In a new paper published on May 1 in the journal Science Advances, researchers at Columbia Engineering used commercially available tabletop lasers to create tiny, atomically sharp nanostructures, or nanopatterns, in samples of a layered 2D material called hexagonal boron
Immigration has become a defining issue in the 2024 elections and a major challenge in many U.S. cities. Over the past several years, wars and armed conflict, violent persecution and desperate poverty have displaced millions of people worldwide and propelled the arrival in the
The number of individuals in the United States who do not identify as being part of any religion has grown dramatically in recent years, and "the nones" are now larger than any single religious group. According to the General Social Survey, religiously unaffiliated people
Signs written in Spanish are becoming less common along North Philadelphia's Golden Block, or El Bloque de Oro—which runs along North Fifth Street from Lehigh Avenue to Allegheny Avenue and is considered the cultural center of the city's long-standing Puerto Rican community.
It's become common to read that microplastics—little bits of plastic, smaller than a pencil eraser—are turning up everywhere and in everything, including the ocean, farmland, food and human bodies. Now a new term is gaining attention: nanoplastics. These particles are even
Two male students have been expelled from a Melbourne private school for their involvement in a list ranking female students.
Privet is a popular garden hedge. It grows quickly and responds well to being pruned. But in natural areas, privet is a problem.
I met with a friend for a walk beside Merri Creek, in inner Melbourne. She had lived in the area for a few years, and as we walked beside the creek, past trees, native grasses, a small wetland echoing with frog calls, I talked about how it had looked before we started the
Early embryonic development is tumultuous. It involves a rapid sequence of events, including cell division, differentiation, and lots of compartments moving around within each cell. Like an orchestra performance where each member of the band must start playing at the exact
A new study at Hebrew University reveals insights into mRNA regulation during embryonic development. The study sheds light on the intricate process of mRNA regulation during embryonic development, providing novel insights into how pluripotent cells adopt specialized identities
The Brazilian government is discussing the creation of an "agricultural development zone" at the confluence of three states in the Amazon region—Amazonas, Acre, and Rondônia (hence the proposed acronym AMACRO).
Understanding how cancerous cells spread from a primary tumor is important for any number of reasons, including determining the aggressiveness of the disease itself. The movement of cells into the extracellular matrix (ECM) of neighboring tissue is an essential step in cancer
The transition from the African humid period (AHP) to dry conditions in North Africa is the clearest example of climate tipping points in recent geological history. They occur when small perturbations trigger a large, non-linear response in the system and shift the climate to a
Earthquakes are the most dramatic and noteworthy results of tectonic plate movement. They are often destructive and deadly, or at the very least physically felt—they're literally groundbreaking geological events. However not all tectonic movement results in effects that humans
Perhaps dark matter is made of an entirely different kind of particle than the ones physicists have been searching for. New experiments are springing up to look for these ultra-lightweight phantoms. The post Dogged Dark Matter Hunters Find New Hiding Places to Check first
Researchers from Skoltech and their colleagues have investigated nerve cell regulation. Mounting knowledge of regulation mechanisms could enable a better understanding of how the healthy brain operates and what goes wrong in developmental and oncological diseases associated
Insects and microorganisms that feed on plants, cut up leaves, modify leaf tissue or produce leaf spots and other kinds of damage, are usually known as pests and considered harmful, yet interactions between plants and their natural enemies are important sources of biodiversity.
The discovery of sympathetic nervous system cells in lampreys draws a closer tie between the animal and complex vertebrates — such as humans.
Understanding mutational processes in a cell offers clues to the evolution of a genome. Most actively, mutation processes are studied in human cancer cells, while other genomes are often neglected.
Drug delivery researchers at Oregon State University have developed a device with the potential to improve gene therapy for patients with inherited lung diseases such as cystic fibrosis.
Since their discovery, researchers have repeatedly demonstrated the potential medical applications of differentiated cells and tissues generated from induced pluripotent stem (iPS) cells. However, a significant hurdle to real-world medical applications is related to the
The whole is greater than the sum of the parts. The post Why Animals Run Faster than Robots appeared first on Nautilus .
A team of oceanographers and planetary scientists at the Ocean University of China, working with a pair of colleagues from the U.S. and one in Germany, has found via computer modeling, that recent heat waves in the north Pacific may be due to a large reduction in aerosols
In the early 20th century, the development of a catalyst for ammonia synthesis by the Haber-Bosch method took more than 10,000 experiments before it was successful. The development of new materials is a time-consuming and costly process from design to commercialization.
Migrasomes, novel organelles first reported by Professor Li Yu' s team in 2015, are vesicular structures with diameters ranging from 0.5 to 3 micrometers that form on the retraction fibers at the rear of migrating cells. These structures contain various biomolecules such as
A collaboration has led to the identification, in a bacterium of the intestine, of new CRISPR-Cas9 molecules that could have a clinical potential to treat genetic diseases such as retinitis pigmentosa, through sub-retinal injections. Anna Cereseto and Nicola Segata of the
A new computational model simulating fruit fly wing development has enabled researchers to identify previously hidden mechanisms behind organ generation.
