A hardy grey feline in Russia got a new lease on life after suffering from frostbite. The female cat, named “Dymka” (Russian for “mist”) was found in 2018, buried in the Siberian snow, with four frostbitten paws, ears and a tail.

The frostbite was so extensive that veterinarians had to amputate those limbs. But researchers at the Tomsk Polytechnic University (TPU) in Tomsk, Russia created specially-designed titanium paws for the cat, then fused them to her leg bones. The cyborg-like appendages combine titanium rods with flexible black “feet” with textured, grippy bottoms. The new limbs were implanted in July 2019. Just 7 months-later, scientists posted adorable video of Dymka stretching, playing and strolling.

The world’s largest telescope just took the highest resolution picture ever of our home star, and it looks just like caramel corn. The incredibly detailed image revealed details about the sun’s roiling magnetic field that previously only showed up as tiny specks. This gorgeous image of the sun was captured with the Daniel K. Inouye Solar Telescope (DKIST), perched high on the Haleakala mountain on the Hawaiian island of Maui.

The new telescope isn’t even fully completed yet, but when it comes online, it will delve into one of the sun’s biggest mysteries: Why the sun’s outer layer, called the corona, is hotter than its visible surface. Researchers unveiled the image during a news conference on Friday, Jan. 24.

Asking what’s the world’s tiniest dinosaur is a bit of a trick question. (Hint: birds are actually dinosaurs). But the tiniest known extinct dino was the wee feathered creature known as Ambopteryx longibrachium. This pint-sized specimen, found in northeastern China, measured a mere 13 inches (32 centimeters) long and weighed just 11 ounces (306 grams).

The Jurassic era creature sported thin, membranous wings like a bat. And it may not have prowled Jurassic skies alone; another bat-winged dino, Yi qi, also known the “dark knight” of the Jurassic, was also discovered in China. Yi qi had a wingspan of 23 inches (60 cm) and a weight of 13 ounces (380 grams).

Sky dunes

When skygazers in Finland trained their eyes on the heavens in 2018, they never expected to discover an entirely new phenomenon. But that’s exactly what happened when they noticed eerie, undulating waves of glowing green light.

The enthusiasts were part of a Facebook group dedicated to cataloguing and discussing aurora, and contacted an expert about the luminous light shows — Minna Palmroth, a professor of computational space physics at the University of Helsinki. When Palmroth saw images of these mesmerizing green dunes, she soon realized they had identified an entirely new type of aurora.

These gorgeous light shows, known as “the dunes,” occur when disturbances in the upper atmosphere, known as gravity waves, interact with aurora. Gravity waves move the molecules in the atmosphere around, creating alternating folds of oxygen-rich and oxygen-depleted sky. As charged particles from the sun slam into the atmosphere, the areas with more oxygen glow green, creating the alternating stripes characteristic of the dunes.

Paleontologists in Utah uncovered the missing skull of a towering, meat-eating dinosaur.

The skeleton of this massive carnivore was first found in a hunk of rock so huge they needed explosives to excavate it and a helicopter to transport it. But when first discovered, the skeleton was missing its head. Scientists only found the skull later, using a radiation detector.

Dubbed Allosaurus jimmadseni, after paleontologist James Madsen Jr. (1932-2009), the primeval monster had horns over its eyes and 80 razor-sharp teeth.The fearsome predator grew up to 29 feet long (9 meters) and weighed 4,000 lbs. (1.8 metric tons). A. jimmadseni is the oldest allosaurs known to paleontologists, predating the other North American species by 5 million years. Researchers described the allosaurus in a Jan. 24 study in the journal PeerJ.

Doomsday Glacier

A torpedo-like robot named Icefin has ventured to Antarctica’s most dangerous glacier, and found something extremely troubling. The Thwaites glacier, nicknamed the Doomsday glacier because it is melting so fast, is bathing its underbelly in a sea of surprisingly warm water.

The water at the sea’s boundary is more than 3.6 degrees Fahrenheit (2 degrees Celsius) warmer than freezing, according to news reports. That’s even worse than climate scientists expected, and spells trouble because Thwaites glacier not only accounts for a huge amount of sea level rise, but its floating ice sheets also keep the rest of the glacier from flowing into the sea.

