5:33 PM | A Philosopher’s Dream
A moral philosopher had the following dream: First Darwin appeared, and the philosopher said to him, “Could you give me a fifteen-minute capsule sketch for your support of medical research using animals?” To the philosopher’s surprise, Darwin gave him an excellent … Continue reading →

Pygmy Seahorses: Masters of Camouflage via kqedscience: Tiny and delicate, pygmy seahorses survive by attaching to vibrant corals where they become nearly invisible to both predators and researchers. Now, biologists at the calacademy have successfully bred them in captivity for the first time. Finally, they’re able to study the seahorses’ amazing act of camouflage up close.  Subscribe to Deep Look on YouTube to see new videos from our pbsdigitalstudios series every two […]

4:43 PM | Milkfish fry fishery
According to the Food and Agriculture Organization of the United Nations (FAO) Milkfish (Chanos chanos) is one of the most important food fish species in the world. In Indonesia, Taiwan and the Philippines, more than a quarter of a million tonnes of milkfish are harvested annually in brackish ponds, which represents about 60% of the total fish production from aquaculture in Southeast Asia. This huge amount sourced from a single fish commodity is projected to further increase in the coming years […]

4:00 PM | Creationists and Ebola
The title of this article by Answers In Genesis is a good question: Where Did Ebola Come From? *shrug* Look, I love making fun of Creationists, but this is a great question! Ebola is not ‘supposed’ to be a human pathogen. Like many emerging infectious diseases, the natural reservoir for ebola is bats. Specifically, fruit bats.…

4:00 PM | Was ein Mensch glaubt, beeinflusst, was er tut
Manchen wird diese Überschrift vielleicht trivial vorkommen, andere wiederum, gerade, wenn von „glauben“ im religiösen Sinne die Rede ist, werden diese Behauptung vehement bestreiten. Die These, daß das Verhalten eines Menschen davon beeinflusst wird, was er glaubt, also für wahr hält (und nicht nur für wahrscheinlich, möglich, plausibel oder wünschenswert!), steht auch im Zentrum allen…

1:49 PM | Segui in streaming l'eclissi di Sole
Tra lune di sangue, comete e stelle cadenti, quest’anno gli astrofili non hanno certo avuto di che lamentarsi. L’ultimo appuntamento da non perdere arriva oggi, con la quarta eclissi del 2014. Questa volta a sparire sarà il Sole, che dalle 19:38 di questa sera fino alle 23:52 verrà coperto parzialmente dalla Luna. Un evento affascinante, che purtroppo non sarà però visibile dall’Italia: inizierà infatti sui cieli […]

12:54 PM | Ecco cosa causa il Parkinson giovanile
Tremori, rigidità muscolare e difficoltà a controllare il proprio corpo sono alcuni dei sintomi del Parkinson, che ha un’età media di esordio intorno ai 60 anni ma a volte può manifestarsi anche prima dei 40. I ricercatori dell’Istituto di neuroscienze (In-Cnr) di Milano, coordinati da Maria Passafaro, in collaborazione con colleghi dell’Istituto auxologico italiano di Milano, diretti da Jenny Sassone, hanno scoperto il meccanismo molecolare di una […]

A recent paper by Matt Helmus, Luke Mahler, and Jonathan Losos highlighted the ways in which globalization has influenced the distribution of Caribbean Anolis lizards. At the heart of this research was the relationship between commercial shipping traffic and lizard biogeography. Two more recent observations can now extend these findings well beyond the Caribbean, much, much farther […]

12:20 PM | Il dinosauro con la gobba
Con la gobba, un aspetto simile a uno struzzo e braccia con artigli incredibilmente lunghe (quasi due metri e mezzo). Appariva così lo strano dinosauro noto (ma solo in parte) dagli anni Sessanta e che grazie ai fossili di sue scheletri rinvenuti in Mongolia ha ora finalmente un aspetto completo. La ricostruzione del Deinocheirus mirificus, presentata sulle pagine di Nature, mostra che lo sconosciuto rettile fu il […]

12:20 PM | A scientific visualization of the importance of race
The image below is a phylogram, illustrating the degree of variation in a sequence of mitochondrial DNA. The concept is fairly simple: if two DNA samples are from individuals that are evolutionarily distant from one another, they’ll have accumulated more differences in their mitochondrial DNA, and will be drawn farther apart from one another. If…

12:00 PM | We’re Not Going To Take It ( #NAWD )
“Adjunct” is the word for non-tenure track faculty positions at universities. They are generally low-paying (without benefits), utterly lacking in job security and can even lead to questionable hires (further reviewed here). The reliance on and mistreatment of cheap PhDs to teach undergraduate courses may have finally reached some sort of tipping point – February […]

11:38 AM | Four Solar-Powered Animals
Photosynthesis, a process used by plants and some bacteria to convert light from the sun into chemical energy which can be later released to fuel their activities. Animals on the other hand, have to consume other organisms in order to cover their energy needs. But every rule has an exception.In recent years, researchers have discovered a small number of animals that much like plants have found a way to directly harness and feed off the Sun’s energy.1# Oriental Hornet (Vespa […]
