Olive sea snakes are among the largest marine snake species and sometimes make contact with divers.

Venomous Sea Snakes That Charge Divers May Just Be Looking for Love

A new study suggests apparent attacks are actually fleeting cases of mistaken identity

A fox squirrel perched on part of an experiment designed to test its agility and decision-making. Researchers used peanuts to entice the rodents to participate.

In a Spider vs. Snake Battle, These 40 Arachnids Would Defeat and Devour Their Serpentine Foes

At least 40 arachnid species kill and eat certain slithering predators, which can be up to 30 times the eight-legged critters' size

Emperor penguins are the world's largest penguin, standing almost four feet tall and weighing around 88 pounds. They live almost exclusively in Antarctica and need sea ice to survive.

New Research

Climate Change Poised to Push Emperor Penguins to the Brink of Extinction

Study estimates 98 percent of colonies will be quasi-extinct by 2100 unless the world drastically reduces its greenhouse gas emissions

Poland's coal-fired Belchatow Power Station released 38 million tons of carbon dioxide into the atmosphere in 2018.

New Research

Just 5 Percent of Power Plants Release 73 Percent of Global Electricity Production Emissions

Targeting the world's worst emitters could offer disproportionate benefits when it comes to fighting climate change

An adult male transient or Bigg's killer whale.

Stranded Killer Whale Survives With the Help of Humans

The whale was spotted stuck among the rocks of an island in Southeast Alaska, but after about six hours on dry land the whale was able to swim off

A new article suggests that cats have been underutilized in studies of genetic disease and that studying their genomes, which are structured similarly to humans', could yield new treatments.

New Research

Human Genomes Are Surprisingly Cat-Like

Cat genomes are more similar to ours than those of mice and dogs, yet researchers say felines are underutilized in genetic studies of disease

This map shows how land and ocean temperatures have changed from June 2021 relative to the 1951-1980 base period. High values (darker red colors) indicate temperatures that are higher than those in the base period. The number in the top right is an estimate of the global mean temperature increase. All temperatures are in Celsius.

Study Measuring Earth's Vital Signs Warns of Climate Tipping Points

The authors say tropical coral reefs, the Amazon rainforest, and the West Antarctic and Greenland ice sheets may have passed dangerous tipping points

Innovation for Good

Sharks' Intestines Spiral Like a Valve Invented by Nikola Tesla

Tesla's ingenious valve promoted a one-way flow of fluid without the need for moving parts, but, it turns out, evolution got there first

A map from NOAA showing parts of the country that are under heat advisory as of July 27 (orange), excessive heat watch (brown) and excessive heat warning (fuchsia). The shaded areas of the map with heat related advisories or warnings encompass more than 30 million people.

'Heat Dome' Descends on Central United States

Forecasts suggest more than 30 million people could see temperatures topping 100 degrees this week

Researchers extracting an ice core from the Guliya Ice Cap in the Tibetan Plateau in 2015.

New Research

Scientists Extract 15,000-Year-Old Viruses From Tibetan Glacier

Researchers say the ancient pathogens are unlikely to cause humans any harm, but 28 out of the 33 viruses found are new to science

Feral hogs wreak havoc on the ecosystems they invade, and new research suggests they're also contributing to climate change by releasing 1.1 million cars-worth of carbon dioxide every year.

New Research

Feral Pigs Release 1.1 Million Cars-Worth of Planet-Warming Carbon Dioxide Every Year

The study's results add exacerbating climate change to the list of environmental impacts ascribed to this invasive species

This is the 93-year-old Xerces blue butterfly specimen that researchers collected tissue samples from for this study.

New Research

This Butterfly Is the First U.S. Insect to Be Wiped Out by Humans

Genetic tests using museum specimens suggest that the Xerces blue was a distinct species and that it disappeared in 1941

An opah or moonfish that washed up on Sunset Beach in northern Oregon on July 14.

Brightly Colored, 100-Pound Moonfish Washes Up on Oregon Beach

Scientists say this open-ocean species, also known as an opah, typically inhabits warmer waters than those of the Pacific Northwest

New Research

New Black Hole Image Shows Plasma Jets Blasting Into Space

Researchers say the new, detailed image of the black hole at the center of the Centaurus A galaxy could reveal how its jets formed

The aftermath of floods that ravaged the village of Schuld in western Germany, seen on July 16, 2021. The floods killed at least 165 people across western Germany and neighboring countries.

Deadly Floods Rip Apart Western Germany, Claiming at Least 165 Lives

Nearly two months-worth of rain fell in just 24 hours, leading to flash floods that tore through buildings

This wearable sensor harvests sweat from the fingertips to generate the electricity it needs to measure things such as heart rate and blood-sugar.

Innovation for Good

New Wearable Medical Sensors Run on Fingertip Sweat

The slim, flexible device could measure blood glucose or heart rate without the need for batteries

Researchers say that wild plants that gave rise to today’s three lineages of cannabis grew in present-day China.

New Study Suggests Cannabis' Wild Ancestors Likely Came from China

The analysis identifies East Asia as a potential source of genetic diversity for the growing market for medical and recreational marijuana
