We summarize the week's scientific breakthroughs every Thursday.
- Animals
Dolphins can learn from peers how to use shells as tools
While most foraging skills are picked up from mom, some bottlenose dolphins seem to look to their peers to learn how to trap prey in shells.
- Animals
New species of scaly, deep-sea worms named after Elvis have been found
A genetic analysis sheds new light on funky scale worms with glittery, scales reminiscent of sequins on the “The King’s” iconic jumpsuits.
- Space
Stunning images of swirling gas and dust may show a planet forming
Infrared images show a spiral of gas and dust around a star 520 light-years away. A smaller, tantalizing twist hints at where a planet is coalescing.
- Neuroscience
Blind people can ‘see’ letters traced directly onto their brains
Arrays of electrodes can trace shapes onto people’s brains, creating bursts of light that people can “see.”
- Tech
Wiggling wheels could keep future rovers trucking in loose lunar soil
A rover that wriggles through soil could climb hills on the moon or Mars that are too steep for a simple wheeled bot.
- Ecosystems
Tapirs may be key to reviving the Amazon. All they need to do is poop
Brazilian ecologist Lucas Paolucci is collecting tapir dung to understand how the piglike mammals may help restore degraded rain forests.
- Life
Why otters ‘juggle’ rocks is still a mystery
Shuffling pebbles really fast looks as if it should boost otters’ dexterity, but a new study didn’t find a link.
- Planetary Science
This is the most comprehensive map of the moon’s geology yet
Cartographers merged Apollo-era maps and modern lunar observations to into a new geologic map of the moon.
- Health & Medicine
Why 6 feet may not be enough social distance to avoid COVID-19
Scientists who study airflow warn that virus-laden drops may travel farther than thought.
- Physics
Here’s how the periodic table gets new elements
Today’s scientists keep adding to the periodic table. But an element has to earn its spot.
- Climate
The largest Arctic ozone hole ever measured is hovering over the North Pole
A strong polar vortex in early 2020 led to what may be a record-breaking hole in the ozone layer over the Arctic.
- Life
Algae use flagella to trot, gallop and move with gaits all their own
Single-celled microalgae, with no brains, can coordinate their “limbs” into a trot or fancier gait.
