Wikipedia: The Indochinese roller (Coracias affinis) or Burmese roller, is a member of the roller bird family. It occurs widely from eastern India to Myanmar and Southeast Asia.
The Indochinese roller was formerly considered as a subspecies of the Indian roller because of a narrow hybrid zone in northeast India but a molecular phylogenetic study published in 2018 found that the Indochinese roller was more closely related to the purple-winged roller (Coracias temminckii) than it is to the Indian roller. The Indochinese roller is monotypic: no subspecies are recognized.

Rhizostoma pulmo, commonly known as the barrel jellyfish, the dustbin-lid jellyfish or the frilly-mouthed jellyfish, is a scyphomedusa in the family Rhizostomatidae. It is found in the northeast Atlantic , and in the Adriatic, Mediterranean Sea, Black Sea and Sea of Azov. It is also known from the southern Atlantic off the western South African coast and into False Bay.
It is common in the Irish Sea. It typically is up to 40 cm (16 in) in diameter, but can exceptionally reach 150 cm (59 in) or larger, making it the largest jellyfish in British waters (Cyanea capillata reaches an even larger size, but is generally smaller in Britain). On 13 July 2019, wildlife biologist Lizzie Daly dived off the coast of Cornwall in the United Kingdom, along with the underwater cinematographer Dan Abbott. The two divers shared their encounter with a human-sized barrel jellyfish, Rhizostoma pulmo. The species could typically grow up to one meter (3.2 feet) and weigh up to 25 kilograms (55 lbs). However, they are not larger than the lion's mane jellyfish.
Rhizostoma pulmo is moderately venomous but not as deadly as other species. However, there have been cases when the jellyfish has stung a human. The effects were a burning sensation on the skin, dermatitis, and ulcers which confirms it is toxic to humans. However, it does not pose a serious threat to humans. It is a favourite food of the leatherback turtle.

In European populations, barrel jellyfish evoke unpleasant or disgusting feelings[citation needed] but in Asia, they are a source of bioactive compounds used in traditional food and medicine. One study indicates that washing in aqueous solutions and the separation of high molecular weight proteins from the extract, e.g., by membrane filtration, could be a way to remove possible toxic compounds from jellyfish extracts and to concentrate potentially bioactive soluble compounds. The potentially active soluble components may have uses as nutraceutical and cosmeceutical ingredients.
🌊 შავი ზღვის საქართველოს აკვატორიაში შეხვდებით ორი სახეობის მედუზას, ძირპირასა და აურელიას. ორივე სახეობას გააჩნია შხამი, მაგრამ მათი შხამი ადამიანებისთვის საფრთხეს არ წარმოადგენს.
🔹 მედუზა ძირპირა (Rhizostoma pulmo) მალთაყვის სანაპიროზე
მედუზის ამ სახეობას აქვს მოლურჯო, ქოლგისმაგვარი სხეული, რომლის კიდეები ბოლოვდება მუქი ლურჯი, იისფერი შეფერილობის პატარა ჯიბეებსმაგვარი ქსოვილით, რომელიც გრძნობის ორგანოებს შეიცავს. აქვს საშუალოდ რვა ორალური საცეცი. „ქოლგის“ დიამეტრი საშუალოდ 40 სმ-ა, თუმცა, აღწერილია 150 სმ-იანი ინდივიდებიც.
ძირპირა ზომიერად შხამიანი სახეობაა, თუმცა, მისი შხამი ადამიანისთვის მომაკლვდინებელი არ არის. დასუსხვის შემთხვევაში კანზე იწვევს დამწვრობის მსგავს შეგრძნებას.
ხშირია ნაპირზე ამ მედუზების მასიური გამორიყვის ფაქტები. წყლის დინებისა თუ ქარის გავლენით ისინი დიდ გუნდებად შეიძლება შეჯგუფდნენ. ამ დროს ძლიერი ქარი ან ძლიერი დინება დიდი რაოდენობის ინდივიდების გამორიყვას იწვევს. წყლის ტემპერატურის უეცარი ვარდნაც შეიძლება იყოს მასიური გამორიყვის მიზეზი.
ძირპირები ხშირად გვხვდება წყლის ზედაპირთან ახლოს.

The European goldfinch or simply the goldfinch (Carduelis carduelis) is a small passerine bird in the finch family that is native to Europe, North Africa and western and central Asia. It has been introduced to other areas, including Australia, New Zealand and Uruguay.
The breeding male has a red face with black markings around the eyes, and a black-and-white head. The back and flanks are buff or chestnut brown. The black wings have a broad yellow bar. The tail is black and the rump is white. Males and females are very similar, but females have a slightly smaller red area on the face.
The European goldfinch was one of the birds described and illustrated by Swiss naturalist Conrad Gessner in his Historiae animalium of 1555. The first formal description was by Carl Linnaeus in the 10th edition of his Systema Naturae published in 1758. He introduced the binomial name, Fringilla carduelis. Carduelis is the Latin word for 'goldfinch'. The European goldfinch is now placed in the genus Carduelis that was introduced by the French zoologist Mathurin Jacques Brisson in 1760 by tautonomy based on Linnaeus's specific epithet.[ Modern molecular genetic studies have shown that the European goldfinch is closely related to the citril finch (Carduelis citrinella) and the Corsican finch (Carduelis corsicana).
The English word 'goldfinch' was used in the second half of the 14th century by Geoffrey Chaucer in his unfinished The Cook's Tale: "Gaillard he was as goldfynch in the shawe (Gaily dressed he was as is a goldfinch in the woods)".
The berries of the Virginia creeper resemble purple grapes and contain tiny crystals called oxalate crystals. These crystals are also in the leaves of Virginia creeper. If the leaves or berries are chewed they can cause irritation to the lips, mouth, tongue, and throat. (Google)

