Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature's smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics.

Researchers have developed a new technique that vastly improves readings of protein-to-ligand interactions through Raman spectroscopy.

Using ultra-high-precision laser spectroscopy on a simple molecule, a group of physicists has measured the wave-like vibration of atomic nuclei with an unprecedented level of precision. The physicists report that they can thus confirm the wave-like movement of nuclear material more precisely that ever before and that they have found no evidence of any deviation from the established force between atomic nuclei.

Some of the world's most distinct and ancient animal species, which play crucial roles in our planet's ecosystems, are exploited for the wildlife trade across large parts of the world, according to new research.

About 15 years ago, researchers reported that the timing of spring in high-Arctic Greenland had advanced at some of the fastest rates of change ever seen anywhere in the world. But, according to new evidence, that earlier pattern has since been completely erased. Instead of coming earlier and earlier, it seems the timing of Arctic spring is now driven by tremendous climate variability with drastic differences from one year to the next.

Researchers invert a classical approach to modeling food webs. Instead of trying to replicate stable, complex ecosystems using simplistic representations of species interactions, the authors' novel inverse method assumes the ecosystems exist and works backward to characterize food webs that support that assumption. Their work represents a significant step toward addressing a fundamental ecological question of how biodiversity promotes ecosystem stability. The findings offer insights into how nature may respond to growing anthropogenic disturbances.

Scientists found that fires in America's dry conifer forests are burning hotter and killing more trees today than in previous centuries. The main culprit? Paradoxically, a lack of fires.

Researchers have created a quantum superposition state in a semiconductor nanostructure that might serve as a basis for quantum computing. The trick: two optical laser pulses that act as a single terahertz laser pulse.

For lakes in areas with light to moderate road density, the authors found that holding road salt application rates steady could help lakes stabilize below 230 mg/l of chloride per liter of water, the threshold designated by the EPA to protect aquatic life. Reducing application could yield additional environmental and economic benefits without threatening road safety.

Scientists have discovered a new species of marine cryptofauna in the Florida Keys. Cryptofauna are the tiny, hidden, organisms that make up the majority of biodiversity in the ocean. The tiny crustaceans are the first new gnathiid isopod to be discovered from the Floridian ecoregion in 100 years and are named after singer-songwriter Jimmy Buffett.

The new carbon nanotube sensor design resembles a molecular toolbox that can be used to quickly assemble sensors for a variety of purposes -- for instance for detecting bacteria and viruses.

Researchers have created the first tool to map and visualize the areas where human settlements and nature meet on a global scale. The tool could improve responses to environmental conflicts like wildfires, the spread of zoonotic diseases and loss of ecosystem biodiversity.

Scientists have demonstrated experimentally a long-theorized relationship between electron and nuclear motion in molecules, which could lead to the design of materials for solar cells, electronic displays and other applications that can make use of this powerful quantum phenomenon.

In our modern era of larger, more destructive, and longer-lasting fires -- called the Pyrocene -- plants and animals are evolving quickly to survive. By synthesizing the wide body of research about rapid animal evolution in response to fire, a multidisciplinary team of ecology experts hopes to leverage what we already know to help foster evolution-informed conservation plans. In this way, they suggest, we can try to harness the ways in which fire impacts animals to protect vulnerable species -- working with evolution instead of against it.

If, as the saying goes, 'nothing in life is free,' then corals might pay a price for being resilient to climate change. Indeed, the prevailing belief among scientists has been that corals must suffer reduced growth or other tradeoffs when they partner with symbiotic algae that help them tolerate warmer water. Yet, new research demonstrates that certain corals can have their cake and eat it too, and as a result, these coral-symbiont partnerships may come to dominate reef ecosystems in a climate-changed future.

The space laser GEDI has allowed researchers to 3D map Earth's rainforests for the first time ever, helping us understand the forest canopy and providing vital information for understanding Earth's carbon cycle and how it is changing.
