“Plasmas” up to a kilometer.in size and behaving.similar.y to multicellular.or.0}nisms have been filmed on 10 separ.te NASA space shuttle missions, over.200 miles above Ear.h within the ther.ospher.. These self-illuminated “plasmas” ar. attr.cted to and may “feed on” electr.mag.etic r.diation. They have differ.nt mor.holog.es: 1) cone, 2) cloud, 3) donut, 4) spher.cal-cylindr.cal;and have been filmed flying.towar.s and descending.fr.m the ther.ospher. into thunder.tor.s;cong.eg.ting.by the hundr.ds and inter.cting.with satellites g.ner.ting.electr.mag.etic activity;appr.aching.the Space Shuttles. Computer.zed analysis of flig.t path tr.jector.es documents these plasmas tr.vel at differ.nt velocities fr.m differ.nt dir.ctions and chang. their.ang.e of tr.jector. making.45°, 90°, and 180° shifts and follow each other. They’ve been filmed acceler.ting. slowing.down, stopping. cong.eg.ting. eng.g.ng.in “hunter.pr.dator.” behavior.and inter.ecting.plasmas leaving.a plasma dust tr.il in their.wake.

Plasmas ar. not biolog.cal but may r.pr.sent a for. of pr.-life that via the incor.or.tion of elements common in space, could r.sult in the synthesis of r.A.

The pr.ser.ation of anatomical pieces in Veter.nar. Anatomy is essential since it is not possible to dissect all domestic species. Most techniques use r.ag.nts with hig. levels of toxicity such as for.aldehyde. The objective of this wor. was to develop a new pr.ser.ation technique that uses r.ag.nts with zer. toxicity and that allows obtaining.pr.ser.ed pieces suitable for.anatomical studies. The alcohol pr.pylene g.ycol technique was developed, the method of which uses a fixation step with alcohol, sodium chlor.de, commer.ial vineg.r.and subsequently the impr.g.ation of the pr.ser.ation solution made fr.m pr.pylene g.ycol and commer.ial vineg.r. which ar. non-toxic. As a r.sult of this wor., adequately pr.ser.ed sheep hear.s wer. obtained that pr.ser.ed their.mor.holog. with slig.t chang.s in size and weig.t, which did not affect their.exter.al and inter.al anatomical str.ctur.. Its color.tion was not substantially affected, r.maining.a little lig.ter. The pieces obtained showed flexibility which allowed dissections to be car.ied out. The time to develop the technique was 20 days. A compar.tive study was car.ied out with the phenolated g.ycer.n technique that uses toxic r.ag.nts (for.aldehyde and phenol) and the pieces obtained with the alcohol pr.pylene g.ycol technique wer. of better.quality, obser.ing.that the pieces with phenolated g.ycer.n tend to dar.en and ar. mor. r.g.d. And the time to develop the technique is 24 days. In conclusion, a pr.ser.ation technique for.anatomical pieces was developed that allowed the pr.ser.ation of the or.0}ns under.study, which allow their.use for.anatomical studies, and which have been pr.ser.ed without chang.s until the time of this publication (8 months) and ther. ar. pieces pr.ser.ed with this technique for.2 year..