A massive ancient Egyptian burial ground, filled not only with the mummies of high priests, but also the thousands of their “servants”, was found at the site of Tuna-el-Gebel.

The site includes at least 20 stone sarcophagi, 700 amulets and 10,000 “shabti” figurines, which were meant to serve the dead during the afterlife.

Officials with the Egyptian ministry of antiquities announced the finding on Thursday (Jan. 30) and they expect that many other mummies could be unearthed.

Farewell, Spitzer

Few cosmic vistas excite the imagination like the Orion Nebula, an immense stellar nursery some 1,500 light-years away.

NASA’s best infrared eye in the sky, the Spitzer Space Telescope, was officially turned off on Thursday (Jan. 30) It winked on in 2003 and was meant to run for only 2.5 years, but ran more than a decade longer than that. During its 16-year run, the iconic telescope captured stunning images of the cosmos, discovered never-before seen rings around Saturn, and spotted exoplanets circling around the cool, red-dwarf star known as Trappist-1.

One of its most gorgeous snapshots is this ethereal image of the Orion nebula, taken in 2006.

This massive star factory, located 1500 light-years away from Earth, shows young hot stars glowing in red, along with still forming stars in a reddish hue.

A camera onboard the Landsat-8 satellite captured this gorgeous image of ash and steam billowing out of Japan’s Nishinoshima volcanic island, about 600 miles (1,000 kilometers) south of Tokyo, NASA’s Earth Observatory reported. During this recent activity, seen on Jan. 26, lava oozed into the ocean and sent steam plumes into the air near the coastline. Emissions from the volcanic island continued from Jan. 15 to Jan. 21. The tiny island is actually the submerged caldera (a volcanic depression) of the northern Volcano Islands of Japan. Calderas form as a result of giant eruptions, when loads of magma from below come to the surface and the land once held up by that mass sinks under its own weight.

Neon green spider

Scientists recently discovered a brilliant-green spider that uses math to weave its web. Because of the stunningly precise geometry of its webs, the team decided to name it after the “Lady Gaga of mathematics.”

The newly discovered spider, Araniella villanii, got its moniker from French mathematician Cédric Villani. Villani, who won math’s prestigious Fields medal in 2010, is known not only for his genius, but also for his sense of style.

The researchers who discovered the neon green spider decided to honor Villani in part because he always wears a spider pin on his lapel. The bright new spider was described Jan. 22 in the journal ZooKeys.

The Khaled bin Sultan Living Oceans Foundation just released a report on the health of coral reefs along the Kingdom of Tonga, a Polynesian archipelago made up of some 170 South Pacific islands. Many of the islands are uninhabited and surrounded by coral reefs. The extensive survey found that those reefs are “moderately healthy,” but the reef fish and the communities of invertebrates are in need of attention.

The scientists found that although the fish species appeared diverse, most were small, with very few large, commercially valuable fish, the researchers said in a statement. The teams also made recommendations, including the education of local fishermen about the importance of specially managed areas, as well as better documentation of fish catch and the fostering of sustainable fishing practices.

Brain balls

Researchers reporting in the journal Science on Jan. 24 have created essentially mini brains, more specifically 3D models showing the development of the human forebrain (the front part of the brain that includes the thalamus and hypothalamus). They created these cool-looking models to study a process involving chromatin, which is the stuff our chromosomes are made of. They also looked at how genes were expressed in the forebrain. Their results mapped out the genetic risk of neurodevelopmental disease in certain cells during development.

Archaeologists used to unwrap Egyptian mummies with much fanfare in front of crowds, a stunt that destroyed cultural history and disrespected the deceased individual. Now, researchers can use computed tomography (CT) scans to noninvasively learn about mummies without literally unwrapping them.

Here is a look at the science behind “Mummies,” an exhibit about Peruvian and Egyptian mummies that runs from March 20 until Jan. 7, 2018, at the American Museum of Natural History in New York, and then returns to the Field Museum of Natural History in Chicago.

Egyptians used mummification to honor the dead and guarantee the deceased’s spirits and bodies were reunited in the afterlife.

More ancient

Mummification was used in many more areas than only Egypt. The exhibition presents preserved remains that come from South American cultures and were created at least 1,500 years prior to those from Egypt.

