Recent news on Denisovans

For the summer holidays, Evo in the News will revisit past news items to bring you up to date on recent research and developments. More than a decade ago, the existence of Denisovans was discovered based on DNA extracted from a bone found in a Siberian cave. In the years since, scientists have found more traces of Denisovan DNA – in the Neanderthal and modern human genomes, as well as in remains from that same cave. But we’ve had no direct evidence of Denisovans elsewhere in the world to study…until now. Get the whole story here.

#From de JAMA

She experienced a slow decline over the last decade that was attributable to her dementia. She now needs assistance with all activities of daily living. Most days are consumed by agitation, including episodes of yelling out. Rare moments of lucidity and peace are reserved for loved ones whom she still recognizes in the familiarity of her home. Despite these symptoms, her life is safe and stable. She has family members and caregivers, with whom a coauthor (A.B.M.) collaborates as her physician. She has a voice and a story that still resonate because those who know her best are physically present. Then, the pandemic upended the delicate balance of her life when all of her caregivers, her husband, and finally she became ill from COVID-19.

Vulnerable patients rely on the physical and emotional support of advocates, who are individuals with whom they have connections and who are especially important when critical decisions need to be made about their well-being. Isolating these vulnerable patients from their advocates was an unintended consequence of restricted visitation policies during the pandemic. When the patient described earlier entered the emergency department, hospital protocols prevented anyone from accompanying her inside. Yet, she is unable to provide a history or relate her story. In unfamiliar surroundings with all advocates being denied access, what will happen to her voice./.../

Mathematicians Prove Symmetry of Phase Transitions

By ALLISON WHITTEN

A group of mathematicians has shown that at critical moments, a symmetry called rotational invariance is a universal property across many physical systems.

‘Social’ Mitochondria, Whispering Between Cells, Influence Health

By KATARINA ZIMMER

Mitochondria appear to communicate and cooperate with one another, both within and between cells. Biologists are only just beginning to understand how and why.

A New Kind of Information-Coding Seen in the Human Brain

By ELENA RENKEN

Brain activity is usually measured by the rate at which neurons fire, but new research suggests that exactly when each neuron fires also holds key information.

Optimal Encryption
Black holes scramble information so well that no machine learning algorithm — not even a quantum one — can unscramble it, as physicists Zoë Holmes and Andrew Sornborger write in Scientific American. While we may never decode a black hole’s signals, the information should in theory persist. That’s the conclusion of a recent series of breakthrough papers, as George Musser reported for Quanta last year.

Flash Dance
From a 3D movie of flashing fireflies, researchers confirmed key details of an explanation for why dense swarms of the lightning bugs tend to blink in unison, Sabrina Imbler reports for The New York Times. Fireflies are just one instance of synchrony in nature. Mathematicians recently grappled with new “chimera” systems that only partially sync up, Natalie Wolchover reported for Quanta in 2019.
