Portraits of a planet

For centuries, we could glimpse the curvature of Earth from mountain peaks but the only way to ‘see’ our planet whole was through globes and maps. Then our world view changed. Not long after the end of the Second World War, scientists began experimenting with captured German V-2 rockets. They replaced the V-2 warheads with cameras and launched the rockets into near-Earth orbit, capturing the first images of Earth from space. These became the first in a series of iconic portraits that changed our relationship with our planet. In this Nature Video we celebrate these awe-inspiring images, including Earthrise, The Blue Marble, Pale Blue Dot and more.

Migration

A special episode featuring three pieces on migration and research. In this podcast, the team talk to a Syrian scientist who risked his life escaping his country; ask how climate change might affect migration; and look at the pros and cons of letting a computer decide who can enter a country.

CRISPR: Gene-editing and beyond

The CRISPR–Cas9 system has revolutionized gene-editing, but cutting DNA isn’t all it can do. From turning gene expression on and off to fluorescently tagging particular sequences, this animation explores some of the exciting possibilities of CRISPR.

Backchat: predatory journals, the great barrier reef, and ‘time crystals’

In this episode of Backchat, Nature’s reporters delved into the story of predatory journals offering editorial jobs to ‘Dr Fraud’ — a fictional, unqualified academic. They also looked at how the Great Barrier Reef is in hot water, and the perils of explaining 'time crystals' …

The first Americans: Clues to an ancient migration

An archaeological site in California may have opened up a whole new chapter in the history of humans in the Americas. Researchers claim the site shows evidence of humans interacting with the bones of a mastodon, an ice age relative of elephants and mammoths. New dating suggests the site may be 130,000 years old — 100,000 years earlier than the accepted date for the first human colonization of the Americas.

Duck-like-dinos and exoplanet geology

A much-travelled fossil with some rather novel features offers researchers a glimpse of a semi-aquatic dinosaur with some distinctly duck-like features. Plus geologists talk the next steps studying distant worlds.

Cat domestication: From farms to sofas

Years before they conquered the Internet, cats colonized our sofas. But they haven’t spent the past 10,000 years just snoozing. A study reveals that tamed cats swept through Eurasia and Africa carried by early farmers, ancient mariners and even Vikings. The researchers analysed DNA from more than 200 cat remains and found that farmers in the Near East were probably the first people to successfully tame wild cats 9,000 years ago, before a second wave of cat domestication a few thousand years later in ancient Egypt.

Matter’s mirror image, the first flower, and editing embryos

This episode looks at the first US-based experiments to edit the genome of a human embryo, learns about researchers hunting for differences between matter and antimatter, and investigates what the common ancestor to all flowers might have looked like.

Paper and string: the DIY centrifuge

A centrifuge is a crucial piece of kit for hospitals and labs across the world. But what if you could make one out of paper and string? The ‘paperfuge’ is the cheapest and fastest hand-spun centrifuge ever designed — and it can reach speeds of up to 125,000 revolutions per minute. Nature Video reveals how this invention will allow basic diagnostic tests in areas without laboratory resources or electricity.

Food security

As part of our Grand Challenges series, we spoke to three experts on agriculture, asking how we can grow enough food for an increasing global population.
