More than 3.5 billion years ago, the Earth was not the hospitable world we know today. The atmosphere lacked oxygen, the seas were acidic and rich in iron, and volcanic activity roared across a barren landscape. Yet, in this alien world, something extraordinary happened—life
For every US$1 the world invests in protecting nature, it spends US$30 on destroying it. This stark imbalance is the central finding of a new UN Environment Program (UNEP) report released today. It calls for a major shift in global financing of nature-based solutions and
Beyond their sparkle, diamonds have hidden talents. They shed heat better than any material, tolerate extreme temperatures and radiation, and handle high voltages while wasting almost no electricity—ideal traits for compact, high-power devices. These properties make
Alzheimer’s may be driven far more by genetics than previously thought, with one gene playing an outsized role. Researchers found that up to nine in ten cases could be linked to the APOE gene — even including a common version once considered neutral. The discovery reshapes how
Over the past few years, studies have suggested that plastic particles from bottles, food packaging and waste have been detected in human blood, lungs, placentas, arteries and even the brain. But a recent investigation by The Guardian suggests that some of these claims may be
The retirement of West Midlands police chief Craig Guildford is a wake-up call for those of us using artificial intelligence (AI) tools at work and in our personal lives. Guildford lost the confidence of the home secretary after it was revealed that the force used incorrect
Space agencies are no longer talking about visiting the moon, they're planning on living on it.
The British astronomer and mathematician Edmond Halley was not, after all, the first to understand the cycle of the comet that now bears his name. This is shown by research conducted by, among others, Professor Simon Portegies Zwart. It was the monk Eilmer of Malmesbury who, as
A research team has investigated quasar variability by tracking optical to mid-infrared (MIR) wavelengths of variability information. This multiband joint analysis provides an opportunity to probe the dust structure in the quasar's central region and holds promise for revealing
Whether it be singing, dancing or crafting, engaging in the arts is good for our health, and we're beginning to understand how this behaviour affects our biology
In Guatemala’s Western Highlands, researchers found that the drinking water people trust most may actually be the riskiest. Bottled water from refillable jugs—seen as the safest choice—was frequently contaminated with harmful bacteria, while protected municipal wells were the
It is hard to imagine that anyone could have missed the fact that such economic crashes occur from time to time—crashes that could have terrible consequences for individuals and society. In recent history, many vividly remember the IT bubble that burst twenty-five years ago
Researchers at the Max Planck Institute for Extraterrestrial Physics (MPE), in collaboration with astrophysicists from the Centro de Astrobiología (CAB), CSIC-INTA, have identified the largest sulfur-bearing molecule ever found in space: 2,5-cyclohexadiene-1-thione (C₆H₆S).
It's no secret that Florida's iconic coral reefs are in trouble. Repeated body blows from hurricanes, pollution, disease, climate change—and a near-knockout punch from a 2023 marine heat wave—has effectively wiped several species off the map and shrunk the reefs that stretch
Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.
