In this excerpt from "This is Life: A Journey from Inside Your Body to Beyond Earth," author and physicist Christophe Galfard explores the way 19th century scientists were starting to use thermodynamics to understand just how old Earth is.
The new Peerium architecture aims to power hyper-efficient computers capable of training AI models with up to 40 trillion parameters.
NASA's Nancy Grace Roman Space Telescope could capture images 30% sharper than — and remain operational for twice as long as — initially expected. Researchers say these "remarkable" developments could greatly enhance the volume and quality of the data they will analyze.
The mission 1.2 billion years of geological history at the Grand Canyon finally has an explanation.
A proposed tabletop quantum sensor could match the precision of the best satellite measurements of frame dragging, a subtle effect predicted by Einstein's general relativity.
Scientists have discovered that a known mushroom, Galerina indica, contains both psychedelic chemicals and deadly toxins.

A fresh look at Einstein's equations suggests that gravity can sometimes snap and reconnect, similar to magnetic field lines on the sun. The findings hint at a new way that gravity and matter can trade energy.

The Nancy Grace Roman Space Telescope is NASA’s newest flagship observatory, launched in August 2026 on a primary 10-year mission to discover tens of thousands of previously unknown exoplanets and to investigate the source of mysterious dark energy.
NASA's Swift Observatory went out in a blaze of glory this week, but it left behind millions of images of the universe that could fuel discoveries for decades.
Live Science readers respond to a recent poll about whether they'd visit the Red Planet even with potential health risks.
The oldest known rock from Mars was discovered on Earth in 2022. Scientists are beginning to reveal its mysteries.
The Middle East is now home to more than two dozen countries and includes the regions along the Mediterranean Sea's southern and eastern coasts, as well as the Arabian Peninsula and neighboring areas along and by the Arabian peninsula. But this region was also once home to some of the world's oldest settlements and civilizations.
Read on to learn about the latest findings from pre-Hispanic to colonial times that tell the stories of people who lived in the Americas long ago.
A DNA analysis has confirmed that a Nazca infant who lived in southern Peru 1,600 years ago had a rare congenital condition called trisomy 13.
In a key coastal area of Peru, violence was low despite the practice of human sacrifice.
This tiny inkwell contains an alphabetic inscription in ancient Etruscan, a language that has never been fully decoded.
The mission 1.2 billion years of geological history at the Grand Canyon finally has an explanation.
A 2019 astronaut photo shows the near-perfect cone of a highly active volcano poking its heavily scarred and partially snow-covered head above a thick bank of low-lying clouds over the Kuril Islands.
In the run-up to the COP31 U.N. climate change conference, scientists have revealed that global carbon emissions from fossil fuels are projected to drop by 0.4% this year, driven by growth in installed wind and solar power capacity, as well as oil price hikes caused by the Iran conflict. But climate goals are still unlikely to be met.
Climate change will fundamentally challenge the world's urban centers. Three cities — San Diego, Milan and Jakarta — offer lessons for how to adapt to a warming planet.
A double subduction zone off the coast of Japan caused rifting halfway around the world to accelerate, fueling the formation of some of North America's most iconic features.
A man's appendix had to be removed, but not for dangerous inflammation, as you might expect.

Neuroscientists say people can be "trained" to recognize when they're dreaming — in other words, lucid dreaming may be an acquirable skill.
A new study points to testosterone and proteins in the skin as reasons why males and females experience temperatures differently.
Madi Allen was 12 years old when she almost died from flu. Now 28, she shared her story with Live Science.
About half of people with long COVID see meaningful improvement in their symptoms after three years, a new study found.
Arachnids are arthropods with eight legs, segmented bodies and no wings. They're generally found on land, and the class includes scorpions, ticks, mites and spiders. There are around 100,000 known arachnid species — about half of which are spiders — but there are likely many more out there yet to be discovered.
Aquatic animals are creatures living in watery environments, including oceans, rivers and lakes. They come in all shapes and sizes, from tiny zooplankton that help form the base of many food webs, up to ocean giants like the colossal squid and the blue whale.
Turtles and tortoises are reptiles with shells on their backs. These shells grow from modified ribs — a trait that likely evolved more than 200 million years ago. Shells are mostly made of bone, with the outer surface covered in scales made of keratin (the same stuff as human fingernails and rhino horns.)
Primates are the diverse order of mammals that includes monkeys, apes and humans. All primates have shared characteristics, including forward-facing eyes, large brains, opposable thumbs and hands adapted for grasping, as well as relatively long lifespans and slow growth rates.
Julie Elie, an ethologist at the University of California, Berkeley, tells Live Science about using AI to decode the vocalizations of zebra finches.
The surest way to get a scratch from a feline is to go for a forbidden tummy rub. But why do cats hate being touched on their bellies?

A new study revealed that people who rely on AI for basic tasks become less motivated over time. Live Science polled its readers on whether they have experienced this situation.
Researchers hope recursive self-improvement could tackle the skyrocketing costs of developing advanced AI models. But is it viable?
The promise of AI automation to fix the administrative problems facing universities is a fallacy. These systems will only increase the burdens of already-struggling institutions.

A half-built neutrino telescope on the floor of the Mediterranean Sea searched for cracks in one of physics' most basic invariances. It came up empty, but its limits rival those of detectors many times its size.
A hypothetical particle could have briefly held more energy than everything else in the infant universe combined, which could help explain how matter won out over antimatter.
