Two new studies dig into the long, curving path that cats took toward domestication
Watching metal crystals grow inside liquid metal: Imaging technique could boost hydrogen production
If you dissolve sugar in hot water and then cool it down, you'll see pure sugar crystals form while impurities stay in the liquid. You can even watch the beautiful sugar crystals slowly grow in the water.
'Truly severe' floods overwhelm Southeast Asia
Authorities across Indonesia, Thailand and Malaysia worked on Thursday to reach residents trapped in floods that have killed dozens of people across the region in recent days.
Dating a North American rock art tradition that lasted 175 generations

A U.S.-Russian crew of three began a mission on the International Space Station after being launched there on a Russian spacecraft Thursday.
Survey raises estimate of African forest elephant numbers
DNA pulled from the dung of African forest elephants has given experts a more accurate—and higher—population estimate for the elusive animal, but the species remains critically endangered, a study showed Thursday.
European Space Agency boosts budget to catch up in space race
The European Space Agency said Thursday it would increase its budget for the next three years to almost 22.1 billion euros ($25.6 billion).
Physicists have worked out a universal law for how objects shatter
Whether it is a cube of sugar or a chunk of a mineral, a mathematical analysis can identify how many fragments of each size any brittle object will break into
Emergency response needed to prevent climate breakdown, warn experts
Scientists sounded the alarm on the dire consequences of continued inaction at a briefing in London, warning that we could be heading for "unprecedented societal and ecological collapse"
Scientists capture the crackling sounds of what they believe is lightning on Mars

Mystery foot belongs to ancient human relative: Scientists
Newly discovered fossils prove that a mysterious foot found in Ethiopia belongs to a little-known, recently named ancient human relative who lived alongside the species of the famous Lucy, scientists said Wednesday.
Meteorite samples are time capsules from the early solar system
When a meteor streaks across the sky, it's not just beautiful. It's nature's way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our own, formed.
Warming and droughts led to collapse of the Indus Valley Civilisation
Hotter temperatures and a series of droughts in what is now Pakistan and India fragmented one of the world’s major early civilisations, providing a "warning shot" for today
Instagram users overestimate their social media addiction, study suggests
Instagram users may overestimate the extent to which they are addicted to the platform, according to research conducted on 1,204 U.S. adults published in Scientific Reports. The findings suggest that for most social media users, excessive use is driven by habit rather than
Major droughts linked to ancient Indus Valley Civilization's collapse
Successive major droughts, each lasting longer than 85 years, were likely a key factor in the eventual fall of the Indus Valley Civilization, according to a paper published in Communications Earth & Environment. The findings may help explain why this major ancient
Thousands of genomes reveal the wild wolf genes in most dogs' DNA
Dogs were the first of any species that people domesticated, and they have been a constant part of human life for millennia. Domesticated species are the plants and animals that have evolved to live alongside humans, providing nearly all of our food and numerous other benefits.
Entanglement-enhanced optical lattice clock achieves unprecedented precision
Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.
Scientists warn half the world’s beaches could disappear
Human development and climate-driven sea level rise are accelerating global beach erosion and undermining the natural processes that sustain coastal ecosystems. Studies reveal that urban activity on the sand harms biodiversity in every connected zone, magnifying worldwide
Deadly fungus makes sick frogs jump far, possibly to find mates
Chytrid fungus is a scourge to global amphibian populations, but before it kills some frogs, it can produce symptoms that may help the infected animals find mates and spread the fungus further
