A blue moon in 2015

A Smaller Than Usual Blue Moon Will End the Month With a Lunar Spectacle. Here’s What to Know About the Full Micromoon

The blue moon will be the second of two full moons in the same month, a coincidence that only takes place about every two and a half years. It will also appear to be slightly smaller and dimmer than the average full moon

A large hailstone made up of an aggregate of smaller ice particles

Giant, Destructive Hail Is Becoming More Common With Climate Change, Study Says

As the atmosphere warms, the potential for hail as large as a grapefruit is growing

A female blue crab with an acoustic telemetry tag on its shell. Scientists at the Smithsonian Environmental Research Center use telemetry tags to track the migration of blue crabs throughout the Chesapeake.

Young Blue Crabs Have Been Mysteriously Dwindling in the Chesapeake Bay for Years. This Winter, They Saw a Boost in Numbers. What’s Driving These Trends?

A recent report detailed a 50 percent drop in juvenile Chesapeake blue crabs since 2010. Then, a survey found a surprising surge in the young crustaceans this year

NASA Unveils New Details About the Future Moon Base and the Missions Laying the Groundwork to Build It

The first three missions are targeted to launch this year. They’ll involve lunar landers developed by several aerospace companies, including Blue Origin, and deliver scientific instruments and a rover

Scientists carried out their experiments in the bacterium Escherichia coli. Cells of the species are artificially colored blue in this microscope image.

Scientists Used A.I. to Redesign a Microbe’s Machinery to Function Without a Key Ingredient of Life

Although the researchers did not create an entire cell that could function without a crucial building block, the findings represent a big step in synthetic biology and provide a glimpse at how Earth’s earliest organisms may have lived

In February 2020, naturalist guides Lizardo Proaño and Juan Carlos Narváez photographed a harvestman eating a live frog during a night hike at Mashpi Lodge in Ecuador.

Daddy Longlegs Seem to Hunt Frogs in South America, Revealing the Gangly Arachnids as Overlooked Predators

A new study suggests that harvestmen actively attack the slippery amphibians, rather than just scavenging them. The findings hint that the spineless creatures have a more complex relationship with vertebrates than previously thought

Western Australia’s Ningaloo coast

Scientists Detect an Elusive Giant Squid and Many Other Surprising Marine Animals Near Western Australia Thanks to DNA in the Water

Mucus, feces, skin and other shed tissue allowed researchers to investigate which creatures have been swimming in two deep-sea canyons without having to observe or catch them

A Sudden Landslide Triggered Alaska’s 2025 ‘Mega-Tsunami.’ Now, Scientists Have Identified Warning Signs to Predict Similar Events

Natural disasters like the one at Tracy Arm fjord, about 45 miles south of Juneau, could become more common as climate change alters frigid landscapes, according to researchers

Human development—such as roads—affects wildlife. But so does the presence of people.

The Mere Presence of Humans—Not Just Our Changes to the Land—Can Alter Wild Animals’ Behaviors, a New Study Suggests

Researchers examined GPS tracking data from thousands of animals representing 37 species and anonymized cellphone location data from 2020, a year of Covid-19 lockdowns, and the previous year

Paleontologists Discover an Ancient Marine Reptile They’ve Dubbed the T. Rex of the Sea, Crowning Another King of the Cretaceous

Scientists figured out that the predators were lumped in with a previously named mosasaur species. The new one, called Tylosaurus rex, could grow to 43 feet long, about the length of a school bus

As the Psyche spacecraft approached Mars from its night side, the red planet looked like a crescent.

The Psyche mission, on its way to study an asteroid of the same name, approached within 2,864 miles of the red planet on May 15

The drug ensitrelvir, under the brand name Xocova, was recently approved in Japan as a post-exposure protection against Covid-19.

This Pill Can Prevent You From Getting Covid-19 After Exposure to the Disease-Causing Virus, According to a Clinical Trial

The drug showed promising results in an international study involving nearly 2,400 participants, and the U.S. Food and Drug Administration is expected to make an approval decision for it in June

The researchers studied four captive belugas housed at the New York Aquarium of the Wildlife Conservation Society.

Belugas Can Recognize Themselves in Mirrors, Joining a Short List of Nonhuman Species That Show Signs of Self-Awareness

The researchers hope that this new understanding of cognition in the toothed whales will increase human empathy and concern for the animals, leading to more efforts to protect them

Neptune, which appears blue because of methane in its atmosphere, has a strange set of moons.

Neptune’s Moon Nereid Might Be the Sole Intact Survivor of an Ancient Lunar Collision

A study suggests that the ice giant’s largest moon, Triton, made a dramatic entrance to the Neptunian system long ago, kicking Nereid outward and destroying the planet’s other original lunar companions

Around 90 percent of people are right-handed.

Why Is Nearly Every Person Right-Handed—but Not Every Ape and Monkey? New Research Explores the Evolutionary Origins of Human Handedness

Brain size and bipedalism are the most likely drivers of our species’ right-hand dominance, according to new research

Groundbreaking DNA Analysis Identifies 1.3 Million Living Relatives of Colonial Maryland’s Earliest Settlers

Experts compared DNA from 49 skeletons buried in a cemetery in St. Mary’s City to genetic data shared by 11.5 million 23andMe users. They also identified what may be the remains of the colony’s second governor

Mediterranean monk seals are among the rarest pinnipeds in the world.

Mediterranean Monk Seals Hide in Underwater ‘Bubble Caves’ to Avoid Tourists During the Busy Summer Season, a Study Suggests

Researchers caught the rare pinnipeds resting and sleeping in a secluded chamber on the Greek islet of Formicula. The findings suggest that these small caves should be included in efforts to protect the animals’ habitat

Researchers collected groundwater in boreholes up to 1.8 miles underground. The water contains dissolved natural hydrogen.

This Canadian Mine Might Release Enough Natural Hydrogen Each Year to Power 400 Homes, Hinting at an Untapped Source of Clean Energy

Many of the country’s metal mines are embedded in an ancient rock formation that probably also houses a lot of the resource, referred to as “white hydrogen”

Gentoo penguins have been considered a rare beneficiary of climate change due to their population growth on the Antarctic Peninsula. Splitting the birds into four species brings to light regional threats and declines.

Gentoo Penguins Are Actually Four Different Species, Scientists Say, Revealing They’re Not Quite ‘Winners’ of Climate Change After All

A new study indicates that the adaptable birds evolved into distinct lineages as isolated populations shifted to match their environmental conditions over time. The work has implications for how conservationists assess threats to gentoos

Tuerkayana hirtipes, a true crab species examined in the study

When Did Crabs Evolve Their Iconic Sideways Scuttle? Scientists Traced It to a Common Ancestor That Lived 200 Million Years Ago

The findings suggest that their famous lateral movement evolved just once. It may have helped the animals rapidly spread and diversify because moving in two directions meant they could easily escape predators
