The analysis of DNA from 1,300-year-old skeletons allowed the reconstruction of the health status of the Merovingian community in in Lauchheim "Mittelhofen" in today's Baden-Württemberg.

A new study has found that young Brits would be willing to change to a more sustainable diet, but a lack of understanding about what that actually means is preventing many from doing so.

Spiral galaxies represent one of the most spectacular features in our universe. Among them, spiral galaxies in the distant universe contain significant information about their origin and evolution. However, we have had a limited understanding of these galaxies due to them being too distant to study in detail.

Non-vascular photoautotrophs (NVP), including mosses, lichens, terrestrial algae and cyanobacteria, are organisms that receive their energy from light but lack the vascular tissue that transports water and nutrients in vascular plants. Lacking roots, they rely on direct uptake of water from the atmosphere or from the near-surface layer of the soil.

A new computational analysis by theorists at the U.S. Department of Energy's Brookhaven National Laboratory and Wayne State University supports the idea that photons (a.k.a. particles of light) colliding with heavy ions can create a fluid of "strongly interacting" particles. In a paper just published in Physical Review Letters, they show that calculations describing such a system match up with data collected by the ATLAS detector at Europe's Large Hadron Collider (LHC).

A new study from the University of Georgia found many states within the Southeast and West qualify as financial advice deserts—a new concept coined by researchers to describe a low proportion of financial planners or planning institutions where people are less likely to understand their financial options or save for the future.

Microbiome engineering is at the forefront of improving human health and agricultural productivity. It aims to enhance ecosystem function by altering microbe composition. This can be accomplished through a "bottom-up" approach involving the introduction of engineered microbes into a community.

An insidious category of carcinogenic pollutants known as "forever chemicals" may not be so permanent after all.

University of Washington geologists had set out to create computer-based field experiences long before the COVID-19 pandemic hit. Juliet Crider, a UW associate professor of Earth and space sciences, first sent a former graduate student and a drone to photograph an iconic Pennsylvania geological site and pilot a new approach to field geology.

Changes in Earth's orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago that is considered an analog for modern climate change, according to an international team of scientists.

WNT signaling is crucial for the development of organisms and the maintenance of tissue homeostasis, since the WNT messengers are involved in a variety of cellular functions. In skeletal muscle, for example, they can increase muscle mass and improve regeneration. This is an important entry point for therapies to treat diseases associated with reduced muscle mass, such as cachexia.

A team of UT researchers from the Faculties of ITC, BMS and ET has recently published a new study in the International Journal of Applied Earth Observation and Geoinformation that found using digital twins can improve planning and coordination in cities. Digital twins are digital representations of physical objects or systems, and have been widely used in manufacturing, construction, and maintenance to improve planning and coordination. Now, researchers are exploring how they can be adapted to serve cities and their complex, dynamic ecosystems.

Images of the protests that followed the death of 22-year-old Mahsa Zhina Amini on Sept. 16, 2022, in Iran and reports of the government's brutal crackdown have circulated widely on social media. This flow of information comes despite efforts by the Iranian regime to throttle internet access and censor information leaving the country.

New research from the University of Hertfordshire reveals the acute extent of food poverty amongst immigrants in the U.K. who have no access to welfare benefits, with widespread reports of food shortages and lack of appropriate support.

Snow days, a nostalgic rite of passage for generations of students across the northern United States, might seem destined to be a memory of school days past. For nearly a century, schools have canceled or delayed classes because of heavy or dangerous snowfall that creates hazardous travel conditions. School calendars would include a number of "makeup" days, when any missed time could be rescheduled.

During the COVID-19 pandemic, food pantries across the country pivoted to create "mobile" options, repurposing school buses or using large tractor-trailers to deliver food to different neighborhoods.

As western water managers get set to gather in Las Vegas this week, a long-sought deal to curtail water use along the cratering Colorado River still seems a ways off.

In Boston, there are reports of people pronouncing the letter "r." Down in Tennessee, people are noticing a lack of a Southern drawl. And Texans have long worried about losing their distinctive twang.

Antibiotic resistance, when infection-causing bacteria evolve so they are no longer affected by typical antibiotics, is a global concern. New research at the University of Tokyo has mapped the evolution and process of natural selection of Escherichia coli (E. coli) bacteria in the lab.

Curtin University researchers have revealed how the pelvic fins of fish such as sharks and chimeras have evolved from their sudden appearance in the fossil record over 410 million years ago.

For years, cosmologists had thought that a strange feature appearing in the microwave sky, known as the CMB cold spot, was due to the light passing through a giant supervoid. But new research casts that conclusion into doubt.

It's the most wonderful time of the year… not because Christmas is coming, but because it's time for the Geminid meteor shower—an annual spectacle to bring joy and good cheer to all.

With biodiversity declining at unprecedented rates and less than a decade remaining to avert the worst effects of climate change, world leaders and policymakers are on the hunt for new and innovative solutions. In the halls and meeting rooms of global COP conferences, digital technologies have been heavily promoted to address these interrelated threats to our ecosystem.

You saw it at Thanksgiving, and you'll likely see it at your next holiday feast: piles of unwanted food—unfinished second helpings, underwhelming kitchen experiments and the like—all dressed up with no place to go, except the back of the refrigerator. With luck, hungry relatives will discover some of it before the inevitable green mold renders it inedible.

Dark matter makes up about 27% of the matter and energy budget in the universe, but scientists do not know much about it. They do know that it is cold, meaning that the particles that make up dark matter are slow-moving. It is also difficult to detect dark matter directly because it does not interact with light. However, scientists at the U.S. Department of Energy's Fermi National Accelerator Laboratory have found a way to look for dark matter using quantum computers.
