Tiny songbird crosses Sahara on annual migration

Every year a small songbird, no heavier than a letter, crosses the Sahara Desert, the Mediterranean and the Arabian Desert on its migration. New research now reveals how the tiny bird manages this arduous journey.

This flower’s toxic traits hold clues for safer drugs

The molecules of a highly toxic plant, known for its bell-shaped purple and pink flowers and found in some home gardens, have long been used to regulate human heart muscles.

Why natural resource abundance can be a double-edged sword

Natural resources—such as fossil fuels, water, and minerals—are materials found in the environment that are essential for life and highly utilized in production. Though these resources are viewed as essential to economic development and wealth, many resource-rich countries have paradoxically struggled with limited economic growth and unstable political institutions. This phenomenon, known as the “resource curse,” challenges the notion that resource abundance automatically translates into economic prosperity.

Scraped from ancient Roman toilets, these crusted remains expose a pathogen found far earlier than expected

Modern analytical tools are no less than a time machine. From their 21st-century labs, researchers can peer into the everyday lives, hygiene, and even the parasites that plagued the people who lived centuries ago.

These eight coastal cities sit on America’s flood front line, and AI shows why

Severe flooding events have become increasingly common in the United States, partly due to rising sea levels and intensifying hurricane activity fueled by climate change. In addition to the risk to life, these disasters result in billions of dollars of property and infrastructure damage.

From public kissing to talking during movies, a simple formula predicts moral norms across cultures

People living in different countries and societies worldwide can have very different views on what behaviors are acceptable. In the field of sociology, these population-level judgments are broadly referred to as moral and cultural norms.

Microbes contribute a surprisingly large array of proteins in fermented foods

A new study examining the proteins found in fermented foods like yogurt, cheese and bread found that a surprisingly large number, and percentage, of microbial proteins contribute to their overall protein content. These microbes have long been used in traditional fermentation processes and are widely associated with the beneficial or probiotic nature of these fermented foods.

Which types of civilizations collapse and which can endure?

Human history is littered with expired civilizations, and scholars and archaeologists have made a determined effort to understand why and how civilizations collapse. They’ve found that symptoms like a growing wealth gap and distrust of the elites are precursors to civilizational collapse. But what about global technological civilizations like the one we live in now? How long can they last? What causes their collapse? How can they recover?

Classical physics can explain quantum weirdness, study shows

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that same ball down to the size of an atom or smaller, it would behave in ways beyond anything that classical physics can predict. Or so we’ve thought.

Do decoherence, gravity, dark matter and dark energy all originate from quantum corrections?

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely believed to consist of dark matter and dark energy. Paradoxically, however, the nature of these dark components remains unknown. Is this due to limitations in our observational capabilities, or does it reflect a more fundamental incompleteness in the classical laws of physics that have long underpinned our understanding of the universe?

Monkeys in Gibraltar self-medicate with soil to help them digest tourists’ junk food

Researchers monitoring monkey groups across the Rock of Gibraltar have tracked instances of geophagy, and found that animals in frequent contact with tourists eat far more dirt, and that dirt-eating rates are higher during peak holiday season.

This volcano that ‘slept’ for 100,000 years was never truly quiet

For more than 100,000 years, the Methana volcano in Greece appeared dormant. No lava, no explosions, no ash clouds. It appeared extinct, like many other volcanoes today.

The hidden force inside Japan’s 2011 tsunami changed everything

Mud-rich coastlines could face a greater tsunami risk, at least that may have been the case for the 2011 Tohoku-oki tsunami that killed more than 19,000 people and led to the Fukushima Daiichi nuclear disaster. According to a new study mud may have made the catastrophic ocean waves more destructive than they might otherwise have been.

Both bonobos and dolphins form unexpected alliances with ‘outsiders’

Cooperation is a pillar of human society, promoting an exchange of skills and knowledge between different individuals and social groups. This ability to cooperate with “outsiders” has long been considered rare in non-human primates and other animal species.

A new route for plasma-based particle accelerators

Plasma, the fourth state of matter, consists of a gas in which electrons are no longer bound to atoms, which allows electricity to flow freely. When beams of particles moving close to the speed of light travel through plasma, they disturb electrons and drive so-called plasma waves.

Particle thought to break physics followed rules all along, research reveals

More than half a century of measurements of a fundamental property of the muon—the more massive, short-lived cousin of the electron—did not line up with theoretical predictions, raising hopes that new physics might be behind the unexplained inconsistency.

Could the mathematical ‘shape’ of the universe solve the cosmological constant problem?

The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It’s also the source of one of the most enduring and confounding problems in modern physics. The constant’s observed value is fundamentally at odds with quantum field theory (QFT), the leading theory describing the elementary particles and forces that make up the universe.

How poison frogs built a chemical weapons system one evolutionary step at a time

The toxins released by poison frogs, known as alkaloids, are derived from their diet in the wild, which consists of specific ants, mites, millipedes, and beetles. The animals absorb and store alkaloids via a process called sequestration, in some cases modifying them to further increase their toxicity.

People with dark personality traits are naturally inclined towards leadership roles, finds new study

The cold, callous, and sometimes manipulative behavior of people we encounter in everyday life, including at work, may stem from a set of personality traits known as the dark triad—psychopathy, Machiavellianism, and narcissism.

Cardiorespiratory fitness may cut dementia, depression and psychosis risk

Many studies carried out over the past decades have explored the relationship between mental and physical health, showing that the two are often interlinked. One well-established indicator of overall physical health is cardiorespiratory fitness, which is the ability of the heart and lungs to supply oxygen while a person is engaged in sustained physical activity.
