Steve Fuller and the Value of Intellectual Provocation

Steve Fuller has been called "one of the few wild intelligences that I've seen in decades of being around academics."

Everyone, Even Jenny McCarthy, Has the Right to Challenge “Scientific Experts”

The Unforeseen Joys of Encapsulating The Present

A treasure trove of the mundane  -- Image from Wikimedia Commons

A recent study shows that underestimating the value of current experiences leads people to make time-inconsistent choices. We fail to document the present, only to wish we had done it, in the future. At the core of this contradiction is the illusion of self-immutability. We are notoriously bad at predicting how we will feel in the future, and we make the mistake of using our current mental state as a heuristic to make projections about our future feelings. Fundamentally, we do not believe that our future selves will be any different from our current selves, despite our whole life histories screaming to the contrary.

Scientists believe that idealizing one’s partner can work as a self-fulfilling prophecy, where illusion eventually becomes reality.

In such cases, love is not blind but prophetic.

Neandertals Turned Eagle Talons into Jewelry 130,000 Years Ago

American Pi: Why the Day Belongs to the U.S. (and Belize)

Pi may be a universal constant, but only two countries can natively celebrate Pi Day: the U.S. and Belize. That’s because they are the only ones (if Wikipedia is correct) to shorthand their date format so that it can match the first few digits of pi (3.1415), or March 14, 2015. Most of the rest [...]

Quick Twitter Tip for Attributing Art

When I see some amazing art posted on Twitter without attribution to the creator, especially by someone in science communication, I kind of lose it. Using Tineye.com and Google Search by Image, I usually track it down and try valiantly to communicate that they should add a credit. I usually lose the battle with my [...]

What Can We Learn From Renaissance Vegetables?

Archimboldo_220

Just throwing this out there. Has there been an attempt to track the meandering flow of selective breeding of fruits, vegetables and flowers by using still life paintings since the Renaissance? Are any vegetables significantly different in say, these face illusions by Giuseppe Arcimboldo (~1526-1593) than they would appear now? According to the Carrot Museum, [...]

Modern Day Alchemists Turn Toxic Runoff Into Valuable Pigments

Artists have long used odd things in their work – Marcel Duchamp’s urinal on a pedestal comes to mind – but even when unusual ingredients are less obvious, they can be present. As my co-blogger Glendon Mellow points out in his superb Pinch of Pigment series, everything from raw earth minerals to ground up mummies [...]

Should We Take Steps to Prevent Alzheimer’s and Parkinson’s Contagion?

One of the most intriguing new areas of research in neuroscience has to do with the discovery that proteins involved with Alzheimer’s, Parkinson’s and other neurodegenerative illnesses can contort into the wrong shape. The misshapen molecules can spread throughout the brain in a manner akin to prion diseases—the most notorious of which is variant Creutzfeldt-Jakob [...]

Does drinking alcohol—even heavily—protect against ALS?

Everyone knows that ALS is a very bad disease, an awareness underscored by the recent Ice Bucket Challenge. The death of neurons that results in paralysis can be caused by specific genetic mutations.  But in most cases, single genes are not the culprit. So researchers have looked for other risk factors that might play a [...]

We are responsible for our own actions. Of course we are.

Bio Bigwigs Go after Drugs for Parkinson’s, Alzheimer’s and ALS

Lists of the biggest challenges in brain science often start—or end—with consciousness. “End” because consciousness is considered so overwhelming a hack that it merits coming last on the list—the ultimate challenge. Consciousness probably deserves its first-or-last place of preference. But there is another entry that should be on the list that is frequently  left out. [...]

A Mouse Experiment Suggests How We Might One Day Sleep Off Toxic Memories

One area of brain science that has drawn intense interest in recent years is the study of what psychologists call reconsolidation—a ponderous technical term that, once translated, means giving yourself a second chance. Memories of our daily experience are  formed, often during sleep, by inscribing—or “consolidating”—a record of what happened into neural tissue. Joy at [...]

A Fine First Finding of Darevskia

Here's the refresher for squamate head scalation you were looking for. This image (depicting a lacertid) is from Arnold (1989). In case it isn't obvious, you need to obtain and read Nick Arnold's papers if you're really interested in lacertid diversity and evolution.

While in Romania back in 2011, I photographed the lizard you see here. It’s clearly a lacertid: a member of the Eurasian-African group that contains the familiar Lacerta sand lizards and green lizards as well as many other groups. But, beyond that, I couldn’t identify it in the field. Back at Tet Zoo Towers, and [...]

You never really hear much about shrew-opossums or rat-opossums, the small group of living, South American marsupials properly called caenolestids or caenolestoids. Small (c 20-30 cm long in total), long-tailed, mostly dark brown, and predominantly faunivorous and nocturnal, they inhabit the grasslands and forests of the western side of the Andes.

Historically, the term Pygopodidae has been used in more than one fashion. For the purposes of removing [...]
