Word of the Month: Myrmecomorphy

by Kevin Zelnio in EvoEcoLab

Myrmecomorphy Part of the fun in natural history is playing word detective! Naturalists speak in greek and latin and love mashing together parts of these languages to create new, yet often very descriptive, words. This month, I want to talk a little about an awesome word – MYRMECOMORPHY. This beauteous etymological wonder is derived from from the root [...]

Cornered Rat Waves Poisoned Tool, Attacker Flees in Terror!

by Paul Norris in AnimalWise

Screams the tabloid headline… Is this the plotline for a sequel to The Planet of the Apes in which mistreated lab rats rebel against cruel animal experimenters? No, it’s actually an accurate (ok, a bit sensationalized) description of the way … Continue reading →... Read more »

A New Sexual Femunculus?

by The Neurocritic in The Neurocritic

Figure 3A (adapted from Komisaruk et al., 2011). Group-based composite view of the clitoral, vaginal, and cervical activation sites, all in the medial paracentral lobule, but regionally differentiated. We interpret this as due to the differential sensory innervation of these genital structures, i.e., clitoris: pudendal nerve, vagina: pelvic nerve,1 and cervix: hypogastric and vagus nerves."Femunulus" is a neologism for "female homuculus" The neuroanatomical definition of homunculus is a "di........

Learning to live together: new research explains how bacteria's urge to survive in our gut promotes intestinal health

by Heather in Escaping Anergy: The Immunology Research Blog

How does the immune system distinguish pathogenic bacteria from probiotic ones in the gut? Have bacteria evolved to evade immune attack in order to survive in our intestines, while at the same time playing a role in maintaining a healthy gut for us? Check out Escaping Anergy for an in-depth analysis and discussion of Round, et al.'s latest published Science paper!... Read more »

The Disconnect of the Creative Leader

I’m a strong believer that creativity is important in the workplace: even if you are not in a traditionally “creative” role (let’s say a mechanic) there is still always opportunity to solve some sort of problem that may require creative … Continue reading

Evidence of flowing water on Mars?

by Arunn in nOnoScience (a.k.a. Unruled Notebook)

Nasa reports first evidence of flowing water on Mars says Times of India. NASA better report the evidence now. They actually do report it, but with a good amount of reservation — so unlike of them, if you ask their Arsenic Bacteria – with a title reading, NASA Spacecraft Data Suggest Water Flowing On Mars.

The curious relationship between place names and population density

by Tim De Chant in Per Square Mile

Giving a name to a place is an important act. It says a place has meaning, that it should be remembered. For thousands of years, the way we kept track of place names—or toponyms—was by using our memory. Today, we’re not nearly so limited, and the number of toponyms seems to have exploded. Yet oddly [...]... Read more »

Cigarette Sadness

by Dirk Hanson in Addiction Inbox

The chemistry of sorrow during nicotine withdrawal.

When you smoke a cigarette, nicotine pops into acetylcholine receptors in the brain, the adrenal glands, and the skeletal muscles, and you get a nicotine rush. Just like alcohol, a cigarette alters the transmission of several important chemical messengers in the brain. “These are not trivial responses,” said Professor Ovide Pomerleau of the University of Michigan Medical School. “It’s like lighting a match in a gasoline factory.”

Homing In For A Blood-thirsty Meal

by Jim Ryan in Wild Mammals

Their stealthy, nocturnal habits and their penchant for feeding on blood have made them Hollywood B movie stars.

...In South America where vampire bats are common, vampires approach their prey on the ground, galloping quickly and quietly as they sneak up on, bite, and drink the blood from sleeping cows, goats and birds.

Vampire bats are the only mammal that survives solely on blood, and they need to drink it pretty much every day to survive.

...Like other bats, they feed only at night, and........ Read more »

Everyone loves to hear a good story.  And if you are reading our blog, you probably love to tell stories, too.  A good story is essential to effective communication and persuasion, and that sort of defines our wheel-house.  But I digress…  Sometimes stories are traditional “once upon a time” sorts of tales, but more often [...]

When analogies go bad

by Becky in It Takes 30

Lots has been written about the scientific method (and even I have written about it in a minor way in the past). The cycle of “make hypothesis, make predictions, test predictions, revise hypothesis, repeat” is the main thing people focus on when talking about how scientific progress happens. What’s less talked about is where the hypothesis comes from in the first place, which starts with someone (maybe you, dear reader) noticing something that needs to be explained. This is ........

High-Impact Science: EGFR – Wanna be starting something

For many, the 1980s represent social unrest and wardrobe disasters. But amidst the strikes and the legwarmers, the 1980s gave us much to be thankful for.
