5:31 PM | Drones in Biodiversity Research
Ecologists require spatially explicit data to relate structure to function. To date, most of such data came from remote-sensing instruments mounted on spacecraft (satellites) or manned aircraft. However, the spatial and temporal resolutions of those data are quite often not suitable for smaller local-scale investigations.Relatively cheap and portable, unmanned aerial vehicles (UAVs) better known as drones fill a gap between satellite and manned aircraft imagery and on-the-ground observations.

4:00 PM | Gene Transcription: Not Always Dictated by Histone Modifications!
The proper regulation of gene expression is of fundamental importance in the maintenance of normal growth and development.  Misregulation of genes can lead to such outcomes as cancer, diabetes and neurodegenerative disease.  A key step in gene regulation occurs during the transcription of the chromosomal DNA into messenger RNA by the enzyme, RNA polymerase II. […] The post Gene Transcription: Not Always Dictated by Histone Modifications! appeared first on EpiBeat.

4:00 PM | Both these drawings are better than my drawings of a whale
There are two things that I love about digital artist Telmo Pieper recreating drawings from childhood. One is that the images are beautiful and fantastically odd in the uninhibited way children capture so well. The second is that Pieper’s childhood drawings look … Continue reading →

3:01 PM | Baboons Trade Morning Favors for All-Day Payoffs
Primates basically invented “You scratch my back and I’ll scratch yours.” Baboons, for example, trade grooming for favors from other troop members. Social relationships are important to the monkeys. But it seems they put more effort into certain relationships depending on the time of day: in the morning, lower-ranking baboons invest more energy in grooming […]The post Baboons Trade Morning Favors for All-Day Payoffs appeared first on Inkfish.

3:00 PM | Scientists at work among the Joshua trees
When he’s not dismantling racist pseudoscience, Chris Smith studies the evolutionary ecology of species interactions. Willamette University sent along a videographer on Chris’s last field trip to study Joshua trees and the moths that pollinate them in central Nevada, and the result is now posted on Vimeo. It’s mainly geared toward showcasing how Willamette undergraduate […]

2:04 PM | Salute, il Piano della Prevenzione non va bene
“Diritto dell’individuo e interesse della collettività” secondo la Costituzione, e invece nel nostro paese la salute di almeno sei milioni di persone è a rischio a causa dell'inquinamento. Lo dimostrano i risultati del progetto Sentieri, uno studio coordinato dall’Istituto Superiore di Sanità che dal 2010 analizza gli effetti dell’inquinamento ambientale sulla salute delle persone residenti nei pressi di siti contaminati da impianti industriali […]

In attesa di raggiungere Marte nel 2030 (come previsto dai piani della Nasa), per ora dovete accontentarvi di pianificare il vostro futuro soggiorno sul Pianeta Rosso. E come ogni buon viaggiatore sa bene, per farlo è fondamentale avere una mappa. Una fortuna quindi che lo United States Geological Survey (Usgs) ne abbia appena pubblicata una, e anche la più dettagliata mai realizzata, in cui vengono raccolte le informazioni collezionate da quattro spedizioni spaziali nell'arco di […]

Last Monday the Jean-Claude Bradley Memorial Symposium was held in Cambridge (slide decks).

9:00 AM | On the mythology of natural selection: Part IV. Functional selection
Not all evolutionary change has to be based on overpopulation and resulting vicious competition for scarce resources in a cruel and bloody Nature.  Yesterday, we suggested that organismal selection, a kind of inverted natural selection, is another means by which adaptive complex traits could arise.  But there are others.Functional selectionMulticellular organisms develop from single cells. A cell is a very complex structure with all sorts of components.  Genomes code for hundreds […]
