After analyzing the mitochondrial genome, the team discovered that the island-dwelling elephant is the descendant of straight-tusked elephants and was possibly isolated on Sicily between 50,000 and 175,500 years ago.

Ancient Elephants the Size of Shetland Ponies Once Roamed Sicily

The animals' size reduction is comparable to if humans were to shrink down to the size of a rhesus monkey

Data collected revealed that a neutron star twice as massive as the sun was swallowed up by a black hole nine times the size of the sun.

Researchers spotted both events using sensors to locate ripples in spacetime that traveled 900 million years to reach Earth

The supernova SN2018zd (large white dot on the right) located 30 to 40 million light years away was first identified in 2018 and may be the first observed evidence of an electron-capture supernova.

First Observed Nearly a Thousand Years Ago, Scientists Finally Confirm Elusive Third Type of Supernova

The stellar explosion may explain an odd event documented by Chinese astronomers in 1054 C.E.

On June 27, residents flocked to the Clackamas River at High Rocks Park in Portland, Oregon, to take a dip and enjoying some cliff jumping.

Heat Dome Scorches Pacific Northwest With Record-Breaking High Temperatures

Cities in Oregon and Washington have surpassed 100 degrees Fahrenheit for several consecutive days

Out of the 900 baby lizards created by breeding Mr. Frosty (pictured above) with various other leopard geckos, 80 percent developed tumors before they were five years old.

This Gecko Named Mr. Frosty and His 900 Babies May Inspire Human Skin Cancer Treatments

A genetic mutation linked to melanoma in humans gives the lizards their lemony-hue—and triggers tumor growth on their scaly skin

Currently, Tasmanian devils are listed as endangered on the IUCN Red List of Threatened Species.

Tasmanian Devils Wipe Out an Entire Colony of Little Penguins

The marsupials were brought to the island in a conservation rebound effort. Instead, they decimated native bird populations

The bright red regions were thought to be caused by molecules known as tholins, or organic compounds that rain down onto the surface after cosmic rays or ultraviolet light interact with the methane in Pluto's surface and atmosphere.

Pluto's Red Patches Are Mystifying Scientists

A new study suggests there's more to the dwarf planet's rust-colored deposits than meets the eye

Currently, single-use plastics lose 95 percent of their value after use, causing a $110 billion loss to global markets every year.

Plastic Waste Can Be Transformed Into Vanilla Flavoring

Researchers used microbes to convert plastic waste into the chemical additive

Cosmetics designed to stay on longer or marketed as "wear-resistant," "long-lasting," and "waterproof" contained the highest levels of PFAS.

Scientists Find Toxic 'Forever Chemicals' in More Than 100 Popular Makeup Products

Waterproof mascara and long-lasting lipsticks contained the highest levels of organic fluorine, an indicator of PFAS

Based on the size of the skull, the research team also found that the rhino had a long thick neck, a short trunk similar to that of a modern-day tapir, and a deeper nasal cavity.

This Prehistoric Giant Rhino Was 'Taller Than a Giraffe'

The prehistoric mammal had a 3.8-foot-long head and stood at about 16 feet tall

The newly deciphered genome, T2T-CHM13, added 200 million base pairs to the 2013 version of the human genome and found 115 new genes.

Scientists Are on the Cusp of Finally Deciphering the Entire Human Genome

After 20 years of work, the pursuit is nearly complete, but the team still has to sequence a Y chromosome

While observing the crayfish, the research team saw that the crustaceans exposed to low levels of the antidepressant were more adventurous and twice more likely to pop out of their shelters and explore their surroundings.

Crayfish Exposed to Antidepressants Are More Adventurous

While the traces of drugs found in waterways alter the crustacean's behaviors, it may leave them more vulnerable to predation

Sometime between 30-40 seconds after the diver was swallowed, the whale began to move its head from side to side and then resurfaced.

A Cape Cod Lobster Diver Was Swallowed by a Humpback Whale—and Then Spat Back Out

Except for severe bruising and a dislocated knee, the survivor is in good health and ready to return to work, he says

The snow’s red hue may also create a ‘snowball’ effect that harms ecosystems because red-tinged snow does not reflect as effectively as white snow and will melt faster.

What 'Glacier Blood' on the French Alps Tells Scientists About Climate Change at High Elevations

The red hue is produced by snow algae blooms. The color most likely shields the algae from damaging ultraviolet rays

The Southern Ocean is defined by a swift undertow called the Antarctic Circumpolar Current (ACC) that flows from West to East around Antarctica.

National Geographic Officially Recognizes the Southern Ocean as World's Fifth Ocean

The organization's cartographers will now label a total of five oceans on their maps and atlases

Tinier whales threaten the species’ survival because smaller whales do not have as many offspring.  Nursing mothers who entangle themselves in nets also produce smaller calves.

Humans, We've Shrunk the Whales

North Atlantic right whales born today are three feet shorter on average than whales born in 1980—and commercial fishing could be to blame

Using growth layers on the bear's skull, the researchers dated the remains at 35,000 years old and concluded that the cave bear was an adult around ten years old when it died.

This 35,000-Year-Old Skull Could Be the First Evidence of Humans Hunting Small Cave Bears

The hole in the specimen may have been from injuries inflicted with a spear or during a postmortem ritual

It took over a decade to identify the dinosaur bones because of the remote location of the bones, the fragile state they were in, and their massive size and weight that at times require a forklift to move.

Two Farmers Found the Largest Dinosaur Ever Unearthed in Australia

The long-necked herbivore's length measured the span of a basketball court, stood at two stories, and weighed an estimated 70 tons

Streaked across Ganymede's surface are bright light-colored regions of ridges and grooves that overlap darker-colored terrains along the icy shell. The textured scar-like areas suggest that the moon's surface underwent extreme geologic changes over time.

NASA's Juno Space Probe Zooms by Largest Moon in the Solar System

The flyby will be the closest any spacecraft has flown near Ganymede in over two decades

While most open ocean sharks disappeared after the event, coastal sharks survived, and today's sharks most likely ascended from the survivors.

A Puzzling Extinction Event Almost Wiped Sharks Out of Existence 19 Million Years Ago

Sediment cores show that shark populations declined by 90% during the Miocene, but no one knows why
