Fading lights: Multiple threats to North America's firefly populations      (via sciencedaily.com)     Original source 

Scientists have applied a data-driven approach to understanding firefly population dynamics on a continental scale. Key findings from this new study indicate that fireflies, part of the beetle order, are sensitive to various environmental factors, from short-term weather conditions to longer climatic trends, including the number of growing-degree days related to temperature accumulations.

Astronomers' simulations support dark matter theory      (via sciencedaily.com)     Original source 

Computer simulations by astronomers support the idea that dark matter -- matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe -- exists, according to the researchers.

Atomic nucleus excited with laser: a breakthrough after decades      (via sciencedaily.com)     Original source 

For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new field of research with many technological applications. Now, nuclei can be used for extremely precise measurements. For example, a nuclear clock could be built that could measure time more precisely than the best atomic clocks available today.

Physicists show that light can generate electricity even in translucent materials      (via sciencedaily.com)     Original source 

Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists have managed to prove this.

The end of the quantum tunnel      (via sciencedaily.com)     Original source 

Quantum mechanical effects such as radioactive decay, or more generally: 'tunneling', display intriguing mathematical patterns. Researchers now show that a 40-year-old mathematical discovery can be used to fully encode and understand this structure.

From disorder to order: Flocking birds and 'spinning' particles      (via sciencedaily.com)     Original source 

Researchers have demonstrated that ferromagnetism, an ordered state of atoms, can be induced by increasing particle motility and that repulsive forces between atoms are sufficient to maintain it. The discovery not only extends the concept of active matter to quantum systems but also contributes to the development of novel technologies that rely on the magnetic properties of particles, such as magnetic memory and quantum computing.

More efficient molecular motor widens potential applications      (via sciencedaily.com)     Original source 

Light-driven molecular motors were first developed nearly 25 years ago. However, making these motors do actual work proved to be a challenge. In a new paper, scientists describe improvements that bring real-life applications closer.

Climate change could become the main driver of biodiversity decline by mid-century      (via sciencedaily.com)     Original source 

Global biodiversity has declined between 2% and 11% during the 20th century due to land-use change alone, according to a large multi-model study. Projections show climate change could become the main driver of biodiversity decline by the mid-21st century.

These jacks-of-all-trades are masters, too: Yeast study helps answer age-old biology question      (via sciencedaily.com)     Original source 

The results suggest that internal -- not external -- factors are the primary drivers of variation in the types of carbon yeasts can eat, and the researchers found no evidence that metabolic versatility, or the ability to eat different foods, comes with any trade-offs. In other words, some yeasts are jacks-of-all-trades and masters of each.

Unveiling the lionfish invasion in the Mediterranean Sea      (via sciencedaily.com)     Original source 

Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.

Hurricanes jeopardize carbon-storing New England forests      (via sciencedaily.com)     Original source 

Many American companies are relying on carbon offsets to reduce their carbon footprint, especially those who have pledged to achieve 'net-zero emissions.' Sequestering carbon in forests is an example of a nature-based solution that is being used to address climate change, but a new study suggests that hurricanes could pose a risk. The results show that a single hurricane may wipe out 5% to 10% of total above-ground forest carbon, through tree damage, in New England.

Diversity and productivity go branch-in-branch      (via sciencedaily.com)     Original source 

Researchers found that forests with higher trait diversity not only adapt better to climate change but may also thrive. The study unveiled how tree functional trait diversity plays a pivotal role in mitigating climate warming. In the face of environmental stress, these diverse trees have been shown to maintain higher productivity levels, in contrast to monoculture forests.