Complexity perfected

The Chancay culture practiced pit burials. In this exhibit, a life-size example shows how the entire extended family would have been buried together. Living family members could access the site to provide food and drink for the deceased loved ones. This access also meant mummies could be involved in festivals and special events with the living.

Corn beer

Mummies in the Chancay culture found in present-day Peru were often buried with pots filled with “chicha,” or beer made from corn. The Chancay would often refill food and drink offerings for their loved ones.

Jaguar jar

Egypt and parts of Peru may have similarly dry desert climates, but mummification in the regions is notably different. The differences are likely connected to the beliefs about the practice. “Mummies” explores the similarities as well as the differences between the cultures, societies, environments and burial traditions.

Canopic jars

These limestone jars carved with representations of the four sons of Horus were designed to hold the organs of the dead. The symbols of the four deities were carved upon removable lids and were placed to protect the organs and serve the dead through the afterlife.

In touch with history

Millions of animal mummies have been discovered in cemeteries. Archaeologists explain that these were not pets, but rather offerings to Egyptian gods who were associated with specific animals.

Shawabti

Items buried with mummies in Egyptian tombs provided for the dead in the afterlife. Wealthy Egyptians were buried with servants represented by figurines called shawabti. Preferably a year’s worth of servants along with 36 overseers, one for each Egyptian week, were supplied as well.

Unique offerings

At the “Mummies” exhibition, guests can tour a life-size burial from 26th-Dynasty Egypt. This represents a time when Egyptians explored their own past, reviving early traditions of art, architecture and tomb design.

Decorative coffins

Coffins from the 26th Dynasty era tended to have much more decoration, hearkening back to previous times. The hieroglyphs on this coffin were inspired by “The Book of the Dead,” a series of texts believed to help a person traverse the underworld and find the afterlife.

Made to order

Using hieroglyphics, Egyptian coffins were often personalized to the deceased. The individual’s name as well as the gods assisting in that person’s journey were engraved on the coffin.

Details

A coffin from Egypt’s 25th or 26th Dynasty has much detail. The deceased man is shown being assisted by Thoth, the ibis-headed god; Osiris, the god of the underworld; and Anubis, the jackal-headed god.

Modest provisions

Wealthy Egyptians imported materials for their coffins, but less fortunate citizens used scarce, native trees to create their coffins. This painted coffin bears the marks of time with its red paint faded and worn, exposing the simple construction and wood grain.

Morphing culture

A massive burial ground holding the remains of several high priests of ancient Egypt, along with their assistants, has been discovered in the northern part of the site of Tuna el-Gebel, Egypt’s antiquities ministry announced Thursday (Jan. 30).
So far, the archaeologists have unearthed 20 stone sarcophagi (coffins) made of a “very good quality of limestone” in the burial ground, which lies about 170 miles (270 kilometers) south of Cairo, said Mostafa Waziri, the general secretary of Egypt’s Supreme Council of Antiquities, during a news briefing.

In addition, the burials together contained some 700 amulets, some made of gold or precious stones, along with more than 10,000 shabti figurines made of faience (a glazed ceramic), Waziri said. The ancient Egyptians believed that shabti figurines served the deceased in the afterlife.

The archaeologists said they aren’t sure how many mummies are buried at the site. But given that many of the stone sarcophagi have yet to be opened, it is likely that many will be discovered, the researchers said.

“Excavations are still running. We expect to find more and more and more [discoveries] in this area,” Waziri said.

Egypt’s Late Period

The high priests buried at the site date to what archaeologists call the “Late Period,” a time when ancient Egypt was often struggling to achieve independence from foreigners, including the Nubians, Assyrians and Persians. The earliest Late Period burials found to date are from the 26th dynasty (688 B.C. to 525 B.C.), a time when Egypt had regained its independence after the Nubians had ruled it.

The Late Period ended in 332 B.C., when the armies of Alexander the Great entered Egypt. After the death of Alexander, in 323 B.C., the descendants of Ptolemy I (one of Alexander the Great’s generals) ruled Egypt for almost three centuries, until the Romans took over the country in 30 B.C.

Though foreign powers often controlled the country, Egyptian religion continued to thrive. The various foreign rulers, including Roman emperors, tended to respect Egypt’s ancient religious traditions.
