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.
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.
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.
Nickel is a promising, cost-effective and robust catalyst for alkaline water electrolysis—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 (NiO₂). The findings have been published in the journal Nature Catalysis.
My ancestral languages, Boarisch (Bavarian) and Schwäbisch (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?
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.
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"—areas that host ice sheets and glaciers, such as southern Greenland.
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.
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 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.
