Alfie and Bailey, the first dogs whose genes were edited so they lack the allergy-inducing protein Can f 1.

Allergic to Dogs? These Gene-Edited Beagles Could Pave the Way to Your Dream Canine Companion That Won’t Trigger Sniffles

Geneticists altered Alfie and Bailey’s DNA so that they don’t produce a major allergen. However, canines like them are not currently commercially available, and some experts express ethical concerns about altering the animals’ genes

The new study examined Mars' gravitational field to infer its interior structure.

Mars’ Southern Half Is Weirdly Warm Underground. The ‘Thermal Anomaly’ Might Explain Why the Planet’s Hemispheres Look So Different

Researchers used a novel technique to figure out what’s going on inside the Red Planet. The work suggests that the interior of the southern hemisphere is hundreds of degrees hotter than that of the northern hemisphere and partially molten

Would You Eat a Cookie Made From Upcycled Plastic? Scientists Propose a New Way to Deal With Waste and Provide Food in Extreme Environments

A team of researchers programmed yeast to turn broken-down plastic and agricultural waste into sweet treats called µBites. They might come in handy during deep-space missions or in disaster zones, although some critics say the food is impractical

Many stars orbit the Milky Way's central supermassive black hole. But S301's orbit, shown in red, is the only one known to be close enough to feel the effects of the black hole's theorized spin.

This Star Orbits Our Galaxy’s Heart at a Record-Breaking Speed—and Could Help Uncover Secrets About the Behemoth Black Hole There

The speedster travels at up to 56 million miles per hour, or about 8 percent the speed of light. It also gets very close to the supermassive black hole at the center of the Milky Way

The studied species, brown-lipped snails, are native to Europe.

Snails Can Make Their Slime Sticky, Slippery, Foamy or Hard Depending on Their Needs. Here’s How They Tweak Their Multipurpose Mucus

The critters can alter the proportions of calcium and collagen in the versatile substance, which changes the protein structure. The different textures can help snails glide, climb or protect themselves

Paleontologists Discover a New Species of Ice Age Toad at the La Brea Tar Pits, Offering Clues About the Area’s Ancient Climate

The fossilized remains, recovered in 1929, were part of La Brea’s relatively understudied amphibian collection. Since toads are cold-blooded and sensitive to environmental changes, the discovery can help researchers piece together past climate conditions

The deep partial lunar eclipse will peak on August 28 at 12:13 a.m. Eastern time.

Turn Your Eyes to the Night Skies This Week to See a Near-Total Lunar Eclipse. It’ll Temporarily Turn the Moon Red

During the peak, 96 percent of the moon will be within the darkest part of our planet’s shadow. The orb will take on an eerie glow because of how sunlight gets filtered through Earth’s atmosphere

In Pompano Beach, a museum dedicated entirely to jellyfish has recently opened its doors. 

‘Only One of Its Kind’ Jellyfish Museum Astounds Visitors With Awe-Inspiring Displays of Sea Nettles Safely Behind Glass

The museum opened in the spring and was founded by two aquarium experts who fled the Russia-Ukraine war

The team combined two operating tables to hold the snake's lengthy 110-pound body.

This 15-Foot Python Is the First Known Snake to Receive Electrochemotherapy for Cancer. Now, She’s Officially Free of the Disease

The pioneering treatment makes it easier for traditional chemotherapy drugs to penetrate cancer cells. After the procedure, the reptile, named Jodie Foster, made a speedy recovery

NASA-Funded Mission to Rescue a Falling Space Telescope Officially Ends in Failure

The commercial LINK spacecraft was supposed to give NASA’s Swift observatory a boost, pushing it higher into orbit to extend its life. But after launch, LINK experienced several problems. Swift is expected to re-enter Earth’s atmosphere and burn up by the end of this year

Narwhals live in the North Atlantic and Arctic Oceans.

Narwhals Sport Iconic Straight, Spiraled Tusks. Scientists Just Uncovered Some of the Eye-Catching Feature’s Structural Secrets

The Arctic whales are the only known animals with straight tusks, and ones that consistently twist to the left. New research reveals that the inner layer twists to the right and that the opposing spirals provide strength and help the tusks grow straight

These Coral Reefs Off West Africa Were Long Presumed Dead. Scientists Just Found Them Alive and Teeming With Life

Fish surveys in the 1960s detected what experts thought was a dead coral reef barrier off the country of Benin. Decades later, researchers set off in small fishing boats to investigate it using sonar mapping, underwater drone surveys and stationary video recorders

When Did Animals Start Giving Birth to Live Young? This 236-Million-Year-Old Fossil Might Rewrite Mammals’ Evolutionary History

A bone feature found in a mammal ancestor hints that the creature was relatively large as a newborn, more in line with the size of a creature birthed live than hatched from an egg. Still, it provides only indirect evidence

Astronomers Peered at the Early Universe and May Have Discovered a New Kind of Celestial Object: Black Hole Stars

Since the James Webb Space Telescope started collecting data in 2022, it has found puzzling objects dubbed little red dots. A new study suggests they might be giant black holes with some characteristics of stars

Streaks of light from Venus and satellites

An Aerospace Startup Just Got Approval to Test Beaming Sunlight to Earth. Here’s Why Experts Are Worried—and Petitioning

By 2035, Reflect Orbital aims to launch up to 50,000 satellites equipped with mirrors to provide sunlight to Earth-based solar panels. Critics are concerned about impacts on wildlife, astronomy research and human health

An artistic conception of one of the Voyagers speeding through space

NASA Completes Daring ‘Big Bang’ Fix on the Voyager 2 Probe, Allowing It to Keep Studying Interstellar Space

Scientists swapped three of the probe’s heating devices for ones that use less energy, and they might do the same with Voyager 1. Both spacecraft launched almost 50 years ago

A saber-toothed cat skull found at the La Brea Tar Pits

Spinal Deformities in Saber-Toothed Cat Fossils Reveal How the Now-Extinct Felines May Have Spent Their Final Days

Researchers studied saber-toothed cat vertebrae found in the La Brea Tar Pits in Los Angeles. They identified a surprisingly high number of deformations, including signs of spinal nerve tumors, hinting at a dwindling population suffering the consequences of inbreeding

The Falcon 9 rocket's upper stage left its mark on the moon's surface. 

A SpaceX Rocket Part Just Slammed Into the Moon, Creating a Dust Plume and Crater. Here’s What Some Scientific Instruments Saw

The Korea Aerospace Research Institute captured before-and-after images of the impact site, and a telescope in Chile detected signs of the plume. However, no one was able to watch the collision live

Previous research hinted at ghost ancestry in our DNA, but the new work helps pinpoint the timeline of when the ancient relatives' genetic material entered our genomes.

Traces of Two Extinct ‘Ghost’ Ancestors Were Found Hiding in Modern Human DNA, Hinting at Our Extremely Complex Family Tree

Researchers used a new method to investigate past interbreeding with Homo sapiens that doesn’t require ancient DNA. The technique identified areas of living humans’ genomes that came from unknown hominins, including one from a 1.8-million-year-old lineage

Researchers involved in the study collect samples at Blood Falls.

Why Does Antarctica’s Blood Falls Spew Ruby Red Water? Microbes Offer New Clues About the Geologic Feature’s Ancient Origins

The falls contain saltwater rich with iron, which oxidizes and turns red when exposed to air. A new study provides further evidence that the brine probably comes from ocean water trapped when flood waters retreated millions of years ago
