We summarize the week's scientific breakthroughs every Thursday.

Ancient humans may have deliberately voyaged to Japan’s Ryukyu Islands
Satellite-tracked buoys suggest that long ago, a remote Japanese archipelago was reached by explorers on purpose, not accidentally.

The ‘last mile’ for COVID-19 vaccines could be the biggest challenge yet
The need for cold storage and booster shots could create problems for distributing coronavirus vaccines to nearly everyone in the world.
- Health & Medicine
The U.K. is the first country to authorize a fully tested COVID-19 vaccine
Pfizer will deliver the first of 40 million doses of its coronavirus vaccine promised to the United Kingdom in the coming days.
- Health & Medicine
Health care workers and long-term care residents should get COVID-19 vaccines first
With an initial 40 million doses of the vaccines, enough for 20 million people, anticipated by year-end, health officials are setting priorities.
- Health & Medicine
Long-lasting shots work better than daily pills to prevent HIV in at-risk women
A more discreet HIV prevention method — a shot once every eight weeks —could help to boost use in women at risk.
- Health & Medicine
Coronavirus shutdowns don’t need to be all or nothing
Governments are implementing more targeted restrictions like limiting restaurant capacity to slow a fall surge. Research suggests they could work.
- Health & Medicine
The FDA has approved the first drug to treat the rapid-aging disease progeria
Children with a rare genetic disorder called progeria age quickly and often die before they are 15. A newly approved drug may give them more time.
- Health & Medicine
Immunity to COVID-19 may persist six months or more
Even after recovery, the body continues to improve its antibody response to the coronavirus — perhaps thanks to viral bits hiding in the intestine.
- Health & Medicine
Oxford and AstraZeneca say their COVID-19 vaccine works too
A third major vaccine, which may be easier to distribute than others, appears to prevent disease and maybe transmission of the coronavirus.
- Neuroscience
Lonely brains crave people like hungry brains crave food
After hours of isolation, dopamine-producing cells in the brain fire up in response to pictures of humans, showing our social side runs deep.
- Archaeology
The biblical warrior Goliath may not have been so giant after all
Archaeological finds suggest the width of the walls of Goliath’s home city were used to metaphorically represent the Old Testament figure’s height.
- Health & Medicine
Here’s why COVID-19 vaccines like Pfizer’s need to be kept so cold
Both Pfizer and Moderna built their vaccines on RNA. Freezing them keeps their fragile components from breaking down.
