We summarize the week's scientific breakthroughs every Thursday.
- Animals
For jaguars, armored prey is no obstacle
With big heads, thick teeth and strong muscles, jaguars have evolved to take on dangerous prey, often animals covered with thick armor.
- Anthropology
Two groups spread early agriculture
The Fertile Crescent was a diverse place. Multiple cultures were involved in the dawn of farming.
- Paleontology
Why the turtle got its shell
Fossil evidence suggests that turtles’ ancestors started to form precursors to today’s shells to help them dig, not to protect themselves.
- Health & Medicine
Still mysterious, aging may prove malleable
Our editor in chief discusses the science of aging.
- Life
A healthy old age may trump immortality
Despite disagreements about what aging is and isn't, scientists have reached a radical consensus: It can be delayed.
- Neuroscience
The brain’s blueprint for aging is set early in life
The brain's decline may mirror its beginning, offering clues to aging.
- Animals
Organisms age in myriad ways — and some might not even bother
There is great variety in how animals and plants deteriorate (or don’t) over time.
- Animals
Readers mesmerized by ‘Strange visions’
Animal vision, ice-making microbes, brain maps and more reader feedback.
- Animals
What animals’ life spans can tell us about how people age
The animal world can offer insights into human longevity.
- Animals
When bird populations shrink, females fly away
In small and shrinking populations of willow warblers, males outnumber females. That’s because girls choose to join bigger groups, a new study finds.
- Animals
How snails breathe through snorkels on land
Shells with a tube counterintuitively sealed at the end have hidden ways to let Asian snails snorkel while sealed in their shells.
