A photographer has captured beautiful images of how snow has blanketed sand dunes in the Sahara Desert as temperature significantly dropped. Ice created stunning patterns, however, there probably wasn’t quite enough to build a life-size snowman or an igloo just yet, The Metro reported.

The area is more commonly known for its hot and dry climate – but very rarely, this striking sight is seen.

Karim Bouchetata took the photos near the town of Ain Sefra in northwest Algeria on Jan. 20, where temperatures fell to -2C. The area is around 1,000 meters above sea level and surrounded by the Atlas Mountains, so it has sometimes seen snow before.

Even then, however, the phenomenon is rare – with snow just five times in the last 24 years in 1979, 2016, 2018 and 2021.

Ain Sefra is known as ‘The Gateway to the Desert’. The Sahara Desert covers most of Northern Africa and it has gone through shifts in temperature and moisture over the past few hundred thousand years. Most of the time, the desert is much hotter with an average temperature during the day of 38C – and a heat record of over 50C.

Snow is very rare in the desert because there is not usually enough water in the air for it, even though it can get very cold at night.

Symbols at Old English Buildings Not ‘Witches Marks’

Over the years, English Heritage and Historic England have claimed to have identified large numbers of “witches’ marks” or “ritual protection symbols” on the walls of historic buildings, including medieval churches and houses.

Now a leading architectural historian has said there is “absolutely no evidence” that these marks have anything to do with witches or any “mystical meanings.”

Daisy wheels, or hexafoils, are among symbols that are no more than the marks of stonemasons who worked on those buildings, according to Jennifer Alexander, a professor of architectural history at Warwick University and author of a new study.

She told the Guardian: “Do you remember at school when you were first given a pair of compasses and you made a daisy wheel? It’s that. There are hundreds of such marks and they tend to be [of] varying degrees of skill. It’s much more the sort of thing you would use to train apprentices with, giving them skills in using tools on intractable surfaces like stone.”

She said such marks were “practical geometry” being taught and tried out. “The daisy wheels are practices for drawing on stone and learning how to use compasses with straight edges to do geometry.”

Ridiculing their identification as “witches’ marks,” Alexander said: “Anything on a stone building that looks like a design gets picked up as these things now. There’s absolutely no evidence they were ever used like that.”

Alexander said: “There’s no evidence that these are witches’ marks. What they’re telling us is that when that barn wasn’t needed for farm produce, it was either a schoolroom or a mason’s training shop.

“There are a huge number of designs on the walls there and they vary enormously in skill. If you are drawing a circle with a pair of compasses, you get three-quarters the way round and it’s very difficult to make a nice clean line because your wrist is upside down. When you’re doing it on paper, it’s bad enough. When you’re doing it on stone, it’s even harder. So people have to be trained.”

She added: “There are things to ward off the evil eye, but they are a more generic thing ... These are parts of the mechanisms by which buildings are constructed ... Marks that look like a capital W or an M are mason ciphers. They can help put things together in the right order if you are building something. Or they can identify whose work it was.”

Ancient Cave Discovery Reshapes Scientists' Understanding of Neanderthals and Modern Humans

Groundbreaking archaeological research from southern Türkiye suggests a surprising new narrative: modern humans and Neanderthals may have lived as friends, sharing elements of their culture.

Evidence unearthed at Ucagizli II Cave indicates that these two closely related human species coexisted between 50,000 and 60,000 years ago, adopting remarkably similar technologies, survival strategies, and even symbolic traditions between 50,000 and 60,000 years ago, according to The Independent.

The revelations could profoundly reshape scientists’ understanding of how Homo sapiens and Homo neanderthalensis interacted during a pivotal period in human evolution.

While modern humans undertook their significant “Out of African” migration into Eurasia, fossil evidence from the Levant – a crucial geographical corridor connecting the two continents – has historically remained relatively scarce.

To shed further light on this era, an international team of researchers from Türkiye, France, and Japan, including scientists from Kyoto University, embarked on extensive excavations at Ucagizli II Cave.

Over a painstaking five-year period, archaeologists meticulously excavated the site millimeter by millimeter.

Their efforts uncovered compelling proof that both Neanderthals and modern humans not only occupied the cave but also used identical stone tool technologies and employed the same hunting methods.

Crucially, researchers also discovered clear indications that the two groups engaged in shared behaviors extending well beyond the necessities of daily survival, hinting at a deeper cultural exchange.

Both Neanderthals and modern humans appear to have deliberately collected the same type of marine seashell, despite it having little or no value as a food source.

Such shells had previously been regarded as being associated only with modern humans.

The researchers say the shared preference for these non-utilitarian objects may point to the exchange of symbolic or cultural practices between the two species.

“Our findings indicate a deep level of cultural interaction,” said a corresponding author Naoki Morimoto of KyotoU.

“These two distinct but closely related human groups were not just adapting to the same environment: they were probably sharing symbolic preferences.”

The modern human remains recovered from the cave have been dated to between 50,000 and 60,000 years ago, placing them within the period when genetic evidence suggests modern humans were dispersing from Africa into Eurasia.

According to the researchers, the individuals may represent close relatives of the population that gave rise to all present-day people living outside Africa.

Alternatively, they could belong to a previously unknown population descended from an earlier migration into the Levant.

The team says the discoveries help fill a significant gap in the archaeological record, offering new insights into how modern humans and Neanderthals may have lived, interacted and exchanged ideas during a prolonged period of coexistence spanning more than 20,000 years.

Germany has recorded an estimated 5,120 heat-related deaths so far this year, most of them in late June when weekly average temperatures far exceeded 20 degrees Celsius, the Robert ‌Koch Institute (RKI) ‌for public health ‌said on ⁠Thursday.

Around 4,270 of ⁠the deaths were among people aged 75 and older, the RKI said in a weekly report. More women ⁠than men died, mainly ‌because ‌they make up a higher ‌share of the very old.

The ‌German data add to a grim picture across Europe. The EU's Copernicus Climate ‌Change Service said in a bulletin on Thursday ⁠that ⁠Western Europe had its hottest June on record with an average of 20.74 degrees.

National authorities have reported more than 4,700 excess deaths during the June 20-28 heatwave in France, Belgium, Spain and the Netherlands.
