Are you lost in the countryside. You know that to find the right way or you have to go north or south. You do not have the compass, the sun is hidden and is also looking noon quidni not help you. There are only cows. How do you identify where is the north-south axis? Know that there are electricity pylons nearby.

Nothing could be easier! Just look at the body axis of the cows! According to a recent study, the cows tend to align along the axis of the geomagnetic and grazing land. Pavel Nemec and coworkers have analyzed the alignment of 1699 cows and 653 deer using satellite images and aerial taken from Google Earth and found that the proximity (distance of less than 50m) from pylons and low-frequency electromagnetic fields disrupt the alignment.

The study was published in PNAS and the news was also reported by Nature .

liquid nitrogen against Mr Frosty. Who knows how to make better ice cream? The PCR Song

The use of good raw materials lead (often) a good product. Certainly this is not the discovery of hot water! Among the ingredients of ice cream are milk, cream, egg yolks and sugar, but another key component of the dessert are the crystals ice.

Yet the radius of ice crystals in ice cream are essential for obtaining a good ice cream. The smaller the crystals and is more creamy, fluffy and omeogeneo. Crystals of larger size gives a grainy texture and more coarse.

A slow freezing results in a few large crystals while a quick congelament promotes the formation of many more nucleation sites and thus a more smaller crystals.

For this reason, the use of liquid nitrogen in the preparation of ice cream from a good consistency. The liquid nitrogen is at a temperature of about -196 ° C. If you use this drug for freeze the temperature drops quickly, forming so many small ice crystals. In contrast, using Mr. Frosty (a Nalgene container produced by using the shell in the process of cryopreservation of cells containing isopropanol so as to control the temperature drop that is about 1 ° C per minute), results in a grainy ice cream with a few large crystals because the temperature drop is gradual and slow. Liquid Nitrogen vs.

(Sulla musica di Ricominciamo di Adriano Pappalardo)

Lasciami replicare
Lasciami omologare
Io senza cross-over non so stare…
Io non posso restare
Senza appaiare
ne chinetocoro ne spindle
non sono capace
di stare a guardare
questo insieme di basi
e poi non formare
una rottura filamentare
e mettermi in mezzo
gridarti migriamo…
ricombiniamo…
So che devo migrare
È un mio dovere
Durante la profase
Che ci posso fare
Son le nucleasi
però fan le rotture
Mi appaio, t’invando
E rami-fichiamo
Perchè ho lo SNP giusto
Evviva il duplex
Ricombiniamo
Ricombiniamo
Ricombiniamo
Cosa vuoi che ti dica?
Io sono un’allele
guai a quello che è mutato
So che ti piace la frequenza
di ricombinazione
ma richiede enzimi
non solo energia
per ben mescolare
e fare variare
questi geni che abbiamo
evviva I chiasma
behind all
yet I say unto you ...
