Observing one-dimensional anyons: Exotic quasiparticles in the coldest corners of the universe
Scientists have observed anyons -- quasiparticles that differ from the familiar fermions and bosons -- in a one-dimensional quantum system for the first time. The results may contribute to a better understanding of quantum matter and its potential applications.

Kinetic coupling -- breakthrough in understanding biochemical networks
A new concept of kinetic modules in biochemical networks could revolutionize the understanding of how these networks function. Scientists succeeded in linking the structure and dynamics of biochemical networks via kinetic modules, thus clarifying a systems biology question that has been open for longtime.
Mid-air transformation helps flying, rolling robot to transition smoothly
Engineers have developed a real-life Transformer that has the 'brains' to morph in midair, allowing the drone-like robot to smoothly roll away and begin its ground operations without pause. The increased agility and robustness of such robots could be particularly useful for commercial delivery systems and robotic explorers.
A sweeping study of 7,000 years of monuments in South Arabia
New research brings together 7,000 years of history in South Arabia to show how ancient pastoralists changed placement and construction of monuments over time in the face of environmental and cultural forces.
Huge sea-urchin populations are overwhelming Hawaii's coral reefs
This study measured the growth rate of coral reefs in Honaunau Bay, Hawaii, using on-site data gathering and aerial imagery. Researchers found that the reefs are being eroded by sea urchin populations which have exploded due to overfishing in the area. The reefs are also threatened by climate change and water pollution, and their growth rates are not fast enough to counteract the erosion caused by the urchins.
Bed bugs are most likely the first human pest, new research shows
Researchers compared the whole genome sequence of two genetically distinct lineages of bed bug, and their findings indicate bed bugs may well be the first true urban pest.
Nearly five million seized seahorses just 'tip of the iceberg' in global wildlife smuggling
Close to five million smuggled seahorses worth an estimated CAD$29 million were seized by authorities over a 10-year span, according to a new study that warns the scale of the trade is far larger than current data suggest. The study analyzed online seizure records from 2010 to 2021 and found smuggling incidents in 62 countries, with dried seahorses, widely used in traditional medicine, most commonly intercepted at airports in passenger baggage or shipped in sea cargo.
Researchers engineer a herpes virus to turn on T cells for immunotherapy
A team identified herpes virus saimiri, which infects the T cells of squirrel monkeys, as a source of proteins that activate pathways in T cells that are needed to promote T cell survival.
New AI tool reveals single-cell structure of chromosomes -- in 3D
In a major leap forward for genetic and biomedical research, scientists have developed a powerful new artificial intelligence tool that can predict the 3D shape of chromosomes inside individual cells -- helping researchers gain a new view of how our genes work.
Ongoing surface modification on Jupiter's moon Europa uncovered
A series of experiments support spectral data recently collected by the James Webb Space Telescope that found evidence that the icy surface of Jupiter's moon Europa is constantly changing. Europa's surface ice is crystallizing at different rates in different places, which could point to a complex mix of external processes and geologic activity affecting the surface.
Timing, consistency of activity linked to better fitness
The timing and consistency of your daily activity might be associated with improved cardiorespiratory fitness and walking efficiency.
Cosmic mystery deepens as astronomers find object flashing in both radio waves and X-rays
A team of international astronomers have discovered a new cosmic object emitting both radio waves and x-rays.
Solitonic superfluorescence paves way for high-temperature quantum materials
A new study in Nature describes both the mechanism and the material conditions necessary for superfluorescence at high temperature.
Coastal Alaska wolves exposed to high mercury concentrations from eating sea otters
Scientists show that wolves that are eating sea otters in Alaska have much higher concentrations of mercury than those eating other prey such as deer and moose.
Mother's warmth in childhood influences teen health by shaping perceptions of social safety
Parental warmth and affection in early childhood can have life-long physical and mental health benefits for children, and new research points to an important underlying process: children's sense of social safety.
When the forest is no longer a home -- forest bats seek refuge in settlements
Many bat species native to Germany, such as the Leisler's bat, are forest specialists. However, as it is becoming increasingly hard for them to find tree hollows in forest plantations, so they are moving to settlements instead. Using high-resolution GPS data from bats, a team led by scientists has analyzed in greater detail than ever before how Leisler's bats use their habitats, which tree species they look for when searching a roost, and which forest types they avoid. They found that these bats increasingly seek refuge in old trees in urban areas and in old buildings such as churches.
Intestinal bacteria influence aging of blood vessels
The aging of the innermost cell layer of blood vessels leads to cardiovascular diseases. Researchers have now shown for the first time that intestinal bacteria and their metabolites contribute directly to vascular aging. As people age, the bacterial composition in their gut changes, resulting in fewer 'rejuvenating' and more harmful substances in the body.
New chiral photonic device combines light manipulation with memory
Engineers have developed a multifunctional, reconfigurable component for an optical computing system that could be a game changer in electronics.
Research untangles role of stress granules in neurodegenerative disease
Scientists found that stabilizing stress granules suppresses the effects of ALS-causing mutations, correcting previous models that imply stress granules promote amyloid formation.
Whether it's smoking or edibles, marijuana can be bad for your heart, study suggests
A new study finds that chronic cannabis use -- whether it's smoked or consumed in edible form -- is associated with significant cardiovascular risks.
Electric buses struggle in the cold, researchers find
Researchers have released new insights on a pilot program involving all-electric buses in Ithaca, NY, USA -- with implications for cities, schools and other groups that are considering the electrification of their fleets, as well as operators, policymakers and manufacturers.
