Being with Jane Goodall via thatssoscience: jtotheizzoe: Jane Goodall shares an important message on the need for empathy in science, and how viewing intelligent and social non-humans as “animal beings” can help us not only treat them with the respect they deserve, but also understand how their complex biology and behavior is intertwined with our own.   (from NOVA’s Secret Life of Scientists) I needed this today.

4:41 PM | Darwin, sexist asshat
That same bozo who sent me the Hitler quote sent me another image in reply: Fair enough. Darwin got a lot of things wrong. I’m actually going to be lecturing my intro biology students on where Darwin screwed up in a few weeks, focusing mainly on his bad genetics, but I’ll toss that quote into…

3:46 PM | 3D Chromatin Organization, Transcription, and Behavior
The chromosomes of differentiated cells contain heterochromatic and euchromatic compartments. Heterochromatin is highly condensed and associated with repressed transcription, whereas in euchromatin  transcription is generally active. Spatial organization of heterochromatin can vary vastly among different differentiated cell types1. In contrast to differentiated cells, embryonic stem cells contain only sparse heterochromatic ... The post 3D Chromatin Organization, Transcription, and […]

3:26 PM | Prof. Erland Stevens's online medicinal chemistry course
This spring I had a post up about an online medicinal chemistry course taught by Prof. Erland Stevens of Davidson College. It looks like the course was received quite well, with 14,000 students signing up. Now it's going to be taught again, starting from October 13th. Here's some information about the course that Prof. Stevens sent along; from the list of topics it seems to cover most major aspects of the basic principles and practice of drug discovery from a chemistry perspective. Would […]

3:04 PM | Sharing my byline and other adventures in punk rock
I gingerly slid the disc into my car CD player and braced myself against the steering wheel for the anticipated onslaught of noise. Instead, a voice, rich and smooth like molten chocolate, began to pour. With that, my introduction to The Offspring’s multiplatinum album “Smash,” and punk rock in general, began. Up until that point, […]

2:57 PM | Lo Spazio in mostra al Palazzo delle Esposizioni
Ghiacciai in rapido scioglimento, mari che si innalzano minacciando la terra emersa, fenomeni atmosferici naturali e artificiali, foreste in diminuzione, terreni agricoli come mosaici, deserti dove la vegetazione diminuisce progressivamente e l’acqua scarseggia, megalopoli sovraffollate (ma bellissime viste dall’alto). Sono solo alcune delle immagini satellitari e videoinstallazioni fornite dall’Agenzia Spaziale Europea (Esa) in mostra al Palazzo delle Esposizioni di Roma […]

2:49 PM | Opportunities for High School Students to Learn at the BTC Institute
Paul Simon famously sang about what it was like to engage as a learner in a high school environment—though his lack of education certainly hasn’t hurt him any, I do wonder about reading the “writing on the wall”. Frequently, in Education, we talk about the challenges of preparing students for careers that have yet to […]

This week’s tip of the week highlights the MEGA tools–MEGA is a collection of tools that perform Molecular Evolutionary Genetics Analysis. MEGA tools are not new–they’ve been developed and supported over many years. In fact, on their landing page you can see the first reference to MEGA was in 1994. How much computing were you […]

1:19 PM | Gli eventi astronomici del cielo di ottobre
Niente Super Luna questo mese, ma non temete, perché al suo posto si potranno osservare ben cinque fasi lunari, una pioggia di stelle cadenti e una rarissima cometa marziana. È questo infatti il ricco bottino che attende astronomi e appassionati nel cielo di ottobre. Non è comune, ma comunque possibile che in un mese possono susseguirsi ben cinque fasi lunari (solo a febbraio è impossibile, quando ve ne sono tre), e nel 2014 in effetti è già successo a […]

1:01 PM | Can Lizards Adapt to a Warming World? An Experimental Study Demonstrates Natural Selection for Performance at Warmer Temperatures
In these times of rapidly changing climates, a major question is whether species will be able to survive. Essentially, they have two options: either shift their geographic ranges to stay within their ancestral niches, or adapt to new circumstances. Or, of course, go extinct. In recent years, evolutionary biologists have come to realize that evolutionary […]

Biology concepts – undulipodia, convergent evolution, parallel evolution, homologous structures, re-emergent evolution, atavism, flagella, eukaryote, prokaryoteThis represents the evolution of cell phones over the last couple of decades. The latest models aren’t there since things are changing so fast. Evolution in biology doesn’t always work this way, one thing leading directly to another, sometimes you have to go back to a rotary phone go forward to an iPhone, and sometimes […]

12:00 PM | Temperature and reproductive success in arabidopsis
Seed yield and dormancy status are key components of species fitness that are influenced by the maternal environment. Huang et al. grow the Arabidopsis thaliana ecotype Burren (Bur), which is adapted to a cool, damp climate, under conditions normally experienced by the Cape Verdi Isle (Cvi) ecotype, which is adapted to a hot, dry climate. They […]

11:27 AM | Contro i brufoli, batteri “mangia sudore”
Scordatevi saponi, creme e detergenti. Il futuro della lotta all'acne potrebbero essere i “batteri mangia sudore”. Da uno studio condotto dalla Aobiome Llc, una società di biotecnologie specializzata in prodotti cosmetici, sembrerebbe infatti che una classe di batteri noti come Ammonia-oxidizing bacteria (Aob), o batteri nitrificanti, siano in grado di neutralizzare l'ammoniaca contenuta nel sudore, migliorando sensibilmente la salute della pelle, e contrastando disturbi […]
