How did feathers evolve? - Carl Zimmer To look at the evolution of modern bird feathers, we must start a long time ago, with the dinosaurs from whence they came. We see early incarnations of feathers on dinosaur fossils, and remnants of dinosaurs in a bird’s wish bone. Carl Zimmer explores the stages of evolution and how even the reasons for feathers have evolved over millions of years. Lesson by Carl Zimmer, animation by Armella Leung. View full lesson: […]

1:29 PM | This Month in Blastocystis Research (MAY 2013)

Now, we have a situation. Last month, I came up with the idea of the post series 'This Month in Blastocystis Research' developed for discussing a couple of papers on Blastocystis appearing recently in pubmed. However, this month only one Blastocystis release has emerged. It is in Turkish with an English abstract and so I'm not in the optimum position to review it. Overall, I'm not entirely clear on why the authors have chosen to publish the work. The paper is […]

Ever seen the hairy tongue of a nectar-feeding bat lap up its liquid lunch in high-speed video? via jtotheizzoe: You’re gonna like it. It’s the first detailed analysis of these prickly papillae at the tip of bat tongues, showing how they expand to catch the most of their sugary snack. Yet another example of amazing evolution, particularly in a class of life that one can argue was not really intended to hover and fly while they eat (AKA “mammals”) (via Wired Science)

10:16 AM | A Termite Burial

One of the universal aspects of living in a social arrangement with others is dealing with death. Or more specifically, dealing with the deceased. This is especially true when living close to each other as corpses tend to increase the spreading of diseases. Now imagine you live with a lot of people together, in an […]

12:57 AM | What music do dogs prefer? Bach vs. Snoop Dogg

Hey Julie,I hope you've had a fun week. I saw a new in-press publication with your name on it - "Smelling more or less: Investigating the olfactory experience of the domestic dog" - looks like a really great study, and so timely after my last post about dogs and olfactory enrichment! Looking forward to reading it (and all those other cool Learning and Motivation articles) over the weekend. So did you do your homework? Did you watch this clip from the Sydney Opera […]

7:51 PM | A medical exhibit that won't put you to sleep

"Medical Treasures at Emory" is an exhibit of historical artifacts that serve as reminders of the when doctors had a rudimentary understanding of human anatomy, performed surgery without antiseptic and used primitive forms of anesthesia for operations and dental work.The above video gives a peek at some of the objects on display through October at the Woodruff Health Sciences Center Library. Notable artifacts include one of the earliest stethoscopes from the 19th century, and a kit of Civil […]

7:26 PM | A State of Dis”array”: Two Recent Studies Highlight Common Problems Associated with Using Illumina’s 450k Array for Epigenetics Research

Epigenetic analysis is one of the hottest areas in all of biological research. Covalent modifications to DNA, proteins, and RNA, without changing the primary sequence of these molecules, are known to epigenetically regulate numerous cellular processes and contribute to many important human disease phenotypes. One of the most intensely studied epigenetic modifications is DNA methylation ...

2:01 PM | Ants Reveal How to Build a Tunnel You Can't Fall Down

It's hard to keep your footing in a steep tunnel made of loose dirt while others are scrambling around and over your body. Harder still in pitch blackness. That's why fire ants build tunnels that will catch them when they fall—a strategy human engineers might want to steal. "Slips and missteps are likely a constant, recurring feature of life underground," says Nick Gravish, a graduate student in Daniel Goldman's rheology and biomechanics lab at Georgia Tech. Yet ants have to traverse […]

11:24 AM | TMI Friday: Batteries should NOT be included

There are some days when you have to ask yourself, just what is the deal with men. I don't mean our general demeanour, or the pretensions of superiority over other genders. No, I'm talking about the strange things that men decide to do when left alone for too long.The men who happily dangle their members inside bottles, or in reach of the spinning blades of a vacuum cleaner not thinking of the consequences. With this in mind, we arrive at a case study by Bedi et al, where they […]

9:12 AM | Glucose Leaves A Bitter Taste As Cockroaches Learn to Avoid Insecticide Baits

Populations of the German cockroach (Blattella germanica) have rapidly evolved to be repelled by the glucose in insecticide baits that are used to kill them. Scientists found that the cockroaches had a ‘re-organised’ sense of taste which makes them perceive the glucose in the insecticide bait as bitter and repellent rather than sweet. Researchers first […]

After relocating to Germany, I was initially intrigued, then amused, by The Shelf that is built into many German toilets. This shelf is designed so Germans can carefully inspect their fæces before flushing. What are they looking for? I wondered. Let's face it, most people -- children and quite a... Read more