A study of dolphins’ epigenetic ages found that animals with more high-quality friendships were biologically younger than their lonely peers
New research suggests that auditory hallucinations in schizophrenia may come from a brain glitch that confuses inner thoughts for external voices. Normally, the brain predicts the sound of its own inner speech and tones down its response. But in people hearing voices, brain
Two extremely damaging crop pests have interbred to create hybrids resistant to more than one pesticide that could cause serious problems in many countries
A new research study found that well-managed fisheries can support the recovery of large marine predators such as seals and porpoises, showing that conservation and sustainable seafood production can go hand in hand. While the impacts of protected species are often debated, the
A rare fossil discovery in Ethiopia has pushed the known range of Paranthropus hundreds of miles farther north than ever before. The 2.6-million-year-old jaw suggests this ancient relative of humans was surprisingly adaptable, not a narrow specialist as once believed. Instead
Rare rocks buried deep in central Australia have revealed how a valuable niobium deposit formed during the breakup of an ancient supercontinent. More than 800 million years ago, tectonic rifting opened pathways that allowed metal-rich magma to rise from the mantle. These
A partial skeleton dating back more than two million years is the most complete yet of Homo habilis, one of the earliest known species in our genus
With already thin profit margins and increasingly uncertain farm labor and other input costs, precision agriculture technology could improve New England's small and medium-sized farms' efficiency, productivity, and resilience. Unfortunately, factors such as up-front costs and
From planet-scorching stellar outbursts to cataclysms so powerful they shiver the very fabric of spacetime, these are some of the biggest blasts our cosmos has to offer
Europa’s subsurface ocean might be getting fed after all. Scientists found that salty, nutrient-rich surface ice can become heavy enough to break free and sink through Europa’s icy shell, delivering essential ingredients to the ocean below. The process is fast, repeatable, and
Researchers are using cutting‑edge DNA techniques to hunt for genetic evidence in centuries‑old artworks in an effort to better understand the genius of Leonardo da Vinci
A comprehensive new review published in the Journal of Management synthesizes decades of research to understand the epidemic of workplace loneliness. By analyzing 233 empirical studies, researchers from Portland State University have identified how workplace conditions

Your chronological age can’t always tell you the state of your health, which is why biological clocks have been developed to show our risk of developing diseases or dying – but they’re not all they are cracked up to be, says columnist Graham Lawton
New research published in Nature Ecology and Evolution reveals significant recent shifts in tree diversity among the tropical forests of the Andes and Amazon, driven by global change.
Winter has its fans, but even those who enjoy playing in the snow probably dislike the chore of clearing up after a big storm that dumps several inches or even feet of snow and ice.
A team from Würzburg has fundamentally changed our understanding of platelet biology. The researchers demonstrate that the surface protein integrin αIIbβ3 is not only a key molecule in blood clotting, but can also act as a pro-inflammatory effector during severe disease
An unusually brutal winter storm is set to pummel more than 160 million Americans from Friday, as a stretched "polar vortex" sends a devastating blast of Arctic air, bringing heavy snows and freezing rains.
Chemists at UCLA are showing that some of organic chemistry’s most famous “rules” aren’t as unbreakable as once thought. By creating bizarre, cage-shaped molecules with warped double bonds—structures long considered impossible—the team is opening the door to entirely new kinds
Many species of fungus across the world produce psilocybin, a chemical with psychedelic effects in humans, but its evolutionary purpose may be to deter mushroom-munching insects
The North Atlantic Ocean is warming up. Higher temperatures and increased human activity in the region can trigger abrupt changes in marine ecosystems, for example, how species are distributed and what they eat.
A new study suggests humans belong in an elite “league of monogamy,” ranking closer to beavers and meerkats than to chimpanzees. By comparing full and half siblings across species and human cultures, researchers found that long-term pair bonding is unusually common in our
Researchers have identified a promising new weapon against triple-negative breast cancer, one of the most aggressive forms of the disease. An experimental antibody targets a protein that fuels tumor growth and shuts down immune defenses, effectively turning the immune system
Research on using Marchantia polymorpha, commonly known as liverwort, a plant closely related to moss, for food and as an ingredient in medicine and supplements is being conducted at Kobe University.
A new study combines drone data, satellite observations, and ground-based flux measurements to examine methane emissions from ruminants in Kenya. The research represents a pioneering effort to quantify methane (CH₄) emissions from livestock using drones in sub-Saharan Africa.
Colorado will not release more wolves this winter to supplement its reintroduction program after federal officials stopped the planned relocation of wolves from Canada.
Worldwide, it ranks among the cities with the highest levels of air pollution—and it's located in the heart of Europe: Sarajevo, the capital of Bosnia and Herzegovina. Previously, the spatial distribution of air pollutants here was largely unknown, as were their sources. Now
Even as NASA celebrated the rollout of the Space Launch System rocket and Orion spacecraft for Artemis II over the weekend, NASA's new administrator, Jared Isaacman, made sure to put an asterisk on the program's future.
