Ocean Sponge Skeletons Suggest a More Significant History of Global Warming Than Originally Thought

Analysis of the sea creatures’ skeletal chemistry suggests the world’s temperatures have increased by 1.7 degrees Celsius since pre-industrial times

An entire neighborhood in Tacloban, Leyte, Philippines, destroyed by Typhoon Haiyan in 2013. More than 6,500 people died during the storm, which had maximum sustained winds of 195 miles per hour. Winds of those speeds would be above the threshold for a hypothetical Category 6 for tropical cyclones proposed by researchers.

Do We Need a Category 6 Designation for Hurricanes?

Global warming is leading to more intense storms well above the threshold for Category 5 hurricanes, scientists write in a new paper

Common clownfish have three white stripes, which they "count" to identify other members of their species as potential threats, a new study suggests.

Clownfish Can ‘Count’ Stripes on Other Fish to Identify Intruders, Study Suggests

Notoriously aggressive, common clownfish may be using basic mathematics to determine if another fish is a friend or foe

The full moon, as seen from Granada, Spain. A new study suggests the moon is shrinking, causing moonquakes that could interfere with planned lunar missions.

The Moon Is Shrinking, Causing Moonquakes at a Potential NASA Landing Site, Study Finds

Though the risk to astronauts is low, the shaking could cause landslides and impact potential long-term settlements at the lunar south pole

The newly discovered tree would have supported a wide crown of leaves over a narrow trunk, scientists say.

Rare Fossil Shows Trees Looked Very Different 350 Million Years Ago

The newly discovered specimen looks like something from the imagination of Dr. Seuss, and it sheds light on a little-understood era of prehistory

The 23 pairs of human chromosomes. People who inherit two tall X chromosomes (bottom right) are much more susceptible to autoimmune diseases than people with one X and one short Y chromosome.

Why Do Women Get More Autoimmune Diseases? Study of Mice Hints at Answers

Four in five people with an autoimmune disease are women. New research points to an RNA molecule involved in silencing one of their X chromosomes as a potential culprit

The Hohle Fels baton, made from 15 pieces of ivory unearthed in 2015.

Stone Age People Used This 35,000-Year-Old Woolly Mammoth Tusk Tool to Make Rope, Scientists Say

To test their hypothesis that the perforated object was a tool, researchers used a replica to create a 16-foot-long rope from cattail reeds

Miniature dachshunds have a median lifespan of 14 years, according to the data.

Which Dogs Live the Longest? Scientists Say Small and Long-Nosed Canines Outlive Others

A new study of more than 500,000 dogs in the United Kingdom adds more nuance to our understanding of their life expectancy based on breed, size, face shape and other factors

A fragment of early human bone uncovered in the excavation in Ranis, Germany

Humans and Neanderthals Lived Side by Side in Northern Europe 45,000 Years Ago, Study Finds

Archaeologists identified bone fragments of prehistoric modern humans in Germany, suggesting several millennia of coexistence with Neanderthals before the species disappeared

A sea otter basks in the water with some kelp. Sea otter populations plummeted as they were killed for their pelts in the 18th and 19th centuries.

Hungry Sea Otters Help Prevent Erosion on California’s Coast

The marine mammals, which were once hunted nearly to extinction, feed on crabs that would make the land more susceptible to erosion by digging holes in the soil and eating roots

A hermit crab wears the top of a broken bottle as a shell.

Hermit Crabs Are Using Trash as Shells Across the World, Scientists Find

Researchers analyzed photographs of the crustaceans online, identifying nearly 400 examples of artificial shells, which were often plastic bottle caps

The archive was found by a direct descendant of Herman Matzinger, the doctor who performed McKinley's autopsy.

Newly Discovered Papers From President McKinley’s Assassination Are for Sale

The archive belonged to Herman Matzinger, who performed the autopsy on the 25th president and conducted a bacteriological analysis to rule out the possibility of poison-tipped bullets

Western monarchs prefer to cluster in areas with little to no wind, high humidity, dappled sunlight and easy access to nectar-producing plants.

Monarch Butterflies Wintering in California Are Down 30 Percent From Last Year

The insects’ population is slowly rebounding from a historic low in 2020, but they remain in crisis, having declined by more than 95 percent since the 1980s

The Millenium Camera, set on the path of a hiking trail in Tucson Arizona, is capturing an image over the course of 1,000 years.

This Camera Is Taking a 1,000-Year-Long Exposure Photo of Tucson’s Desert Landscape

Jonathon Keats, who devised the plan, hopes the camera will inspire onlookers to contemplate how humanity’s actions affect the environment

An image from an electron microscope of Treponema pallidum, the bacteria that causes syphilis. In 2022, the number of reported cases of syphilis in the United States was the highest it has been since 1950.
