A pool filled with non-newtonian fluid
Scientists say they have unlocked some of the secrets behind black holes, the gravitational fields known for sucking up light and stars from the Universe. (via BBC NEWS | Science/Nature | Black holes reveal more secrets)
Using almost every type of telescope known to humankind, Prof Marscher believes he has worked out where and how the jets - or blazars - are formed.
Using an array of 10 powerful radio telescopes, aimed at the galaxy BL Lacertae, the researchers studied a black hole just as it was sending forth a blazar jet.
RGBUV of 60 seconds per filter. The Blazar jet is visible and extra data was added with the UV exposure. Look closely at the two ellipticals and you can see many globular clusters. (via Last tuning fork images. - Astronomy.com Forums)
Ha senso dedicare le risorse della scienza a queste indagini? [Sulle reazioni fra Mentos e Diet Coke] Certamente: si tratta di un progetto scolastico che ha permesso al docente di far avvicinare gli studenti alla scienza in modo divertente, e di questi tempi c’è tanto, tanto bisogno di persone che sappiano usare il ragionamento e il metodo scientifico per analizzare la realtà.

Web created while exposed to LSD (via Spiders On Drugs)
[NASA scientists] have turned their attention from the mysteries of the cosmos to a more esoteric area of research: what happens when you get a spider stoned. Their experiments have shown that common house spiders spin their webs in different ways according to the psychotropic drug they have been given. […]
The First X-ray
In 1901 Wilhelm Konrad Roentgen was the first recipient of the Nobel Prize for Physics, […] Combining his observation with a photographic plate and his wife’s hand, he made the first X-ray photo, and thus, made it possible to look inside the human body without surgical intervention.

Un paio di video suggeriti dal Giubo: esperimenti di chimica che vanno sotto il nome di “Pharaoh’s snakes” cioè serpenti del faraone; veramente suggestivi! Ho anche trovato una spiegazione spiegazione abbastanza chiara, in inglese…
