We summarize the week's scientific breakthroughs every Thursday.
- Neuroscience
Your dog’s brain doesn’t care about your face
Comparing brain scans of people and pups shows that faces hold no special meaning to the brains of dogs, a new study suggests.
- Health & Medicine
Hepatitis C discoveries win 2020 Nobel Prize in physiology or medicine
The 2020 medicine Nobel recognizes work that found that a novel virus was to blame for chronic hepatitis and led to a test to screen blood donations.
- Paleontology
Cannibalism in the womb may have helped megalodon sharks become giants
The ancient sea terror Otodus megalodon may have grown to at least 14 meters long thanks to a firstborn pup’s predatory behavior, some researchers say.
- Animals
This snake rips a hole in living toads’ stomachs to feast on their organs
A particularly gruesome way to kill may help small-banded kukri snakes avoid toxins secreted from the neck and backs of some toads.
- Life
A new map shows where Asian giant hornets could thrive in the U.S.
Suitable habitat along the Pacific West Coast means so-called “murder hornets” could get a foothold in North America if they aren’t eradicated.
- Life
Before migrating, some blue whales switch up the timing of their songs
Pacific blue whales change the daily timing of their songs ahead of migration, helping scientists better anticipate these massive animals’ movements.
- Environment
Invasive jumping worms damage U.S. soil and threaten forests
Also known as snake worms, these writhing wrigglers turn forest leaf litter into bare ground, changing soil composition and ecosystems as they go.
- Neuroscience
Tiny, magnetically controlled robots coax nerve cells to grow connections
Research using microrobots and nerve cells from rats could point to new treatments for people with nerve injuries.
- Ecosystems
Trapped under ice, light-loving algae grow in the dark Arctic winter
Blocked off from nearly all light beneath a thick layer of ice and snow in the winter, marine phytoplankton in the Arctic still find a way to thrive.
- Space
Hope for life on Venus survives for centuries against all odds
Early scientists often assumed that Venus, though hotter than Earth, hosted life.
- Life
Life on Earth may have begun in hostile hot springs
What researchers learn at hot springs and seafloor vents may guide the search for life on icy moons and Mars.
- Animals
A beaked whale’s nearly four-hour-long dive sets a new record
The animals may rely on large stores of oxygen, a slow metabolism and the ability to tolerate lactic acid to go for hours without surfacing for air.
