and some of them form [...]

Unlike animals, plants do not have a circulating blood system containing cell capable of fighting off bacterial invasion. Instead, they have to rely on various other techniques, which I covered in detail way back on my old Field of Science blog. One method they use is to kill off cells that are close to a bacterial or [...]

I’ve had an insanely hectic yet very important and productive time at work this month, so my blogging has fallen by the wayside. Next month I’ll be back to my normal blogging schedule, and just to kick things off here’s a post that first appeared in my old “Life of a Lab Rat” blog Niches [...]

A species is one of those things that is harder to define than it looks. While it’s clear that (for example) a rat is a different species than a dog, the more closely related animals get, the harder it is to properly put them into species. Usual definitions involve the sharing of physical characteristics (although [...]

Still on my honeymoon, far away from any form of internet, so this is another old post from my previous blog. The post itself is not one of the best I’ve written, but the subject matter was so fascinating I feel it needed reposting! This post came to light due to Captain Skellet (whose been around [...]

I’ve mentioned magnetic bacteria a couple of times now, so I got quite excited when Lucas Brouwers alerted me to a recent paper in Science (ref below) that explored a whole new group of magnetic bacteria. As I’ve covered before, these magnetotactic bacteria contain small nanoparticles of magnetic material which allow them to swim along [...]

In a draft assessment of the proposed Keystone XL pipeline, consultants for the U.S. State Department judged that building it would have no significant impact on greenhouse gas emissions. Why? Because the analysts assumed the tar sands oil would find a way out with or without the new pipeline. The U.S. Environmental Protection Agency does [...]

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 [...]

This afternoon, President Barack Obama will ask Congress to direct our cars, trucks and buses to a realm that doesn’t include gas stations. During a visit to Argonne National Laboratory, he will call for $2-billion energy security trust fund dedicated to research to boost automobile efficiency, enhance battery technology and expand the use of biofuels, [...]

There are nano-sized particles in your food. Does this make you nervous? A new report from an environmental health group, As You Sow, raises concern about nanoparticles in some popular sweets. The group says it found particles of titanium dioxide less than 10 nanometers in size in the powdered sugar coating on donuts from Dunkin’ [...]

A group of college and high school students has designed a Star Trek-inspired sensing device that can beam environmental data to a smart phone.  The team developed their project during a summer internship program run by the Wright Brothers Institute and the Air Force Research Laboratory. and shared their results at this fall’s World Maker [...]

Predictions of tipping points in ecology, climate change, medical outcomes and other complex systems are a primary goal for many researchers. The pursuit of insights into the timing of critical transitions is no easy way to make a living, particularly because random events can trigger such changes and warning signs are easily missed or misinterpreted. [...]

Imagine an electronic medical implant that, like dissolvable stitches, could disintegrate after it is no longer needed. An innovative combination of silk and silicon have now been used to create just such ephemeral but effective devices, including diodes, transistors, mini heaters and stress sensors. A flexible device that is just nanometers thick can fight post-surgical [...]

During the 352-year life span of the Royal Society, the human population has risen from less than one billion people to seven billion and counting. That boom has been supported by science and technology—Watt’s coal-fired steam engine, Haber and Bosch synthesizing nitrogen fertilizer, Fleming’s discovery of penicillin—and continues today as the world’s population expands at [...]

Two provocative ways to see long-term changes on earth are currently being promoted in honor of Earth Week. A Web site by NASA, and an app from HarperCollins, both show striking side-by-side satellite images of locations that have changed dramatically over time spans of up to 30 years or more. The primary intent is to [...]

The world’s population will cross the 7 billion mark this month and is projected to reach more than 9 billion by 2050. So many more people, plus rising living standards, mean that global agriculture will have to double food production by mid-century. Yet farming and ranching already exact a daunting toll on the environment: burn [...]

You’ve heard us regularly crying for help here in North Carolina as our legislature has tried to turn science on its head. So, committed to keeping you posted, we here at the Plugged In Reign of Error desk thought you’d want to know what’s up. For a moment, anyhow, our governor and his vetoproof Republican [...]

At the risk of becoming Plugged-In’s “Those crazies are at it again” correspondent, I would like to bring your attention to two noteworthy developments regarding sea level and politics, and then I hope to wash my hands of the topic — with higher sea levels making hand-washing especially convenient, of course. The first concerns the [...]

An open letter to the knuckleheads at the International Telecommunication Union: Dear Knuckleheads: I’m hearing that you guys are considering dropping the Leap Second – the second added every year or so to Coordinated Universal Time to make sure CUT, kept by incredibly accurate and complex atomic clocks, squares as closely as possible with astronomical [...]

In Tyson Schoeber’s class at Nootka Elementary School in Vancouver, 15 fourth through seventh graders struggle to read, write or do math at a level near that of their peers in other classes. Ten-year-olds have entered Schoeber’s program, called THRIVE, virtually unable to read independently (see “One Man’s Mission to Save Struggling Students”). Yet Schoeber [...]

One of the most fascinating aspects of art is that two artists can use the same exact materials and create vastly different works. Last week, I posted an interview with Heather Knight, an artist who creates abstract porcelain tiles inspired by nature’s patterns and textures. Today, I introduce Kate MacDowell, another artist working in unglazed [...]

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 [...]

Happy Earth Day, everyone! In honor of the day, here’s a modified re-post of piece I wrote recently for LAist. Figure 1: Photo by poloroid-girl via LAist Featured Photos on Flickr. The great philosopher Kermit the Frog once said, “It’s not that easy being green.” Maybe he was on to something. You can’t walk three [...]
