Informal food vendors: The invisible backbone of the world's food system

Walk through almost any city or town in a low-income or middle-income country and you'll pass them: the woman selling deep-fried fish from a cart, the mobile vendor with a bicycle full of vegetables, the kiosk operator who's the only source of a hot meal within walking distance. Food systems employ an estimated 1.23 billion people globally, and a majority of those jobs are informalβ€”unlicensed, unregistered or otherwise outside the reach of formal regulation. In low-income and middle-income countries (LMICs) especially, informal vendors are not a marginal feature of how people eat; they are a linchpin of food security and livelihoods for over a billion people.

Fossil bite marks suggest first evidence of a small raptor feeding on an apex predator

A prehistoric cold case near Drumheller reveals either a small-time raptor scavenged on an apex predator, or a baby Albertosaurus engaged in a shocking act of cannibalism. These two possible explanations for what happened to an Albertosaurus after its death near Drumheller are wildly divergent.

New framework links digital technology and mineral processing to support Africa's economic growth

Research published in the International Journal of Business Innovation and Research (IJBIR) suggests that African economies need to move beyond fragmented development strategies. This might be done by uniting digital technology, startup networks, resource processing and cross-sector partnerships into a single societal innovation ecosystem, the researchers explain.

New 'computational microscope' simulates DNA packaging at more than ten times previous scale

The DNA in our cells wraps around proteins called histones to form nucleosomes, which organize into chromatin. This organization helps pack genetic material into the nucleus and influences how easily genes can be read and DNA damage repaired. Understanding how chromatin changes requires studying molecular movements and interactions that are difficult to capture experimentally.

Chemists uncover the true active surface of nickel catalysts

Nickel is a promising, cost-effective and robust catalyst for alkaline water electrolysisβ€”a key technology for the climate-neutral production of hydrogen. However, the actual structure of the active surface of such nickel electrodes under reaction conditions had not yet been conclusively determined. A research team at Ulm University has now refuted a decades-old assumption: The catalytically active surface does not consist of nickel oxyhydroxide (NiOOH), as was previously widely assumed, but is nickel dioxide (NiOβ‚‚). The findings have been published in the journal Nature Catalysis.

Bavaria's ancestral languages: Resisting linguistic genocide

My ancestral languages, Boarisch (Bavarian) and SchwΓ€bisch (Swabian), are routinely described as German dialects. That might sound like a technical linguistic distinction. For me, a Boarisch-Schwob scholar and community member, it raises a practical question: What happens to a people when their ancestral language, which carries their identity and "Weltanschauung" (worldview), is excluded from protection under a European language treaty because the modern state and dominant culture reduce it to a dialect?

Big dogs age faster at an epigenetic level, new study finds

Great Danes and mastiffs rarely live more than a decade, while Chihuahuas can live twice as long. Exactly why big dogs die younger than small ones do has been unclear β€” but new findings may help to solve that mystery.The research, published Thursday (Oct. 8) in the journal Science, looked at a chemical code written on top of dogs' DNA. This code, called the methylome, consists of chemical tags called methyl groups, which bind to DNA's building blocks. Proteins constantly access DNA, loading up the information written in its code and taking that data away to be turned into new proteins for the cell. But these methyl groups can act as tiny roadblocks that stop that process in its tracks. These...

Lensless imaging method enables long-term monitoring of living cells without staining

In a study led by Tampere University, researchers have developed a new lensless imaging method that produces precise quantitative data on living cells from a single image. The compact system can be placed inside a standard cell-culture incubator, allowing living cells to be monitored continuously for hours or even days without staining or other labels. The research is published in the journal Applied Physics Letters.

Atlantic weather pattern shaped southern Greenland's rain and snow for millennia, sediments reveal

In high-latitude coastal areas, Arctic amplification means that temperatures are rising faster than the global average. This combination of rising temperatures and changing precipitation patterns driven by the North Atlantic Oscillation has major impacts on regions with a "cryosphere"β€”areas that host ice sheets and glaciers, such as southern Greenland.

Do we all see anger the same way?

Happiness, sadness, disgust, surprise, fear, contempt and anger. These are the basic emotions traditionally associated with facial expressions described as universal. As important social signals, facial expressions help us rapidly interpret the emotions and intentions of others. Among these emotions, anger holds a particularly relevant role because it often signals interpersonal threat or conflict.

Real-time oxygen measurements expose hidden losses in solar water splitting

A new technique developed at Imperial College London measures oxygen production in real time, revealing hidden losses in solar water splitting. The researchers found that electrical current did not always correspond to oxygen generation in hematite, one of the most widely studied materials in the field, revealing a previously unknown limitation in the reaction.

Nitrogen fixation 'off switch' discovery could one day help crops make their own fertilizer

Nitrogen is essential for life. It's needed to build proteins, DNA and many other components of cells. Although nitrogen gas makes up almost 80% of Earth's atmosphere, most organisms cannot use it directly. Certain microbes solve this problem through a process called nitrogen fixation, which converts nitrogen gas into ammonia. This process is carried out by an enzyme called nitrogenase.

How enzyme activity can accelerate molecular movement inside cells

A cell sitting in fluid looks like one of the most passive things in biology. Nutrients drift toward it on the aimless currents of molecular motion, and now and then one bumps into the right spot on the cell's surface and gets pulled inside. This impression of the cell as a lottery run by chance, with the molecules wandering and the cell waiting, is a misconception.

'Freakish' discovery of 9 million-year-old capybara tooth supports idea that Atacama wasn't always a desert

An illustration of ancient capybaras enjoying coastal wetlands, which may have looked somewhat like the Atacama Desert around 9 million years ago. (Image credit: Mauricio Alvarez)Researchers have discovered a roughly 9 million year old tooth belonging to a large, water-loving relative of modern day capybaras in the Atacama Desert of northern Chile. The fossilized molar adds to previous evidence suggesting that it's unlikely the Atacama, one of the driest places on Earth, was continuously dry for the last 40 million years.The Atacama Desert, possibly the oldest desert on Earth, takes up the northern third of Chile. It's bounded by the Chilean Coast Range to the west, which blocks rain from th...

Health-promoting imprisonment is being deprioritized, researcher claims

For several decades, Norwegian prison research has focused on the pains of imprisonment, isolation and the harm that prison does. But what is needed for a prison to actually promote health, personal growth and hope? Research shows that what is needed is something quite different from the developments currently underway in Norway.

Nonchaotic model reveals how predictability can emerge from seemingly unpredictable dynamics

Predicting a system's final outcome from its initial state is the ultimate goal for many physicists. In certain complex systems, however, this goal is thwarted by chaos, where even the subtlest tweaks to the initial state can lead to completely different fates, making the system almost impossible to predict.

How information is written in ferroelectric memory at the nanoscale

What happens at the nanoscale when information is written to memory? Researchers at KAIST have shown how tiny regions with a new polarization direction form while previously formed regions continue to expand in a promising ferroelectric material. By linking these nanoscale changes to electrical measurements, the team developed a model that captures both processes, offering a basis for designing faster and more stable memory.
