An Ehime University research team directed by H. Shimomoto and E. Ihara has developed a new molecular design strategy that imparts degradability to carbon–carbon (C–C) backbone polymers. The study, published in Macromolecules, demonstrates that incorporating
Vision shapes how many animals find food, avoid danger and navigate their world. In animals with two eyes, eye placement is often linked to lifestyle: predators such as lions tend to have forward-facing eyes that help them judge distance, while prey animals such as deer
Math is great when it's simple, but then our brain gets involved and complicates everything. Imagine you are on the leadership team for a Big 4 and choosing between two employees for a director-level promotion. One is ranked third out of 12 on her team. The other is ranked
Female fertility depends on the successful growth and maturation of eggs (oocytes) within ovarian follicles. Within these follicles, the oocyte is surrounded by granulosa cells that supply nutrients, signaling molecules and structural support essential for egg development.
Cross-coupling reactions have revolutionized the synthesis of complex pharmaceuticals and polymers from simpler, commercially available products. An important first step in these reactions is oxidative addition, which is often facilitated using transition metals such as
Quantum properties of light are extremely delicate. When researchers attempt to measure them, even small losses on the way to a detector can make them invisible, limiting their use outside carefully controlled environments. A collaborative team of researchers involving
Metallic effects on plastic surfaces have become standard in many industries, from automotive interiors and exteriors to toys and household appliances. However, injection-molded parts with metallic effects suffer from a well-known drawback: visible flow lines that appear as
Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly adapt to changes in their environment.
The giant trees of tropical forests are important allies in the fight against climate change because of their ability to store carbon, yet they are still poorly understood by science. However, a study published in the journal Science reveals a crucial survival mechanism: These
Scientists have uncovered why Antarctica became engulfed by ice millions of years before the Arctic. The international research, published in Science, helps solve one of climate science's longest-standing puzzles: how a vast ice sheet could form when Earth was around 5°C warmer

Samples collected at daring heights provide evidence for an untested theory of tree drought adaptation, while countering another.
As temperatures rise around the world, air conditioning is saving lives. But a growing reliance on it is also placing unprecedented pressure on electricity grids, increasing greenhouse gas emissions and making cities even hotter.
Escherichia coli (E. coli) are mostly harmless bacteria that live in the intestines of animals and humans. They are the most well-studied bacteria and, often, when scientists discover something about E. coli, they extrapolate that discovery across all bacteria. So when
Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, physicists have relied on complex equations
Due to their high porosity, metal-organic frameworks (MOFs) are regarded as promising materials for innovative applications, which is why the Nobel Prize in Chemistry was awarded in 2025 for their discovery. They are used, for example, to store gases, to capture CO2 and for the
Indian startup Skyroot Aerospace said Thursday it would hold the maiden test flight of the country's first privately developed orbital-class rocket in the coming weeks.
With El Niño officially declared for summer 2026, Dr. Laura Fernandez and researchers at Macquarie University are testing the use of recycled water to irrigate trees, helping cool Western Sydney.
Nearly 660 kilometers (410 miles) beneath Earth's surface lies one of the planet's most important internal boundaries. Known as the 660-km seismic discontinuity, it separates the mantle transition zone from the lower mantle and plays a central role in controlling how heat and
New Zealand First leader Winston Peters is known for targeting immigrants with inflammatory comments about their place in their new country. He made headlines last year when he urged immigrants who "come here with their ideas, foreign to our country" to "show some gratitude."
A star called TOI-2155 lies around 1,350 light-years (839 trillion miles) from Earth. It is a little bigger, heavier and hotter than the sun, and it is not particularly interesting or unusual in itself.
Australia has a mental health crisis. The Productivity Commission has found mental health issues cost Australia up to A$200 billion to A$220 billion per year—one-tenth of annual economic output.
Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the behavior of the microscopic world, while Einstein's theory of gravity
If you have ever hiked in the high peaks of Colorado, the Wasatch Range in Utah or the Tetons in Wyoming, you've almost certainly seen a rock glacier, perhaps without even knowing it.
The question of how gravity interacts with the quantum world has long perplexed physicists, but a non-quantum theory of space-time could present an answer
For more than a decade, residents of Austin's Colony, a neighborhood in an unincorporated area of southeast Austin outside the city service area, have voiced concern about their tap water's intermittent discoloration and extreme hardness.
Astronomers have revealed new details about the makeup and age of a visiting comet that was born around a distant star. They conclude that the composition of 3I/Atlas is strikingly different from any object found in our solar system.