Remains of barley (Hordeum vulgare) grains found at archaeological sites in the Fertile Crescent indicate that about 10,000 years ago the crop was domesticated there from its wild relative Hordeum spontaneum. The domestication history of barley is revisited based on the assumptions that DNA markers effectively measure genetic distances and that wild populations are genetically different and they have not undergone significant change since domestication. The monophyletic nature of barley domestication is demonstrated based on allelic frequencies at 400 AFLP polymorphic loci studied in 317 wild and 57 cultivated lines. The wild populations from Israel-Jordan are molecularly more similar than are any others to the cultivated gene pool. The results provided support for the hypothesis that the Israel-Jordan area is the region in which barley was brought into culture. Moreover, the diagnostic allele I of the homeobox gene BKn-3, rarely but almost exclusively found in Israel H. spontaneum, is pervasive in western landraces and modern cultivated varieties. In landraces from the Himalayas and India, the BKn-3 allele IIIa prevails, indicating that an allelic substitution has taken place during the migration of barley from the Near East to South Asia. Thus, the Himalayas can be considered a region of domesticated barley diversification.

The clear skies gods granted me small break through the clouds during our family trip near Daylesford last week. Managed to snatch Corona Australis which I always wanted to capture.
Astrobin: www.astrobin.com/rz8a4k/
NGC 6729 and NGC 6723 are both amazing targets in the southern sky, located in the Corona Australis and Sagittarius constellations respectively.
Corona Australis is often called the "Southern Crown," and it's home to a spectacular dark molecular cloud that's pretty fantastic.
NGC 6729 is a reflection nebula, which means it doesn't emit its own light but instead reflects the light of nearby stars. It's actually part of a larger star-forming region, so what you're looking at are the birthplaces of new stars! It's a bit like a celestial maternity ward.
NGC 6723, on the other hand, is a globular cluster in Sagittarius, filled with hundreds of thousands of stars. The light from these densely packed stars has travelled around 28,000 light-years to reach us, give or take.Now, back to my attempt to capture these awesome targets.
Hope you like it

The Perseus molecular cloud, located at the junction of Taurus, Aries, and Perseus, about 1,000 light-years away from the Earth. It contains over 10,000 solar masses of gas and dust covering an area of 6 by 2 degrees, is the closest giant molecular cloud actively forming large numbers of low to intermediate-mass stars. Unlike the Orion molecular cloud, Perseus molecular cloud is almost invisible apart from two clusters, IC 348 and NGC 1333, where low-mass stars are formed.
By accumulating a very-long-time of exposure, the dust and gas show up, exhibit a complex and chaotic structure consisting of dense cloud cores surrounded by an interconnected network of filaments and sheets. Many voids surrounded by partial arcs or nearly complete rings are also seen. This complicated structure is one possible signature of supersonic turbulence.
The eastern (upper) end of the cloud is associated with IC 348 that contains several hundred young stars. Most of the star formation in IC 348 took place within the last 3 Myr, but some stars in this region formed 10 Myr ago. The apparent age spread in IC 348 may be an indication that two episodes of star formation have occurred. IC 348 appears to be an example of a region that is at or near the end of its star-forming phase.
The western (lower) portion of the Perseus cloud contains the most active region of star formation in the Perseus molecular cloud, including the NGC 1333 cluster. It contains around 150 stars with a median age of a million years, is one of the most active sites of ongoing star formation in the sky within 1500 light-years of the Sun. The molecular ridge extending south (left) from NGC 1333 contains many Herbig–Haro objects, which are bright patches of nebulosity associated with newborn stars.
Between IC 348 and NGC 1333, right in the middle of this photo, there is an area that appears pinky, which is a low-surface brightness HII region surrounded by a dust ring G159.6-18.5, which appears to lie behind the obscuration of the Perseus molecular cloud. The intense ultraviolet light emitted by the central star HD 278942 ionizes the surrounding hydrogen, giving this region its characteristic pink color. The star appears red in this photo and would have been a blue-white star if it were not obscured by dust. The presence of HD 278942 and its HII region suggests that that massive stars may have formed in the recent past within the Perseus molecular cloud.
BTW, the cloud of dust, which obscures the central star and the HII region, is called the“Flying Ghost Nebula” because of its shape.
The area to the west (lower) of the HII region looks relatively empty without too much dense dust, and particularly dark here because the extinction in this region remains high. Perhaps this dead-zone is the youngest portion of the Perseus molecular cloud, formed by the expansion of the dust ring G159.6-18.5.
There are more areas full of dense dust to the south (left) of NGC 1333, see another photo I took if you are interested: www.flickr.com/photos/steedjoy/50855451732/

From the website:
"At the time of its completion, it was the largest building in the United States west of the Mississippi River and the largest academic building in the world. Valley Sciences is mammoth in its proportions. The footprint of the building is approximately 250×500 feet; its figure eight racetrack of hallways extend for over a mile. The building has five floors, for a total of 408,500 gross SF1 of space, of which 269,500 SF is assignable space. VLSB was designed in a 'Neo-Babylonian' style; the four projecting pavilions at the corners of the building contain art deco elements such as friezes of garlanded ox skulls, griffins, and Egyptian-Babylonian priests."

Although it is close to Sagittarius, this constellation is difficult to see from Europe because of its low altitude in the sky. We can find there some of the star formation regions closest to us.
