The new study compared 1,131 children between 12 and 15 years old who received two doses of the Pfizer-BioNTech vaccine, and 1,129 who received two doses of a placebo.

Pfizer-BioNTech Vaccine Is Highly Effective at Preventing Covid-19 Infections in Adolescents

In a study of 2,260 children age 12 to 15, no vaccinated kids contracted the virus

Captive lemurs receive an abundance of food year-round, so the need to hibernate as a way to store energy when resources are scarce is not needed.

How Studying Lemur Hibernation Could Make Long-Distance Space Travel Easier One Day

As humans’ closest hibernating relative, learning from the critters could also make emergency surgery safer and inform metabolic disease research

Grasshoppers swarm a street light a few blocks from the Las Vegas Strip on July 26, 2019.

Las Vegas Was Inundated by 46 Million Grasshoppers on a Single Night in 2019

A new study says the horde of insects was drawn to the Vegas Strip by its famously bright lights

The Ingenuity helicopter is scheduled to attempt flight this week no later than April 8 after the Mars rover completes its first mission of transporting the small chopper to a flat "airfield" free of obstructions.

Secured under Ingenuity’s solar panels is a stamp-sized swatch of fabric from the Wright Flyer

This is an atomic clock that uses the predictable frequency of ytterbium atoms absorbing and emitting light to tell time. A new experiment paired a ytterbium-based atomic clock with two others that used aluminum and strontium atoms, respectively, to create an even more accurate measure of time.

New Research

New Atomic Clocks May Someday Redefine the Length of a Second

Researchers used three atomic clocks to measure time accurately down to the quadrillionth of a percent

NOAA’s Weather Forecasting System Just Got a Major Update

The new version of the Global Forecast System could give Americans in the path of a hurricane an additional 36 hours to prepare compared to the old model

Bears with intensifying symptoms either die or are require euthanasia. Those that survive require lifetime treatments and can't return to the wild.

A Puzzling Brain Disease Is Killing Black Bears in the Western United States

Some animals showing signs of a neurological disorder had brain inflammation, but the cause is still unknown

This Insect Has Plant DNA in Its Genome

Whiteflies have a gene only found in plants that appears to allow the tiny insects to withstand plants’ chemical defenses

By the time sauteur d’Alfort rabbits are a few months old, they learn how to walk on their front paws to accommodate their uncoordinated back legs.

After five weeks of development, a human brain organoid (left) is roughly twice the size of those from a chimpanzee (top right) and a gorilla (bottom right).

New Research

Experiments Find Gene Key to the Human Brain’s Large Size

The single gene identified by the study may be what makes human brains three times larger than our closest great ape relatives at birth

"Active sleep" only lasted 40 seconds but cycled after 30 to 40 minutes of "quiet sleep". These patterns are similar pattern to how mammals experience rapid eye movement (REM) sleep.

Like Humans and Mammals, Octopuses May Have Two Stages of Sleep

Scientists do not know if octopuses dream in color, but they do change color while sleeping

Damages wrought by climate change and deforestation have transformed the Amazon rainforest. New research suggests the changes to this icon of the natural world caused by human activity may mean the Amazon now emits more greenhouse gases than it absorbs.

New Research

The Amazon Rainforest Now Emits More Greenhouse Gases Than It Absorbs

Climate change and deforestation have transformed the ecosystem into a net source of planet-warming gases instead of a carbon sink

Bald eagle populations have been steadily recovering since their all-time low in the 1960s when fewer than 500 nesting pairs were left.

Planet Positive

Why Bald Eagle Populations Soared in the Last Decade

In 1963, only 417 breeding pairs remained, but 71,400 active couples were recorded as of 2019

Hawai'i's location in the subtropical Pacific makes it susceptible to northeast trade winds that bring infrequent rain showers with clear skies in-between that create optimal rainbow viewing conditions.

Hawai’i Is Officially the Best Place on Earth to See Rainbows, According to Science

The geographic location and topography of the islands create beautiful views

The juvenile walrus spent two days resting in Pembrokeshire, Wales before returning to sea.

How Did This Walrus Get to Wales?
