Researchers at the University of Kansas (KU) hope to better understand intricate mechanisms behind the evolution of galaxies, which travel through a "cosmic web" of different environments during their lifespans.

As Canadians share more and more genetic data with service providers such as insurance companies or databases like Ancestry.com, the potential for discrimination based on this data is growing. Known as genetic discrimination (GD), this practice is broadly defined as the differential treatment of an individual compared to the rest of the population based on actual or presumed genetic information. Although the Genetic Non-Discrimination Act (GNDA) was passed in 2017 to protect Canadians from GD, a... Читать дальше...

Rebuilding trust in fisheries governance will be vital to create a sustainable industry post-Brexit England, according to new research.

Startups are best known as innovation labs, disruptors that bring new products, services and technologies to market. But their reach goes beyond the products or services they create, according to new research from Texas McCombs.

Stand-out individuals often capture our attention, especially in the United States. According to a recent University of Georgia study, not all nonconformists are the same. Although on the surface, several "stand-out" individuals may look the same, they are likely different from one another in several important ways.

On 28 October 2022, just one day after acquiring Twitter, Elon Musk published a message that summed up his vision for its future: "The bird is free."

Straws are one of the most common plastic waste products found on coastlines. As more and more plastic products are being produced, consumed, and disposed of, scientists and manufacturers are developing alternative materials that work equally as well, and don't contribute to persistent plastic pollution in the environment.

A team of researchers from the URV and the RMIT University (Australia) has designed and manufactured a surface that uses mechanical means to mitigate the infectious potential of viruses. Made of silicon, the artificial surface consists of a series of tiny spikes that damage the structure of viruses when they come into contact with it. The work is published in the journal ACS Nano.

High-entropy alloys can withstand extreme heat and stress, making them suitable for a variety of specific applications. A new study at the X-ray synchrotron radiation source BESSY II has now provided deeper insights into the ordering processes and diffusion phenomena in these materials.

A new discovery by Tel Aviv University has succeeded in cultivating and characterizing tomato varieties with higher water use efficiency without compromising yield. The researchers, employing CRISPR genetic editing technology, were able to grow tomatoes that consume less water while preserving yield, quality, and taste.

In remote Antarctica, Colombian marine biologist Paulo Tigreros dips a net into the icy waters in his hunt for microplastics in what should be one of the best-preserved ecosystems in the world.

Like a moth to flame, many scientists and poets have long assumed that flying insects were simply, inexorably drawn to bright lights.

Researchers have created the first gene drive for the Mediterranean fruit fly (medfly), a global agricultural pest affecting food production. The team was led by Dr. Nikolai Windbichler and Dr. Angela Meccariello at Imperial's Department of Life Sciences, and included researchers from the University of East Anglia and the Hebrew University of Jerusalem. The study is published in Nature Communications.

Hf-based carbides are highly desirable candidates for thermal protection applications above 2,000°C due to their extremely high melting point and favorable mechanical properties. However, as a crucial indicator for composition design and performance assessment, the static oxidation behavior of Hf-based carbides at their potential service temperatures has been rarely studied.

A research team led by Nebraska scientists has built the largest-ever metabolic model of corn to study how temperature stress affects the plant and how a certain fungus can help alleviate the problem.

Poultry scientists with the Arkansas Agricultural Experiment Station are unraveling the complexities of bird brains and finding less expensive ways to do it. The scientists mapped the intricate neurological pathways that control vision in chickens with detailed 3D models of the connections between the eyes and four regions of the brain.

A new study of the Turku PET Center in Finland has shown that music evokes similar emotions and bodily sensations around the world.

Researchers from Skoltech and MIPT and their German, Austrian, and Norwegian colleagues have proposed and tested a new method for computer modeling of magnetic alloys. The method, which relies on machine learning, accurately predicted the energy, mechanical and magnetic characteristics of the alloy of iron and aluminum.

Every fluid—from Earth's atmosphere to blood pumping through the human body—has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter. If the viscosity is higher, the fluid flows calmly, a state known as laminar. If the viscosity decreases, the fluid undergoes the transition from laminar to turbulent flow.

Protein degraders, a novel approach in drug discovery, show promise in tackling diseases previously thought to be untreatable. Unlike traditional drugs that block specific protein functions, degraders alter the cell's natural degradation process so that it can remove disease-relevant proteins. However, resistance to these degraders is still an unsolved issue.

Reliably guiding and capturing optical waves is central to the functioning of various contemporary technologies, including communication and information processing systems. The most conventional approach to guide light waves leverages the total internal reflection of optical fibers and other similar structures, yet recently physicists have been exploring the potential of techniques based on other physical mechanisms.

Scientists studying sunspots have found important clues about magnetic features in their decay that will help understand the evolution and real origin of these mysterious magnetic phenomena. The findings are published in The Astrophysical Journal.

An international team of microbiologists and immunologists has found that commensal gut bacteria develop resistance to antibacterial therapies for infections. In their study, reported in the journal Science Translational Medicine, the group monitored and tested the gut biomes of patients undergoing long-term antibacterial treatment for tuberculosis.

A small team of paleontologists at Museo Nacional de Ciencias Naturales-CSIC has discovered a new species of ancient feline based on study of a jawbone fossil. In their paper published in Journal of Vertebrate Paleontology, the group describes a jawbone fossil uncovered near what is now Madrid, some of its features and where it fits in on the family tree of felines.

The Neolithic age—when agriculture and animal farming were adopted—has become one of the most widely studied periods of social and economic transition in recent years. It was a period that drove great change in the evolution of human society.
